Mushonga mukuru wekemikari yemabheji anoyangarara ndiyo oxide yesilicon nealuminium, umo zviri mukati mesilicon dioxide zvinenge 50-65%, uye zviri mukati mealuminium oxide inenge 25-35%.Nekuti nzvimbo yekunyunguduka yesilica yakakwira kusvika 1725 ℃ uye iyo yealumina i2050 ℃, ese ari akakwira refractory zvinhu.Naizvozvo, mabhero anoyangarara ane yakanyanya kurefractoriness, kazhinji anosvika 1600-1700 ℃, achiaita akanakisa epamusoro-kuita refractories.Uremu huremu, kupisa kwemafuta.Mudhuri webead unoyangarara wakatetepa uye hauna mhango, mhango ihafu vacuum, ishoma chete gasi (N2, H2 uye CO2, nezvimwewo), uye kupisa kwemhepo kunononoka uye kudiki kwazvo.Naizvozvo, mabheji anoyangarara haasi kungoita huremu huremu (huremu huremu 250-450 kg / m3), asiwo akanakisa mukupisa kwekushisa (thermal conductivity 0.08-0.1 pakupisa kwekamuri), iyo inoisa hwaro hwekuti vaite basa rakakosha. mumunda wechiedza chekudzivirira kupisa zvinhu.

High kuoma uye simba.Nekuti bhedhi rinoyangarara igomba regirazi rakaoma rakagadzirwa ne silica alumina mineral phase (quartz uye mullite), kuoma kwayo kunogona kusvika kuMohs 6-7, static pressure simba inogona kusvika 70-140mpa, uye density yayo yechokwadi i2.10-2.20g/cm3 , iyo yakaenzana nedombo.Naizvozvo, mabhero anoyangarara ane simba guru.Kazhinji, iwo akareruka porous kana maburi zvinhu senge perlite, dombo rinovira, diatomite, sepiolite uye yakawedzera vermiculite ine hurombo hurema uye simba.Zvigadzirwa zvekupisa zvekupisa kana zvireru zverefractory zvakagadzirwa kubva kwavari zvine dhizaini yekusasimba kwesimba.Kukanganisa kwavo angori masimba emabhero anoyangarara, saka mabhero anoyangarara ane zvakanakira kukwikwidza uye kushandiswa kwakakura.Iyo particle size yakanaka uye iyo chaiyo nzvimbo yakakura.Ukuru hwechisikigo hwemabheji anoyangarara ndeye 1-250 μ M. Iyo chaiyo nzvimbo ndeye 300-360cm2 / g, yakafanana neyesimende.Naizvozvo, mabhero anoyangarara anogona kushandiswa zvakananga pasina kugaya.

Fineness inogona kusangana nezvinodiwa zvezvakasiyana zvigadzirwa, zvimwe zvinyoro zvinyoro zvekudzivirira zvemukati zvinowanzo hombe saizi (senge perlite, nezvimwewo), kana kugaya kuchawedzera zvakanyanya kugona, kuitira kuti kupisa kwemafuta kuderedzwa zvakanyanya.Panyaya iyi, mabhero anoyangarara ane zvakanakira.Yakanakisa magetsi ekudzivirira.Iwo mabhero anoyangarara akanakisa insulating zvinhu uye kwete-conductive.Kazhinji, kuramba kwe insulator kunodzikira nekuwedzera kwekushisa, asi kuramba kwebead inoyangarara kunowedzera nekuwedzera kwekushisa.Iyi bhenefiti haina kune zvimwe insulating zvinhu.Nokudaro, inogona kugadzira zvigadzirwa zvekudzivirira pasi pemamiriro ekupisa kwepamusoro.
