Recovery of Polymer Waste in the Production of Ceramics Veneer with a Self-glazing Effect

The results of studies on the development of the composition of the charge based on low-plasticity clay using waste products from the consumption of products made of unplasticized polyvinyl chloride are presented. In addition, boric acid as a flux and titanium dioxide as a source of the vitreous phase are introduced into the composition of the charge to obtain the effects of vitrification of the surface of ceramic particles and self-glazing of the surface of the samples. The dependences of the main properties of ceramics veneer on the ratio between the amounts of polymer waste and titanium dioxide with the introduction of 5% by weight of boric acid have been established. The quantities of charge components that ensure the energy efficiency of the developed ceramics while ensuring strength, water absorption and frost resistance at a level corresponding to the requirements for products for brick cladding of buildings and structures have been determined. The use of this composition expands the range and raw material base for the production of ceramics veneer, allow you to dispose of polymer waste at any degree of purity and destruction in sufficiently large quantities.
