Tungsten Carbide Coating for High Speed Mixer Blades

Tungsten carbide is a compound of tungsten and carbon. It is a black hexagonal crystal with metallic luster and similar hardness to diamond. It is a good conductor for electricity and heat. Tungsten carbide is insoluble in water, hydrochloric acid and sulfuric acid, and soluble in mixed acid of nitric acid and hydrofluoric acid. Pure tungsten carbide is fragile. If a small amount of titanium, cobalt and other metals are added, the brittleness can be reduced. Tungsten carbide used as cutting tools for steel is often added with titanium carbide, tantalum carbide or their mixture to improve explosion resistance. The chemical properties of tungsten carbide are stable. Tungsten carbide powder is used in cemented carbide production materials.


Tungsten carbide powder (WC) is the main raw material for producing cemented carbide, chemical WC. Wolfram Carbide, also translated as tungsten carbide, is a black hexagonal crystal with metallic luster, hardness similar to diamond and good conductor for electricity and heat. The melting point is 2870 C, the boiling point is 6000 C, and the relative density is 15.63 (18 C).


After years of practice in the battery industry, our company has accumulated perfect solutions for the introduction of iron ion isolation and wear resistance reduction impurities into cathode materials and battery production equipment, and greatly improved the self-discharge performance of cathode materials after being processed into finished batteries.


In the production process of battery materials, there is no contact with iron. Stainless steel is used for two stirring spirals in conical cylinder and cylindrical mixer of many companies. But during the stirring process of battery powder, the cylinder will be constantly rubbed. After a long time of work, the cylinder and spiral will be greatly worn and worn down. When stainless steel is mixed with battery powder, the iron content in stainless steel reaches 70%, which seriously pollutes battery powder.


The contact part of high-speed mixer (slurry blade, tank body) in cathode material production equipment is treated with tungsten carbide as a whole, which will never fall off. The high-speed mixer (blade, tank) was treated as a whole to solve the problem of introducing elements such as sodium borosilicate and other impurities into cathode materials introduced by FRP coatings in the past. The impurities brought by wear of stainless steel are reduced and the self-discharge ratio of batteries is greatly reduced after the treatment of stirring paddle of batteries slurry-adjusting equipment.
