Description of rubber water stop:
Take rubber as the main raw material , mixed with various additives and fillers, vulcanization molding process , according to the usage it could to the usage it could be divided into deformation joints water-stop , construction joints water-stop , steel edge water-stop, according to the setting position it could be divided into amid-bury rubber water-stop back-stick type rubber water-stop.
B type : water stop strip, suitable for easy deformation joint
S type : water stop strip suitable for construction joint
J type: water stop strip suitable for joint which request anti-aging.
Property of rubber water stop:
Elastic deformation happens under high load pressure for the rubber high elasticity, therefore it can prevent leakage effiviently, fasten sealing, also reduce shaking as a result, it can ensure the buildings' lifetime . good flexibility, abrasion resistance, aging resistance and tear resistance, strong ability to adapt to deformation , good waterproof performance, temperature ranges from -45 centigrade to +60 centigrade.
Application of rubber water stop:
Widely used in concrete struction , such as : dams, reservoirs, underground ,culverts, tunnels and other underground projects.
