Ukuqaliswa kwe-calcium silicate insulation material

I-calcium silicate (i-microporous calcium silicate) i-insulation material yenziwe nge-silicon dioxide powder material (i-quartz sand powder, umhlaba we-diatomaceous, njl.), i-calcium oxide (ikwaluncedo kwi-glass fiber weft, njl. njl.) njengeyona nto iphambili ekrwada, kwaye emva koko yongeza amanzi , Abancedisi, 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, okuhluke kwizinto ezisetyenziswayo njengemicu eqinisiweyo kunye nezixhobo zokuncedisa i-coagulation, umlinganiselo okanye iimeko zenkqubo yokuvelisa, kunye neemveliso ezibangelwayo Ukubunjwa kweekhemikhali kunye neempawu ezibonakalayo ze-calcium silicate nazo zihluke.

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 zisetyenziswe 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 eyomeleleyo, 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.
