Description :

　　SuzhouJinwei MachineryManufacturing Co., Ltd. - CRCC certified EVA polymer composite waterproofing membrane equipment

　　Product features: 1. High quality ethylene vinyl acetate copolymer, a thermoplastic with rubber like elasticity, is selected to give the finished product good flexibility. The processing of details such as corners and pipes is quite simple and fast. 2. High tear resistance, good puncture resistance, good waterproof, anti-seepage, and hydrolysis resistance; 3. Special antibacterial agents are added to the material to prevent microbial erosion and extend the product's lifespan; 4. Good resistance to root infiltration, especially suitable for planting roofs; 5. The product has a wide adaptability to adhesives and can bond well with various adhesives; 6. There are no special requirements for the moisture content of the grassroots. As long as there is no visible water, normal construction can be carried out without any impact on the construction quality; 7. Good aging resistance, with a service life of over 50 years when buried underground; 8. Good low-temperature flexibility, able to maintain good flexibility even under low temperature conditions of -30 ℃; 9. The product is completely free, made of green material; Scope of application: Traffic engineering: Waterproof and anti-seepage engineering for tunnels, subways, highways, tunnel bodies, bridges, etc; Construction project: waterproofing and anti-seepage of roofs, basements, etc. Water conservancy engineering: waterproofing and anti-seepage works such as reservoir embankments, cofferdams, and water channels. Engineering: Waterproofing for anti-seepage projects such as garbage disposal sites, sewage treatment plants, metallurgical and chemical plants. Other projects that require waterproof, anti-seepage, and moisture-proof treatment. Preparation work before laying construction method: Requirements for the base layer: Clean the laying surface, ensure that the base is flat, the soil is solid, without unevenness, sharp objects, etc. Waterproof board welding: Joint treatment is a key construction procedure, generally using thermal welding method. The surface of the EVA waterproof board connected is heated to melt it, and then melted into a body through pressure. 1. For the pre laid waterproof board, it is required that there should be no oil stains, moisture, dust, etc. at the edge joints; 2. Before welding, adjust the two edge films at the joint to overlap, with a fixed width and overlap width of 70mm, which is generally flat and free of wrinkles; 3. Use a specialized welding machine for welding.
