Use Sodium chlorite is a high-efficiency oxidant bleach. Mainly used for cotton spinning, linen, pulp bleaching, food disinfection, water treatment, sterilization and algae killing, and fish medicine manufacturing. The theoretical effective chlorine content of sodium chlorite is 157%, and industrial products with a purity of more than 80% have an effective chlorine content of 130%, which is equivalent to 7 times that of bleaching powder. Sodium chlorite is mainly used for bleaching of pulp, paper and various fibers such as flax, hemp, cotton, reeds, viscose fibers, etc. Because of its moderate redox potential, it is used for bleaching synthetic fibers (such as washing), natural fibers (such as plant fibers such as cotton, linen, mulberry, and pulp) and artificial fibers (such as rayon). It can remove pigment impurities without damaging the fiber, so you can obtain higher quality bleached products, which is incomparable with hydrogen peroxide and other chlorine-containing bleaches. With the continuous improvement of people's understanding, especially as the fourth-generation disinfectant, chlorine dioxide is further used in medical and health, food processing, aquaculture, drinking water disinfection, industrial water treatment and dried flower technology, etc., sodium chlorite drinking Water treatment, in addition to sterilization, algae killing, disinfection, also has a deodorizing effect. For water quality contaminated with phenol or phenol compounds, after treatment, phenol and phenol compounds can be removed. In addition, sodium chlorite can also be used in the bleaching and refining of sugar, flour, starch, oils and waxes, as well as the surface treatment of certain metals, and discharge agents for indanthrene dyeing.
