Release time:
2024-09-10
Common specifications for heavy calcium carbonate powder include 100 mesh, 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1,250 mesh, 2,500 mesh, and 4,000 mesh. Different mesh sizes are suited to various application areas and process requirements.
Heavy calcium carbonate powder, commonly referred to as heavy calcium, is a powdered inorganic filler produced by grinding natural carbonate minerals such as calcite, marble, and limestone. It boasts high chemical purity, strong inertness, resistance to chemical reactions, excellent thermal stability, high whiteness, low oil absorption, low refractive index, soft texture, dryness, absence of water of crystallization, low hardness and abrasion value, non-toxicity, tastelessness, odorlessness, and good dispersibility. The following are the main application areas of heavy calcium carbonate powder:
-
Construction industry In the construction industry, heavy calcium carbonate powder is extensively used in wall materials, roof insulation layers, dry-mix mortars, and concrete. It not only helps reduce production costs but also enhances the toughness and strength of products, thereby improving the overall performance of construction materials.
-
Chemical industry In the chemical industry, heavy calcium carbonate powder is used as an abrasive in toothpaste and as a filler in plastics and rubber. In plastic products, it serves as a reinforcing skeleton, enhancing dimensional stability, hardness, and surface gloss. In the rubber industry, it is one of the most widely used fillers, increasing product volume, reducing the consumption of natural rubber, lowering costs, and improving tensile strength, tear strength, and abrasion resistance.
-
Paper-making industry In the paper-making industry, heavy calcium carbonate powder is used as a sizing agent to enhance paper brightness and strength while reducing production costs.
-
Coatings Industry In the coatings industry, particularly in waterborne coatings, heavy-grade calcium carbonate powder is widely used. It helps prevent sedimentation, enhances dispersibility and gloss, and improves the overall performance of the coating. Its typical dosage in waterborne coatings ranges from 20% to 60%.
-
Other industries In addition, heavy calcium carbonate powder is used in a variety of fields, including inks, paints, pharmaceuticals, food products (such as chewing gum and chocolate), animal feed, and soil conditioners. In the pharmaceutical industry, it is employed in the production of antipyretic and analgesic drugs as well as in the manufacture of artificial teeth; in cosmetics, it helps to enhance the sensory experience during use.
Common specifications for heavy calcium carbonate powder include 100 mesh, 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1,250 mesh, 2,500 mesh, and 4,000 mesh. Different mesh sizes are suited to various application fields and process requirements.
In summary, heavy calcium carbonate powder plays a vital role in industrial production due to its excellent properties and wide range of applications.
