Product Usage

Anhydrous Sodium Sulfite is an industrial chemical with strong reducing properties, playing a pivotal role as a "deoxygenator" and "preservative" across various production sectors. In water treatment, it is extensively used for deoxygenating boiler feedwater to prevent metallic pipe corrosion caused by oxidation. In the paper and textile industries, it serves as a bleaching auxiliary to remove residual oxygen and chlorine from fabrics and pulp, thereby protecting fiber strength. In the photography industry, it is an indispensable preservative in developing solutions, effectively preventing the oxidation of developing agents by air. Furthermore, it is utilized as a reducing agent in fine chemicals and serves as an antioxidant and preservative in the food industry for dried fruits and preserves to maintain their natural color.
