How to derust the surface of sandblasting gun


How to derust the surface of sandblasting gun :

Manual or power tools should be used to remove rust on the parts that the sandblasting gun cannot spray.
I. Sand blasting abrasive control The sand used for sand blasting and rust removal is compared with the pre-blasting. Quartz sand and river sand are mixed with 1: 1 for best rust removal effect.
2. When the blasting gun controls the blasting operation, understand the nozzle wear. When the diameter of the orifice increases by 25%, the nozzle should be replaced.
