Sand blasting process description of wet sand blasting machine
Wet sand blasting machine sand blasting process:
The principle of a wet sandblasting machine is very simple. Driven by compressed air, a high-speed jet beam is formed to spray the shot peening onto the workpiece surface at a high speed, which changes the mechanical properties of the outer surface of the workpiece surface. Due to the impact and cutting of abrasive on the workpiece surface, the workpiece surface can obtain a certain degree of cleanliness and different roughness, and can improve the mechanical properties of the workpiece surface. Therefore, improve the fatigue resistance of the workpiece, increase the adhesion between the workpiece and the coating, prolong the durability of the coating, but also conducive to the smooth and decoration of the coating, remove the impurities, noise and oxide layer on the surface, rough the surface of the medium, generate residual stress on the surface of the substrate, improve the surface hardness of the substrate.
Maybe you don't understand the terms. Let me give you a simple example. There are many strange shapes of stones in the desert. Some stones have a smooth surface and round holes in the center or somewhere. That's how sandblasting works, by the way. It is the high speed of the wind mixed with the sand that makes the stones smooth. But over time, holes will appear where the stone is relatively weak. Once a hole forms, it gets bigger and bigger; The effect is amplified. High pressure compressed air is used to blow denser, sharper sand towards the workpiece. It is a new technology to treat oxide on metal surface with wet sand blasting machine in recent years. It not only ejects oxides from the metal surface, but also creates many small holes in the metal surface. These holes will make the paint or subsequent coating stickier and last longer,
If only the quality of the process is compared, sandblasting is far better than pickling, but the sandblasting machine also has disadvantages. Sand blasting machine needs manual operation, processing efficiency is not as good as pickling. There are also many wearing parts in the wet sandblasting machine, so more professional operators are needed. The process is simple to operate, single processing capacity is large, no manual operation is required, and no fault. As a result, the process was widely used in manufacturing several years ago, however, wet sandblasting is also a disadvantage. As the volatility of wet sand blasting is a strong gas, operators endure pungent smell, long-term operation will suffer from occupational diseases. Therefore, some enterprises have special provisions for wet sandblasting workers, that is, change their jobs after three to five years of work, or dismiss them for other reasons, to avoid possible disputes in the future; After a period of use, the effectiveness of wet sandblasting will slowly decline. If the wet sandblasting solution needs to be replaced, this means the waste will be discharged somewhere. However, the discharge of old liquid waste is often a troublesome problem. If the wet sandblasting solution needs to be handled by the equipment in the normal way, it is expelled. However, the cost of the equipment needed to handle this very heavy metal content of wet sandblasting liquid is very high, and the operation cost is unaffordable for the average business, so most companies simply discharge into the ground, cheaply but wreaking havoc on the environment. Therefore, the state is also very strict in this regard. This is the disadvantage of the sandblasting machine.
