Abstract

The invention discloses a non-arsenic composite oxide clarifying agent, which is prepared from the following components in percentages by weight: 9.5-15wt% of Sb2O3, 33.0-49.0wt% of Na2SO4, 40.0-55wt% of NaNO3, less than 0.006wt% of Fe2O3 and less than or equal to 0.35twt% of NaCl. The non-arsenic composite oxide clarifying agent has the characteristics that the clarifying agent used for low-iron, sodium and calcium silicate ultra-white rolled glass is redesigned and combined into a brand-new composite component, so that the feeding link is reduced, the ingredient weighing time is shortened, the manpower is saved, the labor intensity of a worker is reduced, the cost is reduced, more importantly, pollution to the environment caused by material flying is reduced, the hygroscopy of the material is reduced and the chemical stability of the clarifying agent is improved.

Description

technical field [0001] The invention relates to the technical field of production of low-iron sodium calcium silicate ultra-clear rolled glass, in particular to an arsenic-free composite oxidation clarifier. Background technique [0002] Ultra-clear (low-iron) soda-lime silicate rolled glass is widely used in the solar energy industry, among which, the main factor affecting the transmittance and whiteness of ultra-white (low-iron) soda-lime-silicate rolled glass is the iron oxide in the glass The form and content of the material, the iron oxides contained in the glass mainly include ferrous oxide (FeO) and iron oxide (Fe 2 o 3 ) two forms, ferrous oxide (FeO) can make the glass light blue-green, iron oxide (Fe2O3) can make the glass light yellow-green, the change between them is also reversible, that is, Fe 2 o 3 ⇌ 2FeO + 1 / 2 O 2 , under high temperature conditions and when there is a reducing agent, the content of ferrous oxide is dominant, making the glass appear light...
