Method for producing an article for use in the foundry industry, corresponding mold, core, feed element, or molding material mixture, and devices and uses

Abstract

What is described is a process for producing an article for use in the foundry industry selected from molds, cores, feeder elements and molding material mixtures, and includes the following steps: (S1) producing or providing a binder system with the following components in three spatially separate vessels: a component (A) particulate amorphous silicon dioxide, a first liquid component (B) waterglass, and a second liquid component (C) aluminate ions dissolved in an aqueous phase, (S2) contacting a mold base material (D) and constituents of all the components (A), (B) and (C) of the binder system in predetermined ratios in one or more steps, so as to result in a molding material mixture in which the aluminate ions and the particulate amorphous silicon dioxide are mixed wholly or partly into the waterglass, wherein steps (S1) and (S2) are conducted in a facility for producing molding material mixtures. Also described are a corresponding molding material mixture and apparatuses and uses.
