Green Sanjiang plastic drainage board applied Master roof, drainage board bump down to use, find the slope layer as a vent layer using plastic drainage board green rivers, including the use of the wall: as interior drainage layer, reducing the Basement osmotic water pressure. Green rivers drain construction technology and Notes 1. drain construction base surface must be firm, smooth, we can not have a crisp before starting cleaned sand, tilt and tip convex, potholes and other phenomena construction. 2. Drain in a flat base surface covered, build drainage board bump laying down, engaging with each other, then laid non-woven polyester, can overlap; single laying drainage board bump up. Engaging lap or welding build drainage board prices, overlying flat screen support, then laid non-woven polyester, can overlap. 3. In order to prevent damage to the vehicle to build drainage systems, backfill backfill needs from the periphery inward, process as follows:. ① water on board, and then backfill ② after the completion of the first non-woven laying backfill backfill thickness is disposable. more than 400mm thick, compacted backfill before they can walk in the vehicle ③. manual configuration required backfill planting soil, no natural backfill compaction. We all know that plastic drainage board core board using polypropylene and polyethylene blend, so all the advantages of plastic drainage board has two materials, then what are polypropylene and polyethylene it? Polypropylene is a fusion of a hot melt type resin drainage board price made with propylene, and it is a non-toxic, odorless, tasteless milky highly crystalline polymer, the quality is very light. It is one of the lightest of all plastic varieties, is the application of plastic drainage board this feature, so the plastic drain well reduce the load forces of the building. Polypropylene has a lot of advantages, such as good bending resistance of polypropylene, commonly known as the pleated plastic. Secondly, there is a strong polypropylene thermal conductivity, without being subject to external conditions, 150 degrees Celsius and not returning deformation. Its chemical properties are stable plastic drainage board prices, not easy to be corroded. Anti-voltage aging. Of course, he also has a lot of shortcomings, such as poor cold products, low temperature impact strength. Products subject to the action of light, heat and oxygen in use and aging. Coloring is not good. Flammable. Good toughness, high static, dyeing, printing and poor adhesion. So plastic drainage board production is the use of a combination of polypropylene and polyethylene made of polyethylene it is easy to make up for some of the lack of a polypropylene material. Polyethylene is a Champions League hot-melt type resin formed by polymerization of ethylene, which is odorless Shandong drainage board price, non-toxic, feel like wax, has excellent low temperature properties, good chemical stability, resistance to most acid-base erosion . Room temperature, not soluble in common solvents, water absorption, excellent electrical insulation properties. Polyethylene wide range of applications, in addition to blend with polypropylene plastic drainage board, but also often been widely used in manufacturing films, hollow articles, fibers and sundries and so on. To compensate for the lack by polyethylene polypropylene, so plastic drainage board has most of the advantages of polypropylene and polyethylene, plastic drainage board application so the popularity is great. In addition to plastic drainage board core board is made of polypropylene and polyethylene blend outside, there is a layer of plastic drainage plate membrane, the membrane is pierced with a hot filament nonwoven fabric made of a resistance to flooding, seepage performance is extremely good.
