糙面土工膜知识与应用 Knowledge and Application of Rough Geomembrane

糙面土工膜：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，经特殊压延工艺生产的单面或双面具有糙面外观的高密度聚乙烯（HDPE）土工膜。摩擦系数较。

Rough geomembrane: High density polyethylene (HDPE) ordinary rough geomembrane is a high-density polyethylene (HDPE) geomembrane with a rough appearance produced by a special formula of native resin and special rolling process on one or both sides. The friction coefficient is relatively high.

产品规格：厚度1.0～3.0㎜，幅宽4～9m，长度根据工程设计或客户要求。

Product specifications: thickness 1.0-3.0 mm, width 4-9m, length according to engineering design or customer requirements.

产品特点：糙面土工膜除具有的化学稳定性、力学性能、耐环境应力开裂性能、尺寸稳定性和耐热老化性能、抗紫外线辐射性能外，还具有摩擦系数大，防滑作用好的特点，非常适合于垃圾填埋场的四周边坡铺设或陡坡和垂直防渗，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，要求有较大摩擦系数的项目中。我公司生产的该产品性能指标普通糙面土工膜两倍，提高工程稳定性。

Product features: In addition to its chemical stability, mechanical properties, environmental stress cracking resistance, dimensional stability, heat aging resistance, and UV radiation resistance, rough geomembrane also has the characteristics of high friction coefficient and good anti slip effect. It is very suitable for laying around slopes or steep slopes and vertical anti-seepage in landfill sites, facilitating the secondary laying of geotextiles, and enhancing the membrane's load-bearing and deformation resistance. It is generally used on the surface of slope membranes and requires projects with a large friction coefficient. The performance index of this product produced by our company is twice that of ordinary rough geomembrane, improving engineering stability.
