What does shot blasting mean? Shot polishing can be understood as shot blasting treatment, which is also one of the metal rust removal methods. We usually divide rust removal into two kinds: manual rust removal and mechanical rust removal. Manual rust removal refers to the use of sandpaper, wire brush and other ways for manual grinding, and shot blasting rust removal is also shot blasting grinding, is a mechanical rust removal method. The following to tell you about the principle of shot polishing, I hope to help you.
The motor drives the impeller, and uses the effect of centrifugal force to throw out the steel pellets (generally refers to 0.3mm~2.0mm cast steel pellets or abrasives of stainless steel pellets) to hit the surface of the metal, so as to achieve the effect of rust removal and peel removal, the rust removal level reaches Sa2.5 or Sa3.0, and the manual rust removal is not up to this level. Shot polishing not only has the effect of rust removal, it can increase the roughness of the metal surface, which is conducive to the adhesion of the paint of the subsequent spraying process. Another function of shot polishing is to strengthen, eliminate the internal stress of the metal, and increase the service life.
The role and application field of shot blasting is very wide, and almost most mechanical fields will use the shot blasting process. For example, shipbuilding industry, auto parts, aircraft parts, tank surface treatment, Bridges, steel components, pipeline anticorrosion treatment process. In addition, there are some emerging industries, such as stone lychee surface treatment, steel bridge floor waterproof wool treatment, concrete floor wool to float slurry, airport to black tire marks and so on. Because it has the advantages of high efficiency, good cleaning effect and convenient application, it has been widely loved by users.
