Aluminium Oxide Material For Blasting South Korea

Because of the use of fixed mold forming in this experiment, with the increase of the amount of binder, the molding density will gradually increase(aluminum oxide for sand blaster). With the increase of the firing temperature, the viscosity of the binder will decrease and the fluidity will increase, the viscosity of the bond melt decreases(aluminum oxide 220 grit abrasive), which is conducive to the wetting of liquid phase to solid phase and the uniform distribution of the binding phase between the drunk particles.

Therefore, the cross-section of the sample is relatively rough(white fused alumina), and the fracture of the abrasive tool mostly passes through the combination phase and along the interface between the abrasive particles and the combination phase. However, if the sintering temperature is too high and the viscosity of the bond is too low(brown aluminium oxide 24 mesh), it will cause the foaming and deformation of the test strip of the grinding tool and reduce the bending strength of the test strip of the ceramic grinding tool.

The vitrification degree of the binding phase is higher, and the strength of the binding phase itself will be improved(garnet suppliers), which is also conducive to the improvement of mechanical strength. Because the ceramic corundum and other microcrystalline abrasives, which are fired at high temperature(aluminum oxide 40 grit), will be affected by high temperature to produce abnormal grain growth and destroy its microstructure, which will degrade its performance.

In this experiment, the increase of firing temperature did not cause the foaming and deformation of the test strip of the ceramic corundum abrasive tool(white aluminum oxide), which led to the decrease of the bending strength of the test strip. Therefore, in the experiment, the fluidity at high temperature increases(white aluminum oxide grit), increasing the firing temperature of the abrasives is an effective way to improve the mechanical strength of ca3h of the ceramic corundum abrasives.

In order to further analyze the change of the firing temperature on the macro mechanical properties of the ceramic corundum abrasives composite(glass bead blasting media suppliers), the micro mechanical properties of the ca3h ceramic corundum abrasives composite samples fired at different temperatures are tested The structure is analyzed. With the increase of firing temperature(white fused alumina for refractory), the bending strength of ca3h of the ceramic corundum abrasives is significantly improved.

The practice shows that before the realization of comprehensive automation(white corundum), with the increase of firing temperature, the bond distributes more evenly among the abrasive grains, the wetting and coating effect of the bond on the ceramic corundum abrasive grains increases(low sodium white fused alumina), the bond bridge connecting the abrasive grains becomes coarser and shorter, which is conducive to the improvement of the bond The improvement of the strength of ceramic corundum abrasives.

With the increase of firing temperature, the phenomenon of clarification similar to that in glass is produced(garnet abrasive). The porosity in the binding phase is reduced, the phase transformation is more compact, the degree of vitrification is increased, and the bond degree between the bond phase and the abrasive grains improves, and the strength of the binding bridge itself is increased(brown aluminum oxide sandblasting), which is also conducive to the improvement of the strength of the grinding tool test strip.

The most effective method is that the strength of the ceramic corundum abrasives depends not only on the properties and content of the ceramic bond(steel grid), but also on the microstructure of the ceramic corundum abrasives to a great extent. Moreover, within the range of firing temperature set in this test(brown aluminum oxide 16 grit), the grinding tool test strip is not produced due to the increase of firing temperature Foaming and deformation phenomenon lead to the decrease of the strength of the test strip.
