Ukuqaliswa kwe-calcium silicate insulation material

I-calcium silicate (microporous calcium silicate) imathiriyeli yokugquma yenziwe ngesilicon dioxide powder material (quartz sand powder, diatomaceous earth, njl.), i-calcium oxide (ikwaluncedo kwi-glass fiber weft, njl. amanzi , Izincedisi, ukubumba, ukuqina kwe-autoclave, ukomisa kunye nezinye iinkqubo.Izinto eziphambili ze-calcium silicate yi-diatomaceous earth kunye ne-lime evela e-Shen.Ngaphantsi kobushushu obuphezulu kunye noxinzelelo oluphezulu, ukusabela kwe-hydrothermal kwenzeka, okwahlukileyo kwizinto ezisetyenziswa njengemicu eqinisiweyo kunye nezixhobo zokuncedisa i-coagulation, umlinganiselo okanye iimeko zenkqubo yokuvelisa, kunye neemveliso ezibangelwayo. ezahlukeneyo.

I-calcium silicate esetyenziswe kwizinto zokugquma inezakhiwo ezimbini ezahlukeneyo zekristale.I-calcium silicate yaqala ukusungulwa ngu-Owence Coming Glass Fiber Corporation e-United States malunga ne-1940.Uvavanyo, igama lemveliso kaylo (kaylo), elisetyenziswa kwimizi-mveliso kunye ne-insulation yokwakha.Ukususela ngoko, iUnited Kingdom, iJapan, nommandla owawusakuba yiSoviet Union nawo aye aqhuba uphando nemveliso.Phakathi kwabo, iJapan iye yaphuhliswa ngokukhawuleza, kwaye ukuxinwa kwemveliso kuye kwehla ukusuka kwi-350kg / m3 ukuya kwi-220kg / m3.Kwiimveliso zohlobo lwe-tobel mullite ubushushu benkonzo yazo bungaphantsi kwama-650 ℃, iJapan iye yavelisa iimveliso ezikhanyayo ezinoxinzelelo lwe-100-130kg/m3.Kwiimveliso zokugquma kwe-thermal ezisetyenziswa kwishishini lokugquma i-thermal eJapan, i-calcium silicate ibalelwa malunga ne-70%.I-United States ivelise amandla aphezulu e-calcium silicate enamandla e-flexural> 8MPa, esetyenziswa njenge-gasket yokumiswa kwemibhobho.
Ekuqaleni kweminyaka yee-1970, ilizwe lam lavelisa kwaye lasebenzisa i-tobermorite-type calcium acid imveliso yokufakelwa kwe-thermal engaphantsi kwe-650 ° C, kwaye yasebenzisa i-asbestos njengefayibha yokuqinisa, ngokuyininzi ibunjwe ngokuphosa, kunye nobuninzi be-500-1000kg / m.30 Emva kweminyaka yee-1980, yaphinda yaphoswa.Indlela yinkqubo yokubumba i-compression, ephucula umgangatho wangaphakathi kunye nokubonakala komgangatho wemveliso kunye nokunciphisa ubuninzi obungaphantsi kwe-250kg / m3.Yaqala imveliso ye-non-asbestos calcium silicate imveliso yokufakelwa kwe-thermal ngonyaka we-1, kwaye yaqala ukuthumela ngaphandle inxalenye yayo.

Izinto zokugquma i-calcium silicate zisetyenziswe ukusukela ngoo-1970 ukuza kuthi ga ngoku.Ngokumalunga nokubumba, kuye kwavela kwi-casting to compression molding;ngokwezinto eziphathekayo, iphuhliswe kwi-asbestos calcium silicate ukuya kwi-asbestos-free calcium silicate;ngokwemigaqo yokusebenza, iye yaphuhliswa kwi-asidi yesilicic ngokubanzi.I-calcium iphuhliselwe kwi-ultra-light calcium silicate kunye ne-high-strength calcium silicate.Okwangoku, yinto efanelekileyo yokufakelwa kwe-thermal phakathi kwezinto ezinzima.

Emva kophando lwezenzululwazi, izinto ezikhethekileyo zokumelana nobushushu kunye ne-adhesive-high-adhesive ye-calcium silicate thermal insulation products ziye zaphuhliswa ngempumelelo, kwaye ziye zasetyenziswa ngokubanzi, ezisombulula ingxaki yokuba iimveliso ze-calcium silicate azikwazi ukuthambisa ngezinto eziqhelekileyo zomhlaba.

Iimpawu ze-calcium silicate insulation material
Iimveliso zilula kwaye ziguquguqukayo, i-corrosion enamandla, i-conductivity ephantsi ye-thermal, ubushushu benkonzo ephezulu kunye nomgangatho ozinzile.
Ukugqunywa kwesandi, okungatshiyo, ukumelana nomlilo, akukhuseli, kwaye akukhuphi iigesi eziyityhefu xa kusetyenziswe kumaqondo obushushu aphezulu.
Inokumelana nokushisa kunye nokuzinza kwe-thermal, kwaye iqinile.
Ukuchasana kwamanzi okulungileyo, ukucwiliswa kwexesha elide akuyi konakaliswa.
Inkangeleko yale mveliso intle, yaye inokusarha, icwangciswe, yolwe, ikrwelwe, ipeyintwe, ize ifakwe.Iyasindisa abasebenzi kwaye iluncedo.
Olu lwazi lungentla lunxulumene ne-calcium silicate insulation materials yaziswa yiFiber Cement Board Company.
