Cordierite mullite cib muaj qhov zoo ntawm tiv lub pob zeb kub. Cov khoom no yog ua los ntawm cordierite thiab zoo Mullite nrog zoo thermal poob siab. Nws yog nias los ntawm kev kub siab, thiab sintered los ntawm lub tuam txhab tshwj xeeb sijhawm tom qab 1000 degrees qhov kub thiab txias.
Cordierite mullite cib yog dab tsi?
Cordierite mullite cib tseem hu ua mullite cordierite cib. Cordierite thiab mullite muaj lawv tus kheej cov yam ntxwv. Txhawm rau txhawm rau txhim kho kev siv, ob hom cordierite tau sib koom ua ke thiab tsim tawm los ntawm ntau txoj kev sim kev txhim kho. Cov khoom daws cov teeb meem ntawm cov tawv thiab tsis tshua muaj load ntawm cordierite, thiab txhim kho lub thermal poob siab ua hauj lwm ntawm mullite. Cordierite mullite cib yog tsim ntawm mullite, andalusite, thiab Plate corundum thiab cordierite yog cov khoom siv tseem ceeb, ntxiv los ntawm ultra-nplua hmoov txhawb cov nplai, tom qab sib xyaw, molding, ziab, thiab kub kub ua haujlwm. Vim tias qhov hluav taws kub ntawm cov cordierite yog qhov nqaim heev, thiab qhov cub hluav taws kub yog qhov tseem ceeb heev, mullite cordierite cib npaj los ntawm gongzhi tsis tsuas yog muaj cov ua haujlwm thermal shock tsis kam, tab sis kuj muaj qhov kub siab ua hauj (1100 ℃ dej txias ≥ 100 lub sij hawm, tsis muaj qhov sib tsoo), tab sis kuj muaj qhov kub thiab txias Nws yog qhov tsim nyog rau kev lag luam ceramic tsheb saum npoo, phoov thawb phaj, roller kiln gasket, ceramic sagger thiab kub cua ceramic hlawv roj.
Taw qhia ntawm cov ntaub ntawv raw
Cordierite
Cordierite yog ib hom silicate ntxhia nrog cov tshuaj lom neeg hauv 2H0 • 2a12035s102. Nws yog dav siv vim nws qhov tsawg coefficient ntawm thermal expansion, zoo heev thermal stability thiab zoo thermal poob siab tsis kam. Feem ntau siv los ua cov ntaub ntawv kub siab, nws yog dav siv hauv cov khoom siv hauv tsheb, cov roj av tsheb, cov tshuaj tiv thaiv tshav kub, cov ntaub ntawv hloov cua sov, cov ntaub ntawv ntim khoom hluav taws xob, ua npuas ncauj ceramics, luam tawm cov laug cam, thiab qee qhov chaw txias thiab kub hloov chaw, xws li ceramic cov khoom ua cua sov, qhov cub tawg kub, lub qhov cub, lub teeb tawg, lub pob zeb cib, thiab lwm yam.
Cordierite ntau lawm txheej txheem
Cordierite yog ib hom khoom lag luam nrog kev ua haujlwm zoo thaum tshav kub. Nws yog feem ntau siv los tsim cov khoom lag luam nrog cov ntsiab lus siab ntawm cordierite (mg013,8%, 120334, 81i0251.4%). Cordierite refractories muaj cov cuab yeej siab zog thiab cov coefficient ntawm thermal nthuav dav. Lub flexural muaj zog ntawm cordierite refractories tuaj yeem ncav cuag 95 Pa. Cov coefficient ntawm o yog 2.0 × 10-6 ℃ - 1 hauv qhov ntsuas ntawm 20-800 ℃. Nws yog tsuas yog siv rau pliaj phaj, pliaj phaj, phaj pib, perforated phaj, thawb phaj thiab txhawb cib hauv Taozi kev lag luam. Talc-a1203 feem ntau yog siv.
Vim tias cov nplai ntawm qhov tsim qhov kub ntawm qhov cordierite yog tsawg heev, cov undercired cordierite tsis tuaj yeem tau txais, thiab dhau ntawm cordierite yuav muab faib ua mullite thiab iav. Yog li, kev xaiv cov siab alumina cordierite cov khoom lag luam tsis tuaj yeem tsuas yog nthuav tawm qhov kub thiab txias ntawm qhov tsim kom muaj cordierite, tab sis kuj tseem zam kev sib txawv ntawm cordierite ntawm qhov kub, thiab txhim kho qhov zoo ntawm cordierite. High alumina cordierite cov khoom muaj cov haujlwm zoo dua li cov av nplaum cordierite khoom. Raws li cov yam ntxwv ntawm kev tsim kho cordierite, nws tsis muaj peev xwm ua kom sov siab sai sai hauv qhov teev ntawm 9001200 ℃ txhawm rau kom tso lub cev ntsuab
Sab hauv crystallization dej thiab txhawb nqa ntawm talc sib txawv. Nws yog theem ntawm cordierite tsim los ntawm 1200 ℃ txog 1300 ℃. Hauv qhov ntsuas kub no, tus nqi cua sov yuav tsum qeeb thiab ruaj khov
