Resistance heat evaporation sosi chimiro chiri nyore, chiri nyore kushandisa, chiri nyore kugadzira, ndiyo inonyanya kushandiswa imwe mhando ye evaporation sosi. Vanhu vanowanzonzi heat generator kana evaporation boat.
Kupisa zvinodikanwa zvechinhu chinopikisa chinoshandiswa ndechekuti: tembiricha yakakwira, resistivity, yakaderera mhute kudzvanywa pakupisa kwakanyanya, hapana kemikari inopindirana neye membrane zvinhu, haiburitse kubuda uye kusvibiswa. Yakasarudzwa yekudzivirira kudziyisa zvinhu kunyanya kubva kune refractory simbi, senge W, Mo, Ta uye zvimwe zvinhu kana kusarudzwa kwepamusoro-kuchena, yakakwirira-simba graphite kana boron nitride synthetic conductive ceramics nezvimwe zvinhu. Dzimwe nguva, inogona zvakare kusarudza Fe, Ni, Ni-Cr alloy uye Pt senge evaporation sosi zvinhu.
Yakasiyana-siyana yekudzivirira kupisa evaporation sosi yezvinhu zvakajairika (seTi, Mo, C, Ta, W, nezvimwewo) yenzvimbo yekunyungudika uye mhute yekumanikidza uye tembiricha yehukama curve zvakasiyana. Pakati pavo, tungsten inova brittle kana ichipisa kune tembiricha yekubuda kwemhepo nekuda kwechigadzirwa chekudziya chinopisa. Molybdenum, kune rumwe rutivi, inosiyana mukuchena, vamwe vachiva brittle uye vamwe kwete. Tungsten inopindirana nemhute yemvura kuti igadzire musanganiswa weokisijeni weWO3.
Naizvozvo, kana tungsten ichipiswa mumhepo yakasara yemvura, iyo inopisa zvinhu inoramba ichipera. Kana iyo yakasara gasi pressure yakaderera, hapana kurasikirwa kwezvinhu zvakawanda, asi kusvibiswa kwakakomba kwe membrane.
Iko kushandiswa kwemafilamentary sources kunofanirwa kutarisisa kunyorova kwewaya inopisa pane membrane zvinhu. Semuyenzaniso, kupisa waya tembiricha inokwira nekukasira, iyo membrane zvinhu hazvisi nyore kunyungudutsa zvese zve membrane zvinhu uye inopisa waya wetting haina kukwana. Somugumisiro, iyo firimu isina kunyungudutswa inogona kudonha kubva mudengu rewaya. Panguva imwecheteyo, kukwira kwekushisa kwakanyanya kukurumidza kuchaitawo kuti membrane zvinhu mugasi iburitswe nekukurumidza, zvichikonzera mabhuru kana kupfachuka, mhedzisiro ichaita kuti kuumbwa kwemadonhwe madiki kunamatire kune substrate. Nokudaro, filament sources inofanira kushandiswa nekutonga kwekushisa.
Kunyanya kusakosha kwemabhasikiti ewaya, conical coils kana spiral coils ndeyekuti huwandu hwekutsigira firimu zvinhu hudiki, uye sosi iyi ichaita kuti tembiricha yewaya inopisa ikwire sezvo huwandu hwezvinhu zvemufirimu hunodzikira mushure mekunge zvinhu zvemufirimu zvanyungudika, nokudaro zvichikonzera kuwanda kweiyo evaporation. Iri zvakare idambudziko rinofanirwa kucherechedzwa kune iyo firimu yekugadzira iyo inoda kudzora kwakasimba kweiyo evaporation rate.
(2) The kushanda musimboti uye chimiro chimiro uye kushandisa hunhu
Resistance kudziyisa evaporation tsime, chaizvoizvo, ndiko kuramba hita ndiko kushandiswa kupisa jenareta kana evaporation chikepe zvakananga simba, kuitira kuti ikozvino kuburikidza nenhamba huru Joule kupisa uye kuwana tembiricha kunyungudutsa simbi firimu zvinhu, kuti ayo evaporation yemhando evaporation tsime.
