Product Description

CHARACTER

potassium chloride (KCl), chemical formula for KCl, is a colorless or white crystal, salty, 1.987 relative density, melting point 773 ℃, soluble in water. It is an important inorganic salt compound, which is widely used in agriculture, industry and medicine. In agriculture, potassium chloride, as a potassium fertilizer, can effectively supplement the potassium element in the soil and improve the yield and quality of crops; in industry, potassium chloride is used to make various potassium salts, such as potassium carbonate, potassium hydroxide, etc. These potassium salts are important raw materials for glass, papermaking, printing and dyeing, medicine and other industries; in addition, potassium chloride is also used in the field of medicine as a drug for the treatment of hypokalemia. As a multifunctional chemical, potassium chloride has a wide range of applications in the national economy.

APPLICATIONS

(1) Potassium chloride is widely used in the field of medicine as an electrolyte balance regulator for the treatment and prevention of hypokalemia, such as hypokalemia caused by insufficient eating, vomiting, severe diarrhea, and arrhythmia caused by digitalis poisoning.

(2) In the inorganic industry, potassium chloride is the basic raw material for the manufacture of various potassium salts such as potassium hydroxide, potassium sulfate, potassium nitrate, etc. These potassium salts are widely used in glass manufacturing, ceramic production, detergent formulations, fertilizer production, and explosives Manufacturing and other industrial sectors.

(3) Potassium chloride is an important potassium fertilizer in agriculture, which has the characteristics of fast fertilizer efficiency and can be quickly absorbed and utilized by crops. It is directly applied to farmland, can promote crop growth, improve yield and quality, while the soil moisture rise, with drought resistance.

(4) potassium chloride is also used in the manufacture of muzzle or muzzle flame arrestor, as well as steel heat treatment agent, in the steel smelting and processing process plays a key role.

(5) In the food industry, potassium chloride is often used as a low-sodium salt additive because of its taste similar to sodium chloride and high potassium content to reduce the sodium content in table salt and help prevent and control hypertension. And other cardiovascular diseases. At the same time, it is also used to make athlete drinks, etc., to supplement the potassium required by the human body.
