摘要： PROBLEM TO BE SOLVED: To provide novel slaked lime with a large specific surface area, which shows an excellent performance at transport, is suitable for removing acidic substances from combustion exhaust gas of wastes etc., has characteristics inherent in calcium hydroxide with a large specific surface area, such as high reactivity with acid gas and reduced generation of fly ash or dust and avoids troubles concerning discharge from storage tanks and occlusion of piping. SOLUTION: The slaked lime with a large specific surface area essentially comprises calcium hydroxide and has a nitrogen adsorption specific surface area of ≥35 m 2 /g and an average particle size of ≥75 μm for particles within the range of 40-200 μm and contains ≥45 wt.% particles within the range of 40-200 μm. The coarse particles of the slaked lime have small contact area with other particles when they contact or collide with other particles in the piping etc., which results in little coagulation or growth, and their large mass and inertia force prevent their deposition on interior of the piping etc. Therefore, the obtained slaked lime with a large specific surface area shows an excellent performance at transport.

摘要翻译：要解决的问题：提供具有大比表面积的新型熟石灰，其在运输中表现出优异的性能，适用于从废物等的燃烧废气中除去酸性物质，具有氢氧化钙固有的特性大的比表面积，例如与酸性气体的高反应性，并减少飞灰或灰尘的产生，并避免从储罐排放和堵塞管道的麻烦。解决方案：具有大比表面积的熟石灰基本上包含氢氧化钙，氮吸附比表面积≥35m2 / SP / g，平均粒度≥75μm，颗粒在40-200μm范围内，并且在40-200μm范围内含有≥45wt。％的颗粒。消石灰的粗颗粒当与管道等中的其它颗粒接触或碰撞时具有与其他颗粒的接触面积小，这导致凝固或生长很少，并且它们的大质量和惯性力防止其沉积在管道等。因此，具有大比表面积的获得的熟石灰在运输时表现出优异的性能。版权所有（C）2005，JPO＆NCIPI

摘要： PROBLEM TO BE SOLVED: To obtain a surface-treating agent that attaches homogeneously to a surface of magnesium hydroxide grain and gives as a result a flame retardant composition, and, when it is e.g. kneaded with a synthetic resin and when the kneaded material is used for producing a product, imparts the product with a flame resistance with a sufficient water resistance without spoiling an intrinsic specific character of the synthetic resin, to provide a method for preparing the flame retardant composition using the surface-treating agent, and to obtain a flame retardant composition obtainable by the method.
SOLUTION: The surface-treating agent for preparing the flame retardant composition having nuclei of magnesium hydroxide grains comprises a specified dicarboxylic acid monoester.
