Which Is Better, Brown Corundum Sandblasting Or Garnet Sandblasting
Before, the sandblasting used brown corundum, but later it was replaced by garnet sand, why? Before making any more comparisons, we need to understand what the purpose of sandblasting is.
Sandblasting purpose
Sandblasting is the abrasive grinding and impact of different degrees on the surface of the processed object, so that the surface of the processed object to obtain cleanliness and different roughness, so that the mechanical properties of the processed object are improved and promoted, reduce the fatigue of the processed object, and extend its service life.
Therefore, there are certain requirements for the choice of sandblasting abrasives, and not all abrasives are suitable for sandblasting abrasives. Sandblasting abrasives need to meet the following properties and characteristics:
1, short grinding time, high efficiency, low price;
2, moderate hardness, good toughness, good self-sharpness, low sand consumption and can be recycled;
3, chemical properties to be stable, to be able to wear, acid and alkali corrosion;
4, the corners should be sharp, to have grinding force;
5, the sandblasting environment is better.
Comparison of brown corundum sandblasting and garnet sandblasting:
1, hardness: Relatively speaking, the hardness of brown corundum is much higher than the hardness of garnet sand, if the use of brown corundum sandblasting, it is easy to appear sandblasting phenomenon, easy to reduce work efficiency.
2, cost: One of the requirements of sandblasting abrasive is low price, brown corundum belongs to artificial corundum, the production steps are many, very labor-intensive, so the price will be relatively high, and garnet sand is a natural mineral resources, the price is relatively low.
3, environment: with general brown corundum sandblasting easy to produce ash not only pollute the environment, but also affect the health of workers, if the use of good brown corundum, less ash but the price is high, but with garnet will not use this problem.
Now you know why! However, although brown corundum has been replaced by garnet sand in sandblasting, many other uses can not be so easily replaced! After all, there are many advantages of brown sand.
