Geotextile Edison filament geotextile, also known as geotextile, it is following the steel, cement fourth largest building materials. Our production since the 1980s and the development and application of geotextiles, the current production capacity has reached 200 million square meters, The main varieties are: woven geotextile, fine for geotextiles, non-woven staple acupuncture geotextile, spunbonding geotextile, geomembrane and other complex so some manufacturers also developed a jute geotextile, reinforced non-woven geotextile. acupuncture combination of non-woven geotextile composite geotextile patch rubber waterproof plate and other new products. Some have applied for national patents, of which the non-woven geotextile about 70% of these goods in road, rail, water, sea wall The application test results show that the application of geotextiles can accelerate construction progress, improve project quality, save raw materials and the cost of overseas since the 1970s and is widely used geotextile, and rapid development, in 1985 the world's total production of 400 million geotextile square m filament geotextile, to 1990 has reached 10 million square meters, the annual growth rate of around 20%. With the wide application of geotextiles, geotextile functional requirements of a higher filament geotextile manufacturers, the the world has successively developed many new varieties of high strength fibers such as polypropylene discrete - soil mixing products, non-woven geotextile - Trellis composite products, non-woven geotextile - other building complex products to meet the construction requirements level discussions on the permeability of geotextile filament in the use of our products, but we must first learn to understand the product, only we truly know the will of the display to maximize their value. Seminar thesis show: polyvinyl chloride filament geotextile certain other conditions, the greater the degree of surface density, the greater its level of permeability coefficient; increasing level of permeability coefficient decreases gradually with the law to pressure; constant with pressure increasing its level of penetration coefficient of variation of the amplitude gradually decreases; thinks fit using two plate of polyvinyl chloride filament geotextile easiest surface penetration experienced purposes mimic find fractal analysis of theoretical plates than mimic type Resistance is more feasible type of theoretical plates; the use of fractal analysis of theoretical plates mimic the type of polyvinyl chloride standard filament geotextile permeability coefficient larger than the experimental values ??widespread. Based subject Darcy (Darcy) Theorem practical filament geotextile fabric bonding seminar ponder ancient clues vertical permeability, unless deemed appropriate plate type using resistance theory and fractal analysis of theoretical plates type establish a filament geotextiles Experienced plate penetration level, then, the experimental values ??and the plate mimic a standard filament geotextile permeability coefficient to fit, are provided to check looks for the built-plate for filament geotextile easiest surface penetration Experienced mimic the works of the merits and fitting results. Practical filament geotextile, geotextile filament Xinxiang, Edison Group Edison new material provided by the Corporation. Edison New Materials Co., Ltd. (www.fangshenmo.com) strong, credible, in Dezhou site construction materials industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Edison new materials into the brilliant and you work for a better future!
