Introduction: as we all know, calcium hydroxide has been widely used in our production and life What about the use of calcium hydroxide? Let the small editor of Baibai safety net lead you to learn more about it! Calcium hydroxide is a kind of white powder solid, slightly soluble in water, water solution commonly known as lime water It is commonly known as hydrated lime and hydrated lime What about the use of calcium hydroxide? Baibai safety net and you to understand it! Uses of calcium hydroxide: 1 It can be used as a filler, for example, as an epoxy adhesive; 2 It can be used as an analytical reagent, as a carbon dioxide absorber in gas analysis, as a spectral analytical reagent, and as a high-purity reagent in the epitaxy and diffusion process of semiconductor production, as well as the drying of ammonia gas and alcohol dehydration in the laboratory, etc; 3 It can be used as raw materials to produce calcium carbide, soda ash, bleaching powder, etc., as well as leather making, wastewater purification, calcium hydroxide and various calcium compounds; 4 It can be used as building materials, metallurgical flux, cement accelerator, flux of fluorescent powder; 5 It can be used as decolorizing agent of vegetable oil, drug carrier, soil improver and calcium fertilizer; 6 It can also be used as refractory and desiccant; 7 No.1 and No.2 adhesives for agricultural machinery and underwater epoxy adhesives can be prepared, and they can also be used as reactants for pre reaction with 2402 resin; 8 They can be used for acid wastewater treatment and sludge conditioning; 9 It can also be used as a protective agent for boiler shutdown It can keep the metal surface of boiler water vapor system dry and prevent corrosion by using the moisture absorption capacity of lime It is suitable for the 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: Cao + H Е o = Ca (OH) Е, which belongs to chemical reaction This is the answer about the use of calcium hydroxide provided by Baibai safety net I hope my article will let you have a clearer understanding of this problem!
