The expansion of water use
(1) products using very simple rubber water swelling, with all kinds of engineering pipe and wall pipe bolt size can be any combination of seal.
(2) rubber strip and with hpz, combined water swellable rubber waterstop. Phase can completely solve the rubber sealing strip and concrete structures around the penetration problem.
(3) the rubber strip can be used for the underground pipeline plugging water swelling, the water rubber multi-purpose expansion sealing belt, tight winding in the cracks or leaks. Then use the concrete seal, other methods can also be sealed.
Working principle of water expansion rubber strip
In all kinds of underground construction engineering, hydraulic engineering, tunnel engineering, municipal water supply and drainage engineering, water pool, swimming pool, building a large number of applications to pull the bolt, and various wall pipe water pipes in hardened concrete, it is easy to form a small gap, but also on the formation of the leakage passage in the present construction is the plate in the middle 2mm method of thick annular sealing ring welding, to extend the low permeability seepage water, but also often have leakage phenomenon. The building water is generally not waterproof measures, resulting in a layer of water, the lower the dripping phenomenon.
Excellent waterproof seal
Such as the use of water swellable rubber, when water seeping into the end, can rely on their own water swelling pressure, compaction of concrete structures, and the pipeline of the bolt gap, blocking the leakage passage, to achieve permanent waterproof effect.
Water swellable rubber is a kind of waterproof material excellent in the majority of members of the design and construction of support and recommendation, over the years, since the waterproof structure of the underground engineering of the reinforced concrete material has been widely used in various categories, its good flexibility, extensibility and expansion of water has been renowned throughout the country. The water resistance of the material with excellent resistance to chemical durability and weather resistance has been the night service of underground shopping malls, underground garage, underground water diversion project, open caisson, confirmed by the flood wall and many other projects.
