China Limestone factory-Which industries use limestone

Power plant desulfurization, paper industry, cement plants, steel plants, power stations and so on to use limestone.

The highest requirements for lime purity are pharmaceuticals, food additives, sugar, chemicals, pesticides and other industries; the lime activity is the highest demand for metallurgy, smelting industry; the highest requirements for lime whiteness paint, paper and other industries.

Use lime, limestone, lime and dolomite can do

1. Power station: lime, which is the cheapest base, is widely used to remove acid gas from power stations.

2. Waste Incinerator: Similarly, when the waste is burned to produce energy, lime can be used to remove the acid flue in this process, the energy of the released gas.

3. Concrete dam lime and concrete or "limecrete" controlled by sand, aggregate, binder and water. Portland cement is usually used as a binder, although it can also be used for hydraulic lime or slaked lime.

4. Sewage Treatment: Lime products are widely used to treat waste and waste water to neutralize acids and reduce nutrients such as phosphorus and nitrogen.

5. Beet / sugar processing: to precipitate impurities from sugar beet and sugar cane extract, sugar maker using lime. Lime can also be used to neutralize and produce the scent of beet washed and transported.

6. Fish farming: Farmers use slaked lime to control pH, improve acidic ponds and lakes, in order to make the environment more suitable for aquatic organisms, especially fish. Therefore, lime is used to fish farmers farming habitat, keeping a suitable one.

7. Drinking water works: hydrated lime and / or lime milk for disinfecting water by adjusting its pH and removing hardness to suit human consumption.

8. Sewage works: lime can also be added to the sewage to adjust the pH, remove the metal and nutrients, and disinfect the sludge so that it can be used, can also be used for agriculture, or as a landfill.

9. Protection / Legacy: Building lime mortar built before 1900. So when they are damaged and need to be repaired, it is necessary to do so when using the same material (hydraulic lime mortar, plaster, and present). Modern materials are very different, thus causing considerable damage to heritage buildings.

10. Lime Mortar: Lime Pulp is a traditional way to draw a color foundation that makes the puff wall.

11. Aluminum: lime as a flux for smelting copper, lead, zinc and other metal ores.

12. Plastic: lime with any free water to form hydrated lime. When removing water from the system and handling it, you can use products that are heated in the manufacturing process, such as plastic.

13. Iron and steel manufacturing: mainly with lime and dolomite lime as flux impurity alkaline oxygen steelmaking (BOS) process. In addition, lime is also used in desulphurization pig iron, which is very important in the process of arc steelmaking.

14. From the cliff: old lime quarry to restore the use of inert waste, which tends to maintain a high level before the quarry of the creatures

Diversity than wildlife sanctuary. Now, many of the restoration quarries of the "National Nature Reserve", "Wildlife Conservation

District "," with special scientific value place ".

15. Asphalt: Slaked lime is often used as an additive to "heat mix asphalt" to increase its overall resistance, strength and stiffness. These properties are of particular importance, as the asphalt used for surface busy roads.

16. Soil stability: lime can be used to stabilize waterlogging, mud or contaminated land. When the land is improved, the lime is dry out

To the water bearing material. This process is often infeasible for converting sites into a solid work platform for development.

17. Pharmaceuticals: Lime can be used to make many inorganic salts, such as calcium phosphate. Then, this chemical substance is often used as

A toothpaste additive.

18. Engine oil additives: Some oil additives (including motor vehicles) react, hydrated lime alkyl phenols or

Sulfonic acid.

19. Building structure: Overall, lime plays an important role in construction. For example, they are used in the soil to dry, improve and stabilize. As a component, mortar, external rendering and internal plaster. As an anti-stripping agent asphalt production and apron road construction. As a production of adhesive, fire board and concrete brick, aircrete.

20. Aerated concrete blocks: lime, cement, sand, water and aluminum powder mixed to the slurry rise, the formation of honeycomb structured

Of the block (filling), it has excellent insulation, sound insulation performance.

twenty one. Gypsum: lime by adding gypsum to improve operability, improve cohesion, control the coagulation time, improve water retention capacity,

Increase alkalinity. These features make lime mortar extremely durable and reliable.

twenty two. Mortar: the same plaster, lime can also be added to the mortar mixture for the final product of the soft and hard characteristics, with the promise

Many benefits. These benefits include higher workability and water retention, increased sexuality and adhesion, but the most important is the "self

Healing "ability!

twenty three. Chicken feed: Sugar plant waste lime can be used to produce one of the ingredients needed for the production of essential chicken feed additives. Make up

Filling the chicks to improve and enhance the strength of their eggshells. In general, supplements are simple, effective and cheap

of.

twenty four. Fruit planting: such as apples and other fruits mature, they release carbon dioxide. At the time of storage, the oxygen in the atmosphere

And the reduction of carbon dioxide levels accelerates the deterioration of fruit. Fruit around the air to circulate, as well as the global slaked lime, carbon dioxide

The level of reduction and fruit keep fresh for longer.

25. Soil treatment: can use calcium carbonate, lime, slaked lime to adjust the pH value, get the best growth conditions, so as to improve the crop yield of the soil.

26. Paper manufacturers: Lime can be used to make fillers and coated products for the paper industry. The process of making lime paper and pulp is used during the drying process.

27. Glass manufacturers: dolomite and high calcium lime in fine crushed form can be used in the manufacture of glass. The lime used in this process also reduces the need for expensive bleach additives.
