Evaluation of Dawson Ginger Myanmar teak solid wood floor: insufficient high temperature resistance, but extremely strong water resistance - evaluation of solid wood floor

2017-02-16 10:03:42 Source: Views: eight thousand and ninety-six

Chinese traditional culture worships rosewood culture, while in western culture, teak is included in the category of worship. European and American countries believe teak is a better wood and is widely used. With the increasing internationalization of China's culture, the higher the openness to the world, the higher people's awareness of teak. Myanmar teak overcame Solid wood flooring Common defects such as easy deformation, cracks and large shrinkage, and release its own woody fragrance, showing natural charm.

Driven by interests, there are many fake solid wood floors in the market. It really takes some effort to buy a real Myanmar teak solid wood floor in the market. In this issue, we will evaluate a Myanmar teak solid wood floor: Dawson Ginger Myanmar teak solid wood floor, the market price is 1050 yuan/㎡ In this evaluation, we found that this teak floor has excellent antifouling performance, but its high temperature resistance makes us a little embarrassed. Compared with the round bean solid wood floor, the high temperature resistance of Dasenginger's floor is indeed lacking! So, what about the other properties of this Myanmar teak solid wood floor? Is it worth buying?

Opening point

In the evaluation of the round bean solid wood floor, although the high temperature resistance did not get five stars, there were no serious problems after being burned by cigarettes. In contrast, the performance of Myanmar teak solid wood floor would be much worse.

 Solid wood floor evaluation Solid wood floor evaluation

Similarly, after the cigarette was burned out, we observed the changes of the burned part of the solid wood floor, and wiped the ashes with a cloth, but there were still black spots that could not be wiped off, and there were still some ashes embedded in the surface cracks that could not be wiped off. In addition, some bubbles caused by high temperature burning can be clearly seen at the burning part. Compared with the test of round bean solid wood floor, the high temperature resistance performance of Myanmar teak is even worse. These problems can only show that the high temperature resistance of this Burmese teak floor is very weak. Therefore, if you choose this floor, you should avoid dropping cigarette butts on the floor or contacting other high temperature sources in daily use to prevent damage.

Part 1 Appearance

1.1 Appearance impression

 Solid wood floor evaluation Solid wood floor evaluation

This teak floor is full of oil and bright wood, full and classic color, very delicate hand feel, neat and meticulous texture, and gives off a noble temperament. Therefore, if it is used to create European classical style, it should be a good choice. On the one hand, teak flooring has always been loved by the West, and on the other hand, it originally contains the beauty of natural elegance.

1.2 Width measurement

 Solid wood floor evaluation

The width given by the manufacturer is 125mm. We measured the three floors with vernier calipers, and the data obtained are all about 125.2mm, with an error deviation of about 0.2mm. The standard deviation of width of solid wood floor in China is ≤ 0.30mm, so the deviation of width of this floor is in line with the standard.

1.3 Thickness measurement

 Solid wood floor evaluation

Also use vernier caliper to measure the thickness of the floor. The reading is 18.12mm, which is only 0.12mm error compared with the value of 18mm given by the manufacturer. The deviation is too small to affect the paving effect of the floor, and there will be no obvious discomfort when people step on it.

For this kind of small floor, due to the need for multiple floors to be spliced when paving, there are many joints, and the probability of concealing dirt is also increased. The owner will be hard to clean, but the small and uniform paving effect is very good, stable, and not easy to deform.

Part 2 Details

2.1 Process evaluation

 Solid wood floor evaluation

Dawson Ginger Myanmar teak solid wood floor has a lasting and classic color, golden yellow brown, demonstrating classical charm. We can see that the floor texture is very beautiful, the ink lines are smooth and natural, and there is a faint fragrance overflow, and the natural style is natural. However, when viewed from the side, it is found that the side process is not perfect, the lines are rough, stiff, and not neat enough. If you touch them with your hands, you can feel the burrs scraping your hands.

2.2 Floor connection mode

 Solid wood floor evaluation

The floor adopts tongue and groove connection, which has high stability, good sealing and convenient operation. We personally spliced the two floors, which is not difficult to operate, but because the notch is not smooth and tidy enough, the connection is not compact enough, and we can see from the picture that they are not satisfied with each other.

 Solid wood floor evaluation

In order to test the firmness of the splicing, we lifted one side of the floor, and the floor was steadily and vertically downward without detachment. It can be seen that the splicing of this floor is very firm. Compared with the splicing of round bean solid wood floor, the effect is much better.

 Solid wood floor evaluation

We tested the tightness of this floor splice by dripping water at the seam. Five minutes later, the floor was disassembled. Not only was there water stains at the dripping place, but most of the notches were stained with water stains, indicating that the splice was not tight enough. However, this is not necessarily a bad thing, because the floor will deform according to the temperature and humidity of the environment. If the floor is spliced too tightly, it will bulge when it expands, and if it is too loose, it will shrink into a larger gap.

2.3 Back

 Solid wood floor evaluation

The workmanship of the back is good, which can explain whether the merchants are careful in design. In general, we need to evaluate whether there is a logo on the back of the floor, whether there is a moisture-proof substrate, and what designs can help stabilize the pavement. By observing the back of the floor, we clearly saw the logo of the business and laid a layer of moisture-proof substrate. Because the surface is rough, the friction between the floor and the ground is increased, and the pavement will be more stable.

Part 3 Performance Test Diagram

3.1 Pollution resistance test

 Solid wood floor evaluation

The test can prove that this solid wood floor is also very stain resistant. Like the round bean solid wood floor, it has a strong defense against stains.

In life, we often rub oil stains on the floor. In order to further evaluate the stain resistance of this Burmese teak floor, we use pepper oil for testing.

 Solid wood floor evaluation

After standing for 10 minutes, wipe with a paper towel, and the oil stain is wiped clean, leaving almost no residue. If you can easily deal with chili oil, you can basically face the dirt you often encounter in daily life without pressure.

3.2 Skid resistance test

This test is completed in two ways, first with a spring dynamometer and a 500g steel block, and then with a paper cup filled with water on the inclined floor surface.

 Solid wood floor evaluation

The surface of the solid wood floor evaluated in these two times is relatively smooth, and the values measured by the spring dynamometer are also relatively low. We put a 500g steel block on the floor surface, and the test shows that it needs at least 3N force to pull the steel block. The strength of 3N is really small for a healthy person. Therefore, our preliminary conclusion is that the slip resistance of this Myanmar teak is poor.

 Solid wood floor evaluation

Place a paper cup filled with more than half of the cup of water on the floor surface placed at an angle (to prevent the friction between the bottom of the paper cup and the floor from being increased due to water, we have wiped the water at the bottom with a dry cloth), and observe the state of the paper cup on the floor after releasing the hand. As soon as I released my hand, the paper cup slipped down quickly and the tester caught it in time. If there is some resistance on the floor surface, the paper cup cannot slide so fast.

How about the skid resistance of this Myanmar teak solid wood floor? We can already give the answer, that is, "the skid resistance is not enough and needs to be improved". If there are old people, children, or pregnant women in the home, the use of this floor may be in danger of slipping.

3.3 Abrasion resistance test

Similarly, in addition to using steel blocks and sandpaper to test the abrasion resistance of the floor, we will also use the key to cooperate with the test.

 Solid wood floor evaluation

There is a 500g steel block on the 600 mesh sandpaper. Pull one end of the sandpaper with hands at a constant speed to observe the abrasion marks left by the sandpaper on the floor. Why use 600 mesh sandpaper and 500g steel block? Because the larger the mesh size, the more delicate the sandpaper is. The 600 mesh size is exquisite enough for home use; The 500g steel block represents the weight of the object in general. After sliding, there is obviously abrasion mark of sandpaper, but after wiping with cloth, the mark is almost invisible.

Then, we use the key to test the abrasion resistance of the floor surface.

 Solid wood floor evaluation

The key scratched hard on the floor surface, trying to leave traces. In order to make the observation more clear, we wiped the dust off the surface, but even in the bright place, there was almost no scratch on the key. In a word, the wearability of this Myanmar teak solid wood floor is OK. If it is very full, you can get at least 8 points. Usually, high heels are rubbed on the floor twice more, and the owner does not have to worry about damaging its beauty.

3.4 Surface hardness test

 Solid wood floor evaluation Solid wood floor evaluation

Under the pressure of 1000g, the 6H pencil left a very clear black scratch on the floor surface. After wiping with a cloth, you can still see the traces one by one. At one end of the floor, as shown in the figure above, we have wiped the graphite layer with cloth for many times, but we still cannot wipe it off. It seems that it has been firmly embedded in the wood.

 Solid wood floor evaluation

In order to continue to test the hardness of the floor, the tester stood on the inclined floor in person, and no deformation of the floor was found by naked eye observation. In general, the surface hardness of the floor is not enough to resist scratching of hard objects, but the overall hardness of the floor is very good.

3.5 Impact resistance test

 Solid wood floor evaluation

The ball fell from a height of 1m to the floor surface, as shown in the figure, and very clear craters can be seen. Similar to the evaluation results of the round bean solid wood floor, the impact resistance of the floor is not enough. Although there is no phenomenon of being broken or cracked, it is still smashed out of a small hole. For the floor with poor impact resistance, we must try to avoid heavy objects falling on the floor, otherwise we will be distressed if we are hit.

3.6 Environmental protection test

 Solid wood floor evaluation

The environmental protection of solid wood flooring has always been the focus of owners. For this solid wood floor, we need to check whether formaldehyde meets the standard. According to the test rules, we read the measured values 5 minutes after the test. The Hygienic Standard for Formaldehyde in Indoor Air in China is 0.08mg/m3, and the data measured this time is 0.031mg/m3, which is completely lower than the standard value. We have reason to say that the environmental protection of this solid wood floor is trustworthy!

3.7 Soaking test

 Solid wood floor evaluation

Immerse one end of the floor vertically in 5cm deep water, and observe the changes of the floor after standing for 24 hours. The next day when we observed the test results, we saw a very gratifying scene: the water soaked in the floor is still clear. We still clearly remember that when testing the water resistance of the round bean solid wood floor, the water in the basin was slightly red... When observing the surface of this floor, there was no swelling problem, but through naked eye observation, the side lines were still straight. This is just a comment based on feeling, which is not enough evidence. We used vernier caliper again to measure the thickness, and the data obtained was 18.12mm, which was the same as the data before the test! It can be seen that this is a solid wood floor with excellent water resistance!

Part 4 Summary

Rainy weather is frequent in the south, so you can use this floor, so you can not be afraid of the humid and changeable climate. But it should also be reminded that families with children, the elderly and pregnant women should be careful to use them to prevent falls.

After carefully evaluating this solid wood floor, I always feel a little regret in my heart. This Myanmar teak solid wood floor of Dawson Ginger has excellent environmental protection. The owners can use it with confidence. It also has strong stain resistance. The product process is also good. Even if it is soaked in water for 24 hours, it will not have deformation problems. However, the high temperature resistance is not enough. In terms of skid resistance, surface hardness, and impact resistance, the performance is just normal. If other performance manufacturers can also work hard, this floor is a conscience floor and worthy of users' favor.

  •  What are the types of water-based wood coatings?
    What are the types of water-based wood coatings?

    What are the types of water-based wood coatings? Although there are many brands of water-based wood paint in the current market, there are different classifications according to the different main components. What are the types of water-based wood paint? Types of water-based wood paint 1. The water-based wood paint with acrylic acid as the main component is characterized by good adhesion, which will not deepen the color of the wood, but poor wear resistance and chemical resistance, soft film hardness, pencil rule HB, poor fullness, general comprehensive performance, and easy to produce defects in construction. Because of its low cost and low technical content, it is the main product of most water-based paint enterprises to the market. This is also the reason why most people think that water-based paint is not good. Its advantage is cheap. 2. The water-based wood paint, which is mainly composed of the synthesis of propylene and polyurethane, not only inherits the characteristics of acrylic paint, but also has the characteristics of strong abrasion resistance and chemical resistance. Some enterprises mark it as water-based polyester paint. The film hardness is good, the pencil rule is 1H, the fullness is good, and the comprehensive performance is close to that of oil paint. As of 2018, only a few domestic enterprises can produce. 3. The polyurethane waterborne paint has superior comprehensive performance, high fullness, film hardness of 1.5-2H, abrasion resistance even better than that of oil paint, and obvious advantages in service life and color blending. It is a senior product in waterborne paint. 4. For pseudo water-based paints, curing agents or chemicals, such as "hardener", "film enhancer", "special diluent", etc., should be added when using. Some can also be diluted with water, but the solvent content is very high, which is more harmful to human health, and some even exceed the toxicity of oily paints. Some enterprises label water-based polyester paint. Consumers can easily distinguish them.

  •  What are the application methods of water-based paint?
    What are the application methods of water-based paint?

    What are the application methods of water-based paint? At present, there are many kinds of paints on the market, including water-based paint. Many people will have many doubts when buying water-based paint, because water-based paint does not contain organic solvents, and it uses water as the diluent. What are the application methods of water-based paint? Use method of water-based paint 1. If the humidity is greater than 80%, it is not suitable for construction, because the paint film is prone to whitening and other problems. 2. Clean the floating dust regularly, and then keep the wood surface neat and stable. 3. If the temperature is appropriate, know the temperature well. If the temperature drops below 5 ℃, the drying time of the paint will be prolonged, and the paint cannot be exposed to direct sunlight. 4. Painting procedure When painting, pay attention to the impact on the wall emulsion paint. Generally, paint the wall first, and then paint after the completion of water-based paint construction. 5. The wood quality construction shall know the wood material, and the hardwood can be painted directly. For ordinary wood, the transparent putty shall be used as the substrate before painting. 6. The coating shall be thin rather than thick. During multi-layer coating construction, each coat shall be applied after the lower layer is completely dry, and each coat shall be polished. 7. The timely construction shall be well proportioned, and then mixed evenly. The air bubbles caused by mixing shall be discharged before use. The paint shall be used up within 4 hours after the proportioning is good. 8. Pay attention to safety when painting, because paint is flammable.

  •  What are the steps in the construction process of water-based paint?
    What are the steps in the construction process of water-based paint?

    Construction process of water-based paint? Nowadays, in the process of home decoration construction, people often use water-based wood paint. As a kind of environment-friendly paint with water as diluent, its characteristics of low pollution and low harm are gradually favored by more and more owners. The construction of water-based paint is also very important. What are the steps in the construction process of water-based paint? Waterborne paint construction process 1. Base material treatment: the moisture content of wood base material shall not be higher than 12%. If there is a sense of moisture when touching with hands, construction is not allowed. The base material shall be kept clean and flat, and the surface shall be free of oil stain, glue and other impurities. If there is any stain, it shall be removed in time. 2. Putty scraping: during construction, putty shall be applied from top to bottom, from left to right. Generally, it shall be applied twice. Each time, it shall not be too thick, and it shall be kept as flat as possible without leaving traces, so as not to affect subsequent construction. 3. Brush primer: when using the primer, add 5%~10% water to dilute it, and mix it evenly. The primer needs to be painted three times, with an interval of 2-3 hours between each process. After drying, use 400 # sandpaper to polish. 4. Brush finish paint: when using the finish paint, add 5%~10% water to dilute it, and mix it evenly. Generally, the finishing coat shall be painted twice, and the interval between each process shall be 2-3 hours. After drying, it shall be polished with 800 # sandpaper. 5. If the oily primer has been applied before the water-based wood paint is applied, it can be polished with 400 # sandpaper before the water-based wood paint is applied, so as to increase the surface adhesion. 6. When applying wood primer, the relatively rough substrate shall be polished with 360-400 # sandpaper first, and the primer can be applied only after the grinding dust is removed; The dust that has entered the wood grain can be removed with a brush or wet towel.

  •  What are the precautions for water-based paint construction?
    What are the precautions for water-based paint construction?

    What are the precautions for water-based paint construction? The construction of water-based paint needs to add clean water by oneself, so the technical difficulty required is relatively large, and it depends very much on the operating experience of the constructor. It is particularly important to master its construction technology and operate in strict accordance with the specifications. What are the precautions for water-based paint construction? Precautions for water-based paint construction 1. The construction conditions of water-based wood paint are: temperature 10 ℃ – 30 ℃, relative humidity 50% – 80% (preferably 25 ℃, humidity ≤ 70%). If the construction conditions cannot be met, small area tests shall be carried out first to avoid construction defects. 2. The temperature of water-based wood paint shall be consistent with that of the surface to be painted. It is not allowed to paint on wood with low temperature. Although the water-based wood paint can be applied and dried in the sun, it should be avoided to paint on the hot surface. The properties of the two are different. 3. When painting on the vertical surface, add 5% – 10% clean water in the paint solution for dilution, and then paint by spraying or brushing. The coating should not be too thick, and the amount of paint dipped should be small to prevent sagging. 4. If the paint liquid is too thick during construction, it can be properly mixed with clean water for commissioning, and the amount of water added depends on the situation. 5. The number of construction times depends on the required quality and effect, and usually 3-4 times can achieve good results. 6. Before painting, the compatibility of the used water paint with the primer or colorant must be confirmed. 7. Although the surface of water-based wood paint dries quickly, it takes a long time for all the moisture in the paint film to escape. Generally, it can reach the best state after 7 days of drying.

  •  How about the performance of water-based paint? What are the disadvantages?
    How about the performance of water-based paint? What are the disadvantages?

    How about the performance of water-based paint? With the pressure of environmental protection policies, consumers' awareness of environmental protection continues to improve; In particular, provinces and cities across the country have issued VOC emission limit standards, encouraging the use of non solvent paints, water-based paints and other environmental friendly coatings, which has brought opportunities for development. How about the performance of water-based paint? What are the disadvantages? Performance of water-based paint (1) Poor pigment dispersion. Waterborne paint belongs to polymer dispersion system, and pigment dispersion is not very good, so measures must be taken to improve it. (2) The stability of dispersed particles is poor. Dissolved molecules are stable to shear force, heat, pH, etc., while dispersed particles are unstable, so stability measures should be taken for the dispersion system. Dispersed particles will be damaged after being subjected to shear force, so it is necessary to consider avoiding the role of shear force in the process of manufacturing and transporting water-based paint. Dispersed particles are very sensitive to pH value, and acid particles will be formed when acid substances are mixed into the paint, thus causing gelation and destruction of water-based paint. In addition, dispersed particles of water-based paint will also be damaged after freezing during transportation. (3) High surface tension. The surface tension of water is large (see Table 2), so the surface tension of water-based paint is also large. Management should be strengthened during the construction process, otherwise the following defects and film defects are likely to occur during coating: a. easy sagging; b. Poor flattening; c. It is easy to produce shrinkage cavity and pinhole; d. It is not easy to stretch into the small cracks on the surface of the coated object. (4) The evaporation heat and heat capacity are high and are greatly affected by temperature and humidity. The high evaporation heat and heat capacity of water (see Table 2) slow the evaporation of water in water-based paint. 50% of the total amount of solvent in solvent based paint evaporates during spray atomization, while only 25% for water-based paint. Slow evaporation of water is easy to cause sagging during painting, and makes painting efficiency worse. Therefore, an intermediate heating zone is required to volatilize water from the water-based primer coating. Before spraying varnish, 90% of water must be removed from the water-based primer coating (to prevent boiling water from volatilizing through the varnish during final baking) to obtain the best paint film appearance, so as to prevent the water-based primer from being re dissolved by the varnish. The evaporation rate of water is closely related to the relative humidity. When the relative humidity is high, the evaporation rate of water is very low. Therefore, the relative humidity and temperature of the spray booth must be controlled within a certain range to ensure that an appropriate amount of water is volatilized during the spray atomization process, and that water and organic solvents are properly balanced in the film. This proper balance is very important, which can make the paint have proper surface tension to wet the sprayed surface (see Table 2). (5) Good conductivity. The dielectric constant of water is large (see Table 2), so the conductivity of water-based paint is good. Generally, the resistance of water-based paint is less than 0.1M Ω), while solvent based paint has a certain resistance: 0.5~20M Ω. Waterborne paint has good conductivity, and there are special requirements when electrostatic spraying is used. (6) High corrosivity. The water-based paint contains a lot of water, so it is corrosive to containers, transmission pipelines, paint booth and other parts vulnerable to moisture. Stainless steel or plastic products are required. (7) Rheological behavior. When the viscosity of fluid decreases with the increase of shear rate, it is called pseudoplastic fluid. The rheological behavior of pseudoplastic fluid is related to its rheological path, that is, it is time dependent, so it is called thixotropic fluid. Based on the characteristics of water-based paint, the viscosity value measured by flow cup does not have reproducibility, and the complete rheological curve of data points including low shear rate and high shear rate measured by rotary viscometer can give the complete characteristics of rheological behavior of water-based paint. Disadvantages of water-based paint 1. The water-based paint has high requirements on the cleanliness of the surface during construction and materials. Because of the large surface tension of water, dirt is easy to cause shrinkage of the film; 2. The dispersion stability of water-based coatings against strong mechanical forces is poor. When the flow rate in the transmission pipeline changes sharply, the dispersed particles are compressed into solid particles, causing pockmarks in the film. The conveying pipeline shall be in good shape and the pipe wall shall be free from defects. 3. Waterborne coatings are highly corrosive to coating equipment, so anti-corrosion lining or stainless steel materials are required, and the equipment cost is high. The corrosion of water-based coating on the transmission pipeline and the dissolution of metal cause the precipitation of dispersed particles and the pitting of the coating film. Stainless steel pipes are also required. 4. Baking water-based coating has strict requirements on construction environmental conditions (temperature and humidity), which increases the input of temperature and humidity regulating equipment and energy consumption. 5. The evaporation latent heat of water is large, and the baking energy consumption is large. Cathodic electrophoretic coating shall be baked at 180 ℃; However, the time for latex coating to completely dry is very long. 6. Organic cosolvent with high boiling point will produce a lot of oil smoke during baking, which will drop on the surface of the film after condensation and affect the appearance.

    What are the advantages of water-based paint? How about the effect?

    What are the advantages of water-based paint? Waterborne paint is now the choice of many home decoration. Waterborne paint is harmless to human body, does not pollute the environment, and the paint film is plump, which is favored by many users. What are the advantages of water-based paint? How about the effect? Advantages of water-based paint: 1. Use water as solvent to save a lot of resources; Eliminate the fire hazard during construction; Reduce air pollution; Only a small amount of alcohol ether organic solvents with low toxicity are used to improve the working environment. Generally, the organic solvent of water-based coatings (accounting for coatings) is between 5% and 15%, while cathodic electrophoretic coatings have been reduced to below 1.2%, which has a significant effect on reducing pollution and saving resources. 2. Waterborne coatings can be applied directly on wet surfaces and in wet environments; Good adaptability to material surface and strong adhesion of coating. 3. Coating tools can be cleaned with water, greatly reducing the consumption of cleaning solvent and effectively reducing the damage to construction personnel. 4. The electrophoretic coating is even and flat. Good flattening performance; The inner cavity, weld, edges and corners can be coated with a certain thickness of film, which has good protection; The electrophoretic coating has the best corrosion resistance, and the salt spray resistance of thick film cathodic electrophoretic coating can be up to 1200h. How to distinguish true and false water-based paint 1. The main agent and curing agent of the real two-component water-based paint are basically odorless or only slightly odorous after opening the can; 2. The real two-component water-based paint is diluted with clean tap water. If special diluent or alcohol is needed to dilute it, it must not be; 3. The two-component water-based paint also belongs to non hazardous chemicals, while the fake two-component paint is often flammable dangerous goods; 4. Look at the environmental protection index: whether it contains benzene, heavy metals, high VOC and other toxic substances.

    What are the characteristics of pe pipe? How about environmental protection?

    What are the characteristics of pe pipe? Plastic pipes are developing steadily. PE pipes, PP-R pipes and UPVC pipes all have a place, among which the strong development momentum of PE pipes is the most eye-catching. PE pipes are widely used. What are the characteristics of pe pipe? How about environmental protection? What are the characteristics of PE pipe? 1. Softness: because PE-RT is relatively soft. Therefore, no special tools are needed during construction, so the construction cost is relatively low. 2. Thermal conductivity: pipes used for floor heating need to have good thermal conductivity. PE-RT has good thermal conductivity, and its thermal conductivity is twice that of PP-R and PP-B pipes. It is very suitable for floor heating. 3. High temperature resistance: The high temperature resistance of PE-RT can reach 90 ℃, while that of PEX can only reach 65 ℃. 4. Low temperature heat shock resistance: PE-RT has good low temperature shock resistance. During winter construction, the pipes are not easy to be impacted and broken, which increases the flexibility of construction arrangement. 5. Environmental protection: PE-RT and PP-R can be recycled without polluting the environment. However, PEX can not be recycled, which will cause secondary pollution; 6. Stability of processing performance: PEX has problems such as controlling the crosslinking degree and crosslinking uniformity. The processing is complex and directly affects the pipe performance. The processing of PE-RT, PP-R is simple, and the properties of the pipes are basically determined by the raw materials, so the properties are relatively stable. PE-RT is the abbreviation of Polyethylene Raised Temperature. It is copolymerized by ethylene monomer and 1-octene monomer. It is a medium density ethylene octene copolymer specially designed for heating systems. It has a special molecular structure with narrow molecular weight distribution and octene evenly distributed on the main chain of the polymer. It retains the original health and processing properties of PE, It is also a new type of special material for pipes with enhanced high-temperature durability. The pipes produced with this raw material are mainly used in the field of hot water/heating pipes in buildings. Their durability is the same as the service life of buildings, with a minimum of 50 years. At the same time, they have good recoverability and high added value.
