Prediction of water absorption in nonglazed tiles of semidry molding using regression model

The possibility of predicting water absorption in the production of semi-dry pressing ceramic tiles by using data on the linear dimensions of the pressed tiles and their firing modes has been investigated. An empirical formula is given that allows one to quantify the effect of tile size, pressing pressure and firing parameters on the change in water absorption. The possibility of predicting water absorption 40 - 50 minutes before the exit of the tiles from the firing furnace is shown. Table 1, ill. 2, bibliography: 5 titles.
