Ubucucike bwibintu bya calcium silicike hafi ya 100-2000kg / m3.Ibicuruzwa byoroheje bikwiriye gukoreshwa nkibikoresho cyangwa kuzuza ibikoresho;ibicuruzwa bifite ubucucike buciriritse (400-1000kg / m3) bikoreshwa cyane nkibikoresho byurukuta nibikoresho bitwikiriye;ibicuruzwa bifite ubucucike bwa 1000kg / m3 no hejuru bikoreshwa cyane cyane nkibikoresho byo kurukuta, Gukoresha ibikoresho byubutaka cyangwa ibikoresho byo kubika.Amashanyarazi yumuriro ahanini aterwa nubucucike bwibicuruzwa, kandi byiyongera hamwe no kuzamuka kwubushyuhe bwibidukikije.Kalisiyumu silikatike ifite ubukana bwiza nubushyuhe bwumuriro, hamwe no kurwanya umuriro.Nibikoresho bidashya (GB 8624-1997) kandi ntibishobora kubyara gaze uburozi cyangwa umwotsi nubwo haba hari ubushyuhe bwinshi.Mu mishinga yubwubatsi, calcium silicike ikoreshwa cyane nkibikoresho bitwikiriye ibikoresho byubaka ibyuma, inkingi ninkuta.Ikibaho cya Kalisiyumu silikatike irashobora gukoreshwa nkubuso bwurukuta, igisenge cyahagaritswe hamwe nimbere hamwe nibikoresho byo gushariza hanze mumazu asanzwe, inganda nizindi nyubako hamwe ninyubako zo munsi y'ubutaka zisabwa umuriro.
Microporome calcium silikatike ni ubwoko bwimikorere yubushyuhe bukozwe mubikoresho bya silice, ibikoresho bya calcium, fibre organique fibre ibikoresho byongerewe imbaraga hamwe namazi menshi nyuma yo kuvanga, gushyushya, gelation, kubumba, gukiza autoclave, gukama nibindi bikorwa.Ibikoresho byo kubika ibintu, ibyingenzi byingenzi ni hydratike ya silicic aside na calcium.Ukurikije ibicuruzwa bitandukanye biva mu bicuruzwa, birashobora kugabanywa muburyo bwa tobe mullite nubwoko bwa xonotlite.Kubera ubwoko butandukanye bwibikoresho fatizo, kuvanga ibipimo nuburyo bwo gutunganya bikoreshwa muri byo, imiterere yumubiri na chimique ya calcium silicate hydrate yakozwe nayo iratandukanye.
Hariho ubwoko bubiri butandukanye bwa silicon derivation progaramu ya kristu ikoreshwa nkibikoresho byo kubika.Imwe ni ubwoko bwa torbe mullite, ibyingenzi byingenzi ni 5Ca0.6Si02.5H2 0, ubushyuhe burwanya ubushyuhe ni 650 ℃;ikindi ni ubwoko bwa xonotlite, ibyingenzi byingenzi ni 6Ca0.6Si02.H20, irwanya ubushyuhe Ubushyuhe burashobora kuba hejuru ya 1000 ° C.
Microporome calcium silicate ibikoresho byo kubika bifite ibyiza byo kuba urumuri rwinshi, imbaraga nyinshi, ubushyuhe buke bwumuriro, ubushyuhe bwinshi bwo gukoresha, hamwe no kurwanya umuriro.Nubwoko bwo guhagarika ubushyuhe bwimikorere hamwe nibikorwa byiza.Nibimwe mubikoresho bikoreshwa cyane mumashanyarazi mu nganda zo hanze, kandi ibicuruzwa byinshi bikorerwa kandi bigakoreshwa mubushinwa.
Ibikoresho bya Silica ni ibikoresho bifite dioxyde ya silicon nkibice byingenzi, bishobora gukora hamwe na hydroxide ya calcium mubihe bimwe na bimwe kugirango ikore simaitima igizwe ahanini na calcium silike hydrata;ibikoresho bya calcium nibikoresho hamwe na calcium oxyde nkibice byingenzi.Nyuma yo kuyobya amazi, irashobora kwitwara hamwe na silika kugirango ikore simaitima cyane ya calcium silisiyumu.Mu gukora ibikoresho bya microporome calcium silicate insulasiyo, ibikoresho bibisi bya silice bikoresha isi ya diatomaceous, ifu ya quartz nziza cyane nayo irashobora gukoreshwa, kandi bentonite nayo irashobora gukoreshwa;ibikoresho fatizo bya calcium muri rusange bikoresha lime slurry na lime yatonywe bigogorwa na lime lime Powder cyangwa paste lime, imyanda yinganda nka calcium karbide slag, nibindi nabyo birashobora gukoreshwa;fibre ya asibesitosi isanzwe ikoreshwa nkibishimangira fibre.Mu myaka yashize, izindi fibre nka fibre idashobora kwihanganira ibirahuri hamwe na fibre acide sulfurique (nka fibre fibre) byakoreshejwe mugukomeza;Ibyingenzi byingenzi bikoreshwa muribikorwa ni amazi: ikirahure, ivu rya soda, sulfate ya aluminium nibindi.
Ikigereranyo cyibikoresho fatizo byo gukora calcium silisike ni rusange: CaO / Si02 = O.8-1.O, fibre ishimangira ingana na 3% -15% yumubare wuzuye wibikoresho bya silicon na calcium, inyongera zingana na 5% -lo y6, namazi 550% -850%.Iyo utanga tobe mullite yo mu bwoko bwa microporome calcium silikatike yububiko hamwe nubushyuhe bwa 650-, ubushyuhe bwumuyaga bukoreshwa ni o.8 ～ 1.1MPa, icyumba cyo gufata ni 10h.Mugihe utanga umusaruro wa xonotlite wo mu bwoko bwa calcium silicike ya silicike hamwe nubushyuhe butarwanya ubushyuhe bwa 1000 ° C, ibikoresho fatizo bifite isuku nyinshi bigomba gutoranywa kugirango CaO / Si02 = 1.O, umuvuduko wumuyaga ugera kuri 1.5MPa, naho igihe cyo gufata kigera kuri 20h, hanyuma xonotlite yo mu bwoko bwa calcium silicat hydrata kristal irashobora gushirwaho.
Kalisiyumu silikate yibiranga nibisabwa
Microporome calcium silikatike yubushyuhe bwumuriro cyane cyane ifite ibintu bikurikira: ubushyuhe bwo gukoresha buri hejuru, kandi ubushyuhe bwo gukoresha burashobora kugera kuri 650 ° C (Ubwoko bwa I) cyangwa 1000 ° C (ubwoko bwa II);MaterialsIbikoresho fatizo bikoreshwa ni byose ni Byose ni ibintu bidasanzwe bidatwika, kandi ni ibyiciro byo mu cyiciro cya A bidashya (GB 8624-1997).Ntabwo izabyara gaze uburozi niyo habaye umuriro, ifitiye akamaro kanini umutekano;③Gabanya ubushyuhe bwumuriro ningaruka nziza zo gukingira ④Gabanya ubwinshi bwinshi, imbaraga nyinshi, byoroshye gutunganya, birashobora kuboneka no gukata, byoroshye kubakwa;Resistance Kurwanya amazi meza, nta kubora no kwangirika mumazi ashyushye;OtNtabwo byoroshye gusaza, igihe kirekire cyo gukora;AkByinjize Iyo mumazi, igisubizo cyamazi yavuyemo ntaho kibogamiye cyangwa alkaline nkeya, ntabwo rero ishobora kwangiriza ibikoresho cyangwa imiyoboro;MaterialsIbikoresho fatizo biroroshye kubona kandi igiciro kirahendutse.
Kuberako ibikoresho bya microporome calcium silikatike bifite ibimenyetso byavuzwe haruguru, cyane cyane kubika ubushyuhe budasanzwe, kurwanya ubushyuhe, kudashya, no kutarekura gaze uburozi, byakoreshejwe cyane mukubaka imishinga yo gukingira umuriro.Kugeza ubu, yakoreshejwe cyane mu nganda zitandukanye nka metallurgie, inganda z’imiti, ingufu z’amashanyarazi, kubaka ubwato, ubwubatsi, n’ibindi. Ikoreshwa nkibikoresho byo gutwika amashyuza ku bikoresho bitandukanye, imiyoboro n'ibikoresho, kandi ifite no kurinda umuriro imikorere.
