EVA geomembrane-EVA土工膜

性能特点：

Performance characteristics:

1、防渗系数高—防渗膜具有普通防水材料无法比拟的防渗效果，HDPE防渗膜具有高强抗拉伸机械性，它良的弹性和变形能力使其非常适用于膨胀或收缩基面，可有效克服基面的不均匀沉降,水蒸汽渗透系数K<=1.0*10-13gcm/ccm2spa；

1. High anti-seepage coefficient - The anti-seepage film has an unparalleled anti-seepage effect compared to ordinary waterproof materials, while HDPE anti-seepage film has high-strength tensile mechanical properties. Its good elasticity and deformation ability make it very suitable for expansion or contraction of the base surface, effectively overcoming uneven settlement of the base surface. The water vapor permeability coefficient K<=1.0 * 10-13gcm/ccm2spa;

2、耐老化性能—防渗膜具有秀的抗老化、抗紫外线、抗分解能力，可裸露使用，材料使用寿命达50-70年，为环境防渗提供很好的材料；

2. Anti aging performance - the anti-seepage membrane has excellent anti-aging, anti ultraviolet and anti decomposition capabilities, which can be used naked. The service life of the material can reach 50-70 years, providing good materials for environmental anti-seepage;

3、高机械强度—防渗膜具有良好机械强度，断裂拉伸强度28MPa，断裂延伸率700%；

3. High mechanical strength - The anti-seepage film has good mechanical strength, with a tensile strength of 28MPa at break and an elongation at break of 700%;

4、抗植物根系—HDPE防渗膜具有异抗穿刺能力，可以抵抗大部分植物根系；

4. Anti plant root system - HDPE anti-seepage film has the ability to resist puncture and can resist most plant roots;

5、化学稳定性—防渗膜具有异的化学稳定性，被广泛用于污水处理，化学反应池，垃圾填埋场。耐高低温，耐沥青,油焦油，耐酸、碱、盐等80多种强酸强碱化学介质腐蚀；

5. Chemical Stability - Anti seepage membranes have different chemical stability and are widely used in sewage treatment, chemical reaction tanks, and landfill sites. Resistant to high and low temperatures, asphalt, oil tar, acid, alkali, salt, and more than 80 strong acid and alkali chemical media corrosion;

6、施工速度快—防渗膜有很高的灵活性，有多种规格多种铺设形式满足不同工程防渗要求，采用热熔焊接，焊缝强度高，施工方便、快速健康；

6. Fast construction speed - The anti-seepage membrane has high flexibility, with various specifications and laying forms to meet different anti-seepage requirements of engineering. It adopts hot melt welding, with high weld strength, convenient, fast, and healthy construction;

7、成本低效益高—HDPE防渗膜采用新型技术提高了防渗效果，但生产工艺加科学、速捷、所以产品成本反而低于传统防水材料，经实际测算采用HDPE防渗膜的一般工程要节约成本50%左右；

7. Low cost and high efficiency - HDPE anti-seepage film adopts new technology to improve its anti-seepage effect, but the production process is scientific and fast, so the product cost is actually lower than traditional waterproof materials. According to actual calculations, using HDPE anti-seepage film in general engineering can save about 50% of the cost;

8、性—防渗膜采用的材料均为材料，防渗原理是普通物理变化，不产生任何有害物质，是、养殖、饮用水池的选择。

8. Properties - The materials used for the anti-seepage membrane are all materials, and the anti-seepage principle is ordinary physical changes that do not produce any harmful substances. It is the choice for aquaculture and drinking water tanks.
