Calcium silicate yeeb rwb thaiv tsevPuas yog qhov tsis haum, hluav taws kub cov khoom siv thermal rwb thaiv tsev tshwj xeeb tsim los qhwv kav, ducts, thiab lwm yam cylindrical nto. Nws yog engineered los ntawm sib tov ntawmCalcium silicate(Ib qho compound tsim los ntawm calcium oxide thiab silica), txhawb nqa cov pob txha, lossis hluavtaws hluavtaws), thiab cov khoom siv hluav taws xob), thiab cov ntaub ntawv. Qhov kev sib xyaw no tsim cov ntaub ntawv ntom ntom, cov khoom siv ruaj khov uas zoo nyob rau hauv ib puag ncig kub thaum tswj cov qauv txheej txheem kev ntseeg.
Tsis zoo li ua npuas ncauj-raws li cov rwb thaiv tsev lossis cov lus qhia txog cov tshuaj lom neeg lossis muaj cov tshuaj lom neeg, thiab thermal drift (poob ntawm rwb thaiv tsev kev ua haujlwm nyob rau lub sijhawm). Nws ib txwm ua ntej tshaj tawm hauv ntu cylindrical, lub tes tsho, lossis cov laug cam, ua rau nws yooj yim rau nruab ib puag ncig cov kav dej ntawm kev sib txawv.
Txhawm rau kom nkag siab nws cov haujlwm, cia tshawb nws cov ntsiab lus tseem ceeb:
Dab tsi teev cov tshuaj calcium silicate sib cais los ntawm lwm cov ntaub ntawv rwb thaiv tsev? Ntawm no yog nws txhais nta:
Calcium silicate tuaj yeem tiv kev khiav mus tas li kub txog650 ° C (1,200 ° F)Thiab lub sijhawm luv luv raug mus txog 1,000 ° C (1,832 ° F). Qhov no ua rau nws zoo tagnrho rau cov ntawv thov kub xws li cov kav dej sov chav, boiler kab, thiab cov txheej txheem cua sov.
Nrog lub thermal conductivity (K-tus nqi) tsawg li0.045-0.065 W / (MIS.Ntawm 100 ° C, nws me me txo cov cua sov los yog nce. Piv txwv li, insulating li 50mm-lub taub ntim nrog cov calcium silicate tuaj yeem txo cov kav dej kub, cov nqi qis dua.
Txwv raws liA1 tsis-sib txuasNyob rau hauv EN 13501-1 (European cov txheej txheem rau kev faib tawm hauv hluav taws), nws tsis hlawv lossis pab txhawb cov nplaim hluav taws. Qhov no yog qhov tseem ceeb rau cov chaw tua hluav taws uas zoo li cov nroj tsuag hluav taws xob, cov tshuaj ntsuab, thiab cov tshuab hvac.
Tsis zoo li ua npuas ncauj lossis kev sib cais cellulose, calcium sithate yog inherently dej-repellent (tshwj xeeb yog thaum kho nrog hydrophobic additives). Nws tiv thaiv kev nqus noo, kev tiv thaiv pwm kev loj hlob, yeeb nkab corrosion, thiab teeb meem tsis muaj kev tiv thaiv (E.G., cov raj ntug dej hiav txwv).
Nrog kev teeb tsa kom zoo, calcium silicate rwb thaiv tsev kav ntev20-30 xyoos(Lossis ntev dua), outperforming luv luv cov ntaub ntawv xws li ua npuas ncauj (10-15 xyoo) lossis fiberglass (15-20 xyoos). Nws lub durability txo cov nqi kho thiab hloov tus nqi nyob rau lub sijhawm.
Txhawm rau txiav txim siab seb cov tshuaj si calcium yog txoj kev xaiv zoo, nws muaj txiaj ntsig los sib piv nws nrog cov kev xaiv:
| Khoom | Max temp | Kev Ntsuas Hluav Taws | Ya raws tsis kam | Kev muaj peev xwm |
|---|---|---|---|---|
| Calcium silicate | Txog li 650 ° C | A1 tsis-sib txuas | Zoo tshaj | 20-30 + xyoo |
| Iav yas | Txog li 400 ° C | Chav Kawm B (combustible) | Pluag (nqus dej noo) | 10-15 XYOO |
| Ua npuas ncauj (piv txwv li, xps / eps) | Txog li 75 ° C | Chav Kawm B-C | Mob siab (tsis sib haum nrog noo noo) | 5-10 xyoo |
| Cov ntaub plaub av | Txog li 700 ° C | Hoob A1-A2 | Zoo (tab sis tsis tshua muaj zog) | 15-25 xyoos |
Raws li lub rooj qhia, calcium silicate kev ua tau zoo siab, hluav taws kub kev nyab xeeb, thiab noo noo tsis zoo dua li cov kev xaiv ntau dua.
Muab nws cov khoom siv khov kho, calcium cov rwb thaiv tsev ntxaij yog siv thoob plaws kev lag luam sib txawv:
Kev txiav txim hluav taws xob, cov khoom siv tshuaj, thiab cov chaw ua khoom noj kom ruaj khov rau cov dej ntws siab, cov kua dej khov, lossis cov khoom siv rhaw. Cacium silicate lub peev xwm los lis huab cua sov thiab tiv taus corrosion ua rau insulating insulating burter dej fe txwv mis, chav mains, thiab txheej txheem txheej txheem.
Cua sov, dim pa, thiab cua txias tshuab siv cov kav dej kom faib cov dej kub / / dej txias lossis dej txias. Calcium sithulates cov dej ntws txias (tiv thaiv hws thiab pwm) thiab cov dej kub txo qis hauv cov chaw nyob, ua lag luam, lossis cov tsev lag luam).
Cov cua kub tob hauv cov huab cua txias (piv txwv li cov huab cua txias (piv txwv li, Scandinavia, Canada) yuav tsum rwb thaiv tsev uas tiv thaiv hauv av. Calcium silicate lub noo noo tsis kam thiab qhov chaw-ua tau zoo rigid daim ntawv ua kom nws zoo meej rau cov kav dej insulating nyob hauv nroog loj.
Cov kais dej sprinkle, cov khoom muag, thiab cov pa yeeb ntxig xav tau rwb thaiv tsev uas tsis muaj cua sov. Calcium silicate qhov tsis daws teeb meem cov kab ke no ua haujlwm ua haujlwm thaum muaj xwm txheej kub ntxhov, ua raws li cov hluav taws kub zoo li NFPA 25.
Thaum lub teeb tsa kev tsim tawm tau pom zoo, ntawm no yog qhov ceev faj ceev ntawm cov txheej txheem:
Calcium silicate yeeb rwb thaiv tsevyog deb tshaj li ib qho "kub blocker" -it ib qho tseem ceeb heev hauv lub zog-txuag, muaj kev nyab xeeb thiab siv tau ruaj khov. Los ntawm kev sib txuas nrog kev tiv thaiv kub, hluav taws kub kev nyab xeeb, thiab noo noo tsis kam, nws outperforms kev ua ntaub ntawv rwb thaiv tsev hauv cov ntawv thov nkag.
