Diaomite rwb thaiv tsev cib yog rwb thaiv tsev refractory khoom ua los ntawm diaomite raws li cov khoom siv tseem ceeb. Silica rwb thaiv tsev cib tau nplua kaw pores, zoo heev thermal rwb thaiv tsev ua tau zoo, tshwj xeeb yog tom qab tsis muaj zog, lub zog poob qis. Nws lub cim tshuaj muaj pes tsawg leeg yog Sio :, ua raws los ntawm Al, O :, thiab impurities xws li hlau, potassium, thiab magnesium oxides.
Diaomite rwb thaiv tsev cib cib txheej txheem suav nrog tsib ntu: cov ntaub ntawv raw thiab lawv cov kev ua, moulding thiab tua hluav taws.
Cov ntaub ntawv raw thiab ua cov ntaub ntawv loj raw rau kev tsim cov tshuaj tiv thaiv tsis sib xws ntawm lub ntsej muag sovbs yog diatomite, yoov tshauv, rwb thaiv tsev cib rov qab cov ntaub ntawv. Diaomite muaj ib qho kev muaj zog. Cov khoom ua tiav zoo, qhov zoo dua cov plasticity. Diatomite siv rau lub cib ua yuav tsum tau ua kom tau raws li cov yuav tsum tau ua hauv qab no: Sio2 cov ntsiab lus tseem ceeb tshaj 65%; A10, cov ntsiab lus tsawg dua 18%; FE2O3 cov ntsiab lus tsawg dua 7%; Kev txo qis tsawg dua 14%. Txhawm rau txhim kho cov plasticity ntawm diatomite thiab tshem tawm qee cov ntsev solubite (impurities) los txhim kho nws lub cev siv zog thiab tshuaj, yuav tsum muaj qee lub sijhawm huab cua ua ntej siv. Rau raw khoom ua kev ua tiav, cov qauv sib txawv yog siv raws li qhov ua tau zoo thiab txheej txheem ntawm diaomite. Qee tus yuav tsum tau tsoo kom tsawg dua 1.5 hli, qee tus yuav tsum tau ua rau cov av nkos me me yuav tsum tau muab cov av nkos me me, thiab qee tus yuav tsum muaj dej nrog dej. Cov dej noo cov ntsiab lus ntawm cov yoov tshauv hauv cov nroj tsuag hluav taws xob yuav tsum tsawg dua 26%. Cov dej noo cov ntsiab lus ntawm sawdust yuav tsum tsawg dua 50%, thiab qhov loj me me yuav tsum tsawg dua 1 hli. Khib thiab cov khoom siv ua dua tshiab yuav tsum yog sieved tom qab crushing (pov tseg los ntawm 1.5mm sieve, thiab ntxiv rau cov ntaub ntawv hloov dua tshiab raws li kev faib tawm. Txhawm rau ua cov khoom siv cib muaj cov khoom molding zoo dua qub, qee cov tuam ntxhab ntxiv cov khoom siv thiab cov roj ntsha, sulfite pulp khib nyiab ua kua thiab kib.
Cov khoom xyaw thiab kev sib xyaw ntawm diatomite rwb thaiv tsev cib kom txo tau cov kab nrib pleb thiab pov tseg, ib qho kev ua kom qhuav thiab clinker ntxiv rau cov khoom xyaw; Thaum tsim cov khoom lag luam tsawg, qee qhov ua feem ntawm sawdust kuj ntxiv rau cov khoom xyaw. Qhov kev faib ua feem ntawm ntau yam khoom siv tau txiav txim siab raws li cov khoom lag luam, cov cai kom ua tau zoo, yoog thiab kev phom sij thiab lwm yam kev ua haujlwm. Kev sib xyaw yog nqa tawm hauv ob sab-ncej tov lossis tov khoom. Thaum qhov kub thiab txias, dej kub thiab dej kub yuav tsum tau qhia. Cov av noo cov ntsiab lus ntawm cov av nkos sib txawv raws li cov qauv moulding thiab hom, feem ntau 35% txog 50%.
Cov khoom lag luam
Diaomite rwb thaiv tsev cib molding bricks feem ntau yog tsim los ntawm extrusion molding, tshuab nias Moulding thiab Phau Ntawv Moulding thiab Phau Ntawv Molding.
(1) Extrusion Moulding. Cov av nkos yog pub rau hauv Extruder kom tau cov av nkos extri cov loj, thiab tom qab ntawd txiav rau hauv cov tuab tuab lossis ntev los ntawm lub tshuab txiav.
(2) tshuab nias moulding. Nias rau hauv lub cib xovxwm nrog lub zog nominal ntawm 150 mus rau 300 kn, tab sis thaum lub txheej txheem tawg thiab tawg vim yog elasticmeffect yuav tsum tiv thaiv.
(3) Kev tuav molding. Cov khoom me me, cov duab sib xyaw thiab cov khoom loj yog tsim Manually nrog cov pwm ntoo. Kom qhuav yog nqa tawm hauv kev ua kom sov siab lossis lub tshuab ziab khaub ncaws. Txij li thaum noo noo cov ntsiab lus ntawm cov cib yog qhov siab, qis kub thiab qeeb ziab yuav tsum tau siv kom tsis txhob tawg. Thaum ziab nyob rau hauv lub tshuab ziab khaub ncaws lub tshuab ziab khaub ncaws, lub hauv plab yuav tsum tau tswj hwm ntawm {{1} degree thiab lub qhov hluav taws xob tau nyob ib puag ncig 150 degree; Thiab cov cua ntim tau txaus yuav tsum muab rau. Cov qoob loo uas muaj qab ntawm cov cib tom qab ziab yuav tsum tswj hwm qis dua 3%, thiab cov khoom lag luam loj lossis cov nyom hauv qab no 1%.
Txoj kev "Zoo" yog siv rau KILN thauj khoom, thiab qhov siab stacking tsis pub tshaj 1.5m. Thaum tua hluav taws, nyob rau theem qis (qis dua 20c), lub hom phiaj tseem ceeb yog tshem tawm cov dej lub cev, thiab qhov kub yuav tsum tsis nce nrawm. Thaum lub sijhawm ua haujlwm, kho lub rooj loog, nce lub zog nqus dej hauv lub kiln, thiab yog li ua pa tau ntim. Tom qab 200c, siv lead ua dej thiab cov qauv sib txawv pib pib muab tshem tawm. Cov teeb meem organic xws li sawdust hauv {{4 4} qib degree yuav tsum tswj kom muaj huab cua los pab txhawb tag nrho cov kev sib txuas ntawm cov ocegic teeb meem. Qhov kawg hluav taws kub hluav taws xob kub yuav tswj tau nyob ib puag ncig 900 degree. Qee cov khoom siv rho tawm haujlwm yuav tsum tau ua kom tiav rau hauv cov khoom tiav.
Daim ntawv thov ntawm Diatomite rwb thaiv tsev cib Qhov kub tsis kam ntawm cov khoom tsuas yog li ntawm 1280 degree, yog li siv tau nyob rau hauv cov rwb thaiv tsev txheej qis 900 degree.
Diatomite rwb thaiv tsev cib yog rwb thaiv tsev cov khoom ua los ntawm cov khoom khav theeb diatomite, thiab tseem tuaj yeem txiav ncaj qha los ntawm ntuj sov diatomite. Tab sis feem ntau yog diatomite yog siv los ua cov khoom siv raw, nrog me me ntawm cov av nplaum sib txuas, maj mam muab pov tseg, moulded, moulded. Nws yog ib qho kev siv rwb thaiv rwb rwb thaiv tsev uas nquag siv rau hauv cov khoom muaj cov kilns thiab thipalines thipalines, nrog kev nyab xeeb siv ntsuas kub ntawm 900 degree.
