1. When the material is hoisted into the furnace, the end of industrial aluminum profile and the air guide are controlled within 80 ~ 100mm.

2. The aluminum profile of heat-insulated curtain wall and the profile of heat-insulated point window must be aged in the same aging furnace, and the temperature in the furnace should be controlled within the range of 180℃ 3℃. After reaching the temperature, they should be kept warm for 3 hours and discharged from the furnace. Immediately after being discharged from the furnace, the fan should be turned on to blow for 20 minutes to cool down, and the quality inspector should check the hardness.

3. It is not allowed to mix thermal insulation profiles with ordinary profiles in the confrontation frame.

4. Aluminum profiles for heat insulation curtain walls must be divided into frames.

5. Small materials with a wall thickness of 2 mm or more must have 80mm ventilation ducts at both ends of each box.

6. If the aging heat insulation profile doesn't like the furnace, probably put 1 ~ 2 frames of mediocre profile (the wall thickness is below 2.0mm).

7. Ordinary curtain wall profiles and ordinary door and window profiles must be aged in the same aging furnace, and the temperature in the furnace should be controlled within the range of 195℃ plus or minus 5℃. After reaching the temperature, they should be kept warm for 3 hours, and immediately after being discharged, the fan should be turned on to cool for 20 minutes, and the quality inspector should test the hardness.

8. Flat formwork materials with a wall thickness of ≥4mm are not allowed to be stacked (only one is allowed per layer).

9. When the temperature in the furnace reaches the required temperature, the aging worker will measure the experimental temperature in the furnace with a glass tube thermometer every 30 minutes, and make original records.

10. Ordinary curtain wall aluminum profiles, ordinary doors and windows profiles, and building profiles must be packed separately in the counter frame.

The advantages and disadvantages of various connectors for industrial aluminum profiles are introduced.

Industrial aluminum profile is an alloy material with aluminum as the main component. Aluminum bars can be obtained with different cross-sectional shapes by hot melting and extrusion. However, the mechanical properties and application fields of industrial aluminum profiles are different with different proportions of added alloys.

The connection of industrial aluminum profiles is mainly realized by connectors, and the modular installation method is simple and strong. There are many kinds of connectors used in industrial aluminum profiles, including angle pieces, built-in connectors, anchor connecting pins, hexagon socket bolts, connecting plates and so on.

1. Corner pieces

The advantage is that it is convenient to install, the profile does not need to be punched, and it can be fixed directly on the profile groove with bolts and nuts. Moreover, the types of corner pieces, including right-angle pieces, machined corner brackets, 45-degree corner pieces, 135-degree corner pieces, etc., can realize T-shaped, L-shaped and cross-shaped connection of profiles, can be used in many frame structures, and have high connection strength and long service life.

The disadvantage is that it is not beautiful enough and belongs to the external connector, and sometimes the corner piece will occupy the space in the profile groove, which is not convenient for the installation of the plate.

2, built-in connectors

The advantage is that it is beautiful, hidden inside the profile, and can realize cross or right-angle connection of the profile.

The disadvantage is that the connection strength is not so good, so it can be applied to light frame structure, and pay attention to its installation method, because the built-in connector will also occupy the space in the profile groove, so you must pay attention to its installation position when installing the plate.

3, the anchor connection is slightly

The advantages are similar to those of the built-in connector, which also belongs to the internal connector, so the aesthetic degree is better. Moreover, the anchor connecting pin is not divided into national standard or European standard, as long as the corresponding one is selected according to the groove width of the profile.

The disadvantage is that it can only be used on the profile of groove 8 or groove 10, and other groove widths cannot be used.

4. Hexagon socket bolts

The advantages are high connection strength, belonging to the internal connector, beautiful and firm, realizing the right-angle connection of two or three profiles, and not affecting the installation of plates, and the application range is wide. I don't know which connection mode to choose, so it is right to choose the hexagon socket bolt.

The disadvantage is that it needs to be punched in advance and the construction period is longer.

5. Connecting plate

The advantages are similar to those of corner pieces. There is no need to punch holes in the profile, but it can be fixed directly on the profile groove with bolts and nuts.

The disadvantage is that it is not beautiful enough, and the connection strength is not as good as that of corner pieces.
