Applications of Ceramic Valves in Carbide Slurry
Vinyl chloride used for production was mainly produced by acetylene in this context. In the specific production and processing process, the main structural material is calcium carbide, which includes a series of carbon raw materials such as coke. Calcium carbide also contains a certain amount of quicklime. These materials need to be processed before calcium carbide can be synthesized. The synthesis needs to be set up in a resistance arc furnace, which must be kept at a high temperature. When calcium carbide reacts with water, a slurry is generated. The main material of this slurry is calcium hydroxide, accompanied by a certain amount of coke, silica, tar impurities, calcium carbonate, and other raw materials. During production, the substances in the calcium carbide slurry significantly impact the valves of the slurry pipeline. The presence of coke, ferrosilicon, calcium carbonate, and other substances seriously impacts and wears the pipeline.
For this reason, technicians choose a metal paddle valve as the main slag valve. This valve is installed at the bottom of the generator, and the valve plate is made from metal. On-site analysis by technicians found that the wear of the plate is mainly caused by the impact of impurities in the carbide slurry. Due to the weak impact resistance of the plate's surface, the gate becomes rough within a short production period. Even after long-term use, problems such as internal leakages of the valve still occur.
To avoid these problems, maintenance personnel must increase the frequency of maintenance, which not only increases maintenance tasks but also wastes production resources. In chlor-alkali industrial production, some areas contain solid particles and generally have a certain degree of corrosiveness. Using only plastic-lined valve cores in this area will inevitably cause some damage. If the valve plate wears after long-term operation, its surface will become rough, causing more internal leakages and inducing jamming.
Applications of Ceramic Valves in Solid Particles
Structural ceramics contain silicon oxide, which has characteristics of super hardness, relatively low density, outstanding lubrication performance, corrosion resistance, and wear resistance. Technical analysis found that silicon oxide's characteristics make it suitable for chlor-alkali industrial production and the manufacture of ceramic valves. To verify the use of silicon oxide in valve production, technicians researched its application in other fields and found it is mainly used in mechanical components such as seal rings, bearings, permanent molds, and steam turbine blades. To enhance the application of structural ceramics, technicians developed various valve production methods and conducted testing. After experimental studies, technicians concluded that valves made from all-ceramic or steel-lined ceramic can meet various needs in chlor-alkali production. Additionally, ceramic materials have a natural lubrication function, improving sealing performance and wear resistance, solving leakage issues, and providing good corrosion resistance. When producing medium particles with higher hardness or both particles and corrosive media, ceramics' advantages are unparalleled. They fully meet stringent requirements in chlor-alkali production, thus improving efficiency.
Conclusion
In summary, this study shows that structural ceramics represent a new type of ceramics in industrial production. These ceramics have structural advantages such as high hardness, high strength, outstanding insulation, high-temperature resistance, corrosion resistance, excellent antioxidant and impact resistance. In chlor-alkali production, ceramic valves are used in strong acid and strong alkali environment. They can remain stable due to their physical properties. With the continuous development of modern industrial production, structural ceramics do not have high requirements for production conditions. Even under harsh operating conditions, they can maintain the quality of industrial production products with stable mechanical properties. Currently, in many fields, structural ceramics have significant advantages and high popularity. In future industrial development, the progress of the ceramic industry will expand applications beyond the chemical industry, promoting ceramic technology and opening new avenues for China's industrial development.
