Fair faced concrete and GRC components are made of CTI Comus COM AS Advantages of EAL permanent condensate DPS
Brand: COMASEAL, CTI Kermis.
Briefly describe the advantages: 1. The permanent condensate DPS imported from the United States is a pure inorganic material, which is anti-aging and UV resistant (only true imports are acceptable, but fake, shanzhai and fake foreign devils are definitely not acceptable), and can be more than 20 years old;
2. Acid and alkali resistance and corrosion resistance. Alkali resistance: Soak in saturated calcium hydroxide solution for 168 hours (PH value is about 12), and there is no pulverization and crack on the surface. Acid resistance: soak in 1% hydrochloric acid solution for 168 hours (PH value 1-2), and the surface is free of pulverization and cracks;
3. It can be used in harbor engineering. Chloride ion permeability resistance: ≤ 1000 C (refer to JTJ 275-2000 Specification for Concrete Corrosion Protection of Port Engineering);
4. The anti freezing and thawing cycle can be more than 1000 times. The storage period is more than 5 years. The product is very stable and does not deteriorate;
5. Simple construction, no leveling layer and protective layer. Can be matched with inorganic coating And change the color of the exterior wall structure other Complete combination of protective products;
6. GRC components of different materials, as cast finish concrete and different products can meet different performance requirements.
DPS， It is the abbreviation of Deep Penetration Sealer. In the definition of domestic national standards, it is water-based (or water agent, water-based) permeable crystalline inorganic waterproof material. American CO-MA-SEAL permanent condensate DPS waterproof material was used in the United States earlier than the 1920s, mainly for large areas of underground military bunkers, etc., playing the role of waterproof and moisture-proof.
U.S.A C O -MA-SEAL ® （ CTI Komis) Permanent condensate DPS waterproof material is Water based permeable crystalline waterproof material (The advantage of water-based is that when there is water in the concrete structure, it can continue to react until the water is "absorbed"). Its waterproof mechanism is to produce chemical reaction with free alkali and other active ingredients in the concrete, generate stable dendritic crystal colloid, effectively block the micro cracks and capillary voids in the concrete, so that the concrete structure has good waterproof function and better compactness and compressive strength. The permeability of high layer reaches about 30mm. At the same time, it can effectively prevent the erosion and damage of acid and alkali substances, oil stains, algae, salt, etc. to concrete.
It can be used for any concrete base surface. Other series of products are recommended for other structural planes.
American CO-MA-SEAL permanent liquid DPS waterproof material is not only concrete waterproof material, but also concrete protective agent: it is acid resistant, alkali resistant, corrosion resistant, and can resist high temperature changes! It can also resist the damage and erosion of chloride ions on concrete.
Main advantages:
1、 American CO-MA-SEAL (CTI Kermis) permanent condensate DPS waterproof material is permeable crystalline waterproof material, so leveling layer is not required. It can completely penetrate into the concrete structure, so no protective layer is required;
2、 It needs to be fully contacted with the concrete to achieve a good waterproof effect, so the laitance and dust on the surface of the concrete structure must be cleaned up first. Rapid solidification shall be used at the crack first cement Wait for repair;
3、 It is a waterproof material with small density of water agent, which can be sprayed evenly on the concrete base without additional curing. Low construction cost and fast construction progress;
4、 The penetration degree of the high layer can reach about 30mm (general concrete). The impermeability grade is above P11;
5、 Good acid, alkali and corrosion resistance (PH value 2-12). It can resist the influence of temperature change on concrete. It can resist the penetration damage of chloride ion to concrete. It can enhance the compressive strength of concrete structure surface, etc;
6、 American CO-MA-SEAL permanent condensate DPS waterproof material is inorganic waterproof material, so it will not deteriorate. The effect is very stable. After construction, the waterproof efficiency is basically the same as the service life of the concrete structure;
7、 It can be constructed on the wet concrete working surface, but there should be no open water. It can be constructed on the back surface;
8、 Because it is a deep penetration crystalline waterproof material, there will be no traditional problems such as aging, untight lapping, delamination and sliding;
9、 It can play a good role in protecting concrete, reinforcement, etc;
10、 It is completely environmentally friendly and harmless, with VOC<2g/L. It can be used as the interior wall of swimming pool, sewage pool, water plant, etc;
11、 Because it is a deep penetration crystalline type, it is not a surface sealed bead, but hydrophilic.
Special reminder: the waterproof material of American permanent liquid DPS is water agent, colorless and tasteless, so there are many counterfeits. It depends on whether there is an import declaration form, certificate of origin, etc. The permanent condensate DPS imported from the United States is * * * permanent condensate DPS. Compared with the domestic ones, the quality gap is too large and the price is absurdly low (material cost per square meter). There are many so-called English brands in the market that are counterfeit imports! Search on Google or Yahoo (Baidu can only search domestic) to see if there are relevant manufacturer websites, brands, construction cases and other materials abroad, so as to identify the authenticity! You can also check the time when a so-called English brand registered its trademark in China at a glance! The so-called domestic production of American technology is more untrustworthy, because there is no relevant evidence!
