How to avoid unsafe problems in the use of sand blasting equipment

Safety problems of sand blasting equipment in use and how to avoid these unsafe problems. First, check the joints of the sand blasting machine. All joints of the sand blasting equipment (air pipe, gauze pipe interface, etc.) must be firmly installed and reliably connected. In the process of operation, the wear condition of air pipe and gauze tube should also be checked frequently. If there is serious wear condition, it must be replaced immediately. Then there is the need not to face people in the process of operation. Dalian sand blasting

In addition, when repairing the sand blasting equipment, be sure to stop the machine, release the air, and then open the cover. Operators must wear sandblasting clothes, sandblasting headgear and sandblasting gloves during the process to prevent the accidental damage of sand particles sprayed by high-pressure air flow. Other small details should also be paid attention to, that is, after sandblasting, we must clean up the scattered sand materials and sand particles on the ground to prevent slipping and falling.

Pressure sandblasting machine uses compressed air flow to spray quartz sand on the surface of stainless steel parts to clean or modify the surface. That is to remove the oxide scale on the surface of stainless steel castings, forgings or after heat treatment. At the same time, it can also remove the rust, carbon deposit, welding slag and other sundries on the surface. It can also remove the edge burrs and some slight directional scratches of parts. It can also improve the surface roughness of stainless steel parts, so as to improve the adhesion of the rear surface coating.

Before dry sand blasting, the stainless steel must be degreased and then dried to avoid affecting the sand blasting quality, and then the appropriate sand particles and air pressure shall be selected according to the thickness of the parts. The wet spraying method of pressure sandblasting machine is to mix quartz sand and water into mortar, add sodium nitrite if necessary, and then spray it on the surface of parts with compressed air. Compared with dry sand blasting, it eliminates the air pollution caused by sand dust, and the processed surface is also relatively fine. Dalian sand blasting outsourcing service

Quartz sand blasting uses compressed air as power to form a high-speed jet beam to spray the sprayed materials (copper ore, quartz sand, emery, iron sand and Hainan sand) to the workpiece surface to be treated at high speed, so as to change the appearance or shape of the outer surface of the workpiece surface. Due to the impact and cutting effect of the grinding materials on the workpiece surface, the workpiece surface can obtain certain cleanliness and different roughness, The mechanical properties of the workpiece surface are improved, so the fatigue resistance of the workpiece is improved, the adhesion between it and the coating is increased, the durability of the coating film is prolonged, and it is also conducive to the leveling and decoration of the coating.
