近几年,由于卫生陶瓷注浆和成型工艺的机械化和自动化水平不断提高,自动化操作生产线投入使用,对石膏模型的要求也越来越高。如要求提高石膏模型的机械强度、耐热性、耐腐蚀性和使用寿命。所有这些因素都受石膏溶液及成型工艺的影响。苏联科研人员发现二水 In recent years, as the level of mechanization and automation of sanitary ceramics grouting and forming processes has continued to increase, and automated operation of production lines has been put into use, the requirements for gypsum models are also increasing. For example, it is required to improve the mechanical strength, heat resistance, corrosion resistance and service life of the plaster model. All these factors are affected by the gypsum solution and the molding process. Soviet scientists discover Di Shui
