Supply of water swelling rubber seal type Rubber Sealing P 651 Rubber Sealing

New River County Water Machinery Plant Wanyuan one, BW-96-type water expansion of the seal by the polymer swelling material and rubber mixing together, is a new building waterproof material only after the water swelling can squeeze close the gap between the old and new concrete, forming an impermeable plasticity colloids, in order to solve the leakage problem of concrete construction joints, fill the blank stop waterproof material. Two, BW-96-type water expansion of the seal has the following salient features: a, selection of anti-aging, excellent water resistance chlorobutyl rubber as the main material, combined with its specific material, a reliable durability ; b, self-adhesive, it can rely on their own adhesive force overlap; c, using a special process of the inorganic and organic water-absorbent closely integrated with other materials; d, has excellent plasticity, users can request for product ; e, non-toxic materials, does not contain any heavy metal salts and toxic substances, does not pollute the environment; f, the expansion ratio can be adjusted according to user requirements. Three, BW-96-type water expansion of the seal has a notable feature: a, water swelling properties. When there is water infiltration has laid the seal gap, it will swell, blocking water seepage cracks, seepage channel cut off to prevent leakage, seepage good effect. b, the overall expansion is good, does not disintegrate, anti-erosion, compression good rebound, the slow pace of expansion, expansion potential, anti-pressure ability, impedance ≥2.5Mpa. c, can be used for construction of water wealth of engineering and construction projects during the rainy season, the main material for the inorganic mineral material, anti-aging, corrosion resistance, impermeability effect from alternating temperature change, a reliable durability. d, simple and non-sticky, install and use, and affordable. Fourth, the scope and conditions: BW-96 water expansion of the seal is suitable for concrete construction joints, seams after pouring on the interface, the second pouring concrete, to water expansion gap completely blocked seepage, water stop and replace the traditional steel rubber water stop. Widely used in storage tanks, sedimentation tanks, basements, underground garages, subways, tunnels, culverts, levees and other underground construction and water conservancy projects. The seal must be in order to play a role in plugging impermeability substantially enclosed constraints. Five. Use; a, in-situ concrete construction joints: the construction of the concrete surface has been cutting hair, the seal release paper removed, placed in the middle along the longitudinal width of construction joints and give pressure to make it closely, every 50cm ride up and down the adhesive stick interface overlapping and compacted concrete nails peg. b, concrete crack: the crack width of each groove hewn 4cm will seal embedded in the seam, pressing the bottom groove depth accounted for 1/3 of the remaining portion of the trench with cement mortar smooth, then the polymer cement paint twice. VI Notes: a, paste interface should be kept dry. It shall not apply to seal cracks inside exposed. b, sealing of construction joints and paste interface to close, construction joints along the direction of extension shall not stay off dust and other scum can not be overridden. c, is concrete to fully seal package, package thickness> 5cm. d, before pouring the next concrete to seal fixed later, should avoid being soaked by rain or construction of water. When e, seal storage and transport, avoid moisture and extrusion, stacking should not exceed four. f, when concrete vibrators, vibrators should avoid touching the seal.
