The secret of the cup cup customization | Win-Win

March 01, 2023

The customization of the bone porcelain cup is the most complicated process. From the material to the burning into any process, it is slightly ignored, which may cause defects and even scrap. Some of these defects found that before burning, some were just exposed in the firing before burning, and some were simply formed due to improper firing. Because it becomes wrong, the production environment of each kiln is not similar, so it is difficult to make a comprehensive and applicable processing plan.




Cracking refers to a crack of different sizes in the finished product. The reason is that the dumpling of the body is too high (greater than 2 %), and the preheating ascending soft cooling is too fast, causing the compression of the finished table to be uneven. Some are internal injuries that the body has been collided before the mantle. The thickness of the blank body is uneven, and the amount of accessories (such as pots, tatto, etc.) is too large or poorly bonded.


The method of preparation is: (1) The body of the kiln must be dried up; (2) the set is strict with strict setting when installing the kiln, and the pads are consistent with the formula of the body. The size, weight and bonding position of the accessories are appropriate. Some enters 10-15 % of the glaze in the adhesive mud, which can make the nozzle and fuse with the subject, and the cloud can be reduced to cracking defects.




There are two types of burning finished products: "bubble" and "glaze foam". Bully bubbles are divided into two types: "oxide bubble" and "restoration foam". The surface of the oxidation finger bubble covers the glaze layer, and the section is gray and black, and it is mostly formed in the low temperature of the kiln. The important thing is that the lapse of the porcelain tire and glaze guess failed to be fully oxidized, and the burning matter was not completely removed. The heating temperature is fast, the temperature of the kiln is too low at the end of the oxidation cutting stage, and the temperature in the kiln is too low at the end of the oxidation, and the temperature difference is too large. In guessing, carbonate. More sulfate and organic impurities are the main cause of product foaming. Other fashion kiln density and high water in the kiln must also be paid attention to. The recovery bubble is also called partial foam, which is broken and yellow, and most of the finished products that occur at high temperature near fire. The key is that the sulfate in the blank body cannot be reappeared from the high -priced iron, and the strong reunion of the original air is not as good as that of the firing temperature. The glazed foam sedimentation charcoal and cutter failed to burn to volatilize before the glaze melted, and the gas was blocked in the glazed layer. If you extend the glaze to melt the light or burn it right, you can handle it.
