Waterproof material, rubber powder is divided into several kinds, as well as in the waterproof materials industry what role?
Waterproof material involves raw materials:Asphalt waterproofing membrane main raw materials are: asphalt, SBS, APAO, oil (oil, three wire oil, rubber powder, recycled propylene, talc and so on.).The main raw material of high polymer waterproofing membrane is some alkene.
The structure of the building should be protected from rain, snow and groundwater; to prevent moisture, steam and other harmful gases from flowing into the air, and to prevent the seepage of the water supply and drainage. These anti seepage, seepage and erosion materials are collectively referred to as waterproof materials.
There are many kinds of waterproof materials, and they are divided into 4 kinds according to their main raw materials:Asphalt waterproof material. With natural asphalt, petroleum asphalt and coal tar pitch as main raw material, made of asphalt, asphalt felt paper, solvent and emulsified asphalt or asphalt rubber paint, ointment has good adhesion, plasticity, water resistance, corrosion resistance and durability.Rubber and plastic waterproof material. The chloroprene rubber, butyl rubber, EPDM rubber, polyvinyl chloride, three polyisobutylene and polyurethane raw materials, can be made of elastic tire waterproof materials, waterproof membrane, waterproof coating, coating materials and ointment, plaster, etc. the waterstop sealing materials, with high tensile strength, elasticity and elongation, water resistant adhesive and good weather resistance characteristics, can be used for a long time with the cold.Cement waterproof material. A procoagulant effect of compacting the admixture of cement, such as waterproof agent, air entraining agent and expansion agent, cement mortar and concrete can enhance the hydrophobicity and anti permeability; with cement and sodium silicate as coagulant mortar base material configuration, can be used for underground engineering waterproof plugging.Metal waterproof material. Sheet steel, galvanized steel sheet, profiled steel sheet and coated steel plate can be directly used as roof panels for waterproof purposes. A metal waterproof layer used for a basement or underground structure. The thin copper plate, the thin aluminum plate and the stainless steel plate can be used as the water stopping strip for the deformation joint of the building. The metal waterproof layer shall be welded at the junction and painted with antirust paint.
