1. Analyzing from the source, the essential differences can be identified.
The differences between these two calcium carbonate "twins" begin with the way they were born:
Heavy calcium carbonate: Obtained by mechanically crushing natural limestone, it retains the original crystalline form of the ore, similar to the coarse flour powder produced by grinding grains with a stone mill;
Lightweight calcium carbonate: Synthesized through chemical precipitation, it resembles laboratory-grown crystals, forming regular spindle-shaped particles;
Density difference: The true density of the former is approximately 2.7 g/cm³, while that of the latter is only 2.5 g/cm³, just like the difference between a solid ball and a hollow ball.
II. The Core Strengths of Super Calcium
As a versatile player in the industrial sector, heavy calcium carbonate exhibits three key characteristics:
Physical stability: Mohs hardness 3, equivalent to the hardness of a copper coin, can enhance the wear resistance of the composite material;
Economy: The filling cost per unit volume is 30% lower than that of light calcium, making it an ideal choice for large-scale applications.
Environmental advantages: The production energy consumption is only 1/5 of that of light calcium, which is more in line with the requirements of sustainable development.
III. The Two Aspects of Application Scenarios
Different characteristics determine the clear division of labor between the two:
Heavy calcium main products: Papermaking filler (accounting for 15% of the cost), PVC pipe reinforcement (addition amount can reach 40%), asphalt pavement modifier;
Light Calcium Special Offer: Pharmaceutical tablet excipients, high-grade paint whitening agents, sealant thixotropic agents;
