Ndeapi marudzi e silica alumina refractory zvidhinha zvinosanganisirwa?

(1) Silika zvidhinha: tarisa kune zvidhinha zvinoramba zvine zvinopfuura 293% SiO, uye ndiwo makuru emhando dzeasidhi refractory zvidhinha. Inonyanya kushandiswa kugadzira maovheni ecoke, uye inoshandiswawo kune mavhavha uye zvimwe zvinotakura-zvinotakura zvikamu zvemoto unopisa kune akasiyana girazi, ceramics, carbon calciners, uye zvidhinha zvinoramba. Inoshandiswawo muzvikamu zvepamusoro-soro zvinotakura zvinopisa zvinopisa zvitofu, asi zvisingashandisi mumidziyo inopisa iri pasi pe600 ° C uye nekushanduka kukuru kwekushisa.

(2) Zvidhinha zvevhu: Zvidhinha zvevhu zvinonyanya kuumbwa nemullite (25% -50%), girazi chikamu (25% -60%), cristobalite uye quartz (kusvika ku30%). Kazhinji ivhu rakaoma rinoshandiswa seyakasvibirira, iyo yakura inofanoverengerwa, yozosanganiswa nevhu rakapfava, iro rinoumbwa nehafu-yakaoma kana yepurasitiki nzira, uye tembiricha iri 1300 ~ 1400 C kupisa zvigadzirwa zvevhu. Iwe unogonawo kuwedzera zvishoma zvegirazi remvura, simende uye mamwe mabhanhire kuti uite zvigadzirwa zvisina kupiswa uye amorphous zvinhu. Icho chidhinha chinoramba chinowanzo shandiswa mumoto unoputika, zvitofu zvinopisa, zvitofu zvekudziisa, mabhoiler emagetsi, kilns yeraimu, kilns inotenderera, ceramics uye zvidhinha zvinopisa zvidhinha.

(3) Yakakwira alumina refractory zvidhinha: Iyo mineral inoumbwa yealumina yakakwira zvidhinha inomira ndeye corundum, mullite uye girazi chikamu. Izvo zvirimo zvinoenderana nechiyero che AL2O3 / SiO2 uye rudzi uye huwandu hwetsvina. Izvo zvidhinha zvinoramba zvinogona kuiswa maererano nezviri mukati AL2O3. Izvo zvigadzirwa zvakakwirira alumina bauxite uye sillimanite echisikigo ores, pamwe neayo akasanganiswa neyakasanganiswa corundum, sintered alumina, synthetic mullite, uye clinker calcined nealuminium uye ivhu muzvikamu zvakasiyana. Iyo inonyanya kugadzirwa ne sintering nzira. Asi zvigadzirwa zvinosanganisira zvidhinha zvakasanganiswa, zvidhinha zvezviyo zvakasanganiswa, zvidhinha zvisina kupiswa uye zvidhinha zvisina kuumbwa. High alumina refractory zvidhinha zvinoshandiswa zvakanyanya muindasitiri yesimbi, isiri-ferrous simbi indasitiri uye mamwe maindasitiri.

(4) Corundum refractory zvidhinha: Corundum zvidhinha zvinoreva rudzi rwechidhinha chinoramba chine zviri mukati AL2O3 kwete pasi pe90% uye chikamu chikuru checorundum. Inogona kukamurwa kuita sintered corundum zvidhinha uye yakasanganiswa corundum zvidhinha.
