Stone processing abrasive composition and classification

Is abrasive abrasive, binders, fillers, porosity, and attachments and other components.
The basic requirements of the abrasive:
1, the hardness is higher than the hardness of the material to be processed;
2, has a certain toughness and strength, and with sharp skills.
3, should have a certain degree of mechanical strength.
4, maintaining the inherent high strength and hardness (hardness or thermal stability or red).
Abrasive Category:
Abrasive for natural and artificial sources can be divided into two categories, according to the nature of abrasives and super abrasives can be divided into two general categories.
Common natural abrasives:
A natural diamond: diamond abrasive with high efficiency, long life, low cost, good quality grinding series of advantages.
2, quartz sand: also known as silica sand, 95% of the particles of quartz sand.
3, garnet sand: to loose abrasives for cutting soft marble blocks.
4, natural corundum: mainly composed of A1203. Mohs hardness of 9, second only to diamond.
Commonly used artificial abrasives:
1, corundum: Suitable for grinding the tensile strength of the material, the price is cheaper.
2, corundum: grinding capacity slightly higher than corundum (0.12 for the diamond). Moderately fine grinding.
3, chromium corundum: purple or pink, slightly higher than corundum grinding capacity (as diamond 0.13), especially for the profile grinding. Widely used alloy gears, cutting tools, thread management tools and instruments of precision grinding parts.
4, SiC: commonly known as carborundum, its ability to wear diamond 0.25-0.28, brittle and sharp, is very versatile and an abrasive.
5, synthetic diamond: wear ability and natural diamond almost there in the stone industry will gradually replace traditional.
