Several months ago, Rech Chemical Co. Ltd had shared an article about how to produce zinc sulfate heptahydrate with high output and quality. In this summer, continuous severe heat holds the middle-south of China, as Hunan and other places, which has affected zinc sulfate heptahydrate's output.
Why? Zinc sulfate heptahydrate made from zinc sulfate solution by cooling. Only as zinc sulfate solution heated to certain grade and then cooled to below 39 centigrade, zinc sulfate heptahydrate could be gradually precipitated out. Due to zinc sulfate crystallization process needed long time, the factories have to consume more energy to speed the cooling crystallization cans in the continuous hot days. Manufactures aren’t reluctant to afford large amount energy consumption that over the cost, thus they reduce the output even stop the production to control the cost.
In zinc sulfate heptahydrate's tight delivery season, you'd better arrange purchasing plan and scheduling in advance.
