轻质碳酸钙是一种用人工方法合成的白色、净纯碳酸钙粉状材料(极细),它是先将石灰石焙烧成生石灰,再用大量的水消解成石灰浆(氢氧化钙),然后送入二氧化碳气,使与石灰浆反应后又回复生成碳酸钙沉淀,再经脱水、烘干而成。用这种方法获得的碳酸钙粉,由于结晶形态不同,所以具有与天然石灰石破碎、磨细后获得的粉料完全不同的性能。它的细度细、纯
Lightweight calcium carbonate is a white, pure calcium carbonate powder material (ultra fine) synthesized by artificial method. It is first calcined into lime, and then digested with a large amount of water into lime slurry (calcium hydroxide). Carbon dioxide gas is then fed to react with the lime slurry to produce calcium carbonate precipitate, which is then dehydrated and dried. The calcium carbonate powder obtained by this method has completely different properties from the powder obtained after crushing and pulverizing the natural limestone due to the different crystal morphology. Its fineness is fine and pure
