Sandblasting Gun And Sandblasting Nozzle

Our Sandblasting Gun And Sandblasting Nozzle is very excellent quality. Sand blasting is powered by clean compressed air separated by deoiled water, so that the dried sand (or abrasive) forms a high-speed sand stream (or abrasive stream) that strikes the surface of the metal part, making it strongly impact the surface of the part, relying on sand (or The cutting action of the abrasive) processes the metal parts to achieve the process of cleaning and modification.
Sand blasting is mainly used for some materials and parts that are not easy to adopt conventional treatment methods, such as high-strength steel which is very sensitive to hydrogen embrittlement, magnesium alloy parts which are easily corroded in aqueous solution, cast iron parts, machine tool bases and water gates. .
The purpose of sand blasting is to clean the surface of the parts, such as scale, rust, carbon deposits, welding slag, paint marks or wear marks, reduce the surface roughness of the parts, and increase the bonding force between the cover layer and the substrate. This technology is applied in the coating process. Extremely common.
1 Classification of sandblasting
Sand blasting can be divided into dry blasting and wet blasting. At present, dry blasting is still the main application. The sand grains are quartz sand, silicon carbide and river sand, of which quartz sand is most commonly used.
The quality of sand blasting depends on factors such as part material, air cleanliness, pressure, nozzle diameter and abrasive grain size.
Wet blasting is mainly to reduce sand and prevent pollution. Wet blasting is mainly water blasting, m (water): m (abrasive) is about 7: 3, and water should be added 1. 5% ~ 2. 0% rust inhibitor to prevent rusting of parts.
The working principle is still to use clean compressed air separated by oily water, press the prepared into the nozzle, and then spray it through the nozzle to the surface of the part. It should be constantly stirred during work to prevent precipitation of the abrasive.
In order to improve the spraying method, when the spraying method combined with the nozzle and the sand blasting gun is adopted, the effect is ideal, and the effect of prolonging the service life of the nozzle can also be achieved.
