Product Description

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.
