Filimu Wosanjikiza Evaporation Kutentha ndi Kupanikizika kwa Nthunzi

Filimu wosanjikiza mu evaporation gwero la kutentha evaporation akhoza kupanga nembanemba particles mu mawonekedwe a atomu (kapena mamolekyu) mu mpweya gawo danga. Pansi pa kutentha kwakukulu kwa gwero la evaporation, ma atomu kapena mamolekyu omwe ali pamwamba pa nembanemba amapeza mphamvu zokwanira kuti athetse kugwedezeka kwapamtunda ndikuchoka pamwamba. Awa maatomu kapena mamolekyu amakhala nthunzi mu mkhalidwe mpweya mu vacuum, mwachitsanzo gasi gawo danga. zitsulo kapena zopanda zitsulo.

M'malo opanda vacuum, njira zotenthetsera ndi kutuluka kwa zinthu za membrane zimatha kuwongolera. Malo a vacuum amachepetsa mphamvu ya mumlengalenga pamayendedwe a nthunzi, kupangitsa kuti mpweya ukhale wosavuta kuchita. Pakuthamanga kwa mlengalenga, zinthuzo zimafunika kuti zikhale zovuta kwambiri kuti zigonjetse kukana kwa mpweya, pamene m'malo opanda mpweya, kukana kumeneku kumachepetsedwa kwambiri, zomwe zimapangitsa kuti zinthuzo zikhale zosavuta. Mu ndondomeko ❖ kuyanika evaporation, kutentha evaporation ndi nthunzi kuthamanga kwa evaporation gwero zakuthupi ndi chinthu chofunika posankha evaporation gwero zakuthupi. Pakuti Cd (Se, s) ❖ kuyanika, evaporation kutentha ake nthawi zambiri mu 1000 ~ 2000 ℃, choncho muyenera kusankha evaporation gwero zakuthupi ndi kutentha evaporation yoyenera. Monga aluminiyamu pamlengalenga kutentha kwa mpweya wa 2400 ℃, koma m'malo opanda mpweya, kutentha kwake kumatsika kwambiri. Izi zili choncho chifukwa palibe mamolekyu a mumlengalenga mu chotchinga cha vacuum, kotero kuti maatomu a aluminiyamu kapena mamolekyu amatha kutuluka mosavuta kuchokera pamwamba. Chodabwitsa ichi ndi chofunikira kwambiri pakupaka vacuum evaporation. M'malo opanda vacuum, kutuluka kwa filimuyo kumakhala kosavuta kuchita, kotero kuti mafilimu opyapyala amatha kupangidwa potentha kwambiri. Kutentha kwapansi kumeneku kumachepetsa makutidwe ndi okosijeni ndi kuwonongeka kwa zinthu, motero kumathandizira kukonzekera mafilimu apamwamba kwambiri.
Pa ❖ kuyanika vakuyumu, kupanikizika komwe nthunzi za filimuyo zimafanana mu olimba kapena madzi kumatchedwa machulukitsidwe nthunzi kuthamanga pa kutentha. Kuthamanga uku kumasonyeza kufanana kwamphamvu kwa mpweya ndi condensation pa kutentha komwe kumaperekedwa. Kawirikawiri, kutentha m'madera ena a chipinda chosungiramo mpweya kumakhala kotsika kwambiri kusiyana ndi kutentha kwa gwero la evaporation, zomwe zimapangitsa kuti ma atomu a nembanemba kapena mamolekyu asungunuke mosavuta m'madera ena a chipinda. Pamenepa, ngati mlingo wa evaporation ndi waukulu kuposa mlingo wa condensation, ndiye mu dynamic equilibrium nthunzi kuthamanga kufika machulukitsidwe nthunzi kuthamanga. Ndiko kuti, pamenepa, chiwerengero cha ma atomu kapena mamolekyu omwe akutuluka nthunzi ndi ofanana ndi chiwerengero cha condensing, ndipo chiwerengero cha mphamvu chimafikira.
