Sand Blasting Boron Carbide B4c Sandblasting Venturi Blast Nozzle with Excellent Wear-Resistance

High Quality Boron Carbide Powder (B4C) with Mohs Hardness 9.36

Boron Carbide Powder (B4C) a black crystal powder, is one of the hardest Man-Made materials, its hardness with Mohs hardness 9.36 and microscopic hardness 5400-6300kg/mm2 is only near upon diamond, its density is 2.52g/cm3 and melting point is 2450ºC, The boron carbide possesses properties of endurance hi/low temperature, no reaction with either acids or alkalis, high grinding efficiency, no magnetism. It is a good replacement of diamond. Boron carbide also possesses the special properties of light quality, neutron absorbing, semi-conductivity, etc., so it is used for armed forces and nuclear industry.

Boron carbide is widely applied as follows: boriding refractory, ion transfusion, film layer as well as grinding, polishing, lapping, drilling hard metal alloys, sapphire, jewels, etc. Meanwhile, it is main material for the wear-resisting parts, precise meter-age element, sandblasting nozzle, precise spray nozzle, sealed washer, smelting boron steel, boron alloy, etc.

venturi nozzle

Venturi nozzle has the structure with the converging section, straight section and diffuser section. Compared with the straight hole nozzle, it has better function of gas dynamics, strong improvement in vortex, less pressure loss. Under same pressure, the exit velocity of sandblasting meterials almost doubles as the speed of voice, resulting in higher momentum of the abrasives, increased impact energy and added effectiveness of cleaning.

The service life of Boron Carbide Nozzle is THREE TIMES as Silicon Carbide Nozzles'.

Advantages of our boron carbide nozzle:

Longer service life,High hardness, high wear-resistance ability, anti-corrosion, lower cost per use, reducing down time.
It's the ideal material for sandblasting nozzle and mechanical seal.

Gas Dynamic of venturi nozzle is better than straight-hole nozzle,the vortex is improved or ceased to exist,greatly reduced the pressure loss in the same pressure conditions.Abrasive exports increased to more than double the speed,efficieny than the straight-hole nozzle to increase 15-40%,20% lower abrasive consumption.
