Original Title: An Important Link in Ceramic Forming — — Brief Introduction to Degreasing Process Degreasing is a process in which the organic matter in the molding body is removed by heating and other physical methods, resulting in a small amount of sintering.  The bonding system is generally composed of polyformaldehyde resin and stabilizing additives. Catalytic degreasing is a direct gas-solid reaction. The reaction temperature is generally 110 ~ 150 ℃, which is lower than the melting point of polyformaldehyde resin to prevent the formation of liquid phase. In this way, softening of the green body due to the formation of a liquid phase during thermal debinding, or deformation and defects due to the influence of gravity, internal stress, or viscous flow, are avoided. Therefore, its biggest advantage is that it can control the defects of the green body very well, and it is suitable for making large-size products. The invention has the advantages that the degreasing speed is high, the deformation and the defect of the green body are less, the precision is high, and the invention is more suitable for preparing large-size or thick-section ceramic products, such as ceramic nozzles, bearing balls, automobile decorative parts and the like; Disadvantages: special binder, decarboxylation after extraction ,nutsche filter dryer, feed preparation is difficult, liquidity is poor, the cost is high,  Ltd.
