The industrial aluminum profile workpiece is not thoroughly washed after alkali washing. If the alkali liquor entering the hole during alkali washing is not washed clean, the alkali liquor after oxidation treatment will flow out of the cylinder eye, resulting in corrosion of the oxide film around the hole. There is a movable slope around the eyelet of industrial aluminum profile workpiece. Industrial aluminum profiles are very astringent when tapping the screw holes, and operators often use reactive dyes to lubricate them. If there is a lack of emulsifier in alkaline solution, it is difficult to remove reactive dyes.

The solution to the perforation of industrial aluminum profile: wash it with gasoline before alkali washing, and emulsifier should be added to the alkali washing solution. The workpiece should be rinsed clean after alkali washing.

As we all know, with the development of economy, the use of industrial aluminum profiles is very common. Industrial aluminum profiles play a very important role in the construction industry, and the demand for industrial aluminum profiles in the construction industry is also very large. If the quality of industrial aluminum profiles is not good, it will certainly have a greater impact. Therefore, users must choose the products of well-known industrial aluminum profiles manufacturers when purchasing industrial aluminum profiles, and their product quality will be more guaranteed.

Analysis on the causes of aluminum profile twisting and bending in aluminum profile manufacturers?

Aluminum profile manufacturer aluminum profile refers to aluminum alloy profile. Generally speaking, industrial aluminum profiles refer to all aluminum profiles except those used for building doors and windows, curtain walls, indoor and outdoor decoration and building structures. The wave, twist and bending of aluminum profile are the profile shape defects caused by uneven metal flow. Analysis on the causes of twisting and bending in aluminum profile manufacturers;

Aluminum profile manufacturer

main reason

1. Unreasonable design of working zone of aluminum extrusion die leads to uneven metal flow;

2. The extrusion speed of aluminum profile is too fast or the extrusion temperature is too high, which leads to uneven metal flow;

3. Unreasonable hole layout of aluminum alloy lattice die causes uneven metal flow;

4, the guide is not suitable or not installed;

5. Improper lubrication.

solution

1. Trim the working zone of aluminum extrusion die to make metal flow evenly;

2. Adopt reasonable extrusion technology and try to adopt low temperature extrusion under the premise of ensuring the outlet temperature;

3. Reasonable design of aluminum extrusion die structure;

4, configure the appropriate guide;

5. Reasonable lubrication;

6, using aluminum extrusion tractor traction extrusion.

What are the requirements for aging framing operation of industrial aluminum profiles?

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.
