Kiʻiʻoniʻoni Layer Evaporation Mahana a me Vapor Pressure

Hiki i ka papa kiʻiʻoniʻoni ke hoʻolilo i nā ʻāpana membrane i ke ʻano o nā mana (a i ʻole nā ​​mole) i loko o ka lumi hau. Ma lalo o ka wela kiʻekiʻe o ke kumu hoʻoheheʻe, loaʻa i nā atom a i ʻole nā ​​molekole ma luna o ka ʻili o ka membrane ka lawa o ka ikehu e lanakila ai i ka ʻili o ka ʻili a e mahuka mai ka ʻili. Aia kēia mau ʻātoma a i ʻole nā ​​molekole i loko o kahi ʻano kinoea i loko o kahi hakahaka, ie. nā mea metala a i ʻole nā ​​mea hao ʻole.

I loko o kahi kaʻawale, hiki ke hoʻomaikaʻi ʻia nā kaʻina hana hoʻomehana a me ka evaporation o nā mea membrane. Hoʻemi ke kaiapuni vacuum i ka hopena o ke kaomi ea i ke kaʻina evaporation, e maʻalahi ka hana evaporation. Ma ke kaomi o ka lewa, pono e hoʻokau ʻia ka mea i ke kaomi nui e lanakila ai i ke kūʻē ʻana o ke kinoea, ʻoiai i loko o kahi ʻawaʻawa, ua hoʻemi nui ʻia kēia kūpaʻa, e maʻalahi ka evaporate. Ma ke kaʻina hana hoʻoheheʻe ʻana, ʻo ka mahana hoʻoheheʻe a me ke kaomi mahu o ka mea kumu hoʻoheheʻe he mea koʻikoʻi i ke koho ʻana i ka mea kumu evaporation. No ka uhi ʻana o Cd (Se, s), ʻo kona mahana evaporation ka mea maʻamau i ka 1000 ~ 2000 ℃, no laila pono ʻoe e koho i ke kumu evaporation me ka mahana evaporation kūpono. E like me ka alumini ma ka evaporation pressure evaporation wela o 2400 ℃, akā i loko o nā kūlana vacuum, e hāʻule nui ka mahana evaporation. ʻO kēia no ka mea ʻaʻohe molekele lewa i loko o ka ʻākea ʻana, i hiki ke maʻalahi i ka hoʻoheheʻe ʻia ʻana o nā ʻātoma alumina a i ʻole nā ​​molekole mai ka ʻili. He mea koʻikoʻi kēia hiʻohiʻona no ka uhi ʻana i ka evaporation vacuum. I loko o kahi lewa, e maʻalahi ka hoʻokō ʻana i ka evaporation o ka mea kiʻiʻoniʻoni, i hiki ke hana ʻia nā kiʻiʻoniʻoni lahilahi ma nā haʻahaʻa haʻahaʻa. ʻO kēia haʻahaʻa haʻahaʻa e hōʻemi ana i ka oxidization a me ka decomposition o ka mea, no laila e hāʻawi i ka hoʻomākaukau ʻana i nā kiʻiʻoniʻoni kiʻekiʻe.
I ka wā o ka uhi ʻia ʻana, ʻo ke kaomi ʻana o nā mahu o ka mea kiʻiʻoniʻoni i hoʻohālikelike ʻia i loko o kahi paʻa a i ʻole ka wai i kapa ʻia ʻo ke kaomi mahu saturation i kēlā mahana. Hōʻike kēia kaomi i ka equilibrium dynamic o ka evaporation a me ka condensation ma kahi mahana i hāʻawi ʻia. ʻO ka mea maʻamau, ʻoi aku ka haʻahaʻa o ka mahana ma nā ʻāpana ʻē aʻe o ke keʻena ʻeleʻele ma mua o ka mahana o ke kumu hoʻoheheʻe, kahi e maʻalahi ai ka hoʻoheheʻe ʻana i nā ʻātoma membrane a i ʻole nā ​​molekole e condense ma nā wahi ʻē aʻe o ke keʻena. I kēia hihia, inā ʻoi aku ka nui o ka hoʻoheheʻe ʻana ma mua o ka nui o ka condensation, a laila i ka equilibrium dynamic e hiki i ke kaomi mahu ka saturation kaomi. ʻO ia hoʻi, ma kēia ʻano, ua like ka helu o nā ʻātoma a i ʻole nā ​​molekole e hoʻoheheʻe ʻia me ka helu condensing, a hiki i ka equilibrium dynamic.
