| Abstract: | The effect of boron-containing modifier on the properties of aluminum phosphate binder and heat-curing sand mold are studied. It is revealed that the compressive strength and the humidity resistance of aluminum phosphate heat-curing sand molds in low humid air are improved by adding the boron-containing modifier into the binder. The density and viscosity increase and the stability decrease with the increasing the boron-containing modifier. |
