Gas Cleaning Wear Resistant Boron Carbide Ceramic Blasting Nozzle

Ceramic Sand Blasting Nozzle

The B4C tubes are in very high hardness, excellent wear resistance and the boron carbide won’t react with acid-base. High or low temperature resistance, high pressure resistant, density≥2.48g/cm³,micro hardness≥3500kgf/mm², TRS≥400Mpa, melting point is 2450℃

A significant feature of boron carbide ceramics is their high hardness, with a microhardness of approximately 50000 MPa (50 GPa), second only to diamond (90-100 GPa) and CBN (80-90 GPa). Their grinding efficiency can reach 60% -70% of that of diamond, which is twice that of SiC and 1-2 times that of corundum. They have good acid and alkali resistance and a small coefficient of thermal expansion (4.5 x 10-6 ℃), resulting in good thermal stability, but poor impact resistance and high brittleness.

Boron Carbide is one of the hardest man-made materials available in commercial quantities that has a finite melting point low enough to permit its relatively easy fabrication into shapes.

A remarkable feature of boron carbide ceramics is very hard, its hardness is about 50000MPa (that is, 50GPa), second only to diamond (90~ 100GPa) and CBN(80 ~ 90GPa), boron carbide ceramic part can be used as abrasives, cutting tools, wear-resistant parts nozzles, bearings, etc.

The B4C nozzles are in very high hardness, excellent wear resistance and the boron carbide won’t react with acid-base. High or low temperature resistance, high pressure resistant,density≥2.46g/cm³,micro hardness≥3500kgf/mm², TRS≥400Mpa, melting point is 2450℃.With above performance, now many customers choose the boron carbide nozzles to replace the nozzles made from tungsten carbide, silicon carbide, silicon nitride, aluminium oxide, zirconium oxide, etc.

Born Carbide Nozzle

The life time is 10 times longer than ceramic nozzles. They are good for cleaning, even small areas: weldments, grillwork, and railings.
It can be used with water from a tap or with rust inhibitors introduced through any simple pump, no special equipment is required.
If your needed a non-standard nozzle, we also can produce it for you.

boron carbide tube Advantages

(1) Extreme hardness and wear resistance
(2) Exceptional corrosion reistance
(3) Good mechanical strength
(4) Superior anti-oxidation 
(5) Outstanding thermal shock resistance
(6) Low thermal expansion coefficient
(7) High thermal conductivity

Features of boron carbide tubes

1.Long working lifetime: its working lifespan is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.
2. High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity
3. New-style materials: new heat conductivity material ensures faster heat conductivity and pollution-free product, reduces adherent slag.
4. Resistance to corrosion:better anti-corrosion than normal clay-crucible.
5. Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.
6. High-strength: high-density body and logical structure make the product better compression property.
7. Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.

Application: By utilizing the high hardness of boron carbide ceramics, they can be used as abrasives, cutting tools, wear-resistant parts nozzles, bearings, axles, etc. By utilizing its good thermal conductivity, low coefficient of thermal expansion, and ability to absorb thermal neutrons, high-temperature heat exchangers and control agents for nuclear reactors can be manufactured. By utilizing its excellent acid and alkali resistance, chemical vessels, molten metal crucibles, and other materials can be made.

Applications of B4C Ceramic Spray Gun

1. It is applied to agricultural irrigation, changing the traditional irrigation mode, reducing the frequency of equipment replacement and saving costs. 
2. It is applied in spraying. During operations such as phosphating, passivation, and degreasing on the surface of metal parts, it can be used to spray paint on metal parts and can operate in high temperature environments.
