Applications and Quality Requirements of Calcium Carbonate in the Food Industry

Calcium carbonate is an inorganic compound with a wide range of sources and abundant resources. It is a common substance on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine, and is also a major component of animal bones and shells. It is widely used in various fields, including industry, food additives, medicine, feed additives, building materials, rubber, plastics, papermaking, inks, daily cosmetics, coatings, glass, asphalt, insulation materials, adhesives, sealants, military and defense.

Calcium carbonate, other names

Calcium carbonate is widely used as a filler in resins such as polyvinyl chloride (PVC), polyethylene (PE), polypropylene (PP), and acrylonitrile butadiene styrene (ABS). The addition of calcium carbonate plays a role in improving certain properties of plastic products and expanding their application range. In plastic processing, it can reduce resin shrinkage, improve rheology, and control viscosity.

Calcium carbonate fineness D97 reference table

Calcium carbonate fineness D97 reference table. Calcium carbonate is a common inorganic compound widely used in various fields. The fineness of calcium carbonate refers to the size and distribution of its particles, usually represented by the D97 value. The D97 value is the cumulative percentage of particles with a particle size less than or equal to this value in the particle size distribution curve.

Development of the Calcium Carbonate Industry

Development of the calcium carbonate industry. The calcium carbonate industry is a traditional industry in China. Because calcium carbonate is not difficult to find in nature, and the long-term market demand in the past was mainly for low-value white powder materials, the product upgrading of the domestic calcium carbonate industry has been slow, and it has mainly produced low-end products for a long time. With the country's vigorous promotion of industrial structure adjustment and energy conservation and emission reduction, the ultra-fine calcium carbonate industry in Guangdong, China, has undergone large-scale transformation and upgrading.

How is calcium carbonate processed into ultrafine calcium carbonate powder?

How is calcium carbonate processed into ultrafine calcium carbonate powder? The process of processing calcium carbonate into ultrafine calcium carbonate powder: 1. For the ultrafine processing of calcium carbonate, a fully automatic computer-controlled process can be used to perform grinding and the first classification.
