OBTAINING BINDING MATERIALS FOR MOLDS AND CORE FOUNDRY PRODUCTION BASED ON LOCAL RAW MATERIALS

Abstract

In the research work, to obtain modified starch and establish the chemical structure, chemical and thermal analyzes of the initial raw materials and products based on it were carried out, modern physicochemical methods of analysis were used, including IR spectroscopy, elemental, differential thermal (DTA) analyzes and extrusion. The developed binding materials based on local modified technical starch for the production of molding and core products have a number of advantages compared to other traditional ones.
