Vacuum coating inyanzvi umo zvinhu zvakatetepa-firimu zvinogadzirwa nenzira dzemuviri.Maatomu echinhu chiri mukamuri yevacuum anopatsanurwa kubva kune chinodziya uye anorova pamusoro pechinhu chinofanira kuiswa.Iyi tekinoroji yakatanga kushandiswa kugadzira lenzi dzemaziso, semarine telescope lenzi.Gare gare yakatambanudzirwa kune mamwe mafirimu anoshanda, rekodha aluminium plating, yekushongedza coating uye zvinhu pamusoro pekugadzirisa.Semuyenzaniso, bhegi rewachi rakaputirwa negoridhe rekutevedzera, uye banga remuchina rakaputirwa kuti richinje kutsvuka kwekugadzirisa uye kuoma.
Nhanganyaya:
Iyo firimu layer inogadzirirwa mune vacuum, kusanganisira plating crystalline simbi, semiconductor, insulator, uye mamwe ekutanga kana ecompound mafirimu.Kunyangwe kemikari vapor deposition inoshandisawo vacuum nzira senge kudzikiswa kudzvanywa, kuderera kana plasma, vacuum coating kazhinji inoreva kushandiswa kwemaitiro emuviri kuisa mafirimu matete.Kune matatu mafomu evacuum coating, anoti evaporation coating, sputtering coating uye ion plating.
Vacuum coating tekinoroji yakatanga kuoneka muma1930s, maindasitiri ekushandisa akatanga kuoneka muma1940 nema1950, uye kugadzirwa kwemaindasitiri kwakakura kwakatanga muma1980s.Yakave ichishandiswa zvakanyanya mumaindasitiri akadai semagetsi, aerospace, kurongedza, kushongedza, uye kupisa stamping.Vacuum coating inoreva kuiswa kweimwe simbi kana musanganiswa wesimbi pamusoro pechinhu (kazhinji chisiri chesimbi) muchimiro chechikamu chegasi munzvimbo yevacuum, inova maitiro ekuisa mhute.Nekuti iyo yekupfekedza kazhinji firimu resimbi, inonziwo vacuum metallization.Mupfungwa yakafara, vacuum coating inosanganisirawo vacuum deposition yeasiri-simbi anoshanda mafirimu akadai semapolymer pamusoro pesimbi kana zvisiri-simbi zvinhu.Pakati pezvinhu zvose zvinofanira kuputirwa, plastiki ndiyo yakawanda, inoteverwa nekuputira mapepa.Kuenzaniswa nesimbi, ceramics, huni nezvimwe zvinhu, mapurasitiki ane zvakanakira kubva kune akawanda masosi, kudzora kuri nyore kwekuita, uye nyore kugadzirisa.Naizvozvo, akasiyana mapurasitiki kana zvimwe zvinhu zvepolymer zvinoshandiswa seinjiniya yekushongedza zvimiro zvemidziyo uye inoshandiswa zvakanyanya mumotokari, midziyo yemumba, uye kushandiswa kwemazuva ese.Packaging, craft decoration uye mamwe maindasitiri minda.Nekudaro, zvinhu zvakawanda zvepurasitiki zvine hurema hwakadai sekuomarara kwepasi, kusakwana chitarisiko, uye kushomeka kwekushomeka.Semuenzaniso, firimu resimbi rakatetepa kwazvo rinogona kuiswa pamusoro pepurasitiki kuti ipe plastiki chimiro chesimbi yakajeka.Inogona kuwedzera zvakanyanya kupfekedzwa kwekupokana kwepamusoro pechinhu, uye kuwedzera zvakanyanya kushongedza uye chiyero chekushandisa kwepurasitiki.
Mabasa evacuum coating ane multifaceted, ayo anoonawo kuti nguva dzekushandisa dzayo dzakapfuma kwazvo.Kazhinji, iwo makuru mabasa evacuum coating anosanganisira kupa yakakwira dhigirii yesimbi kupenya uye girazi mhedzisiro kune pamusoro pezvikamu zvakapfava, zvichiita kuti firimu risave rive neakanakisa zvipingamupinyi zvivakwa pane iyo firimu zvinhu, uye kupa yakanakisa electromagnetic shielding uye conductive mhedzisiro.
