“…It doesn't leave serious brush marks when brushing or have the problems of common water-based coating such as needing to dry, being difficult to dry, and easy to absorb moisture, etc. [1][2][3][4][5][6]. From the point of view of energy saving and consumption reducing, improving working conditions as well as production safety along with surface quality of castings and so on, water-based self-drying / fast-drying coating is the developing direction of sand casting coating.…”

Abstract:The article focuses on the self-drying curing characteristics of energy-saving and environmental friendly water-based self-drying / fast-drying foundry coating. Through check experiment, the differences of strength, humidity resistance and influence on the strength of resin sand when respectively using new water-based foundry coating, common water-based and alcohol-based coating are compared and studied. The results show that the coating strength of new water-based coating is significantly higher than that of common water-based coating and is almost the same as alcohol-based coating. The coating has a minimal impact on the strength of resin sand, and its humidity resistance is obviously better than that of common water-based and alcohol-based coating, for the residual water content of the coating is only about 1.4% after self-drying.

L ost foam casting, a near net shape and green casting technology, have various advantages, like high precision, high surface quality, environmental cleanliness, simple process and so on [1-4]. However, in ordinary sand casting, the foam would experience complex physical and chemical reactions with gasification and decalescence in the high temperature eff ect of molten metal during the fi lling process. These reactions will decrease temperature rapidly in the metal front and produce backpressure causing a huge impact on fi lling and even causing casting defects [5-8]. In order to further understand the fi lling mechanism of lost foam casting, a great number of studies have been made to explore the pyrolysis characteristics and thermal kinetics of diff erent kinds of foam patterns. Shivkumar S. et al. [9, 10] have investigated foam degradation of EPS and EPMMA since the 1980s. They used scanning electron
