The Use and Precautions of White Cement

Today, I will explain to you the relevant knowledge of what calcium oxide means. Heating calcium oxide in the air and at high temperatures will emit strong white light, called lime light, which is used to manufacture high-strength arc lamps. Calcium oxide is widely used in the construction industry. The slurry made by adding water to a 1:3 (volume ratio) mixture of hydrated lime and sand is called plaster, which is used for bricklaying and other purposes. If you are still confused about what calcium oxide means, why don't you come and learn about it with me!

What does calcium oxide mean

Calcium oxide is a inorganic compound, its chemical formula is CaO, commonly known as quicklime. The physical property is a surface white powder, impure ones are gray white, and when impurities are present, they are light yellow or gray, and have hygroscopicity.

Main uses of calcium oxide

1. Can be used as a filling agent, such as for epoxy adhesives;

2. Used as an analytical reagent, carbon dioxide absorber for gas analysis, spectroscopic analysis reagent, high-purity reagent for epitaxial and diffusion processes in semiconductor production, laboratory ammonia drying, and alcohol dehydration.

3. Used as raw materials, it can be used to manufacture calcium carbide, soda ash, bleaching powder, etc. It is also used for leather making, wastewater purification, calcium hydroxide, and various calcium compounds;

4. Can be used as a flux for building materials, metallurgical flux, cement accelerator, and fluorescent powder;

5. Used as a plant oil decolorizer, drug carrier, soil conditioner, and calcium fertilizer;

6. It can also be used as refractory materials and desiccants;

7. It can be used to prepare agricultural machinery No.1 and No.2 adhesives and underwater epoxy adhesives, and also as a reactant for pre reaction with 2402 resin;

8. Used for acidic wastewater treatment and sludge conditioning;

9. It can also be used as a protective agent for boiler shutdown, utilizing the moisture absorption ability of lime to keep the metal surface of the boiler water vapor system dry and prevent corrosion. It is suitable for long-term shutdown protection of low-pressure, medium pressure, and small capacity drum boilers;

10. It can react with water to prepare calcium hydroxide. The reaction equation is: CaO+H2O==Ca (OH) 2, which belongs to combination reaction.
