Geomembrane

The HDPE smooth (rough) geomembrane is manufactured with high-quality high-density polyethylene resin and imported from Germany with flat extrusion equipment and four layer co extrusion blown film equipment. Complete specifications; Smooth (rough) geomembrane thickness: 0.25-3.0mm, with a maximum width of up to 8m.

*Environmental protection projects such as garbage disposal sites, sewage treatment plants, petrochemicals, metallurgy, etc;

*Water conservancy projects such as reservoirs, embankments, rivers, lakes, etc;

*Subway, tunnel, underground warehouse, etc;

*Artificial lakes, scenic spots, and other landscaping projects;

*Construction market and other waterproofing projects;

1.With a bult-in protector,the motor turns off automatically when overheated or when the three-phase mains loses phase, so as to protect the motor from burning out;

2.The gear is made of chromium-manganese-titaium alloy sleel,with carbonitriding on the surface,which can prolong life span greatly;

3.To ensure endurable use in the sea water or highly erosive industrial waste,engineering plastic impaller and stainless steel impeller are deyeloped according to the requirements of varied usage environments and specific demands of users,eliminating the need of frequent change of impellers or painting.
