2. Purpose The water-swellable rubber strip product is extremely easy to use and can be sealed in any combination according to the size of various pipes and wall pipe bolts in the project. The water-swellable rubber strip can be combined with the rubber waterstop to form a water-swellable rubber waterstop. It can completely solve the problem of seepage between rubber waterstops and concrete structures. Water-swellable rubber strips can be used to plug leaks in underground pipelines. The water-swellable rubber multi-purpose sealing tape is tightly wrapped around cracks or leakage points. It is then sealed with concrete or other methods.
3. The working principle of rubber strips that expand when exposed to water. Pull bolts, various wall pipes and upper and lower pipes are widely used in various underground construction projects, water conservancy projects, tunnel projects, municipal water supply and drainage projects, reservoirs, swimming pools, and buildings. When water pipes are solidified and hardened during concrete pouring, it is easy to form tiny gaps, which form leakage channels. Currently, in construction, we use the method of welding steel plates with thick annular water-stop rings in the middle to extend the water seepage line and increase the anti-seepage capability. However, there are often Leakage occurs. There are generally no waterproofing measures for the upper and lower water in buildings, so there is water dripping from the upper layer to the lower layer. For example, when water-swellable rubber strips are used at one end, when water seeps in, they can expand with water and use their own pressure to squeeze the gap between the concrete structure and the pipe pull bolt to block the water seepage channel to achieve the effect of permanent water-proof and anti-seepage.
Water-swelling rubber is an excellent waterproof material. With the support and recommendation of the vast number of designers and construction personnel, this material has been widely used in underground projects of various types of reinforced concrete self-waterproof structures for many years. Its excellent elasticity, extensibility and expansion water-stopping properties have become well-known throughout the country. The material's superior water resistance, chemical resistance, durability and weather resistance have been proven by its day and night service in underground shopping malls, underground garages, underground water diversion projects, caissons, flood control walls and other projects. Water-swellable rubber is a special material with water-swelling function made by mixing hydrophilic polyurethane material and rubber. When soaked in water, there are a large number of hydrophilic groups (-) in polyurethane. This group can be combined with a large number of water molecules through hydrogen bonds, which weakens the force between polymer molecules and causes the rubber volume to increase. Due to the role of hydrogen bonds, water molecules are firmly pulled together. Even under mechanical compression, the water will not be squeezed out. However, this water expansion is reversible. When the water swells, the rubber is in a dry state and the water evaporates. The size can be reduced and the original shape and function can be completely restored.
