On the classification of blasting abrasives
The abrasive products are mainly divided into two categories: corundum abrasives and silicon carbide abrasives. Specifically, there are basically the following:
Single crystal corundum abrasives, whose particles are composed of single crystals, have good polygonal cutting edges, high hardness and toughness, strong grinding ability, and low heat output during grinding. The disadvantages are higher production costs and lower yields. , So the price is relatively high. Zirconium corundum abrasives are also crystalline compounds, with slightly lower hardness, finer crystal size, and good abrasion resistance.
, Black silicon carbide abrasive, green silicon carbide abrasive, cubic silicon carbide abrasive, cerium silicon carbide abrasive, etc., belong to silicon carbide abrasive, the main component is silicon carbide, high hardness, brittleness, sharp abrasive particles, good thermal conductivity, wear resistance Stronger, more suitable for processing hard and brittle metal and non-metal products. —Sandblasted tube corundum abrasive, the main components are medium hardness, high toughness, sharp particles, low price, suitable for processing high tensile strength metal. Microcrystalline corundum abrasive and black corundum abrasive are both derived from white corundum abrasive. Its hardness is slightly higher than that of brown corundum, but its toughness is poor. It is easy to cut into the workpiece during grinding. Strong and efficient. Chrome corundum abrasive is a derivative of it.
