摘要
采用石灰乳一步碳化———添加剂法合成板状碳酸钙 .探讨了添加剂的类型、添加剂量、添加时间及石灰乳的活性等对板状碳酸钙性能的影响 .最佳实验条件 :添加剂为A和B ,石灰乳浓度为3 %～10 % ,反应温度20℃ ,添加剂添加时间为反应5～10min后 ,添加剂用量与石灰乳的比约为1∶600 .该结果对板状碳酸钙生产工艺的设计与改进具有指导意义 .选择不同类型的添加剂、添加剂量、添加时间等 。
The plate shape calcium carbonate was composed by carbonization of the lime and adding some agent The effect of varied agent and quantity and time and the activity of the lime to the quantity of plate shape calcium carbonate was studied The best experimental conditions are:A or B acting as agent;the concentration of lime being 3 %～10 %;reacting temperature being at 20 ℃;the time of adding A or B being at 5～10min after the beginning of carbonization reaction;the ratio of quantity of agent and lime being about 1∶600 The conclusion can be used to the design and development of the technological process of plate shape calcium carbonate By selecting agent and quantity and time, plate shape calcium carbonate with different size can be produced to meet the various needs in chemical industry
