Calcium silicate (microporous calcium silicate) insulation material e entsoe ka silicon dioxide powder material (quartz sand powder, diatomaceous earth, joalo-joalo), calcium oxide (hape e thusa bakeng sa khalase ea fiber weft, joalo-joalo) e le thepa e ka sehloohong e tala, ebe o eketsa metsi , Lisebelisoa, ho bōpa, ho thatafatsa autoclave, ho omisa le mekhoa e meng.Lisebelisoa tse ka sehloohong tsa calcium silicate ke diatomaceous earth le lime ho tloha Shen.Tlas'a mocheso o phahameng le khatello e phahameng, karabelo ea hydrothermal e etsahala, e fapaneng le lisebelisoa tse tala tse sebelisoang e le likhoele tse matlafalitsoeng le lisebelisoa tsa thuso ea coagulation, karo-karolelano kapa maemo a ts'ebetso ea tlhahiso, le lihlahisoa tse hlahisoang. fapaneng.
Calcium silicate e sebelisoang linthong tsa ho kenya letsoho e na le likarolo tse peli tse fapaneng tsa kristale.Calcium silicate e ile ea qaptjoa ka lekhetlo la pele ke Owence Coming Glass Fiber Corporation United States hoo e ka bang ka 1940.Teko, lebitso la sehlahisoa kaylo (kaylo), le sebelisitsoeng ho liindasteri le moaho.Ho tloha ka nako eo, United Kingdom, Japane, le seo pele e neng e le Soviet Union le tsona li entse lipatlisiso le tlhahiso.Har'a bona, Japane e tsoetse pele ka potlako, 'me boima ba lihlahisoa bo theohile ho tloha ho 350kg / m3 ho ea ho 220kg / m3.Bakeng sa lihlahisoa tsa mofuta oa tobel mullite tseo mocheso oa tsona oa litšebeletso o leng ka tlase ho 650 ℃, Japane e hlahisitse lihlahisoa tse khanyang haholo tse nang le boima ba 100-130kg/m3.Lihlahisoang tsa ho kenya letsoho ho futhumatsang tse sebelisoang indastering ea ho futhumatsa mocheso Japane, silicate ea calcium e etsa karolo ea 70%.United States e hlahisitse silicate ea matla a phahameng a calcium e nang le matla a feto-fetohang> 8MPa, e sebelisoang joalo ka gasket bakeng sa ho emisoa ha lipeipi.
Mathoasong a lilemo tsa bo-1970, naha ea heso e ile ea hlahisa le ho sebelisa lihlahisoa tsa ho futhumatsa mocheso oa mofuta oa tobermorite-calcium acid ka tlase ho 650 ° C, 'me e sebelisa asbestos e le fiber e matlafatsang, haholo-holo e bōpiloeng ka ho lahla, e nang le boima ba 500-1000kg / m.30 Kamora lilemo tsa bo-1980, e ile ea fetoloa.Mokhoa ona ke mokhoa oa ho bopa ha compression, o ntlafatsang boleng ba ka hare le boleng ba ponahalo ea sehlahisoa le ho fokotsa boima ba 'mele ho ea ho 250kg / m3.E qalile ho hlahisa lihlahisoa tse se nang asbestos calcium silicate tse futhumatsang mocheso ka selemo sa 1, mme ea qala ho romella karolo ea eona kantle ho naha.
Lisebelisoa tsa tšepe tsa calcium silicate li 'nile tsa sebelisoa ho tloha lilemong tsa bo-1970 ho fihlela joale.Mabapi le ho bopa, e fetohile ho tloha ho lahla ho ea ho compression molding;mabapi le thepa, e tsoetse pele ho tloha ho asbestos calcium silicate ho ea ho asbestos-free calcium silicate;mabapi le ts'ebetso, e entsoe ho tloha ho silicic acid e akaretsang.Calcium e fetohile ultra-light calcium silicate le high-power calcium silicate.Hajoale, ke sesebelisoa se setle sa ho kenya mocheso har'a lisebelisoa tse thata.
Ka mor'a lipatlisiso tsa saense, lisebelisoa tse khethehileng tsa holim'a mocheso le sekhomaretsi se nang le mocheso o phahameng bakeng sa lihlahisoa tsa "calcium silicate thermal insulation" li 'nile tsa ntlafatsoa ka katleho,' me li 'nile tsa sebelisoa haholo, tse rarollang bothata ba hore lihlahisoa tsa calcium silicate li ke ke tsa tlotsoa ka lisebelisoa tse tloaelehileng tsa holim'a metsi.
Litšobotsi tsa thepa ea insulation ea calcium silicate
Lihlahisoa li bobebe ebile lia fetoha, li na le kutu e matla, conductivity e tlaase ea mocheso, mocheso o phahameng oa tšebeletso le boleng bo tsitsitseng.
Molumo oa molumo, o sa cheng, o thibelang mollo, o sa cheng, 'me ha o ntše likhase tse chefo ha o sebelisoa mochesong o phahameng.
E na le ho hanyetsa mocheso le botsitso ba mocheso, 'me e tšoarella nako e telele.
Ho hanyetsa metsi hantle, ho koloba ka nako e telele ho ke ke ha senyeha.
Ponahalo ea sehlahisoa e ntle, 'me e ka sakha, ea raloa, ea phunngoa, ea phunyeletsoa, ea penta le ho kenngoa.E boloka mosebetsi ebile e bonolo.
Tlhahisoleseding e ka hodimo e amana le disebediswa tse entsweng ka calcium silicate tse hlahisitsweng ke Fiber Cement Board Company.
