CaCo3 Calcium Carbonate
Light calcium carbonate calcium carbonate precipitated calcium carbonate, referred to as PCC.
Light calcium carbonate was prepared by chemical processing. As the settling volume (2.4-2.8mL/g) is larger than that of the heavy calcium carbonate (1.1-1.9mL/g) produced by mechanical method, it is known as light calcium carbonate.

1, in the rubber and building materials in the application of calcium, tungsten in the rubber products is a large amount of filler, saving expensive natural rubber and reduce costs, but also can improve the rubber processing performance, tear resistance, compression deformation and Resistant to bending performance, ultra-fine calcium to join the building materials can improve heat resistance, chemical resistance, cold, sound insulation, shock and easy processing performance, thereby greatly improving product performance and quality to reduce production costs.
2, in the plastic and paper industry applications, tungsten in the plastic products to increase connectivity, improve heat resistance, improve the processing performance of plastics, improve heat resistance, improve the processing performance of plastics, scratch resistance, smoothness and On the gap impact strength and other aspects have a significant effect, tantalum for paper can reduce the machine's wear and tear, improve the paper whiteness, strength, opacity and smoothness, giving the paper a good degree of flexibility and flexibility , To enhance the absorption of ink and water.
3, in the coating and beverage industry applications, the more fine calcium added to the paint can be used as whitening quality filler, improve the paint, paint the gloss, and play a reinforcing effect,
4, is the production of gusset and plastic must add material.
Applications:
