BW water expansion rubber seal

BW expansion rubber seal with imported special rubber water, inorganic absorbent material, high viscosity resin and so on more than ten kinds of materials by mixing, mixing, extrusion to form, it is a section developed on the foundation of foreign product is a square shaped strip self-adhesive water expansion type seal.

Relying on its own preset viscous paste in concrete construction joints, after pouring joint interface, the two time after pouring the concrete (i.e. concrete wrapped state). The rubber seal of water will gradually swell in water, a capillary pore blockage may exist, on the other hand, the concrete the interface contact more closely, resulting in high water pressure resistance, the formation of impermeable plastic colloid, the product has a high inflation rate, mobile added strong in construction joints, after pouring with strong balance of self-healing function of joints, self sealing for settlement and the emergence of a new small gap, for the completion of the project, such as gap leakageWater availability, water swelling rubber water stop re plugging, using the seal of low cost and simple construction process, corrosion resistance is the best.

The products in Beijing in June 1988 by the Ministry of science and technology achievements appraisal, won the 1991 National Award, in order to solve the concrete construction joints, pouring seam leakage problems and create a new way to fill a gap in waterproof materials in China。 The quality of the products has reached the world advanced level。 The technology transfer of our company after several years by more the strict theoretical analysis, scientific experiments and solicit suggestions of users, we have developed BW- type, BW- type, BW- type, BW- (slow expansion) type IV (slow expansion seal), formed to adapt to different engineering conditions to perfect water swelling self-adhesiveThe rubber sealing strip。
