Product Description
1, Product introduction
Strap rubber combination of water-stop system is generally scalable rubber and galvanized steel with both sides of the composition of the composite pieces.
This waterstop mainly by the middle of the rubber section in the concrete deformation between the joints were compressed or stretched, and play a sealing sealing effect. In general, the poor adhesion of concrete and rubber, in conventional construction, and because the rubber is a soft elastomer, so that concrete is not easy to be cast in the pouring real, so the joints in the expansion, pull away, Often with rubber water-stop loose and fall off, resulting in higher head pressure will produce leakage. For joints with large deformation joints, the problem is more pronounced. Galvanized steel with rubber combination waterstops, basically can overcome the pure rubber bridge waterstops with these deficiencies. And this combination water stop also has a dual function, that is, on the one hand can extend the way to slow the rate of water seepage, on the other hand, galvanized steel and concrete have good adhesion, the water stop can withstand greater tension And torque, so as to ensure that the rubber water-stop concrete in the scope of the effective deformation will not produce loose and fall off phenomenon, improve the sealing effect.
2, the use of installation
choice of materials and requirements
Strip: use galvanized steel strip
Rubber: usually use natural rubber, neoprene, EPDM rubber.
It is required that the rubber and the steel strip be effectively bonded, and the bond strength (peeling strength) between them should be 80 to 10 N / 2.5 mm, so that they are not pulled out under the circumstance of change of external conditions.
Construction and installation
Usually there is no process hole on the edge of the steel strip. When the concrete is installed, the water-stop belt and the steel strip are fixed with the thin iron wire to ensure the pouring and compacting, so that the galvanized steel sheet and the concrete are effectively and firmly adhered.

The company's advanced technology, well-equipped, product quality to the national standard, and has passed the ISO9001 quality system and ISO14001 national environmental system certification, the production of rubber Zhishui Dai, PN (BW) -CL water- PZ-CL water expansion seal, PG-321CL two-component polysulfide sealant, GB caulking sealant, EPDM sponge tape, sealing tape, rubber pumping pipe, foam board, waterproof material and All kinds of rubber and miscellaneous goods, such as complete specifications, good quality, widely used in water conservancy, construction, air defense, subway, bridges, tunnels, highways and other key national projects.

The product of expansive water called PZ standard water expandable sealing water. It is a new type of waterproof material, which has the performance of the general rubber products, and has the water to expand its own performance. Waterproof, waterproof effect than ordinary rubber seal is more reliable.
My company produces products type of expansive water has the characteristics of water:
A, in the case of water will produce less 2-5 times the expansion deformation, and full of all the irregular surface of the irregular surface, hole and gap, while a huge contact pressure, to prevent leakage;
B, when the rigid joint and construction joint displacement occurs, resulting in the gap caused by the gap beyond the elastic range of the material, ordinary rubber sealing material lost the sealing effect, and the product can also through water swelling to seal.
C, the use of water swellable rubber as sealing sealing sealing material, not only the amount of energy, but also can eliminate general elastic material due to too large compression caused by the characteristics of elastic fatigue, waterproof effect is more reliable, water resistance, resistance to chemical properties and aging resistant performance is good.
D, it is mainly applied to the shield construction method now masonry joint water-proof, building distortion seam, construction joints with sealing strip and a metal component, precast concrete ground waterproofing.
