On the Factors Affecting the Strength of Resin-coated Sand at Room Temperature

摘要

This paper deals with factors affecting the strength of hot process resin coated sand under room temperatures. The following factors which show influence on room-temperature tensile strength and bending strength were studied: the graininess, the distribution and the grain shape of base sand, phenolic resin, curing agents, additives and cooling procedure. The results may be used as a reference to preduce resin-coated sand.
