Ground calcium carbonate GCC: It is a powder product obtained by mechanical grinding of natural ore. The bulk density is generally 0.8-1.3g/cm3, and the whiteness is 89%-93%. According to the average particle size can be divided into:
Coarse ground calcium carbonate >3μm
Finely ground calcium carbonate 1-3μm
Ultrafine calcium carbonate 0.5-1μm
Light calcium carbonate LCC: It is a precipitated calcium carbonate powder product obtained by chemical reaction. The bulk density is generally 0.5-0.7g/cm3, and the whiteness is 92%-95%. According to the average particle size, it can be divided into:
Particulate Calcium Carbonate >5μm
Micronized calcium carbonate 1-5μm
Fine calcium carbonate 0.1-1μm
Ultrafine calcium carbonate 20-100nm
Ultrafine calcium carbonate <20nm
Nano-calcium carbonate: ultra-fine light calcium carbonate and ultra-fine light calcium carbonate are collectively called nano-calcium carbonate (1-100nm).
Activated calcium carbonate: The surface of calcium carbonate is modified to obtain active calcium carbonate. The most significant difference from inactive calcium is its hydrophobicity.
Calcium carbonate is an important industrial raw material, which is widely used in plastics, papermaking, rubber, construction, food, medicine and other fields. So, what types of calcium carbonate are needed in different industries?
1. PVC wallpaper: 1250 mesh active heavy calcium
2. Silicone glue: superfine heavy calcium (about 2800 mesh)
3. Steelmaking: very thick stones (5-10mm)
4. ABS material: filling masterbatch (above 600 mesh, 400 mesh at the low end is also acceptable, depending on whether the raw material is waste or other), light calcium, heavy calcium, nano calcium can also be added
5. PP: filler masterbatch
6. Calendering film: (powder) 2500 mesh heavy calcium/1250 mesh light calcium, the production line is filled with relatively thick 325-800 mesh (granule) 400-800 mesh masterbatch
7. PVC edge: 1250 mesh heavy calcium
8. PVC leather: heavy calcium
9. PU leather: light calcium
10. Plastic bucket: PE filled masterbatch

21. Artificial marble: 80-90 mesh
22. Paint and white paint: light calcium/heavy calcium above 1000 mesh, light calcium above 2500 mesh has better water absorption and faster drying, and nano calcium for paint
23. Compound fertilizer: light calcium/heavy calcium (can be added together)
24. Soil pH adjustment: calcium carbonate (increases alkalinity), quicklime (increases acidity)
25. Resin: 2500 mesh light calcium, 1250 mesh active light calcium, adhesive nano calcium
26. PVC pipe: 1250 mesh light calcium/heavy calcium
27. PVC board: 1250 mesh active light calcium, better 2200 mesh, activation degree is about 80

31. Papermaking: 400-1500 mesh light calcium/heavy calcium
32. Glass, photovoltaic glass: 200 mesh heavy calcium
33. Emulsion paint: heavy calcium/light calcium, few people use nano-calcium, but 6602 wet method is also used to treat nano-calcium
