【Abstract】 A new modified phosphate inorganic resin binder, which can be applied in foundry industry and make no harm to environment, is studied in this paper. After being modified, the binder has excellent humidity resistance and is very steady when it is stored over a year. The sand molds or cores bonded by the binder have good collapsibility after casting.更多还原
