Application of Cold Isostatic Pressing Technology
1. Application of cold isostatic pressing (CIP) technology in ceramic industry
Cold isostatic pressing technology has been widely used in various fields such as daily ceramics, industrial ceramics, and special ceramics. The most promising way to make ceramics with higher performance is to use the cold isostatic pressing process, in which the powder is first formed into a rough billet, which is then machined and sintered. Due to the use of forming molds made of elastic materials during cold isostatic pressing, rough blanks with complex shapes can be produced. With the addition of isotropic extremely high isostatic pressure, the press-molded blanks have sufficient In addition, it has the characteristics of small sintering shrinkage and near-net size. Therefore, the processing amount of the sintered product is significantly reduced, thereby reducing the cost of the product.
At present, from the daily ceramic products such as discs and dishes, to alumina grinding balls, alumina chemical filler balls, alumina plungers, aluminum titanate risers, ceramic radomes and other structural ceramics and functional ceramics, spark plugs, high High-voltage electric porcelain products such as frequency porcelain sleeves and vacuum arc extinguishers have widely adopted C IP molding technology.
2. Application of cold isostatic pressing (CIP) technology in powder metallurgy
Cold isostatic pressing technology is widely used to make carbide rolls with large size, complex shape and strict performance requirements, top hammers for synthetic diamond, carbide tools, etc. It is also widely used to form various powder materials with large height-diameter ratio, such as tungsten, high-speed steel, beryllium, aluminum and other rod-shaped and tubular blanks of different sizes and shapes, thus ensuring the performance of these materials and giving full play to powder metallurgy and cooling. The advantages of combining static pressure technology.
3. Application of cold isostatic pressing (CIP) technology in carbon graphite products
In the production of large-sized graphite rods, carbon resistance elements, graphite crucibles, brushes for motors and generators, graphite heating elements, graphite tubes for nuclear reactors, and rocket nozzles and other large-sized and special-shaped parts, the production of graphite products, cold isostatic pressing Molding technology has a wide range of applications.
4. Application of cold isostatic pressing (CIP) technology in food processing industry
It is used for low-temperature sterilization and inactivation of enzymes in food, using cold isostatic pressing and high static pressure treatment, which only affects the combination of non-covalent bonds in the molecular three-dimensional structure of proteins and enzymes, and affects other flavors, pigments, vitamins, etc. There is no impact, and the original taste and color of the food are maintained while sterilizing and inactivating enzymes. For example, the fruit juice after high static pressure processing maintains more than 95% of the vitamin content, while the fruit juice after thermal processing is only 72%~78%.
