At present, chemical methods and mechanical processing are usually used to remove rust on the surface of metal or non-metallic surface. Sand blasting machine is a kind of machine which uses compressed air as power to generate high-speed jet beam to spray the spraying material to the surface of the workpiece to be processed, which changes the mechanical properties of the surface layer of the workpiece. The sand blasting machine can achieve full active sand blasting through the electrical control system, which can actively adjust the sandblasting angle, sandblasting time, sandblasting interval, back blowing time, the movement of the spray gun and the rotation speed of the worktable. And mechanical processing is more sandblasting machine.

The sandblasting machine is to use the cryogenic freezing effect of liquid nitrogen to make the rubber plastic alloy data embrittlement. At this time, the burr is embrittled before the product. At the moment when the burr is brittle but the product is not brittle, the sandblasting machine uses a kind of high-speed spray of a high-speed polymer particle to impact the product burr to remove the burr of rubber plastic alloy products and aluminum and zinc alloy products with high quality. In short, the chemical method of acid-base corrosion is to use the cryogenic freezing effect of liquid nitrogen to make rubber plastic alloy materials brittle.

Treatment, there will be a lot of pollution, and it is not easy to control. And machinery can handle this problem easily. Therefore, sand blasting machine and shot blasting machine are widely used in machinery. The power of sand blasting is to extract and shrink air. When processing the same width of the width, the power consumption (refers to the work done by the object in unit time) is large, and the uniformity and gloss error of the processed surface are also large. Shot blasting equipment is an important part of the shot blasting device, which uses the centrifugal casting principle to process the workpiece. It has strict requirements on the shape and data quality of the workpiece, and the equipment is larger when processing the workpiece with the same width.

In contrast, the sandblasting machine adopts the power mode of compressed air, which is more energy-saving and environmental protection. The sandblasting machine is to use the cryogenic freezing effect of liquid nitrogen to make the rubber plastic alloy material embrittlement. At this time, the burr is prior to the product and the product is not brittle. In the time difference between the burr embrittlement and the products without embrittlement, the high-speed spray of a kind of polymer particles to impact the product burr is used to remove the burr of rubber plastic alloy products and aluminum and zinc alloy products with high quality. Not very satisfied with the environment, not very good with the application requirements.
