Note the necessary details:

Surface sandblasting machine powder recovery and reuse:

The powder adsorbed on the surface of the profile is only about 1/3 of the powder of all the spray gun, and the powder scattered in the spray room is more. The recovery powder should be mixed with the new powder in the appropriate proportion, and the effect is better, so the powder of the recovery sandblasting machine should be immediately recycled and reused.

Closure of the spray room:

Powder is easy to be polluted by the external air suspended matter, powder spray profile surface is easy to produce fumes and shrinkage holes, after baking affect the profile surface flatness, so the spray chamber should take closed measures to prevent the invasion of pollutants.

The residual powder in the tube should be cleaned immediately. If it is not used for a long time, it is easy to agglomerate. The powder is easy to spit powder, which affects the coating effect.

Standby powder barrel:

In order to replace the powder to use, can effectively improve labor efficiency, must do a good job in the preparation of dustproof, moisture-proof and other maintenance, to ensure the quality of the remaining powder in the barrel.

In addition, filling powder work should also pay attention to:

All technical parameters are adjusted before normal production, but the workpiece must be constantly monitored through the powder supplement window, and the powder should be added immediately if the powder is shallow and does not adsorb the powder. The amount of powder ejected by the manual friction gun is greater than that of the automatic gun, and the manual friction gun can properly accelerate the speed of manual swing. The sandblasting pressure should be maintained at 0.5MPa during sandblasting operation. After using the low-pressure sand blasting technology, there is no residual coating, oil, dirt oxide on the surface of the mold. Finally, the mold is blown dry with compressed air in the equipment.

Type sandblasting machine operation needs to pay attention to the details.

Due to the impact and cutting effect of abrasive on the workpiece surface, the workpiece surface gets a certain degree of cleanliness and different roughness, and improves the mechanical properties of the workpiece surface.
