Pre-laying ceremony for waterproofing polymer adhesive film "a" product overview and product images Overview 1 Product Overview pre-shop type polymer adhesive film waterproofing membrane quality HDPE polyethylene geomembrane virgin polyethylene resin , the main component of high-density polyethylene, carbon black, anti-aging agent, an antioxidant, an ultraviolet absorber, stabilizer material web coextrusion technology products. 2, product images Overview Second, product characteristics 1, chemical stability, having good chemical stability, high temperature, bitumen, oil and tar, acid, alkali, salt and other chemical corrosion. 2, anti-aging properties, good anti-aging, anti-UV, anti-catabolic properties, provide a good security environment impervious material. 3, high mechanical strength, excellent mechanical strength has, expansion or contraction of the tensile properties and deformation capacity makes it an ideal base surface, can effectively overcome the uneven settlement of the base surface. 4, the construction speed, the use of hot-melt welding, weld strength, construction convenient, fast. 5, environmental non-toxic, high-quality original plastic and carbon black reinforcement, no preservatives, dense material flow principle, does not produce any harmful substances, it is the best choice, environmental protection, agriculture, drinking water. Third, product specifications width: 3000,4000,3000,4000,7000,8000,9000 mm; thickness: 0.5,0.75,0.5,0.75,1.50,2.00,2.50,3.00 mm (smooth geomembrane); 1.00,1.25, 1.50,1.00,1.25,3.00 mm (Matte geomembrane). Fourth, self-adhesive polymer film (pre-coated) waterproof membrane construction process 1, prior to construction, materials should be stored properly, it should be marked with its mounted position in the whole program. 2, polymer adhesive film (pre-coated) waterproofing membrane should be able to complete more than one working day. 3, prior to construction, should check their film in the protective layer, per square meter of flatness error does not exceed 2 mm. 4, laying should start once in place, should not be dragged before the start. 5, pre-shop type waterproofing size should change the amount of stretch material thermal expansion and contraction caused by spare. 6, when the laying of the installation, try to avoid cross welds, T-joints in general use. 7, after the completion of HDPE film to expand, it is timely welding, heat staking lap width of 100 ± 20 mm, extrusion welding lap width 75 ± 20 mm. V. Notes 1, the pre-shop type polymer adhesive film for waterproofing cold-construction, like Mars, such as welded steel produced, weld the membrane surface need to set up interim measures of protection. 2, after the completion of the laying sheet, pay attention to the follow-up of protection to this principle reinforced Longzhe light up and drag on is not waterproof layer to prevent damage to waterproof layer. After torn insulation film, to avoid the adhesive surface is contaminated and spread a layer of cement powder do isolation. 3. Packaging: bags. (1) Storage: Store in a dry, cool, clean warehouse, and near heat sources. Since the date of production storage period not exceeding two years. (2), Transportation: transport process should avoid the sun, pollution, stress, strong shocks and scratches, and so on, to keep the packaging intact. Six, engineering vision
