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 should focus on to draw attention to the polyethylene sheet plywood, we recommend welding polyethylene sheet polyethylene sheet, using double seam automatic welding and manual crawling plastic hot air gun for manual welding, welding polyethylene sheet because it can be formed tight waterproof layer. High density polyethylene sheet is environmentally friendly materials, heating to the melting point, can be recycled. Notice of plastic materials can be divided into two large categories: "thermoplastic plastic" (Thermoplastic) and "thermosetting plastic" (Thermosetting) polyethylene sheet, "thermosetting plastic" is heated to a certain temperature into cured state, even though we continue heating also can not change its state, high molecular weight polyethylene sheet, are environmentally friendly products in question are "thermosetting plastic" products (such as tires), not "thermoplastic plastic" products (such as plastic pallets NOTE: pallets in Hong Kong and Macao are called as "splints"), so not all "plastic" neither environmentally friendly. High molecular weight polyethylene sheet, polyethylene sheet, Yu-plastic quality provided by the Dezhou Yu-Plastic Products Co., Dezhou Yu-Plastic Products Co., Ltd. (www.dezhouyuang.com) (www.dezhouyuang.com) strong, credible, in Dezhou engineering plastics industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Yu-plastic products into the brilliant and you work for a better future!
