Rubber Sealing can be widely used in various types of concrete structure, for example: underground engineering block dams, reservoirs, subway, culverts, tunnels and the like. In some construction projects, because they can not cast a series, or because the deformation of foundation, or because the temperature changes due to thermal expansion and contraction of concrete structures and other reasons, the cast often left Deformation, construction joints, these joints against leakage Problems should be used and the Deformation of the site must use rubber water-stop way to handle, it can not only prevent water leaking into the groundwater or outside the building construction and avoid water leakage inside the building to the outside world. It is widely used in underground concrete expansion joint sewage treatment plants, water plants, dams, hydropower stations. Selection of national norms of all commodities produced gb18173.2-2000 specification organization, scale Gongyi fulfill all according to national norms, such as users with special needs, according to user requirements and manufacturing. Rubber Sealing model to divide species classification numbers to facilitate the planning and user orders refer. According to user needs the production of various shapes, size rubber water stop, the other can not the same project as the demand is not the same site with the cross-shaped, T-shaped, slope type and table corner type of goods, applicable to Any planning needs. Rubber water stop during transportation, should be protected from direct sunlight, not with heat, oil and hazardous solvents touch. Products should be taken straight flat, do not increase the pressure. Storage places best kept -10- + 30, relative humidity of 40% -80%. Rubber Sealing and sealing rubber-based 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, 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.
