Application and function of rubber waterstop in engineering waterstop uses the high elasticity and compression deformation of rubber to produce compression elastic tensile deformation under various loads. It is mainly used on the permanent joints and peripheral joints of underground foundation and tunnel engineering to tighten and seal, prevent water seepage and leakage, and ensure the service life of engineering buildings. In some underground projects, rubber Waterstops use the high elasticity and compression deformation of rubber to produce elastic deformation under various loads, so as to tighten and seal, effectively prevent water leakage and seepage of building components, and play the role of shock absorption and cushioning. In many engineering buildings, there are certain expansion requirements between civil engineering and water and soil structures, as well as waterproof and shockproof problems, Therefore, the use and installation of rubber Waterstops is an effective means to solve the above problems. It is mainly used in permanent deformation joints that must be set during concrete cast-in-place, such as canals, tunnel outlets, retaining dams, water conveyance aqueducts, etc

water swelling rubber waterstop is a new product recently developed by the company. This product is a hydrophilic swelling polymer added to the rubber, which has the properties of general rubber products and the unique property of self expansion in case of water. It is a new waterproof material, which can stop water with water, and the waterproof effect is more reliable than that of general rubber. The water swelling rubber waterstop has more excellent characteristics and advantages: this kind of waterstop product will produce 2-3 times of expansion deformation after encountering water or moisture, and fill all irregular surfaces, cavities and gaps of the joint, while generating huge contact pressure to completely prevent water leakage. When the joint or construction joint displaces, causing the gap to exceed the elastic range of the material, the ordinary rubber water stop material will lose its water stop function, and the material can also stop water by absorbing water and expanding. Using water swelling rubber as the plugging and sealing material can not only save the consumption, but also eliminate the elastic fatigue caused by excessive compression of general elastic materials, making the waterproof effect more reliable. Water swelling rubber waterstop not only has good adhesion and low temperature resistance of general putty, but also has good expansion characteristics. The product is synthesized from a variety of polymer chemical materials, with higher strength than ordinary putty, and is especially suitable for waterproof engineering

the quantities are generally calculated according to the length of each specification. There are many sales forms of back-up rubber Waterstops, but few can directly find manufacturers, and we are the most direct product manufacturers related to back-up rubber Waterstops. Our products about back stick rubber Waterstops have many styles and affordable prices. Welcome to consult our customers. We have been doing back stick rubber Waterstops for many years, which is your best choice. Rubber waterstop and waterstop rubber are made of natural rubber and various synthetic rubber as the main raw materials, mixed with various additives and fillers. After plastic refining, mixing and pressing, they have many varieties and specifications, including bridge type, mountain type, P type, U type, Z type, B type, T type, H type, E type, Q type, etc. According to the use situation, it can be classified into middle buried rubber waterstop and back attached rubber waterstop. The water stop material has good elasticity, wear resistance, aging resistance and tear resistance, strong adaptability to deformation, good waterproof performance, and the temperature range of use is -45 ℃ - +60 ℃ Rubber Waterstops shall not be used when the temperature exceeds 70 ℃ and the rubber Waterstops are subject to strong oxidation or erosion by organic solvents such as oil

rubber waterstop uses the high elasticity and compression deformation of rubber to produce compression elastic tensile deformation under various loads. It is mainly used on the permanent joints and peripheral joints of underground foundation and tunnel engineering to tighten and seal, prevent water seepage and leakage, and ensure the service life of engineering buildings. The waterstop uses the characteristics of rubber with high elasticity and compression deformation to produce elastic deformation under various pressures to tighten and seal, so as to effectively prevent water leakage of building structures and play the role of shock absorption and cushioning. In many projects such as construction, water conservancy and bridges, there are certain requirements for expansion, waterproof and shockproof, and the use of back attached Waterstops effectively meets the above requirements

for example, the cross section of the rubber waterstop with steel edge adopts non equal thickness structure, which is divided into strength area and waterproof area, so that the stress on each part is uniform and reasonable. The long wall of the expansion hole is flat, and the steel edge rubber waterstop has a large clamping contact surface during construction, which is not easy to dislocation; The steel plate is added with installation holes to connect with the reinforcement, which is firmly fixed and not easy to move. The good adhesion between galvanized steel plate and concrete, and the rubber waterstop at the steel edge make the waterproof performance better

rubber Waterstops can be widely used in tunnel culverts, water conveyance aqueducts, retaining dams, underground structures, water storage tanks, swimming pools, roofs and other projects... Mainly used (VI). This kind of waterstop product is mainly used for foundation works, underground facilities, tunnel culverts, water conveyance aqueducts, retaining dams, building expansion devices, etc., which are set in the construction joints during concrete pouring, and are integrated with concrete. Ensure the service life of the project construction. 2: Reference of main physical performance indexes of products: refer to cb18173.2-2000 standard 1: hardness: (Shore A) 60 degrees ± 5.2: tensile strength mpa:j ≥ 10 S≥12.
