Modified calcium carbonate

الوصف

Modified calcium carbonate can also be known as Active calcium carbonate, surface treatment of calcium carbonate, colloidal calcium carbonate or Bai Yanhua, referred to as living calcium, is to use the surface modifier on light or heavy calcium carbonate surface modification of calcium in the system.

GCC(Heavy calcium carbonate): short TSP is the use of mechanical grinding of natural calcite directly, limestone, chalk, shells obtained. Calcium carbonate sedimentation volume of 1.**1.4mL / g. 

Character : non-toxic, non irritant odorless, White colour refractive index is slow coloured easily dry, have no water of crystallization, soft, size distribution is wide.

We will provide honest and efficient service to you! 
       Looking forward to cooperating with you.

PCC: precipitated calcium carbonate, also known as, referred to as light calcium, is the burning section of limestone and other raw material of lime and carbon dioxide generated, combined with lime generates digest milk of lime water (calcium hydroxide, the main component), pass into the milk of lime generates carbon dioxide carbonate carbonation Calcium precipitation, dehydration, dry and crush the system. Prepared by drying and grinding. Calcium carbonate sedimentation volume 2.**2.8mL / g.
