Blast MachinePowder Recycling

The powder adsorbed on the surface of the profiles by the sandblasting machine only accounts for about 1/3 of the powder output of all the spray guns, and there is a lot of powder scattered in the spray booth. The recovered powder must be mixed with the newly added powder in an appropriate proportion. It is better, so the powder should be recycled and reused in time.

1. Sealing in the spray booth

The powder is easily polluted by the suspended matter in the outside air. After powder spraying, the surface of the profile is prone to flocs or shrinkage holes, which will affect the smoothness of the profile surface after baking. Therefore, the spray booth should be closed to prevent contamination. intrusion.

2. The residual powder in the trachea should be cleaned in time. If it is not used for a long time, it is easy to agglomerate, and the powder is prone to spit powder, which affects the spraying effect.

3. Spare powder bucket

The sandblasting machine is used for powder change, which can effectively improve labor efficiency. The maintenance work such as dustproof and moisture-proof of the spare powder bucket must be done well to ensure the quality of the remaining powder in the powder bucket.

4. In addition, the work of supplementing powder should also be paid attention to

Although various technical parameters have been debugged before normal production, the workpiece should be continuously monitored through the powder replenishment window from time to time, and the powder should be replenished in time when the powder is found to be shallow and the powder is not adsorbed. Since the amount of powder sprayed by the manual friction gun is larger than that of the automatic gun, the swing speed of the manual friction gun can be appropriately accelerated.
