Do you know that waterproof materials are classified like this?
There is no uniform division of the classification of waterproof materials, because "classification" is a biological behavior, other disciplines are based on biological practices, and most disciplines do not classify the categories as clearly as biology. The same is true for waterproof materials, and strictly speaking, he cannot classify them. Due to the complete system of waterproof materials, there is a classification crossover and non-uniformity. The current classification is only to let the "people" look at it, and has no academic value. Such as large categories of coils, coatings, rigid materials, etc., and then the coil or coating is divided into asphalt, modified asphalt, synthetic polymers, and then the coating is divided into volatile curing, reaction curing . "Roll" is the appearance of the material, "synthetic polymer" is the material property, and "reaction curing" is the film formation method. The same material is not on the "one line" from beginning to end.
Jiuzheng Building Materials Network classifies waterproof materials as much as possible according to the normal habits of everyone. For the above reasons, this classification method is not too scientific, and may be incomplete or wrong.
At present, waterproof materials are mainly divided into two categories:
First, flexible waterproof materials, such as: material coils, JS composite materials, polyurethane waterproof materials, waterproof rubber and other emulsion polymer waterproof materials. These materials are mainly wrapped around the base surface to prevent water from seeping and infiltrating. These materials have a certain elongation and tensile strength. The only drawback is that these materials have a certain degree of waterproofing, which is the waterproof life. These materials are widely used on the base surfaces of roofing, toilets, expansion joints, water floors, masonry, etc.
Second, just raw waterproof material: As the name suggests, it has high strength, but he lacks elongation and tensile strength, but the waterproof life is long after construction, like concrete, such as: water does not leak, cement based penetration crystallization, penetration waterproofing agent, permanent condensation Liquid and so on. They use the porous structure of the concrete structure to pass through the capillary, and use the hydrophilicity to penetrate into the concrete with water as a carrier, chemical reaction occurs, crystals are formed, the capillary pores are waterproofed, and the strength of the concrete is increased. These materials are widely used. It can be used directly in drinking water pools, etc. in basements, toilets, cesspools, and reservoirs. Therefore, in general, buildings with high waterproof requirements are designed with a rigid and flexible waterproof solution!
