Ibanga lokuminyana le-calcium silicate material lilinganiselwa ku-100-2000kg/m3.Imikhiqizo engasindi ifanele ukusetshenziswa njenge-insulation noma izinto zokugcwalisa;imikhiqizo ene-medium density (400-1000kg/m3) isetshenziswa kakhulu njengezinto zodonga kanye nezinto zokumboza eziphikisayo;imikhiqizo enomthamo we-1000kg/m3 nangaphezulu isetshenziswa kakhulu njengezinto zodonga, Ukusetshenziswa kwezinto eziphansi noma izinto zokuvikela.I-conductivity eshisayo incike ikakhulukazi ekumineni komkhiqizo, futhi iyanda ngokukhuphuka kwezinga lokushisa elizungezile.I-calcium silicate impahla inokumelana nokushisa okuhle nokuzinza kokushisa, nokumelana nomlilo okuhle.Kuyinto engashi (GB 8624-1997) futhi ngeke ikhiqize igesi enobuthi noma intuthu ngisho namazinga okushisa aphezulu.Emisebenzini yokwakha, i-calcium silicate isetshenziswa kabanzi njengento yokumboza ephikisayo yemishayo yesakhiwo sensimbi, amakholomu nezindonga.Ibhodi le-calcium silicate refractory lingasetshenziswa njengendawo yodonga, uphahla olumisiwe kanye nezinto zokuhlobisa zangaphakathi nezangaphandle ezindlini ezijwayelekile, amafekthri nezinye izakhiwo kanye nezakhiwo ezingaphansi komhlaba ezinezidingo zokuvikela umlilo.
I-Microporous calcium silicate iwuhlobo lwe-thermal insulation eyenziwe ngezinto ze-siliceous, izinto ze-calcium, izinto eziqinisiwe ze-fiber ye-inorganic kanye nenani elikhulu lamanzi ngemuva kokuxuba, ukushisa, i-gelation, ukubumba, ukuphulukiswa kwe-autoclave, ukomisa nezinye izinqubo.I-insulation material, ingxenye yayo eyinhloko i-hydrated silicic acid ne-calcium.Ngokwemikhiqizo ehlukene ye-hydration yomkhiqizo, ngokuvamile ingahlukaniswa ngohlobo lwe-tobe mullite kanye nohlobo lwe-xonotlite.Ngenxa yezinhlobo ezahlukene zezinto zokusetshenziswa, izilinganiso zokuxuba kanye nezimo zokucubungula ezisetshenziswa kuzo, izakhiwo zomzimba nezamakhemikhali ze-calcium silicate hydrate ezikhiqizwayo nazo zihlukile.
Kunezinhlobo ezimbili ezihlukene kakhulu zemikhiqizo ye-silicon derivation crystal esetshenziswa njengezinto zokufakelwa.Olunye uhlobo lwe-torbe mullite, ingxenye yalo eyinhloko i-5Ca0.6Si02.5H2 0, izinga lokushisa elimelana nokushisa ngu-650 ℃;enye iwuhlobo lwe-xonotlite, ingxenye yalo eyinhloko i-6Ca0.6Si02.H20, ukumelana nokushisa Izinga lokushisa lingaba phezulu njengo-1000°C.
I-Microporous calcium silicate insulation material inezinzuzo zokuminyana kwenqwaba yokukhanya, amandla aphezulu, ukuqhutshwa kokushisa okuphansi, izinga lokushisa eliphezulu lokusetshenziswa, nokumelana nomlilo okuhle.Kuwuhlobo lwe-block heat insulation material esebenza kangcono.Ingenye yezinto ezisetshenziswa kakhulu zokufaka ukushisa okushisayo ezimbonini zaphesheya, futhi inani elikhulu lemikhiqizo likhiqizwa futhi lisetshenziswe eChina.
Izinto ze-silica ziyizinto ezine-silicon dioxide njengengxenye eyinhloko, engasabela nge-calcium hydroxide ngaphansi kwezimo ezithile ukuze yenze i-cementitious ikakhulukazi eyakhiwe nge-calcium silicate hydrate;izinto ze-calcium ziyizinto ezine-calcium oxide njengengxenye eyinhloko.Ngemuva kokufakwa kwe-hydration, ingasabela nge-silica ukwenza i-cementitious ikakhulukazi i-hydrated calcium silicate.Ekwenziweni kwezinto zokufakelwa kwe-calcium silicate microporous, izinto zokusetshenziswa kwe-siliceous ngokuvamile zisebenzisa umhlaba we-diatomaceous, i-quartz powder enhle kakhulu ingasetshenziswa, futhi i-bentonite nayo ingasetshenziswa;izinto zokusetshenziswa ze-calcium ngokuvamile zisebenzisa i-lime slurry kanye ne-lime e-slaked egaywe yisigaxa se-lime I-powder noma i-lime paste, udoti wezimboni njenge-calcium carbide slag, njll.Imicu ye-asbestos ngokuvamile isetshenziswa njengemicu yokuqinisa.Eminyakeni yamuva, eminye imicu efana ne-alkali-resistant glass fibers kanye ne-organic sulfuric acid fibers (njengemicu yephepha) iye yasetshenziselwa ukuqinisa;Izithasiselo eziyinhloko ezisetshenziswa kule nqubo ngamanzi: ingilazi, i-soda ash, i-aluminium sulfate nokunye.
Isilinganiso sempahla eluhlaza yokukhiqizwa kwe-calcium silicate ngokuvamile ithi: CaO/Si02=O.8-1.O, i-reinforcing fibers ihlanganisa u-3% -15% yenani eliphelele le-silicon ne-calcium, izithasiselo zibalelwa ku-5% -lo y6, futhi amanzi 550% -850%.Lapho ukhiqiza i-tobe mullite-type microporous calcium silicate insulation material enezinga lokushisa elimelana nokushisa elingu-650 ℃, umfutho womhwamuko ovame ukusetshenziswa ngu-o.8～1.1MPa, igumbi lokubamba liyi-10h.Lapho ukhiqiza imikhiqizo ye-xonotlite-microporous calcium silicate enezinga lokushisa elimelana nokushisa elingu-1000°C, izinto zokusetshenziswa ezinobumsulwa obuphakeme kufanele zikhethwe ukwenza i-CaO/Si02 =1.O, umfutho we-vapor ufinyelela ku-1.5MPa, futhi isikhathi sokubamba sifinyelela ngaphezu kwe-20h, khona-ke amakristalu e-xonotlite-calcium silicate hydrate angakhiwa.
Izici zebhodi le-calcium silicate kanye nebanga lesicelo
I-Microporous calcium silicate thermal insulation material ikakhulukazi inezici ezilandelayo: izinga lokushisa lokusetshenziswa liphezulu, futhi izinga lokushisa lokusetshenziswa lingafinyelela ku-650 ° C (I type) noma 1000 ° C (uhlobo II) ngokulandelana;②Izinto ezisetshenziswayo ezisetshenziswayo ziyikho konke Kuyi-inorganic material engashi, futhi ingeyeClass A engashi (GB 8624-1997).Ngeke ikhiqize igesi enobuthi ngisho nalapho kuvela umlilo, okuzuzisa kakhulu ukuphepha komlilo;③I-thermal conductivity ephansi kanye nomthelela omuhle wokwahlukanisa ④Ukuminyana kwenqwaba ephansi, amandla aphezulu, kulula ukucutshungulwa, kungasanwa futhi kusikwe, kulungele ukwakhiwa endaweni;⑤Ukumelana namanzi okuhle, akukho ukubola nokulimala emanzini ashisayo;⑥Akulula ukuguga, impilo ende yesevisi;⑦ Yicwilise Uma isemanzini, isixazululo samanzi esiwumphumela asithathi hlangothi noma sine-alkaline ebuthakathaka, ngakho-ke ngeke kulimaze okokusebenza noma amapayipi;⑧Izinto zokusetshenziswa zitholakala kalula futhi intengo ishibhile.
Ngenxa yokuthi i-microporous calcium silicate material inezici ezibalwe ngenhla, ikakhulukazi ukushisa kwayo okuvelele, ukumelana nokushisa, ukungashi, futhi akukho ukukhishwa kwegesi enobuthi, iye yasetshenziswa kabanzi ekwakheni amaphrojekthi okuvikela umlilo.Njengamanje, isetshenziswe kabanzi ezimbonini ezihlukahlukene ezifana ne-metallurgy, imboni yamakhemikhali, amandla kagesi, ukwakhiwa kwemikhumbi, ukwakhiwa, njll. Isetshenziswa njengento yokufaka ukushisa okushisayo kumishini ehlukahlukene, amapayipi kanye nezesekeli, futhi inokuvikela umlilo. umsebenzi.
