Packaging |
HSC Zinc Sulphate Monohydrate in the woven bag lined with plastic, net wt.25kgs or 1000kgs bags. |
||
Rinsing of zinc containing raw materials → zinc containing raw materials + sulfuric acid → intermediate leaching reaction → coarse filtration → adding double itch water + removing iron → adding zinc containing raw materials, adjusting pH value → pressure filtration → adding zinc powder, removing cadmium → pressure filtration → multi effect evaporation → concentrated crystallization → centrifugal dehydration → drying → packaging.
Ecological use
Zinc can promote the photosynthesis of crops. Zinc is the specific activated ion of carbonic anhydrase in plant chloroplasts. Carbonic anhydrase can catalyze the hydration of carbon dioxide in photosynthesis. Zinc is also an activator of aldolase, which is one of the key enzymes in photosynthesis. Therefore, the use of zinc sulfate monohydrate can enhance the chemosynthesis of plants. At the same time, zinc is an essential component of protein synthesis and ribose in animal and plant cells, which proves that zinc is an essential element for animal and plant growth.
Industrial use
Zinc sulfate monohydrate has been widely used in the fields of chemical industry, national defense, mineral processing, pharmaceutical, rubber, electronics, printing and dyeing agents, bone glue clarifiers and protectants, electroplating, prevention of fruit tree diseases and pests and treatment of circulating cooling water, viscose fiber and nylon fiber. It is the raw material for producing zinc salt and lithophane. It is used for cable zinc and electrolytic pure zinc in the electrolytic industry. It is also used to prevent and cure diseases of fruit tree nursery, wood and leather preservation agent and artificial fiber industry. Mordant in printing and dyeing industry; Preservative for wood and leather; Circulating cooling water treatment agent; Bone glue clarification and preservation agent.
