1、 Introduction to HDPE Geomembrane:
1. HDPE geomembrane, as a new type of material, has excellent anti-seepage, anti-corrosion performance, good chemical stability, and can be processed according to actual engineering needs. It has been widely used for anti-seepage of embankments, dams, and reservoirs in hydraulic engineering.
2. At the same time, it is also used as anti-seepage, anti-corrosion, leak proof, and moisture-proof materials in channels, reservoirs, sewage pools, swimming pools, building construction, underground buildings, garbage disposal sites, environmental engineering, and other aspects.
2、 HDPE geomembrane production process flow:
Raw material preparation - production line preparation - extrusion preparation - automatic feeding - heating extrusion - blowing - circulating cooling - product forming - traction - winding - inspection - packaging and warehousing.
3、 New Material Geomembrane Classification:
1. According to the different materials of the raw materials:
It can be mainly divided into high-density polyethylene geomembrane (HDPE geomembrane), medium density polyethylene geomembrane (MDPE geomembrane), low-density polyethylene geomembrane (LDPE geomembrane), linear low-density polyethylene geomembrane (LLDPE geomembrane), polyvinyl chloride geomembrane (PVC geomembrane), and ethylene ethylene copolymer geomembrane (EVA geomembrane).
2. Depending on the quality of the raw materials:
It can mainly be divided into National Standard Type I Geomembrane (GB/T17643-2011 GH-I type), National Standard Type II Geomembrane (GB/T17643-2011 GH-II environmentally friendly type), Urban Construction Standard Geomembrane (CJ/T234-2006), etc. The anti-seepage special geotextile for landfill sites is mainly composed of urban construction geotextile.
3. According to the different appearance of the product:
It can be mainly divided into smooth surface geotextile, single rough surface geotextile, double rough surface geotextile, and column point geotextile. The special geotextile membrane for seepage prevention of landfill slopes is mainly composed of single rough surface geotextile membrane and double rough surface geotextile membrane, while the special geotextile membrane for seepage prevention of landfill bottom is mainly composed of smooth surface geotextile membrane.
4. Depending on the thickness of the product specifications:
From 0.2mm to 2.0mm, it can be mainly divided into 0.2mm geomembrane, 0.5mm geomembrane, 0.75mm geomembrane, 1.0mm geomembrane, 1.5mm geomembrane, and 2.0mm geomembrane.
