Silica Cib

Silica cib yog cov khoom siv refractory nrog silicon oxide (Sio2) raws li lub ntsiab tivthaiv. Silica cib rau qhib rauv thiab silica cib rau cke cub.

Performance Silica cib muaj lub siab refdacting zoo nyob rau hauv thauj, uas tsuas yog 30 ~ 50 degree txawv ntawm kev ua haujlwm tsis muaj hluav taws xob tsis muaj. Lub ntim nthuav los ntawm kev hloov pauv lead ua ntej thaum cua sov ua ntej 600 degree, yog li cov neeg tsis zoo nyob rau theem kub, tab sis zoo heev rau theem kub kub. Qhov qis qis ntawm cov khoom tuaj yeem txo tau lub zog ntawm lub cub tawg. Silica Cib Raw Khoom siv dav faib thiab yooj yim rau kuv. Cib tuaj yeem ua tau yam tsis muaj ore hnav ris tsho, yog li tus nqi yog tsawg.

 

Silica Cib Cov Txheej Txheem Silica: sillica lossis quartzite yog crushed rau tsawg dua 3mm, thiab tom qab ntawd av rau hauv cov hmoov nplej zoo dua li {1}}. 088mm los ntawm pob zeb zoo sib tsoo. Cov khoom siv raw ntawm ntau qhov ntau thiab tsawg yog qhov tsim nyog tau raws li cov khoom lag luam thiab cov ua tau zoo. Txhawm rau kom txo cov khoom loj thaum tua hluav taws, pov tseg silica Cib Bricks account rau 5% rau 20% ntawm tag nrho cov nyiaj tuaj yeem ntxiv.

Txiv qaub (feem ntau ntxiv rau hauv daim ntawv ntawm txiv qaub mis), hlau oxide thiab lwm cov laberalizers uas muaj peev xwm cuam tshuam nrog qhov kub thiab txias tsis cuam tshuam nrog cov khoom xyaw. Cov theem ua kua tuaj yeem txhawb kev hloov pauv ntawm Quartz los tridymite thiab tuaj yeem txo cov kev ntxhov siab los ntawm kev nthuav dav thaum lub sijhawm tua hluav taws, yog li txo cov kab nrib pleb hauv cov khoom. Cov ntaub ntawv raw ua saum toj no thiab cov ntxhia tau sib xyaw ua ke hauv lub zeb ntub thiab ib phau ntawv Sulfite pulp pov tseg tau ntxiv. Cov av nkos tau muab tso rau hauv lub cib pwm thiab ua rau hauv lub pob zeb dawb paug los ntawm lub tshuab lossis tes. Lub cib dawb yog qhuav hauv lub tshuab ziab khaub ncaws qhov chaw lossis lub tshuab ziab khaub ncaws, thiab qhov pib kub tsis ntau tshaj 7 {5}} degree. Cov kab mob siab loj dua 40kg yuav tsum tau qhuav hauv huab cua rau ntau tshaj 48 teev. Cov dej noo noo ntawm cov cib qhuav tsis ntau tshaj li 1%, thiab cov ntsiab lus noo ntawm cov cib loj tsis ntau tshaj 0.5%. Tom qab cov tsos thiab hla-ntu tshuaj xyuas, lawv raug rho tawm haujlwm hauv qhov cub, xwj xilns. Qhov siab tshaj plaws hluav taws kub yog 1380 ~ 1450 degree, uas txawv raws nyob ntawm tus Quartz hloov dua siab tshiab nyob rau hauv cov ntaub ntawv raw thiab cov khoom zoo tshaj plaws ntawm cov khoom. Kev tua hluav taws yog qhov txheej txheem tseem ceeb thiab kev nkhaus cua sov yuav tsum ua nruj ua ntej. Cov khoom txias yuav tsum tau kuaj xyuas ib daim. Cov tsos yuav tsum tsis tu ncua, thiab qhov sib txawv ntawm sab thiab nplaim degraus xws li melting qhov thiab cov kab nrib pleb yuav tsum tsis txhob tshaj cov cai.

Cov txheej txheem tsim tau kev txiav txim siab cov ntxhia ntawm Silica Cib. Nyob rau hauv tib lub cev tua hluav taws, cov khoom lag luam nrog cov ntsiab lus me me thiab cov ntsiab lus zoo rau Cokee rau Coke Ovens thiab Silica Cib rau kub ntshiab tshuab. Silica bricks rau iav kilns yuav tsum tau sio2 cov ntsiab lus thiab tsawg dua cov ntxhia pob zeb ntxiv, yog li cov thwv cib muaj ntau quartz.

Lub ntsiab tseem ceeb cov ntxhib muaj pes tsawg ntawm silica cib ntawm chav sov yog kev sib xyaw ntawm -tridymite, -crristobalite, -cristobalite thiab -Quarz. Cov kev sib tw sib txawv sib txawv raws li cov txheej txheem sib txawv, xws li ntawm -cristobalite 15% ~ 6}}% -Qhia}% -quartz 0% ~ 10%

Silicon Cib feem ntau yog siv nyob rau hauv Coke ncu, moj tej tawg sov ua kom sov, thiab qee lub teb chaws tseem siv cov pob zeb Silica ntau ntxiv rau cov tshuab hluav taws xob.

Silicon Cib yuav tsum muab cia rau hauv cov chaw tsim khoom uas tsis muaj dej hauv dej thiab tseem tuaj yeem siv tom qab tau maj mam qhuav hauv qab 100 degree tom qab tau tasmp. Lub zog ntawm cov dej-muaj silica cib cuam tshuam los ntawm khov thiab yuav tsum tau rov kuaj dua. Thaum tsim kom muaj cua sov, nthuav tawm pob qij txha yuav tsum tau tawm mus raws li cov qauv nthuav tawm muab los ntawm cov chaw tsim khoom. Lub sij hawm kub-sij hawm nkhaus thiab muaj sij hawm siv yuav tsum tau tsim kom muaj kev tsim nyog, tshwj xeeb tshaj yog nyob rau hauv theem ntawm ntau qhov nthuav dav ua ntej 600 degree, uas yuav tsum nruj me ntsis tswj.

Microstructure ntawm Silicous Refractory Cov Ntaub Ntawv

Silica bricks yog tsim los ntawm ntau theem heterogeneous qauv ntawm tridymeneous qauv, silicate quarmalz, silicate, silicate thiab iav theem thiab iav ua si. Orthotorhombic tsawg -Tus-kub -tridymite feem ntau muaj nyob rau hauv daim ntawv ntawm ib tug kev hloov pauv ntawm hexagonal high-sedformymite, lossis tsim ib qho "ntxaib Crystal nrog A (10T6) ntxaib sib luag. Qhov ntim feem thiab tus nqi sib txuas lus ncaj qha ntawm -tridymite yog quantitaters tsis tau soj ntsuam cov degree thiab txuas ntxiv ntawm tus qauv network.

Piv txwv, calcium hlau pybes, calcium hlau Olivine thiab dicalcium Silicate thiab dicalcium Silicate, uas yog dispersed nyob rau hauv voids ntawm tridymite network. Tsis xwm yeem cov hlau oxides kuj tseem tuaj yeem tshwm sim hauv matrix hauv daim ntawv ntawm -fe2O3 theem. Metastable los yog ruaj khov Cristobalite, Residual Quartz, thiab lwm yam. Txheeb xyuas cov qauv txheej txheem particle. Metastable Cristobalite yog qhov ntsuas me me ntawm -cristobalite ntawm 870 thiab 1470 degree. Nws qhia cov homogeneous nyob rau hauv ib lub cev polarization thiab yog qhov nyuaj kom paub qhov txawv ntawm cov duab hluav taws xob nyob rau hauv lub x-ray diffraction spectrum. Nyob rau hauv thaum ntxov theem ntawm kev hloov ntawm -Quotz los ntsuas Cristobalite, Metastable Cristobalite cov ntaub ntawv txuas ntxiv mus rau hauv cov quartz mus rau hauv Islands tuaj. Raws li cov txheej txheem thermal txuas ntxiv mus, cov ntim ntim ntawm cov chaw seem quartz txo lossis ploj los ntawm cov qauv txheej txheem particle. Cov tshuaj ntsuab xim av txheej ntawm ntug ntawm cov particle yog tsim ntawm iav theem, thiab yog hom kev sib cuam tshuam ntawm cov mineralization hauv matrix thiab cov lus.
