Tungsten carbide coating mainly refers to the wear areas of electrode materials, cathode materials, and lithium battery material production equipment, including special-shaped parts, stirring walls, blades, screws, and crushing equipment.
Tungsten carbide spraying mainly refers to the wear parts of electrode materials, cathode materials, and lithium battery material production equipment, including shaped parts, stirring walls, blades, screws, and crushing equipment. To isolate metal foreign objects, tungsten carbide spraying manufacturers apply coating protection on the surfaces of production equipment and material contact parts.
Tungsten carbide spraying is a highly satisfactory wear-resistant, high-temperature resistant, non-metallic material, so most of the vulnerable parts in the lithium battery material production process are protected using tungsten carbide spraying.
After self-discharge and high-temperature spontaneous combustion of lithium cathode materials, magnetic materials exceed the standard. Due to the high isolation requirements for metal foreign objects in lithium battery materials, some manufacturers even require the PPB value of magnetic foreign objects to be less than 10, while many lithium battery material manufacturers can only meet the 50 PPB standard. Product quality determines market sales.
Imported tungsten carbide spraying from abroad can be used for lithium battery material production equipment for 1-3 years or more. The demands of equipment managers are particularly noteworthy because the wear degree of tungsten carbide spraying is uneven in terms of equipment wear. For example, blades and blade shafts, screw shafts, and some mixer tube walls or the bottom of tube walls experience more wear. The total equipment area is 5 square meters. Tungsten carbide spraying is "worn off" in 0.1 square meters of wear areas, but the coating on the other 4.9 square meters seems "unscathed." This indeed affects the quality of battery materials this time.
