Molecular formula: KCL

Relative molecular mass: 74.55

Physical and chemical properties: Potassium chloride is colorless cubic crystals or white crystals. The relative density is 1.984, the melting point is 770℃, and it will sublimate when heated to 1500℃. Easily soluble in water, slightly soluble in glycerin, insoluble in concentrated hydrochloric acid and acetone. It is hygroscopic and prone to caking. Solubility in water increases rapidly with increasing temperature.

Usage

This product is mainly used in the inorganic industry and is the basic raw material for manufacturing various potassium salts or alkali, such as potassium hydroxide, potassium nitrate, potassium nitrate, potassium chlorate, potassium red vitriol, etc. In the pharmaceutical industry, it is used as a diuretic and a drug to prevent and treat potassium deficiency. The dye industry is used to produce G salts, reactive dyes, etc. In agriculture, it is a potassium fertilizer. Potassium chloride tastes similar to sodium chloride (bitter) and is also used as a low-sodium salt or mineral additive. In addition, it is also used to make flame suppressants for muzzles or muzzles, heat treatment agents for steel, and for photography. It can also be used in medicine and food processing. Potassium chloride can also be partially substituted for sodium chloride in table salt to reduce the possibility of high blood pressure.

It is a commonly used inorganic salt shale inhibitor in drilling fluids. It has a strong ability to inhibit the hydration expansion and dispersion of shale and clay. In water-based drilling fluids, it can inhibit the hydration expansion or collapse of well wall mudstone and improve The viscosity and shear force of drilling fluid inhibit salt dissolution in salt rock well sections. If used in conjunction with polymer treatment agents, the effect will be better and can be used to prepare KCL anti-collapse drilling fluid and completion fluid, polysulfonate potassium salt drilling fluid, potassium chloride-silicate drilling fluid, etc. When used to prepare potassium chloride drilling fluid or as an inhibitor, its dosage is generally not less than 7%. This product can also be used as a natural gas hydrate inhibitor in conjunction with organic compounds.
