Detailed Description
Calcium carbonate 98.6%
CAS No.:471-34-1 Content: 98.6% active 98.6% lightweight formula:CaCO3 relative molecular mass :100.09 melting point: 825° C density: 2.93 g/cm3 moh’s hardness :3 decomposition temperatures :898° C Melting point: when the pressure for10.4 MPaJF, melting point for 1339° C solubility don’t soluble in water, don’t soluble in ethanol. Dielectric constant: 7.5-8.8 properties: white crystals or powder. Tasteless. Put in air no response, not soluble in ethanol. Encounter dilute acetic acid, nitric acid, hydrochloric acid dissolution occurred bubble boiling. In 101.325 MPaJF when heated to 900 ° C decomposed into CaO and carbon dioxide. Purposes: 1, less than 200 meshes, can be applied to various feed additive quantity of 55.6 above without harmful ingredients 2, 250 meshes to 300 meshes: used as plastic factory, rubber factory, waterproof coating factory, the raw materials and external paint job. White degrees in more than 85 degrees. 3, 350 mesh to 400 mesh is used in the manufacturing of the gusset plate, into the pipeline, chemicals. White degrees in 93 degrees. 4, 400 mesh to 600 mesh: can be used for toothpaste, paste soap. White degrees in 94 degree above 5, 800 mesh: used for rubber, plastic, cable, PVC whiteness was 94 degrees 6, 1250 mesh: PVC, PE, paint, paint level product, the papermaking, the papermaking surface coating, with white degree in 95 degrees above. With high purity and high whiteness, non-toxic, odurless, fine oleaginous low, hardness is low. 7. Calcium carbonate can make calcium supplement: absorption rate can amount to 39 percent, second only to fruit acid calcium soluble in stomach acid, has become the most most, application form, calcium supplement. 8. Calcium carbonate, used for improvement in alkaline acid soils
