1、 Product Introduction
Water swelling rubber waterstop It is made of * * * inorganic water absorbing expansion material and rubber It is also a new building waterproof material. When encountering water, it can absorb water and expand, with an expansion rate of 250% - 550% times (adjustable), and compact the gap between new and old concrete to form an impermeable plastic gel. In addition to the full performance of the waterstop, it is also made of special rubber with internal waterproof line and water swelling engineering. In this way, the tightness of the waterstop and the structure is enhanced after the expanded rubber expands when encountering water, so that the waterproof and waterstop effects are better.
2、 Performance characteristics
In addition to the performance of ordinary rubber waterstop, the water swelling rubber waterstop is mainly characterized by that the internal waterproof line is made of special rubber with water swelling engineering. In this way, the tightness of the waterstop and the structure is enhanced after the expanded rubber expands when encountering water, so that the waterproof and waterstop effects are better. The part of sealant in the expansion waterproof line shall comply with GB18173.3-2002 standard. The physical and mechanical properties of other rubbers are the same as those of ordinary rubber waterstops, and the GB18173.2-2000 standard is implemented. Physical properties of rubber compound (executive standard GB/T18173.3-2002)
The water swelling rubber waterstop increases the tightness between the waterstop and the structure after the water swelling, thus improving the waterproof performance of the waterstop. Therefore, the water swelling rubber waterstop solves the surrounding leakage problem that has puzzled people for a long time. This product has been widely used in more than 360 * * * projects, with good use effect. This product is mainly used for setting Construction joint And foundation works integrated with concrete structures in deformation joints, such as underground facilities, tunnel culverts, water conveyance aqueducts, water retaining dams, liquid storage structures, etc. Rubber waterstops need to be used together with two-component polysulfide building waterproof sealant. It uses the characteristics of high elasticity and compression deformation of rubber to produce elastic deformation under various loads, so as to play the role of * * * fastening and sealing, preventing water leakage, seepage and shock absorption and buffering of building structures.
3、 Scope of application
The water swelling rubber waterstop can be used in the concrete construction joints of underground buildings. * * * and * * * can solve the problem of water leakage in the construction joints. It is a substitute for the rubber waterstop. Widely used in basements, caverns, mines, bridges, tunnels, subways, sewage treatment plants, dams, reservoirs and other projects. This product not only has all the properties of rubber waterstop, but also specially adopts the internal waterproof line It is made of special rubber for water swelling engineering. In this way, the tightness of the waterstop and the structure is enhanced after the expanded rubber expands when encountering water, so that the waterproof and waterstop effects are better. Therefore, the surrounding leakage problem that has puzzled people for a long time is solved. This product has been widely used in more than 250 * * * projects, with good use effect.
