1、If you buy a composite geomembrane for special welding, please inform the manufacturer in advance that the edge flicking process is urgently needed, that is, when the geotextile and the geomembrane are hot melt bonded, two edges will be stored after being rolled. About 15-20 cm without adhesion is enough. If the ground-breaking site is large, the west-end edge flicking process is urgently needed, and it can only be settled with the manufacturer before placing an order.
2、Similar to super-large projects, the permeation experiment of composite geomembrane uses hot welding method, which is comparable to Haoshengsheng. Even if the edge of the hot welding door is retained, the outer surface is heated and sold by a hot melt welding machine, so that the large surface is returned to the furnace, and then it is fused into a tight seal through downforce.
3、Top paving: The composite geomembrane is laid in one direction, leaving parts of the throwing edge on both sides of the composite geomembrane. When barricading, the direction of each roll of composite geomembrane should be adjusted to facilitate the favorable welding of the two rolls of composite geomembrane together.
4、After the composite geomembrane barricade, as long as there is bad weather, it is necessary to press some edges with sand bags to prevent them from blowing gradually, so that they overlap with the inevitable wide band, and are smooth and wrinkle-free. The welded edge joint components must be free from pollution sources, moisture, dust, etc. Good reflection in welding, such as immediate cleaning, does not influence the welding quality imperceptibly.
5、 When studying composite geomembrane welding, please ask experienced technicians to weld. There is a hot melt welding machine. It is reported that the thickness of composite geomembrane depends on the welding machine. The temperature and progress must be adjusted accurately, and the thickness of composite geomembrane is not far behind 0.1 mm， If it is too thin, it is easy to break when welded, and the anti-seepage function of the composite geomembrane is reduced due to damage during utilization.
6、Generally, the welding masters assigned by the supply and marketing cooperatives are all specifically involved in welding and have never been inspected by adding materials. Whether buying materials or looking for regular large manufacturers, we will add materials on the spot. First time insurance product quality.
