What Is a Sandblasting Enclosure?

Sand blasting abrasive has the characteristics of short grinding time, high efficiency, good efficiency, and low price; moderate hardness, high toughness, good self-sharpening, low sand consumption and can be recycled and reused, and the smoothness of the abrasive is good; Grinding, acid and alkali resistance. Sandblasted abrasive shell-shaped fracture, sharp edges and corners, can form new edges and edges in the continuous crushing and classification, making its grinding ability better than other abrasives. In particular, it has the advantages of high hardness, high specific gravity, stable chemical properties, and its unique self-sharpness. It has become the first choice for abrasives for sand blasting processes; at the same time, it is an ideal material for sand blasting and rust cleaning of workpieces and grinding and polishing.

Blasting abrasive

Blasting abrasives use compressed air as the power to form a high-speed spray beam to spray the blasting materials (garnet, copper ore, quartz sand, corundum, iron sand, Hainan sand) at high speed on the surface of the workpiece to be treated, The appearance or shape of the surface changes. Due to the impact and cutting action of the abrasive on the surface of the workpiece, the surface of the workpiece has a certain degree of cleanliness and different roughness, and the mechanical properties of the surface of the workpiece are improved, so the fatigue resistance of the workpiece is improved. It increases the adhesion between it and the coating, prolongs the durability of the coating film, and is also conducive to the leveling and decoration of the coating.

Generally divided into artificial abrasives and natural abrasives:

Silicon carbide (SiC) is an artificial abrasive and is used

1. Protective equipment must be worn before work. Bare arms are not allowed to work. No less than two people at work.

2. The gas storage tank, pressure gauge and safety valve should be checked regularly. Dust is discharged from the gas storage tank once every two weeks, and the filter in the sand tank is checked once a month.

3. Check whether the ventilation pipe and the blast door are sealed. Five minutes before work, the ventilation and dust removal equipment must be started. When the ventilation and dust removal equipment fails, the sand blasting machine is prohibited to work.

4. The compressed air valve should be opened slowly, and the air pressure must not exceed 0.8MPa.

5. The particle size of the sand blasting should be compatible with the requirements of the work, generally between 10 and 20, and the sand should be kept dry.

6. When the blasting machine is working, it is forbidden to approach unrelated personnel. When cleaning and adjusting the running parts, stop the machine.

7. Do not use compressed air to blow dust or make jokes on your body.

8. After work, the ventilation and dust removal equipment should continue to run for five minutes and then shut down to exhaust indoor dust and keep the site clean.

9. Personal and equipment accidents should be maintained on-site and reported to relevant departments.
