Ib tsob ntoo cement hauv Egypt tau xajcalcium silicate boardrau lawv cov preheater ntauwd rwb thaiv tsev xyoo tas los. Cov spec hu rau qib 650 degree, 250 kg/m³, 50mm thickness - ib yam khoom txheem. Tus neeg muag khoom xa khoom raws li tau txiav txim. Rau lub hlis tom qab, pab neeg saib xyuas tau qhib qhov kev tshuaj xyuas thiab pom tias lub rooj tsavxwm tau poob qis thiab tawg, rub tawm ntawm cov thauj tog rau nkoj. Qhov kub thiab txias ntawm ntu ntawd tau khiav mus ze rau 700℃thaum lub sijhawm ua haujlwm siab tshaj plaws vim yog qhov chaw nyias nyias hauv cov castable hauv qab nws. Tsis muaj leej twg tau suav rau qhov chaw kub, thiab 650℃board tsuas yog ua haujlwm dhau qhov txwv.
Calcium silicate board yog cov khoom ncaj nraim ntawm daim ntawv. Hauv kev xyaum, qhov sib txawv ntawm lub rooj tsavxwm uas kav ntev txog kaum xyoo thiab ib qho uas ua tsis tiav hauv ob los txog seb puas yog qib zoo sib xws rau qhov kev pabcuam tiag tiag - tsis yog qhov nominal spec. Phau ntawv qhia no hais txog yuav ua li cas thiaj ua tau qhov sib tw.
650℃vs 1050 degree: Thaum Txhua Qib Ua Kom Zoo
Calcium silicate board tuaj nyob rau hauv ob lub ntsiab qhov kub thiab txias, thiab qhov kev xaiv tsis yog tsuas yog "muab lub qhov cub kub."
650℃qib (Type I)yog tus txheej txheem kev lag luam rwb thaiv tsev board. Nws yog sib dua, raug nqi tsawg dua, thiab npog feem ntau ntawm cov ntawv thov: cov yeeb nkab rwb thaiv tsev, cov rwb thaiv tsev boiler casing, thaub qab board tom qab refractory linings, thiab cov thermal teeb meem uas qhov kub ntawm lub ntsej muag kub nyob qis dua 650℃. Feem ntau cov chav dej thiab cov kav dej kub rwb thaiv tsev siv cov qib no.
Qib 1050℃(Hom II)- qee zaum hu ua siab -kub calcium silicate los yog refractory- qib calcium silicate - siv cov qauv hloov kho uas tiv thaiv qhov ntsws ntawm qhov kub siab dua. Nws tau teev tseg rau cov ntawv thov uas lub rooj tsavxwm zaum ncaj nraim tom qab nyias nyias cov khoom kub- lub ntsej muag hauv ob sab phlu lossis qhov chaw kub kub tuaj yeem thawb qhov kub tshaj 650℃. Cement preheater towers, aluminium rauv rov qab hauv ob sab phlu, thiab incinerator thib ob chambers yog cov kev siv ntau.
Ntawm no yog lub ntsiab lus tseem ceeb uas ntau tus neeg yuav khoom tsis nco: qhov ntsuas kub yog rau lub rooj tsavxwm qhov kub thiab txias tsis tu ncua, tsis yog lub qhov cub ua haujlwm kub. Yog tias lub cub tawg khiav ntawm 900℃tab sis lub rooj tsavxwm zaum tom qab 100 hli castable hauv ob sab phlu uas poob qhov txias -lub ntsej muag kub mus rau 550 degree, ces 650℃yog zoo. Tab sis yog tias cov ntaub ntawv thins hauv zos - lossis yog tias lub rooj tsavxwm siv los ua cov khoom kub - ntsej muag nws tus kheej - siv qib 1050 degree.
| Khoom | Qib 650 degree | Qib 1050 degree |
|---|---|---|
| Max kev pab temp | 650 degree | 1050 degree |
| Hom ntom ntom | 200-250 kg / m³ | 250-300 kg / m³ |
| Thermal conductivity ntawm 200 degree | ~0.06 W/m·K | ~0.07 W/m·K |
| Compressive zog | Ntau dua lossis sib npaug li 1.5 MPa | Ntau dua lossis sib npaug li 2.0 MPa |
| Linear shrinkage ntawm max temp | Tsawg dua lossis sib npaug li 2.0% | Tsawg dua lossis sib npaug li 2.0% |
| Kev sib piv nqi | Lub hauv paus | 15-25% hwm |
Ceev: Siab dua tsis yog ib txwm zoo dua
Calcium silicate board ntom ntom ntawm 200 txog 300 kg / m³ hauv cov qib txheem. Higher density gives better compressive strength, which matters if the board will carry any mechanical load. Tab sis nws kuj nce thermal conductivity me ntsis - vim tias cov khoom siv denser ua kom sov ntau dua - thiab ntxiv qhov hnyav rau kev teeb tsa.
Rau feem ntau cov ntaub ntawv rwb thaiv tsev, 220-250 kg / m³ yog qhov chaw qab zib. Nws muab lub zog txaus los tiv thaiv kev puas tsuaj thiab thauj tog rau nkoj compression yam tsis ntxiv qhov hnyav lossis nqi. Mus rau 280-300 kg / m³ tsuas yog thaum lub rooj tsavxwm yuav tsum tau taug kev thaum saib xyuas lossis thaum muaj zog compressive siab.
Cov Lus Nug Asbestos: Ib txwm nug kom muaj ntawv pov thawj
Calcium silicate board tsim ua ntej xyoo 1980s qee zaum muaj asbestos fibers ua qhov txhawb nqa. Niaj hnub nimno calcium silicate board los ntawm reputable manufacturers yog asbestos -dawb, siv cellulose los yog hluavtaws fiber reinforcement hloov. Tab sis thaum nrhiav los ntawm cov neeg xa khoom tshiab lossis tsis paub txog - tshwj xeeb tshaj yog nyob rau hauv kev lag luam uas cov kev cai tsis nruj me ntsis - tsis xav.
Nug kom sau asbestos- ntawv pov thawj pub dawb. Daim ntawv pov thawj yuav tsum hais txog tus qauv xeem (feem ntau ISO 22262 lossis sib npaug) thiab muab los ntawm peb tus neeg lees paub -lab, tsis yog cov chaw tsim khoom cov lus sab hauv. Ntau qhov kev qhia tshwj xeeb tam sim no xav tau qhov no raws li qhov yuav tsum tau xa tawm, thiab rau qhov laj thawj zoo - kev lav phib xaub ntawm kev txhim kho asbestos- muaj cov khoom siv hauv cov chaw tsim khoom niaj hnub no tsis tsim nyog noj.
Standard Board vs Custom Shaped Parts
Pav ca calcium silicate board nyob rau hauv tus qauv qhov ntau thiab tsawg - feem ntau 1000 × 500mm los yog 1200 × 600mm, thickness ntawm 25mm mus rau 100mm - npog feem ntau daim ntaub ntawv. Rau cov yeeb nkab rwb thaiv tsev, lub rooj tsavxwm raug txiav rau hauv ntu lossis ua ntej- tsim rau hauv cov kav dej los ntawm cov chaw tsim khoom.
Cov ntawv thov nyuaj dua siv cov khoom siv calcium silicate zoo li tus: kev cai- cov khoom siv nrog lub qhov rau cov qhov cub tawg, cov ntu nkhaus rau lub plhaub plhaub, lossis cov vuas sib txuas rau thaj chaw loj. Cov khoom seem raug nqi ntau dua ib chav tab sis txuag kev ua haujlwm vim tias kev txiav thiab kev sib dhos ua tiav ntawm lub Hoobkas es tsis yog ntawm scaffolding.
Yog tias koj qhov project muaj ntau tshaj 20 daim uas xav tau kev txiav ntawm qhov chaw, nug txog lub Hoobkas ua ntej- txiav. Tus nqi sib txawv feem ntau yog offset los ntawm kev txo lub sij hawm installation, thiab lub Hoobkas - txiav qhov chaw muaj nruj dua qhov ntev ntawm daim teb - txiav daim.
Dab tsi los kuaj ua ntej xaj
Txheeb xyuas qhov ntsuas kub nrog koj qhov txias tiag tiag - lub ntsej muag suav.Tsis txhob cia li siv lub cub tawg lub npe phaj kub. Xam qhov kub poob thoob plaws qhov kub - lub ntsej muag hauv ob sab phlu ntawm nws qhov thinnest point - feem ntau ntawm cov ces kaum, nkag mus, los yog qhov chaw paub hnav - thiab xyuas kom lub rooj tsavxwm raug ntsuas rau qhov kub thiab txias ntxiv rau 50℃kev nyab xeeb margin.
Paub meej tias lub rooj tsavxwm hom ntawv.Loj - cov ntaub ntawv hom (1200 × 600mm) npog thaj tsam sai dua tab sis hnyav dua. Cov laug cam me me (600 × 300mm lossis 500 × 250mm) yooj yim rau nruab rau hauv qhov chaw nruj tab sis tsim cov pob qij txha ntau dua.
Npaj rau kev txuas.Calcium silicate board feem ntau txuas nrog stainless hlau studs thiab ntxhua khaub ncaws, los yog nrog siab -kub nplaum rau qis - daim ntawv thov kub. Txoj kev txuas yuav tsum tau teev tseg ua ntej lub rooj tsavxwm thickness tiav, vim tias lub rooj tsavxwm thicker yuav tsum tau ntev dua studs.
Nug txog kev tiv thaiv noo noo.Standard calcium silicate board absorbs ya raws yog raug los nag los yog high humidity thaum lub sij hawm cia. Qee cov tuam txhab lag luam muab cov dej- tshuaj tiv thaiv rau sab nraum zoov cia lossis kev teeb tsa uas lub rooj tsav xwm yuav raug nthuav tawm ua ntej cov txheej txheej sab nrauv mus. Yog tias koj qhov chaw ua haujlwm nyob hauv thaj chaw ntub dej hiav txwv lossis muaj lub caij los nag thaum lub sij hawm tsim kho, qhia lub rooj kho mob lossis npaj rau kev them nyiaj.
Tau txais Lub Rooj Tswjhwm Zoo rau Koj Qhov Haujlwm
Plaub daim ntaub ntawv uas tus neeg muag khoom xav tau: kev khiav hauj lwm kub ntawm lub rooj tsavxwm qhov chaw (tsis yog lub qhov cub kub), yuav tsum tau rwb thaiv tsev thickness, seb lub rooj tsavxwm nqa ib tug neeg kho tshuab load, thiab txoj kev txuas. Nrog rau cov no, lawv tuaj yeem pom zoo qib thiab qhov ntom ntom hauv ib qho lus teb.
