Paint knowledge | what is polymer cement waterproof material

Core tip: waterproof materials are essential for building waterproofing With the progress of production technology and the increasing demand of people, there are more and more kinds of waterproof materials in the market Today we introduce polymer cement waterproof materials Let's have a look! What is polymer cement waterproof materials Polymer cement based waterproofing coating (also known as JS waterproofing coating) is a waterproof coating developed gradually in the field of building waterproof coating in recent years It is a two component water emulsion architectural waterproof coating with organic polymer emulsion and inorganic powder as the main raw material It has both rigidity and the necessary toughness Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: waterproof materials are essential for building waterproof With the progress of production technology and the increasing demand of people, there are more and more kinds of waterproof materials in the market Today we introduce polymer cement waterproof materials, let's have a look! What is polymer cement waterproof materials Polymer cement based waterproof coating (also known as JS waterproofing coating) is a waterproof coating developed gradually in the field of building waterproof coating in recent years It is a two component water emulsion architectural waterproof coating with organic polymer emulsion and inorganic powder as the main raw material It has a certain rigidity and the necessary toughness It can be described as "rigid and flexible." Polymer cement-based waterproof coating is based on water as dispersant, which overcomes the disadvantages of the past waterproof coating with tar and asphalt as solvent, which is easy to pollute the environment It is a kind of environment-friendly coating, to a certain extent, in line with the requirements of sustainable development, so it is more and more valued by people and has become one of the hot spots in the development of waterproof coating in recent years The waterproof principle of polymer cement waterproof material is analyzed from the existing varieties of waterproof coating, and its waterproof mechanism can be divided into two types One is to form a complete film to block the penetration of water or water molecules; the other is to prevent the penetration of water through the film itself through its hydrophobic effect Polymer cement waterproof coating is to block the penetration of water or water molecules by coating There are always some gaps between the molecules of solid polymers, the width of which is about several nanometers It is reasonable to say that a single water molecule can pass through these gaps completely, but water in nature is usually in association state, and dozens of water molecules form a large water molecular group due to the effect of hydrogen bond In this way, it is difficult for water molecules to pass through the gap between polymers, which is the main reason why the waterproof coating film has the waterproof function Standard Specification for polymer cement waterproof materials when using polymer cement waterproof coating, we should pay attention to that the construction temperature should be higher than 5 ℃ in rainy days, which is not easy to construct, and the surface decoration construction can only be carried out after the surface of polymer cement waterproof coating is dry The storage of polymer cement waterproof coating shall be placed at a place of no less than 0 ° C during transportation, attention shall be paid to preventing rain and exposure to the sun, as well as moisture The national standard of polymer cement waterproof coating has clear regulations The tensile strength is ≥ 1.2MPa; elongation at break: ≥ 200%; adhesive strength: ≥ 0.50mpa; drying time (H): surface drying ≤ 4h, actual drying ≤ 8h; low temperature flexibility: (- 10 ℃, 2h) no crack; water permeability: (0.3MPa * 30min) water-proof Price of polymer cement waterproof material 1 Paint film color: gray white, brand: etrun, liquid type: reactive, origin: Shandong, net weight of single piece: 20kg / barrel, price: 150.00; 2 Paint film color: gray | brand: Guangzhou Dayu waterproof | liquid type: reactive | origin: Guangzhou | net weight of single piece: 20kg, 10kg, price: 190.00; 3 Film color: white, surface dry time: 8, brand: Haiyun, liquid type: two-component, origin: Changsha, price: 480.00 About what polymer cement waterproof material is introduced here, I hope to help you Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
