hdpe geomembrane liner Manufacturers

Waterproof geotextile is actually a composite geomembrane, but two names for a product. Waterproof geotextiles are divided into one fabric and one membrane, two fabrics and one membrane, and multiple fabrics and multiple membranes.

Composite geomembrane is a composite impermeable material, woven or non-woven fabric is used as reinforcement material, and polyethylene is used as impermeable material. Most of the materials are one cloth and one film, and two cloth and one film. Laying impermeable membrane procedure: When laying the impermeable membrane, please make sure that there is no gap in the corner. If there are gaps, they should be filled in time during construction, and the laying order should be determined according to the specific conditions of the moisture content of the laying site. If there are pores, the air should be vented at the air bubble, and the anti-permeable membrane at the vent should be cleaned for subsidies.

High strength, good self-tightness, high elongation, aging resistance, non-toxicity, no pollution to the environment, etc.,

Film welding method 1. The welding temperature, speed and pressure are determined after experiments and inspections. 2. The welding should be stopped when the ambient temperature is too high or too low. 3. The welding rod is the same as the membrane material. 4. Every piece of oilfield impermeable membrane is welded on the day of laying. 5. The edge of the upper impermeable membrane at the weld should be polished to an inclination angle of 45° to improve the welding quality of the weld.

Most nonwoven polypropylene bags are also made of 5-type recyclable plastic.

The same geomembrane product can be used in different places, and different geomembrane products must be used in the same place.
