Rubber Sealing the hole in the center of the device is usually in the construction of the settlement joint water stop at the body, and settlement joint body occurs at the interface is built of local "deformation" interval at the onset of the settlement; this, If the water stop is "flat single dimension", and that the rubber "Yan Shen resistance to deformation" of the same information circular cross section, there is no good; there, the circular cross-section in the section on settlement joint for the double, than the "flat" multi-layer, can play to avoid the "first layer is damaged," still persist after sealing effect. Rubber Sealing Strip is mainly used for waterproofing of underground works, water stop using the high elasticity of rubber and compression deformation, elastic deformation under various loads, and then play a fastening sealed usefully avoid construction member leakage, seepage and shock absorption cushioning effect, in many construction projects, the elasticity of demand between civil engineering, water and soil have a certain structure, and also waterproof and shockproof and other questions, and devices which use rubber water-stop is useful for processing All of the above means doubt. Above expectations of you to assist, Shijiazhuang Great Wall Rubber Company by virtue of professional skills, excellent team as the basis, by virtue of superior goods in the rubber market is intense competition from a won a place, we promise, as You provide the most excellent rubber water stop. Putty-type water swelling rubber seal with bentonite, imported butyl rubber, inorganic absorbent materials, more than ten kinds of high-viscosity resin materials by mixing, kneading, squeezing the system, this product has a rectangular cross section, circular , trapezoidal, all were strip. The water will gradually swell after commodity, on the one hand there may clog pores gap seepage, on the other hand to make it even more closely touch concrete interface, then the pressure generating greater resistance to water to form an impermeable plasticity gel, this product having a high swell ratio, mobile Supplementary strong, placed in construction joints, after pouring seam has a strong balance of self-healing function, you can block their own new small gap due to subsidence and presented. Sealing action of the product is superior to conventional sealing steel, rubber and plastic water stop. Seal with a low cost, simple construction technology, corrosion resistance, no pollution. I plant produced water swelling seal Product quality has reached the international advanced level. June 3, the United Steelworkers (USW) to the US Department of Commerce and US International Trade Commission (ITC) to apply, the demand for passenger and light truck tires from China 's launch anti-dumping and countervailing inquiries and allegations of dumping and downs 60.15%, 25.73% subsidy for the downs. November 24, the US Department of Commerce published the preliminary results of countervailing duty; December 22, and amended the preliminary countervailing duty rates. Both the preliminary tax rate forced the respondent companies were 11.74% and 12.5%, and other companies 12.03%; Shandong Yongsheng Rubber Group Co., Ltd. acquired 81.29 percent punitive tariffs. According to China's customs calculations, China's exports of the United States involved in the delivery of goods is $ 3.337 billion, is by far the tire occupation suffered the largest amount of trade remedies in the first, touching thousands of domestic companies, including 68 production companies, will affect China's tire and occupational nearly one million industrial workers.
