What are the characteristics of waterproof board / waterproof board waterproof board is what are the advantages of an impermeable material polymer as the basic raw material, both to prevent fluid leakage, but also can prevent gas evaporation. In construction, transportation, subways, tunnels, widely used in construction. Characteristic strength waterproof board - the same weight under the specifications of each other were higher than the tensile strength of the non-woven needle. UV light - with high UV resistance. Resistance to extreme temperature performance - high temperature of 230 ℃, the high temperature will remain intact and original physical properties of the structure. Permeability and surface drainage - The water board is thick and needle shaped, with good drainage and vertical plane permeability, can maintain this performance after many years. Creep resistance - waterproof board creep resistance than other geotextiles, so long-term good. It is resistant to common chemicals in soil erosion and corrosion of gasoline, diesel and other. Ductility - have a good waterproof board certain elongation under stress, so that it can adapt to uneven irregular base. Feature waterproof board's decision that it has four characteristics: 1, excellent flexibility, barrier properties, elongation and wear resistance; 2, with better isolation, puncture resistance; 3, no chemical pollution; 4 , acid and a variety of chemicals, good dimensional stability, good adhesion, ease of construction.
