Geomembrane is reinforced modified polyethylene or PVC, calender film forming and polyester geotextile heat is made with a tensile strength, bursting resistance, high tear strength, elongation properties, deformation modulus , anti-aging, anti-seepage performance, use a long period and so on. Geomembrane Due to these characteristics, in Canal Seepage promote the adoption process, and achieved good economic and social benefits. Geomembrane construction defect repair 1. geomembrane construction welding test cut sample parts, material damage and defects discovered after the welding shop, welding defects and defective parts found during inspection, etc., should be repaired ??? 2. Construction of geomembrane repair procedure is: always find the defective portion of the white pen with a special label, and add number recorded in the diary, so as not to miss when repair; mend numbered rule B1, B2, B3 ...... consecutive order; repair programs should be recognized through captain; after the repair should be sampled (10% to 20%) do leak test (vacuum method or spark method). 3. geomembrane Buxiu methods: a spot welding: for less than 5 mm holes and partial weld repair on material improvement, by extrusion welding machine spot welding. . b stamped: tight enough to inadequate thickness or extrusion welding, welding layer of an extrusion welding machine. c patch: For large holes, punctured at the severe damage at the membrane surface, the sampling point, cross stitch and defect site at the intersection of a variety of other factors, it can be stamped with a way to fix the patch. Patch size: Cross joints of 300 × 300 mm square chamfered, or D = 300 mm. In other cases, high-quality anti-Sai geomembrane, generally not less than 200 mm side length, patch the defect is not less than 80 mm margins. 4. geomembrane patch test at: Operation repair tasks can only be carried out under the guidance of senior workers; after the repair of the finished product sampling to make leak test. Geomembrane company professional construction team, another company specializing in the production: filament geotextile, GCL, eva waterproof board. Matte geomembrane performance is very good, well-known anti-Sai geomembrane, geomembrane matte colors are white and black, width: 1-6 meters. Thickness: 0.30-2.00 mm. Manufacturing process is divided into: blown film, cast film. Why matte geomembrane has good heat and cold? The use of ambient temperature is high 110 ℃, low temperature -70 ℃, has good chemical stability, anti-Sai geomembrane characteristics, acid, anti-Sai Nanjing geomembrane, alkali, corrosion of oil is a good anti-corrosion materials ??? Matte geomembrane with high tensile strength, it has a high tensile strength to meet the high standards of project needs. Matte geomembrane has a strong weather resistance, has a strong anti-aging properties, exposed for a long period of time to maintain the original performance. Nanjing Anti-Sai geomembrane, Edison new materials, special anti-Sai geomembranes new material provided by the Edison Company. Nanjing Anti-Sai geomembrane, Edison new materials, special anti-Sai geomembrane Edison New Materials Co.
