It is used to protect fruit trees and seedlings from diseases and pests, or as conservant of wood and leather and in artificial fibre industry. It is also used as nutrition additive in food industry(zinc strengthener).
Application of heptahydrate zinc sulphate:used for man-made fibre solidifying agent; in printing industry for mordant and antalgic; main raw material for inorganic pigments(e.g. lithopone), other zinc salt(e.g. zinc stearate, basic zinc carbonate)and zinc catalyser; conservant for wood and leather, bone glue clarifier; in medical industry for vomitory; prevent diseases and pests to fruit trees and seedlings and make cable and zinc fertilizer; in food industry as nutrition additive(zinc intensifying agent)and so on. |
