Product Description
Product Description

 

Chemical formula: CA(OH)2
English name: Calcium hydroxide
Molecular weight: 74.09

Physical and chemical properties
1. Appearance: White powdery solid, delicate, odorless.
2. Solubility: Slightly soluble in water, its aqueous solution is commonly known as lime water, and its solubility decreases with increasing temperature. At 20 ºC, approximately 0.165 grams of hydrated lime can be dissolved in 100 grams of water. As the temperature increases to 100 ºC, the solubility decreases to around 0.077 grams.
3. Density: Approximately 2.211g/cm ³
4. Alkaline: It is a strong alkaline substance with alkaline properties. 
5. Stability: It is easy to absorb carbon dioxide in the air and turn into calcium carbonate. Prolonged storage will react with carbon dioxide in the air, reducing the purity and quality of hydrated lime. Under high temperature conditions, hydrated lime will decompose into calcium oxide and water, with a decomposition temperature generally around 580 ºC.

Application

 


1. Construction industry: It is an important building material that can be used for masonry, plastering, painting, etc. Mortar made by mixing with sand, cement, etc. has good adhesion and strength, which can make buildings more sturdy. It can also be used to make lime soil, ternary soil, etc., for laying road base, improving the bearing capacity and stability of the road.
2. Environmental protection field: commonly used for the treatment of acidic wastewater and waste gas. In wastewater treatment, hydrated lime can neutralize the acid in the wastewater, adjust the pH value of the wastewater, and precipitate heavy metal ions, thereby achieving the goal of purifying the wastewater. In exhaust gas treatment, it can be used to absorb acidic gases such as reduce air pollution.
3. In the agricultural field, it can be used to improve acidic soil, neutralize acidic substances in the soil, adjust the pH value of the soil, and make the soil more suitable for crop growth. It can also be mixed with copper sulfate to prepare Bordeaux mixture for the prevention and control of plant diseases and pests, such as grape downy mildew and apple anthracnose.
4. Chemical industry: It is an important raw material for the production of chemical products such as calcium carbonate, calcium chloride, magnesium hydroxide, etc. In the paper industry, the sizing and bleaching processes used for paper can improve its water resistance and whiteness. In the rubber industry, as fillers and activators, it can improve the performance and quality of rubber.
