Ukugqoka nge-electrophoretickufana nezinye izindlela zokumboza. Izingxenye ezimbozwe zidinga ukuphathwa ubuso ngaphambi kokumboza. Ukwelashwa kwendawo kuwumsebenzi obalulekile okudingeka wenziwe ngaphambi kokumboza. Izindlela ezahlukene zokumboza, izinto ezahlukene kanye nezimo zazo zobuso, ngakho-ke izinqubo nezindlela zokwelapha indawo ezidingekayo azifani. Izinqubo ezahlukene zokwelapha indawo kanye nekhwalithi yokwelapha azithinti nje kuphela ikhwalithi yokumboza, kodwa futhi nezindleko zokwelapha indawo zinomthelela omkhulu. Ngakho-ke, lapho senza umklamo wobuchwepheshe, kumele sikhethe indlela yokufaka, izinto kanye nesimo sobuso bezingxenye ezimbozwe, kanye nenqubo yokwelapha indawo kanye nendlela enokufaneleka okuqinile, umphumela omuhle wokwelapha kanye nezindleko eziphansi kakhulu ngangokunokwenzeka.
Kungani i-electrophoresis inenqubo yangaphambi kokwelashwa?
Enqubweni yokwelashwa ngaphambi kokwelashwa kwe-electrophoresis, kuba nokubambisana kokubili kokususa amafutha, ukususa ukugqwala, i-phosphate, ukulungiswa kwendawo kanye nezinye izinqubo. Kungashiwo ukuthi ukwelashwa kwangaphambili kubalulekile ekumbozweni kwe-electrophoretic, okuhlobene nokuzinza kwebhavu lokupenda le-electrophoretic ngemva kwe-electrophoresis kanye nekhwalithi yefilimu yokumboza ebusweni bento yokusebenza.
Ukuze kutholakale ukuqina kanye nokumelana nokugqwala kwefilimu yokumboza ye-electrophoretic workpiece, ukwelashwa nge-phosphating kusetshenziswa njengendlela yokwelapha ngaphambi kokumboza. Ukwelashwa nge-phosphate (okwaziwa nangokuthi ukwelashwa ngamakhemikhali e-phosphate) ubuchwepheshe (befilimu yokumboza) obusebenzisa ukusabela kwe-dissociation (equilibrium) kwe-phosphoric acid ukuze kuqhutshwe usawoti wensimbi we-phosphate onganyibiliki ebusweni bezinsimbi zensimbi ezihlanziwe (ezingagcotshwanga). Umsebenzi wefilimu yokumboza ukuthuthukisa ukunamathela kanye nokumelana nokugqwala kwefilimu yokumboza (i-electrophoretic coating) esetshenziswa kuyo.
Ngokuphathelene nokunamathela, amakristalu efilimu ye-phosphide etholakele ancibilika kancane ebusweni bensimbi, futhi ukunamathela kwamakristalu kuhle. Ngaphezu kwalokho, indawo yobuso iyanda ngenxa yokungalingani kobuso bamakristalu amaningi, futhi ukunamathela kwefilimu yokumboza kuyathuthuka. Ngemuva kwalokho, ngokuthuthukiswa kokunamathela kwefilimu yokumboza, ukungena kwezinto ezikhiqiza ukugqwala kuyavinjelwa, futhi ukumelana nokugqwala kuyathuthuka (ikakhulukazi ukwanda kokugqwala ngaphansi kwefilimu yopende kungavinjelwa).
Isembozo sizoqhuma futhi sigqwale esikhathini esifushane ngaphandle kwe-phosphating. Amanzi nomoya odlula efilimini yokumboza kufinyelela ebusweni bento yokusebenza ukuze kwakheke ukugqwala okubomvu futhi kuvuvuke ifilimu yopende. Amanzi nomoya odlula efilimini yokumboza kufinyelela eshidini lensimbi elihlanganisiwe ukuze kwakheke ukugqwala okumhlophe, okuphinde kuhlangane nefilimu yokumboza ukuze kwakheke insipho yensimbi. Iphindwe kaningana, ukuze ifilimu yokumboza ikhukhumale ngamandla. Ifilimu yokumboza iyifilimu enganyibiliki eyakhiwe ebusweni bensimbi ngokusabela kwamakhemikhali. Ngenxa yokunamathela kwayo okuhle (ngokomzimba) kanye nokuzinza kwamakhemikhali, iphathwa njengesisekelo sokumboza esiqinile esilwa nokugqwala.
Ukuze uthole ifilimu ye-phosphating enhle kakhulu futhi ezinzile futhi uqinisekise ukunamathela kwayo kanye nokumelana nokugqwala, ukuphathwa kokwelashwa kwangaphambi kwesikhathi kubaluleke kakhulu. Ngesikhathi esifanayo, kubalulekile ukuqonda kahle indlela eyisisekelo yokusabela kanye nezakhi zokwelashwa kwe-phosphating.
