Coating general knowledge: performance and characteristics of cement-based permeable crystalline waterproof coating

Core tip: the cement-based permeable crystalline waterproof coating is a kind of powder mixture made of Portland cement, silica sand and active chemicals, which is the advanced rigid waterproof material in the world It has the characteristics of infiltrating crystallization, corrosion resistance, increasing the density of concrete and improving the strength of concrete It can grow into a branch like needle crystal inside the concrete This crystal becomes an integral part of the concrete It can prevent the infiltration from any direction and achieve the purpose of permanent waterproof It is internationally known as "biological cement" Cement based permeable crystalline waterproof coating can be widely used for underground people Paint knowledge | precautions for wall paint color selection Recommended introduction: when painting the wall, the owner sometimes has difficulty in choosing what color of the wall paint to paint In fact, there is no ugly color in the wall paint, only the disharmonious color matching The use of wall color contains the knowledge of health Too strong color will stimulate people's perception, make people have a sense of fidgety, affect people's mental health Grasp the basic principles of wall color and paint a colorful space 1、 Wall paint color selection notice 1 Light color is generally used for the top surface Light colors make people feel light, dark colors make people feel heavy Usually, the treatment of rooms is from top to bottom, from shallow to deep For example, the ceiling and walls of rooms are white and Coating home news: cement-based permeable crystalline waterproof coating is a kind of powder mixture made of Portland cement, silica sand and active chemicals It is an advanced rigid waterproof material in the world It has the characteristics of infiltrating crystallization, corrosion resistance, increasing the density of concrete and improving the strength of concrete It can grow into a branch like needle crystal inside the concrete This crystal becomes an integral part of the concrete It can prevent the infiltration from any direction and achieve the purpose of permanent waterproof It is internationally known as "biological cement" Cement based permeable crystalline waterproof coating can be widely used in underground civil air defense waterproof engineering, tunnel waterproof, bridge and culvert waterproof, drinking pool, swimming pool and other waterproof engineering projects The characteristics of cement-based permeable crystalline waterproof coating: 1 It can automatically repair defects, and the active substances sealed by the coating can produce secondary crystallization at the defects of the base layer when encountering water It has the function of automatically repairing microcracks and other defects, and has strong resistance to the changes of the base layer 2 Good physical and chemical properties: strong permeability and surface alkali resistance 3 Good waterproof effect: it can truly achieve one-time construction, durable waterproof, except for the trouble of repair 4 Good environmental protection performance: This product is non-toxic, tasteless and pollution-free, and can be used for drinking water What is the difference between the cement-based waterproof coating and the cement-based permeable crystalline waterproof coating? The cement-based permeable crystalline waterproof coating is rigid waterproof It is used to produce chemical reaction on the surface of concrete structure It has the ability of secondary impermeability, non-toxic and pollution-free It is one of the green environmental protection waterproof materials advocated by the state National standard GB / 18445-2001 The scientific name of cement-based waterproof coating is polymer cement waterproof coating, which belongs to flexible waterproof coating with different executive standards Waterproof construction of waterproof roof with cement-based permeable crystalline waterproof material 1 Check whether there are any holes and seams before construction If there are holes and seams, it can be repaired with dry strong waterproof coating 2 Brush with 1.2-1.5kg per square meter of concentrated waterproof coating 3 Fill the earth seven days after the construction of basement outer wall 4 For basement waterproof with high humidity, dry and strong waterproof coating can be used to speed up the waterproof construction of dry pile foundation on the surface 1 Clear the loose structure of pile foundation surface 2 If there is water seepage, use fast plugging agent to plug the leakage 3 Use concentrated waterproof coating with the amount of 1.5kg per square meter to brush the post cast strip waterproof construction 1 Use fast plugging agent to plug the leakage at the water seepage place of the post cast strip 2 If there is a water tight crack, chisel the crack into a 'U' shape and fill it with a dry strong waterproof coating 3 Brush the foundation pit with a concentrated waterproof coating of 1.5kg per square meter 1 Check the foundation pit Check whether there is water seepage in the elevator shaft 2 Repair and plug the defective place with a fast plugging agent or dry strong waterproof material 3 Use 1.2-1.5kg per square meter of concentrated waterproof coating to brush 4 For wet foundation pit and elevator shaft, dry strong waterproof coating can be used for waterproof construction coating The home is focused on coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
