Cov yam ntxwv ntawm txhuas silicate refractory fiber 1

Hauv cov chaw ua haujlwm casting hlau uas tsis yog ferrous, cov qhov dej, hom thawv tiv taus cua sov yog siv dav los yaj cov hlau thiab ua kom sov & qhuav ntau yam khoom siv. Lub zog siv los ntawm cov khoom siv no suav nrog feem ntau ntawm lub zog siv los ntawm tag nrho kev lag luam. Yuav ua li cas siv thiab txuag hluav taws xob kom raug yog ib qho teeb meem tseem ceeb uas kev lag luam xav tau daws sai sai. Feem ntau hais lus, kev siv cov kev ntsuas txuag hluav taws xob yooj yim dua li kev tsim cov peev txheej hluav taws xob tshiab, thiab cov thev naus laus zis rwb thaiv tsev yog ib qho ntawm cov thev naus laus zis txuag hluav taws xob uas yooj yim siv thiab tau siv dav. Ntawm ntau cov ntaub ntawv rwb thaiv tsev refractory, txhuas silicate refractory fiber tau raug suav los ntawm tib neeg rau nws qhov kev ua tau zoo tshwj xeeb, thiab siv dav hauv ntau lub cub tawg kev lag luam.

Aluminium silicate refractory fiber yog ib hom khoom siv refractory thiab thermal insulation tshiab. Cov ntaub ntawv qhia tau tias kev siv aluminium silicate refractory fiber ua refractory lossis insulation khoom ntawm lub cub tawg tuaj yeem txuag tau ntau dua 20% ntawm lub zog, qee qhov txog li 40%. Aluminium silicate refractory fiber muaj cov yam ntxwv hauv qab no.
(1) Kev kub siab tsis kam
Ib txwmtxhuas silicate refractory fiberyog ib hom amorphous fiber ua los ntawm cov av nplaum refractory, bauxite lossis cov khoom siv alumina siab los ntawm txoj kev txias tshwj xeeb hauv lub xeev yaj. Qhov kub ntawm kev pabcuam feem ntau yog qis dua 1000 ℃, thiab qee qhov tuaj yeem ncav cuag 1300 ℃. Qhov no yog vim tias cov thermal conductivity thiab lub peev xwm cua sov ntawm cov txhuas silicate refractory fiber ze rau huab cua. Nws yog tsim los ntawm cov khoom siv fiber thiab huab cua, nrog rau porosity ntawm ntau dua 90%. Vim muaj ntau cov cua sov conductivity qis uas puv cov qhov hws, cov qauv network tas mus li ntawm cov khoom siv molecule khov kho raug cuam tshuam, ua rau muaj kev tiv thaiv cua sov zoo heev thiab kev ua haujlwm rwb thaiv tsev.
Tsab xov xwm tom ntej no peb yuav txuas ntxiv qhia txog cov yam ntxwv ntawm cov khoom siv refractory fiber aluminium silicate. Thov tos ntsoov!
