Waterproof materials related to the raw materials which ah
④ metal waterproof material. Thin steel plate, galvanized steel plate, pressure plate, coated steel plate can be directly used as roof panels, for waterproof. A sheet of metal used in a basement or underground structure. Thin copper plate, thin aluminum plate, stainless steel plate can be made of structural deformation of the sealing water zone. Metal waterproof layer of the connection to be welded, and brushing rust protection paint.
③ cement waterproof material. Adhesives, such as water repellents, aerators and expansives, can enhance the hydrophobicity and impermeability of cement mortar and concrete. The cement and sodium silicate Mortar, can be used for underground engineering plugging waterproof.
Waterproof material variety, according to its main raw material is divided into four categories:① asphalt waterproof material. Asphalt asphalt, asphalt and coal asphalt as the main raw material, made of asphalt linoleum, paper asphalt asphalt, solvent and water emulsion asphalt or asphalt rubber coatings, ointment, with good adhesion, Water resistance, corrosion resistance and durability.
Waterproof materials involved in the raw materials are:
Asphalt waterproofing membrane main raw materials are: asphalt, sbs, apao, oil (oil three-line oil, rubber powder, recycled propylene, talc and so on.
The main raw material of polymer waterproofing membrane is some olefins.
The structure of the building to prevent the rain, snow and groundwater penetration; to prevent the air of moisture, steam and other harmful gases and liquid erosion; separation structure to prevent the infiltration of water supply and drainage. These impermeable, leaking and eroded materials are collectively referred to as waterproof materials.
② rubber and plastic waterproof material. Polybutylene rubber, butyl rubber, polyvinyl chloride, polyisobutylene and polyurethane and other raw materials, can be made of flexible tireless waterproofing membrane, waterproof film, waterproof coating, coating materials and ointment, clay , Sealing tape and other sealing materials, with high tensile strength, elasticity and elongation, adhesion, water resistance and weather resistance and other characteristics, can be cold, long life.
