Raw materials and characteristics of sand blasting gun


Boron carbide, the main raw material of sand blasting gun, is one of the hardest man-made materials. It has the characteristics of light weight, semiconductor properties, neutron absorption, high grinding efficiency, and does not react with strong acids and alkalis. Mohs hardness is 9,36. , Micro hardness is 5400 ~ 6300 kg per square meter, density is 2.52 kg per square meter, melting point is 2450 degrees Celsius, boron carbide is hexagonal dark black.
Sandblasting boron carbide product features: It has the same properties as boron carbide, is extremely hard and wear-resistant, does not react with acids and alkalis, is resistant to high and low temperature and high pressure, and has a density ≥ 2.46 g / cm3. Micro hardness ≥3500kgf / mm2, flexural strength ≥400Mpa, melting point 2450 ℃. Boron carbide sandblasting nozzles can replace the known cemented carbide and silicon carbide, silicon nitride, alumina, zirconia and other materials.
