Prediction of water absorption of nonglazed tiles made by semidry molding using a regression model

Abstract

The possibility of predicting water absorption in semi-dry molding of ceramic tiles using data on linear dimensions of molded tiles and their firing regime is considered. An empirical formula is given, which makes it possible to estimate the quantitative effect of tile sizes, molding pressure, and firing parameters on the variations in water absorption. The possibility is demonstrated for predicting water absorption in tiles 40–50 min before they leave the firing furnace.
