Abstract
Barium fluoride is the important raw and processed materials in chemical industry.The barium fluoride technological process of production is：Technical process is described：To be liquefied 45 DEG C of hot water heatings of HF steel cylinders, and HF gases are passed through in the pure water of equivalent by surge tank（First batch of time, remaining batch is centrate）, fully after dissolving, obtain 50% hydrofluoric acid solution.It is standby that hydrofluoric acid solution pumps into head tank.Barium hydroxide solid and a certain amount of pure water are added in PP reactors（First batch of time, remaining batch is centrate）, be tuned into 50% barium hydroxide suspension, after being sufficiently mixed, be slowly added to hydrofluoric acid solution, when pH value up to it is neutral after, slightly excessive dropwise addition hydrofluoric acid after continuing to stir 20 minutes, stands 3 hours, crystallisation by cooling, is centrifuged, dries to obtain 99.0% barium fluoride finished product.The aqueous solution produced after centrifugation.
Description
1. main raw and auxiliary material
