双向拉伸塑料土工格栅
Biaxial plastic geogrid
产品介绍：以聚合物（聚丙烯或高密度聚乙烯）为主要原料，加入纳米级碳黑，经挤出连续的板材，在板材上有规则的冲孔，然后对网板进行加热、拉伸（单向或先单向后双向）。拉伸过程使原来散孔分布的团状分子链沿拉伸方向重新定向排列，呈直线状态，从而使土工格栅的拉伸强度大大增加，拉伸应变和蠕变应明显降低，提高了材料的力学性能。
Introduction:The polymer (polypropylene or high density polyethylene) as the main raw material, nano-carbonblack, after extruding then become sheet, there are regular holes in the plate, and then heating, stretching (uniaxialor biaxial ) to the web board. So that the original pore will be rearranged along tensile direction to make the pore inline, so increased the tensile strength of geogrid greatly, and the creep strain should be significantly reduced,thereby improving the material mechanical properties.
