Abrasive wheels Using new materials to replace fired ceramic abrasive quartz sand for sand pad

Using new materials to replace fired ceramic abrasive quartz sand for sand cushion, improve the labor environment is an urgent need to resolve the issue. In this paper, resulting in a ceramic abrasive plant root cause silicosis - quartz sand mats were analyzed, through access to a lot of relevant information on the physical and chemical properties of certain materials were tested, and test fired ceramic abrasive mounted.  abrasive grinding  efforts, finally found a promising replace quartz sand mat new material. The main research work and test results of an overview of the relevant aspects of the quartz crystal structure of theoretical knowledge. It can be seen, the quartz crystal having a complex multi-resistance. Quartz sand in ceramic  polycrystalline diamond  and cooling process, due to changes in polycrystalline quartz occur when inevitably accompanied by changes in the volume, the resulting stresses and cracks, making their strength reduced from large particles into small particles even powder.
