Isakhiwo somthombo we-resistance heat evaporation silula, kulula ukusisebenzisa, kulula ukusenza, siwumthombo wokuhwamuka osetshenziswa kakhulu. Abantu bavame ukubizwa ngokuthi i-heat generator noma isikebhe sokuhwamuka.
Ukushisa izidingo zezinto zokumelana ezisetshenziswayo yilezi: izinga lokushisa eliphezulu, ukumelana nokushisa, ukucindezela komhwamuko ophansi emazingeni okushisa aphezulu, akukho ukusabela kwamakhemikhali nge-membrane material, akukhiqizi ukuphuma nokungcola. Izinto zokushisa ezikhethiwe ezikhethiwe ikakhulukazi ezivela ezinsimbi eziphikisayo, njenge-W, Mo, Ta nezinye izinto noma ukukhethwa kokuhlanzeka okuphezulu, i-graphite yamandla aphezulu noma i-boron nitride synthetic conductive ceramics nezinye izinto. Kwesinye isikhathi, ingaphinda ikhethe i-Fe, i-Ni, i-Ni-Cr ingxubevange kanye ne-Pt njengempahla yomthombo wokuhwamuka.
Umthombo ohlukahlukene wokushisisa wokushisisa ohwamukayo wezinto ezijwayelekile (ezifana no-Ti, Mo, C, Ta, W, njll.) wendawo yokuncibilika kanye nomfutho womhwamuko kanye nejika lobudlelwano bezinga lokushisa kwehlukile. Phakathi kwazo, i-tungsten iba brittle uma ishiselwa kuzinga lokushisa lokuhwamuka ngenxa yomkhiqizo ohlanganisa ukufudumeza. I-molybdenum, ngakolunye uhlangothi, iyahlukahluka ngobumsulwa, kanti eminye iba brittle kanti eminye ayibi. I-Tungsten isabela nomhwamuko wakhe inhlanganisela yomoya-mpilo oguquguqukayo i-WO3.
Ngakho-ke, lapho i-tungsten ishiswa kumhwamuko wamanzi osele, izinto ezishisayo zincipha ngokuqhubekayo. Uma umfutho wegesi osele uphansi, akukho ukulahlekelwa okuningi kwezinto ezibonakalayo, kodwa kuwukungcoliswa okukhulu kolwelwesi.
Ukusetshenziswa kwemithombo ye-filamentary kufanele kunake ukumanziswa kocingo olushisayo ku-membrane material. Isibonelo, ukushisa kwentambo eshisayo kukhuphuka ngokushesha kakhulu, i-membrane impahla akulula ukuncibilikisa ngokushesha yonke impahla ye-membrane kanye nokumanzisa ucingo olushisayo akwanele. Ngenxa yalokho, ifilimu engancibilikisiwe ingase iwele kubhasikidi wocingo. Ngesikhathi esifanayo, ukukhuphuka kwezinga lokushisa kushesha kakhulu kuzophinde kubangele ulwelwesi olusegesini olukhishwe ngokushesha, okuholela kumabhamuza noma ukuchaphaza, umphumela uzokwenza ukwakheka kwamaconsi amancane anamathele ku-substrate. Ngakho-ke, imithombo ye-filament kufanele isetshenziswe ngokulawula izinga lokushisa.
Ububi obukhulu bobhasikidi bezintambo, amakhoyili ayikhoyili noma amakhoyili asongekile ukuthi inani lezinto zefilimu ezisekelayo lincane kakhulu, futhi lo mthombo uzobangela ukuthi izinga lokushisa locingo olushisayo likhuphuke njengoba inani lefilimu lehla ngemva kokuba impahla yefilimu ihwamukile, ngaleyo ndlela kubangele izinga lokuhwamuka likhuphuke. Lokhu futhi kuyinkinga okufanele kuqashelwe ngenqubo yokwenza ifilimu edinga ukulawulwa okuqinile kwezinga lokuhwamuka.
(2) Umgomo wokusebenza kanye nesakhiwo ukuma kanye nesici sokusebenzisa
Ukumelana Ukushisa Umthombo ukuhwamuka, eqinisweni, kuyinto ukumelana heater kuba ukusetshenziswa generator ukushisa noma ukuhwamuka isikebhe ngqo amandla, ukuze wamanje ngokusebenzisa inombolo enkulu Joule ukushisa futhi uthole izinga lokushisa eliphezulu ukuncibilika metal ifilimu impahla, ukuze ukuhwamuka yayo uhlobo umthombo ukuhwamuka.
