Abstract
The method of continuous weighing is used to study the process of drying of corundum semiproducts plasticized by solutions of methyl cellulose, carboxymethyl cellulose, polyvinyl alcohol, and their mixtures as compared to porcelain semiproducts. In the 20–90°C temperature range the drying of oxide and clay-containing preforms is similar and does not depend on the nature of the temporary technological binder. The characteristic points of the semilogarithmic dependence of the moisture content on the drying time coincide with the points on the drying curve commonly used for analysis. The drying of preforms plasticized by PVA can be intensified by introducing polymer additives into the binder.
