Ukuze imveliso yenziwe ibe yeyakho ngakumbi, uninzi lweemveliso zokupakisha ezenziweyo kufuneka zifakwe umbala womphezulu. Kukho iinkqubo ezahlukeneyo zonyango lomphezulu zokupakisha iikhemikhali zemihla ngemihla. Apha sazisa ikakhulu iinkqubo ezininzi eziqhelekileyo kushishino lokupakisha izithambiso, ezinje ngokugquma nge-vacuum, ukutshiza, ukufakelwa nge-electroplating, ukufutha, ukubumba ngenaliti kunye nokutshintsha umbala.
1. Inkcazo yenkqubo yokwaleka ngeVacuum
I-vacuum coating ibhekisa kakhulu kuhlobo lwemveliso ekufuneka igqunywe phantsi kweqondo eliphezulu le-vacuum. I-substrate yefilimu eza kufakwa igqunywe ifakwa kwi-vacuum evaporator, kwaye ipompo ye-vacuum isetyenziselwa ukukhupha i-vacuum kwi-coating ukuya kwi-1.3 × 10-2 ~ 1.3 × 10-3Pa. I-crucible iyafudunyezwa ukuze inyibilike kwaye ikhuphe i-high-purity aluminium wire (purity 99.99%) kubushushu be-1200 ℃ ~ 1400 ℃ kwi-gaseous aluminium. Amasuntswana e-gaseous aluminium afakwa kumphezulu we-substrate yefilimu ehambayo, kwaye emva kokupholisa nokunciphisa, kwenziwa umaleko we-aluminium yesinyithi oqhubekayo nokhanyayo.
2. Iimpawu zenkqubo yokwaleka ngeVacuum
Ixabiso lenkqubo: ixabiso lesikhunta (akukho), ixabiso leyunithi (eliphakathi)
Imveliso efanelekileyo: iqhekeza elinye ukuya kwibhetshi enkulu
Umgangatho: umgangatho ophezulu, ukukhanya okuphezulu kunye nomaleko wokukhusela umphezulu wemveliso
Isantya: isantya esiphakathi semveliso, iiyure ezi-6 ngomjikelo (kuquka ukupeyinta)
3.Ukwakhiwa kwenkqubo yenkqubo yokugquma nge-vacuum
1. Izixhobo zokufaka i-electroplating
I-vacuum plating yeyona ndlela ixhaphakileyo yokulungisa umphezulu wesinyithi. Ekubeni kungekho mfuneko yokubumba, iindleko zenkqubo ziphantsi kakhulu, kwaye imibala efana nempilo ingasetyenziswa nakwi-vacuum plating, ukuze umphezulu wemveliso ufezekise isiphumo se-aluminium eyosiweyo, i-chrome ekhanyayo, igolide, isilivere, ubhedu kunye ne-gunmetal (i-alloy ye-copper-tin). I-vacuum plating inganyanga umphezulu wezinto ezingabizi (ezifana ne-ABS) kwisiphumo somphezulu wesinyithi ngexabiso eliphantsi. Umphezulu we-vacuum plated workpiece kufuneka ugcinwe womile kwaye uthambile, kungenjalo kuya kuyichaphazela kakhulu impembelelo yomphezulu.
2. Izinto ezisebenzayo
Izinto zesinyithi zinokuba yigolide, isilivere, ubhedu, i-zinc, i-chromium, i-aluminium, njl.njl., phakathi kwazo i-aluminium yeyona isetyenziswa kakhulu. Izinto zeplastiki nazo ziyasebenza, ezifana ne-ABS, njl.njl.
4. Isalathiso sokuhamba kwenkqubo
Masithathe inxalenye yeplastiki njengomzekelo: fafaza umaleko weprimer kwindawo yokusebenza kuqala, uze emva koko wenze i-electroplating. Ekubeni indawo yokusebenza iyinxalenye yeplastiki, amaqamza omoya kunye neegesi eziphilayo ziya kuhlala ngexesha lokubumba ngenaliti, kwaye umswakama emoyeni uya kutsalwa xa ubekwa. Ukongeza, ekubeni umphezulu weplastiki ungathanga tyaba ngokwaneleyo, umphezulu wento yokusebenza awugudileyo, ukukhanya kuphantsi, imvakalelo yesinyithi ayilunganga, kwaye kuya kubakho amaqamza, amaqamza kunye nezinye iimeko ezingafunekiyo. Emva kokutshiza umaleko weprimer, kuya kwenziwa umphezulu ogudileyo nothe tyaba, kwaye amaqamza kunye namaqamza akhoyo kwiplastiki ngokwayo aya kususwa, ukuze isiphumo se-electroplating sibonakale.
5.Isicelo kwishishini lokupakisha izithambiso
I-vacuum coating inezicelo ezahlukeneyo kushishino lokupakisha izinto zokuhombisa, ezifana nezixhobo zangaphandle zetyhubhu ye-lipstick, izixhobo zangaphandle zentloko yepompo, iibhotile zeglasi, izixhobo zangaphandle zesiciko sebhotile, njl.njl.
