Kachulukidwe kachulukidwe ka calcium silicate zakuthupi ndi pafupifupi 100-2000kg/m3.Zopangira zopepuka ndizoyenera kugwiritsidwa ntchito ngati zotsekemera kapena zodzaza;mankhwala okhala ndi kachulukidwe wapakatikati (400-1000kg/m3) amagwiritsidwa ntchito makamaka ngati zida zapakhoma ndi zida zotchingira zopinga;zopangidwa ndi kachulukidwe 1000kg/m3 ndi pamwamba zimagwiritsa ntchito ngati zipangizo khoma, Kugwiritsa ntchito zipangizo pansi kapena insulating zipangizo.The matenthedwe madutsidwe makamaka zimadalira kachulukidwe mankhwala, ndipo kumawonjezeka ndi kukwera kwa kutentha yozungulira.Calcium silicate zakuthupi zimakhala ndi kutentha kwabwino komanso kukhazikika kwamafuta, komanso kukana moto wabwino.Ndi chinthu chosayaka (GB 8624-1997) ndipo sichidzatulutsa mpweya wapoizoni kapena utsi ngakhale kutentha kwambiri.M'ntchito yomanga, calcium silicate imagwiritsidwa ntchito kwambiri ngati chotchinga chotchinga chazitsulo, mizati ndi makoma.Calcium silicate refractory board itha kugwiritsidwa ntchito ngati khoma pamwamba, denga loyimitsidwa ndi zokongoletsera zamkati ndi zakunja m'nyumba wamba, m'mafakitale ndi nyumba zina ndi nyumba zapansi panthaka zokhala ndi zofunikira zamoto.
Microporous calcium silicate ndi mtundu wa kutchinjiriza kwa matenthedwe opangidwa ndi zida za siliceous, zida za calcium, zida zolimbitsa thupi komanso kuchuluka kwa madzi mutatha kusakaniza, kutentha, gelation, kuumba, kuchiritsa kwa autoclave, kuyanika ndi njira zina.Insulation zakuthupi, chigawo chake chachikulu ndi hydrated silicic acid ndi calcium.Malinga ndi mitundu yosiyanasiyana ya hydration ya mankhwalawa, imatha kugawidwa kukhala mtundu wa tobe mullite ndi mtundu wa xonotlite.Chifukwa cha mitundu yosiyanasiyana ya zida zopangira, kusakanikirana kosakanikirana ndi mikhalidwe yopangira zomwe zimagwiritsidwa ntchito mwa iwo, thupi ndi mankhwala a calcium silicate hydrate opangidwa ndi osiyana.
Pali mitundu iwiri yosiyana ya zinthu za silicon derivation crystal zomwe zimagwiritsidwa ntchito ngati zida zotchinjiriza.Imodzi ndi mtundu wa torbe mullite, chigawo chake chachikulu ndi 5Ca0.6Si02.5H2 0, kutentha zosagwira kutentha ndi 650 ℃;ina ndi xonotlite mtundu, chigawo chake chachikulu ndi 6Ca0.6Si02.H20, yosamva kutentha Kutentha kumatha kufika pa 1000°C.
Microporous calcium silicate insulation material ili ndi ubwino wa kuwala kochuluka, mphamvu zambiri, kutsika kwa matenthedwe, kutentha kwa ntchito, ndi kukana moto wabwino.Ndi mtundu wa block heat insulation material ndi ntchito yabwino.Ndi imodzi mwazinthu zomwe zimagwiritsidwa ntchito kwambiri poteteza kutentha kwamafuta m'mafakitale akunja, ndipo zinthu zambiri zimapangidwa ndikugwiritsidwa ntchito ku China.
Zida za silika ndi zida zokhala ndi silicon dioxide monga chigawo chachikulu, chomwe chingagwirizane ndi calcium hydroxide pansi pazifukwa zina kupanga cementitious makamaka wopangidwa ndi calcium silicate hydrate;zinthu za calcium ndi zinthu zomwe zili ndi calcium oxide monga chigawo chachikulu.Pambuyo pa hydration, imatha kuchitapo kanthu ndi silika kupanga cementitious makamaka hydrated calcium silicate.Popanga microporous calcium silicate kutchinjiriza zipangizo, siliceous zopangira zambiri ntchito diatomaceous lapansi, zabwino kwambiri quartz ufa angagwiritsidwenso ntchito, ndipo bentonite angagwiritsidwenso ntchito;zopangira kashiamu nthawi zambiri amagwiritsa ntchito laimu slurry ndi slaked laimu kuti agayidwe ndi mtanda laimu Ufa kapena laimu phala, zinyalala mafakitale monga kashiamu carbide slag, etc. angagwiritsidwenso ntchito;Ulusi wa asbestos nthawi zambiri umagwiritsidwa ntchito ngati ulusi wolimbitsa.M'zaka zaposachedwa, ulusi wina monga ulusi wagalasi wosamva alkali ndi ulusi wa sulfuric acid (monga ulusi wamapepala) wagwiritsidwa ntchito kulimbikitsa;Zowonjezera zazikulu zomwe zimagwiritsidwa ntchito pokonzekera ndi madzi: galasi, soda phulusa, aluminium sulphate ndi zina zotero.
Chiŵerengero cha zipangizo zopangira calcium silicate nthawi zambiri ndi: CaO/Si02=O.8-1.O, ulusi wolimbitsa umapanga 3% -15% ya kuchuluka kwa silicon ndi calcium, zowonjezera zimawerengera 5% -lo y6, ndi madzi 550% -850%.Popanga tobe mullite-type microporous calcium silicate insulation material ndi kutentha kosagwira kutentha kwa 650 ℃, mphamvu ya nthunzi yomwe imagwiritsidwa ntchito nthawi zambiri ndi o.8 ~ 1.1MPa, chipinda chosungira ndi 10h.Popanga mankhwala opangidwa ndi xonotlite a microporous calcium silicate okhala ndi kutentha kosagwira kutentha kwa 1000 ° C, zopangira zokhala ndi zoyera kwambiri ziyenera kusankhidwa kuti zipange CaO/Si02 =1.O, kuthamanga kwa nthunzi kumafika ku 1.5MPa, ndipo nthawi yogwira imafika kuposa 20h, ndiye kuti xonotlite-mtundu wa calcium silicate hydrate makhiristo amatha kupangidwa.
Makhalidwe a board a calcium silicate ndi osiyanasiyana
Microporous calcium silicate thermal insulation material makamaka ili ndi makhalidwe awa: kutentha kwa ntchito ndipamwamba, ndipo kutentha kwa ntchito kumatha kufika 650 ° C (I mtundu) kapena 1000 ° C (mtundu II) motero;②Zida zopangira zomwe zimagwiritsidwa ntchito ndizo zonse Ndizinthu zopanda organic zomwe siziwotcha, ndipo ndi za Class A zosayaka (GB 8624-1997).Sizidzatulutsa mpweya wapoizoni ngakhale moto ukachitika, zomwe zimapindulitsa kwambiri chitetezo chamoto;③Otsika matenthedwe matenthedwe ndi zabwino kutchinjiriza zotsatira ④Long chochuluka kachulukidwe, mkulu mphamvu, zosavuta pokonza, akhoza macheke ndi kudula, yabwino kumanga pa malo;⑤Kukana madzi abwino, osawola komanso kuwonongeka m'madzi otentha;⑥Zosavuta kukalamba, moyo wautali wautumiki;⑦ Zilowerereni m'madzi, madzi amadzimadzi otuluka m'madzi amakhala osalowerera kapena opanda mchere wamchere, choncho sangawononge zida kapena mapaipi;⑧Zida zopangira ndizosavuta kupeza ndipo mtengo wake ndi wotsika mtengo.
Chifukwa chakuti microporous calcium silicate material ili ndi makhalidwe omwe tawatchula pamwambapa, makamaka kutentha kwake kwapadera, kutentha kwa kutentha, kusayaka, komanso kutulutsa mpweya wa poizoni, wakhala akugwiritsidwa ntchito kwambiri pomanga ntchito zotetezera moto.Pakali pano, wakhala akugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga zitsulo, makampani opanga mankhwala, mphamvu yamagetsi, kumanga zombo, zomangamanga, ndi zina zotero. Amagwiritsidwa ntchito ngati zida zotetezera kutentha pazida zosiyanasiyana, mapaipi ndi zowonjezera, komanso zimakhala ndi chitetezo chamoto. ntchito.
