Tungsten Karbür Kumlama Memesi

General production nozzles materials include: steel, cast iron, tungsten carbide and ceramic materials. Most factories using steel nozzles, a few use ceramic nozzles, but the two nozzles generally shorter service life, far from ideal. Steel nozzles at high speed flow of sand effect, the hole gradually wear larger or a bell can not continue to be used. Tungsten Karbür Kumlama Memesi , also known as tungsten steel sandblasting nozzle. Tungsten Karbür Kumlama Memesi with high hardness, high strength, corrosion resistance, high temperature resistance and low coefficient of expansion and a series of excellent features, while its wear resistance and long service life, as compared with steel nozzles, can be increased by 20 to 25 times.

Sandblasting is a compressed air-powered pump or grinding, abrasive high-speed jet through the gun to reach parts of the surface cleaning and light decoration purposes. Currently, a wide range of blasting process used in machinery, petroleum, chemical, automotive, shipbuilding, aerospace, metallurgy, glass, coal and other industries. Nozzles are blasting equipment major wear elements, can be used with a variety of dry or wet blasting machine supporting the use of surface hardening, surface cleaning, the key surface coating, surface modification and jet cutting and other mechanical devices of the components. Tungsten Karbür Kumlama Memesi with high strength and toughness, good thermal conductivity, and its hardness is higher than metal carbide material, Tungsten Karbür Kumlama Memesi erosion rate is smaller than the metal material, the anti-erosion performance is better than metal nozzles, is an ideal choice for sandblasting nozzle material.

Tungsten Karbür Kumlama Memesi loses effectiveness
Erosion is the main failure to Tungsten Karbür Kumlama Memesinozzle, and it refers to the solid surface with the fluid containing solid particles to make contact with the relative movement, the surface loss of material occurs, the fluid carrying the solid particles may be high-speed airflow, can also be flow, the former produces blast type erosion, the latter known as mud-type erosion. Tungsten Karbür Kumlama Memesi wear a low erosion angle (≤15°) of erosive wear. Erosion behavior affect many factors, such as environmental parameters (such as the angle of attack, erosion rate, erosion of time and temperature, etc.), abrasive properties (such as hardness, particle size and shape, etc.), target properties (such as hardness, fracture toughness structure and microstructure.

Tungsten Karbür Kumlama Memesi classification structure
1. Straight hole Tungsten Karbür Kumlama Memesi. Its internal structure is only contraction and straight paragraphs, simple structure, easy to manufacture. This form of the inlet end of the nozzle can not overcome the phenomenon of the existence of the vortex, the pressure loss of the abrasive exit velocity less than 100m/s under 0.7MPa pressure conditions. Generally used for small sandblasting equipment.
2. Venturi Tungsten Karbür Kumlama Memesi. The structure is divided into the venturi nozzle contraction section, straight sections and diffusion segment of three parts, production difficulties. Work efficiency increased by 15% -40% higher than the straight hole nozzle, abrasive consumption reduced by 20%.
3. Dual Venturi Tungsten Karbür Kumlama Memesi. Constituted by around two nozzles, double Venturi nozzle blasting area than the standard venturi nozzle blasting area is large 35 percent, the exit velocity of about reduced blast media. This nozzle is typically used for surface treatment of large areas of moderate intensity.
4. The angle Tungsten Karbür Kumlama Memesi. With the direction of movement of the abrasive flow changes, it can be used to clean up the bridges, towers and other steel trusses, the inner surface of the pipe, so that these can clean up the difficult site by a direct blow to the abrasive, achieve the purpose of cleaning up.

Tungsten Karbür Kumlama Memesi applications
Tungsten Karbür Kumlama Memesi are mainly used in oil drilling, aircraft, ships, automobiles, bridges, construction, railways and other fields painting works and surface treatment. Sandblasting can be divided into two types which are dry sand and wet sand. Tungsten Karbür Kumlama Memesi belongings to rust, decontamination products, mainly for ships, bridges, chemical, container, water, machinery, pipes and other large equipment and spare parts surface blasting, rust removal, decontamination treatment. Tungsten Karbür Kumlama Memesi with high strength, high hardness, high wear resistance characteristics, carbide blasting fooling degrees (HRA) is 89-93, γdensity is 14.4-15g / cm3, the flexural strength is not less than 1500Mpa. Tungsten carbide is the most widely used material of the nozzle. It's significantly better wear resistance than alumina ceramic, the service life can reach hundreds of hours have been widely used in various structural nozzles.
