Putty type water-swelling water stop ring manufacturer

Manufacturer of putty-type water-swellable water-stop rings
The common names of putty-type water-swellable water-stop rings are water-swellable water-stop rings, water-swellable water-stop rings for pull bolts, and water-stop pieces for pull bolts. Classification: putty type water-swellable water-stop ring and product-type water-swellable water-stop ring Product Features
In the traditional concrete wall formwork support, pull bolts or lath-type tie rods are used to connect the inner and outer two sets of vertical As the main connector of the formwork, the tens of thousands of tension bolts used to fix the steel formwork penetrate the wall throughout their length, thus losing the waterproof function of the waterproof concrete itself. In order to solve this problem, a thick steel water stop plate is welded in the middle of the butt bolt. The disadvantage of this method is that it is difficult to inspect and guarantee the quality of the weld, and it is passive waterproofing. Once there are defects such as cracks, slag inclusions, burning pins, and pores in the weld, subsequent water seepage paths will be formed and difficult to cure.
The putty-type water-swellable water stop ring is made of water-swellable rubber, and its performance reaches the various indicators in Part 3 of "Polymer Waterproof Materials" - Water-Swellable Rubber. It can be a round or rectangular piece. The general specifications of the strong body are outer diameter size and thickness. When in use, just put the water stop sheet tightly on the middle part of the pull bolt or lath type tie rod, and eventually it will be buried in the cast-in-place concrete to achieve the best waterproof effect.
The putty-type water-swelling water stop ring is a new type of waterproof engineering material refined from polymer inorganic water-absorbing swelling materials and rubber. The general specifications of the water-swelling water-stop ring are two types: outer diameter and thickness of one centimeter. The inner diameter can be processed into an inner diameter of , according to the size of the steel bar. When exposed to water, the water-swelling water-stop ring can absorb water and expand at a high expansion rate. It relies on its own expansion to squeeze the gap between the concrete and the tension bolts, and can fully play the role of water-stopping. In actual construction, the operation is very flexible and convenient, and saves money. It saves labor time and raw material costs. It is an updated product of the welded waterstop ring. At present, the concrete formwork tension bolt waterstop ring has been used in various projects.
The putty-type water-swellable water stop ring is made of water-swellable rubber. It can be a round sheet body. The opening in the middle should be used according to whether it is used on the tension bolt or the tension bolt. The different rings are made into round holes or cut out with a long slit running through both sides. The thickness of the water stop ring body is , and the diameter or side length is . The commonly used specifications are the outer diameter, thickness, and middle hole diameter. The rubber ring is smaller than the diameter of the pull bolt. The outer size of the rubber ring is adjusted according to the height of the water head, the thickness of the ring body, or the number of rings used on each bolt. When in use, just put the water stop ring tightly on the middle part of the pull bolt or pull piece, and finally it will be buried in the cast-in-place concrete. When a building is in use, if there is pressure water flowing through the bolt gap on one side due to the shrinkage of the concrete itself, it will inevitably seep into the middle. When it encounters the rubber water stop ring, the water stop ring will absorb water and expand, forming a water-impermeable plastic colloid, blocking it. The surrounding seepage channels act as a water stop.
