Related knowledge of expansion coefficient of disinfection tableware

Disinfection tableware is designed based on the principle of 'use first and decoration second'. Its expansion coefficient has an important influence on mechanical strength and determines whether cracks will occur. 1. Through monitoring the expansion coefficient of the body and glaze of the disinfected tableware, the curve characteristics of the expansion coefficient of the glaze and the blank are found. 2. At 600 ℃ ~ In the stage of 700 ℃, the difference of expansion coefficient between the blank and glaze of the sterilized tableware is relatively large. By properly adjusting the expansion coefficient of this temperature section, the difference of expansion coefficient of the blank glaze can be narrowed, in order to improve the adaptability of blank glaze and thus improve the deformation. 3. The results show that the expansion coefficient of glaze for disinfection tableware can play a better role in reducing the deformation of tableware. With the quickening pace of life, people's requirements for disinfection tableware are getting higher and higher, and cracking resistance and good quality are more popular.
