1 Production process
Zirconia ceramics forming a dry pressing, isostatic pressing, casting, hot pressure casting molding, tape casting, injection molding, plastic extrusion, colloidal solidification molding. One of the most widely used is the injection and dry press forming.
(2) Skim rubber removal
In addition to the stem pressure based on molding technology, other molding products to skim rubber discharging processing before entering the furnace sintering, because in addition to dry pressing and other technology in molding in zirconium powder, adding a certain proportion of plasticizer, the plasticizer in moulding must be removed, otherwise will on the sintering products caused serious quality influence. Superplasticizer mainly for paraffin wax and other polymeric materials which require such material, at a certain temperature shows that it has good plasticity and fluidity, at room temperature to a certain toughness and strength.
In structural ceramics, zirconia ceramics with high toughness, high bending strength and high wear resistance, excellent insulation properties, thermal expansion coefficient close to steel and other advantages, it is widely used in the field of structural ceramics. In the functional ceramic, its excellent high temperature resistant performance as the induction heating pipe, refractory materials, heating elements use. In addition, zirconia thermal barrier coatings, catalyst carrier, medical, health, refractory materials, textile and other fields are widely used.
