The term â€œhydrated limeâ€ is widely used to describe a powdered calcium hydroxide product made by reacting quicklime with a controlled excess of water. The product is essentially dry and generally contains less than 1% of unreacted water. The process is called â€œhydrationâ€ and should be differentiated from â€œslakingâ€ which involves the production of a dispersion of calcium hydroxide in water. However, the expression â€œslaked limeâ€ is used as a generic term for hydrated lime, milk of lime and lime putty. An estimated 10 to 15% of the quicklime produced in developed countries is converted in to hydrated lime and the percentage may be higher in countries which do not have a large steel industry. Hydrated lime is used in mortar, plasters, cements, lime paints, medicine and in agriculture to "sweeten" the acid soil. It is also used in ammonia recovery, in gas manufacture, disinfectant, water softening, purification of juice in cane sugar industry, manufacture of hard rubber products, water paints, petrochemicals, and calcium chemicals like bleaching powder. Hydrated lime is used in curing of leather, in paper and as buffer and neutralizing agent. Hydrated lime is also used as flux in metallurgy, in specialized lubricant, as a bonding agent, as filler, in refractory etc. It is also employed in building construction as cementing material and plasticizer. Hydrated lime is generally supplied to small users in paper sacks or intermediate bulk containers of 0.5 or 1 ton capacity. Where larger amounts are used, the product is delivered in air pressure discharge vehicles (APDVs). Its handling properties, however, do not generally because problems, providing its moisture content are less than 2 % and normal powder handling techniques are used. Hydrated lime absorbs carbon dioxide from the atmosphere, forming calcium carbonate and water. It should, therefore, be stored in dry, draught-free conditions. Due to demand growth, Hydrated Lime is a good project for entrepreneurs to invest.
