What Is Limestone? What Are The Uses Of Limestone?

Limestone is a naturally formed object, it is distributed in many areas of our country, limestone is commonly used in construction sites, limestone is very widely used. Today's mini-editor explains in detail what limestone is and what it is used for.

What is limestone?

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are used extensively in building materials and industrial raw materials. Limestone is processed directly into stone and burned into raw lime. Raw lime moisture absorption or water to become cooked lime, the main ingredient is Ca (OH)2, can be called calcium hydroxide, cooked lime is formulated into lime paste, lime paste, etc., used as coating materials and brick adhesive.

The use of limestone

1, the manufacture of glass. Glass is made of limestone, quartz sand, soda, etc. , which can be obtained after high temperature smelting.

2, steelmaking. In industrial production, limestone is also iron-making solvent and invender stone, here is the use of raw lime, the use of raw lime can be used as a slag material, filtering out sulfur, phosphorus and other harmful work.

3, rubber, plastic, paper, cosmetics, toothpaste and other products fillers. Limestone is burned and turned into pure, dry, powdered calcium carbonate, which can be used as a filler for many products.

4, the manufacture of pure alkali. Pure alkali is the use of limestone, salt, ammonia and other materials using solva, after a multi-step reaction to obtain, through the pure removal of lime and chlorine gas chemical reaction to achieve bleaching.

5, make salt. Limestone can be turned into calcium chloride, calcium nitrate, calcium sulphate and other calcium salts after chemical processing.

6, hard water softener. Cooked lime can temporarily remove the hardness of water and is therefore used as a hard water softener in industry.

7, desiccant and disinfectant.

8, the application of agriculture. First of all, raw lime can be configured as Bordeaux liquid, lime sulfur compound and other pesticides; Secondly, ripe lime can change the acidity and alkalinity of soil, improve the internal composition of soil, supplement the calcium in soil; Lime pulp can then be used to paint the trunks to protect the trees.

9, the construction of houses and decoration. Limestone is the main raw material for cement. In addition, limestone can be used to build the exterior walls and floors of houses.
