What indicators of garnet abrasives are customers most concerned about?
1: Density: In physics, density refers to the mass per unit volume. For example, the density of RZG garnet abrasive is 3.9-4.1g/cm3.
Very similar to density is specific gravity, also called relative density. The specific gravity of solids and liquids is the ratio of the density of the substance (completely dense state) to the density of pure H2O (999.972 kg/m3) at standard atmospheric pressure and 3.98°C. The specific gravity of almandine garnet abrasive is 4.1-4.4.
2.: Wear rate: it is generally expressed by “the amount of material wear under unit load per unit time”. The lower the wear rate of garnet abrasive, the longer it will last.
3.: Hardness: Hardness has different testing methods in different industries, and the conclusions are not the same. The hardness of garnet abrasive indicates its wear resistance. Apart from diamond, corundum, and topaz, garnet is the only one found in nature.
4: Porosity: Porosity refers to the percentage of the pore volume in bulk materials to the total volume of the material in its natural state. In the filter material industry, the porosity mainly affects the particle size of filtered impurities, such as haixu garnet abrasives. The porosity reaches 50%.
