Investigation of Antiadhesion Coatings for the Sag Bending of Silicate Glass

Abstract

In the article, the features of the interaction of different forms of carbon with various solvents are investigated comprehensively, and the nature of defects and their effect on the optical and physicochemical properties of coatings are studied. The compositions of high-temperature antiadhesion parting mixtures for sag bending which are based on the high-temperature lubricants of carbon-containing materials are investigated. Base on the research, the mechanisms of the coagulation of particles during heat treatment, the effect of the structure and particle size of the studied mixtures on the coating quality, and the interaction with binders were studied, which made it possible to obtain high-temperature antiadhesion coatings with predetermined characteristics. The technology of applying these mixtures on the surface of glass billets and removing them from the glass surface, while meeting the environmental safety requirements, is developed.
