[China Aluminum Industry Network] The production process of heat-insulating profiles is simply based on the original aluminum extrusion and surface treatment, and a rolling and compounding process for insulation bars is added. For the production of aluminum profiles and the control of processing processes, all professionals have accumulated rich practical experience. Here we only discuss the common problems encountered by the majority of aluminum production enterprises in the process of heat insulation profiles in combination with “insulation profiles. 》 GB5237.6 in the heat insulation section proposed some of the quality requirements to do a relevant explanation, one-sided place to invite the majority of industry leaders, colleagues criticism. Here mainly involves the discussion of four aspects:
• Longitudinal shear performance of insulation profiles at room temperature;
• Longitudinal shear resistance at high temperature of the insulation profile;
• Powder coating cracking on the outer surface of the outer jaw of the insulation profile;
• The dimensional accuracy control of the insulation profile.
