Calcium silate board
Calcium siry rwb thaiv tsev cov khoom yog ua los ntawm diaomite thiab txiv qaub ua cov khoom siv rawically tseem yog hu ua calcium sicium calcium silicate board.
Calcium Silate rwb thaiv tsev muaj cov khoom ntom nti xws li tsis tshua muaj zog, siab thermal conductivity, yooj yim siv tau thiab poob qis tus nqi.
Qhov ntom ntawm cov bacium Silate Board yog feem ntau cov thwj txwv tsis pub tshaj li 14 {{{{{{{{{{{{{15} 0 kg / m *; Tuam Tshoj tau muab cais ua tsis ntau tshaj 240 kg / m ', tsis muaj ntau tshaj 220kg / m', thiab tsis muaj ntau tshaj 170 kg / m *. Nws lub zog compressive yog saum 0.4mpa, thiab nws lub zog flexural yog saum 0.2mpa; Nws cov thermal conductivity (70 degree ± 5 degree) yog 0.049 ~ 0.064w / (mk). Qhov nyiaj ntau tshaj plaws yog 650 degree rau cov towbmorite thiab 1000 degree rau cov calcium silicate silicate.
Txheej txheem tsim cov calcium silication rwb thaiv tsev cov khoom siv cov qauv cua sov (tseem muaj cov txheej txheem cua sov ( Cov ntaub ntawv nyoos muaj xws li cov khoom siv raw cov zaub mov, calcium raw cov ntaub ntawv, txhawb nqa cov khoom siv thiab ntxiv.
Cov khoom lag luam
Cov ntaub ntawv siliabous raw ntawm calcium Silate rwb thaiv tsev cov khoom yog feem ntau diatomaceous ntiaj teb. Lub ntiaj teb diatomaceous muaj lub ntsej muag ntxig, lub ntom ntom me me, thiab thaj chaw tshwj xeeb thaj tsam. Nws yog qhov pom kev zoo tshaj plaws ntawm cov ntaub ntawv nyoos muaj siio2. Lub Sio2 muaj nyob rau hauv nws lub diatom plhaub yog amorphous thiab yooj yim reacts nrog txiv qaub hauv dej sov hauv qab 100 degree los ua ib qho colloid. Bentonite, cov av nplaum sib dhos, cov hmoov av tshauv, tsis tau, quartz hmoov, thiab lwm yam. Cov khoom siv raw calcium yog tsuas yog txiv qaub. Nws cov ntsiab lus CAO zoo yuav tsum nyob hauv thaj tsam ntawm 73% mus rau 92%. Nws yog qhov zoo tshaj plaws los siv txiv qaub nrog cov ntsiab lus zoo ntawm tsis tsawg tshaj li 85%. Fresh txiv qaub yog zom rau cov txiv qaub slurry nrog dej. Nws lub cao particle loj yog tsawg dua 1μm, uas tsis tsuas yog muaj cov khoom zoo tshem tawm, tab sis kuj yooj yim adheres rau saum npoo ntawm Sio2 hais. Maas tuaj yeem siv hloov ntawm txiv qaub.
Kev txhawb nqa cov hmoov av yuav tsum muaj qhov zoo dispersibility, alkali tsis kam, kub tsis kam thiab muaj affinity nrog lub matrix. Nruab nrab-ntshiab brucite fiber ntau yog qhov tshwj xeeb rau Tuam Tshoj thiab yog cov pa roj carbonate fucking uas tsis muaj mob rau tib neeg lub cev. Organic fibers siv los hloov asbestos suav nrog pulp, femplequen, calcium silicate hmoov thiab silioft silicate hmoov thiab sitrafine hmoov ua li nucleation ntau yam, thiab Lub luag haujlwm ntawm polyacrylamide yog: ua ntej, nws txhawb nqa kev sib xyaw ua ke los tsim cov qauv molecular ua ke los ua tus qauv network, nws tuaj yeem ua lub luag haujlwm txhawb nqa.
Daim ntawv thov calcium Silate rwb thaiv tsev cov khoom lag luam tuaj yeem pom lossis muab ntsia hlau, thiab tuaj yeem ua rau cov paib xws li, thaiv lossis txhais tes lossis cov tes tsho. Lawv tau siv los ua cov ntaub ntawv rwb thaiv tsev rau thipalines thiab muaj cov kilns hauv lub hwj chim, tshuaj lom neeg, metallurgy, thiab cov nkoj; Fireproof thiab rwb thaiv tsev kom sov rau cov tsev thiab khoom siv, thiab tseem siv tau ua cov khaubncaws sab nraud povtseg rau qhov ntsuas kub thiab txias cov khoom siv tsheb; Ob sab ntawm Calcium Silate Mas Muas tau muab cov yas dai kom zoo nkauj, thiab lwm yam kev ua kom zoo nkauj thiab tuaj yeem siv ua lub suab rwb thaiv tsev cov ntaub ntawv. Feem ntau ntawm cov rwb thaiv tsev engineering hauv ntiaj teb siv calcium silicate laug cam. Hauv qee lub tebchaws, 70% rau 80% ntawm kev muaj kev lag luam rwb thaiv tsev siv calcium silicate laug cam.
Calcium siry rwb thaiv tsev cov rwb thaiv tsev yog cov uas tsis yog-uas tsis muaj kuab, tsis muaj tshuaj lom, tsis muaj ntxhiab, lub teeb, thiab muaj zog. Lawv tau raug txheeb xyuas los ntawm thoob ntiaj teb pej xeem pej xeem txoj cai lij choj raws li cov ntaub ntawv tsim nyog rau dej hiav txwv nkoj.
Qhov nyiaj siab tshaj plaws ntawm 1000 degree calcium Silate rwb thaiv tsev cov khoom yog 1000 degree. Nyob rau hauv kev ua lag luam tam sim no, lawv tseem hu ua kev kub calcium calcium silicate rwb thaiv tsev cov khoom. Cov theem tseem ceeb yog cov tawv calcium silicate silicate pob zeb. Peb lub tuam txhab cov khoom muaj plaub lub ntsiab hluav taws xob tawm: ultra-densication ntho thaiv cov khoom muaj tsawg dua 220, muaj ntau hom kev sib cais ntawm cov khoom siv regicate tsawg dua 500 kg / m3.
