FILTER ELEMENT FOR FILTRATION OF A LIQUID Russian patent published in 2021 - IPC B01D29/00 B01D29/07 B01D29/11 B01D35/28 E21B43/08

Abstract RU 2763134 C1

FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering, namely, to filter elements used as part of filters for purifying liquid media. The filter element for filtration of a liquid is made of metal, applied whereon is a hydrophobic coating based on organofluorine compounds. Said coating additionally exhibits oleophobic properties and comprises an organosilicon binder in the composition thereof. Fluorosilane – CF₃-(CF₂)₅-C(O)-HN-(CH₂)₃-Si(OC₂H₅)₃ or a copolymer of 1,1-dihydroperfluoroheptilacrylate, N-methylolmethacrylamide, and N-trimethylammonium ethylmethacrylate methylsulphate is used as an organofluorine compound.

EFFECT: implementation of the invention allows for an increase in the reliability and the operating life of the filter element.
