He mea maʻalahi ka hoʻohana ʻana, maʻalahi e hana, ʻo ia ka mea i hoʻohana nui ʻia i hoʻokahi ʻano kumu evaporation. Kapa ʻia ka poʻe i ka mea hana wela a i ʻole ka moku evaporation.
ʻO ka hoʻomaʻamaʻa ʻana i nā koi o ka mea pale i hoʻohana ʻia: ke kiʻekiʻe wela, resistivity, haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa i nā wela kiʻekiʻe, ʻaʻohe hopena kemika me ka mea membrane, ʻaʻole e hana i ka outgassing a me ka pollution. ʻO nā mea hoʻomehana kū'ē i koho nui ʻia mai nā metala refractory, e like me W, Mo, Ta a me nā mea ʻē aʻe a i ʻole ke koho ʻana i ka graphite kiʻekiʻe, ikaika kiʻekiʻe a i ʻole boron nitride synthetic conductive ceramics a me nā mea ʻē aʻe. I kekahi manawa, hiki no hoi ke koho Fe, Ni, Ni-Cr alloy a me Pt i evaporation kumu mea.
ʻOkoʻa ke kumu hoʻoheheʻe ʻana o nā mea maʻamau (e like me Ti, Mo, C, Ta, W, a me nā mea ʻē aʻe) o ka helu hoʻoheheʻe a me ke kaomi mahu a me ka pihi pili wela. Ma waena o lākou, lilo ka tungsten i mea palupalu i ka wā e wela ai i ka mahana evaporation ma muli o ka huahana junction wela. ʻO ka Molybdenum, ma ka ʻaoʻao ʻē aʻe, ʻokoʻa ka maʻemaʻe, me ka maʻemaʻe o kekahi, a ʻo kekahi ʻaʻole. Hoʻopili ʻo Tungsten me ka mahu wai e hana i ka pūhui oxygen maʻemaʻe WO3.
No laila, i ka wā e wela ai ka tungsten i ke koena o ka mahu wai, hoʻopau mau ʻia ka mea wela. I ka haʻahaʻa haʻahaʻa o ke koena kinoea, ʻaʻole nui ka pohō o ka waiwai, akā he haumia koʻikoʻi ia o ka membrane.
Pono ka hoʻohana ʻana i nā kumu filamentary i ka pulu ʻana o ka uea wela ma ka mea membrane. No ka laʻana, piʻi koke ka wela uea wela, ʻaʻole maʻalahi ka hoʻoheheʻe ʻana i nā mea membrane āpau a ʻaʻole lawa ka uea wela. ʻO ka hopena, hāʻule paha ke kiʻi i hoʻoheheʻe ʻole ʻia mai ka hīnaʻi uea. I ka manawa like, ʻoi aku ka wikiwiki o ka piʻi ʻana o ka mahana e hoʻokuʻu koke ʻia ka mea membrane i loko o ke kinoea, ka hopena i nā ʻōpū a i ʻole ka splashing, ʻo ka hopena e hana i ke kūkulu ʻana i nā kulu liʻiliʻi e pili ana i ka substrate. No laila, pono e hoʻohana ʻia nā puna filament me ka mālama ʻana i ka mahana.
ʻO ka hemahema nui o nā hīnaʻi uea, conical coils a spiral coils ʻo ia ka liʻiliʻi o nā mea kākoʻo kiʻiʻoniʻoni, a ʻo kēia kumu ke kumu e piʻi ai ka mahana o ka uea wela e like me ka emi ʻana o ka nui o nā mea kiʻiʻoniʻoni ma hope o ka hoʻoheheʻe ʻia ʻana o ka mea kiʻiʻoniʻoni, no laila e piʻi aʻe ka helu evaporation. He pilikia nō hoʻi kēia e ʻike ʻia no ke kaʻina hana kiʻiʻoniʻoni e pono ai ka hoʻomalu pono ʻana i ka helu evaporation.
(2) ʻO ke kumu hana a me ke ʻano o ka hoʻohana ʻana
Kū'ē mehana evaporation kumu, i ka mea, he kū'ē heater ka mea i ka hoʻohana 'ana i ka wela generator a evaporation moku pololei energized, no laila, i ka manawa ma o ka nui helu o Joule wela a loaʻa kiʻekiʻe wela e hehee ai metala film mea, no laila, i kona evaporation o ke ano o ka evaporation kumu.
