Introduction SiSiC Ceramic Sandblasting Nozzles
Sand blasting is powered by a compressed air or a grinding fluid pump,the abrasive is sprayed through the spray gun at high speed onto the surface of the part for cleaning and polishing. At present, sandblasting technology is widely used in machinery, petroleum, chemical, automotive, marine, aerospace, metallurgy, glass, coal and other industries. The sandblasting nozzle is the main wear-resistant component in the blasting equipment. It can be used with various dry or wet blasting machines. It is one of the key parts of mechanical equipment such as surface strengthening, surface cleaning, surface coating, surface modification and jet cutting.
Characteristics SiSiC Ceramic Sandblasting Nozzles
Many experts and scholars domestic and overseas have done a lot of research on how to improve the life and reliability of nozzles. Can be summarized as:
- Changing the structure of the nozzle, optimizing the nozzle size parameters to improve the nozzle life and reliability;
- The life of the nozzle can be improved from its microstructure;
- The life of the nozzle was studied from the viewpoint of the distance between the nozzle and the sample, the particle size of the abrasive grains, and the angle of the abrasive spray.
Studies have shown that the life of the nozzle is not only closely related to the material, but also restricted by the actual application environment. Under different application conditions, the life span of the nozzle can vary by tens or even hundreds of times. The harsher the working environment of the nozzle, the shorter the life. Materials commonly used to make nozzles include: steel, cast iron, tungsten carbide and ceramic materials. Among the most commonly used ceramic nozzle materials are: Al2O3 based ceramics, SIC ceramics, Si3N4 based ceramics and B4C ceramics.Our company is specializes in producing ceramic sandblasting nozzles for more than 9 years.
