Aluminium Oxide Blasting Grit Manufacturers UK

This differential equation shows that the relative change in the inductance of the 220 grit aluminum oxide blast media inductor coil is proportional to the change in the dielectric permeability of the coil. In the measurement, the change of the magnetic permeability of the medium is caused by the magnetic content of the aluminum oxide blast media 60 grit. Therefore, as long as the relative change of the coil inductance is measured, the magnetic content of the abrasive can be converted.

In addition to measuring the magnetic content, the 80 grit aluminum oxide blasting media must be repeatedly sucked with a horseshoe-shaped permanent magnet of a specified specification to check whether there are iron alloy particles. When using JS11-G1 type magnetic substance analyzer to measure, the content of magnetic substance in the abrasive is standard. When using JSⅡ type magnetic substance measuring instrument to measure, the content of magnetic substance in the low density white alumina is standard.


F30 and ferrous alloy 100 grit aluminum oxide media particles with coarse sizes that do not pass 45 * sieve are zero; F36 ~ F90 have zero ferrous alloy particles with the lowest sieve size when they do not pass the particle size inspection. Single particle compressive strength is the arithmetic average value of the maximum vertical pressure (ie, crushing pressure) that the basic particles of a certain size brown fused alumina manufacturer can withstand, as its compressive strength value.


The content of ferroalloy particles in various white fused alumina: The pH value of the abrasive is the hydrogen ion concentration in the leaching solution obtained by immersing the abrasive in neutral water, that is, the pH. The purpose of measuring the pH value of the abrasive is to select a suitable binding agent when manufacturing the abrasive to ensure the quality of the product. white fused alumina suppliers can be a = (7 ~ 8) × 10 * · K-1. 


For example, neutral 1200 grit aluminum oxide should be selected when manufacturing resin abrasives, because alkaline substances will accelerate the cracking of phenolic resin, shorten the storage period of the abrasives, and reduce the strength of the abrasives. The abrasive ability of the abrasive is marked under a certain abrasive condition with a certain size and weight of white fused alumina manufacturer and the weight of the object to be abraded. The grinding capacity of different abrasives is different.


The grinding capacity of silicon carbide is about twice that of white aluminum oxide. The grinding capacity of green silicon carbide is slightly higher than that of black silicon carbide. The thermal properties of honing abrasives are mainly thermal expansion, thermal conductivity, melting point, specific heat and thermal stability. The linear expansion coefficient a refers to a change in relative length that occurs in a fixed direction each time the object white fused alumina price temperature rises by 1 ° C. 


Often only the coefficient of linear expansion of the abrasive is measured. The linear expansion coefficient of the 46 grit aluminum oxide is measured by adding a certain proportion of binder to the granular abrasive and pressing it into a test bar of a predetermined shape. The linear expansion of the sample is measured by a thermal expansion meter, and then the linear expansion coefficient of the brown fused aluminium oxide is converted according to the sand knot ratio .


The linear expansion coefficient of white corundum can be a = 4.4 × 10-5 · K in the range of 250 ℃ to 1400 ℃. The purpose of measuring the linear expansion coefficient of abrasives is to select a binder that is similar to the linear expansion coefficient of abrasives and has a similar expansion trend when manufacturing ceramic abrasives, to prevent the brown fused aluminum oxide suppliers from cracking during heating and cooling, and to ensure that The mill has sufficient strength.
