[China Aluminum Industry Network] First, aluminum frame mounting requirements:
1. General curtain wall profiles, general door and window profiles, industrial profiles, and the need to be installed in the same frame.
2. Insulation curtain wall profiles, insulated doors and windows profiles, it is necessary to be installed in the same frame.
3. It is not allowed to mix insulation profiles with general profiles in the same frame.
4. It is necessary to fill the frame with the following 5mm orientation for each framed section, and each row of profile must be separated by a pad to ensure that each section has a hot air circulation function to play a role in heating.
5. Flat model materials with wall thickness â‰¥ 4mm are not allowed to be stacked (only one per layer is allowed).
6. It is necessary to leave 80mm air ducts in the center of the box for small materials with wall thickness â‰¥ 2mm.
Second, aging technology:
1. General curtain wall profiles, general door and window profiles, industrial profiles, and the same time aging in an aging furnace, furnace temperature control in the 195 Â°C Â± 5 Â°C range, reach the temperature after 3 hours of heat release, immediately after opening the fan blowing 20 Minutes of cooling, quality inspectors check the hardness.
2. Insulation curtain wall profiles, heat insulation doors and windows profiles, it is necessary with a aging furnace aging, furnace temperature control in the 180 Â°C Â± 3 Â°C range, reach the temperature after 3 hours of heat release, immediately after opening the fan blow 20 minutes Cooling, quality inspectors check the hardness
3. If the aging insulation profile is less than the furnace, it can put 1 to 2 frame general profiles (thickness less than 2.0mm) with the aging of the furnace, aging technology according to insulation profile technology.
4. When the material is loaded into the furnace, the end of the profile and the air inlet are controlled within 80-100mm.
5. When the temperature in the furnace reaches the technical demand temperature, the aging worker measures the practical temperature in the furnace with a glass tube thermometer every 30 minutes and makes the original records.
