80 Grit Aluminum Oxide Blasting Media Brazil

The impact strength of the bond reflects the ultimate strength of the white fused alumina tool when it resists the impact load. Impact strength is the index to measure the toughness and brittleness of the bond. In the process of forming grinding (such as thread grinding and gear grinding), the fused aluminium oxide grinding wheel should have good shape retention and good bond toughness.

Because of the high hardness of the white aluminum oxide workpiece material, in order to prevent the workpiece from being burned and maintain a high grinding rate, it is required to have a good self sharpening performance of the grinding tool and a good brittleness of the bond. The brittleness and toughness of the binder are comparatively speaking. At present, the pink fused alumina research on the brittleness and toughness of bond is not enough at home and abroad.(80 grit aluminum oxide blasting media brazil)

In general, only by adjusting the chemical composition of the white corundum, to change its brittleness and toughness. The brittleness of quartz glass is very large. When R2O and RO are added into SiO2, so quartz powder is introduced into the binder, the toughness decreases; Fe2O3 and A12O3 are introduced, the toughness increases. For black aluminum oxide 70 grit abrasive media tools, the hardness is high and the toughness is large when there is no crack inside.

(80 grit aluminum oxide blasting media brazil)The impact strength of the pink alumina bond is determined by the impact strength tester. According to a certain formula hardness point, make (120 ± 2) × (15 ± 0.2) × (10 ± 0.2) rectangular oilstone or (120 ± 2) × (20 ± 0.2) × (20 ± 0.2) square oilstone samples, each of which has more than 5 pieces. Choose a pendulum of 10kg 1cm for the ceramic bond. After the test strip is broken, the dial scale number is the work consumed by the black aluminum oxide blast media test strip.

The elastic modulus of black silicon carbide factory bond can be defined as: In a certain stress range, the strain is reversible, that is, when the atomic spacing returns to the initial state after the stress is removed, the strain disappears, which is called elastic deformation. At this time, there is a simple ratio constant between the stress and strain, for the tensile stress: g = EE. The corundum sand proportional constant e is called the modulus of elasticity or young's modulus. 

(80 grit aluminum oxide blasting media brazil)when the ceramic abrasive sample is under tension or compression, it will produce corresponding elastic deformation, and the black fused alumina ratio constant of stress and strain is called elastic modulus. The purpose of this property is to show the viscosity change of the sintered binder after melting at high temperature. The fluidity of the binder refers to the reciprocal of the viscosity of the aluminium oxide 36 grit high temperature melt of the binder.

Ceramic abrasives are multi-phase (or component) materials composed of binders, chrome corundum particles, pores, etc. their elastic modulus is determined by the elastic modulus of binders and abrasives (pores reduce the elastic modulus). Elastic modulus of the composite: after the binder is melted to the firing temperature, the brittleness of glass increases, the viscosity decreases and the aluminum oxide sandblasting media flow disperses.(80 grit aluminum oxide blasting media brazil)
