1. Isostatic pressing and isostatic pressing molding
Isostatic pressure: refers to the state of applying equal pressure to the sealed material in all directions at the same time.
Isostatic pressing: The material to be pressed is placed in a high-pressure container after being sealed, and the material is uniformly pressurized from all directions by utilizing the incompressible properties of the liquid medium and the property of uniformly transmitting pressure. When the liquid medium is injected into the pressure vessel through the pressure pump, according to the principle of fluid mechanics, its pressure remains unchanged and evenly transmitted to all directions. Therefore, the pressure on the powder in the high-pressure container is uniform and consistent in all directions. The method of using the above method to densify the powder into a green body is called isostatic pressing.
2. Isostatic graphite
Isostatic graphite refers to graphite materials produced by isostatic pressing. Due to the uniform and constant pressure of liquid pressure during the molding process of isostatically pressed graphite, the graphite material produced has excellent properties and has the following advantages: large molding specifications; uniform blank structure; high density and strength; isotropic (characteristics have nothing to do with size, shape, and sampling direction). Therefore, isostatically pressed graphite is also called "isotropic" graphite.
