The product-type water-swelling water-stop strip is also called the product-type water-swelling water-stop strip. It is a new type of waterproof material that has the performance of general rubber products and the ability to self-swell when exposed to water. The water-stopping and waterproofing effect is more reliable than ordinary rubber water-stopping strips.
Our company's local product-type water-swellable water-stop strips have the following characteristics:
When the rubber comes into contact with water, it will expand and deform at least - times and fill all the irregular surface cavities of the joints. And the gap simultaneously generates huge contact pressure to completely prevent leakage
. When the attachment joint or construction joint is displaced and the gap exceeds the elastic range of the material, the ordinary rubber water-stopping material will lose its water-stopping effect, but this product can still Stops water by swelling by absorbing water.
Using water-swellable rubber as a leak-proof sealing and water-stopping material not only saves energy, but also eliminates the elastic fatigue caused by excessive compression of general elastic materials, making the waterproofing effect more reliable. It has water resistance, chemical resistance and resistance to Good aging performance.
D. It is mainly used for waterproofing existing joints of buildings using the shield construction method, waterstops for construction joints of deformation joints in buildings, and waterproofing of metal components and concrete prefabricated components.
Putty-type water-swellable rubber water-stop strips are also called putty-type water-swellable rubber water-stop strips. It is a strip sealing material with water-swelling properties made of more than ten kinds of materials through dense scouring, kneading and extrusion.
Putty-type water-swelling waterstop strips have high expansion ratio and strong mobility and supplementation. They are placed behind construction joints and have a strong balance and self-healing function. They can self-block new micro-cracks caused by settlement. For completed projects If there is water leakage in the gap during the project, the water stop strip can be used to re-block the leak. The cost of using this water stop strip is low, the construction process is simple and the corrosion resistance is the best. It is widely used in construction joints, expansion joints and cracks in civil air defense, swimming pools, sewage treatment projects, underground railways, tunnels, culverts, etc. and other concrete projects.
Features of putty-type water-swelling waterstop strips:
, water-swelling to stop water when immersed in water
, slow expansion rate, % of the maximum expansion rate when immersed in water
, convenient construction and price Low cost
, non-toxic and pollution-free
, no dissolved matter will precipitate under long-term immersion in water
, compared with other hydrophilic swelling waterstops, the biggest difference is its hydrophilic swelling property It has not been lost after long-term repeated expansion.
