Modified limestone powder as well as preparation method and application thereof
The invention discloses modified limestone powder as well as a preparation method and application thereof, and belongs to the technical field of building materials. The invention provides a preparation method of modified limestone powder. The preparation method comprises the following steps: mixing and grinding a limestone raw material and a grinding aid; the grinding aid comprises sodium pyrophosphate, sodium gluconate, sodium citrate, an alcohol amine compound and water. According to the preparation method, the particle size of the obtained modified limestone powder can be effectively reduced, the sphericity of the modified limestone powder is improved, and meanwhile the content of free calcium ions in the modified limestone powder is reduced. The invention also provides the modified limestone powder prepared by the preparation method and application of the modified limestone powder.
本发明公开了一种改性石灰石粉及其制备方法和应用，属于建筑材料技术领域。本发明提供了一种改性石灰石粉的制备方法，所述制备方法包括将石灰石原料和助磨剂混合研磨；所述助磨剂包括焦磷酸钠、葡萄糖酸钠、柠檬酸钠、醇胺化合物和水。所述制备方法，能够有效降低所得改性石灰石粉的粒径、提升其球形度，并同时降低其中游离钙离子的含量。本发明还提供了上述制备方法制得的改性石灰石粉，及所得改性石灰石粉的应用。
