Qha cov roj ntsha
Degreasant tsuas yog siv los tshem tawm cov nplaim ntawm cov roj, xws li: alkaline degreaser, emulsion degreaser thiab solvent degreaser peb.
(1) Alkaline degreaser, muaj li ntawm alkali, chelating agent thiab surfactant, nrog rau kev sib tov high-efficiency degreaser, high-kub muaj zog degreaser thiab li.
(2) Emulsion degreaser, uas yuav tshem tawm cov av ntawm lub npoo hlau los ntawm kev sib tsoo, txhaws taus, emulsification, thiab dispersibility ntawm surfactant; feem ntau yog ib qho ntawm cov anionic, cationic, thiab nonionic surfactants. Los yog ntau yam mixtures thiab diluted nrog dej ua ib qho emulsion.
(3) Cov kua degreasers, uas yog degreased los ntawm impregnation los yog steam. Cov tshuaj siv loj yog siv halogenated hydrocarbon solvents thiab cov tshuaj fluorinated hydrocarbon.
