Polyethylene sheet is well applied to green building construction waterproofing layer application, we in this project by applying polyethylene sheet a good solution because the plant roots have a strong vigor, waterproof layer can easily be pierced issues. Polyethylene sheet in the project construction process generally: the grass-roots acceptance, empty shops polyethylene drainage board, drainage board connections, and other important aspects of inspection and acceptance. Which draw attention to focus on that, we recommend welding of polyethylene sheet, double seam automatic welding and manual crawling plastic hot air welding torch for manual welding, welding polyethylene sheet because it can form tight waterproof layer. UHMWPE sheet has high strength and impact resistance of the polymer polyethylene sheet, ultra high molecular weight polyethylene sheet quality smooth surface, low coefficient of friction polyethylene sheet purposes, and excellent abrasion resistance polyethylene sheet, for cushioning material, such as a bed of cushioning buffer panel has a great advantage. Another can effectively ensure polyethylene sheet contact surface and the surface of the conveyor belt, even by force, to effectively prevent fracture due to the roller, belt longitudinal tear caused by falling, while significantly reducing the belt to be sharp or sharp materials After penetrating the probability of longitudinal tear. High density polyethylene sheet _ Yu-plastic products (certified) _ polyethylene sheet provided by the Dezhou Yu-Plastic Products Co., Dezhou Yu-Plastic Products Co., Ltd.
