Calcium silicate (microporous calcium silicate) kutchinjiriza zakuthupi amapangidwa ndi pakachitsulo woipa ufa zinthu (quartz mchenga ufa, diatomaceous lapansi, etc.), calcium okusayidi (komanso zothandiza galasi CHIKWANGWANI weft, etc.) monga zopangira chachikulu, ndiyeno kuwonjezera madzi , Zothandizira, akamaumba, autoclave kuumitsa, kuyanika ndi njira zina.Zida zazikulu za calcium silicate ndi nthaka ya diatomaceous ndi laimu wochokera ku Shen.Pansi pa kutentha kwambiri komanso kupanikizika kwambiri, hydrothermal reaction imachitika, yomwe imakhala yosiyana ndi zida zomwe zimagwiritsidwa ntchito ngati ulusi wolimbitsa ndi zida zothandizira, chiŵerengero kapena momwe zinthu zimapangidwira, komanso zotsatira zake. zosiyana.
Calcium silicate yomwe imagwiritsidwa ntchito pazida zotsekemera imakhala ndi mitundu iwiri yosiyana ya kristalo.Calcium silicate inayamba kupangidwa ndi Owence Coming Glass Fiber Corporation ku United States cha m'ma 1940.Mayesero, dzina lazinthu kaylo (kaylo), lomwe limagwiritsidwa ntchito pomanga mafakitale ndi zomanga.Kuyambira pamenepo, United Kingdom, Japan, ndi dziko lomwe kale linali Soviet Union achitanso kafukufuku ndi kupanga.Pakati pawo, Japan yakula mofulumira, ndipo kachulukidwe ka mankhwala atsika kuchokera 350kg/m3 kufika 220kg/m3.Pazinthu zamtundu wa tobel mullite zomwe kutentha kwautumiki kuli pansi pa 650 ℃, Japan yapanga zinthu zowala kwambiri zokhala ndi kachulukidwe ka 100-130kg/m3.Pazinthu zotchinjiriza zomwe zimagwiritsidwa ntchito m'makampani opanga matenthedwe ku Japan, calcium silicate imakhala pafupifupi 70%.United States yapanga silicate yamphamvu kwambiri ya calcium yokhala ndi flexural mphamvu> 8MPa, yomwe imagwiritsidwa ntchito ngati gasket kuyimitsidwa kwa mapaipi.
Kumayambiriro kwa zaka za m'ma 1970, dziko langa linapanga ndi kugwiritsa ntchito mankhwala otsekemera a tobermorite-mtundu wa calcium acid pansi pa 650 ° C, ndipo amagwiritsa ntchito asibesitosi monga chiwombankhanga, makamaka chopangidwa ndi kuponyera, ndi kachulukidwe ka 500-1000kg / m.30 Pambuyo pa zaka za m'ma 1980, idasinthidwanso.Njirayi ndi njira yopangira psinjika, yomwe imapangitsa kuti mkati mwake mukhale ndi maonekedwe abwino komanso amachepetsa kachulukidwe kukhala osachepera 250kg/m3.Anayamba kupanga zinthu zopanda asbestos calcium silicate kutchinjiriza matenthedwe mu chaka chimodzi, ndipo anayamba kutumiza kunja mbali yake.
Calcium silicate insulation material yakhala ikugwiritsidwa ntchito kuyambira 1970s mpaka pano.Ponena za kuumba, zasintha kuchokera ku kuponyera kupita ku kukangana;ponena za zinthu zakuthupi, zapangidwa kuchokera ku asbestos calcium silicate kupita ku silicate ya kashiamu yopanda asbestos;potengera magwiridwe antchito, adapangidwa kuchokera ku silicic acid.Calcium yasanduka ultra-light calcium silicate ndi high-mphamvu calcium silicate.Pakalipano, ndi chinthu chabwino chotetezera kutentha pakati pa zipangizo zolimba.
Pambuyo pa kafukufuku wa sayansi, zida zapadera zosagwirizana ndi kutentha kwapamwamba komanso zomatira zotentha kwambiri za calcium silicate zosungunulira mafuta zapangidwa bwino, ndipo zakhala zikugwiritsidwa ntchito kwambiri, zomwe zimathetsa vuto loti mankhwala a calcium silicate sangathe kupakidwa ndi zinthu wamba pamwamba.
Makhalidwe a calcium silicate insulation material
Zogulitsazo ndi zopepuka komanso zosinthika, zowonongeka zamphamvu, kutsika kwamafuta otsika, kutentha kwambiri kwautumiki komanso khalidwe lokhazikika.
Kutsekereza mawu, osayaka, kukana moto, kosawononga, komanso sikutulutsa mpweya wapoizoni ukagwiritsidwa ntchito pa kutentha kwakukulu.
Ili ndi kukana kutentha ndi kukhazikika kwa kutentha, ndipo imakhala yolimba.
Kukana madzi abwino, kuthira madzi kwa nthawi yayitali sikudzawonongeka.
Maonekedwe a chinthucho ndi okongola, ndipo amatha kuchekedwa, kukonzedwa, kubowola, kupukuta, kupenta, ndi kuyikapo.Ndizopulumutsa antchito komanso zothandiza.
Zomwe zili pamwambazi zikukhudzana ndi zida zotchinjiriza za calcium silicate zomwe zidayambitsidwa ndi Fiber Cement Board Company.
