How does the waterproofing membrane work?
4, rolling the membrane: the first turn up the end of 1m long, with a long torch melting the bottom of the hot melt adhesive, the rapid paste fixed on the grassroots, and then re-harvest the rest of the volume. The gunmen stood on the paved webs, aligned with the corners of the rolls and the surface of the base layer with the flame of the long gun, and slowly rolled the edges by melting the hot melt. The web is pasted on the base;
3, the ignition: first open the liquefied gas cylinder switch, and then hand gun slowly open the gun switch, to be heard when the gas hissing sound, ignite the flame, and then adjust the switch, the flame was blue. Ignite people should stand behind the nozzle side, so as not to be burned by fire;
2, in accordance with the roof slope in the direction of the parallel roof will be placed in the waterproof membrane, and unwound;
The use of hot-melt method for waterproofing membrane construction, the following steps can be carried out:
1, before the grass-roots clean-up construction, and determine the dryness of grass-roots meet the construction requirements;
5, lap seam treatment: the roll is rolled, the adjacent two webs of the joints with a short stove welding welding sticky, heated to spill hot melt adhesive for the degree, and then use the flame and iron wipe The sub-joints will be evenly heated to wipe the edge;
6, the coil side of the sealing side of the construction.
