Khoom ntawm ladle breathable cib

cov ladle cua-permeable cib tuaj yeem ntxuav cov pa roj thiab cov khoom tsis huv hauv cov hlau molten los ntawm tshuab argon hauv qab, thiab tuaj yeem ua tiav lub hom phiaj ntawm kev ua kom cov hlau sib xyaw ua ke thiab qhov kub thiab txias, thiab nws qhov tseem ceeb yog qhov pom tseeb. Cov khoom siv ntawm cov pob zeb ua pa ua pa tau txiav txim siab nws cov yam ntxwv. Txhawm rau kom ua tiav lub hom phiaj ntawm tshuab cov argon hauv qab ntawm cov pob zeb ua pa, cov cib ua pa tau tsim kom muaj cua sov ruaj khov, tiv taus yaig, tiv thaiv yaig, tiv taus permeability, ua haujlwm nyab xeeb, thiab huab cua permeability. Zoo, tsawg nkag mus ntawm cov hlau yaj, thiab lwm yam.

(Duab) Impermeable Breathable Cib

Magnesium: Cov khoom siv magnesium hais txog cov khoom siv hluav taws xob nrog cov ntsiab lus MgO ntau dua 80%. Cov khoom lag luam Magnesium feem ntau yog tsim los ntawm sintering. Qhov ntsuas kub yog feem ntau ntawm 1500 txog 1800 ° C. Nws muaj qhov ua kom rov zoo dua qub thiab muaj zog tiv taus slag yaig. , Tsis ua paug hlau yaj, thiab lwm yam; tab sis qhov coefficient ntawm kev nthuav dav cua sov yog qhov loj, thiab cov cua sov tsis kam ua haujlwm tsis zoo, ua rau cov khoom siv tev tawm yooj yim, uas txo qis kev pabcuam lub neej.

Magnesium chromium: Cov khoom siv magnesium chromium yog cov khoom siv hluav taws xob nrog MgO thiab Cr2O3 ua cov khoom tseem ceeb. Nws tsis tsuas yog muaj kev tiv thaiv zoo rau alkali slag thaum nws los sib cuag nrog cov hlau molten, tab sis kuj muaj cov yam ntxwv ntawm cov khoom sib nqus theem, uas tuaj yeem ua tau zoo heev tiv thaiv kev nkag mus ntawm cov hlau yaj. Txawm li cas los xij, thaum nws tau npaj thiab siv nyob rau hauv qhov kub thiab txias, nws yuav tsim teeb meem hexavalent chromium sib xyaw thiab ua rau muaj kuab paug ib puag ncig. Raws li lub tebchaws cov xwm txheej uas kev tiv thaiv ib puag ncig tau dhau los ua qhov tseem ceeb dua, cov khoom siv ntawm magnesia-chromium cov khoom yuav poob qis.

High-aluminium: High-aluminium cov ntaub ntawv xa mus rau cov khoom siv hluav taws xob nrog Al2O3 cov ntsiab lus ntau dua 48% txog 75%. Lawv muaj cov yam ntxwv ntawm qhov txias txias thiab kub zog, thermal poob siab tsis kam, thiab lub zog muaj zog siab, tab sis lawv muaj qhov tsis zoo permeability.

(Duab) Corundum Breathable Cib

Corundum: Cov khoom siv Corundum hais txog cov khoom siv hluav taws xob nrog Al2O3 cov ntsiab lus siab dua 90%. Cov khoom siv hluav taws xob uas nws lub hauv paus tseem ceeb yog α-Al₂O₃ (corundum). Ntxiv Cr2O3 rau cov khoom tuaj yeem tiv thaiv kev loj hlob ntau dhau ntawm alumina muaju, yog li txo qis kev nyuaj siab sab hauv ntawm cov nplais thiab txhim kho lub cev ntsuas ntawm cov khoom. Txawm li cas los xij, yog tias Cr2O3 tau ntxiv ntau dhau, qhov kev loj hlob ntawm corundum nplej yuav raug cuam tshuam loj heev, thiab lub cev lub cev ntawm cov khoom yuav raug txo. Ib qho ntxiv, los ntawm kev xav txog kev tiv thaiv ib puag ncig, qhia txog Cr2O3 yuav ua rau muaj kuab paug ib puag ncig, yog li qhia txog Cr2O3 yuav tsum tau ua tib zoo xav.
