In the construction industry\u003cbr\u003eThis is one of the raw materials in the construction industry. Lime is mixed with cement and water in specific proportions to create mortar for building and plastering. Mortar containing lime has high adhesion when dried due to the loss of water, which causes calcium hydroxide to crystallize; simultaneously, carbon dioxide in the air also causes a carbonation process, creating a mixture with high hardness.\u003cbr\u003e2. In manufacturing industry\u003cbr\u003eApplied in the production of silicate bricks and glass.\u003cbr\u003eUsed quicklime to remove impurities in the production of metals and alloys such as steel, magnesium, aluminum, etc.\u003cbr\u003eActs as a raw material in the production of calcium carbide, soda ash, and bleaching powder.\u003cbr\u003eIn the hygiene industry: an effective anti-freezing component.\u003cbr\u003eUsed to purify citric acid, glucose, and dyes.\u003cbr\u003e3. In ceramic production\u003cbr\u003eUsed as a fluxing agent for medium and high-fire glazes at temperatures of 1100°C, helping the resulting product achieve higher hardness, better scratch resistance, glaze color retention, and acid resistance.\u003cbr\u003eHelps reduce viscosity in glazes with high silica content.\u003cbr\u003e4. In wastewater treatment\u003cbr\u003eQuicklime is used in water and wastewater treatment to reduce acidity or help remove impurities such as phosphate and others.\u003cbr\u003eApplied in pollution control: used in scrubbers to remove sulfur-based exhaust gases and treat certain liquids.\u003cbr\u003e5. In laboratory settings\u003cbr\u003eQuicklime is used as an analytical reagent, CO2 absorbent, spectral analytical reagent, and high-purity reagent for epitaxial and diffusion processes in semiconductor manufacturing, as well as for drying ammonia and dehydration in the laboratory.\u003cbr\u003e6. Other applications\u003cbr\u003eLimewater can be used to soak ingredients such as winter melon, carrots, coconut, etc., in jam processing.\u003cbr\u003eIn aquaculture: acts to neutralize acidity (alum), disinfect, kill fungi, detoxify the environment, reduce pH levels, and improve soil.\u003cbr\u003eDue to its strong hygroscopic properties, calcium oxide is also used to dry many substances.\u003cbr\u003eNotes on storage and use of quicklime\u003cbr\u003eTo prevent lime from reacting with water vapor in the air, which reduces its quality, lump lime should not be stored for long. It should be slaked as soon as possible or ground into a fine powder and stored in sealed bags.\u003cbr\u003eSlaked lime should be submerged in pits with a layer of sand or water 10 to 20 cm thick on top to limit the contact between the lime and carbon dioxide in the air.\u003cbr\u003eLime that has turned into calcium carbonate (stony lime) will have reduced quality and plasticity, thereby decreasing its adhesive ability, so proper storage is required.\u003cbr\u003eDistinguishing between quicklime, slaked lime, and limestone\u003cbr\u003eAs we have partially understood what quicklime is above, what are slaked lime and limestone, and how do they differ from quicklime?\u003c\/p\u003e\n\u003cp\u003eQuicklime is a chemical compound with the formula CaO and is a white solid. When it reacts with water, it produces Ca(OH)2.\u003cbr\u003eSlaked lime, or Calcium hydroxide, is a chemical compound with the formula Ca(OH)2. It is a colorless crystalline substance or a white powder. It is the product obtained when calcium oxide reacts with water. Slaked lime is widely applied in various fields of industry such as water treatment, cleaning, construction, fertilizer production, etc.\u003cbr\u003eLimestone is a type of sedimentary rock composed chemically of calcite and aragonite minerals with the chemical formula CaCO3. Limestone is rarely found in pure form and is often mixed with impurities such as shale, silica, igneous rock, clay, mud, etc. It comes in various colors, ranging from white to ash, pale green, yellow, dark pink, or even black.\u003c\/p\u003e","brand":"特种化工电气解决方案服务商","offers":[{"title":"Default Title","offer_id":67594380116056,"sku":null,"price":0.0,"currency_code":"VND","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0604\/3051\/6312\/files\/voi-cao-bot-5267.jpg?v=1790828253","url":"https:\/\/duoduo1234.com\/en\/products\/canxi-oxit","provider":"特种化工电气解决方案服务商","version":"1.0","type":"link"}
