Abstract
The present invention discloses a glass, wherein the main raw material contains quartz sand, soda ash, calcite, feldspar, carbon powder and an active agent, and the active agent mainly comprises 8-11% of SiO2, 12-19% of an active oxidant, 0.1-3% of Al2O3, 12-16% of Na2O, 20-28% of CaO, 30-40% of a volatilization substance, and 0.01-1% of Fe2O3. The invention further discloses a preparation method for the glass. The preparation method comprises: weighing materials according to the formula; adding the materials to a melting kiln, and melting at a temperature of 1500-1650 DEG C to prepare molten glass; carrying out a molding treatment on the molten glass; and carrying out an annealing treatment on the molten glass to obtain the glass. According to the invention, the glass does not contain sulfur, fluorine and toxic components, the emission can not pollute the environment, characteristics of environmental protection and energy saving are provided, the food safety is ensured, production efficiency is efficiently increased, and energy consumption is reduced.
Description
technical field [0001] The invention relates to the field of glass manufacturing, in particular to a glass and a preparation method thereof. Background technique [0002] With the vigorous development of national environmental protection, energy saving and consumption reduction, glass production has also launched glass production flue gas treatment projects (such as "desulfurization"), but this project is expensive, high in operating costs, and will generate other wastes and pollute The environment needs to be reprocessed to achieve the real environmental protection purpose. At present, the prior art generally adopts the following formula: [0003] 1. Glauber's salt formula for bottles and cans: This is the most widely used formula for bottle and can glass production. It uses Glauber's salt as a clarifying agent, and releases gas after high-temperature reaction in glass production to achieve a certain clarification effect. "Glass Technology" (China Light Industry Press, 1s...
