Calcium silicate (microporous calcium silicate) insulation material yakagadzirwa nesilicon dioxide poda zvinhu (quartz jecha poda, diatomaceous earth, etc.), calcium oxide (inobatsirawo kune girazi fiber weft, nezvimwewo) sechinhu chikuru, uye wobva wawedzera. mvura , Auxiliaries, kuumba, autoclave kuomesa, kuomesa uye mamwe maitiro.Izvo zvakakosha zve calcium silicate ndeye diatomaceous pasi uye lime kubva kuShen.Pasi petembiricha yepamusoro uye kumanikidzwa kwakanyanya, hydrothermal reaction inoitika, iyo yakasiyana kubva kune yakabikwa zvinhu zvinoshandiswa seyakasimbiswa fiber uye coagulation aid zvinhu, chiyero kana mamiriro ekugadzira maitiro, uye zvinokonzeresa zvigadzirwa. zvakasiyana.
Calcium silicate inoshandiswa mukudzivirira zvinhu ine maviri akasiyana makristasi zvimiro.Calcium silicate yakatanga kugadzirwa naOwence Coming Glass Fiber Corporation muUnited States makore akapoteredza 1940.Muedzo, zita rechigadzirwa kaylo (kaylo), rinoshandiswa muindasitiri uye kuvaka insulation.Kubva ipapo, United Kingdom, Japan, uye yaimbova Soviet Union dzakaitawo tsvakurudzo uye kugadzira.Pakati pavo, Japan yakakurumidza kukura, uye kuwanda kwechigadzirwa kwakaderera kubva pa350kg/m3 kusvika 220kg/m3.Kune zvigadzirwa zvetobel mullite zvine tembiricha yebasa iri pasi pe650 ℃, Japan yakagadzira zvigadzirwa zvemhando yepamusoro zvine density ye100-130kg/m3.Muchigadzirwa chekupisa chemafuta chinoshandiswa muindasitiri yekupisa yekupisa muJapan, calcium silicate account inoita 70%.United States yakagadzira yakakwirira-simba calcium silicate ine flexural simba> 8MPa, iyo inoshandiswa segasket yekumisa pombi.
Mukutanga kwema1970, nyika yangu yakagadzira uye yakashandisa tobermorite-type calcium acid thermal insulation products pazasi 650 ° C, uye yakashandisa asbestos sefiber inosimbisa, yakanyanya kuumbwa nekukanda, ine density ye500-1000kg/m.30 Mushure memakore ekuma1980, yakadzokororwa.Iyo nzira ndeye compression molding process, iyo inovandudza kunaka kwemukati uye kutaridzika kwemhando yechigadzirwa uye inoderedza density kusvika pasi pe250kg/m3.Yakatanga kugadzirwa kwezvinhu zvisiri-asbestos calcium silicate thermal insulation products mugore 1, ndokutanga kutengesa kunze kwenyika chikamu chayo.
Calcium silicate insulation material yakashandiswa kubva kuma1970 kusvika nhasi.Panyaya yekuumbwa, yakashanduka kubva pakukandira kusvika pakumanikidza kuumbwa;maererano nezvinhu, yakagadzirwa kubva ku asbestos calcium silicate kusvika kune asbestos-isina calcium silicate;maererano nekuita, yakagadziridzwa kubva kune general sililic acid.Calcium yakagadziridzwa kuita ultra-light calcium silicate uye yakakwirira-simba calcium silicate.Parizvino, ndiyo yakanakira kupisa kwemafuta mukati memidziyo yakaoma.
Mushure mekutsvagisa kwesainzi, iyo yakakosha inodzivirira tembiricha yepamusoro uye yakanyanya-tembiricha inonamira yecalcium silicate thermal insulation zvigadzirwa zvakabudirira kugadzirwa, uye zvakashandiswa zvakanyanya, izvo zvinogadzirisa dambudziko rekuti calcium silicate zvigadzirwa hazvigone kuzorwa nezvinhu zvakajairika zvepasi.
Hunhu hwe calcium silicate insulation material
Zvigadzirwa zvakareruka uye zvinochinjika, corrosion yakasimba, low thermal conductivity, tembiricha yepamusoro yebasa uye yakagadzikana mhando.
Kuvharidzirwa kwenzwi, kusingabatike, kusingadziviriki, kusaodza, uye hakubudisi magasi ane muchetura kana akashandiswa pakupisa kwakanyanya.
Inopikisa kupisa uye kugadzikana kwekushisa, uye inogara kwenguva refu.
Kuramba kwakanaka kwemvura, kunyura kwenguva refu hakuzokuvadzwa.
Chimiro chechigadzirwa chacho chakanaka, uye chinogona kuchekwa, kurongwa, kuboorwa, kukwizwa, kupendwa, uye kuiswa.Inochengetedza basa uye yakanakira.
Ruzivo rwuri pamusoro rwune chekuita necalcium silicate insulation zvinhu zvakaunzwa neFiber Cement Board Company.
