垃圾填埋场用高密度聚乙烯土工膜（普通糙面膜）
High density polyethylene geomembrane used in landfill(normal textured geomembrane)
产品介绍:：高密度（HDPE）聚乙烯普通糙面土工膜是由特殊配方的原生树脂，经一定工艺手段生产的单面或双面
具有均匀毛糙外观的高密度聚乙烯（HDPE）土工膜。
Introduction: high density polyethylene(HDPE) textured geomembrane ,made of virgin resin by special
production ,has even and smooth surface on both sides.It is especially designed for flexible geomembrane.
产品规格：厚度1.0～3.0㎜，幅宽4～9m，长度根据工程设计和客户要求。
Specification:thickness ranges from 1.0mm to 3.0mm,width from 4m to 9m.The roll length can be made according
to design or customer request.
产品特点：具有优异的防渗防污性能，机械性能优异，尺寸稳定性、化学稳定性和耐热老化性能良好，同时具有优
异的抗紫外线辐射性能。摩擦系数大，还具有防滑作用，非常适合于垃圾填埋场的四周边坡铺设，便于土工织物的二
次铺设，同时可以增强膜的抗承载变形力。一般应用在边坡膜体表面需要覆土，要求有较大摩擦系数的项目中。
Property: :HDPE normal textured geomembrane has excellent chemical and mechanical property,anti-crack
property,dimensional stablility and anti-aging property,furthermore it can be exposed for anti-UV property.
