Processing of ceramic dispensing valves
The production of ceramic dispensing valves requires the preparation of high-purity, well dispersed, ultrafine particles and narrow particle size distribution powders. There are many methods to prepare ultrafine zirconia powders. The purification of zirconia mainly includes chlorination and thermal decomposition, alkali metal oxidation decomposition, lime melting, plasma arc, precipitation, colloid, hydrolysis, spray pyrolysis, etc. Powder processing methods include coprecipitation, sol gel, evaporation, supercritical synthesis, microemulsion, hydrothermal synthesis and vapor deposition.
Performance of ceramic dispensing valves
1. The ceramic valve uses high-tech new ceramic structural materials to make the sealing and vulnerable parts of the valve. The ceramic material has chemical stability and extremely high hardness (Rockwell hardness HRC90), second only to diamond. Therefore, this valve has extremely high wear resistance, corrosion resistance, and erosion resistance, as well as good insulation and low thermal expansion, greatly extending the service life of the valve.
2. Ceramic dispensing valves can greatly improve the smoothness and sealing of industrial pipeline systems, minimize leakage, and thus protect the environment.
3. The use of ceramic dispensing valves can greatly reduce the frequency of valve maintenance and replacement, improve the safety and stability of supporting equipment operation systems, and save equipment repair costs.
4. The raw materials for manufacturing ceramics are extensive and the cost is low. Using ordinary elements such as aluminum, carbon, and silicon can produce high-performance ceramic materials, which can save a lot of metal materials and rare mineral resources.
