When it comes to calcium hydroxide, many people may not know what it is. It should be more familiar with slaked lime and slaked lime, especially in chemical experiments and physical experiments. So, in addition to being able to do experiments, do you know any other uses for this calcium hydroxide?
WHAT IS CALCIUM HYDROXIDE
Calcium hydroxide is a fine white powder produced by a professional calcium hydroxide production line, which is odorless and slightly bitter in taste. It is easy to absorb carbon dioxide and become calcium carbonate when placed in the air. It is made of calcium oxide, that is, quicklime, digested with water, dried, sieved, and air-selected (or crushed by an extension machine).
The chemical formula Ca(OH)2, commonly known as slaked lime and slaked lime, is formed into two layers after adding water. The upper aqueous solution is called clarified lime water, and the lower suspension is called lime milk or lime slurry.
The supernatant clear lime water can test carbon dioxide, and the lower turbid liquid lime milk is a building material. Calcium hydroxide is a binary medium and strong base (calcium hydroxide is considered to be a strong base in the middle school stage, but in fact it cannot be completely ionized in water. It has the property of alkali and has a corrosive effect on skin and fabrics. It has a wide range of applications in industry. It is a commonly used building material, and is also used as a fungicide and chemical raw materials.
Calcium hydroxide is a strong alkaline substance with irritating and corrosive effects. Inhalation of dust is highly irritating to the respiratory tract and may also cause pneumonia. Eye contact is also strongly irritating and can cause burns.
USES OF CALCIUM HYDROXIDE
With the development of modern industry, lime has opened up a variety of uses in many emerging industrial sectors besides the main material of civil engineering. Such as metallurgy, glass, alkali sugar, paper, food, medicine, feed, leather, calcium carbide and organic chemicals, carbonized bricks, carbonized plates and soil improvement, water treatment, gas purification, stone cutting aids, soil stabilizers, A large amount of lime is used in concrete conditioners, chemical reagents, gypsum board caulking coagulants, building adhesive ingredients, calcium alkane sulfonates, pharmaceutical acid stoppers, astringents, hard water softeners, and plastic fibers.
