I-Electrophoretic coatingiyafana nezinye izindlela zokumboza. Izingxenye ezimboziwe zidinga ukuphathwa phezulu ngaphambi kokumbozwa. Ukwelashwa okungaphezulu kuwumsebenzi obalulekile okudingeka wenziwe ngaphambi kokumboza. Izindlela ezihlukene zokumboza, izinto ezihlukene kanye nezimo zabo ezingaphezulu, ngakho Izinqubo nezindlela zokwelashwa ezidingekayo azifani. Akukhona nje kuphela ukuthi izinqubo ezahlukene zokwelashwa kwendawo kanye nekhwalithi yokwelashwa kuthinta kakhulu ikhwalithi yokumboza, kodwa futhi izindleko zokwelashwa kwendawo zinomthelela omkhulu. Ngakho-ke, lapho senza umklamo wobuchwepheshe, kufanele kukhethwe indlela yokufaka, impahla kanye nesimo sendawo yezingxenye ezimboziwe, kanye nenqubo yokwelapha engaphezulu kanye nendlela eqinile, umphumela omuhle wokwelapha kanye nezindleko eziphansi kufanele kukhethwe ngangokunokwenzeka. .
Kungani i-electrophoresis inenqubo yokwelapha ngaphambi kwesikhathi?
Enqubweni yokwelashwa kwangaphambili kwe-electrophoresis, kukhona ukubambisana okuhlangene kokukhipha amafutha, ukususwa kokugqwala, i-phosphating, ukulungiswa kwendawo nezinye izinqubo. Kungashiwo ukuthi ukwelapha kusengaphambili kubalulekile ekuhlanganiseni kwe-electrophoretic, okuhlobene nokuzinza kokugeza ngopende we-electrophoretic ngemva kwe-electrophoresis kanye nekhwalithi yefilimu yokumboza ebusweni bomsebenzi.
Ukuze uthole ukuqina nokumelana nokugqwala kwefilimu yokumboza ye-electrophoretic workpiece, ukwelashwa kwe-phosphating kusetshenziswa njengokwelashwa kwangaphambili kokumboza. Ukwelashwa kwe-phosphating (okubuye kwaziwe ngokuthi i-phosphate chemical treatment) ubuchwepheshe (ifilimu ye-phosphating) obusebenzisa ukusabela kwe-dissociation (equilibrium) kwe-phosphoric acid ukuze kuncishiswe usawoti wensimbi we-phosphate ongancibilikiyo phezu kwezingqimba zensimbi ezihlanziwe (ezehlisiwe). Umsebenzi wefilimu ye-phosphating ukuthuthukisa ukunamathela nokumelana nokugqwala kwefilimu yokugqoka (i-electrophoretic coating) esetshenziswe kuyo.
Ngokuphathelene nokunamathela, amakristalu efilimu ye-phosphide etholiwe ancibilika kancane endaweni yensimbi, futhi ukunamathela kwamakristalu kuhle. Ngaphezu kwalokho, indawo engaphezulu iyanda ngenxa yokungalingani kwendawo yamakristalu amaningi, futhi ukunamathela kwefilimu yokugqoka kuyathuthukiswa. Khona-ke, ngokuthuthukiswa kokunamathela kwefilimu yokugqoka, ukungena kwezinto ezikhiqiza ukugqwala kuvinjelwe, futhi ukumelana nokugqwala kuthuthukisiwe (ikakhulukazi ukwandiswa kokugqwala ngaphansi kwefilimu yokupenda kungavinjelwa).
I-coating izoqhuma futhi igqwale ngesikhathi esifushane ngaphandle kwe-phosphating. Amanzi nomoya odlula ifilimu yokumboza kufinyelela phezu kwendawo yokusebenza ukuze kwakheke ukugqwala okubomvu futhi kuvuvuke ifilimu kapende. Amanzi nomoya odlula efilimini enamathelayo kufinyelela eshidini lensimbi ukuze kwakheke ukugqwala okumhlophe, okubuye kuhlangane nefilimu yokunameka kwenze insipho yensimbi. Izikhathi ezimbalwa ezinkulu, ukuze ifilimu yokugqoka ikhukhumeze ngamandla. Ifilimu ye-Phosphating ifilimu engancibilikiyo eyakhiwe phezu kwensimbi ngokusabela kwamakhemikhali. Ngenxa yokunamathela kwayo okuhle (ngokomzimba) nokuzinza kwamakhemikhali, iphathwa njenge-substrate eqinile evimbela ukugqwala.
Ukuze uthole ifilimu ye-phosphating enhle kakhulu futhi ezinzile futhi uqinisekise ukumelana kwayo nokunamathela nokugqwala, ukuphathwa kokwelashwa kwangaphambili kubaluleke kakhulu. Ngasikhathi sinye, kuyadingeka ukuqonda kahle indlela eyisisekelo yokusabela kanye nezakhi zokwelashwa kwe-phosphating.
