136 * 6868 * 8676 drainage board products from the raw materials used are classified, there are mainly two: Polypropylene drainage board. Polypropylene the drainage board olefin material a thermoplastic, high strength, deformation elongation properties, good processing performance materials, but the tear strength of the polypropylene sheet is lower, and is easily formed into a special shape, it is possible to fill plus a The amount of mixing materials and improve the hardness of the material. Many of the world's polypropylene production drainage board, whichever is easy to process molding characteristics. High-density polyethylene (HDPE) drainage board. A high density polyethylene (HDPE) is an olefin-based material, its molecular structure the nonpolar (charge), a thermoplastic, high hardness, high strength, good elongation deformation, high tear strength, and can only be mixed with the feed is less than 2.0% admixture, it is pure polyolefin material, its biggest feature is resistance to environmental corrosion, general acid, alkali, salt formation of HDPE corrosion damage, so the the worldwide municipal waste words too landfill HDPE film for anti-seepage system. HDPE industrial processing performance, particularly in the plastic processing more difficult, so the use of the of HDPE production drainage board production process more complicated, many companies prefer to use polypropylene production reasons drainage board. In summary, the continuous sheet bump pressure drainage board filamentous composite drainage board; planted roof, underground garage roof, transportation platform works far better than in the draining football field athletic field, filamentous stack joint drainage board more quickly than the continuous sheet the bump-pressure drainage board drainage effect. From durable, weather resistance, resistance to environmental corrosion resistance, overburden pressure, high-density polyethylene (HDPE) drainage board is superior to polypropylene drainage board, which is the material aspects of the reasons for the decision. Sales Hotline 136 * 6868 * 8676 drainage board thickness is determined by the space maximum drainage capacity of the drainage board, but the northern region is a serious lack of rain in the region, the Beijing area statistics for many years maximum 24-hour rainfall of only 113mm, one hour maximum rainfall 33 mm. To 300mm thick planting soil, and the soil is saturated (In the original soil humidity is 50%) can absorb rainwater 65mm, the rainfall penetration to the the drainage board requires hysteresis 3 hours, the water resistance of soil, water penetrated into the drainage board slow, the intensity of the permeated water is less than 20 mm / hour. Too much emphasis on the drainage capacity (displacement) is often misleading consumers because the drainage board the thicker the higher the price. Of course, a large displacement of the drainage board will not impair the function and roof. In the south of the Yangtze River in China, planting soil thickness more than 250mm, 8mm thick drainage board fully meet the requirements. All parts of the country, planting soil thickness greater than 500mm, 8mm thick drainage board fully meet the ecological requirements. Southern rainy regions, such as Guangdong, Guangxi, Taiwan and other sub-tropical climate, when the planting soil is less than 200mm thick, the need to enhance the drainage function, while still using 8mm thick drainage board, it will not cause the plants to waterlogging. Engineering Drainage Board, in principle, need to go through the professional design, in order to maximize the use of the drainage board potential. 136 * 6868 * 8676 Main drainage board, drainage board storage, geotextile, geomembrane, grass grid, composite drainage board, composite geomembrane. Engineering building materials research, development, production and construction in one integrated enterprise. The company produces engineered geotextile material: drainage board, geotextile (non-woven), build drainage board, geomembrane, grass grid, geomembrane, composite drainage board, drainage waterproof material. Companies from Italy, Austria and other countries to introduce a full set of the world's advanced level of the drainage board production line, geotextile composite geomembrane production line, annual production capacity of 6,000 tons, complete specifications arbitrary choice, product technical indicators have exceeded the national standard. Professional production of various airport projects, highway, tunnel engineering, municipal engineering, the basement moisture seepage drainage board and landscape garden materials build drainage board, grass grid. Our products are mainly used in water conservancy construction, highway, airport engineering, highway, tunnel engineering, municipal engineering, basement moisture impermeable drainage board, and landscaping build drainage board, grass grid, environmental protection and other infrastructure areas, has been widely used large reservoirs, highways, tunnels, railways, golf courses, landfills and many other national key projects, engineering experts praise. The company has always been customer satisfaction as the highest goal, for the purpose of operating in good faith, willing customers at home and abroad to work together to create a better tomorrow!
