Emakethe kawoyela odliwayo, uwoyela ocindezelwe namafutha akhishiwe yizinhlobo ezimbili eziyinhloko zikawoyela. Zombili ziphephile ukuthi zisetshenziswe inqobo nje uma zithobela izinga likawoyela odliwayo kanye nezindinganiso zokuhlanzeka. Kodwa-ke, kunomehluko omkhulu phakathi kwalokhu kokubili mayelana namasu okucubungula, okuqukethwe okunomsoco, kanye nezidingo zempahla eluhlaza.
1. Umehluko Kumasu Okucubungula
Amafutha Acindezelwe:
Amafutha acindezelwe akhiqizwa kusetshenziswa indlela yokucindezela ngokomzimba. Le nqubo ihilela ukukhetha izimbewu zikawoyela zekhwalithi ephezulu, okulandelwa izinyathelo ezinjengokugxoba, ukugazinga, nokucindezela ukuze kukhishwe uwoyela. Uwoyela ongahluziwe ube usuhlungwa futhi ucwengisiswe ukuze kukhiqizwe uwoyela ocindezelwe osezingeni eliphezulu. Le ndlela igcina iphunga lemvelo likawoyela kanye nokunambitheka, okuholela ekubeni umkhiqizo oneshalofu isikhathi eside futhi ungabi nazo izithasiselo noma izincibilikisi ezisalela.
Amafutha Akhishiwe:
Amafutha akhishiwe akhiqizwa kusetshenziswa indlela yokukhipha amakhemikhali, esebenzisa izimiso zokukhishwa okusekelwe ku-solvent. Le nqubo yaziwa ngezinga layo eliphezulu lokukhipha uwoyela kanye nomfutho ophansi wokusebenza. Kodwa-ke, uwoyela ongahluziwe okhishwa ngale ndlela udlula ezinyathelweni eziningi zokucutshungulwa, okuhlanganisa ukuchithwa kwewaxing, ukukhishwa kwegumming, ukukhipha amanzi emzimbeni, ukuqeda iphunga, ukuqeda iacid, nokukhipha umbala, ngaphambi kokuthi usetshenziswe. Lezi zinqubo ngokuvamile zilulaza izithako zemvelo emafutheni, futhi amanani amancane ezinto ezincibilikisiwe ezisele angase asale emkhiqizweni wokugcina.
2. Umehluko Kokuqukethwe Okunomsoco
Amafutha Acindezelwe:
Amafutha acindezelwe agcina umbala wemvelo, iphunga, ukunambitheka, kanye nezakhi zomsoco zembewu yamafutha. Lokhu kwenza kube inketho enempilo futhi enambitheka kakhudlwana.
Amafutha Akhishiwe:
Uwoyela okhishiwe ngokuvamile awunambala futhi awunaphunga. Ngenxa yokucutshungulwa kwamakhemikhali okubanzi, inani elikhulu lokudla okunomsoco okungokwemvelo liyalahleka.
3. Umehluko Ezimfuneko Zempahla Engavuthiwe
Amafutha Acindezelwe:
Ukucindezela ngokomzimba kudinga izimbewu zikawoyela zekhwalithi ephezulu. Izinto ezisetshenziswayo kufanele zibe zintsha, zibe ne-asidi ephansi ne-peroxide, ukuqinisekisa ukuthi uwoyela wokugcina ugcina iphunga lawo lemvelo kanye nokunambitheka. Le ndlela iphinde ishiye inani eliphezulu likawoyela eliyinsalela ekhekheni lembewu yamafutha, okuholela ekukhiqizweni kwesivuno sikawoyela esiphelele. Ngenxa yalokho, uwoyela ocindezelwe uvame ukubiza kakhulu.
Amafutha Akhishiwe:
Ukukhishwa kwamakhemikhali kunezidingo eziqinile zezinto ezingavuthiwe, okuvumela ukusetshenziswa kwezimbewu zikawoyela ezinamaleveli ekhwalithi ahlukahlukene. Lokhu kunomthelela ekuvuthweni kwamafutha aphezulu kanye nezindleko eziphansi, kodwa ngezindleko zokunambitheka kwemvelo nokudla.
