Usage:
Itis mainly used in the inorganic industry and is a basic raw material forproducing various potassium salts or alkalis such as potassium hydroxide,potassium sulfate, potassium nitrate, potassium chlorate, and red strontiumpotassium. The pharmaceutical industry is used as a diuretic and a drug forpreventing and treating potassium deficiency. The dye industry is used toproduce G salts, reactive dyes and the like. In agriculture, it is a potash.Its fertilizer efficiency is fast, it can be directly applied to farmland,which can raise the moisture of the lower layer of soil and have the effect ofdrought resistance. However, it is not suitable for application insaline-alkali land and crops such as tobacco, sweet potato and sugar beet.Potassium chloride is similar in taste to sodium chloride (bitter) and is alsoused as an additive to low sodium or mineral water. In addition, it is alsoused to make muzzle or muzzle flame retardant, steel heat treatment agent, andfor photography. It can also be used in medicine, scientific applications, foodprocessing, and salt can also replace sodium chloride with some potassiumchloride to reduce the possibility of high blood pressure.
