Description

The hot melt gasket is a kind of hot melt gasket (ring) for tunnel waterproof board made of polyethylene with high injection molding. The product is mainly used in water conservancy, railway, highway tunnel waterproof roll material installation and fixed use of engineering projects. The hot melt gasket is made of high injection polyethylene and special mold with certain specifications for tunnel waterproof board. The product is mainly used in water conservancy, railway, highway tunnel waterproof roll material installation and fixed use of engineering projects. Hot-melt gaskets are mainly used to weld waterproof plates in highway and railway tunnels. The company's product features strong adaptability, flexible raw material mix ratio, can cooperate with the major waterproof board manufacturers to produce various models of waterproof board.Installation: Hot melt gasket installation should be arranged in the shape of a plum. The vertical spacing should be no more than **0cm, each waterproof board in the horizontal direction should be no less than five, and the vertical and horizontal spacing of the tunnel top should be no more than *0cm. (Each square uses 5 hot melt gaskets). When installing hot-melt gaskets, use nail gun to arrange the hot-melt gaskets vertically and horizontally in order to fix geotextile on the excavation surface of the tunnel. Hammer flat the steel nail tail if there is a bulge, so as to ensure that there is no bulge steel nail will puncture the waterproof board.
