    Composition, synthesis and properties of color architecture building foam glass obtained from waste packing glass
    (2013-05-21) Lakov L.; Toncheva K.; Staneva A.; Ilcheva Z.; Simeonova T.
    The foam glass is known mainly as an insulation material. It is less popular for the production of industrial colored foam glass. This material is for the application as coatings for building, architectural and artistic elements, especially in interior design. The synthesized compositions contain different coloring and foaming components. New foaming agents are characterized with dual function, both for foaming and coloring. By present study some environmental problems are solved for utilization of waste glasses to obtain a color foam glasses for use as heat and sound insulation. The obtained results are a part of a more general project for the development of technologies and special equipment for production of foam glasses.

    Composition, synthesis and properties of insulation foam glass obtained from packing glass waste
    (2013-05-21) Lakov L.; Toncheva K.; Staneva A.; Simeonova T.; Ilcheva Z.
    So far, the starting compositions for obtaining foam glass have been developed based on glasses pre-synthesized for the purpose. From the point of view of such important issues as increasing the energy efficiency and utilization of municipal and industrial waste, the possibility for production of foam glass insulation out of packing glass waste is a very good alternative. The present study to suggest a decision for utilization of waste glass and serves as a basis for developing the technology for production of continuous strip of foam glass material. This technology will be implemented in vertical production installation, which is currently under construction.

    Modeling of the thermo physical parameters of material in the foaming zone in equipment for continuous band of foam glass
    (2015-01-01) Toncheva K.; Staneva A.
    Modeling of the thermo physical properties of the material in the foaming zone of an installation for continuous band of foam glass manufacture is presented. The initial physical assumptions concerning the implementation of the process are pointed out. The changes of properties like density, thermal conductivity, and specific heat capacity of the foamed material, i.e. a mixture of glass powder and foamers are followed in the course of the heating process.

    TECHNOLOGICAL APPROACH FOR PRODUCTION OF SILICATE INSULATING MATERIALS AND PANELS FOR THE DECORATIVE CLADDING OF BUILDINGS
    (2023-01-01) Toncheva K.; Jivov B.; Lakov L.; Staneva A.
    A conceptual model of an industrial unit for experimental application in a production environment of a technology approach developed in laboratory conditions for the production of various silicate composite materials has been developed. The separate production sections specialized for the implementation of different stages of the technological process and the necessary standard and innovative technical equipment are considered. The specific characteristics of the various products and the existing potential opportunities for their application in different areas of construction are analyzed. The presented technological methodology allows efficient utilization of waste silicate raw materials and cost-effective production of various thermal insulation materials and colored decorative panels for cladding buildings.
