Brown corundum can be used as an abrasive, and the effect is relatively ideal, but the user has encountered problems in the storage of brown corundum abrasive. Because the amount of brown corundum abrasive purchased each time is relatively large, it can only be placed in the open air, but will this affect the quality and performance of the product?
Xiaobian is mainly aimed at summer, but in the case of dry summer weather, the brown corundum abrasive directly placed in the open air also has a certain impact. Because there is a capillary gap in the production of brown corundum itself, with a certain hydrophilicity, so in the summer with changeable weather, brown corundum is also very easy to get wet.
