The difference between garnet sand, quartz sand and emery sandblasting abrasive
Garnet sand is a common sandblasting abrasive. Compared to garnet sand, the well-known abrasives include quartz sand, emery, brown corundum, steel shot steel grit, etc. Next, we will make a simple introduction to several common abrasives. Analysis.
The difference between garnet sand, quartz sand and emery sandblasting abrasive
Garnet sand is a kind of natural abrasive formed by natural processing. It has high hardness and good sandblasting effect. It can reach the highest sandblasting effect of sa3 level. It is not rich in free silicon, contains very little dust, and does not appear dust. The phenomenon of flying.
Quartz sand should be used more frequently before. It is also an abrasive for natural mineral processing, but the effect of sandblasting is relatively poor and there are residual soft impurities, which then appear and bubble after painting. In the process, free silicon harmful substances will float, which will endanger human health and pollute the environment.
There are two types of emery: man-made and natural. Artificial emery is silicon carbide. The color is mainly black and green. It is mainly used as a raw material for mold production and can also be used for polishing, grinding and sandblasting, but the price is relatively high.
