First, the aluminum frame frame requirements:
1. Common curtain wall profiles, common door and window profiles, and industrial profiles must be installed in the same frame.
2. Heat-insulating curtain wall profiles and insulated door and window profiles must be installed in the same frame.
3. It is not allowed to mix the heat insulation profile with the common profile in the same frame.
4. Each frame shall be filled with a position of 5mm below the frame surface, and each row of profiles shall be separated by a spacer strip to ensure that each profile has a hot air circulation in place to enhance the temperature.
5. Flat model materials with wall thickness ≥ 4 mm are not allowed to overlap (only one is allowed per layer).
6. For the small material with wall thickness ≥ 2mm, 80mm air passage must be left between each frame.
Second, the aging process:
1. Ordinary curtain wall profiles, common door and window profiles, industrial profiles, must be in the same ageing furnace, the furnace temperature is controlled within 195 °C ± 5 °C, after the temperature is reached, the heat is kept for 3 hours, and the blower is blown for 20 minutes immediately after the furnace is discharged. Cool, the quality inspector checks the hardness.
2. Insulation curtain wall profiles, insulated door and window profiles must be in the same ageing furnace, the furnace temperature is controlled within the range of 180 °C ± 3 °C, after the temperature is reached, the furnace is kept for 3 hours, and the fan is blown off for 20 minutes immediately after the furnace is discharged. , quality inspector test hardness
3. If the aging insulation profile is not full, the 1-2 frame ordinary profile (with a wall thickness of 2.0 mm or less) can be placed in the same furnace, and the aging process is carried out according to the heat insulation profile process.
4. When the hanging material is put into the furnace, the profile end and the air guiding port are controlled within 80~100mm.
5. When the temperature in the furnace reaches the required temperature of the process, the aging worker measures the actual temperature in the furnace with a glass tube thermometer every 30 minutes, and makes the original record.
