What can be made from lime? Discover the versatile uses of lime
Lime, as a common building material, actually has a wide range of uses in daily life. From construction to agriculture, from industry to environmental protection, lime has a wide range of applications. This article will introduce you to the various uses of lime in detail, and provide hot topics and hot content in the past 10 days to help you better understand the practical value of lime.
Basic introduction to lime
Lime (chemical name is calcium oxide, CaO) is a white solid produced by calcining limestone at high temperatures. Depending on its use and processing methods, lime can be divided into various forms such as quicklime, hydrated lime and lime paste. The following are the main classifications of lime:
| Type | chemical formula | Main purpose |
|---|---|---|
| quicklime | CaO | Building materials, industrial raw materials |
| slaked lime | Ca(OH)₂ | Agriculture, environmental protection, coatings |
| lime plaster | Ca(OH)₂(water) | Building plastering and decoration |
Lime’s wide range of applications
1.building materials: Lime is an indispensable material in traditional construction and is commonly used in making mortar, plastering and masonry. Lime mortar has good adhesion and air permeability, and can effectively prevent wall cracking.
2.agricultural use: Hydrated lime (calcium hydroxide) is often used in soil improvement, which can neutralize acidic soil and increase crop yields. In addition, lime is also used for disinfection and insecticide to reduce the occurrence of pests and diseases.
3.Industrial raw materials: Lime is an important raw material for many industrial processes, such as paper making, sugar refining, metallurgy, etc. In the paper industry, lime is used to bleach and purify pulp; in the metallurgical industry, lime is used to remove impurities from ores.
4.Environmentally friendly applications: Lime plays an important role in sewage treatment and waste gas treatment. It can neutralize acidic wastewater and remove heavy metal ions. It can also be used for flue gas desulfurization to reduce air pollution.
