Study of Adaptability of the Compound of Sulfonate Acid Water Reducing Agent with Ceramic Slurry Blank

Abstract:

In this study, we investigate the effect of four types of water reducing agen on fluidity, suspensibility, thixotropy and the particle size of ceramic slurry and analyze the corresponding mechanism. Those water reducing agen include Lignin sulfonate water reducing agent, Sodium metasilicate, naphthalene sulfonate formaldehyde condensate, and the inorganic compound reducing agent. Experiment results shows that the relative molecular mass, the structure of water reducer, the content, and the moisture content of ceramic blank particle can play an important role in the adaptability of both water reducing agen and ceramic slurry. We make a mixed water reducer with lignin sulfonate, sodium metasilicate, and naphthalene sulfonate formaldehyde condensate by the corresponding appropriate mass ratio: 3:2:1. Then we add the mixed water reducing agen by the total dosage of 0.6% into the designed ceramic castable. We find that the performance of the slurry is considerably better improved by the mixed water reducing agen than by either a single one or by the currently commercial inorganic compound reducing agent, such as better improvements in liquidity, the slurry particle size, the mechanical strength of dry body, and the damage strength of porcelain body.
