Qhov sib txawv tseem ceeb ntawm crucible thiab evaporating phaj yog crucible yog lub thawv uas siv rau melting ntawm hlau los yog raug cov khoom mus rau qhov kub thiab txias whereas evaporating phaj yog ib lub thawv siv rau evaporation ntawm kev daws thiab supernatant kua.
Crucible thiab evaporating phaj yog qhov tseem ceeb hauv chav kuaj iav uas feem ntau tuaj rau hauv qhov kub thiab txias. Cov thawv no zoo ib yam li cov duab tab sis txawv ntawm ib leeg raws li lawv qhov muaj pes tsawg leeg thiab daim ntawv thov.
Crucible yog dab tsi?
Crucible yog lub thawv ua los ntawm cov ceramic lossis hlau, thiab nws muaj txiaj ntsig zoo rau melting lossis cua sov cov khoom rau qhov kub thiab txias. Keeb kwm, cov thawv no tau tsim los ntawm cov av nplaum es tsis txhob siv cov ceramic, thiab lawv tuaj yeem ua los ntawm cov khoom siv uas tsis tshua muaj zog thiab tuaj yeem tiv taus qhov kub thiab txias.
Daim duab 01: Lub Ntiaj Teb Crucible
Ntxiv mus, peb tuaj yeem siv cov khob iav no hauv chav kuaj kom muaj cov tshuaj sib txuas uas tau ua kom sov rau qhov kub siab heev. Muaj ntau qhov ntau thiab tsawg ntawm crucibles muaj muag, thiab feem ntau cov thawv no tuaj nrog lub hau uas haum rau qhov loj ntawm lub crucible. Peb tuaj yeem ua kom sov lub crucible tshaj nplaim taws. Feem ntau, lub thawv no yuav tsum tau khaws cia rau ntawm daim duab peb sab pipeclay qhov twg cov nplaim tuaj yeem hloov kho rau qhov chaw ntawm daim duab peb sab.
Feem ntau, cov chaw tsim khoom siv cov khoom siv kub-resistant xws li cov plooj (porcelain, alumina) thiab cov hlau tsis muaj zog los ua cov crucibles. Yav dhau los, tib neeg siv platinum rau qhov kev tsim khoom no kom nws tuaj yeem tiv taus qhov kub thiab txias. Niaj hnub no, peb siv ceramics xws li alumina, zirconia, thiab magnesia vim platinum kim heev.
Tsis tas li ntawd, lub hau feem ntau ua rau poob qis rau lub crucible, uas yuav pab tau kom cov gases khiav tawm cov qauv hauv lub crucible. Muaj ntau qhov ntau thiab tsawg thiab cov duab ntawm crucibles muaj muag.
Yuav ua li cas evaporating tais?
Ib lub tais evaporating yog lub thawv kuaj uas muaj txiaj ntsig zoo hauv cov evaporation ntawm cov tshuaj thiab cov kua dej supernatant. Qee zaum, cov qauv hauv cov tais no yog rhuab mus rau nws qhov melting point. Cov thawv no muaj txiaj ntsig zoo rau cov evaporation ntawm cov kuab tshuaj ntau dhau (xws li dej) kom tau txais cov tshuaj concentrated lossis qee zaum cov kua dej los ntawm cov tshuaj.
Daim duab 02: Ntau qhov sib txawv ntawm evaporating tais
Feem ntau, cov tais diav uas ua los ntawm cov plooj (porcelain) lossis borosilicate iav uas tuaj yeem tiv taus qhov kub thiab txias. Muaj cov iav ntiav evaporating tais diav uas feem ntau hu ua tsom iav. Cov iav no tsis tuaj yeem siv rau cov ntawv thov kub heev.
Feem ntau, lub peev xwm ntawm lub tais evaporating yog nyob rau hauv thaj tsam ntawm 3 - 10 mL. Txawm li cas los xij, tuaj yeem muaj qee cov tais diav loj, xws li. 100ml, nyob ntawm daim ntawv thov. Cov tais diav loj no nyob rau hauv cov duab sib txawv thiab muaj ntau hemispherical. Feem ntau, lub evaporator yog qhov muaj txiaj ntsig zoo rau kev txheeb xyuas qhov ntau.
Qhov txawv ntawm Crucible thiab Evaporating phaj yog dab tsi?
Crucible thiab evaporating phaj tshwm nyob rau hauv cov duab zoo sib xws tab sis txawv ntawm ib leeg raws li muaj pes tsawg leeg thiab daim ntawv thov. Qhov sib txawv tseem ceeb ntawm crucible thiab evaporating phaj yog crucible yog ib lub thawv uas siv rau melting ntawm hlau los yog tej yam khoom mus rau qhov kub thiab txias, whereas evaporating phaj yog ib lub thawv siv rau evaporation ntawm kev daws thiab supernatant kua.
Hauv qab no yog ib daim ntawv teev qhov sib txawv ntawm crucible thiab evaporating phaj nyob rau hauv daim ntawv tabular.
Summary – Crucible vs Evaporating Dish
Crucible thiab evaporating phaj yog qhov tseem ceeb hauv chav kuaj iav uas feem ntau tuaj rau hauv qhov kub thiab txias. Lub crucible yog ib lub thawv uas siv rau lub melting ntawm hlau los yog tej yam khoom mus rau qhov kub thiab txias, thaum lub evaporating tais yog ib lub thawv uas siv rau evaporation ntawm kev daws thiab supernatant kua. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm crucible thiab evaporating phaj.
