Calcium silicate board yog ib qho nyuaj, fiber ntau-reinforced microporous thermal rwb thaiv tsev slab tsim los ntawm cov ntaub ntawv siliceous, quicklime, thiab reinforcing fibers ntawm dynamic hydrothermal autoclaving (ua xonotlite thiab tobermorite siv lead ua lattices). Kev xa cov kev pabcuam txuas ntxiv los ntawm 650℃txog 1000℃nrog kev tsim kho qhov ntom ntom ntawm 230 txog 270 kg / m³, qhov rwb thaiv tsev tsis muaj asbestos no ua ke nrog cov thermal conductivity tsawg (0.055-0.095 W / m·K) nrog lub zog compressive siab tshaj 0.65 MPa tsis ua haujlwm.
Tsis zoo li cov ntaub mos mos ceramic fiber ntau uas compressed thiab nyob rau hauv cov khoom siv thauj khoom, cov calcium silicate boards ruaj khov muab cov txheej txheem ruaj khov tom qab ntom ntom refractory cib thiab castables hauv cement rotary kilns, petrochemical heaters, thiab aluminium melting furnaces. Hauv qab no yog cov txheej txheem kev sib txawv ntawm tobermorite (650 degree) thiab xonotlite (1000 degree) qib, compressive cwj pwm, masonry installation xyaum, thiab Hoobkas ncaj qha mus yuav khoom tsis.
Crystal Mineralogy: Tobermorite (650 degree) vs. Xonotlite (1000 degree)
Qhov siab tshaj plaws ua haujlwm kub ntawm lub rooj tsavxwm calcium silicate yog tswj hwm los ntawm nws cov txheej txheem hluavtaws crystalline tsim thaum lub zog siab chav autoclaving:
650℃Medium-Temperature Qib (Tobermorite Lattice):Synthesized ntawm autoclave siab ntawm 0.8 txog 1.2 MPa. Thawj theem ntxhia yog 5CaO·6SiO₂·5H₂O (tobermorite). Qib no yog tsim los rau cov kav dej, lub tshuab hluav taws xob tsim hluav taws xob, thiab hauv cheeb tsam cua sov tes hauj lwm uas qhov ntsuas kub tsis tu ncua qis dua 650 degree. Tshaj 700 degree, tobermorite dehydrates sai, ua rau volumetric shrinkage thiab micro-cracking.
1000℃High-Temperature Qib (Xonotlite Lattice):Autoclaved ntawm lub zog siab dua (1.5 txog 2.0 MPa) thiab tswj Ca / Si molar ratios. Cov qauv siv lead ua tau zoo yog 6CaO·6SiO₂·H₂O (xonotlite). Nrog cov tshuaj chemically khi dej kaw nruj nreem nyob rau hauv koob zoo li interlocking crystals, xonotlite khaws tag nrho ntim stability thiab txhua yam muaj zog mus txog 1000℃yam tsis muaj qhov tseem ceeb shrinkage.
Qhia meej cov khoom muaj ntawv pov thawj ncaj qha los ntawm kev txheeb xyuashigh density calcium silicate board Hoobkasxyuas kom meej tias 1000℃boards yog 100% xonotlite-raws li, tsis txhob ua ntej lub cev qhuav dej shrinkage tom qab lub cub tawg kub-lub ntsej muag linings.

Rigid Calcium Silicate vs. Ceramic Fiber Blanket: Kev xaiv thaub qab
Thaum engineering thaub qab thermal rwb thaiv tsev tom qab hnyav ua hauj lwm hauv ob sab phlu, cov neeg saib xyuas cov nroj tsuag feem ntau hnyav boards tsis yooj yim sua:
Load-Bearing Muaj peev xwm:Nyob rau hauv lub hydrostatic thiab tuag hnyav hnyavkub refractory bricks, hloov tau yooj yim ceramic pam compress los ntawm 30% mus rau 50%, altering tsim hauv ob sab phlu thickness thiab ua rau kub kub. Calcium silicate boards txhawb ntau tshaj 65 metric tons ib square meter (0.65 MPa) nrog qis dua 5% deformation, tswj kev ua haujlwm tsis zoo.
Handling & Machinability:Calcium silicate boards txiav kom huv si nrog cov txheej txheem woodworking tes saws los yog lub rooj saws voj voog uas tsis tsim cov huab cua xoob xoob ua pa. Lawv tuaj yeem ua ntej drilled, routed, thiab zoo li tus ntawm qhov chaw nrog nruj nreem haum.
Vibration & Gas Velocity Resistance:Hauv cov khoom siv vibration siab xws li cement preheater towers thiab rotary kiln hoods, cov pam mos fiber ntau tuaj yeem ntim los yog tawg thaum lub sijhawm. Rigid boards nyob twj ywm mechanically tiv thaiv lub cub tawg steel casing phaj.
Thermal Application Limit:Rau qhov cub kub lub ntsej muag tshaj 1100℃tsis muaj cib cladding, hnyavceramic fiber ntau daim pam rau lub qhov cub hauv ob sab phlulos yog monolithic castables yuav tsum tau xaiv, nrog calcium silicate ua hauj lwm tshwj xeeb tshaj yog nyob rau hauv lub txias backup cheeb tsam.
Muaj kev siv thoob plaws cov nroj tsuag kub
1. Cement Rotary Kiln Systems & Preheater Cyclones
Nyob rau hauv cyclone preheaters, tertiary cua ducts, thiab kiln pa taws chamber, calcium silicate boards ua hauj lwm raws li lub thib ob rwb thaiv tsev txheej ncaj qha tom qab ntom firebricks los yog castables.
Kev teeb tsa installation:50 hli los yog 100 hli 1000℃boards thov tiv thaiv lub plhaub steel, ua raws li los ntawm ib tug ua hauj lwm hauv ob sab phlu.siab alumina castable refractory.
Cov txiaj ntsig:Txo qhov cub steel plhaub kub hauv qab 85 degree, txo cov hluav taws xob hluav taws xob thaum tiv thaiv cov txheej txheem steel los ntawm thermal qaug zog.
2. Petrochemical Reformers & Cracking Rauv
High-density 1000℃boards insulate furnace sidewalls thiab radiant ru tsev qab lub teeb yuag insulating firebricks. Cov tshuaj tsis muaj tshuaj lom neeg siab (pH 9-10) tiv thaiv kev xeb txawm tias cov kua qaub acidic flue gases condense ze ntawm qhov dej lwg.
3. Non-Ferrous Aluminium Melting & Tuav Rauv
Molten aluminium ntawm 750℃tsis ntub lossis nkag mus rau xonotlite-based calcium silicate. High-density boards yog ua hauj lwm raws li tsis-wetting backup khaubncaws sab nraud povtseg qab silicon carbide los yog high-alumina hearth castables, tiv thaiv sab nraud casings thaum lub sij hawm cov hlau nkag.
Kev txhim kho, Txiav & Kev Tiv Thaiv Kev Tiv Thaiv
Txhawm rau kom ua tiav lub neej kev sib tw zoo tshaj plaws thiab tiv thaiv kev sib kis ntawm cov txheej txheem thaum pib tua:
Kev Tiv Thaiv Dej Infiltration:Calcium silicate boards muaj qhib microporosity (tshaj 80% tag nrho cov porosity). Thaum pouring ntub castables ncaj qha rau ntawm lub rooj tsavxwm lub ntsej muag,ib txwm siv cov yeeb yaj kiab yas tsis muaj dej los yog bitumen barrier hla lub rooj tsavxwm. Yog tias tsis kho, lub rooj tsavxwm qhuav yuav rub cov dej tawm ntawm cov castable ntub dej, tiv thaiv kom zoo hydraulic hydration thiab tsis muaj zog castable daim ntawv cog lus.
Staggered Ob-Layer Masonry:Rau rwb thaiv tsev thicknesses ntawm 100 hli los yog ntau tshaj, ib txwm qhia ob 50 hli txheej ntsia nrog staggered kab rov tav thiab ntsug pob qij txha. Qhov kev tsim no tawg ncaj qha thermal txoj hauv kev los ntawm kev sib koom ua ke, tshem tawm los ntawm-thickness tshav kub bridging.
Mechanical Fastening:Fasten boards rau lub cub tawg daim hlau siv stainless hlau pin anchors nrog ceev washers, los yog khi lawv siv matched high-temperature silicate nplaum mortar. Xyuas kom cov sib koom mortar yog thov thinly (hauv qab 2 hli).
