High-water-permeability blue glass based on float process and production method of high-water-permeability blue glass

Abstract

The invention provides high-water-permeability blue glass based on a float process and a production method of the high-water-permeability blue glass, and belongs to the field of glass production. The production method comprises the following steps of: weighing float glass production raw materials, the raw materials containing a predetermined amount of quartz sand; on the basis of the glass production raw materials, weighing a predetermined amount of cobaltic oxide powder and manganese dioxide powder as a coloring agent; respectively mixing the coloring agent with the quartz sand to obtain a diluted coloring agent; and by taking the diluted coloring agent as a raw material component, jointly carrying out float glass production feeding on the diluted coloring agent and the weighed glass production raw materials, and carrying out founding, clarifying, forming, annealing and post-treatment to obtain the high-water-permeability blue glass. If necessary, an oxidant of the coloring agent is added. According to the invention, physical decoloration and coloring of the glass are realized on the premise of keeping high transmittance, the high-water-permeability blue glass is produced by adding the coloring agent in a dilution manner and slightly adjusting color space parameters, the service life of a melting furnace production line is prolonged, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of glass production, and in particular relates to a highly water-permeable blue glass based on a float process and a production method thereof. Background technique [0002] The production process of float glass is the most important production method of flat glass. According to the glass composition system, it is divided into soda-lime glass, borosilicate glass, alkali-free aluminoborosilicate glass, alkali-aluminosilicate glass, etc., of which soda-lime glass is the total production and The largest glass variety. Soda-lime glass is widely used in photovoltaic curtain walls, glass furniture, decorative glass, imitation crystal products, lamp glass, copy scanner panels and other fields. In the photovoltaic and electronic industries, the most important parameter for the application of glass components is the transparency of the glass, which usually requires high transparency. [0003] In the prior art, among the soda...

Problems solved by technology

However, the production of ultra-clear glass is extremely demanding on raw materials, but it is difficult to obtain a large amount of low-iron (iron oxide less than 100ppm) quartz sand in raw material production, which usually contains higher iron impurity content (iron oxide is less than 300ppm), and The source of raw materials is unstable due to different origins; in order to strictly control impurity ions in the production of float glass, the process of removing impurities or changing the valence state of iron ions is more complicated, resulting in a substantial increase in the cost of high-transparency glass
