Calcium hydroxide, also known as hydrated lime or slaked lime, is a common inorganic compound widely used in the field of chemical production raw materials. This article will detail the properties and uses of calcium hydroxide.
1. the properties of calcium hydroxide
1. Physical properties
calcium hydroxide is a white powder with high hygroscopicity and can absorb moisture and carbon dioxide in the air. Its solubility decreases with the increase of temperature, but it still has a certain solubility at room temperature.
2. chemical properties
calcium hydroxide is a strong alkali, alkaline, can react with acid to generate salt and water. At the same time, calcium hydroxide can also react with carbon dioxide to form calcium carbonate and water.
2. calcium hydroxide use
1. chemical production
calcium hydroxide in chemical production has a wide range of applications, mainly for the preparation of various calcium compounds and alkaline absorbent. For example, calcium hydroxide can be used as a raw material to produce calcium carbonate, calcium oxide and other compounds, which are widely used in plastics, rubber, coatings and other fields.
2. Environmental protection treatment
Calcium hydroxide has good absorption performance and can be used to treat acid gases in waste gas, such as sulfur dioxide, nitrogen oxides, etc. At the same time, calcium hydroxide can also be used to treat acidic substances and heavy metal ions in wastewater, which has a good purification effect.
3. building materials
calcium hydroxide can be used as building materials, such as the preparation of lime mortar, lime milk and so on. At the same time, calcium hydroxide can also be used in the preparation of building insulation materials, with good thermal insulation performance.
4. Calcium hydroxide
in agricultural fields can be used for soil improvement, adjust soil pH, and improve soil quality. At the same time, calcium hydroxide can also be used to prepare pesticides and fertilizers to improve crop yield and quality.
In conclusion, calcium hydroxide, as a common inorganic compound, has a wide range of uses. Calcium hydroxide will continue to play an important role in the future of raw materials for chemical production.
