Technological and Quality Aspects of the Use of Innovative Inorganic Binders in the Production of Castings

The production of cores for the pre-casting holes in castings places high demands on quality molding mixtures used. For this reason, organic binders are still used to a large extent, which, although they meet technological requirements, source pollutant emissions during castings. current trend towards greening is therefore looking suitable alternative ‘green’ inorganic binders. Although many decades standard could not be compared with resins terms properties, new binder systems currently being developed that can largely eliminate these disadvantages, which include, particular, significantly lower collapsibility and reclaimability, mechanical strength values. Last but least, use may limited by parameter shelf-life, main focus study. aim paper evaluate influence parameters core using generation their shelf-life. Shelf-life, defined as change wear resistance function exposure time given environment, evaluated under different climatic conditions.
