在选择土工膜过程中我们应该跟关注哪些方面 What aspects should we pay attention to when selecting geomembranes

一、什么是土工膜

1、 What is Geomembrane

土工膜是由一种高分子聚乙烯化学材料加工而成，比重小，延展性强，且具有耐低温高温、抗冻性好的特点。土工膜普遍应用于人工湖、蓄水池、垃圾填埋场、储油罐防渗、堆灰场、建筑物地下工程、沉淀池的内衬等社会生活的各个方面。

Geomembrane is processed from a polymer polyethylene chemical material, with a small specific gravity, strong ductility, and good resistance to low temperature, high temperature, and freezing. Geomembranes are widely used in various aspects of social life, such as artificial lakes, reservoirs, landfills, oil storage tank anti-seepage, ash storage yards, underground engineering of buildings, and the lining of sedimentation tanks.

二、防水土工膜什么特性

2、 What are the characteristics of waterproof geotextile film

防水土工膜不但节约成本，而且更有利于防渗处理，对于要求防渗性能高的工程，选择优质的厚一点的或者复合土工膜，甚至防水毯，这样防渗性能更好，使用寿命更长。

Waterproof geomembranes not only save costs, but also are more conducive to anti-seepage treatment. For projects that require high anti-seepage performance, choose high-quality thick or composite geomembranes, or even waterproof blankets, which have better anti-seepage performance and longer service life.

三、各种类型土工膜应用哪些方面

3、 What are the applications of various types of geomembranes

1）HDPE土工膜主要应用于垃圾填埋场、污水处理厂、电厂调节池、工业、医院固体废弃物等。

1) HDPE geomembrane is mainly used in landfill sites, sewage treatment plants, power plant regulating ponds, industrial and hospital solid waste, etc.

2）高密度聚乙烯膜用于化工厂、炼油厂、储油罐防渗、化学反应池、沉淀池的内衬等。

2) High density polyethylene film is used for the lining of chemical plants, refineries, oil storage tanks, chemical reaction tanks, sedimentation tanks, etc.

3）LDPE防渗膜适用农业：水库、饮用水池、蓄水塘的防渗。

3) LDPE anti-seepage film is suitable for agriculture: anti-seepage of reservoirs, drinking water pools, and storage ponds.

四、我们实际的选购土工膜时候

4、 When we actually purchase geomembrane

首先考虑工程实际需求，另外，根据实际应用的土工膜种类，对比土工膜价格，不是价格越低就选购，一定看好土工膜的品质，为了工程的防渗更好更持久，选择优质靠谱的土工膜厂家。

Firstly, consider the actual needs of the project. In addition, based on the types of geomembranes used in practice, compare the prices of geomembranes. It is not advisable to purchase geomembranes at lower prices. We must be optimistic about the quality of geomembranes. In order to ensure better and more sustainable seepage prevention in the project, we should choose high-quality and reliable geomembrane manufacturers.
