What is the influence of abrasive particle size on the effect of stainless steel Sandblasting? | |
Abrasive particle size is one of the key factors affecting the effect of stainless steel Sandblasting, and has a significant impact on the roughness, glossiness, cleanliness and mechanical properties of the stainless steel surface. In terms of surface roughness, abrasives with larger particles have greater impact energy on the stainless steel surface during the Sandblasting process. When abrasive particles hit the stainless steel surface, deeper and wider pits are produced, which increases the surface roughness. For example, when using abrasive particles with a diameter of 1-2 mm for Sandblasting, the resulting stainless steel surface will show a noticeable rough texture, which is suitable for situations where high friction or high adhesion requirements for subsequent coatings are required. In contrast, abrasives with smaller particles produce shallower and finer impact pits, with relatively lower surface roughness, and a smoother surface effect can be obtained. For example, in some decorative stainless steel products with high requirements for appearance flatness, 0.1-0.5 mm abrasives are selected. For glossiness, large abrasive particles tend to destroy the original gloss of the stainless steel surface, making the surface appear matte or even frosted. This is because the impact of large particles will make the surface microstructure messy and the light reflection become diffuse. Small-particle abrasives can retain some gloss to a certain extent, or produce a soft gloss change on the surface under the right process. In terms of cleanliness, larger-particle abrasives can more effectively remove stubborn dirt, rust and oxide layers on the surface of stainless steel, because their greater impact force can better peel off these impurities. However, small-particle abrasives also have advantages in removing some fine impurities and slight oxidation phenomena, and can achieve a more refined cleaning effect. At the same time, the size of abrasive particles will also affect the mechanical properties of the stainless steel surface. For example, large particles may increase the probability of defects such as microcracks on the surface, while small particles are relatively mild, but the effect of cleaning and changing surface properties may not be as significant as large particles. In short, in practical applications, it is necessary to select the appropriate abrasive particle size according to the specific requirements of stainless steel products. | |
