Usage:
Zinc sulphate monohydrate has a wide range of uses in various fields. It is used as the feed additive, in chemical and defense industries, fertilizers, mineral processing, pharmaceuticals, rubber, electronics, printing and dyeing agents, bone glue clarifiers and protectants, electroplating, to prevent plant diseases and insect pests, in cooling water treatment, as well as in the production of viscose fibers and nylon fibers. In addition, it is also used as a raw material for the manufacture of zinc salts and zinc barium white, for cable galvanizing and electrolytic zinc in the electrolytic industry, as well as for wood and leather preservatives and the production of artificial fibers. Food-grade zinc sulphate monohydrate can also be used as a nutritional supplement (zinc fortifier).
