Some customers want to buy brown corundum or white corundum, and ask what specifications they want, F sand or W sand, which will make them confused. Today, Okayama Giken (Minerals) Co., Ltd. will talk about this question about the specifications of brown corundum.
Because the specifications of abrasive products include F sand, P sand, and W sand, as well as segment sand, grade sand (grain size sand), etc. Products of different specifications have very different uses and qualities. So what are the specific differences between so many types of brown corundum products?
First, let's talk about brown corundum F sand. This type of product is an ordinary brown corundum abrasive product. The main particle size ranges from 4 mesh to 240 mesh. The main use is grinding and polishing of various castings, and it can be applied to the production of various grinding wheels.
Compared with F sand, brown corundum P sand has better quality. It needs to go through multiple processing steps such as pickling, water washing, and air separation. Its particle size is generally from 8 mesh to 220 mesh. It is more used in the grinding process of high-precision workpieces.
The W sand in brown corundum belongs to the brown corundum micro powder series. The number ranges from W1-W63. The particle size is very fine and is basically used for polishing and grinding of ceramic products, precision workpieces, and glass products.
