What is the function of emery and where can it be used?

Properties and uses of emery: There are two basic varieties of emery, black silicon carbide and green silicon carbide, both of which belong to α-SiC. ① Black silicon carbide contains about 98.5% SiC, and its toughness is higher than that of green silicon carbide. It is mostly used to process low-resistance materials, such as glass, ceramics, stone, refractories, cast iron, nonferrous metals and so on. Green silicon carbide contains more than SiC99% and has good self-sharpening. It is mostly used for machining cemented carbide, titanium alloy, optical glass, honing cylinder liners and fine grinding high-speed steel tools. In addition, there is cubic silicon carbide, which is a yellow-green crystal prepared by a special process. The abrasive tool used for manufacturing is suitable for ultra-precision machining of bearings, and the surface roughness can be machined to Ra32 ~ 0. 16 micron to Ra0.04~0.02 micron at one time.

(1) can be used as abrasive, such as grinding wheel, whetstone, grinding head, sand tile, etc.

(2) emery abrasive is the first choice for sand blasting technology, and it is also used for sand blasting and rust removal to clean the workpiece and its materials.

(3) It can also be used for polishing and grinding hardware, glass, precious stones and jade articles. Silicon carbide has four main application fields, namely: functional ceramics, advanced refractories, abrasives and metallurgical raw materials. At present, silicon carbide coarse materials can be supplied in large quantities,

It is not a high-tech product, and the application of nano-silicon carbide powder with high technology content cannot form economies of scale in a short time.

(4) Special emery for wear-resistant floor: Se-Ti alloy aggregate wear-resistant floor agent, mineral alloy aggregate floor hardener, mineral alloy aggregate floor hardener, metal aggregate wear-resistant floor hardener, nonmetal aggregate floor hardener, colored wear-resistant floor, wear-resistant embossed floor and wear-resistant hardened floor.
