Our factory provides sand blasting rust removing corundum, sand blasting rust removal is made of quartz sand, petroleum coke (or coal coke), wood chips as raw materials through the resistance furnace high temperature smelting. Silicon carbide also has a rare mineral, Moissanite, in nature. Emery is also called garnet. Among the non-oxide high-tech refractory materials such as contemporary C, N, and B, silicon carbide is the most widely used and most economical one. It can be called grit or refractory sand. Silicon carbide is made of quartz sand, petroleum coke (or coal coke), wood chips (need to add salt when producing green silicon carbide) and other raw materials in the resistance furnace by high-temperature smelting. Emery is ranked 9th in the Mohs hardness scale. The specific gravity is 4.00 with a hexagonal columnar lattice structure. Because of the hardness of corundum and its relatively cheap price compared to diamonds, it becomes a good material for sandpaper and grinding tools.
Compressed air is used as a motive force to form a high-speed jet beam to spray the material (garnet sand, copper ore, quartz sand, corundum, iron sand, Hainan sand) to the surface of the workpiece to be processed at a high speed to make the outer surface of the workpiece surface. The appearance or shape changes, due to the impact of the abrasive on the workpiece surface and the cutting action, so that the surface of the workpiece has a certain degree of cleanliness and different roughness, so that the mechanical properties of the workpiece surface are improved, thus improving the fatigue resistance of the workpiece. The adhesion between the coating and the coating is increased, the durability of the coating is prolonged, and the leveling and decoration of the coating are also facilitated.
The main application scope of sandblasting is edited. (1) Workpiece coating and sandblasting before workpiece bonding can remove all dirt and other dirt on the surface of the workpiece, and establish a very important basic pattern on the surface of the workpiece. The rough surface), and can be exchanged through different sizes of abrasives, such as fly abrasive abrasive abrasive to different degrees of roughness, greatly improve the binding of the workpiece and the coating, plating material. Or make the adhesive bond more firm and better quality.
The sandblasting process pretreatment stage refers to the treatment of the workpiece surface before the workpiece is sprayed or sprayed with a protective layer. The sandblasting process uses compressed air as the motive force to form a high-speed jet beam, and sprays the material at high speed to the surface of the workpiece to be processed, so that the appearance of the workpiece surface changes, and the surface of the workpiece is obtained due to the impact of the abrasive on the workpiece surface and the cutting action. A certain degree of cleanliness and different roughness make the mechanical properties of the workpiece surface improve.
The quality of the sandblasting process before treatment affects the adhesion, appearance, moisture resistance and corrosion resistance of the coating. The pre-treatment work is not good, and the corrosion will continue to spread under the coating, causing the coating to fall off. After careful cleaning of the surface and the general simple cleaning of the workpiece, compared with the exposure coating, the life can be 4-5 times the difference. There are many methods for surface cleaning, but the most commonly accepted methods are: solvent cleaning, pickling, hand tools, and power tools.
Grinding and polishing sandblasting of the matte surface of the casting and the heat treated workpiece can clean up all the dirt (such as oxide skin, oil and other residues) on the surface of the casting and forging and the heat treated workpiece, and polish the surface of the workpiece to improve the finish of the workpiece. The workpiece shows a uniform metal color, making the appearance of the workpiece more beautiful and beautiful.
The burr cleaning and surface beautification of the machined parts can clean up the tiny burrs on the surface of the workpiece and make the surface of the workpiece smoother, eliminating the danger of burrs and improving the grade of the workpiece. And sandblasting can make a small round at the interface of the workpiece surface, making the workpiece more beautiful and more precise. Improve Mechanical Properties of Parts After sandblasting mechanical parts, it can produce uniform and fine concave and convex surfaces on the surface of the parts, so that the lubricating oil can be stored, thereby improving the lubrication conditions, reducing the noise and improving the service life of the machinery.
Polishing effect For some special-purpose workpieces, sandblasting can be used to achieve different reflective or matte finishes. Such as stainless steel workpieces, plastic grinding, polishing jade, wooden furniture surface matt, frosted glass surface pattern, as well as the fabric surface of the wool processing. Matters to pay attention to when working in sand 1. Before you work, you must wear protective equipment and do not allow naked arms to work. There must be no less than two people at work. Gas tanks, pressure gauges, and safety valves are regularly checked. Gas tanks emit dust once in two weeks, and the filters in the tanks are checked once a month. Check that the vent pipe and blast door are sealed. Five minutes before the work, ventilation and dust removal equipment shall be activated. When the ventilation and dust removal equipment fails, the sand blasting machine is prohibited to work. The compressed air valve should be opened slowly and the pressure should not exceed 0.8 MPa. Sandblasting particle size should be compatible with the work requirements, generally apply between the 10th and the 20th, sand should be kept dry. When the sandblasting machine is working, it is forbidden that the unrelated person is approaching. When cleaning and adjusting the operating position, it should be stopped.

1. General composition A complete inhalation dry sandblasting machine generally consists of six systems, namely the structural system, the media power system, the pipeline system, the dust removal system, the control system and the auxiliary system.
2. Working principle Inhalation dry sand blasting machine is powered by compressed air, and the negative pressure formed in the spray gun through the high-speed movement of air flow. The abrasive is passed through the sand conveying pipe.
The spray gun is sucked and ejected through the nozzle and sprayed onto the surface to be processed to achieve the desired processing target. In the suction type dry blasting machine, compressed air is available.
Press-in Dry Sandblasting Machine 1. Generally, a complete press-in dry sandblasting machine working unit is generally composed of four systems, namely pressure tank, medium power system, pipeline system and control system.
2. The principle of press-in dry sandblasting machine.
Press-in type dry blasting machine is powered by compressed air, and the working pressure created by the compressed air in the pressure tank passes the abrasive through the sand outlet valve.
It is pressed into the sand delivery pipe and ejected through the nozzle. It is sprayed onto the machined surface to achieve the desired processing target. In press-in dry sand blasting, compressed air is used for both.
