1. Introduction to HDPE geomembrane:
1. As a new type of material, HDPE geomembrane has excellent anti-seepage and anti-corrosion properties, good chemical stability, and can be processed according to actual engineering needs. It has been widely used in embankments, dams, and water conservancy projects. Anti-seepage of reservoir.
2. It is also used as anti-seepage, anti-corrosion, leak-proof and moisture-proof materials in channels, reservoirs, sewage pools, swimming pools, house construction, underground buildings, garbage dumps, environmental engineering, etc.
2. HDPE geomembrane production process:
Raw material preparation--production line preparation--extrusion preparation--automatic feeding--heating extrusion--blowing--circulation cooling--product molding--traction--winding--inspection--packaging and storage.
3. Classification of new material geomembranes:
1. According to the different 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) membrane), polyvinyl chloride geomembrane (PVC geomembrane) and ethylene-ethylene copolymer geomembrane (EVA geomembrane), etc.
2. Depending on the quality of raw materials:
It can be mainly divided into national standard type one geomembrane (GB/T17643-2011 GH-I type), national standard type two geomembrane (GB/T17643-2011 GH-II type environmental protection type), and urban construction standard geomembrane (CJ/T234-2006 )wait. Special geomembranes for anti-seepage in landfills are mainly urban construction geomembranes.
3. Depending on the appearance of the product:
It can be mainly divided into smooth geomembrane, single rough geomembrane, double rough geomembrane and pillar geomembrane. The special geomembranes for landfill slope anti-seepage are mainly single-rough surface geomembranes and double-rough surface geomembranes, while the special anti-seepage geomembranes for the bottom of landfill sites are mainly smooth surface geomembranes.
4. According to different product specifications and thickness:
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, etc.
