Nyob rau lub yim hli ntuj 12tons rwb thaiv tsev refractory hluav tawscorundum mullite cibthiab ceramic fiber pam yog ntim rau xa mus rau cov neeg siv khoom hauv UAE. Zoo siab thiab zoo tshaj tus nqi refractory hluav taws cib hauv Topower Refractory.
High-purity corundum mullite cib hais txog qhov kub-kub refractory cib nrog cov ntsiab lus alumina ntau dua 90 feem pua, feem ntau yog tsim los ntawm corundum thiab ib qho me me ntawm lwm cov khoom ntxiv. Lub ntsiab tivthaiv ntawm corundum cib yog alumina (Al2O3), uas yog ib yam khoom uas muaj hardness siab, siab melting point thiab kub kuj. Nws muaj tshuaj lom neeg ruaj khov thiab muaj zog tiv taus acidic lossis alkaline slag, hlau thiab iav kua.
Ntawm cov tshuaj lom neeg ntawm corundum cib, alumina yog qhov tseem ceeb tshaj plaws, suav nrog feem ntau ntawm tag nrho cov khoom ntawm corundum refractory cib. Corundum yog ib qho ore muaj li ntawm alumina muaju, uas tuaj yeem tsim cov qauv siv lead ua zoo heev ntawm qhov kub thiab txias. Corundum muaj hardness heev, thib ob tsuas yog pob zeb diamond, uas ua rau corundum cib muaj qhov hnav tsis kam thiab Refractory zog. Ntxiv rau alumina, cov khoom siv rwb thaiv tsev corundum hluav taws cib kuj tseem muaj me me ntawm lwm cov khoom ntxiv, xws li silicate, aluminium silicate thiab magnesium aluminate. Lub xub ntiag ntawm cov additives no tuaj yeem txhim kho kev ua haujlwm ntawm corundum cib, xws li nce nws cov hluav taws kub, kev poob siab thiab hnav tsis kam, thiab lwm yam.
Cov txheej txheem kev npaj ntawm corundum mullite cib feem ntau suav nrog cov kauj ruam ntawm cov khoom siv raw xaiv, sib tsoo, molding, sintering thiab kho qhov chaw. Nyob rau hauv cov nqe lus ntawm kev xaiv raw khoom, zoo corundum ore yog lub hauv paus rau kev npaj zoo corundum refractory cib. Cov txheej txheem sib tsoo tuaj yeem ua rau qhov loj ntawm cov khoom siv raw khoom sib xws, uas yog qhov zoo rau cov molding tom ntej thiab sintering. Cov txheej txheem tsim tuaj yeem tsim corundum mullitebricks ntawm cov duab sib txawv thiab ntau thiab tsawg raws li kev xav tau. Sintering yog ib kauj ruam tseem ceeb hauv kev npaj ntawm corundum hluav taws cib. Los ntawm cov txheej txheem sintering ntawm qhov kub thiab txias, cov corundum hais tau ua ke los tsim cov khoom cib lub cev. Thaum kawg, qhov chaw tiav thiab kev zoo nkauj ntawm corundum bricks tuaj yeem txhim kho los ntawm kev kho deg.
Ceramic fiber ntau daim pam, tseem hu ua aluminium silicate fiber pam, yog ib yam tshiab ntawm cov hluav taws kub-resistant thiab kub-insulating khoom. Cov khoom yog xim dawb thiab tsis tu ncua ntawm qhov loj me. Tom qab ob-sided rab koob punching txheej txheem, interweaving degree, anti-delamination kev ua tau zoo, tensile zog thiab nto smoothness ntawm fibers yog zoo heev.
Daim pam fiber ntau tsis muaj cov organic binder los xyuas kom meej tias daim pam ceramic fiber ntau muaj kev tsim tau zoo thiab ruaj khov nyob rau hauv qhov kub thiab txias. Aluminium silicate fiber ntau daim pam colourClean dawb, huv si thiab huv si, nws integrates hluav taws kub tsis kam, rwb thaiv tsev kub thiab kub preservation. Tsis muaj cov binders. existIt tseem tuaj yeem tuav lub zog tensile zoo, toughness thiab fiber ntau nyob rau hauv lub sij hawm ntev siv nyob rau hauv nruab nrab thiab oxidizing atmospheres qauv. Qhov kub tsis kam yog 950-1400 degree . Nws dominates kev siv niaj hnub high-temperature pipelines.
Ceramic fiber ntau daim pam muaj peev xwm tiv thaiv tshav kub, yog li nws tuaj yeem txuag hluav taws xob ntau dua, uas yog tib hom rwb thaiv tsev.
Thermal rwb thaiv tsev cov ntaub ntawv xws li thermal rwb thaiv tsev cib muaj 1.2 npaug ntawm lub zog txuag lub peev xwm, thiab maj mam hloov cov khoom asbestos. Nws qhov zoo dua yog tias nws tsis muaj cov khoom xyaw ua rau tib neeg lub cev.
