Mold modelling method and the core for casting which use the dry aggregate blend and that dry aggregate blend

摘要

Binder being heated the 1st, offering the dry aggregate blend which does not generate the unpleasant odor and the gas which exerts adverse effect on the human body, the aggregate blend of the 2nd binder and the particle condition aggregate to detail of the space for mold modelling offering the mold modelling method of being possible to fill up sufficiently, the 3rd binder and the modelling mold which models the aggregate blend of the particle condition aggregate it designates that the mold modelling method of being possible to maintain sufficient character, under high humidity is offered as purpose. While mixing the water soluble binder and the aggregate blend which consists of the water, into the granular aggregate, heating, it decompresses or ventilates the moisture which is included in aforementioned aggregate blend and, evaporates and, it is the method of modelling the mold which adds lubricant and the building a bridge medicine to monad making use of the dry blend which is converted.
