The magic of limestone

For stone people, speaking of limestone is not strange, its main component is calcium carbonate CaCO3, lime and limestone are widely used in building materials and industrial raw materials.Throughout life, in fact, we can see limestone everywhere, perhaps we have long been used to it, but ignored its role, here we revive the brilliance of limestone, let's have a look at the various uses of limestone.

Calcium carbonate can be directly processed into stone and fired into quicklime.The main component of quicklime is CaO, which is generally massive, pure white, and light gray or light yellow when containing impurities.Quicklime absorbs moisture or adds water to become hydrated lime, also known as hydrated lime, its main component is Ca(OH)2.

Generally speaking, limestone is burned to produce purer powdered calcium carbonate, used as filler for rubber, plastic, paper, toothpaste, cosmetics, etc.lime

Alkali lime made with caustic soda and used as an absorbent of carbon dioxide;Quicklime is used as a desiccant and disinfectant.

Not only that, combined with its chemical properties, quicklime also has a use in industry: with quicklime can be prepared lime sulfur mixture, Bordeaux liquid and other agricultural

Medicine;Applying slaked lime in soil can neutralize soil acidity, improve soil structure, supply calcium needed by plants, and promote the growth of crops.

Brush the tree trunk with lime pulp to protect the tree effectively.

In addition, the heavy calcium carbonate made directly from limestone after coarse crushing and crushing can be divided into separate fly powder (95%) because of the different degree of crushing

200 mesh), double fly powder (99% through 325 mesh), triple fly powder (99.9% through 325 mesh), four fly powder (99.95% through 400 mesh, each

Have a purpose.Single fly powder can be used to produce anhydrous calcium chloride, is the auxiliary raw material of sodium dichromate production;Shuangfei powder is the production of anhydrous calcium chloride and glass, etc

White fillers for raw materials, rubber and paints, and building materials;Sanfei powder: used as filler for plastics, paint putty, paint, plywood and paint

Material;It is used as filler for insulating layer of electric wire, rubber molding products and asphalt felt.

As an important component of limestone, calcium carbonate is an important building material.White and pure calcium carbonate rock is called white marble and is often used for decoration

Stone columns or crafts, elegant atmosphere;For impurities have a beautiful pattern of calcium carbonate marble, used to do building wall and wall veneer or shop

Set up the ground;Compact calcium carbonate rock (limestone) can also be directly used for building, but the main use of limestone is to produce cement.

So, in general, limestone is more than a simple stone use, industry, industry and other aspects are indispensable, can not underestimate it!
