I-calcium silicate (microporous calcium silicate) insulation material yenziwe nge-silicon dioxide powder material (quartz sand powder, diatomaceous earth, njll.), i-calcium oxide (iwusizo futhi ku-glass fiber weft, njll.) njengento eluhlaza, bese wengeza amanzi , Izinsiza, ukubumba, ukuqina kwe-autoclave, ukomisa nezinye izinqubo.Izinto eziyinhloko ze-calcium silicate yi-diatomaceous earth kanye ne-lime evela e-Shen.Ngaphansi kwezinga lokushisa eliphezulu nokucindezela okuphezulu, ukusabela kwe-hydrothermal kwenzeka, okuhlukile ezintweni zokusetshenziswa ezisetshenziswa njengemicu eqinisiwe kanye nezinto zokusiza ukuhlangana, isilinganiso noma izimo zenqubo yokukhiqiza, kanye nemikhiqizo ewumphumela Ukwakheka kwamakhemikhali kanye nezakhiwo zomzimba ze-calcium silicate nazo. ezahlukene.
I-calcium silicate esetshenziswa ezintweni zokufakelwa inezinhlaka ezimbili ezihlukene zekristalu.I-calcium silicate yaqala ukusungulwa yi-Owence Coming Glass Fiber Corporation e-United States cishe ngo-1940.Isivivinyo, igama lomkhiqizo elithi kaylo (kaylo), elisetshenziswa ekwakhiweni kwezimboni nezakhiwo.Kusukela ngaleso sikhathi, i-United Kingdom, Japan, kanye nezwe elaliyiSoviet Union baye benza ucwaningo nokukhiqiza.Phakathi kwazo, iJapane ithuthuke ngokushesha, futhi ukuminyana komkhiqizo kwehle kusuka ku-350kg/m3 kuya ku-220kg/m3.Ngemikhiqizo yohlobo lwe-tobel mullite izinga lokushisa layo lesevisi lingaphansi kuka-650 ℃, i-Japan ikhiqize imikhiqizo ekhanyayo kakhulu enobukhulu obungu-100-130kg/m3.Emikhiqizweni yokufakwa kwe-thermal esetshenziswa embonini yokufaka ukushisa okushisayo e-Japan, i-calcium silicate yenza cishe ama-70%.I-United States ikhiqize i-calcium silicate enamandla amakhulu enamandla aguquguqukayo> 8MPa, esetshenziswa njenge-gasket yokumiswa kwamapayipi.
Ekuqaleni kwawo-1970, izwe lami lakhiqiza futhi lasebenzisa imikhiqizo yokushisa eshisayo yohlobo lwe-tobermorite-calcium acid engaphansi kuka-650°C, futhi lasebenzisa i-asbestos njengefayibha eqinisayo, ikakhulukazi ebunjwe ngokusakazwa, enobukhulu obungu-500-1000kg/m.30 Ngemva kweminyaka yawo-1980, yaphindwa.Indlela iyinqubo yokubumba yokucindezela, ethuthukisa ikhwalithi yangaphakathi kanye nekhwalithi yokubukeka yomkhiqizo futhi inciphisa ukuminyana ibe ngaphansi kuka-250kg/m3.Iqale ukukhiqizwa kwemikhiqizo ye-non-asbestos calcium silicate efaka ukushisa okushisayo ngonyaka ongu-1, futhi yaqala ukuthumela ngaphandle ingxenye yayo.
I-calcium silicate insulation material ibisetshenziswa kusukela ngeminyaka yawo-1970s kuze kube manje.Mayelana nokubunjwa, kuye kwavela ekubunjweni kuya ekubunjweni kokucindezela;ngokwezinto ezibonakalayo, ithuthukile isuka ku-asbestos calcium silicate yaya ku-asbestos-free calcium silicate;mayelana nokusebenza, yenziwe nge-asilicic acid evamile.I-calcium ithuthuke yaba yi-ultra-light calcium silicate kanye ne-high-strength calcium silicate.Njengamanje, iyinto efanelekile yokufakwa kwe-thermal phakathi kwezinto eziqinile.
Ngemuva kocwaningo lwesayensi, izinto ezikhethekile ezingaphansi kwezinga lokushisa kanye ne-adhesive high-temperature ye-calcium silicate thermal insulation products iye yathuthukiswa ngempumelelo, futhi iye yasetshenziswa kabanzi, okuxazulula inkinga yokuthi imikhiqizo ye-calcium silicate ayikwazi ukugcotshwa ngezinto ezijwayelekile ezingaphezulu.
Izici ze-calcium silicate insulation material
Imikhiqizo ilula futhi iyavumelana nezimo, ukugqwala okuqinile, ukuguquguquka okuphansi kwe-thermal, izinga lokushisa eliphezulu lenkonzo kanye nekhwalithi ezinzile.
Ukufakwa komsindo, okungashi, ukumelana nomlilo, akugqwali, futhi akukhiphi amagesi anobuthi uma kusetshenziswa emazingeni okushisa aphezulu.
Inokumelana nokushisa kanye nokuzinza kokushisa, futhi ihlala isikhathi eside.
Ukumelana kahle kwamanzi, ukucwiliswa kwamanzi isikhathi eside ngeke konakaliswe.
Ukubukeka komkhiqizo muhle, futhi ungasaha, uhlelwe, ubhojwe, ugoqwe, upende futhi ufakwe.Kuyawonga futhi kuwusizo.
Ulwazi olungenhla luhlobene nezinto zokufakwa kwe-calcium silicate ezethulwe yi-Fiber Cement Board Company.
