高塑性泥料因其良好的可塑性,可用于生产大尺寸日用瓷制品.然而,大尺寸高塑性泥料在干燥过程中由于不均匀的干燥速率形成收缩各向异性,易导致内部应力积累与裂纹形成.本文利用兼具保水性、分散性、润滑性的复合粘结剂制备了高塑性泥料,并结合干燥控制工艺系统地研究了泥料尺寸和环境温度对干燥效果的影响,建立了泥料尺寸-干燥温度-失水率之间关系.研究结果表明,经添加复合结剂的泥料具有高塑性,具有生产大尺寸陶瓷制品的能力,且在 110℃环境温度下干燥内可获得无开裂、稳定的大尺寸泥料.
High-plasticity mud can be utilized to produce large-sized daily porcelain products due to its favorable plasticity.However,during the drying process,large-sized and highly plastic mud materials exhibit shrinkage anisotropy resulting from uneven drying rates,which can lead to the accumulation of internal stress and subsequent crack formation.This paper employs a composite binder with water retention,dispersion,and lubricity to prepare highly plastic mud,and integrates the drying control process to systematically investigate the effects of mud size and ambient temperature on the drying outcome.Furthermore,it establishes the relationship between mud size,drying temperature,and water loss rate.The research findings indicate that the mud with the added composite binder demonstrates high plasticity and the capability to produce large-sized ceramic products.Additionally,a stable large-sized mud free from cracking can be achieved after drying at an ambient temperature of 110℃.
