Problems solved by technology

As the content of ferrous oxide in the glass increases (chemical reduction of ferric oxide), the infrared absorption increases and the ultraviolet absorption decreases. At the same time, the color of the glass changes from yellow or yellow-green to blue-green, but the visible light transmittance of the glass also decreases.

Abstract

The invention relates to high-transmittance infrared-resistant energy-saving colored glass, which is turquoise blue glass and comprises the following components in percentage by weight: 64 to 77 percent of SiO2, 0.4 to 3 percent of Al2O3, 7 to 12 percent of CaO, 1 to 7 percent of MgO, 12 to 16 percent of Na2O, 0.05 to 1.0 percent of Fe2O3 and 0.5 to 10 percent of a compound reducing agent. According to the invention, the sodium-calcium-silicon float glass is taken as a basic composition, the composite reducing agent is added, and the reducing gas is introduced into the molten glass through accessory equipment of the melting furnace, so that the reducibility of the batch and the molten glass is increased under the combined action, Fe < 3 + > is reduced into Fe < 2 + >, the content of Fe < 2 + > in a glass finished product is obviously increased, and the infrared-resistant energy-saving performance of the glass is improved.

Description

technical field [0001] The invention relates to an anti-infrared glass, in particular to a high-transmittance anti-infrared energy-saving color glass and a melting device thereof. Background technique [0002] The best choice for building or automobile windshield is energy-saving glass. To make glass energy-saving, it must block infrared rays. Infrared rays (especially far-infrared rays) have a strong thermal effect and can resonate with most molecules. Phenomenon, converting light energy (the energy of electromagnetic waves) into molecular internal energy (heat energy), the heat of the sun is mainly transmitted to the earth through infrared rays, and the cheapest material in glass that can block infrared rays is divalent iron. As the content of divalent iron ions increases, the ability or heat absorption of glass to absorb infrared rays is enhanced, while ferric ions do not have this characteristic. Iron is usually in the form of ferrous oxide (FeO) and iron oxide (Fe 2 o...
