Description :

　　Dezhou Zhengyu Geotechnical Materials Co., Ltd. manufactures and sells woven geotextiles (also known as horticultural ground fabrics, grass proof fabrics), composite films, waterproof blankets, carpets, waterproof boards, woven fabrics, woven bags, ecological bags, geogrids, geogrids, geogrids, waterstops, waterstops, HDPE pipes, HDPE film materials, blind ditches, waterproof and drainage combinations, expansion joints, and drainage board products, and operates import and export business. The woven geotextile produced by the company, also known as grass proof cloth, is divided into 90 grams of grass proof cloth (horticultural ground cloth), Ningxia double rough surface HDPE anti-seepage film black film biogas digester, and 2.0 single rough surface HDPE film 100 grams of horticultural ground cloth (grass proof cloth), which are exported to domestic and foreign markets and widely used in agricultural planting and green agriculture promotion. Inner Mongolia's smooth HDPE anti-seepage film agricultural irrigation water tank produces 26 million square meters of woven geotextile (anti grass cloth) annually with 1.5 pairs of rough HDPE film. The production equipment is relatively advanced, including 6 sets of 4-meter wide horticultural geotextile (anti grass cloth) production equipment (circular weaving machine), 1 set of 6.2-meter wide geotextile production equipment (circular weaving machine), 5 sets of 6-meter wide anti grass cloth (circular weaving machine) equipment, 3 sets of 4-meter wide flat weaving machine equipment, 1 set of 8-meter wide horticultural geotextile equipment (circular weaving machine), Ningxia's double rough HDPE anti-seepage film black film biogas digester, and 2.0 single rough HDPE film. This 8-meter wide production equipment is currently the largest wide woven geotextile (anti grass cloth) production equipment in China. The sentence is:. Ningxia Double Rough Surface HDPE Anti Seepage Membrane Black Film Biogas Tank, 2.0 Single Rough Surface HDPE Membrane Company is a large manufacturer of woven geotextile (grass proof fabric) in China.

　　Quality Inspection Method for HDPE Geomembrane Hot Melt Double Track Welding

　　There are two types of welding quality testing for HDPE geomembranes: non-destructive testing (leak testing) and destructive testing. The double weld formed by hot melt welding is inspected using the inflation method, while the single weld formed by extrusion welding is inspected using the electric discharge method.

　　1. Inflatable method testing

　　Seal both ends of the HDPE geomembrane weld cavity that needs to be tested. After connecting the testing equipment, insert the measuring needle into one end of the cavity. Start the air pump, input high-pressure gas to reach 0.15~0.2MPa, and stop pressurization. Within 1-5 minutes, there was no significant decrease in pressure. When the other end was opened, the gas in the cavity disappeared. The Ningxia double rough surface HDPE anti-seepage film black film biogas digester and the 2.0 single rough surface HDPE film indicated that the entire weld seam passed the inspection. If the pressure gauge drops significantly within 1-5 minutes, it indicates that this weld seam needs to be repaired or reworked.

　　2. Spark detection method

　　By utilizing the characteristics of HDPE geomembrane as an electrical insulator, bright electrical sparks are generated when the instrument scans a part with holes or holes connected to the ground.

　　Testing procedure: embed fine copper wire before extrusion welding construction. During the inspection, the power supply was connected to the Xinjiang PE film industrial landfill. The 1.5 double rough surface HDPE film was detected with a detector at a height of about 30mm from the weld seam. If no sparks appear, the weld seam is firm. If sparks appear, it indicates that there is detachment, virtual welding, etc. in this area, which needs to be repaired and retested.

　　3. Destructive testing

　　Whether it is HDPE geomembrane double track hot melt welding double weld or extrusion welding single weld, the strength inspection of the weld, including shear strength and peel strength, must be carried out. The strength inspection is conducted at a frequency of testing every 1000 meters of weld seams (with at least five samples per group), designated by the owner or supervisor or randomly sampled for testing. Generally, it is selected to be conducted at locations where overheating, contamination, weld deviation, or insufficient welding are suspected.
