Take you to understand the classification of sand blasting gun
Tungsten steel blasting gun is suitable for general blasting. It is suitable for most open blasting and blasting rooms. Tungsten steel blasting gun is composed of hard tungsten carbide lining, nylon and polyurethane shell. The housing is equipped with 50mm (2 ") threads, which can be easily connected to or removed from the nozzle sleeve, and there is no problem of sand jamming that often occurs with fine-threaded nozzles.
Tungsten steel blasting gun has high durability, it is suitable for working environments where rough work may occur and brittle nozzles are easily damaged. Venturi design of nozzles and air supply ensure maximum efficiency.
Boron Carbide Blast Gun
The main raw material of boron carbide 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. , 36, micro hardness of 5400-6300 kg per square meter, density of 2.52 kg per square meter, melting point of 2450 degrees Celsius, boron carbide is hexagonal dark black.
Features of boron carbide products: it has the same performance as boron carbide, is extremely hard and wear-resistant, does not react with acids and bases, and is resistant to high, low, and high pressure, with 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. The life of the high-speed secondary air inlet sand blasting nozzle produced by our company can reach 1,000 hours, and the inner diameter of the nozzle wears 1-2 mm.
