Production method capable of increasing refractive indexes of float glass

Abstract

The invention relates to a production method capable of increasing refractive indexes of float glass. The production method includes uniformly mixing quartz sand, aluminum oxide, soda, calcium carbonate, magnesium carbonate, rubidium carbonate, strontium carbonate, niobium pentoxide, osmium dioxide and polyethylene wax with one another to obtain mixtures and then feeding the mixtures into a float glass melting furnace; melting the mixtures in the float glass melting furnace at the high temperature to obtain melt; clarifying and homogenizing the melt and then enabling the melt to flow into a work pool; enabling the melt to flow into forming tin bath from a trough in the work pool and forming a strap-shaped continuous glass plate; carrying out annealing working procedures and cutting working procedures on the strap-shaped continuous glass plate to obtain the float glass which is a finished product. The production method capable of increasing the refractive indexes of the float glass has the advantages that the refractive indexes of the float glass can be increased and can reach 1.611, and the content of bubble in the float glass can be reduced.

Description

technical field [0001] The invention relates to a production method capable of enhancing the refractive index of float glass, and belongs to the technical field of glass manufacturing. Background technique [0002] Float glass is widely used, divided into tinted glass, float silver mirror, float glass / automobile windshield grade, float glass / deep processing grade, float glass / scanner grade, float glass / coating grade, float glass French glass / mirror grade. Among them, float glass with visible light transmittance greater than or equal to 83% has a wide range of uses and broad market prospects. Lighting glass, precision electronics industry, special buildings, etc. [0003] However, the existing ordinary float glass with a visible light transmittance greater than or equal to 83% has a refractive index of 1.5~1.523, and the refractive index is limited. The optical requirements of high refractive index required in glass, imitation crystal products, lamp glass, precision electr...

Problems solved by technology

[0003] However, the existing ordinary float glass with a visible light transmittance greater than or equal to 83% has a refractive index of 1.5~1.523, and the refractive index is limited, which cannot meet the needs of high-end buildings, high-end glass processing and solar photovoltaic curtain walls, as well as high-end glass furniture and decoration. Glass, imitation crystal products, lamp glass, precision electronics industry, special construction and other fields require high refractive index optical requirements, which also affect its aesthetic effect
