What's the Difference between the (Nano) Precipitated Calcium Carbonate (10-100nm or) and Normal Ground Calcium Carbonate

 
What's the Difference between the
(Nano) Precipitated Calcium Carbonate (10-100nm or) and Normal Ground Calcium Carbonate
  
Generally speaking
1) Tap density difference:
2)Particle size difference:
Ground Calcium Carbonate particle size is bigger than Precipitated Calcium Carbonate.
3)Shapes difference:
Ground Calcium Carbonate shape is irregular,
Precipitated Calcium Carbonate is Spindle shape.
Nano Precipitated Calcium Carbonate is Cubic shape.

The Precipitated Calcium Carbonate has following advantages than Ground Calcium Carbonate:
1) Dispersed very even in the finished products;
2) With Well distributed color;
3) Better tensile strengthen;
4) Longer life
5) Stronger wear-ability;
6) More fatigue resistance.
7) With smaller friction factor in producing procedure, can get stronger granulating ability;
8)Finished products can get smoother surface and good forming ability.
9)(Nano) Precipitated Calcium Carbonate can increase the product volume with lighter weight.
