What is the classification of waterproofing materials and where are they used?
Waterproof coiled material is made of one or several composite materials of fiber felt, fiber cloth, metal foil, plastic film, textiles and other materials. It is based on dip-coating petroleum asphalt, coal asphalt and polymer modified asphalt, or synthetic polymer materials. Additives and fillers are added and processed by various methods, and then supplied in long strips. Its main function is to play the role of roof waterproofing. Waterproofing materials can be divided into SBS waterproofing materials, APP modified asphalt waterproofing materials, polyethylene polypropylene waterproofing materials, PVC waterproofing materials, TPO waterproofing materials, self-adhesive waterproofing materials, etc.
1.SBS waterproofing membrane
SBS waterproofing membrane and APP modified asphalt waterproofing membrane have the characteristics of strong impermeability, high tensile strength, high elongation, good high and low temperature resistance and convenient construction. They are suitable for waterproofing of roofs and underground of industrial and civil buildings, as well as waterproofing of bridges, parking lots, swimming pools, tunnels and other buildings.
2. Polyethylene polypropylene waterproofing membrane
Polyethylene and waterproofing membrane have the characteristics of high tensile strength, impermeability, low temperature flexibility, low linear expansion coefficient, easy bonding, high friction coefficient, uniform roughness, etc., and can be directly bonded with cement materials in the curing process. They are commonly used in waterproof, anti-seepage, moisture-proof and air-proof projects of various building structures, such as roofs, walls, toilets, basements, cold storage, bridges, pools and underground pipelines.
3. PVC waterproofing membrane, TPO waterproofing membrane
PVC waterproofing membrane is a kind of polymer waterproofing membrane with excellent performance, which has the characteristics of high tensile strength, high elongation, small shrinkage, good flexibility at low temperature and long service life. The product has stable performance, reliable quality and convenient construction, and is widely used in various industrial and civil buildings, subways, tunnels, water conservancy, landfills, chemical engineering, metallurgy and other fields for waterproofing, seepage control and anticorrosion.
TPO waterproofing membrane has the characteristics of strong ultraviolet resistance, natural aging resistance, excellent puncture resistance, high tear strength and high elongation at break, etc. It is mainly suitable for various roofing waterproofing works of industrial, civil and public buildings.
4. Self-adhesive waterproofing membrane
Self-adhesive waterproofing membrane has the characteristics of high bonding rate, high strength, strong extensibility, good self-healing, cold construction, simple construction and high safety. It is widely used for waterproofing of indoor, roof, basement, reservoir, swimming pool and subway tunnel of industrial and civil buildings, and is suitable for waterproofing of roofs with special structures such as wooden and metal structures.
