Effects of Different Sodic Deflocculants on Rheological Properties of Acid-Resistant Overglaze Slip
This paper aims at solving the poor rheology of clay-water- acid-resistant overglaze slip. Natronite, tripolyphosphate sodium and composite deflocculant compounded of sodium natronite and sodium tripolyphosphate in proportion of 1:2 respectively were taken as deflocculants, and single-factor test and ring test were used to measure the variations in zeta-potential, viscosity and thixotropic. The results show that 0.3% of the composite deflocculants are better than any other single deflocculants on clay-water-acid-resistant overglaze slip, which has a better liquidity, a better thixotropy and a better stability that can avoid defects on glaze such as crawling, pinhole, hard spot, focal spot. Some factual and theoretic bases can be provided for enamel industry.
