Method for the production of glass foam products under recycling of a scrap glass mixture

摘要

The present invention relates to a method for the production of glass foam products under recycling of a scrap glass mixture comprising image screen glass of television sets, computers or other monitors as well as glass of fluorescent tubes and / or energy-saving lamps and / or photovoltaic devices, comprising the method steps which are executed in the following sequence:• a separate grinding of individual fractions of the scrap glass, which originate from various sources, to ground glass,• Mixing of a glass intermetallic mass of content of the various glass flour fractions and an activator without the addition of water or other liquids and in the dry method• thermal treatment of the glass intermetallic compound, wherein the glass mass interference first to a sintering process and later is subjected to a foaming process, in the case of temperatures in a temperature range from 850°C. 890°C, and the resulting glass foam product is subsequently cooled.In accordance with the invention, the thermally sintered glass powder and activator composite glass intermetallic compound with a weight proportion of 85 – 99 percent, of the image screen glass and glass of the fluorescent tubes and / or energy-saving lamps and / or photovoltaic devices, at least to 10 percent proportion by weight of image screen glass.
