(1) Organic solvent yekuchenesa

Inonyanya kushandisa organic solvents kunyungudutsa saponified uye unsaponified mafuta kubvisa mafuta mavara. Iyo inowanzoshandiswa organic solvents inosanganisira ethanol, kuchenesa peturu, toluene, carbon tetrachloride, trichlorethylene, etc. Izvo zvinonyanya kushanda zvinonyungudutsa carbon tetrachloride uye trichlorethylene, iyo isingapisi uye inogona kushandiswa kubvisa mafuta pakupisa kwepamusoro. Izvo zvinofanirwa kucherechedzwa kuti mushure mekubviswa kwemafuta ne organic solvent, kubviswa kwemafuta ekuwedzera kunofanirawo kuitwa. Kana iyo solvent inoputika pamusoro perectangular chubhu, kazhinji pane firimu yakaonda yakasara, iyo inogona kubviswa mumatanho anotevera akadai sekuchenesa alkali uye kubviswa kwemafuta e electrochemical.

(2) Electrochemical cleaning

Kubviswa kwemafuta eCathode kana kumwe kushandiswa kweanode uye cathode kunonyanya kushandiswa. Iyo hydrogen gasi yakapatsanurwa kubva kune cathode kana iyo okisijeni gasi yakapatsanurwa kubva kune anode ne electrochemical reaction inomutswa nemagetsi nemhinduro iri pamusoro pemvura.rectangular chubhukukurudzira kusvibiswa kwemafuta kutiza kubva panzvimbo yesimbi. Panguva imwecheteyo, mhinduro inoramba ichitsinhaniswa, iyo inobatsira kune saponification reaction uye emulsification yemafuta. Mafuta akasara achaparadzaniswa nesimbi pasi pesimba rezvinoramba zvakaparadzana mabhubhu. Zvisinei, mukuita kwe cathodic degreasing, haidrojeni inowanzopinda musimbi, zvichiita kuti hydrogen imbrittlement. Kuti udzivise hydrogen embrittlement, iyo cathode uye anode inowanzoshandiswa kubvisa mafuta neimwe nzira.

(3) Alkaline kuchenesa

Nzira yekuchenesa yakavakirwa pamakemikari chiito chealkali inoshandiswa zvakanyanya nekuda kwekushandiswa kwayo nyore, mutengo wakaderera uye kuwanikwa nyore kwezvinhu zvakasvibiswa. Sezvo iyo alkali yekugeza maitiro zvinoenderana ne saponification, emulsification uye mamwe mabasa, imwe alkali haigone kushandiswa kuita iri pamusoro pekuita. Zvakasiyana-siyana zvezvikamu zvinowanzoshandiswa, uye zvinowedzera zvakadai sema surfactants dzimwe nguva zvinowedzerwa. Iyo alkalinity inosarudza dhigirii resaponification reaction, uye iyo yakakwira alkalinity inoderedza kusawirirana kwepamusoro pakati pemafuta nemhinduro, zvichiita kuti mafuta ave nyore kumisa. Mukuwedzera, mumiririri wekuchenesa anoramba ari pamusoro perectangular hollow chikamuinogona kubviswa nekugeza mvura mushure mekugeza alkali.

(4) Surfactant kuchenesa

Iyo inowanzoshandiswa nzira yekubvisa mafuta nekushandisa hunhu hwe surfactant senge yakaderera pasi tension, yakanaka kunyorova uye yakasimba emulsifying kugona. Kuburikidza ne emulsification ye surfactant, chifukidzo chechiso chemukati chine simba rakati chinoumbwa pa-oiri-mvura interface kuti ichinje mamiriro ekugadzirisa, kuitira kuti zvimedu zvemafuta zvinoparadzirwa mumushonga wemvura kuti uite emulsion. Kana kuburikidza nekunyungudika kwekuita kwe surfactant, iyo mafuta tsvina isinganyungudika mumvura parectangular chubhuinonyungudika mu surfactant micelle, kuitira kuendesa tsvina yemafuta kune mhinduro ine aqueous.
