Isostatic Graphite
Isostatic graphite is a new type of graphite material developed in the 1960s and has a series of excellent properties. Compared with ordinary graphite, the structure is fine and dense, and the uniformity is good; the thermal expansion coefficient is very low, and it has excellent thermal shock resistance; isotropic; strong chemical corrosion resistance, good thermal and electrical conductivity; excellent mechanical processing performance. It is precisely because of this series of excellent properties that isostatic graphite is widely used in metallurgy, chemical, electrical, aerospace and atomic energy industries.
Isostatic Pressing and Isostatic Pressing
Isostatic pressure: refers to the simultaneous application of equal pressure to the sealed material in all directions;
Isostatic pressing: The material to be pressed is sealed and placed in a high-pressure container, and the material is uniformly pressurized from all directions by using the incompressible properties of the liquid medium and the property of uniformly transmitting pressure. When the liquid medium is injected into the pressure through the pressure pump According to the principle of fluid mechanics, the pressure of the powder in the high-pressure container is uniform and uniform in all directions. Using the above method to densify the powder into a green body is called isostatic pressing.
Isostatic graphite:
Isostatic pressing graphite refers to graphite materials produced by isostatic pressing. Due to the uniform pressure of the liquid pressure during the molding process, the obtained graphite material has excellent properties, including: large molding specifications; uniform structure of the blank; high density and high strength; isotropy (characteristics and size, shape, sampling direction) and other advantages, so isostatic graphite is also called "isotropic" graphite.
