Water expansion sealant construction technology introduction
Water sealant construction technology introduction Water sealant with the continuous progress of science and technology, not only has achieved extensive application in the project, but also achieved good results.
Water-swelling sealing glue is mainly used for the seal of the joints of the structure, leakage of steel bars and pipelines, etc. When the joint is filled with water, it can use the elasticity of the sealing glue and increase the volume to fill the gap, so as to stop the water. Therefore, it has the function of double seal sealing. The reason why waterstop sealant can be widely used in practical engineering is precisely because of its unique performance advantages. Amorphous paste can make it adapt to the irregular base surface of the joint waterproof, and has the characteristics of easy construction and strong operability, in addition to apply to various joints, but also suitable for different materials, small operating space and construction difficulty Sealed water in the upper part. After the water, the volume is 220% of the original volume, and does not sag in the vertical surface construction, and has good durability and chemical properties.
Water sealant has the following performance advantages:
1 good water stop effect. It has a double-sealed water-stop mechanism with rubber-elastic water-stopping and volume-water-stopping after water, and it can withstand 1.5 MPa water pressure.
2 strong durability and low rate of change. The urethane linking chain contained in the FL-606 structure will not be lost during long-term use, and its service life can exceed 100 years at 20°C.
3 construction is convenient. One-component gels can be constructed using caulking glue.
4 construction paste. Whether the base surface is smooth or rough, it can be firmly bonded to the concrete surface.
5 environmental protection. Due to its good chemical resistance, it is an environmentally friendly product.
6 cost-effective. Compared with the construction joint waterproof material has performance.
