Dongguan Meijun: Single-inlet sandblasting gun (Class A hot-pressed sintered pure boron carbide)
Single-inlet boron carbide sandblasting gun, venturi sandblasting gun, long-range sandblasting gun, pressure sandblasting gun

Single air blasting gun alias: Venturi nozzle: (Venturi nozzle, English Venturi Nozzle)

The structure of the venturi sandblasting nozzle is divided into three parts: contraction section, straight section and diffusion section, which is difficult to manufacture. The aerodynamic performance of the venturi nozzle is better than that of the straight hole nozzle, the vortex phenomenon is significantly improved or no   exists, and the pressure loss is greatly reduced. The outlet speed of the abrasive can be more than doubled, the working efficiency is 15%-40% higher than that of the straight hole nozzle, and the abrasive consumption is reduced by 20%.

Venturi nozzles are generally longer,   the venturi nozzle outlet gradually expands the design to make the abrasive initial velocity high and evenly spray on the workpiece surface. Venturi nozzles with a 1-1, 2-inch inlet are widely used in grit blasting processes for difficult-to-machine surfaces.

Common conventional model comparison table:
Flare inlet diameter is 32MM and 25MM

(1) There are two kinds of materials: tungsten steel and boron carbide:

[Tungsten steel] belongs to cemented carbide, also known as tungsten-titanium alloy. The hardness can reach 89~95HRA. Because of this, tungsten steel products (common tungsten steel watches) are not easy to be worn, hard and not afraid of annealing, but brittle.

The main components of cemented carbide are tungsten carbide and cobalt, which account for 99% of all components, and 1% are other metals, so it is also called tungsten steel. Commonly used for high-precision machining, high-precision materials, lathes, impact drills drills, glass cutter bits, tile cutters, hard Not afraid of annealing, but brittle. Belongs to the rare metal.

[Boron carbide] can absorb a large amount of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants, and neutron absorbers mainly control the rate of nuclear fission. Boron carbide is mainly made into controllable rods in nuclear reactors, but sometimes it is made into powder to increase the surface area.

Because of its low density, high strength, high temperature stability and good chemical stability. It is used in wear-resistant materials, ceramic reinforced phases, especially in lightweight armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easy to manufacture and low cost, so it is more widely used

(3) Applicable abrasives:

Sandblasted glass beads, glass sand, white corundum, brown corundum, garnet sand, black corundum, silicon carbide, steel sand, steel shot, iron ore, copper ore, copper furnace sand, quartz sand, floor sand, etc. Copper ore sand, also known as copper slag, has glass crystals with edges and corners without impurities, with hard particles, high rust removal efficiency by spraying, and the roughness of the sprayed parts can meet the requirements of smooth standards,Dust is harmless to human body, low price and other main features. At present, it is an ideal spray material for derusting the surface of modern steel at home and abroad. Widely used in shipbuilding, machinery, metal casting, railway, bridge construction and other industries such as metal structures. The annual output can reach 100,000 tons, and various specifications of segment sand, particle size sand, etc. can be processed according to user needs.

Meijun Sandblasting Equipment's Venturi Single Air Blasting Gun(Single Air Blasting Gun,) is better than that of straight hole nozzle, the eddy current phenomenon is obviously improved or no longer exists, and the pressure loss is greatly reduced.
