Calcium silicate (microporous calcium silicate) cov khoom siv rwb thaiv tsev yog ua los ntawm silicon dioxide hmoov khoom (quartz xuab zeb hmoov, diatomaceous ntiaj teb, thiab lwm yam), calcium oxide (tseem siv tau rau iav fiber ntau weft, thiab lwm yam) ua cov khoom siv tseem ceeb, thiab tom qab ntawd ntxiv dej, pab, molding, autoclave hardening, ziab thiab lwm yam txheej txheem.Cov ntaub ntawv tseem ceeb ntawm calcium silicate yog lub ntiaj teb diatomaceous thiab txiv qaub los ntawm Shen.Nyob rau hauv qhov kub thiab txias siab, hydrothermal cov tshuaj tiv thaiv tshwm sim, uas yog txawv los ntawm raw cov ntaub ntawv uas siv raws li cov fibers reinforced thiab coagulation pab cov ntaub ntawv, tus piv los yog cov txheej txheem ntau lawm, thiab cov khoom uas tshwm sim cov tshuaj muaj pes tsawg leeg thiab lub cev muaj zog ntawm calcium silicate kuj. txawv.
Calcium silicate siv rau hauv cov ntaub ntawv rwb thaiv tsev muaj ob qhov sib txawv siv lead ua.Calcium silicate yog thawj zaug tsim los ntawm Owence Comeing Glass Fiber Corporation hauv Tebchaws Meskas nyob ib ncig ntawm 1940.Kev sim, cov khoom npe kaylo (kaylo), siv hauv kev lag luam thiab lub tsev rwb thaiv tsev.Txij thaum ntawd los, lub tebchaws United Kingdom, Nyiv, thiab yav dhau los Soviet Union kuj tau tshawb fawb thiab tsim khoom.Ntawm lawv, Nyiv tau tsim sai heev, thiab cov khoom ntim tau poob los ntawm 350kg / m3 mus rau 220kg / m3.Rau cov khoom lag luam tobel mullite uas nws qhov kev pabcuam kub qis dua 650 ℃, Nyiv tau tsim cov khoom siv ultra-lub teeb nrog qhov ceev ntawm 100-130kg / m3.Hauv cov khoom siv thermal rwb thaiv tsev siv hauv kev lag luam thermal rwb thaiv tsev hauv Nyij Pooj, calcium silicate suav txog li 70%.Tebchaws Asmeskas tau tsim muaj zog calcium silicate nrog lub zog flexural> 8MPa, uas yog siv los ua gasket rau cov raj xa dej.
Thaum xyoo 1970, kuv lub teb chaws tau tsim thiab siv tobermorite-type calcium acid thermal rwb thaiv tsev cov khoom hauv qab 650 ° C, thiab siv asbestos ua fiber ntau reinforcing, feem ntau yog molded los ntawm casting, nrog ib tug ceev ntawm 500-1000kg / m.30 Tom qab xyoo 1980, nws tau rov ua dua.Cov txheej txheem yog txheej txheem compression molding, uas txhim kho cov khoom zoo thiab cov tsos zoo ntawm cov khoom thiab txo qhov ceev kom tsawg dua 250kg / m3.Pib tsim cov khoom uas tsis yog asbestos calcium silicate thermal rwb thaiv tsev khoom nyob rau hauv 1 xyoo, thiab pib export ib feem ntawm nws.
Calcium silicate rwb thaiv tsev cov ntaub ntawv tau siv txij li xyoo 1970s txog rau tam sim no.Nyob rau hauv cov nqe lus ntawm molding, nws tau hloov zuj zus los ntawm casting mus rau compression molding;Raws li cov khoom siv, nws tau tsim los ntawm asbestos calcium silicate rau asbestos-dawb calcium silicate;Nyob rau hauv cov nqe lus ntawm kev ua tau zoo, nws tau raug tsim los ntawm dav silicic acid.Calcium tau tsim rau hauv ultra-light calcium silicate thiab muaj zog calcium silicate.Tam sim no, nws yog cov khoom siv thermal rwb thaiv tsev zoo tshaj plaws ntawm cov ntaub ntawv nyuaj.
Tom qab kev tshawb fawb tshawb fawb, cov khoom siv tshwj xeeb kub-resistant nto thiab kub-kub nplaum rau calcium silicate thermal rwb thaiv tsev cov khoom tau ua tiav, thiab lawv tau siv dav, uas daws cov teeb meem uas cov khoom siv calcium silicate tsis tuaj yeem smeared nrog cov ntaub ntawv zoo tib yam.
Cov yam ntxwv ntawm calcium silicate rwb thaiv tsev khoom
Cov khoom yog lub teeb thiab hloov tau, muaj zog corrosion, tsis tshua muaj thermal conductivity, kev pabcuam kub thiab ruaj khov zoo.
Suab rwb thaiv tsev, tsis-combustible, hluav taws-resistant, tsis-corrosive, thiab tsis emit toxic gases thaum siv kub.
Nws muaj kev tiv thaiv tshav kub thiab thermal stability, thiab ruaj khov.
Kev tiv thaiv dej zoo, kev ntub dej mus ntev yuav tsis raug puas tsuaj.
Cov tsos ntawm cov khoom yog zoo nkauj, thiab nws tuaj yeem saws, npaj, drilled, screwed, pleev xim rau, thiab ntsia.Nws yog kev ua haujlwm-txuag thiab yooj yim.
Cov ntaub ntawv saum toj no yog hais txog calcium silicate rwb thaiv tsev cov ntaub ntawv qhia los ntawm Fiber Cement Board Company.
