Why does white powder precipitate on the surface of PP when calcium carbonate is added? Is there any way to solve it?

PP belongs to saturated olefin materials and is hydrophobic. Semi-hydrophilic material of heavy calcium. PP precipitated white powder, which was formed by hydrolysis of calcium carbonate in the presence of carbon dioxide. The solution is to treat the surface of heavy calcium with organic acids, such as stearic acid. If stearic acid is oxidized in air, it is also easy to hydrolyze.
