Gassing film | price of gas membrane building the best choice <> German reputation of thousands of customers choice, 15 years victorious Chinese! Materials testing a membrane structure, membrane structure before making the membrane material must be used and accessories by design and process requirements for testing. Second, the test object should include the following materials and components: membranes, cable, hardware, sewing thread class. Third, the inspection should include: visual inspection, dimensional inspection, material check. Fourth, the test method: test trial quality books and materials provided by suppliers performance tables; by bulk sampling retest. Mechanical properties of membranes reinspection per roll membrane, a sample of projects for each reinspection groups of three specimens. Crop and node III film for one, should be verified before cutting production batch of membranes, pre-qualified certificates and related reinspection compliance report. The body of the same monomer film structure is preferable to use the same batch production of membranes. Second, cutting the design software provides a cutting pattern should be adjusted according to test results after material designed consent. Third, cut the diaphragm, should avoid raw scars woven membranes, knuckles and other significant defects. Fourth, in the cutting operation, fold bending phenomenon may not occur. Fifth, the membrane overlap order shall be determined according to building beautiful, drainage, patch requirements of the connection. Sixth, the cutting operation should be strictly in accordance with crop cutting diagram. The combined film cutting and splicing film after the child should be tested separately and numbered, made a detailed record size, location, and other observed deviations. Seven mosaic membrane seams should ensure the strength requirements, water requirements. Eight, thermal fusion splice should determine the thermal fusion temperature, but also to avoid overheating burns, and strictly control the heat shrinkage distortion occurring fusion to ensure the diaphragm, the film-formation depending on the membrane type. Nine, during heat fusion process, should not allow dust, garbage and dirt buildup on the film material. Ten, thermal fusion process, heat fusion unit may not appear obvious uneven thickness. XI, hot fusion work in the heat fusion temperature, pressure and thermal fusion heat fusion time, should set a good standard value based debugging process design and equipment. XII should be done sewing sewing width, etc. a needle pieces. Non-occurrence skip stitch, off-line and so on. While avoiding distortions caused sewing diaphragm, wrinkles and other phenomena. Thirteen, resettlement affiliated members should properly installed according to the drawings and crop size and so on. Opening fixture opening should not be curly, skew and so on. Playing buttonhole, not a loss, crack. Fourth, there are special requirements diaphragm connection may be considered processed on the spot, and to develop appropriate technology requirements to ensure quality. www.zdmjg.com
