Permeability of Oil Films with Molecules of Water, Sulfur(IV) Oxide, and Oxygen
2019
At room temperature, moisture, SO2, and oxygen permeability of mineral oils, i.e., industrial I‑20A, M-10G2(K) (product and waste, MWO), rapeseed, and sunflower are studied. It is shown that all the studied oils are highly permeable to H2O, SO2, and O2 molecules. For the moisture and SO2 permeability of the studied oils, the following dependences are typical: m(H2O) = ai + biτ and m(SO2) = li + kiτ. The values of ai and li are determined by the nature of the base solvent and the concentration of thickeners (PVK, IFKhAN-29A), which can both suppress and stimulate oxygen permeability.
