Preparation and Properties of Green and Environmentally Friendly Inorganic Foam Sand
By adding the foaming agent,the foaming promoter to the WJ-1 inorganic binder,and adding FT-1 additive during sand mixing,a green and environmentally friendly inorganic foaming sand with higher strength and excellent sand cleaning performance was obtained.It was then added to the preheating mold by extrusion to harden,forming a hollow sand mold(core).After casting,the sand mold(core)has excellent collapsibility,and the removal of sand molds can be achieved through low-cost and simple methods such as vibration and airflow,eliminating the complex sand cleaning methods such as crushing,heat treatment,sandblasting,etc.and simplifying the postprocessing processes of sand casting.
