Mud refining and blank drawing technology for disinfecting tableware

Each production process of disinfection tableware cannot be intuitively understood. Next, let's talk about the mud and drawing process. 1. Practice mud: take porcelain stone from the mining area, first break the lump to the size of an egg with a hammer manually, and then use the water margin to make it into powder, wash it and remove impurities, after precipitation, it is made into brick-like mud. Then mix the mud block with water to remove the dregs, rub it with both hands, or step on it with feet to squeeze out the air in the mud mass and make the water in the mud uniform. 2. Drawing blank: throw the mud ball at the center of the turntable of the windlass, and pull it out by flexion and extension to make the general appearance of the sterilized tableware blank. Drawing blank is the first process of forming. First of all, we should be familiar with the shrinkage rate of mud for drawing blank forming, and the total shrinkage rate is roughly 18- 20%, according to the size of the variety and different types of equipment and the hardness of the clay to be placed ruler. Due to the softness of porcelain clay, the blanks drawn are thicker than those made of other clay. The drawing blank should not only pay attention to the shrinkage, but also pay attention to the shape. In case of large-sized products, they should be drawn in sections. From each section, we can see the skill and level of the drawing master. The manufacturing process of sterilized tableware is accumulated from our history. The process includes many details. I hope the above details will be helpful to you.
