Application of high-modules sodium silicate modified with stabilizer as the mould and core binder, instead of ordinary low-modules sodium silicate is a new way to improve the properties of sodium silicate bonded sand. Compared with all kinds of amylums as stabilizer in stabilizing effect, the wheat flour is considered to be best one. Therefore, the storage stability of high-modules sodium silicate binder modified with wheat flour and the moulding (core) mixture are increased, the strength and surface stability...
