Cov neeg siv khoom hauv tebchaws Poland tau xaj 195 tons silica cib thiab 80 tons refractory castable
Lub Kaum Ob Hlis. 195 tons silicon cib tau ntim rau kev xa mus rau cov neeg siv khoom hauv tebchaws Poland. Siab zoo silicon bricks thiab refractory castable nyob rau hauv Topower Refractory.
Silica Brick yog cov khoom siv acidic refractory, uas muaj peev xwm ua kom muaj zog hauv cov kua qaub. Lub softening kub ntawm lotus yog siab li 1640 mus rau 1670 degree C. Nws tau ruaj khov rau lub sij hawm ntev ntawm qhov kub thiab txias.
Feem ntau yog siv rau chav carbonization thiab chav kub kub ntawm coke rauv, chav tsev kub cia ntawm steelmaking ca rauv thiab chav tsev sediment, cov khoom siv refractory ntawm nruab nrab cua sov rauv, lub khob fusion kiln, thiab lub cub tawg ntawm lub kiln thiab Lwm cov kiln ntawm ceramics Lorage qhov chaw. Nws kuj yog siv rau qhov kub thiab txias load-bearing qhov chaw thiab acid ca rauv saum lub qhov cub cua kub.
Cov kua qaub refractory cov ntaub ntawv muaj xws li Setrics, Fang quartz, thiab ib tug me me ntawm residual quartz thiab iav. Silicon dioxide cov ntsiab lus yog ntau dua 94 feem pua. Qhov ceev tiag tiag 2.35g / cm3. Nws muaj anti-acid slag yaig kev ua haujlwm. Siab kub siv. Lub softening kub pib kub ntawm 1620 ~ 1670 degree C. Siv nyob rau hauv high kub rau ib ntev lub sij hawm tsis deformation. Tsawg thermal poob siab stability (dej tshav kub yog pauv rau 1 mus rau 4 zaug) nrog ntuj silica raws li raw cov ntaub ntawv, ntxiv rau ib tug tsim nyog tus nqi ntawm mineralizer los txhawb lub transformation ntawm quartz nyob rau hauv lub dawb paug lub cev mus rau hauv lub lizard. Nyob rau hauv cov huab cua rov qab, nws tau maj mam hlawv los ntawm 1350 ~ 1430 degree C. Thaum cua sov mus rau 1450 degree C, muaj li ntawm 1.5 ~ 2.2 feem pua ntawm tag nrho cov o tuaj. Qhov seem seem no yuav ua rau lub seam nruj thiab xyuas kom meej tias cov masonry muaj cov roj nruj zoo thiab cov qauv tsim muaj zog. Symbolics, square quartz, thiab residual quartz hloov pauv vim yog siv lead ua hom ntawm qhov kub thiab txias, thiab qhov ntim tau hloov pauv zoo heev, yog li thermal stability ntawm silica cib ntawm qhov kub tsis zoo. Thaum siv, maj mam rhuab thiab txias hauv qab 800 degree C kom tsis txhob tawg. Yog li ntawd, nws tsis pom zoo kom siv lub qhov cub hloov sai dua li 800 degree C.
Qhov xwm thiab txheej txheem ntawm silica cib yog ze ze rau kev hloov pauv ntawm SIO2. Yog li ntawd, qhov kev faib ua feem yog ib qho tseem ceeb zoo qhia ntawm silica cib. Feem ntau, qis dua 2.38, siab zoo silicon cib yuav tsum qis dua 2.35. Qhov tseeb kev faib ua feem me me, xav txog cov loj ntawm squamous quartz thiab square quartz nyob rau hauv lub cib, qhov seem ntawm cov seem ntawm quartz, yog li cov seem seem yog tsawg inflated, thiab qhov kev siv tsawg tsawg thaum siv. Muaj xya crystalline variants thiab amorphous variant ntawm silicon dioxide. Cov variants no tuaj yeem muab faib ua ob pawg: thawj hom kev hloov pauv yog quartz, squamous quartz, thiab square quartz. Lawv cov qauv siv lead ua yog qhov sib txawv heev, thiab kev sib hloov ntawm ib leeg qeeb heev. ─ thiab hom, lawv cov qauv zoo sib xws, thiab lawv hloov sai dua.
Cov khoom siv raw rau ua silica cib yog silica. Qhov siab dua SIO2 cov ntsiab lus ntawm silicon raw cov ntaub ntawv, qhov siab dua qhov hluav taws kub. Qhov teeb meem impurities feem ntau yog Al2O3, K2O, NA2O, thiab lwm yam, uas txo cov refractory tsis kam ntawm cov khoom refractory.
