Umsebenzi wokwelapha ngaphambi kokufaka i-vacuum coating uhlanganisa kakhulu izinyathelo ezilandelayo, ngasinye sazo sithatha indima ethile ukuqinisekisa ikhwalithi kanye nomphumela wenqubo yokufaka:
Izinyathelo zangaphambi kokwelashwa zeNombolo 1
1. Ukugaya nokupholisha ubuso
Sebenzisa ama-abrasives nama-ejenti okupholisha ukuze ucubungule ubuso bezingxenye ezifakwe ipulasitiki ngomshini ukuze ususe isakhiwo esincane sobuso futhi ufinyelele izinga elithile lokuqeda.
Umsebenzi: Thuthukisa ukunamathela kanye nokufana kwesembozo, yenza ubuso besembozo bube bushelelezi futhi bube buhle kakhudlwana.
2. Ukususa amafutha
Sebenzisa izindlela zokuncibilikisa isinyibilikisi, zamakhemikhali noma ze-electrochemical ukususa amafutha kanye namafutha ebusweni bezingxenye ezifakwe ipulasitiki.
Umsebenzi: Vimbela uwoyela namafutha ekukhiqizeni amabhamuza, ukuqhekeka kanye nezinye izinkinga enqubweni yokumboza, futhi uthuthukise ukunamathela kwemboza.
3. Ukuhlanza
Sebenzisa i-acid, i-alkali, izinyibilikisi kanye nezinye izixazululo zamakhemikhali noma ukuhlanza nge-ultrasonic, i-plasma yezingxenye ezifakwe amapulasitiki ukuze ususe ama-oxide angaphezulu, ukugqwala kanye nokunye ukungcola.
Indima: ukuhlanza kabanzi ubuso bezingxenye ezifakwe ipulasitiki, ukuqinisekisa ukuthi izinto zokumboza kanye ne-substrate ziphakathi kwenhlanganisela esondelene.
4. Ukwelashwa kokuvuselela
Gquma ubuso bezingxenye ezifakwe ipulasitiki nge-asidi ebuthakathaka noma isisombululo esikhethekile ukuze ususe ungqimba lokudlulisa phezu kobuso futhi uthuthukise umsebenzi wobuso.
Indima: ukukhuthaza ukusabela kwamakhemikhali noma inhlanganisela ebonakalayo phakathi kwezinto zokumboza kanye nobuso obumboziwe, ukuthuthukisa inhlanganisela nokuqina kwengubo.
Inombolo 2 indima yokwelashwa kwangaphambi kokwelashwa
1. Thuthukisa ikhwalithi yokumboza
Ukwelashwa kwangaphambi kwesikhathi kungaqinisekisa ukuthi ubuso bezingxenye ezifakwe ipulasitiki buhlanzekile, bubushelelezi futhi abunazo izinto ezingcolile, okusiza ukuthi izinto zokumboza zihlale zifana futhi zihlanganiswe ngokuseduze.
Lokhu kusiza ekuthuthukiseni ukunamathela kwesembozo, ukufana kanye nokuqina kanye nezinye izinkomba zokusebenza.
2. Lungiselela inqubo yokumboza
Inqubo yokwelashwa kwangaphambilini ingalungiswa ngokuya ngezinto zezingxenye ezifakwe ipulasitiki kanye nezidingo zokugqoka ukuze zivumelane nezinqubo nemishini ehlukene yokugqoka.
Lokhu kusiza ukwenza ngcono imingcele yenqubo yokumboza futhi kuthuthukise umkhiqizo kanye nekhwalithi yokumboza.
3. Nciphisa amaphutha okumboza
Ukwelashwa kusengaphambili kungasusa ama-oxide, izicubu ezikhululekile, ama-burrs nezinye izakhiwo ebusweni bezingxenye ezifakwe ipulasitiki, okuvimbela lezi zakhiwo ekubeni umthombo weziphambeko ngesikhathi senqubo yokumboza.
Lokhu kusiza ukunciphisa amabhamuza, ukuqhekeka, imifantu kanye nezinye izinkinga enqubweni yokumboza, futhi kuthuthukise ubuhle kanye nokusebenziseka kwemboza.
4. Qinisekisa ukuphepha kokukhiqiza
Izinyathelo zokususa amafutha nokuhlanza amakhemikhali enkambisweni yangaphambi kokwelashwa zingasusa izinto ezivuthayo neziqhumayo kanye nezinto ezinobuthi neziyingozi ebusweni bezingxenye ezifakwe ipulasitiki.
Lokhu kusiza ukunciphisa ingozi yomlilo, ukuqhuma noma ukungcola kwemvelo kanye nezinye izingozi zokuphepha enqubweni yokumboza.
Ngamafuphi, umsebenzi wokwelapha ngaphambi kokusebenzisa i-vacuum coating uhlanganisa ukugaya nokupholisha ubuso, ukususa amafutha, ukuhlanza amakhemikhali kanye nezinyathelo zokwelapha ukuze kusebenze. Izinyathelo ngasinye sithatha indima ethile ukuqinisekisa ikhwalithi kanye nokusebenza kahle kwenqubo yokugqoka. Ngokwelashwa ngaphambi kokusebenzisa, ikhwalithi yokugqoka ingathuthukiswa, inqubo yokugqoka ingathuthukiswa, amaphutha okugqoka angancishiswa futhi ukuphepha kokukhiqiza kungaqinisekiswa.
