Sodium Metabisulphite, Sodium Sulphite Anhydrous, Zinc Oxide, Titanium Dioxide

Use of anhydrous sodium sulfite: pulp bleaching agent; chemical fiber stabilizer; fabric bleaching agent; dyeing and bleaching industrial deoxidizer; chemical industry reducing agent and sulfonating agent; leather; used in printing and dyeing industry as dechlorination agent and bleaching agent. It is used for the scouring of various cotton fabrics to prevent local oxidation of cotton fibers and affect fiber strength. The photographic industry is used as a developer, and the organic industry is used as m-phenylenediamine.

Titanium dioxide has been used as a bleaching and opacifying agent in porcelain enamels, giving them brightness, hardness, and acid resistance. In modern times it is used in cosmetics, such as in skin care products and sunscreen lotions, with claims that titanium dioxide protects the skin from ultraviolet radiation because of its property to absorb ultraviolet light.

Titanium dioxide has superior pigment properties such as high color loss, high hiding power, high reflectivity, and low specific gravity, and is the best of white pigments. The lattice of rutile titanium dioxide is denser than that of anatase titanium dioxide, which is relatively stable, has good weather resistance, water resistance and is not easy to yellow, and is not powdered, but has a slightly lower whiteness and is suitable for outdoor use. pigment. Anatase titanium dioxide has a large lattice space, is relatively unstable, has poor weather resistance, is easy to yellow, and is easy to be pulverized, but has a high whiteness and is suitable for the production of indoor pigments.
