Second, the sand blasting process is driven by compressed air to form a high-speed jet beam, which sprays materials to the surface of the workpiece to be processed at high speed, so that the appearance of the outer surface of the workpiece changes. Due to the impact and cutting action of abrasive on the workpiece surface, the workpiece surface has a certain cleanliness and different roughness, and the mechanical properties of the workpiece surface are improved.
Third, the operating procedures:
1, you must wear protective equipment before work, and you are not allowed to work with bare arms. There shall be no less than two people at work.
2, gas storage tank, pressure gauge, safety valve to check regularly. The gas storage tank discharges ash every two weeks, and the filter in the sand tank is checked once a month.
3, check the ventilation pipe and sandblasting machine door is sealed. Five minutes before work, ventilation and dust removal equipment must be started. When the ventilation and dust removal equipment fails, the sandblasting machine is prohibited from working.
4, compressed air valve to open slowly, air pressure is not allowed to exceed 0.8MPa.
5. The grit size of sandblasting should meet the working requirements, generally between 10-20, and the sand should be kept dry.
6, sandblasting machine work, prohibit irrelevant personnel near. Please stop the machine when cleaning and adjusting the moving parts.
7, are not allowed to use compressed air to blow dust or joking.
8, after the work, ventilation and dust removal equipment should continue to run for five minutes and then shut down to discharge indoor dust and keep the site clean.
9, personal and equipment accidents, should protect the scene, and report to the relevant departments.
Scope of application: such as steel ring factory, children's seat factory, walker factory, stroller factory, etc.
