Tus ntooyog cov cuab yeej tseem ceeb hauv kev lag luam rau kev tuav tau melting thiab smelting txheej txheem. Nws yog lub thawv ntim uas tuaj yeem tiv thaiv kom muaj qhov kub thiab yog siv los tuav cov tshuaj thiab ua kom sov rau lawv cov po melting. Ntau hom crucibles tau siv nyob ntawm qhov uas muaj cov kev xav tau ntawm cov khoom tau melted lossis smelted. Hauv no blog ncej, peb yuav tshawb txog cov kev sib txawv thiab lawv cov kev siv.
1. Daim Crucible:
Siv ib qho qauv hlau ntoo thaum melting muaj zog alkaline xws li Naoh. Txawm li cas los xij, nws tsis tau siv dav vim muaj teeb meem xws li xeb yooj yim thiab oxidation. Nyob rau hauv feem ntau cov ntawv thov koom nrog alkaline cov ntaub ntawv, inert hlau cruciles nyob twj ywm xaiv qhov kev xaiv zoo.
2. Nrum Hlau Crucible:
Cam khwb cia hlau crucibles yog tsim los ntawm npua hlau thiab paub txog lawv lub siab. Nws yog siv los yaj ntau hlau alloys suav nrog txhuas, zinc, txhuas, tin thiab alloma alloys. Piv rau cov hlau ntoo, cam khwb cia hlau cruciles muaj ntau ruaj thiab tuaj yeem tiv taus qhov siab kub uas yuav tsum tau yaj cov alloys no.
3. Quartz Crucible:
Quartz crucibles feem ntau siv nyob rau hauv kev lag luam semiconduct thiab yog qhov tseem ceeb rau kev tsim cov khoom sib xyaw loj loj. Cov crucers no tuaj yeem tiv taus kub txog li 1650 degrees thiab muaj nyob rau hauv cov qauv ntshiab thiab opaque. Txhais tau tias yog cov txheej txheem Arttz Crucute tsim los ntawm Arc Txujcual, siv rau rub tawm rau rub tawm loj loj hla ib lub crystal silicon. Nws muaj qhov zoo ntawm cov siab purity, muaj zog kub, loj loj, siab thermal rwb thaiv tsev kev ua haujlwm, txuag hluav taws xob, thiab ruaj khov zoo. Txawm li cas los xij, kev saib xyuas yuav tsum tau noj raws li Quartz yog nkig thiab tuaj yeem tawg yooj yim.
4. Porcelain Crucible:
Ceramic crucailed yog nrov rau lawv cov tshuaj tiv thaiv thiab pheej yig. Txawm li cas los xij, nws tsis tuaj yeem siv rau yaj alkaline cov tshuaj xws li Naoh, NA2O2, NA2CO3, thiab lwm yam, vim tias lawv yuav hnov mob nrog plooj (porcelax thiab ua rau xeb. Tsis tas li ntawd, plooj (veecel) crucibles yuav tsum tsis txhob tuaj cuag tau nrog hydrofluoric acid. Lawv tsim nyog rau kev siv nyob rau ntawm qhov kub nyob ib ncig ntawm 1200 degrees.
5. Corundum Crucible:
Corundum Crucible yog heev haum rau melting kuaj uas siv tsis muaj zog alkaline cov tshuaj xws li anhydrous na 2 co 3 raws li flux. Txawm li cas los xij, lawv tsis haum rau melting kuaj siv cov tshuaj Alkaline uas muaj tseeb (xws li na2o2, Naoh) lossis acidic tshuaj (xws li k2s2o7) as fluxes.
6. Graphite Crucible:
Graphite cross yog dav siv nyob rau hauv cov hlau casting kev lag luam vim lawv zoo heev thermal conductivity thiab kub tsis kam. Lawv haum rau melting ntau cov hlau xws li tooj liab, kub, nyiaj thiab tooj dag.
7. Silicon Carbide Crucible:
Silicon carride crucai yog paub rau lawv cov siab thermal conductivity thiab zoo heev tshuaj lom neeg tiv thaiv. Lawv raug siv rau hauv cov txheej txheem melting thiab smelting nrog cov ntawv thov kub siab, xws li kev tsim cov ceramics thiab alloys.
Txhua hom crucible muaj nws tus kheej tshwj xeeb zoo thiab cov ntawv thov. Kev xaiv CleCible nyob ntawm yam xws li cov khoom tau melted lossis smelted, qhov xav tau ntau yam thiab nyiaj txiag. Txawm hais tias koj tau melting tooj liab, casting hlau, lossis smelting alloys, xaiv txoj cai crucible yog qhov tseem ceeb rau kev ua tiav thiab kev ua haujlwm tau zoo.
Hauv cov ntsiab lus, cruciles ua si ib lub luag haujlwm tseem ceeb hauv kev lag luam ntau yam kev sib koom tes nrog kev pom zoo thiab cov txheej txheem smelting. Nkag siab txog cov crucaily muaj ntau yam thiab lawv cov ntawv thov tshwj xeeb tuaj yeem pab cov lag luam tau txiav txim siab txog kev txiav txim siab uas tau ua kom tau raws li lawv cov kev xav tau. Seb nws yog cov hlau ci ntsa iab, nrum hlau crucible, quartz crucible, colelain crucible, txhua hom muaj nws tus kheej thiab cov kev txwv. Los ntawm kev xaiv cov crucible, cov lag luam tuaj yeem ua kom tiav lawv txoj haujlwm thiab ua kom muaj txiaj ntsig zoo.
