Coated calcium carbonate powder (coated)

Calcium carbonate powder is naturally hydrophilic. This property creates a problem for many industrial uses. Stearic acid is used to make calcium carbonate molecules hydrophobic. For this purpose, a thin layer of stearic acid is used to cover calcium carbonate molecules Stearic acid is one of the most important organic basic materials in the chemical industry, which is a wax-like substance and a member of the fatty acid family. The chemical formula of stearic acid is CH3(CH2)16COOH. Given the chemical formula that has two free OH and O bonds at one end, these types of bonds help inorganic materials to have organic-like properties after reacting with this acid and become hydrophobic in the sense. An important property of coated calcium carbonate powder is a significant reduction in oil absorption, reduction in particle aggregation and maximum filling of empty space, hydrophobicity, and ... Calcium carbonate is one of the best materials that is coated (coated) with stearic acid and works very well in this field. Coated calcium carbonate is considered a useful filler for polymer industries. Because coated calcium carbonate has a mineral base, combining calcium carbonate with polymer and plastic materials can facilitate the process of their absorption into nature, so the more we open up the place of fillers in the plastics industry, the easier it is to return these materials to nature. Benefits and how coated calcium carbonate powder is formed Ground calcium carbonate (GCC) – which has been created by nature over millions of years. Most calcium carbonate deposits are made up of the remains of marine organisms that have settled on the shallow sea floor. These organisms, such as crustaceans, algae, and corals, absorb calcium carbonate from the water and use it to form their skeletons and shells. When they die, their remains form sedimentary deposits on seabeds that build up over time. Calcium carbonate can also be produced artificially in the form of precipitable calcium carbonate (PCC). PCC is created by converting limestone into CaO and CO2 and then reacting the two purified components in a chemical reactor. The final product has the same chemical composition as GCC but is of higher purity and has different properties in terms of particle size distribution and particle shape. The high whiteness and opacity of carbonates lead to many applications from building materials to paper and paint, construction and food.
