Guangxi rubber water stop, rubber water stop Nanning and Baise rubber water stop, rubber water stop Wuzhou, Liuzhou Rubber Sealing price, Qinzhou rubber water stop, rubber water-specification Fangchenggang seal is made of a polymer inorganic swelling material and rubber mixing together for a variety of underground construction and build engineering, hydraulic engineering, transportation engineering, power plant cooling towers, municipal water supply and drainage masonry concrete construction joints to prevent leakage of material 1 Introduction RC Templates bolt holes and construction joints to outdoor wall is hidden parts of the main building leakage, the use of processed BW seal. [1] PN (BW) seal is made of a polymer, an inorganic water-swellable material and synthetic rubber and additives having a new building capable of self-adhesive waterproof material. Water absorbs water volume expansion, crowded close the gap between the old and new concrete, forming an impermeable plasticity colloids. The product in June 1988 in Beijing through ministerial-level appraisal, won the 1991 Technology Achievement Award, and awarded a certificate to become nationally recognized qualified products. The product is to solve the problem of leakage of concrete cracks opened up new roads, to fill a gap in our waterproof. Product quality has reached the world advanced level. Product performance of the product ash black putty-like gel, has good resistance to weather, aging well, seepage stanch, corrosion-resistant, easy to operate, and low cost. The main purpose of PN (BW) seal is constructed of a variety of underground construction engineering, hydraulic engineering, traffic engineering, power plant cooling towers, municipal water supply and drainage of reinforced concrete construction joints seepage stanch the latest and best materials , completely solve the water stop rubber and steel is easy to produce by friction around the seepage problem. Seal product features of this product has expanded flooding, "water seal" effect; with the expansion slow, soaking 186h its expansion rate ≤ 50% maximum rate of expansion; convenient installation and construction of the product, low price, and no toxic pollution, no solute precipitates in a long time under water immersion; and other hydrophilic swelling water stop compared to the biggest difference is its hydrophilic swelling after long repeated expansion still not lost. Quality standards a. Water swelling rubber surface should be clean, flat, no scratches, bubbles and other impurities, neat edge. b. Tensile strength (Mpa) ≥3.5c. Elongation at break (%) ≥350 e. hardness (Shore A) (degrees) 40 ± 3f. hydrostatic expansion% ≥200g. [2]
