Clay bonded refractory castable zvakare inonyanya kushandiswa, kunyangwe iyo refractoriness haina kukwirira kupfuura yakakwira aluminium refractory castable, asi mutengo wakachipa, pasi pechiito che sodium hacetaphosphate dispersant uye coagulant, tsvaga kuwana basa rekuvaka, tembiricha uye tembiricha yakaderera. simba. Nokudaro, muvhu-yakasungirirwa refractory castable, iyo chete inoparadzanisa inogona kuparadzira zvizere zvimedu zvevhu kuti kuderedze kuvharwa kwevhu, asi sodium hexametaphosphatine inogona kuita basa rakanaka rekupararira muvhu-yakasungirirwa refractory castable, kuitira kuti ivhu-yakabatanidzwa. refractory castable ine mvura yakanaka uye inovakwa, kuitira kuti ive nechokwadi chekuita kwayo kwakanaka kwekushisa.
The mix ratio of clay refractory castable yakasiyana. Ivhu rakasanganiswa ne refractory castable rine zvakananga index zvinodiwa zvevhu: AL2O3 i29% ~ 35%, Fe2O3 iri pasi pe1.8%, K2O iri pasi pe1.1%, kupisa kunoderedzwa kusvika 10% ~ 14%, refractoriness yakakura kudarika 1670 ℃, uye ine yakafara sintering tembiricha renji, mumineral kuumbwa kunofanirwa kunge kune diki montmorillonite uye mica nezvimwe zvinhu, kuitira kuti ive yakanaka bonding uye plasticity. Inopfuura 60% yevhu inofanira kuva isingasviki 0.088mm mushure mekukuya, uye chiyero chayo 7% -13%.
Refractory aggregate inonyanya kushandisa ivhu clinker uye yakakwira bauxite clinker, yakakura saizi 10mm, general aggregate account yeanenge 70%, yakanaka poda sarudza yakakosha kana A high bauxite clinker yekukuya, dzimwe nguva yakasanganiswa nealuminium poda kana corundum poda, isingasviki 0.088mm maakaunti. kweanopfuura 85%, mune castable 17% ~ 25%.
Kusarudzwa kwakawanda kwearuminiyamu simende yakakwirira kana yakachena calcium simende sechinhu chinoomesa, muyero i 0.2% ~ 3.0%, muvhu colloidal dispersion system, wedzera alkali simbi ions se dispersant, inogona kuumba alkali ion ivhu, nokuti alkali ions ine positivity yakasimba, mutsauko unogona kuitika, simba rinosemesa pakati pevhu revhu. Kune akawanda cations muvhu, uye kupindirana kwezvikamu kunowedzera, izvo zvinosimudzira iyo colloidal gel yevhu, inoburitsa mvura isingabhadharwi, inowedzera fluidity yekukandwa, uye inobatsira kupemha kuumba.
Kuenzaniswa nealuminate simende refractory castable, yakajairika ivhu refractory castable ine hunhu hwesimba repamusoro, hapana kuderera kwesimba pane yepakati tembiricha uye kuramba kune spalling. Kuenzaniswa nepurasitiki, ine hunhu hwekuvakisa kuri nyore uye kuchengetedza nyore. Kupisa kwayo kwekushandisa kunowanzo 1400 -- 1500 ℃.Sodium hexametaphosphate(Hexametaphosphate) yakashandiswa zvakanyanya muvira remoto senge ivhu refractory castable inonyudza choto uye kupisa kwevira.
