Polyethylene polypropylene, polyethylene, polypropylene manufacturers, provided by the double-double woo woo waterproof waterproof. Shouguang City, double-Waterproof Materials Co., Ltd. (www.shuangyufangshui.com) Shandong Weifang quality certified company Commercial Union, with Yu Wang, Chun Hing and other brands, has a good reputation, honesty, service-oriented, "click on the page quotient Union Support "icon, we will be happy to serve you! Polyethylene composite waterproofing membrane should avoid contact with chemicals affect the performance of polyethylene with acids, alkalis, mineral oil, petrolatum, etc., and should avoid contact with high temperature above 80 ℃ in order to avoid permanent deformation membrane. Transport and storage, should be careful not to damage the packaging, placed in ventilated, dry place, storage stack height should not exceed five flat coil volume level. Polyethylene and polypropylene waterproofing membrane laid paste the following provisions shall operate (1). Coil paste determine the direction. When the slope of 3%, the membrane may be parallel or perpendicular to the slope paving. Requirements: upper and lower coil shall mutually perpendicular paving. (2) before basement waterproofing layer construction, should be good nodes, additional layers and pile foundation reinforced parts of the treatment is relatively concentrated, and then upward from the lowest elevation of the construction. (3) polyethylene polypropylene polyethylene polypropylene waterproof membrane before pasting in the web site of the pre-amp laying around 3-12 m polyethylene fiber manufacturers, looking for the positive direction, the intermediate fixed. The coil at one end to a fixed volume polyethylene polypropylene prices, adhesive coating shop, which ends after the paste, and then roll the other end of the pre-amp volume has been glued back to a good position, until the entire continuous paste. (4) Method glue laying: First would have been good preparation with a small plastic container fell on the screed at the pre-sticky glue to continuous evenly, no accumulation is not open at the end, the thickness should be maintained at 1mm, and then shop the web scraper exhaust compaction, discharge excess glue. (5) membrane using the method of paving lap, lap seam roll width: the long side and the short side are 100mm, upper and lower, take junction membrane adjacent two main seams and waterproof layer and the additional layer overlap joints should be staggered 1/3 of the width or more. (6) Coil knot stitch ride full of sticky, compacted after the seam edge at the seams and then brushing a layer of cement paste will be tightly sealed seams, the seams are not allowed open at the end, to fight wrinkles, warping, empty since the phenomenon . (7) vertical longitudinal plane must be pasted pasted composite membrane, from the top down on the positive, bottom-up exhaust compaction requirements while primary and coil coating, roll over sticky.
