| Abstract: | By taking EPS emulsion as main raw material, a new casting binder of non-coal molding sand was developed. EPS water-borne property by modification is fine, and available for the casting binder. The water-borne with Ca(OH)_2 powder addition by blowing CO_2 gas can get high efficiency gas-hardened resin sand. This binder has no phenol, aldehyde, sulphur, nitrogen, and has good collapsibility quality, high strength, good water-resistance, a smooth casting surface, and a wide application prospect so that it is suitable for (popularizing). |
