Open sandblasting machine is a direct pressure sandblasting machine. With the help of the power, flow rate and flow rate of compressed air, various abrasives are sprayed onto the metal surface. The abrasives sprayed on the metal surface are subjected to impact grinding on the metal surface to remove the impurities and oxide scales on the surface, so as to increase the surface area, improve the adhesion of the coating, improve the coating quality, and remove the internal participation in the structure power.
The open sandblasting machine is divided into two categories: general pressure open sandblasting machine and pressurized open sandblasting machine. The working principle of general pressure open sand blasting machine is similar to that of suction dry sand blasting machine. It is driven by compressed air, through the negative pressure formed in the spray gun by the high-speed movement of the air flow, the abrasive is sucked into the spray gun through the sand conveying pipe, and then accelerated by the compressed air, the abrasive is ejected from the nozzle and sprayed to the machined surface to achieve the expected processing purpose. In the suction dry sand blasting machine, compressed air is not only the feeding power but also the accelerating power of jet.
The working principle of the pressurized open sandblasting machine is similar to that of the press in dry sandblasting machine. The abrasive is compressed into the sand tank by compressed air, and then compressed air is injected into the surface of the sand tank to compress the air, and then the air is injected into the sand tank to compress the air. In the press in dry sand blasting machine, compressed air is not only the feeding power but also the accelerating power of jet. The pressurized open sand blasting machine adopts the pressure feeding sand blasting (shot blasting) mechanism, that is, the high pressure effect is formed by the high-speed flow of compressed air in the high-pressure tank, and the sand material in the high-pressure tank is pressed into the sand regulating valve. At the same time, another way of compressed air flow also enters the sand control valve, and accelerates the sand material entering the sand control valve, so that the sand material is ejected through the sand conveying pipe, and then with the compressed air flow, it is sprayed to the surface of the workpiece with high speed from the spray gun nozzle, so as to achieve the purpose of sand blasting processing and cleaning the surface of metal and non-metallic work pieces.
When the open sandblasting machine is working, the compressed air and abrasive in the container are mixed and sprayed, so that the compressed air can be fully utilized, the air flow and abrasive flow can be easily adjusted, the ideal mixing ratio can be obtained, the energy and abrasive consumption is low, and the research and sweeping efficiency is high. It is suitable for the metal surface of shipbuilding, aircraft, locomotive, machinery, bridge, chemical industry and other industries Large area cleaning and derusting. The equipment and compressed air are the main equipment for cleaning and derusting the metal surface

Application range:
1、 Pretreatment: sandblasting treatment before plating, painting, spraying and other covered processing, the surface is absolutely clean, and greatly improves the adhesion and anti-corrosion ability of the coating.
2. Cleaning: remove oxide scale, residue and dirt from metal workpieces such as casting parts, stamping parts, welding parts and heat treatment parts; clean the surface of non-metallic products, remove black spots on the surface of ceramic embryo parts and reduce the paint pattern.
3. Core Renovation: renovation and cleaning of all moving parts such as automobiles, motorcycles, electromechanical equipment, etc. At the same time, the fatigue stress is eliminated and the service life is prolonged.
All metal products and non-metallic products (plastic, crystal, glass, etc.) surface trace elimination, argon fog surface treatment, so that the product surface upgrade grade.
5. Mold treatment: argon mist surface treatment of mold surface, graphic production, and mold cleaning, which will not damage the mold surface and ensure the mold accuracy.
6. The micro burr of the parts processed by the burr processor is removed, and the rubber overflow and burr of the injection molding parts are eliminated.
7. Rework of defective products: removal of defective covering layer, surface coloring and printing.
8. Strengthen the surface hardness of metal parts and relieve stress, such as surface treatment of aircraft blades, springs, machining tools and weapons.
9. Anti skid etching processing: etched patterns, characters and anti-skid treatment on the surface of metal products and non-metallic products, such as marble, handle anti-skid, seal, stone inscription, etc. Denim sanding, whitening and cat hair effect.
