摘要： PROBLEM TO BE SOLVED: To provide a method for producing a colored slaked lime for a lime plaster containing a coloring substance uniformly dispersed therein and hardly causing an irregular color. SOLUTION: An inorganic material powder as a coloring substance is added to a limestone powder, baked and then slaked to produce a colored slaked lime for a lime plaster. The limestone is preferably a powder having 0.01-0.5mm average particle diameter. An inorganic material such as a pigment or further a sludge prepared by washing the limestone with water is used as the coloring substance. The amount of the coloring substance added thereto is preferably within the range of 1-20wt.% in the limestone. The baking temperature is preferably within the range of 900-1,300 deg.C. Since the sludge when washing the limestone with water contains calcium carbonate at a high concentration, the sludge can directly be used for baking.

摘要： PROBLEM TO BE SOLVED: To obtain a method for producing fine powder of slaked lime capable of eliminating a solvent removing apparatus, simplifying facilities, reducing production processes and lowering a manufacturing cost. SOLUTION: This method for producing fine powder of slaked lime comprises adding 0.01-5wt.% of a hydroxyl group-containing organic compound to quick lime, grinding quick lime to give fine powder of quick lime, or grinding quick lime to give fine powder of quick lime, compounding the fine powder with 0.01-5wt.% of the hydroxyl group-containing organic compound, adding slaking water comprising water or water and the hydroxyl group-containing organic compound to the fine powder of quick lime, staking the fine powder of quick lime to form slaked lime having >=25(m g) specific surface area. A polyhydric alcohol such as ethylene glycol, diethylene glycol, propylene glycol or triethanolamine and a sugar alcohol such as D-glucitol are used as the organic compound. Triethanolamine and D-glucitol are preferable and triethanolamine are most preferable.
