| Abstract: | A water-soluble foundry binder has been developed from modified potato starch. Preparing and hardening method of the core sand were determined by technological experiments, and the main properties, such as dry-tensile strength, wet-pressure strength, moisture absorption, gas evolution and collapsibility of the core sand were tested. The factors and rules of the effects on these properties were analyzed. The characteristics and methods to use the core sand were discussed. Some kinds of alloy casts were also produced by using the binder. |
| Keywords: | potato starch dry-tensile strength wet-pressure strength moisture absorption |
