(A) the selection of materials and their properties rubber factory clearance being rubber hose during use is subject to external forces and prolonged contact with a variety of soil, water. Therefore, the requirements of a rubber material must have excellent flexibility, compression, high tensile strength, elongation, and wear and tear of high performance, wide temperature range. Some products also requires alkali-resistant garden, salts and other inorganic and resistance to various mineral oils, animal and vegetable oil, used in underground engineering must also have some anti-Xia performance. - Like a big rubber commonly used natural rubber, styrene-butadiene rubber, chloroprene rubber, EPDM rubber, rubber properties in a variety of different, and therefore selection of different rubber material according to different requirements. Domestic products using natural rubber and butyl rubber more nitrogen, in actual use have achieved a good sealing effect. Germany using SBR more. At home and abroad has gradually push / use anti-aging properties excellent resistance to high and low temperature water for a long time and compressive deformation smaller EPR. Water swelling rubber water-stop is imported special rubber as the main raw material, with inorganic absorbent materials, more than ten kinds of high-viscosity resin special material by mixing, kneading, extrusion products made of a rubber water stop.
