Shandong rubber waterstop acid and alkali resistant national standard material 15751651235

Introduction to rubber waterstops
Waterstop rubber is also known as water conservancy engineering seals and sluice rubber seals. It is an indispensable part of hydropower projects, dams, culverts, gates, farmland water conservancy, etc. to prevent water leakage, water seepage, shock absorption, fastening and sealing. Waterproofing is quite good
Our company can produce a variety of products of different models and specifications, made of different materials, chloroprene and other series of products. We warmly welcome users to use our company's water conservancy engineering seal products.
Rubber waterstops are made of natural rubber and various synthetic rubbers as the main raw materials, mixed with various accelerators and fillers, and are molded by plasticizing, mixing and pressing. There are many varieties and specifications, including bridge-shaped and mountain-shaped. type type type type type type type type type type etc. According to the usage, it can be classified into buried rubber waterstop and back-mounted rubber waterstop. Rubber water-stop material has good elasticity, wear resistance, aging resistance and tear resistance, and has strong adaptability to deformation and good waterproof performance. The temperature range is 1°C. It should be noted here that the rubber waterstop must not be used when the temperature exceeds the limit, and when the rubber waterstop is subject to strong oxidation or corrosion by organic solvents such as oil.
Applications of rubber waterstops
Rubber waterstops can be widely used in various types of concrete structures, such as retaining dams, reservoirs, subway culverts, tunnels and other underground projects. In some construction projects, due to the inability to pour continuously, the deformation of the foundation, or the thermal expansion and contraction of concrete components caused by temperature changes, etc., deformation joints are often left during pouring, and these deformation joints are construction joints. Often results in structural leaks. In order to prevent leakage caused by deformation joints and construction joints, it is required to use rubber waterstops at the deformation joints or construction joints. This is because the rubber water-stop bag can not only prevent groundwater or external water from leaking into the building structure, but also prevent water inside the building from leaking to the outside world. Based on this, rubber water-stop bags are widely used in underground concrete expansion joints such as sewage treatment plants, water plants, dams and hydropower stations. During the construction process, the rubber waterstop is embedded in the deformation joints when pouring concrete and is integrated with the concrete. The plug-like plug can effectively prevent water seepage and leakage at the deformation joints of the structure, and play a role in shock absorption and buffering. This ensures that the waterproofing requirements in engineering structures are met.
