khib nyiab
Pov tseg cov raj xaim, cov xov hlau, cov txiv ntoo thiab lwm cov khib nyiab, qhib cov xov hlau, cov hlau ntes.
Khawb
Nyob rau ntawm qhov nkag ntawm lub crusher, ib khub ntawm rollers yuav tsum tau ntsia los tswj tus nqi ntawm cov khoom noj.Cov khoom yog 5 hli luv fiber ntau thiab hmoov nrog finer particle loj: thib ob crushing tom qab ziab, ntxiv rau huab cua xaiv ntaus ntawv.
Kev tu cov khib nyiab
Tom qab yaug nrog dej, tus neeg saib xyuas qhov loj me uas txuas nrog cov fiber ntau yuav raug ntxuav, thiab cov dej khib nyiab yuav raug ntxuav, thiab cov dej kho los ntawm cov chaw kho dej phwj tuaj yeem siv tau, yuav luag tsis muaj dej kais dej.Cov dej ntxuav tau rov qab mus rau qhov chaw kho dej phwj tuaj kho.Cov rinsed fibers yog thawj zaug sib cais los ntawm cov dej los ntawm ib tug xuab zeb dej separator.
khib nyiab kom qhuav
Nws raug xa mus rau lub tshuab ziab khaub ncaws los ntawm winch kom qhuav tas li.Lub elevator muaj kev ua haujlwm ntawm kev hloov pauv ceev ceev, thiab kev pub noj ceev yuav cuam tshuam rau cov ntsiab lus noo ntawm cov khoom qhuav.Lub zog qhov chaw ntawm lub tshuab ziab khaub ncaws yog cov nkev ntuj, uas yog chav qhuav thiab ces qhuav los ntawm ib lub kiln.Cov ntsiab lus fiber ntau tom qab ziab yog tsawg dua 1%.Raws li kev xav tau ntau lawm, nws tuaj yeem muab tso rau hauv lub tso tsheb hlau luam lossis lub hnab loj rau kev muag khoom, lossis nws tuaj yeem raug xa mus rau pneumatically thauj mus rau lub thawv siv.
Kev siv cov khoom siv khib nyiab
1. Daim ntawv thov nyob rau hauv tas li fiber ntau lawm
Thov nco ntsoov cov ntsiab lus hauv qab no:
1 Lub taub hau kiln tau nruab nrog kev pub mis ob sab, thiab cov nyiaj pub rau ob sab yog sib npaug li qhov ua tau.
2. Nws yuav tsum tau qhuav li sai tau, thiab qhov zoo tshaj noo noo cov ntsiab lus yuav tsum tsis txhob ntau tshaj 1%, uas kuj yog cov ntaub ntawv rau alkali-dawb kilns.
3 Qhov loj ntawm cov ntaub lo lo ntxhuav uas tsis yog-alkali tuaj yeem ua nyias, thaum lub nruab nrab alkali txhob lo lo ntxhuav yog qhov sib txawv, nws yuav tsum tuab li ntau tau.
4 Ntxiv volatile Cheebtsam B thiab F rau cov tshuaj muaj pes tsawg leeg ntawm iav fiber.
2. Daim ntawv thov hauv iav wool ntau lawm
1 Txij li cov khoom ntawm nruab nrab-alkali iav fiber ntau thiab nruab nrab-alkali iav ntaub plaub yog tib yam hauv 5, nruab nrab-alkali khib nyiab tuaj yeem siv ncaj qha los tsim alkali hlau-alkali iav ntaub plaub.
2 Cov muaj pes tsawg leeg ntawm alkali-dawb iav fiber ntau yog piv nrog cov iav tsis muaj alkali:
kev sib piv
Los ntawm kev sib piv, nws tuaj yeem pom tias tsuas yog qhov sib txawv ntawm CaO thiab MgO, tsuas muaj qhov sib txawv me me ntawm lwm cov khoom xws li Si, Al, B thiab R2O.Hauv kev tsim khoom, cov khoom siv raw nkag mus rau hauv cov qauv qub ntawm CaO thiab MgO feem ntau yog ntxiv, thiab cov khoom xyaw ntxiv tuaj yeem hloov kho me ntsis kom tau raws li qhov xav tau ntau lawm.
3. Daim ntawv thov hauv cov qauv iav ntau lawm
Kev tsim cov qauv iav siv cov khoom siv khib nyiab tau piav qhia.Cov txheej txheem tseem ceeb yog npaj cov muaj pes tsawg leeg zoo ib yam li cov qauv iav raws li cov yam ntxwv ntawm cov khoom nruab nrab thiab tsis-alkali khib nyiab raws li 2: 1 piv ntawm nruab nrab thiab tsis-alkali khib nyiab.Cov lus hauv qab no:
Los ntawm kev siv quartz xuab zeb thiab dej qab zib tshauv, cov khoom siv xws li qis SiO2, R2O thiab siab CaO, MgO, Al2O3 raug kho kom tsim tau cov qauv muaj pes tsawg leeg uas ua tau raws li cov kev xav tau ntau lawm.Lub approximate formula yog raws li nram no:
Thaum lub sij hawm tsim khoom, yuav tsum tau saib xyuas kom zoo tswj qhov kub thiab txias (txog 570 ° C) thiab molding kub.
4. Daim ntawv thov hauv iav mosaic ntau lawm
Kev tsim cov iav mosaics siv qhov nruab nrab thiab tsis-alkaline khib nyiab lo lo ntxhuav tau siv ntau xyoo.Vim yog cov xim sib txawv ntawm iav mosaics, kuj tseem muaj qee qhov sib txawv ntawm cov khoom sib xyaw.Raws li kev sib xyaw ua ke ntawm cov xim sib txawv, xaiv siv cov khoom siv nruab nrab lossis tsis-alkaline khib nyiab.Txawm li cas los xij, txhawm rau ua kom tau raws li qhov yuav tsum tau ua ntawm cov khoom xim thiab thermal stability, tshuaj stability, mechanical zog, thiab lwm yam, nws yog ib qho tsim nyog yuav tsum tau hloov kho cov muaj pes tsawg leeg, thiab ntxiv cov zaub mov xws li silica xuab zeb, limestone, feldspar potassium, albite, thiab lwm yam. nahcolite.Tshauv, fluorite, thiab lwm yam. Cov khoom siv raw thiab cov xim sib txawv.
5. Siv ceramic fiber pov tseg txhob lo lo ntxhuav los tsim ceramic glaze
Cov khoom tseem ceeb ntawm iav fiber ntau yog tag nrho cov khoom tsim nyog rau ceramic glaze, tshwj xeeb tshaj yog 7% B2O3 hauv alkali-dawb fiber ntau.Nws yog ib qho khoom muaj nyob rau hauv glazes, uas tuaj yeem txo qhov kub ntawm glazes, tiv thaiv glazes los ntawm cracking thiab txhim kho glazes.Deg hardness, gloss thiab tshuaj tsis kam.Vim yog tus nqi siab ntawm boron raw cov ntaub ntawv, qhov feem ntawm glaze nqi yog siab heev.Kev siv tag nrho ntawm cov khoom siv tseem ceeb ntawm cov khoom siv khib nyiab tuaj yeem txo cov nqi tsim khoom ntawm glazes.
