Iyo density range ye calcium silicate material inenge 100-2000kg/m3.Zvigadzirwa zvisingaremi zvakakodzerwa kushandiswa sekudzivirira kana kuzadza zvinhu;zvigadzirwa zvine mwero density (400-1000kg/m3) anonyanya kushandiswa semadziro zvinhu uye refractory kuvhara zvinhu;zvigadzirwa zvine density ye1000kg/m3 uye pamusoro zvinonyanya kushandiswa semadziro emadziro, Kushandisa zvinhu zvepasi kana insulating zvinhu.Kupisa kwekushisa kunonyanya kuenderana nehuwandu hwechigadzirwa, uye inowedzera nekukwira kwekushisa kwemukati.Calcium silicate material ine yakanaka yekudzivirira kupisa uye kugadzikana kwekupisa, uye yakanaka kudzivirira moto.Icho chinhu chisingabatike (GB 8624-1997) uye haizobudisi gasi rine muchetura kana utsi kunyangwe pakupisa kwakanyanya.Muzvirongwa zvekuvaka, calcium silicate inoshandiswa zvakanyanya sechinhu chinoramba chifukidziro chesimbi matanda, makoramu uye madziro.Calcium silicate refractory board inogona kushandiswa semadziro emadziro, yakamiswa sirin'i uye mukati uye kunze kwekushongedza zvinhu mudzimba dzakajairwa, mafekitori nezvimwe zvivakwa uye zvivakwa zvepasi pevhu zvine zvinodiwa nemoto.
Microporous calcium silicate imhando yekupisa yekupisa yakagadzirwa ne siliceous zvinhu, calcium zvinhu, inorganic fiber yakasimbisa zvinhu uye yakawanda yemvura mushure mekusanganisa, kupisa, gelation, kuumba, autoclave kurapa, kuomesa uye mamwe maitiro.Insulation zvinhu, chikamu chayo chikuru hydrated silicic acid uye calcium.Zvinoenderana neyakasiyana hydration zvigadzirwa zvechigadzirwa, inogona kazhinji kukamurwa kuita tobe mullite mhando uye xonotlite mhando.Nekuda kwemhando dzakasiyana dzezvigadzirwa, kusanganisa reshiyo uye mamiriro ekugadzirisa anoshandiswa mazviri, iyo yemuviri uye makemikari zvinhu zve calcium silicate hydrate inogadzirwa zvakasiyana.
Iko kune kunyanya maviri akasiyana marudzi esilicon derivation crystal zvigadzirwa zvinoshandiswa semidziyo yekuisa.Imwe ndeye torbe mullite mhando, chikamu chayo chikuru ndeye 5Ca0.6Si02.5H2 0, tembiricha isingadziviriri i650 ℃;imwe yacho xonotlite mhando, chikamu chayo chikuru 6Ca0.6Si02.H20, inodzivirira kupisa Tembiricha inogona kusvika pa1000°C.
Microporous calcium silicate insulation material ine zvakanakira mwenje wakawanda density, simba rakawanda, yakaderera thermal conductivity, yakanyanya kupisa tembiricha, uye yakanaka kuramba moto.Iyo imhando ye block heat insulation material ine zvirinani kuita.Ndiyo imwe yeanonyanya kushandiswa kupisa kwemafuta ekudzivirira zvinhu mumaindasitiri ekunze, uye nhamba huru yezvigadzirwa zvinogadzirwa uye kushandiswa muChina.
Silica zvinhu zvinhu zvine silicon dioxide sechinhu chikuru, iyo inogona kuita ne calcium hydroxide pasi pemamwe mamiriro ezvinhu kuti igadzire simende inonyanya kuumbwa ne calcium silicate hydrate;calcium zvinhu zvinhu zvine calcium oxide sechinhu chikuru.Mushure me hydration, inogona kuita ne silica kuumba simentitious kunyanya hydrated calcium silicate.Mukugadzira microporous calcium silicate insulation materials, iyo siliceous mbishi zvinhu zvinowanzo shandisa diatomaceous pasi, yakanakisa quartz poda inogonawo kushandiswa, uye bentonite inogonawo kushandiswa;iyo calcium raw materials inowanzo shandisa lime slurry uye slaked lime iyo inogayiwa nebundu lime Powder kana lime paste, tsvina yemumaindasitiri senge calcium carbide slag, nezvimwewo inogona kushandiswawo;asbestos fibers anowanzo shandiswa sekusimbisa mafibhi.Mumakore achangopfuura, mamwe mafibers akadai sealkali-resistant glass fibers uye organic sulfuric acid fibers (senge mapepa emapepa) akashandiswa kusimbisa;Mishonga mikuru inoshandiswa mukugadzirisa ndiyo mvura: girazi, soda ash, aluminium sulfate uye zvichingodaro.
The raw material reshiyo yekugadzirwa kwecalcium silicate inowanzonzi: CaO/Si02=O.8-1.O, mafibers ekusimbisa anoita 3% -15% yehuwandu hwesilicon uye calcium zvinhu, additives account ye5% -lo y6, uye mvura 550% -850%.Kana uchigadzira tobe mullite-type microporous calcium silicate insulation material ine tembiricha isingadziviriri ye650 ℃, iyo mhute pressure inowanzo shandiswa ndeye o.8～1.1MPa, imba yekubatira iri 10h.Paunenge uchigadzira xonotlite-type microporous calcium silicate zvigadzirwa zvine tembiricha isingadziviriri ye1000 ° C, mbishi ine kuchena kwepamusoro inofanira kusarudzwa kugadzira CaO/Si02 =1.O, iyo vapor pressure inosvika 1.5MPa, uye nguva yekubata inosvika kupfuura 20h, ipapo xonotlite-type calcium silicate hydrate crystals inogona kuumbwa.
Calcium silicate board maitiro uye mashandisirwo emhando
Microporous calcium silicate thermal insulation material kunyanya ine maitiro anotevera: kushandiswa kwekushisa kwakakwirira, uye kushandiswa kwekushisa kunogona kusvika 650 ° C (I type) kana 1000 ° C (type II) maererano;②Zvishandiso zvakashandiswa zvinonyanya zvese Iri inorganic material isingapise, uye ndeyeClass A isingabatike zvinhu (GB 8624-1997).Hazvizobudisi gasi rine chepfu kunyange kana moto ukaitika, iyo inobatsira zvikuru kuchengetedza moto;③Kudzikira kwemafuta ekupisa uye kunaka kwekudzivirira ④Kudzikira kwakawanda, kusimba kukuru, kuri nyore kugadzira, kunogona kuchekwa nekucheka, kuri nyore pakuvaka panzvimbo;⑤Kuramba kwakanaka kwemvura, hapana kuora uye kukanganisa mumvura inopisa;⑥Haisi nyore kuchembera, hupenyu hurefu hwebasa;⑦ Inyise mukati Kana iri mumvura, mushonga unobva waita aqueous hauna kwawakarerekera kana kuti hauna kusimba alkaline, saka hauzoparadze midziyo kana mapaipi;⑧Zvigadzirwa zviri nyore kuwana uye mutengo wakachipa.
Nekuti iyo microporous calcium silicate material ine hunhu hwadudzwa pamusoro, kunyanya hwayo hwekupisa kupisa, kusamira kwekushisa, kusapisa, uye kusaburitswa kwegasi rine muchetura, yakashandiswa zvakanyanya mukuvaka mapurojekiti ekudzivirira moto.Parizvino, yakashandiswa zvakanyanya mumaindasitiri akasiyana-siyana akadai sesimbi, indasitiri yemakemikari, simba remagetsi, kuvaka ngarava, kuvaka, etc. Inoshandiswa sechinhu chinopisa chinopisa pamidziyo yakasiyana-siyana, mapaipi uye zvishandiso, uye inewo kudzivirira moto. basa.
