Single Inlet Air Sandblasting Gun (Class A Hot Pressed Sintered Pure Boron Carbide)

Details

Dongguan Meijun: Single Inlet Air Sandblasting Gun (Class A Hot Pressed Sintered Pure Boron Carbide)
Single-entry Boron Carbide Blasting Gun, Venturi Blasting Gun, Long Shot Blasting Gun, Pressure Blasting Gun

Single-inlet sandblasting gun Alias: Venturi nozzle: (Venturi nozzle, English Venturi Nozzle)

The structure of Venturi sand blasting nozzle is divided into three parts: contraction section, straight section and diffusion section. It is difficult to make. Venturi nozzles have better aerodynamic performance than straight-hole nozzles, and the vortex phenomenon is significantly improved or not.   Re-existence, the pressure loss is greatly reduced. Under the same pressure condition, the outlet speed of the abrasive can be more than doubled, the working efficiency is increased by 15% -40% compared with the straight hole nozzle, and the abrasive consumption is reduced by 20%.

Venturi nozzles are generally longer,   The gradually expanding venturi nozzle outlet design makes the initial velocity of the abrasive high and uniformly spray the workpiece surface. This Venturi nozzle with an inlet of 1-1 and 2 inches is widely used for sandblasting of difficult-to-machine surfaces.

General conventional model comparison table:
Flare entrance diameter is 32MM and 25MM

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

[Tungsten steel] is a hard alloy, also called tungsten-titanium alloy. The hardness can reach 89 ~ 95HRA. Because of this, tungsten steel products (commonly known as tungsten steel watches) are not easy to be worn, hard to be annealed, 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 on high-precision machining, high-precision materials, lathes , impact drill bits, glass cutter heads, tile cutters , hard and not afraid of annealing, but brittle. Belongs to rare metals.

[Boron carbide] can absorb a large number of neutrons without forming any radioactive isotopes, so it is an ideal neutron absorber in nuclear power plants, and the neutron absorber mainly controls the rate of nuclear fission. Boron carbide is mainly made into a controllable rod shape in a nuclear reactor, but sometimes it is made into a powder shape because of increasing surface area.

Because of its low density, high strength, high temperature stability and good chemical stability. Used in wear-resistant materials, ceramic reinforcements, especially in light armor, reactor neutron absorbers, etc. In addition, compared with diamond and cubic boron nitride, boron carbide is easier to manufacture and less expensive, so it is more widely used.

(Three) applicable abrasives:

Sandblasted glass beads, glass sand, white corundum, brown corundum, garnet, black corundum, silicon carbide, steel sand, steel shot, iron ore, copper ore, copper furnace sand, quartz sand, floor sand, etc. 粉尘对人体无害,价格低等主要特点。 Copper ore, also known as copper slag, has glass crystals with no impurities at the edges and corners. It has hard particles, high efficiency of spray rust removal, and the roughness of the sprayed parts can meet the requirements of smooth standards . And other main features. At present, it is an ideal spray material for derusting of modern steel surfaces at home and abroad. It is widely used in shipbuilding, machinery, metal casting, railway, bridge construction and other industries. The annual output can reach 100,000 tons, and can process various specifications of sand and grain size sand according to user needs.
