The Binding Properties Of Kaolin

Adhesion refers to the ability of kaolin to combine with non plastic raw materials to form plastic mud masses and have a certain degree of drying strength. The determination of binding ability involves adding standard quartz sand (with a mass composition of 0.25-0.15 particle size fraction accounting for 70% and 0.15-0.09mm particle size fraction accounting for 30%) to kaolin. Judging its height based on its highest sand content when still able to maintain a plastic clay mass and its flexural strength after drying, the more sand is added, the stronger the binding ability of this kaolin. Usually, kaolin with strong plasticity also has strong binding ability.
