White Aluminum Oxide Rubbing Compound Mexico

The work of establishing and popularizing detection technology and automation system is of great significance, which has been reflected in many guiding documents(white corundum). When ca3h was fired at 870 ℃, the high temperature fluidity of the bond increased further, the bond distributed more evenly among the abrasive particles, and the wetting and wrapping effect of the bond relative to the abrasive particles increased(white aluminium oxide super fine). The bond strength between the bond phase and the abrasive particles increased.

The most significant change is that the number of pores in the bonding phase is greatly reduced(brown fused alumina price), the bonding phase is more compact, and the degree of vitrification of the bonding phase is also significantly improved, which is conducive to the improvement of the strength of the bonding bridge itself(garnet abrasive price). Each ceramic corundum abrasive is a dense alumina structure composed of thousands of submicron or micron sized fine crystals, and the bond distribution is very uniform.

The fracture surface of the sample is relatively smooth(black aluminum oxide), and the crack propagation is not only through the bonding phase and along the interface between the abrasive particles and the bonding phase, but also through the ceramic corundum abrasive particles(aluminum oxide 30 or 40 grit). There are only a few pores in the binding phase, the binding phase is the densest and the vitrification degree is the highest. On the basis of a large number of experiments and tests, the following conclusions were obtained.

The decrease of the ratio of Al to Si in the ceramic bond will lead to the decrease of the fire resistance of the bond(white fused alumina). When ca3h is fired at 900 ℃, the high temperature fluidity of the bond is fully improved. Moreover, the binding agent has a significant effect on the wetting and wrapping of the abrasive particles(glass bead abrasive). The binding area of the binding agent is larger than that of the abrasive particles, and the binding bridge between the abrasive particles becomes coarser and shorter.

When the sintering temperature is too high, the grain is easy to grow abnormally(pink aluminum oxide), which destroys the microstructure of the ceramic corundum abrasive particles and leads to the deterioration of the abrasive properties(brown aluminum oxide factory). A new type of ceramic corundum abrasive developed by the Key Laboratory of advanced ceramics and processing technology of Tianjin University and a self-made 3H bond were used to make a test strip of ceramic corundum abrasive.

In this paper, the manufacture of ceramic corundum abrasives is studied. R2o-mo-b2o-al2o3-sio2 city aluminum silicate glass was selected as the basic ceramic bond system(white aluminum oxide). The influence of the composition of the ceramic bond and the preparation process on the bond and the performance of the ceramic corundum abrasives was studied(steel shot abrasive). The effect of the amount of the bond and the sintering temperature on the performance of the ceramic corundum abrasives was also studied.

When the aluminum silicon ratio is 3.0, the fire resistance of the bond is 826 ℃(glass beads manufacturers), when the aluminum silicon ratio is reduced to 1.4, the fire resistance is 762 ℃, the bending strength of the ceramic corundum abrasive increases first and then decreases with the increase of the aluminum silicon ratio, and when the aluminum silicon ratio is 2.6, the strength can reach 54.6mpa(aluminum oxide blasting media). The increase of the aluminum turnover ratio in the ceramic bond will lead to the increase of the fire resistance of the bond.
