Chemical Properties£º
Pure zinc sulfate in the air long storage yellowing, loss of water in a dry air from a white powder. There are a variety of hydrates: in the range of 0-39 ℃ and water stable equilibrium seven water zinc sulfate hydrate, within 39-60 ℃ 6 zinc sulfate, in the 60-100 ℃, co***red with zinc sulfate monohydrate. When heated to 280 ℃ completely lost when various hydrate crystal water, 680 ℃ when the decomposition of oxygen zinc sulfate, further decomposition above 750 ℃, and finally decomposed into zinc oxide and sulfur trioxide at about 930 ℃. ZnSO4 ¡¤ 7H2O and MSO4 ¡¤ 7H2O (M = Mg, Fe, Mn, Co, Ni) in a certain range to form a mixed crystal. With a base to generate precipitate zinc hydroxide, barium sulfate precipitation barium salt produced by the reaction.
Applications:
Industrial applications
It is the main raw material for manufacturing lithopone and zinc salts, also used as mordant dyeing, leather and wood preservative, but also the production of viscose fiber important auxiliary materials and vinylon fibers. Further, in the electrolytic plating industry and also has applications, it can also be used to manufacture cable.
The water industry is the largest amount of cooling water. Cooling water in a closed-cycle cooling system can not have metal corrosion and scaling, so to be treated, a process called water quality stable, zinc sulfate is used here as water quality stabilizer.
