| titleOfInvention | The manufacture method of white lime particle, light calcium carbonate, the paper using it and White Board and light calcium carbonate |
| abstract | A kind of white lime particle, in its volume particle size distribution, particle diameter is that the cumulative volume of the particle of less than 1.0 μm is less than 20% and the cumulative volume that particle diameter is the particle of less than 100 μm is more than 95%.In the operation obtaining this white lime particle, preferably to be less than 2.5 with the mol ratio of unslaked lime, scope is added digestion water and mixes in unslaked lime.By this white lime particle slurry, this white lime slurry of 20 ~ 70 DEG C is become light calcium carbonate by being blown into carbonated gas by carbonating.The light calcium carbonate obtained can be used as the filler of paper or the pigment of White Board. |
