The meaning of heavy calcium carbonate: heavy calcium carbonate, also known as ground calcium carbonate (abbreviated as GCC), is produced by directly crushing natural calcite, limestone, chalk, shells, etc. by mechanical methods. Because its sedimentation volume (1.1-1.9mL/g/g) is smaller than that of chemically produced light calcium carbonate (2.4-2.8mL/g), it is called heavy calcium carbonate.
The meaning of activated calcium carbonate: activated calcium carbonate is modified on the basis of ordinary calcium carbonate, so as to achieve the dual purpose of filling and modification in composite products. These modifications include modification of calcium carbonate's crystal morphology, particle size, particle size distribution and surface properties. To improve its comprehensive performance.
The meaning of light calcium carbonate: light calcium carbonate, also known as precipitated calcium carbonate (PCC for short), is made by chemical processing methods. Because its sedimentation volume (2.4-2.8mL/g) is larger than that of heavy calcium carbonate (1.1-1.9mL/g) produced by mechanical methods, it is called light calcium carbonate.
The meaning of nano-calcium carbonate: nano-calcium carbonate is a non-metallic mineral limestone as raw material, an important inorganic salt new product prepared by the precipitation method synthesis nano-powder technology, particle size 10-100nm, because of its small particle size, good activity, is A new type of inorganic material.
