How to reduce the harm during garnet blasting?
1,The selection of climatic and environmental conditions.There is a certain demand on the atmospheric humidity when blasting on the surface of steel substrate,and it is not suitable to blast during windy day to avoid the dust flying with wind.
(2) Operating of blast nozzle. The spray head first opens the nozzle valve on the surface of the substrate or the ground. When the spray head leaves the matrix, the valve must be closed before the operation is ended. The steel substrate should be placed on the surface and should not be suspended. The spray head is strictly prohibited to spray air or personnel.
(3) waste recycling treatment. The end of the operation must be cleaned in time to avoid the dust at the scene. During the waste transportation, the three oil -proof cloths must be covered to avoid sprinkle or dust. If the sand and rust removal effect.
Garnet sand encounters the metal surface when the metal surface is not crushed. Even after the broken crack, a new corner of the corner -like cube particles will be generated. It is several times that of silicon sand (sea sand or river sand) and quartz sand, and its relative cost is low.
