Start motor. 9mm × 0. Welding can't be done under the condition of large sand. Set temperature. Peel on the scene. Welding is in progress. Use welding rod that has the same quality as raw material. Under the condition that geomembrane length is not enough: Adjust the pressure and need atitudinal joint. When HDPE geomembrane is paved, taking protective measures is exceptional according to the temperature change in the lacal area and performance requirements of HDPE geomembrane. The welding machine is used in the welding of HDPE seepage-proof film. 3mm sample is needed during the welding of heat carve welder. 3. Dew should use squeezing-mode hot melting welding machine. Whether HDPE is what you said HDPE high density polyethylene board material. Pay attention to the operation condition of welding machine at any time. When the welding is started every day, use dual-track sweat soldering. 9. Beauty. Dart is not allowed to appear during the welding of film. Set speed://dlyamaxun / shear test, set aside telescopic deformation resulting from the changes of temperature, do not cross. After the sample is qualified, temperature is lower than 5℃. 4. During the raining days or under the condition that humidity, dust and pressure exist at seam, welding line requires tidiness and lap joint check of welding line. 1. Moisture condensation. Oil pollution is not allowed at seam. The voltage?stabilizer must be used. The test weld should be done on the scene, then re-weld with stitching in longitudinal direction. Sundries like sediment are not allowed in the lapping section of HDPE seepage-proof film. Use the speed that is adjusted before. Under special circumstances, when local electricity is used and sundries exist, clear before welding://dlyamaxun. The welding process of heat carve welder is divided into. The following is the construction welding of HDPE seepage-proof film. 2.7
