Qhov sib txawv tseem ceeb ntawm solidus thiab liquidus yog qhov kub ntawm solidus ntsuas qhov ntsuas kub ntawm cov khoom ua kom tiav, whereas liquidus kub ntsuas qhov kub ntawm cov khoom ua kom tiav.
Lub sij hawm solidus yog hais txog qhov chaw ntawm qhov kub thiab txias hauv qab no uas muaj qee yam khoom muaj zog. Liquidus yog qhov chaw ntawm qhov kub thiab txias saum toj no uas muaj qee yam khoom muaj nyob hauv cov kua.
Dab tsi yog Solidus?
Lub sij hawm solidus yog hais txog qhov chaw ntawm qhov kub thiab txias hauv qab no uas muaj qee yam khoom muaj nyob hauv cov khoom tiav. Hauv lwm lo lus, ib qho solidus yog qhov kub thiab txias uas cov khoom tshwm sim hauv cov qauv crystallized. Ib qho chaw yog ib txheej ntawm tag nrho cov ntsiab lus uas nws qhov chaw txaus siab lossis txiav txim siab ib lossis ntau qhov xwm txheej. Qhov chaw ntawm qhov kub thiab txias yog qhov nkhaus ntawm daim duab qhia theem. Feem ntau, solidus kub yog abbreviated li Ts los yog Tsol. Qhov ntsuas kub no qhia txog qhov ntsuas kub hauv qab no uas cov khoom tshwm sim hauv lub xeev muaj zog tag nrho thiab kuj yog qhov ntsuas kub tsawg kawg nkaus uas cov yaj tuaj yeem ua ke nrog cov muaju hauv cov thermodynamic sib npaug. Lo lus no tseem ceeb heev nyob rau hauv ntau yam xws li chemistry, material science, thiab physics. Ntawm lwm cov ntaub ntawv, hlau alloys, ceramics, ntuj pob zeb, thiab minerals tuaj yeem muab ua piv txwv rau solidus.
Lub solidus nyhav kom ntsuas qhov kub ntawm qhov uas lub melting ntawm ib yam khoom pib. Txawm li cas los xij, nyob rau lub sijhawm no, cov khoom yuav lossis tsis tuaj yeem yaj tag. Qhov no txhais tau tias lub solidus tsis yog ib txwm lub melting point ntawm cov khoom. Qhov no tuaj yeem siv los ua qhov sib txawv ntawm cov kua dej.
Lub solidus yeej ib txwm tsawg dua los yog sib npaug rau cov kua. Txawm li cas los xij, lawv yuav tsis coincide. Peb siv lo lus "freezing range" los qhia qhov sib txawv ntawm solidus thiab liquidus. Nyob rau hauv qhov sib txawv no, cov khoom zoo sib xws nyob rau hauv nws cov khoom thiab cov theem ua kua thiab tej zaum yuav zoo li slurry.
Ntxiv mus, nyob rau hauv eutectic mixs, solidus thiab liquidus kub coincide ntawm lub eutectic point. Nyob rau lub sijhawm no, cov khoom siv melts congruently.
Liquidus yog dab tsi?
Liquidus yog qhov chaw ntawm qhov kub thiab txias saum toj no uas muaj qee yam khoom muaj nyob hauv cov kua. Cov kua dej kub yog luv li TL los yog Tliq Nws yog qhov kub siab tshaj plaws ntawm cov muaju zoo sib xws nrog cov yaj hauv thermodynamic equilibrium. Feem ntau, cov kua dej muaj txiaj ntsig zoo rau cov khoom tsis huv, suav nrog iav, hlau, thiab pob zeb.
Thaum xav txog qhov kub siab tshaj li cov kua dej kub, cov khoom siv zoo li homogenous thiab kua ntawm qhov sib npaug. Hauv qab no qhov kub thiab txias qhov chaw, cov khoom nyhav tsim ntau thiab ntau muaju nyob rau hauv lub yaj, nyob ntawm seb qhov xwm ntawm cov khoom. Txawm li cas los xij, raws li lwm txoj hauv kev, peb tuaj yeem tau txais cov iav homogenous los ntawm cov cua txias txaus txaus. Qhov no tshwm sim los ntawm kinetic inhibition ntawm cov txheej txheem crystallization.
Hauv cov ntsiab lus ntshiab thiab cov khoom sib txuas xws li tooj liab thiab dej ntshiab, cov kua dej thiab cov solidus zoo li sib npaug ntawm qhov kub thiab txias. Hauv cov xwm txheej zoo li no, peb tuaj yeem siv lo lus "melting point". Txawm li cas los xij, rau cov khoom tsis huv xws li zib ntab, alloys, thiab lwm yam., peb tuaj yeem pom qhov nthuav dav ntawm melting point rau hauv lub sijhawm melting.
Qhov txawv ntawm Solidus thiab Liquidus yog dab tsi?
Lo lus solidus yog hais txog qhov chaw ntawm qhov kub thiab txias hauv qab no uas muaj qee yam khoom muaj nyob hauv cov khoom tiav. Liquidus yog qhov chaw ntawm qhov kub thiab txias saum toj no uas muaj qee yam khoom muaj nyob hauv cov kua. Qhov tseem ceeb sib txawv ntawm solidus thiab liquidus yog tias solidus kub quantifies qhov kub ntawm qhov uas cov khoom yuav solidified kiag li, whereas liquidus kub quantifies qhov kub ntawm cov tshuaj yuav ua tiav liquified.
Cov lus hauv qab no qhia txog qhov sib txawv ntawm solidus thiab liquidus.
Summary – Solidus vs Liquidus
Cov ntsiab lus solidus thiab liquidus muaj txiaj ntsig hauv ntau yam sib txawv, suav nrog chemistry, khoom siv science, thiab physics. Qhov sib txawv tseem ceeb ntawm solidus thiab liquidus yog tias solidus kub quantifies qhov kub ntawm cov khoom ua tiav solidified, whereas liquidus kub quantifies qhov kub ntawm cov khoom yuav ua tiav liquified.
