The chemical formula of quicklime is CaO, which is often found on our construction sites, also known as calcium oxide, which is a natural rock whose main component is calcium carbonate, calcined under appropriate circumstances, and the calcium oxide left after removing carbon dioxide gas, the average person uses him as a desiccant. This is a white object with an unfixed shape.
Quicklime can become hydrated lime after moisture absorption or adding water, so that it can be blended into lime slurry, lime paste and lime mortar as coating materials, in addition to as building materials, can also be used to make rubber, plastic, paper, toothpaste and cosmetics filling materials, while quicklime can also be used as desiccant and disinfectant, this use is widely used in ordinary life. In agriculture, quicklime can also be turned into fertilizer, and the quicklime can improve the structure of the soil and supplement calcin for plants.
Hot lime is a white powdery solid. Chemical formula Ca(OH)2, also known as calcium hydroxide, slaked lime, after adding water, there are two layers, the upper aqueous solution is called clear lime water, and the lower layer of suspension is called lime milk or lime slurry. The upper layer of liquid clarified lime water can test carbon dioxide, and the lower layer of turbid liquid lime milk is a building material. Calcium hydroxide is a white powdery solid that dissolves in water. Calcium hydroxide is a strong alkali, with alkali generality, is a strong alkali, corrosive to the skin, fabric. Calcium hydroxide has a wide range of applications in industry. White powder, produced by the reaction of quicklime and water, its saturated aqueous solution is called lime water. It is a commonly used building material, and is also used as a fungicide and chemical raw materials.
The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are raw materials used in a large number of building materials and industries. Limestone can be processed directly into stone and fired into quicklime. Quicklime CaO absorbs moisture or adds water to become hydrated lime, the main component of hydrated lime is Ca (OH) 2, can be called calcium hydroxide, hydrated lime is blended into lime slurry, lime plaster, etc., used as coating materials and brick binders.
