The welding method of composite geomembrane is the welding method of waterproof board

The composite geomembrane is widely used in contemporary anti-seepage geomembrane engineering projects. The common welding method of composite geomembrane is the welding method of waterproof board. What problems should be paid special attention to laser welding waterproof board? The following editor made a concise discussion on this problem. Let's explore it together.
What should be paid attention to when laser welding the waterproof board with composite geomembrane?

1.The waterproof layer in the composite geomembrane is laser welded using a hot-melt monorail welding machine. After the KS glue melts, it should be evenly distributed on the anchoring seam, and the total spacing of the joint seam should not be less than 15cm. Non-proof cloth and non-proof cloth are sewn with a portable sewing machine and bonded with KS adhesives commonly found in composite geomembranes. A common inspection method is to visually inspect whether the two sides of the impermeable membrane material are flat.

2.If the standard value displayed by the barometer is still no problem, it means that laser welding is now in accordance with the regulations of the decoration project. The vertical connector should be separated from the dam foot, and the bent foot should be built on a vertical surface of about 1.50 meters. The orientation of the composite geomembrane should be flat on the line with a large inclination angle, without stretching too tightly, and leave 1.50% of the remaining space for partial stretching.
3.The welding method of the waterproof board is a relatively complicated task of hardware machinery. The waterproof board is neatly regulated during laser welding, and there is no slip laser welding, which is separated from the essence of things. The change in embedding temperature affects the ductility variable.
4.In the case of large sand, the laser welding of the waterproof board cannot be stopped, but the selected precautionary measure is that when the distance of the outgoing lateral laser welding exceeds 50 cm, it should be T-shaped and cannot cross. The laser anchor should be inspected during the laser welding. Inside. When the temperature does not reach 5 ℃ and the temperature of the straw cloth does not reach 5 ℃, the impermeable membrane cannot stop the welding and waterproofing board according to the standard.
The above is the problem of oil slick that should be paid special attention to when laser welding composite geomembrane waterproof board. Normally, when applying local electricity in special cases, if the laser welding and laying tasks of geomembrane waterproof board are to be done well, the corresponding voltage stabilizer must be applied, and the tools must be cleaned before laser welding.
