Green Applications and Technical Expansion of Calcite in the Plastics Industry

The Importance of Calcite

 

Calcite, a calcium carbonate mineral, is widely found in nature and is often used as a raw material for producing ultra-fine ground calcium carbonate. As a calcium carbonate mineral, calcite is extensively applied in industrial production. It serves as an important raw material for manufacturing products such as ground calcium carbonate and calcium oxide, which are widely used in various fields including plastics, rubber, papermaking, and coatings.

 

1.Applications of Calcite

 

Calcite minerals have a wide range of industrial applications. They are important raw materials for producing industrial fillers, pigments, and chemical products like ground calcium carbonate and calcium oxide. These products are further widely used in numerous fields such as plastic products, rubber products, papermaking, toothpaste, coatings, inks, adhesives, food, and medicine.

 

2.Applications of Calcite in the Plastics Industry

 

It is particularly worth mentioning that the use of calcium carbonate as a filler in plastics brings significant benefits. The use of calcium carbonate with a particle size of 1250 mesh or finer in plastics can effectively save petroleum resources, endow films with degradable functionality, and promote the combustion of polyolefins, thereby reducing air pollution. Experiments have proven that using calcium carbonate with a particle size of 1250 mesh or finer as the main raw material can effectively save petroleum resources while endowing films with initial degradable properties. In addition, its filling in films can also promote the rapid and sufficient combustion of polyolefins, reducing the pollution of incineration exhaust gas to the atmosphere.

 

Expansion Brought by Technological Progress

 

With the continuous development of ultra-fine grinding technology, the application fields of calcite powder are also expanding.

 

1.Ultra-fine Grinding Technology

 

With the advancement of ultra-fine grinding technology, the application fields of calcite have been continuously expanded. Its processing process includes steps such as crushing, classification, and surface modification. At present, the processing of calcite mainly includes steps like crushing, classification, and surface modification. For the dry crushing of ground calcium carbonate, it mainly relies on equipment such as Raymond mills or suspension roller mills, ball mills, stirring mills, vibration mills, roller presses, and various types of mechanical impact mills.

 

2.Equipment Support

 

It is worth noting that the GKLMX series ultra-fine vertical grinding mill provides effective support for the ultra-fine crushing of non-metallic mineral materials such as calcite in the production of degradable plastics.
