(1) Rubber Sealing rubber water-stop is the use of rubber high elasticity and compression deformation characteristics of elastic deformation under various loads, and thus play an effective fastening seal to prevent leakage of the building structure, water seepage and reduce shock buffer. In the architectural design generally larger projects, because not continuous casting, or by ground deformation, or due to thermal expansion and contraction of concrete structures caused by temperature changes and other factors, the need to leave the construction joints, settlement and Deformation in these joints It must be installed to bring water management to prevent water leakage problems. When the rubber is mainly used for water stop situ concrete construction joints and deformation joints and concrete structure has become one of the basic engineering, such as underground facilities, tunnels, culverts, water aqueducts, dams, reservoir and other structures. Sealing is the use of rubber high elasticity and compression deformation characteristics of elastic deformation under various loads, and thus play an effective fastening seal to prevent leakage of the building structure, water seepage and shock absorption cushioning effect. Foundation engineering, such as underground facilities, tunnels, culverts, water aqueducts, the architectural design generally larger projects, because not continuous casting, or by ground deformation, or due to thermal expansion and contraction of concrete structures caused by temperature changes and other reasons, need left construction joints, settlement and Deformation in these joints must be installed to prevent flood water caused leakage. Sealing located mainly in the construction joints and deformation crack when used in situ concrete and concrete structure has become one of the basic engineering, such as underground facilities, tunnels, culverts, water aqueducts, dams, reservoir and other structures. China Rubber Reuters "Last year, I visited a number of enterprises, the development of rubber industry in-depth study, but also to touch the pulse of China's rubber industry. I deeply feel, Chinese rubber industrial powers made major progress , intelligent manufacturing, electricity providers and capital operation of the three new development model by the industry attention, but also for promoting rubber industry to upgrade their effective Pushing Hands. "January 21, China Rubber Industry Association, Fan Rende, honorary president of the Rubber Association says an interview with reporters China Rubber Net held its 33rd meeting on the Secretary-General.
