1. Molecular formula: Ca(OH)₂

2. Molecular weight: 74.096

3. Physical and chemical properties:

White powder, odorless and tasteless. This product is a strongly alkaline substance that has irritating and corrosive effects. Inhaling the dust of this product is highly irritating to the respiratory tract and can cause chemical pneumonitis. Eye contact is highly irritating and may cause burns. Accidentally falling into the slaked lime pool can cause corrosion and burns over a large area. Long-term exposure can cause dermatitis and dermatitis ulcers.
 

4. Characteristics and uses:

Calcium hydroxide is widely used in various industries such as environmental protection, chemical industry, medicine, food and agriculture. Calcium hydroxide can neutralize acidic wastewater, capture metal ions, remove fluoride ions, accelerate precipitation, improve sludge dehydration, sterilize and promote hydrolysis of organic matter; in flue gas desulfurization, it is mainly used to neutralize sulfur dioxide, sulfur trioxide and A small part of acidic gases such as fluoride ions and chlorine ions make the sulfur content of the exhaust gas comply with environmental standards; in the chemical industry, it is used as raw material for the production of calcium carbonate, and high-quality products are used in the production of epichlorohydrin and propylene oxide; in medical In the field of dental field, because calcium hydroxide is highly alkaline and can play an anti-inflammatory role, it is widely used in dentistry, which can repair damaged teeth, and can also be used for pulp filling treatment, root canal filling, disinfection, etc.; in the food industry, due to Calcium hydroxide has strong activity and loose structure, and is widely used as a food additive; in agriculture, it is used to reduce the acidity of soil and improve the soil structure.
