Calcium Oxide (CaO), commonly referred to as quick lime , is an extensively utilized chemical compound across various industries. It exists as a white, highly caustic, alkaline, and crystalline solid at room temperature, exhibiting distinct physical characteristics that make it indispensable in numerous applications. The typical appearance of quick lime is a pristine white powder, which, when contaminated with impurities, can turn a light yellow or gray hue. One notable physical property of this compound is its hygroscopicity, meaning it has the ability to absorb moisture from the surrounding environment. This characteristic is particularly significant in industries where moisture control is crucial.
High - purity quicklime (calcium oxide) has several important applications in the field of architectural coatings, which are described as follows
Improving Coating Coverage: Quicklime has a high refractive index and excellent whiteness. It can effectively scatter light, thereby enhancing the hiding power of the coating. This enables the coating to cover the imperfections and color variations of the substrate surface, ensuring a uniform and consistent appearance.
Enhancing Coating Whiteness: The high whiteness of quicklime can significantly improve the whiteness of the coating. For white coatings, it makes them even whiter and more brilliant, while for colored coatings, it can act as a color - adjusting agent and whitener, making the colors more vivid and pure.
Adjusting Coating Texture: When added as a filler, quicklime can modify the texture of the coating. It helps to make the surface of the coating finer and smoother, improving the decorative effect and tactile quality of the coating.
Accelerating Drying: Quicklime reacts with water in the coating to form calcium hydroxide, a process that consumes water. This accelerates the drying rate of the coating, reducing the construction time and increasing work efficiency.
Strengthening Adhesion: The calcium hydroxide produced can react with other components in the coating and substances on the substrate surface, creating chemical bonds or physical adsorption. This significantly enhances the adhesion between the coating and the substrate, ensuring that the coating adheres firmly to the surface and is less likely to peel off.
Increasing Film Hardness: During the film - formation process, the reaction products of quicklime contribute to increasing the hardness and wear - resistance of the coating. This makes the coating more resistant to scratches and abrasion, prolonging its service life.
Modifying Rheological Properties: The appropriate addition of high - purity quicklime can adjust the viscosity and thixotropy of the coating. It gives the coating good fluidity and leveling properties during construction, making it easy to apply evenly by brushing or spraying. At the same time, it can maintain sufficient viscosity when at rest, preventing sagging.
Enhancing Water Resistance: The calcium hydroxide formed by the reaction of quicklime can improve the water resistance of the coating to some extent. It reacts with carbon dioxide in the air to form calcium carbonate, which has better water and chemical resistance. This helps the coating to resist water - related damage such as blistering and peeling in humid environments.
Reducing Costs: As a relatively inexpensive filler, the addition of high - purity quicklime can replace some of the more expensive film - forming materials or pigments without sacrificing the main properties of the coating. This helps to reduce the production cost of the coating, making it more competitive in the market.
