Umsebenzi wokulungiswa kwangaphambili kwe-vacuum coating ikakhulu ubandakanya la manyathelo alandelayo, ngalinye lithatha indima ethile ukuqinisekisa umgangatho kunye nesiphumo senkqubo yokwambathisa:
No.1 Amanyathelo onyango lwangaphambili
1. Ukusila umphezulu kunye nokupholisha
Sebenzisa i-abrasives kunye ne-polish agents ukuze usebenze ngobuchwephesha umphezulu weendawo ezicwengiweyo ukuze ususe i-microstructure erhabaxa yomphezulu kwaye ufezekise iqondo elithile lokugqiba.
Umsebenzi: Phucula ukubambelela kunye nokufana kwengubo, yenza umphezulu wengubo ube lula kwaye uhle ngakumbi.
2.Ukwehlisa amafutha
Yamkela ukunyibilika kwe-solvent, iikhemikhali okanye iindlela ze-electrochemical zokususa igrisi kunye neoyile kumphezulu weendawo ezicwecwe.
Umsebenzi: Ukuthintela ioli kunye negrisi ekuveliseni ama-bubbles, i-flaking kunye nezinye iziphene kwinkqubo yokugqoka, kwaye uphucule ukunamathela kwengubo.
3.Ukucoca
Sebenzisa i-asidi, i-alkali, i-solvents kunye nezinye isisombululo semichiza ukucwiliswa okanye i-ultrasonic, i-plasma yokucoca iindawo ezicwecwe ukususa i-oxides yomhlaba, i-rust kunye nezinye izinto ezingcolileyo.
Indima: ukucoca ngakumbi umphezulu weendawo ezicwecwe, ukuqinisekisa ukuba izinto zokugquma kunye ne-substrate phakathi kokudibanisa okusondeleyo.
4.Unyango olusebenzayo
Hlulisa umphezulu wamacandelo acwecwe kwi-asidi ebuthathaka okanye isisombululo esikhethekileyo sokususa i-passivation layer phezu komgangatho kunye nokuphucula umsebenzi womphezulu.
Indima: ukukhuthaza ukusabela kweekhemikhali okanye ukudityaniswa komzimba phakathi kwezinto zokwaleka kunye nomgangatho ocwecwe, ukuphucula indibaniselwano kunye nokuqina kwengubo.
No.2 indima yonyango lwangaphambili
1. Ukuphucula umgangatho wokugquma
Unyango lwangaphambili lunokuqinisekisa ukuba umphezulu weendawo ezicwengiweyo zicocekile, zigudile kwaye azinanto engcolileyo, ehambelana nokufakwa okufanayo kwezinto zokugubungela kunye nokudibanisa okusondeleyo.
Oku kunceda ekuphuculeni i-adhesion yokwambathisa, ukufana kunye nobulukhuni kunye nezinye izalathisi zokusebenza.
2. Lungiselela inkqubo yokwaleka
Inkqubo yokulungiswa kwangaphambili inokulungelelaniswa ngokwezinto eziphathekayo zamacandelo kunye neemfuno zokugquma ukulungelelanisa iinkqubo ezahlukeneyo zokugubungela kunye nezixhobo.
Oku kunceda ukunyusa iiparameters zenkqubo yokwambathisa kunye nokuphucula imveliso kunye nomgangatho wokugquma.
3. Ukunciphisa iziphene zokugquma
Ukunyangwa kwangaphambili kunokususa i-oxides, izicubu ezikhululekile, i-burrs kunye nezinye izakhiwo phezu kwendawo edibeneyo, ukukhusela ezi zakhiwo ukuba zibe ngumthombo weziphene ngexesha lenkqubo yokugubungela.
Oku kunceda ukunciphisa ama-bubbles, i-flaking, i-cracks kunye nezinye iziphene kwinkqubo yokugqoka, kunye nokuphucula i-aesthetics kunye nokusetyenziswa kwengubo.
4. Qinisekisa ukhuseleko lwemveliso
Amanyathelo okucoca i-oyile kunye nokucoca iikhemikhali kwinkqubo yokulungiswa kwangaphambili kunokususa izinto ezinokutsha kunye neziqhushumbisi kunye nezinto ezinobuthi ezinobuthi kunye nezinobungozi phezu kwendawo edibeneyo.
Oku kunceda ukunciphisa umngcipheko womlilo, uqhushumbo okanye ungcoliseko lwendalo kunye nezinye iingozi zokhuseleko kwinkqubo yokwaleka.
Isishwankathelo, umsebenzi owenziwe kwangaphambili we-vacuum coating uquka ukugaya umphezulu kunye nokupholisa, ukuchithwa kweoli, ukucocwa kweekhemikhali kunye namanyathelo okunyangwa okusebenzayo. Ngalinye lala manyathelo lithatha indima ethile yokuqinisekisa umgangatho kunye nokusebenza kwenkqubo yokugubungela. Ngokunyangwa kwangaphambili, umgangatho wokugquma unokuphuculwa, inkqubo yokwaleka inokuphuculwa, iziphene zokugquma zingancitshiswa kwaye ukhuseleko lwemveliso lunokuqinisekiswa.
