Solid waste paint is solidified due to insufficient sealing work in the air, or being in the air for a long time and being idle for a long time after expiration. Although it has no recycling value, it can be used as a good fuel.
The recycling value of waste paint is the scrapped paint in the inventory. The inventory, especially due to the expiration of time, has not been opened. The recycling load is used by the clock, so the value, of course, if the color is uniform, is.
This year, due to the impact of macro-control, the real estate industry was suppressed, and the recovery of waste paint was intensified. As soon as the purchase restriction policy was issued, the overall chemical industry was affected by the earthquake, the market demand, the recycling of waste paint was also less, and the waste paint market was depressed.
In addition, the labor cost and raw material cost are both high, and the future of the domestic real estate market is uncertain, which has a great impact on the chemical industry. On the positive side, though the impact is great, it can still be maintained. The normal survival of the fittest has been taking place all the time. The future market trend remains to be seen.
With the increasingly fierce competition in all walks of life, more and more people are engaged in the waste paint recycling industry. People who just started the waste paint recycling industry are usually confused. Although more and more people are engaged in the recycling industry, it is necessary to understand that the society is constantly developing. No matter chemical enterprises, petroleum enterprises and other enterprises are springing up like mushrooms, the more these chemical enterprises are, the greater the output of waste paint will be. Therefore, the recycling industry of waste paint has a very broad development space and is trying to break through the bottleneck, Realize social green environmental protection and healthy and orderly development of the industry
Classify the recovered waste paint, and do not mix it. Put the waste paint into a rectangular tank, add double water, and then add a certain amount of special solvent. Soak it for a day or two. If the air flotation coagulant in the waste paint is added, add a certain amount of auxiliary agent when soaking, and then dehydrate it, add a suitable solvent, grind and mix it, tell separation, take out mechanical impurities, filter it, Additive and leveling agent. New paint can be dried or self drying.
After the waste paint is recycled and treated, if it is found that the glossiness is poor, a proper amount of brightener should be added. These can be applied to the surface of the garage, carriage, bridge, etc. It is usually the same as the new paint, and the cost is only half of the new paint. This is environmentally friendly and cost saving, and will not cause problems because of reuse.
Waste paint is defined as deteriorated, expired, residual paint and inventory. These paints are prone to problems if put into normal use because of deterioration or expiration. However, these waste paints are still available. The waste paint can be recycled, processed and reused. After recycling, the waste paint can be reprocessed and put back into use. Yes material.
For waste paint recycling, we need to find a regular waste paint recycling company, but we need to know that one kind of waste paint treatment cannot be recycled, that is, the paint that becomes solid has no recycling value. There is no uniform treatment price. Usually, the price is determined according to the waste paint, and the quantity is large. This is to remind the masses that waste paint is harmful and should not be dumped randomly. We can find a regular recycler to recycle it to avoid pollution.
As a large developing country, with rapid development, there is a lot of industrial waste inevitable, especially waste oil paint, which is often seen in construction and decoration, and even in all walks of life. But at present, many waste paints are recycled. Generally, we all know that waste paint will cause great pollution to the atmosphere, but dumping it at will will also cause pollution to land resources, and fire will also be caused if it is not handled well. So how to deal with the waste paint recycling?
For paint, many of them are toxic. Untreated and stacked at will will pose a great threat to people's life and property health. In fact, we should consider the road of development. For waste paint itself, it is a kind of thing that can be reused, but we preconceived that waste paint is unusable. So how to deal with it? The choice is to recycle, reprocess and reuse the waste paint.
The discoloration of paint and coating is a common phenomenon in home decoration construction. Some people think that it is a problem of paint and coating, which may occur, but it is caused by improper operation in most cases. The discoloration of paint and coating is generally caused by the color deepening on the original basis.
Causes of paint discoloration:
1. The ester solvent in the varnish reacts with the iron container and turns black after encountering water.
2. Turpentine is easy to form red brown pigment in iron drums.
3. Gold and silver powder and varnish are prone to acid corrosion, which makes the paint green, dark and lusterless.
4. The storage period is too long, and the sediment is discolored.
Avoid:
1. Shellac varnish that is prone to discoloration shall be packed in non-metallic containers.
2. Before applying varnish, add gold powder and silver powder. Do not deposit in varnish too early.
3. If it is not a problem for the paint and coating with precipitated discoloration, it can still be used after stopping the full mixing.
Science and technology are productive forces, and innovation is an important driving force for the continuation of science and technology. At present, the homogenization of products in the paint market is serious. Although the homogenization phenomenon has met the business needs of small paint enterprises,
However, it is quite disadvantageous for the overall development of the paint industry. In the long run, it is also the development of paint enterprises. It is difficult for ordinary consumers to distinguish between various types of environmentally friendly paint, latex paint and wall paint.
At this time, product differentiation is particularly important. The innovation of paint enterprises can effectively save production costs and production efficiency, and the products can be more easily accepted by the market with correct and effective publicity means.
As early as the Shang Dynasty, China had taken down natural lacquer decorative appliances, palaces and temples from lacquer trees. By the Spring and Autumn Period, we had mastered the technology of refining tung oil to make coatings. In the Warring States Period, we could use raw paint and tung oil to mix coatings. The technology of using additives in coatings promoted the development of coatings to a new era.
The tough and protective film of lacquer coffins and lacquerware unearthed from the Han Tomb at Mawangdui in Changsha fully shows the maturity of the development of the use of raw lacquer technology in China in the 2nd century BC. As a result of the application of tung oil and lacquer, the customary name of "paint" has been handed down.
In the last century, the major achievements in the theory of polymer science and the successful development of various polymer compounds were put into production, which has developed a new era for paint. In the 1920s, alkyd resin used as film forming material of coatings was successfully developed. Since then, various newly developed synthetic resins have been quickly applied in coatings, making coatings enter an era dominated by synthetic film forming materials.
Nitrocellulose varnish. Nitrocellulose varnish is a kind of transparent paint made of nitrocellulose, alkyd resin, plasticizer and organic solvent. It belongs to volatile paint and has the characteristics of fast drying, soft luster, etc. Nitrocellulose varnish is divided into high gloss, semi matt and matt, which can be selected according to needs. Nitrocellulose paint also has its disadvantages: it is easy to whiten in high wet weather, low fullness, and low hardness
1. Phenolic paint has fast drying, high hardness, water resistance, abrasion resistance, but is brittle and prone to yellowing.
2. Nitrocellulose paint is wax gram, which is fast in drying, hard in film, wear-resistant and clear in wood grain, but poor in film fullness.
3. Alcohol ester paint is easy to construct, firmly attached, bright and plump, and is commonly used for painting outdoor wood products, such as doors and windows, railings, and steel structures. However, its film is relatively soft and has poor water resistance, so it is not suitable for floor and desktop.
4. The advantages of unsaturated polyester paint are good fullness, fast drying speed, and suitable for industrial production line.
5. Polyamine ester paint has excellent hardness, toughness, wear resistance and strong decorative property, but contains TDI.
