  In order to make the surface treatment reach the standard of cleanliness and roughness, in addition to the use of Steel Grits, there must be a standard process parameter to ensure that the surface treatment is to meet the prescribed cleanliness standard and the standard of roughness.

  To ensure sandblasting quality, new nozzles with new structure should be selected. For example, the use of Steel Grits For Sand Blasting SAE Standard, abrasive injection speed up to 200m/s; and ordinary straight barrel nozzle spray speed is only 97m/s, the difference between the two times 3 times. For the nozzle aperture, under the condition of certain air pressure, the diameter of the nozzle increases, the amount of air loss and sand production increase, and the Steel Grits efficiency is increased. The choice of aperture is restricted by air supply, generally 8~15mm. Due to abrasion, new nozzle should be replaced when the aperture of the steel grit blasting nozzle increases by 25%.
