Abstract

The invention provides a low-temperature electric melting formula for transparent glass, a process method thereof and the transparent glass prepared through low-temperature electric melting formula and the process method. The transparent glass is prepared through the following steps: taking Cab-O-sil, boric acid, borax, calcite, primary zinc, barium carbonate, sodium carbonate and the like as main raw materials and sodium nitrate and the like as auxiliary raw materials, burdening, mixing, founding, molding and annealing. The transparent glass comprises the following main components by weight: 55-68% of SiO2, 0.01-0.05% of Fe2O3, 0.5-6% of B2O3, 0.5-3% of Al2O3, 3-8% of CaO, 0-5% of ZnO, 9-18% of Na2O, 2-10% of K2O, 1-10% of BaO, and 0-1% of Li2O. According to the invention, a technology of electric melting by a kiln is adopted, so that the melting temperature is lowered effectively, the energy consumption is reduced, and the quality of the transparent glass is improved. The formula and the process are suitable for manufacturing various glass crafts.

Description

technical field [0001] The invention relates to the technical field of production of glass craft products using an electric melting furnace for electric melting, and relates to R 2 O-RO-Al 2 o 3 -B 2 o 3 -SiO 2 system (where R 2 O represents alkali metal oxides, RO represents alkaline earth metal oxides and ZnO) low-temperature electric melting clear glass formula, process method and the clear glass made by using the formula and process method. Background technique [0002] With the excessive consumption of fossil energy and the intensification of environmental pollution, the production of high energy consumption and high emission enterprises is severely restricted. In order to reduce polluting gas emissions and improve the working environment of workers, the traditional coal-fired furnaces in the daily glass industry are gradually being replaced by electric melting furnaces. At present, the electric kiln technology at home and abroad is relatively mature, and is grad...
