Muaj ntau ntau yam ntaub ntawv, yuav ua li cas refractory cov ntaub ntawv cais raws li cov ntaub ntawv rwb thaiv tsev kub?Feem ntau, nws tuaj yeem raug cais raws li cov khoom siv, qhov kub thiab txias, cov duab thiab cov qauv.Raws li cov khoom siv, nws tuaj yeem muab faib ua peb hom: muaj cov ntaub ntawv, cov ntaub ntawv tsis-polar rwb thaiv tsev thiab cov ntaub ntawv hlau.
Cov ntaub ntawv rwb thaiv tsev rau cov khoom siv thermal thiab cov kav dej: Cov khoom siv no muaj cov yam ntxwv ntawm kev lwj, tsis muaj hluav taws xob, thiab kub tsis kam.Piv txwv li: asbestos, diatomaceous ntiaj teb, perlite, iav fiber, ua npuas ncauj iav, calcium silicate board, thiab lwm yam.
Hauv cov khoom siv rwb thaiv tsev txias, cov khoom siv hluav taws xob hluav taws xob feem ntau yog siv.Cov khoom siv no muaj cov yam ntxwv ntawm cov thermal conductivity me me, tsis kub tsis kam, thiab nplaim taws.Piv txwv li: polyurethane, seev cev vinyl ua npuas ncauj, urethane ua npuas ncauj, cork, thiab lwm yam.
Raws li daim ntawv, nws tuaj yeem muab faib ua cov ntaub ntawv thermal rwb thaiv tsev, fiber ntau thermal rwb thaiv tsev cov ntaub ntawv, hmoov thermal rwb thaiv tsev thiab txheej txheej thermal rwb thaiv tsev cov ntaub ntawv, uas yog lub teeb, zoo thermal rwb thaiv tsev kev ua tau zoo, zoo elasticity, ua npuas ncauj yas, ua npuas ncauj iav, ua npuas ncauj roj hmab, calcium silicate, Lightweight refractory khoom, thiab lwm yam. Fibrous thermal rwb thaiv tsev ntaub ntawv yuav muab faib ua organic fibers, inorganic fibers, hlau fibers thiab puas fibers raws li lawv cov ntaub ntawv.Hauv kev lag luam, inorganic fibers feem ntau yog siv los ua cov khoom siv thermal rwb thaiv tsev.Tam sim no, cov fiber ntau siv ntau tshaj plaws yog asbestos, pob zeb wool, iav ntaub plaub, aluminium silicate ceramic fibers, thiab crystalline oxidized thermal cov ntaub ntawv feem ntau suav nrog lub ntiaj teb diatomaceous thiab nthuav pearls.Pob zeb thiab nws cov khoom.Cov ntaub ntawv no muaj cov khoom lag luam nplua nuj thiab cov nqi qis.Lawv yog cov khoom siv thermal rwb thaiv tsev zoo heev siv dav hauv kev tsim kho thiab cov khoom siv thermal.paub meej raws li hauv qab no.
Foam-hom rwb thaiv tsev khoom.Ua npuas ncauj rwb thaiv tsev cov ntaub ntawv feem ntau muaj xws li ob pawg: polymer foam insulation cov ntaub ntawv thiab ua npuas ncauj asbestos rwb thaiv tsev cov ntaub ntawv.Polymer foam rwb thaiv tsev cov ntaub ntawv muaj qhov zoo ntawm qhov nqus dej tsawg, cov nyhuv rwb thaiv tsev ruaj khov, tsis tshua muaj thermal conductivity, tsis muaj plua plav ya thaum siv, thiab kev tsim kho yooj yim.Lawv yog nyob rau hauv lub sij hawm ntawm popularization thiab daim ntawv thov.Foamed asbestos thermal rwb thaiv tsev cov ntaub ntawv kuj muaj cov yam ntxwv ntawm tsawg ntom, zoo thermal rwb thaiv tsev kev ua tau zoo thiab yooj yim siv.Qhov nrov ntawm sodium yog qhov ruaj khov, thiab daim ntawv thov cov nyhuv kuj zoo.Tab sis tib lub sijhawm, cov thom khwm yooj yim kom ntub dej, yooj yim rau yaj hauv dej, muaj qhov me me elastic rov qab coefficient, thiab tsis tuaj yeem siv rau hauv ib feem ntawm cov yeeb nkab phab ntsa thiab nplaim taws.
Composite silicate rwb thaiv tsev khoom.Composite silicate rwb thaiv tsev cov khoom muaj cov yam ntxwv ntawm cov yas muaj zog, tsis tshua muaj thermal conductivity, kub tsis kam, thiab me me kom qhuav shrinkage ntawm slurry.Cov hom tseem ceeb yog magnesium silicate, silicon-magnesium-aluminium, thiab cov khoom siv hluav taws xob tsawg hauv ntiaj teb.Nyob rau hauv xyoo tas los no, cov khoom siv thermal rwb thaiv tsev sepiolite, ua tus thawj coj ntawm cov khoom siv hluav taws xob silicate thermal rwb thaiv tsev, tau ua rau muaj kev sib tw ua lag luam thib ob thiab kev lag luam dav ntawm kev tsim kho kev lag luam vim nws cov thermal rwb thaiv tsev zoo thiab daim ntawv thov.kev lag luam kev cia siab.Cov khoom siv thermal rwb thaiv tsev sepiolite yog tsim los ntawm cov khoom siv tshwj xeeb uas tsis yog xim hlau-sepiolite ua cov khoom siv tseem ceeb, ntxiv los ntawm ntau yam metamorphic ntxhia raw cov ntaub ntawv, ntxiv cov additives, thiab siv cov txheej txheem tshiab los ua npuas dej sib xyaw.Cov khoom siv tsis muaj tshuaj lom thiab tsis qab, thiab yog grey-dawb electrostatic inorganic muab tshuaj txhuam, uas yog grey-dawb kaw network qauv tom qab qhuav thiab tsim.Nws cov yam ntxwv tseem ceeb yog cov thermal conductivity tsawg, qhov kub thiab txias ntau, tiv thaiv kev laus, acid thiab alkali tsis kam, lub teeb yuag, suab rwb thaiv tsev, nplaim taws retardant, kev tsim kho yooj yim, thiab tus nqi qis tag nrho.Feem ntau yog siv rau thermal rwb thaiv tsev ntawm lub ru tsev thiab sab hauv qab nthab ntawm chav tsev kub, nrog rau cov khoom siv thermal ntawm roj av, tshuaj, hluav taws xob, smelting, tsheb thauj mus los, lub teeb kev lag luam thiab lub teb chaws tiv thaiv industries, pipeline thermal rwb thaiv tsev thiab chimney sab hauv phab ntsa, rauv plhaub rwb thaiv tsev. (txias) engineering.Cov ntaub ntawv rwb thaiv tsev sov yuav ua rau muaj qhov xwm txheej tshiab.
Calcium silicate thermal rwb thaiv tsev khoom thermal rwb thaiv tsev khoom.Calcium silicate thermal rwb thaiv tsev cov khoom siv thermal rwb thaiv tsev yog ib zaug lees paub tias yog ib qho zoo dua ntawm cov khoom thaiv thermal rwb thaiv tsev nyob rau xyoo 1980s.Nws yog tus cwj pwm tsis tshua muaj zog, siab kub ua kom tsis kam, qis thermal conductivity, siab tsis kam, thiab shrinkage.me me.Txawm li cas los xij, txij li xyoo 1990, nws qhov kev nce qib thiab kev siv tau pom muaj dej ntws tsawg.Muaj ntau manufacturers siv pulp fiber.Txawm hais tias cov txheej txheem saum toj no daws cov teeb meem tsis muaj asbestos, cov ntaub ntawv fiber ntau tsis tiv taus qhov kub thiab txias, uas cuam tshuam rau qhov kub thiab txias tsis kam ntawm cov khoom siv rwb thaiv tsev thiab ua kom cov bong.Thaum cov khoom siv hluav taws xob qis yog siv rau hauv qhov chaw uas muaj qhov kub thiab txias, qhov ua tau zoo ntawm cov khoom siv hluav taws xob hluav taws xob tsis zoo.
Fiber insulation khoom.Kev sib koom thoob ntiaj teb ntawm cov ntaub ntawv fiber ntau thermal rwb thaiv tsev yog vim nws muaj peev xwm zoo sib haum xeeb, thiab feem ntau yog siv rau thermal rwb thaiv tsev rau lub cev lub tsev.Txawm li cas los xij, vim muaj kev nqis peev loj, tsis muaj ntau lub tuam txhab, uas txwv tsis pub nws nce qib thiab siv, yog li kev lag luam sib faib ntawm theem no kuj tsawg.
Cov ntaub ntawv saum toj no muaj feem xyuam nrog kev faib tawm ntawm cov khoom siv hluav taws xob rwb thaiv tsev thiab cov ntaub ntawv refractory qhia los ntawm cov tuam txhab kev tiv thaiv hluav taws xob.Tsab ntawv los ntawm goldenpower Group http://www.goldenpowerjc.com/.Thov qhia lub hauv paus rau kev luam tawm dua.
