Rutivi rwefirimu riri muchinhu chinobuda mvura kubva mumhepo chinodziya rinogona kuita kuti zvidimbu zvemembrane muchimiro chemaatomu (kana mamorekuru) zvipinde munzvimbo yegesi. Pasi pekupisa kwakanyanya kwechinhu chinobuda mvura kubva mumhepo, maatomu kana mamorekuru ari pamusoro pemembrane anowana simba rakakwana rekukunda kushushikana kwepamusoro uye kubuda mvura kubva pamusoro. Aya maatomu kana mamorekuru anobuda mvura aripo muchimiro chegasi muvacuum, kureva nzvimbo yegesi kubva muchikamu chesimbi.
Munzvimbo isina chinhu, maitiro ekupisa uye evaporation yezvinhu zve membrane anogona kuvandudzwa. Nzvimbo isina chinhu inoderedza simba rekumanikidzwa kwemhepo pakuita kwe evaporation, zvichiita kuti evaporation ive nyore kuita. Pakumanikidzwa kwemhepo, zvinhu zvinoda kumanikidzwa zvakanyanya kuti zvikunde resistance yegesi, nepo mu vacuum, resistance iyi inodzikira zvikuru, zvichiita kuti zvinhu zvive nyore kusvibiswa. Mukuita kwe evaporation coating, tembiricha ye evaporation uye evaporation pressure yezvinhu zve evaporation chinhu chakakosha pakusarudza evaporation source material. Kune Cd (Se, s) coating, evaporation tembiricha yayo inowanzo kuve mu 1000 ~ 2000 ℃, saka unofanirwa kusarudza evaporation source material ine evaporation tembiricha yakakodzera. Sezvakaita aruminiyamu pa evaporation pressure tembiricha ye 2400 ℃, asi mumamiriro e vacuum, evaporation tembiricha yayo ichaderera zvakanyanya. Izvi zvinodaro nekuti hapana ma molecule emumhepo mu vacuum blockage, kuitira kuti maatomu ealuminium kana mamorekuru agone kusvibiswa nyore nyore kubva pamusoro. Ichi chiitiko chakakosha che vacuum evaporation coating. Mumhepo isina chinhu, kupwanyika kwechinhu chiri mufirimu kunova nyore kuita, kuitira kuti mafirimu matete agone kuumbwa patembiricha yakaderera. Tembiricha yakaderera iyi inoderedza oxidization uye kuora kwechinhu chacho, nokudaro zvichibatsira mukugadzirira mafirimu emhando yepamusoro.
Munguva yekuputira vacuum, kumanikidzwa uko mhute yefirimu inoenzana muchinhu chakasimba kana mvura kunonzi kumanikidzwa kwemhute yemvura pakupisa ikoko. Kumanikidzwa uku kunoratidza kuenzana kwesimba remhute nekudzika kwemvura pakupisa kwakapihwa. Kazhinji, tembiricha mune dzimwe nzvimbo dzekamuri remhute yakaderera zvikuru pane tembiricha yetsime remhute, izvo zvinoita kuti zvive nyore kuti maatomu emudumbu kana mamorekuru abude mumhepo abude muzvimwe zvikamu zvekamuri. Muchiitiko ichi, kana mwero wekubuda kwemvura wakakura kupfuura mwero wekudzika kwemvura, saka mukuenzanisa kwesimba, kumanikidzwa kwemhute kuchasvika pakumanikidzwa kwemhute yemvura. Kureva kuti, muchiitiko ichi, huwandu hwemaatomu kana mamorekuru ari kubuda huenzana nenhamba iri kudzika, uye kuenzana kwesimba kunosvika.
