Silent-free thermal insulation from self-sealing masses based on a burnable additive of plant origin. Part 2. Mineralogical, chemical, and biological characteristics of a burn-out additive and their manifestation during electrohydrothermal force treatment of the molding material

Abstract

Refractory clay and water in a confined space are in a force field arising from the active swelling of a plant-based starch-containing additive. During self-compaction, shrinkage moisture is absorbed by the plant additive and squeezed into clay particles. It has been established that the technological properties of the additive are affected by the mineralogical, chemical, thermodynamic and structural features of starch. Water-soluble substances contained in starch form a paste, which increases the strength of raw. A physical model of the molding compaction mechanism is proposed. Ill. 2.
