Product Introduction:
At room temperature, Zinc Sulphate Heptahydrate is a white particle or powder and orthogonal crystal, which has good convergence. It is a commonly used astringent, will be weathered in dry air. It is soluble in water, slightly soluble in ethanol and glycerin. It is mainly used as the raw material for manufacturing zinc-barium and other zinc salts, as well as the important auxiliary raw materials for viscose fiber and nylon fiber, etc. It is also used as mordant for printing and dyeing, wood and leather preservative bone glue clarification and preservation, emetic agent for medicine and fungicide, and microelement fertilizer for agriculture and so on.
