I-vacuum coating iyindlela lapho izinto zefilimu emincane zikhiqizwa ngezindlela ezingokwenyama.Ama-athomu ezinto ezisegunjini le-vacuum ahlukaniswa nomthombo wokushisisa futhi ashaye ingaphezulu lento ezogqitshwa.Lobu buchwepheshe baqala ukusetshenziswa ukukhiqiza amalensi okubona, njengamalensi ebonakude olwandle.Kamuva yanwetshwa kwamanye amafilimu asebenzayo, irekhodi le-aluminium plating, ukunamathela kokuhlobisa nokuguqulwa kwendawo ebonakalayo.Isibonelo, ikesi lewashi limbozwe ngegolide lokulingisa, futhi ummese womshini umbozwa ukushintsha ukucutshungulwa kobomvu nobulukhuni.
Isingeniso:
Isendlalelo sefilimu silungiswa endaweni engenalutho, okuhlanganisa i-plating crystalline metal, semiconductor, insulator, namanye amafilimu ayisisekelo noma ahlanganisiwe.Nakuba ukufakwa komhwamuko wamakhemikhali nakho kusebenzisa izindlela ze-vacuum ezifana nengcindezi encishisiwe, ingcindezi ephansi noma i-plasma, ukufakwa kwe-vacuum ngokuvamile kubhekisela ekusetshenzisweni kwezindlela ezibonakalayo ukuze kufakwe amafilimu amancane.Kunezinhlobo ezintathu ze-vacuum coating, okuyi-evaporation coating, i-sputtering coating kanye ne-ion plating.
Ubuchwepheshe be-vacuum coating baqala ukuvela ngeminyaka yawo-1930s, izicelo zezimboni zaqala ukuvela ngeminyaka yawo-1940 kanye nawo-1950, futhi ukukhiqizwa kwezimboni ezinkulu kwaqala ngawo-1980.Isetshenziswe kakhulu ezimbonini ezifana ne-electronics, i-aerospace, ukupakisha, ukuhlobisa, nokugxiviza okushisayo.I-vacuum coating ibhekisela ekufakweni kwensimbi ethile noma inhlanganisela yensimbi phezu kwempahla (imvamisa into engeyona eyensimbi) ngendlela yesigaba segesi endaweni yevacuum, okuyinqubo yokubeka umhwamuko obonakalayo.Ngenxa yokuthi ukugqoka ngokuvamile kuyifilimu yensimbi, kubizwa nangokuthi i-vacuum metallization.Ngomqondo obanzi, i-vacuum coating ihlanganisa nokufaka i-vacuum yamafilimu angasebenzi angewona ezensimbi njengamapholima angaphezulu kwensimbi noma izinto ezingezona ezensimbi.Phakathi kwazo zonke izinto okufanele zifakwe, ipulasitiki iyona evame kakhulu, ilandelwa ukumbozwa kwephepha.Uma kuqhathaniswa nezinsimbi, izitsha zobumba, izinkuni nezinye izinto, amapulasitiki anezinzuzo zemithombo eningi, ukulawula okulula kokusebenza, nokucubungula okulula.Ngakho-ke, izinhlobonhlobo zamapulasitiki noma ezinye izinto ze-polymer zisetshenziswa njengezinto zokwakha zokuhlobisa zobunjiniyela futhi zisetshenziswa kabanzi ezimotweni, ezintweni zikagesi zasendlini, nasekusetshenzisweni kwansuku zonke.Ukupakisha, ukuhlobisa izikebhe kanye neminye imikhakha yezimboni.Kodwa-ke, izinto eziningi zepulasitiki zineziphambeko ezinjengokuqina kobuso obuphansi, ukubukeka okwanele, nokumelana nokugqoka okuphansi.Isibonelo, ifilimu yensimbi encane kakhulu ingafakwa endaweni yepulasitiki ukunikeza ipulasitiki ukubukeka kwensimbi ekhanyayo.Kungakhuphula kakhulu ukumelana nokugqoka kobuso bezinto ezibonakalayo, futhi kwandise kakhulu umhlobiso kanye nobubanzi besicelo sepulasitiki.
Imisebenzi ye-vacuum coating inezici eziningi, okuphinde kunqume ukuthi izikhathi zayo zokufaka isicelo zicebile kakhulu.Ngokuvamile, imisebenzi eyinhloko ye-vacuum coating ihlanganisa ukudlulisela izinga eliphezulu lokucwebezela kwensimbi kanye nomphumela wesibuko ebusweni bezingxenye ezipuletiwe, okwenza ungqimba lwefilimu lube nezakhiwo ezinhle kakhulu zokuthiba ezintweni zefilimu, nokuhlinzeka ngokuvikela okuhle kakhulu kwe-electromagnetic kanye nemiphumela yokuqhuba.
