Tungsten carbide spray nozzle has good wear resistance, long life, is the key determinant of coating efficiency and coating quality. When the paint, the paint atomization, flow, spray rate by the geometry of the nozzle, with the pore size determined by the accuracy of machining. Select the nozzle and its technical parameters has become the key painting is one of the coating efficiency and coating quality assurance of the most effective means.
 
The most widely used standard nozzle, the nozzle opening was olive, oval spray pattern, many models of this nozzle, the spray pattern width of 150mm to 600mm, the paint discharge amount (0.2 ~ 5.0) L / min, even up to 10L / min or more, to meet the needs of a variety of spray, which is called the equivalent diameter of the nozzle diameter, the so-called equivalent diameter refers to the opening of the nozzle diameter was olive, equivalent to the same amount of spray paint circular opening of the nozzle diameter.
 
Tungsten carbide nozzles are usually used to sandblasting, therefore, users also call them tungsten carbide sandblasting nozzles. The hardness reached over HRA90 degree while the anti-bending degree reached over 2300N/mm. On machining tungsten carbide spray nozzle, we do the precision grinding and surface treatment to achieve Ra0.1 of the bore roughness and the Ra0.025 of the R place of both ends. There is a scientific curvature radius design in the both entrance. This design can ensure a smooth transit of the thread. Due to the overall materials processing, and no elevation in the bore, the phenomenon of easy-bending and plugging has been improved comparing with the ruby nozzle.

Grade List

Tungsten carbide spraying nozzles  spcification

Use superfine nanometer tungsten carbide particles, the wear-resisting performance to the next level, superior

wear resistance makes it far beyond the ordinary tungsten carbide,The service life of the nozzle.Cobalt content of less than 0.6%, density of 15.45 g/cm3 ~ 15.6 g/cm3, bending 2000 mpa to 2400MPa.Super oxygen resistance, small thermal expansion coefficient, unique high hardness and density, far beyond the other similar products, the use of hard Alloy tube abrasion resistance stronger.

Sand tube due to high-speed abrasive particle erosion, its selection is very important.Sand tube material, in general, must have high hardness, high resistance Grinding, both be short of one cannot.Generally for tungsten carbide composite materials processing.Usually, cemented carbide, WC as the main resistance,Grinding phase exists in the form of particles, CO, just as the binder.
