Geomembranes are the most widely used products for solid waste containment (such as landfill liners), mining and water containment applications. 
     Resistance to -10 and +97 degrees Resistant to algae growth High strain Resistible to chemical reactions And ... Geomembranes are made from relatively thin continuous polymeric sheets, but they can also be made from the impregnation of geotextiles with asphalt, elastomer or Polymer sprays, or as multilayered bitumen geocomposites. In this discussion, we will focus on continuous polymer sheet geomembranes since they are, by far, the most common. The manufacturing of geomembranes begins with the production of the raw materials, which include the polymer resin itself: various additives such as antioxidants, plasticizers, fillers, carbon black, and lubricants (as a processing aid). These raw materials (i.e., the 'formulation') are then processed into geomembrane sheets of various widths and thickens by one of three ways; extrusion, calendering, and spread coating.

HDPE Geomembrane Application: 

Geomembrane is widely used in environmental protection/sanitation (such as domestic waste landfills, sewage treatment, toxic and hazardous materials disposal sites, dangerous goods warehouses, industrial waste, construction and blasting waste, etc.) and water conservancy (such as rivers, lakes, reservoirs, dams, etc.) Anti-seepage, plugging, reinforcement, seepage prevention of water canals, vertical core walls, slope protection, etc.), municipal engineering (underground engineering of subways, buildings and roof reservoirs, anti-seepage of roof gardens, lining of sewage pipes, etc.) ), gardens (artificial lakes, ponds, golf course pond bottom lining, slope protection, etc.), petrochemicals (chemical plants, refineries, gas stations, anti-seepage of oil storage tanks, chemical reaction tanks, lining of sedimentation tanks, secondary Lining, etc.), mining (washing tanks, heap leaching tanks, ash dumps, dissolution tanks, sedimentation tanks, storage yards, tailings ponds, etc.), agriculture (reservoirs, drinking water tanks, storage ponds) , Irrigation system seepage prevention), aquaculture (fish ponds, shrimp pond lining, sea cucumber ring slope protection, etc.), salt industry (salt field crystallization pond, brine pond thatch cover, salt film, salt pond plastic thatch film) and many other fields In the seepage control project.

Packaging & Shipping

Our efforts to ensure the safety of long-distance transportation:
 

In order to ensure the safety of long-distance transportation, G-MAX designed different product packaging protection measures for sea transportation and air transport to ensure the safety of products in the course of transportation. At the same time, we work with FedEx, EMS, UPS,TNT,DHL and other global logistics companies to ensure that the delivery time requirements are relatively tight customers, in a relatively short period of time to receive the required products.
