Cov yam ntxwv ntawm Ceramic Fiber ntau yog dab tsi?

Tso Sijhawm: 2025-07-30

Kev faib:

Nyob rau hauv high-kub-kub kev lag luam xws li metallurgy, thiab kilrochemicals, thiab kub tsis tshua muaj kev txwv thiab cov khoom siv rwb raws li muaj kev nyab xeeb rau kev nyab xeeb. Rosewool cov pam vov vov vov, nrog nws cov kev tiv thaiv kub zoo heev, tau dhau los ua cov kev daws teeb meem rwb thaiv tsev rau cov kev mob siab.

Cov pam vov ceramic fiber ntau yog tsim los ntawm high-puric alumina thiab silica raw khoom, uas tau melted, tshuab ua ke rau hauv fibers, thiab tom qab ntawd rab koob-punched ua cov duab. Nws tuaj yeem tiv thaiv kom ntau kub ntawm 1260 ℃ rau ib lub sijhawm ntev thiab ib qho kub ntawm 1400 ℃, deb dhau ntawm cov ntaub ntawv rwb thaiv tsev. Nrog lub cheeb tsam fiber ntau ntawm tsuas yog 3-5μm, cov qauv sib txuas ntawm cov qauv sib txuas lus hauv lub thermal conductivity tsawg li 0.03W / (mx k). Hauv kev siv hluav taws xob siab tua cov ntawv thov, nws tuaj yeem txo cov cua sov los ntawm ntau dua 30%.

Muab cov duab nyuaj ntawm cov cuab yeej siv tau, cov khoom yog yoog raws thiab tiv taus nws yuav txiav ncaj qha thiab qhwv ib ncig ntawm cov kav dej tsis sib xws thiab cov cua sov. Nws teeb tsa kev teeb tsa yog 50% siab dua li ntawm kev ua liaj ua teb. Tsis tas li ntawd, nws ua rau pom cov tshuaj ruaj khov zoo, ua kom cov kua qaub zoo nkauj, thiab tswj hwm kev ua tau ruaj khov txawm tias sulphur-muaj flue roj. Nws cov kev pabcuam lub neej yog tshaj 6 xyoo.

Cov yam ntxwv ntawm Ceramic Fiber Pam

Zoo siab siab kub-kub kuj tsis kam: Cov pam vov cov ceramic muaj cov pam sov tuaj yeem tiv taus qhov kub ntev, thiab muaj peev xwm tseem ceeb ntawm cov qauv sib txawv), thiab tuaj yeem tiv taus qhov kub siab dua rau lub sijhawm luv luv. Lawv tsim nyog rau cov pa taws kub xws li cov tshuab hluav taws xob muaj kev muaj zog thiab cov khoom siv kub siab ntawm cov ntaub ntawv rwb thaiv tsev (xws li cov pob zeb tsiaj thiab iav plaub).
Lub teeb yuag thiab kev rwb thaiv tsev zoo heev: Cov khoom muaj qhov ceev qis (feem ntau ntawm 96-128 kg / m³), yog lub teeb nyob rau hauv qhov hnyav, thiab tuaj yeem txo cov thauj khoom ntawm cov khoom siv. Nws cov qauv fibrous xoob xoob xoob xoob xoob thiab muaj qhov ua kom muaj cua sov thiab ua kom muaj kev txuag tshuaj tua hluav taws kub thiab kev siv hluav taws xob.
Zoo tshuaj ruaj khov: Nws muaj lub zog tiv taus rau feem ntau cov acids, alkalis, ntsev ua tau zoo, thiab muaj peev xwm tswj tau ruaj khov rau ib puag ncig corrosive, nrog lub neej kev pabcuam ntev ntev.

Raws li cov kws tshaj lij kev tsim khoom, Rosewool kev vam meej ntawm cov kab ntau lawm thiab tuaj yeem muab cov khoom lag luam ntau yam nrog cov neeg siv khoom sib txawv, nrog rau cov qhua tuaj noj mov kev txhawb nqa. Txhua yam khoom tau dhau SGS ib puag ncig kev sim thiab yog Asbestos thiab hnyav hlau dawb, tsis muaj kev phom sij, ntsuas kev nyab xeeb ntau thiab ua haujlwm.

Xaiv Rosewool Ceramic Ceramic Pam Txiaj Ntsig txhawm rau tsim cov txheej txheem rwb thaiv tsev zoo rau cov khoom kub siab. Tiv tauj peb tam sim no kom tau txais cov tshuaj uas tsim nyog, ua cov chaw muaj kev lag luam siab khiav hluav taws xob ntau-ua tau zoo thiab tso siab.

Dab tsi yog qhov ua tau zoo ntawm nano-rwb thaiv tsev cov laug cam?

Nano rwb thaiv tsev board yog ib qho khoom siv tshiab siv cov hmoov loj hauv cov coefficent coefficient txawm qis dua li ntawd ntawm huab cua. Thaum muaj kub kub, nws cov cua sov rwb thaiv tsev ua tau zoo yog 2-3 zaug zoo dua li cov ntaub ntawv rwb thaiv tsev fiber ntau dua, ua rau kev ua haujlwm kub tshaj tshav ntuj ua haujlwm rau hnub tim.
