Because there are several types of brown aluminum oxide abrasive products, such as F sand, P sand, and W sand, as well as segment sand, No. sand (grain size sand), etc. The uses of products of different specifications are very different, and the quality is also different. So what are the specific differences between so many types of brown fused alumina products?
First of all, let's talk about brown aluminum oxide F sand. This type of product is an ordinary brown fused alumina abrasive product. The main particle size ranges from 4 mesh to 240 mesh. The main use is the grinding and polishing of various castings and workpieces, and can be applied to the production of various grinding wheels.
Compared with F sand, brown aluminum oxide P sand has better quality. It needs to go through multiple processing steps such as pickling, water washing, and air selection. 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 aluminum oxide belongs to the brown fused alumina micro powder series. The segment ranges from W1-W63, and the particle size is very fine. It is basically used in the polishing and grinding of ceramic products, precision workpieces, and glass products.
The brown aluminum oxide P sand, F sand, and W sand introduced above all belong to the range of brown fused alumina particle size sand, because they all have fixed particle size numbers, also called number sand. Brown fused alumina segment sand is different, for example, the commonly used 1-3mm, 3-5mm, 325-0, etc. are all segment sand, because the particle size of this type of brown aluminum oxide is between two values, and is mostly used in the production of refractory materials.
