Abstract: Influence of the ratio of raw materials on the extrusive property and drying performance of the terracotta panel was investigated by the thermo-gravimetry, differential thermal analysis (TG-DTA) and SEM methods. The results show that the optimization extrusion property of paste body and drying behavior can be achieved by the ratio of plastic and non-plastic materials is 45:55.

Abstract: The extrusion property of the paste has a significant effect on the production of terracotta panel. The influence of sodium carbonate addition on the exchange ability of ions, thickened hydrate film with the sodium cations and the plasticity of mud pie was investigated. When the addition of sodium carbonate is 0.015%wt, the plasticity and yield strength of paste are excellent. The best performance specimen with 0.015% sodium carbonate has a few fluctuation of effective strain and the ratio of the maximum with the minimum velocity of paste is the least while extruding from meatus of discharging.
