Muaj ntau qhov xwm txheej nyob rau hauv cov kab nrib pleb ntawm silica cib: yog tias nws yog txheej txheej ntawm cov kab nrib pleb lossis kab nrib pleb ntawm lub cib, thawj rauj ntawm lub tshuab siab tsis tas siv thaum tsim lub cib. Yog hais tias nws yog kab rov tav los yog mesh-zoo li cov kab nrib pleb, qhov kub nce ceev heev thaum lub sij hawm ziab. Hauv lwm qhov xwm txheej, kev tswj qhov kub tsis raug cai kuj tseem yuav tsim cov kab nrib pleb rau ntawm qhov chaw ntawm silica cib.
Kev tawg yuav tsum tau hais tias yog ib feem tseem ceeb ntawm kev tawm los ntawm silica cib. Yog tias kev tswj tsis raug, tus nqi yuav nce ntxiv.
Silica cib yog cov khoom siv acidic. Piv nrog rau lub siab aluminium bricks ntawm cov khoom nruab nrab, cov khoom tiav cov nqi yog tsawg. Lwm qhov laj thawj tseem ceeb yog qhov nthuav dav coefficient ntawm silica cib siab. Mob hnyav tshaj tus qauv.
Thaum lub sij hawm hlawv ntawm silica cib, cov siv lead ua hloov thiab lub ntim expansion coefficient yog loj, uas yog heev yooj yim mus cracking. Txawm li cas los xij, yog tias nws yog micro-crack, nws tuaj yeem txhim kho cov qauv elasticity.
Cov kab nrib pleb ntawm silica cib muab faib ua cov kab nrib pleb thiab sab hauv. Ntawm lawv, cov kab nrib pleb ntawm lub tshuab siab thiab qhov kub thiab txias raug rho tawm haujlwm. Nws yog qhuav thiab tsis huv, thiab cov khoom ntawm cov dej noo tsis zoo li qub, thiab nws pib tsim los ntawm kub sintering. Yam tsawg kawg 150 meters ntawm qhov cub hlawv rau hauv silica cib, txwv tsis pub, qhov kub thiab txias rwb thaiv tsev ua haujlwm tsis zoo, thiab qhov sib txawv ntawm cov silica cib raug rho tawm haujlwm yog hlawv. Nws yuav siab heev.
Txheej txheej txheej tshwm sim nyob rau hauv cov txheej txheem ntawm cov khoom molding. Cov pwm yog aging los yog lub cib tsis tas, thiab cov khaubncaws sab nraud povtseg yuav tshwm sim. Cov silica cib ntawm txheej txheej tsis tuaj yeem siv. Sab hauv zoo tsis zoo, thiab nws tsis tuaj yeem siv rau qhov kub thiab txias. Qhov no tawg yog tawg.
Yog tias nws yog ib qho mesh tawg, qhov kub thiab txias hloov pauv loj, thiab cov khoom sab hauv tsis sib xws. Lwm qhov yuav yog qhov sib xyaw thiab cov hmoov sib xyaw tsis sib xws thaum lub sijhawm sib xyaw, thiab cov kab nrib pleb yuav tshwm sim.
Silica cib nrog kab rov tav kab nrib pleb tshwm nyob rau sab nraud ntawm lub kiln cib pawg hauv cov txheej txheem ntawm kev hlawv, tshwj xeeb tshaj yog cov khoom lag luam saum toj kawg nkaus. Qhov kub thiab txias yog tsim, thiab txoj kev tua hluav taws ntawm lub tsheb kiln tsis tau tshwj tseg, thiab cov nplaim hluav taws ncaj qha rau ntawm lub cib.
Kev tawg ntawm silica cib kuj muaj feem xyuam rau cov txheej txheem. Yog hais tias muaj ntau yam zoo, cov kab nrib pleb kuj yuav tshwm sim. Qhov zoo ntawm tus neeg sawv cev khi ntxiv thaum lub sij hawm sib piv kuj yuav tawg. Kev ziab tsis tso dej los yog tsis yog kev tshawb fawb hauv kev thauj cov tsheb kiln. Ceev, nws yog qhov teeb meem tsis zoo ntawm kev tawg.
Yog tias koj xav tswj cov kab nrib pleb ntawm silica cib, koj yuav tsum los ntawm cov khoom siv raw khoom mus rau qhov tsim ntawm molding thiab firing. Cov txheej txheem ntawm kev tsim cov txheej txheem yog tswj xyuas tiag tiag. Txhua qhov txuas yuav tsum tau them sai sai rau. Yog tias lub sijhawm los tswj cov cib hlawv, nws yuav daws tau qhov tshwm sim ntawm cov kab nrib pleb.
