INVESTIGATION OF INFLUENCE OF COMPLEXACTIVATION ON RHEOTECHNOLOGICAL CHARACTERISTICSOF CERAMIC MASSES

Abstract

in the work, rheological characteristics of ceramic masses based on loam with ash, mechanical-and complex activated loam with ash are investigated.Joint mechanical activation of loam with ash was carried out in a mixer-activator, operating on the principle of a centrifugal impact mill. Complex activation includes joint mechanical activation of loam with ash, followed by treatment with surface active additive -PO-PB-7 in an amount of 0.1%.When determining the plastic strength of the masses on the basis of mechanical-, complexlyactivated and non-activated (original) loam with ash (in an amount of from 0 to 75%), optimal compositions of the masses were found.It was found that the plastic strength of the complex activated ceramic masses increases. The coefficient of sensitivity increases in mechanical-and complexly activated loams, and decreases with the introduction of ash, which predetermines the possibility of intensifying the drying process of samples based on complexly activated clay-ash mass.It has been established that the masses on the basis of complexly activated clay-ash raw turn into structural-mechanical type I with improved rheological properties
