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℃.
