The production process of zirconia ceramic cylinder liner usually includes the following steps:
1. Raw material preparation: Select high-purity zirconia powder as the main raw material, and add some other additives to improve the performance of ceramics.
2. Mixing: Mix zirconia powder evenly with additives to ensure uniform composition of the ceramic.
3. Molding: Using appropriate molding methods such as dry pressing, isostatic pressing, injection molding, hot die casting, flow casting, injection molding, plastic extrusion molding, colloidal solidification molding, etc., the mixed raw materials are made into cylinder liner blanks of the desired shape.
4. Degreasing and Glue Removal: For molding processes other than dry pressing, the plasticizers added must be removed after the product is formed, otherwise it will affect the quality of the produced product. The degreasing and glue removal method is usually used for removal.
5. Sintering: Place the degreased and gelatinized cylinder liner blank into a high-temperature furnace for sintering, to densify it and form a hard ceramic structure. The sintering temperature and time depend on specific material and process requirements.
6. Processing: Processing the sintered cylinder liner, such as grinding, polishing, etc., to achieve the required dimensional accuracy and surface quality.
7. Inspection: Inspect the processed cylinder liner, including testing for size, shape, surface quality, hardness, wear resistance, etc., to ensure that the product meets quality standards.
8. Packaging: Pack the cylinder liners that have passed inspection to protect them from damage during transportation and storage.
It should be noted that the specific production process may vary depending on different manufacturers and product requirements. In actual production, adjustments and optimizations need to be made according to specific situations to ensure product quality and production efficiency.
