Coated limestone in PVC products

Abstract

Laboratory researches of possibilities of getting coated limestone which is using like filler and producing PVC products was in two phases: - first phase is getting coated limestone - second phase is checking the degree of coating Like a start row material was used the limestone from the deposit "Vencac" Arandjelovac. The results of the experimental researches showed very successfully coating the surfaces of the particles by stearic acid (content 3 %) is making in vibration mill with rings, during which is releasing the degree of coating min 95 %. Checking the degree of coating is made by microscope way and immersion method (immersion of waters).
