China limestone tile-What is limestone?

Today, China limestone tile mainly tell you about what is the relevant knowledge of limestone. Limestone is commonly used in the construction site of the material, with a high-rise buildings after the limestone can be more stable, the industry often use limestone, the use of limestone is very wide. Limestone is a natural formation of the items, it is distributed in many areas of our country, if you want to buy limestone, then directly in the limestone origin of the purchase price will be cheaper. If you are interested in the knowledge of what is the limestone, please let me know about it!

China limestone tile-What is limestone?

Limestone Main Ingredients Calcium carbonate (CaCO3). Lime and limestone are used extensively for building materials, industrial raw materials. Limestone directly processed into stone and fired into lime. Lime absorb moisture or add water to become slaked lime, the main component is Ca (OH) 2, can be called calcium hydroxide, hydrated lime by the deployment of lime slurry, lime paste, used as a coating material and brick adhesive.

Limestone composition

The main component of limestone is calcium carbonate. The limestone can be turned into lime by firing. The chemical composition of lime is calcium oxide, the appearance of block, the color is light gray or light yellow, usually with some impurities. Slaked lime is also the lime, is another kind of limestone, it is formed by the lime tide or water after the formation. The main lime is calcium hydroxide.

In addition, the limestone also has silica, aluminum oxide, calcium oxide, magnesium oxide, magnesium, iron, loss of ignition and other ingredients.

China limestone tile-The use of limestone

Manufacture of glass. Glass production materials are limestone, quartz sand, soda ash, etc., these materials can be obtained after high temperature melting.

Refining steel. In industrial production, limestone or iron melting solvent and runner, where the use of lime, the use of quicklime can be used as slagging materials, filter out sulfur, phosphorus and other harmful work.

Rubber, plastic, paper, cosmetics, toothpaste and other products filler. After firing the limestone, it becomes a pure, dry powdered calcium carbonate, which can be used as a filler for many products.

Manufacture soda ash. Soda is the use of limestone, salt, ammonia and other materials using Solvard method, after a multi-step reaction and obtained by pure lime and chlorine chemical reaction to achieve bleaching.

Making salt. Limestone after chemical processing, can become calcium chloride, calcium nitrate, calcium sulphate and other calcium salts.

Hard water softener. The hydrated lime can be temporarily removed from the hardness of the water, and thus is used as a hard water softener in the industry.

China limestone tile-Desiccant and disinfectant.

Application in Agriculture. First, the lime can be configured as Bordeaux liquid, lime sulfur mixture and other pesticides; Secondly, hydrated lime can change the soil pH, improve the internal composition of the soil, add calcium in the soil; then, lime slurry can be used to paint the trunk, Protect the trees.

Building houses and decorations. Limestone is the main raw material for making cement. In addition, limestone can come to build the external walls of the house and the ground.
