Alumina Ceramics:
Alumina ceramic dry pressing refers to a green body forming method commonly used in ceramic production. The powder is granulated by adding a small amount of binder, and then loaded into a mold, pressurized on a press, so that the powder is close to each other in the mold, and is firmly combined by internal friction to form a certain shape of the body. Induction heating surface heat treatment. Conventional methods include unidirectional compression, bidirectional compression (bidirectional simultaneous compression, bidirectional separate compression), four-way compression, and the like. Improved dry pressing includes vibration pressing and magnetic field pressing (suitable for metal powder). The advantages of dry press molding are high production efficiency, low labor, low rejection rate, short production cycle, high density and strength of the products produced, suitable for large-scale industrial production; the disadvantage is that the shape of the molded product is relatively limited, and the cost of the mold is high , The strength of the green body is low, the compactness inside the green body is inconsistent, and the uniformity of the structure is relatively poor. In the field of ceramic production, the products manufactured by the dry pressing method mainly include ceramic tiles, wear-resistant porcelain-lined ceramic sheets, sealing rings, and the like. In dry pressing molding, powder (5% to 8% moisture content) is put into a metal mold and compressed under the action of force (usually unidirectional pressure). The gas in the void in the blank is discharged and the particles are displaced. 4. Gradually move closer and bite into each other tightly, and finally form a body with the same cross-section as the mold, and the shape of the upper and lower sides is determined by the upper and lower indenters of the mold. The size of the L gap in the shaped body is significantly reduced, the number is greatly reduced, the density is significantly increased, and it has a certain strength.
High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
