1. Sicela ubheke isingeniso somkhiqizo ukukhetha imodeli yomkhiqizo efanelekile kanye nokucaciswa ukugwema ukwehluleka ukusebenzisa ngenxa yezimpawu ezingekho emthethweni.

2. Lapho ethola izimpahla, qinisekisa isisindo nokuthi ibhokisi elingaphandle lichobozekile, lilimele, lifakwe amazinyo noma likhubazekile; Esezinhlelweni zokuphatha, kufanele kusingathwe ngokunakekela ukugwema ukudlidliza ukwenza ukudlidliza kwenze ikhebula liwe phansi lizonke, okuholela ekubizeni kwentambo, kunamathele.

3. Ngesikhathi sokugcina, naka ukugwema ukuvikela, uvikele ekubenihlotshiswe futhi uchotshozwe ngensimbi nezinye izinto ezinzima, futhi uvimbele ukugcinwa okuxubile nge-organic solvent, i-arkali enamandla noma i-alkali. Imikhiqizo engasetshenziswanga kufanele igoqwe ngokuqinile futhi igcinwe kwiphakheji yangempela.

I-4. Ucingo olwenziwe ngalo kufanele lugcinwe endaweni yokugcina izinto enomoya owawungena uthuli (kufaka phakathi uthuli lwensimbi). Ukukhanya kwelanga okuqondile akuvunyelwe ukugwema izinga lokushisa eliphakeme nomswakama. Imvelo yokugcina engcono kakhulu yile: izinga lokushisa ≤50 ℃ kanye nomswakama ohlobene ≤ 70%.

5 Ungathinti i-wire enameded ngqo ngesandla sakho.

6. Ngesikhathi senqubo yokususa umoya, i-spool kufanele ifakwe kwikhava ekhokhelwa ngangokunokwenzeka ukugwema ukulimala kocingo noma ukungcoliswa kwe-solvent; Enqubweni yokukhokha, ukungezwani okuvuthayo kufanele kulungiswe ngokuya ngethebula lokungezwani kwezokuphepha, ukuze ugweme ukuqhekeka kwe-wire noma i-wire ebuhlungu okubangelwa ukungezwani ngokweqile, futhi ngasikhathi sinye, kugweme ukuxhumana ngopende ukulimala kwefilimu kanye nomjikelezo omubi ompofu.

7. Nakisisa ukugxila kanye nenani le-solvent (i-methanol ne-ethanol anhydrous anconyiwe) lapho ehlanganisa i-solvent efake umugqa wokuzifaka amandla, futhi unake ukulungiswa kwebanga phakathi kwepayipi elishisayo nomoya kanye nokushisa lapho ukuhlanganisa umugqa oshisayo oshisayo onamathela.
