Cov ntaub ntawv refractory tseem ceeb heev hauv kev tsim kho niaj hnub thiab kev tsim khoom lag luam. Cov ntaub ntawv refractory xa mus rau cov ntaub ntawv uas muaj cov khoom tshwj xeeb xws li kub tsis kam, hnav tsis kam, tiv thaiv hluav taws, rwb thaiv tsev, thiab lwm yam. Lawv tau dav siv nyob rau hauv high-temperature furnaces, kev tsim kho, aerospace thiab lwm yam kev lag luam, thiab tau dhau los ua ib feem tseem ceeb ntawm cov khoom siv niaj hnub no. .
Cov ntaub ntawv refractory yog dav siv rau lawv cov hluav taws kub zoo, txawm nyob rau hauv cov roj av, tshuaj lom neeg kev lag luam, casting, metallurgy, kev tsim kho, lub zog thiab lwm yam lag luam, los yog nyob rau hauv kev lag luam kev lag luam ntawm lub teb chaws, cov chaw siv hluav taws xob loj, cov tsev loj hauv nroog, tsheb khiav. cov hlab ntsha, thiab lwm yam. ua lub luag haujlwm uas tsis tuaj yeem tsis quav ntsej.
Kev lag luam cov ntaub ntawv refractory tab tom ntsib lub sijhawm ntawm kev loj hlob sai. Ntawm qhov tod tes, nrog kev txhim kho ntawm tib neeg txoj kev ua neej nyob, tib neeg muaj kev xav tau ntau dua thiab siab dua rau kev nyab xeeb, kev tiv thaiv ib puag ncig, kav ntev thiab lwm yam. Ntawm qhov tod tes, nrog kev nce qib txuas ntxiv ntawm cov khoom siv refractory kev lag luam, cov hom thiab cov khoom zoo kuj tseem txhim kho tas li. Cov no tau coj kev lag luam dav dav rau kev thov cov khoom siv refractory.
Cov ntaub ntawv refractory feem ntau yog siv rau hauv kev tsim kho thiab feem ntau yog siv nyob rau hauv ntau qhov chaw xws li kub, noo noo, corrosion, vibration, thiab lwm yam xws li rauv, furnace stacks, kilns, metallurgical khoom, chemical khoom, pob zeb, thiab lwm yam. . Ntxiv rau kev ua kom muaj kev ruaj ntseg ntau lawm, nws kuj tseem txhim kho kev tsim khoom thiab txo kev siv hluav taws xob kom zoo.
Muaj ntau hom khoom siv refractory, feem ntau yog cov khoom siv ceramics, cov ntaub ntawv sib xyaw, cov ntaub ntawv hlau thiab polymer. Ceramic yog cov khoom siv tsis yog xim hlau uas tau txais los ntawm kev tua hluav taws kub. Nws muaj qhov zoo ntawm qhov kub thiab txias, tiv thaiv corrosion thiab rwb thaiv tsev. Cov ntaub ntawv sib xyaw yog tsim los ntawm ntau hom fibers thiab matrix cov ntaub ntawv, uas tuaj yeem ua ke raws li qhov xav tau sib txawv. Lawv muaj cov yam ntxwv ntawm kub tsis kam, hnav tsis kam, oxidation tsis kam thiab poob siab tsis kam. Hlau kuj tseem siv dav hauv cov ntaub ntawv refractory, feem ntau los ntawm nws lub zog siab thiab corrosion tsis kam los xyuas kom ruaj khov thiab kev nyab xeeb ntawm cov khoom siv. Cov khoom siv polymer yog cov khoom siv nrog siab o-phenyl cov ntsiab lus, qhov hnyav molecular, siab saw ntev, tsis tshua muaj qhov hnyav molecular hloov, thiab lwm yam, thiab tuaj yeem tswj tau qhov kev ruaj ntseg hauv qhov kub thiab txias.
Kev siv cov ntaub ntawv refractory yuav tsum tau xaiv cov ntaub ntawv raug thiab tsim kom raug. Yog tias koj xaiv qhov tsis ncaj ncees lawm, nws yuav ua rau hnav, corrosion, to thiab lwm yam teeb meem ntawm cov ntaub ntawv hauv kev siv tiag tiag, cuam tshuam rau kev tsim khoom thiab khoom siv lub neej. Yog li ntawd, thaum siv, koj yuav tsum xyuam xim rau xaiv cov ntaub ntawv uas tsim nyog refractory, thiab nruj me ntsis siv tus tsim, ntau lawm, thiab installation ntawm refractory ntaub ntawv los xyuas kom meej lub sij hawm ntev thiab ib txwm ua hauj lwm ntawm cov khoom.
