Zirocnia Ceramics:
Demoulding: the process of taking out the blank from the model. The mastery of the demoulding point is a key. The demoulding is too early, the blank rest strength is not enough, the demoulding is difficult, and the blank is easily collapsed after demolding; the demoulding is too late, the billet is too late. Cracking occurs. Repairing: including a process of blanking, eye-opening and bonding. Traditional grouting method, the inner and outer surfaces of the blank after demolding are very rough. Generally, it needs to be repaired several times, and the work of bonding The amount is also very large. Modern use of high-strength plaster mold or resin mold, pressure grouting and other means, the workload of repairing the viscosity has been greatly reduced. The work of repairing, eye-catching and bonding needs to be carried out manually, and it is easy to appear waste, must master Good body moisture content. Drying: Pre-drying (also called semi-drying), that is, the moisture content of the green body is reduced from 15% to 17% (water content during bonding) to about 8%. Traditional pouring method, pre-pretreatment of the blank Drying is carried out naturally in the grouting workshop. During the 16 hours after the worker leaves work, the grouting workshop maintains high temperature (33~40 °C) and high humidity (40%-60%), making the blank slow. Dry. After pre-drying, the moisture content of the wet blank is reduced from 15% to 17% to 8% to 10%. Care should be taken to prevent waste due to excessive drying or uneven drying. The modern grouting method generally uses the hot air to directly dry the billet. The pre-drying shrinkage rate of the vitrified porcelain body is 4%, and the pre-drying shrinkage rate of the clay body is 2%. Secondary repair (repair): Yes The final process of slurry forming will finally determine the size of the blank. When the brush is used, the water content of the blank should be less, the water used for the blank should be less, and there should be no oil. After the body is repaired, it should be stored indoors at 28-35 °C. , ready to glaze.
