China Water Swelling Rubber Water Stope Strip

In addition to the ordinary rubber seal with the performance of water, its main feature is the use of water within the water with a special expansion of the rubber made of water. This expansion of the expansion of rubber in the water after the expansion of the waterstuffs and structures to enhance the tightness, so that water, water effect better. Water - swellable rubber water - tightening zone expansion waterproof line part of the implementation of rubber GB18173.3-2002 standard. The rest of the rubber and ordinary rubber water stop with the same physical and mechanical properties, the implementation of GB18173.2-2000 standard. Physical properties of water - swellable rubber (standard GB / T18173.3-2002).
In order to make the water-bearing parts of the force evenly and rationally, our company developed and designed the RDZ series of water-swellable rubber waterstops, starting section with a non-equal thickness structure, divided into strong zone, waterproof area and installation area, at the same time The outer wall of the telescopic hole is flat. When the template is clamped, the contact surface is large and the dislocation is prevented. The mounting hole is added in the installation area, which can be fixed with the adjacent anchor bar, and it is not easy to be installed.
