Calcium carbonate

Calcium powder:Calcium powder can be categorized into: heavy calcium powder, light calcium powder, activated calcium powder, flue gas desulfurization calcium powder, ultrafine calcium carbonate, and others.

Calcium carbonate:The shapes are irregular, with significant differences in particle size. The particles have certain edges and corners, rough surfaces, a wide particle size distribution, and relatively large particle sizes, with an average particle size generally ranging from 1 to 10 μm. Ground calcium carbonate is classified based on its original average particle size (d) into: coarse ground calcium carbonate (>3 μm), fine ground calcium carbonate (1–3 μm), and ultrafine calcium carbonate (0.5–1 μm). The powder characteristics of ground calcium carbonate are: a. irregular particle shapes; b. wide particle size distribution; c. relatively large particle sizes.

Application:In papermaking, plastics, plastic films, chemical fibers, rubber, adhesives, sealants, daily chemicals, cosmetics, building materials, coatings, paints, inks, putty, sealing wax, fillers, felt packaging, pharmaceuticals, food (such as chewing gum, chocolate), and feed, its functions include: increasing product volume, improving processing performance (such as adjusting viscosity, rheological properties, and vulcanization performance), enhancing dimensional stability, reinforcing or semi-reinforcing, improving printing performance, and enhancing physical properties (such as heat resistance, matting effect, flame retardancy, whiteness, and glossiness), among others.

Common specifications for calcium powder include:100 mesh, 200 mesh, 325 mesh, 400 mesh, 600 mesh, 800 mesh, 1250 mesh, 2500 mesh, 400, etc.
