Several Problems Should Be Paid Attention To In Aluminum Alloy Spraying Operation - China

Several problems should be paid attention to in aluminum alloy spraying operation

The selection of fixture production and feeding method.

The clamps hung at both ends should ensure that they can withstand considerable pressure; the clamps used in the middle part should be made and used as far as possible to minimize the size of the contact points between the clamp and the outer surface of the profile, and the vertical suspension in the middle should be timely adjusted Replenish powder on the rod.

The hanging position in the hanger of aluminum alloy profile should also follow the corresponding principle.

For some profiles with deep grooves, increasing the amount of powder and pushing the distance between the spray claw and the profile are applicable; surfaces with large surface areas or complex structures should not be placed in a downward position, and the decoration of the profiles should also be distinguished Noodles and non-decorative noodles.

For some aluminum alloy profiles with special shapes, adjust the position of the fixture in time to keep the aluminum alloy profile at a certain angle of inclination at the position of the hanger to enhance the stability during operation and facilitate powder adsorption.

In addition, for some heavier profiles, when using the clamp in the middle position, the elbow part should have a certain curvature.

The curvature of the clamp can ensure that the aluminum alloy profile is in a vertical position and ensure a smooth production process.

In addition, conductive beams and hangers will accumulate more and more coating film as the number of cycles increases.

The coating film itself is non-conductive, which will affect the conductivity of the conductive beam and the hanger, and further affect the uniform distribution of the powder on the surface of the aluminum alloy profile.

The coating film on the conductive beam and the hanger should be removed in an appropriate way.

The pre-treatment process is simpler than the ordinary pre-oxidation process, mainly degreasing and chromization, the consumption of raw materials is lower, and the routine maintenance is relatively easy.

In order to improve production efficiency and reduce energy consumption during the pre-treatment process, larger racks are often used and as many profiles to be processed as possible are installed.

For some softer aluminum alloy profiles, the crossbar should be placed in the middle of the aluminum alloy profile, and the groove part should be placed as far as possible to facilitate the evaporation of water.

After the drying process, when there is still moisture remaining, in order to avoid damage to the aluminum alloy profile surface and the profile is prone to deformation when the temperature is too high, it should not be put into the furnace for baking.

Use an air gun (no oil and gas) to blow dry.

In addition, the profile must maintain a proper inclination angle during the dripping and drying process, but it is easy to cause part of the profile to slip off.

A piece of stainless steel wire mesh should be tied to one end of the rack as a preventive measure.

Issues that should be paid attention to in the spray booth: Before the formal spraying, you can try spraying several times.

At this time, you can observe the size of the powder amount and the uniformity of the powder distribution at both ends of the spray booth.

The powder at this time runs in a straight line within 10cm from the tip of the spray claw, and the outside part is in the form of atomized powder.

The powder adsorbed on the surface of the profile is actually the powder with this atomization effect.

Does this atomization exist? The effect of powder is used as a standard for controlling the distance between the spray claw and the profile.
