Buried in rubber water-stop manufacturer of rubber water stop length

Buried in rubber water-stop rubber water-length manufacturers finally understand that a good sharp knife only good quality is the development of large-scale manufacturers, trustworthy. Rubber Sealing with a domestic natural rubber and synthetic rubber as the main raw material, mixed with various additives and fillers, the mastication, mixing, pressing, many different specifications, a bridge type, Mountain type , P, U-shaped, Z-type A, B, T, H-type, E-type, Q-type, etc., depending on the usage can be classified as buried rubber water stop and backing with rubber water stop. The sealing material has good elasticity, abrasion resistance, aging resistance and tear resistance, adapt to the deformation ability, good water resistance, temperature range of -45 ℃ ~ + 60 ℃. When the temperature exceeds 70 ℃, and When the rubber water stop by strong oxidation or erosion by the oil and other organic solvents, are not allowed to use rubber water stop. Steel side rubber water stop Features section structure using non-uniform thickness, sub-district and waterproof strong area, so that all parts force uniform and reasonable. Telescopic long hole wall is flat, construction formwork system folder contact surface, easy dislocation; additional mounting holes and reinforced steel plate connected to rigid fixation is not easy displacement. Galvanized steel with good adhesion to concrete, so waterproof better. Water swelling water stop use of national standards GB18173.3-2002 standard testing and production of the table as follows: Project Performance requirements PN-150 PN-220 PN-300 volume expansion ratio (%) ≥150 ≥220 ≥300 high temperature flow properties ( 80 ℃ & # 215; 5h) No low temperature flow test (-20 ℃ & # 215; 2h) no embrittlement buried rubber water-stop product use: Buried in rubber water-stop can be widely applied to various types The concrete structure, for example: underground engineering block dams, reservoirs, subway, culverts, tunnels and the like. In some construction projects, because it is not a continuous casting, or due to the deformation of foundation, or due to thermal expansion and contraction of concrete structures caused by temperature changes and other reasons, often leaving the casting deformation joint, construction joints, these joints against leakage Deformation of the issue will be adopted in the use of the site would have to be buried rubber water-stop way to solve, it can prevent water leaking into the groundwater or outside the building structure, the water will also prevent leakage to the outside building .
