(1) Kuyeretsa zosungunulira za organic

Amagwiritsa ntchito zosungunulira za organic kuti asungunuke mafuta a saponified ndi unsaponified kuchotsa madontho amafuta.Zomwe zimagwiritsidwa ntchito kwambiri ndi organic solvents zimaphatikizapo ethanol, kuyeretsa mafuta, toluene, carbon tetrachloride, trichlorethylene, etc. Zosungunulira zothandiza kwambiri ndi carbon tetrachloride ndi trichlorethylene, zomwe sizidzawotcha ndipo zingagwiritsidwe ntchito kuchotsa mafuta pa kutentha kwakukulu.Tiyenera kukumbukira kuti pambuyo pochotsa mafuta ndi organic solvent, kuchotsa mafuta owonjezera kuyeneranso kuchitidwa.Pamene zosungunulira volatilizes pamwamba pachubu lamakona anayi, nthawi zambiri pamakhala filimu yopyapyala yotsalira, yomwe imatha kuchotsedwa m'njira zotsatirazi monga kuyeretsa alkali ndi kuchotsa mafuta a electrochemical.

(2) Kuyeretsa kwa Electrochemical

Kuchotsa mafuta a cathode kapena kugwiritsa ntchito anode ndi cathode kumagwiritsidwa ntchito kwambiri.Mpweya wa haidrojeni wolekanitsidwa ndi cathode kapena mpweya wa okosijeni wolekanitsidwa ndi anode ndi electrochemical reaction umakanikizidwa ndi yankho pamwamba pachubu lamakona anayikulimbikitsa banga lamafuta kuti lithawe pamwamba pazitsulo.Panthawi imodzimodziyo, yankholo limasinthidwa mosalekeza, zomwe zimathandiza kuti saponification reaction ndi emulsification ya mafuta.Mafuta otsalawo adzalekanitsidwa ndi chitsulo pamwamba pa chikoka cha ma thovu olekanitsidwa mosalekeza.Komabe, mkati mwa cathodic degreasing, haidrojeni nthawi zambiri imalowa muzitsulo, zomwe zimapangitsa kuti hydrogen imbrittlement.Pofuna kupewa hydrogen embrittlement, cathode ndi anode nthawi zambiri amagwiritsidwa ntchito kuchotsa mafuta mosinthana.

(3) Kuyeretsa zamchere

Njira yoyeretsera pogwiritsa ntchito mankhwala a alkali imagwiritsidwa ntchito kwambiri chifukwa chosavuta kugwiritsa ntchito, mtengo wotsika komanso kupezeka mosavuta kwa zipangizo.Popeza njira yotsuka ya alkali imadalira saponification, emulsification ndi ntchito zina, alkali imodzi singagwiritsidwe ntchito kukwaniritsa zomwe zili pamwambazi.Zigawo zosiyanasiyana zimagwiritsidwa ntchito nthawi zambiri, ndipo zowonjezera monga ma surfactants nthawi zina zimawonjezeredwa.The alkalinity imatsimikizira kuchuluka kwa saponification reaction, ndipo alkalinity yayikulu imachepetsa kusamvana kwapakati pakati pa mafuta ndi yankho, kupangitsa mafuta kukhala osavuta kuyika.Komanso kuyeretsa wothandizila otsala pamwamba parectangular dzenje gawoakhoza kuchotsedwa ndi kutsuka madzi pambuyo kutsuka alkali.

(4) Kuyeretsa kwapamtunda

Ndi njira yomwe imagwiritsidwa ntchito kwambiri pochotsa mafuta pogwiritsa ntchito mawonekedwe a surfactant monga kutsika kwapamtunda, kunyowa bwino komanso kuthekera kolimba kwa emulsifying.Kudzera mu emulsification wa surfactant, ndi interfacial nkhope chigoba ndi mphamvu zina aumbike pa mawonekedwe mafuta-madzi kusintha mawonekedwe a mawonekedwe, kuti particles mafuta omwazika mu amadzimadzi njira kupanga emulsion.Kapena kupyolera mu kusungunuka kwa surfactant, banga la mafuta silisungunuka m'madzi pachubu lamakona anayiamasungunuka mu surfactant micelle, kuti asamutse banga lamafuta ku njira yamadzi.
