The difference between quicklime and hydrated lime
2021年9月2日 In the lime slurry formed after quicklime slaked, the lime particles form a calcium hydroxide colloidal structure, the particles are extremely fine (particle size is about 1μm), the specific surface area is large (up to 1030m2/g), and a thicker layer is adsorbed on the surface Water film can absorb a large amount of water, so it has a strong ability to retain water, that is, Quicklime reacts with water, generating a great amount of heat We distinguish softburnt lime, mediumburnt lime, and hardburnt lime In the construction industry, quicklime is added to mortar It can also be used as a drying or neutralizing agent, as fertilizer lime and for the production of lime mortar and lime plasterQuicklime preparation Gebr Pfeiffer
