The Effect of Welding Process of VIP Blocking Membrane on Its Heat Sealing Strength and Microstructure

摘要：

　　Based on the blocking membrane PA/VMPET/A1/PE of vacuum insulation panel,heat sealing is carried out with different parameters including temperature,time and pressure.Combining with the test of heat sealing strength of blocking membrane,the welding parameters are optimized.Through the analysis of microstructure of films,the effect of various technology factors on heat sealing quality is investigated.Some ways are suggested to improve the heat sealing strength,which makes the blocking membrane welded well.
