微生物发泡多孔陶瓷坯体的结构缺陷与改良措施探讨

DISCUSS ON DEFECT AND IMPROVEMENT FOR STRUCTURE OF POROUS CERAMIC BODY FOAMED BY MICROBE

采用微生物发泡法制备多孔陶瓷坯体容易产生孔隙不均匀、坯体开裂、收缩变形等结构缺陷,分析泥料增塑、微生物营养条件、改变泥料拌料参数、坯体收缩控制等改良措施,研究常温条件下制备孔隙均匀、形状规整、孔径分布范围较宽的多孔陶瓷坯体的微生物发泡方法,节省能源消耗。

Preparation of porous ceramic body foamed by microbe is prone to structure defects such as inequality of pore size and distribution,crack,contraction deformation,etc.Based on the analysis of improving above defect by adding plasticizer,conditionimg microbial nutrition,changing parameters of agitation, controlling contraction deformation,study the method of preparimg porous ceramic body with equal pore distribution,regular shape,wide range of pore size,foamed by microbe at ordinary tempreature to reduce the consumption of energy.
