Effect of grit size of sand blasting abrasive on sand blasting effect
When choosing the abrasive, many people only consider the price and choose the appropriate abrasive, while few people consider the size and shape of the abrasive. In fact, the particle size and shape of the abrasive
It has a direct impact on the blasting speed and also affects the cleanliness and roughness of the surface.
Generally, the surface particles of large grain garnet sandblasting will be relatively large when sandblasting, and the uneven surface roughness will lead to impurity residues, which will often be difficult to meet the coating standards. Service hardness
Large small particles and multi angle abrasives, so that the surface will be cleaner after sandblasting and can easily reach the SA3 surface sandblasting grade.
Through constant experiments, the small grain garnet sandblasting abrasive has a very good effect in sandblasting application because of its proper size and high specific gravity. The abrasive copper slag used before is large per kilogram
There are about 1 million abrasive particles. Our 30/60 # garnet contains about 1 million abrasive particles per kilogram. Therefore, by comparison, the garnet abrasive on the surface of sandblasting object per square meter is copper slag 11 times of abrasive. This is why the sand blasting speed of small grain garnet sand is faster and the cleaning effect is better than that of large grain copper slag. At the same time, our garnet sandblasting can be recycled 5-7 times.
