Cov yam ntxwv ntawm aluminium silicate refractory fiber 1

Hauv kev cob qhia uas tsis yog ferrous hlau casting, hom zoo, lub thawv hom tsis kam rauv yog dav siv los yaj hlau thiab cua sov & qhuav ntau yam ntaub ntawv. Lub zog siv los ntawm cov cuab yeej no suav nrog ntau feem ntawm lub zog siv los ntawm tag nrho kev lag luam. Yuav ua li cas thiaj li siv tau thiab txuag hluav taws xob yog ib qho ntawm cov teeb meem tseem ceeb uas cov lag luam lag luam yuav tsum tau daws sai sai. Feem ntau hais lus, kev siv lub zog txuag hluav taws xob yog yooj yim dua li tsim cov khoom siv hluav taws xob tshiab, thiab kev siv hluav taws xob rwb thaiv tsev yog ib qho ntawm cov cuab yeej txuag hluav taws xob uas yooj yim rau kev siv thiab tau siv dav. Ntawm ntau cov ntaub ntawv rwb thaiv tsev refractory, aluminium silicate refractory fiber ntau tau txais txiaj ntsig los ntawm tib neeg rau nws qhov kev ua tau zoo, thiab tau siv dav hauv ntau yam kev lag luam kilns.

Aluminium silicate refractory fiber yog ib yam tshiab ntawm refractory thiab thermal rwb thaiv tsev cov ntaub ntawv. Cov ntaub ntawv pov thawj qhia tau tias siv aluminium silicate refractory fiber ntau li refractory lossis rwb thaiv tsev cov khoom siv hluav taws xob tuaj yeem txuag tau ntau dua 20% ntawm lub zog, qee qhov txog 40%. Aluminium silicate refractory fiber muaj cov yam ntxwv hauv qab no.
(1) Kub kub kuj
Ib txwmaluminium silicate refractory fiber ntauyog ib hom amorphous fiber ntau ua los ntawm refractory av nplaum, bauxite los yog siab alumina raw cov ntaub ntawv los ntawm tshwj xeeb txias txoj kev nyob rau hauv lub melting xeev. Qhov kev pabcuam kub yog feem ntau qis dua 1000 ℃, thiab qee qhov tuaj yeem ncav cuag 1300 ℃. Qhov no yog vim qhov thermal conductivity thiab kub muaj peev xwm ntawm aluminium silicate refractory fiber nyob ze rau huab cua. Nws yog tsim los ntawm cov khoom fibers thiab huab cua, nrog ib tug porosity ntawm tshaj 90%. Vim tias qhov loj ntawm cov thermal conductivity tsawg cua ntim cov pores, qhov txuas txuas txuas ntxiv ntawm cov khoom molecules raug cuam tshuam, ua rau muaj kev kub ntxhov thiab kev ua haujlwm rwb thaiv tsev zoo.
Qhov teeb meem tom ntej no peb yuav txuas ntxiv qhia cov yam ntxwv ntawm aluminium silicate refractory fiber. Thov nyob twj ywm!
