Kuita kwakanakisa uye kushandiswa kwemabhedhi anoyangarara

High moto resistance.Iyo mikuru yekemikari inoumba mabead anoyangarara maokisisi esilicon nealuminium, nesilicon dioxide inoverengera 50-65% uye aluminium trioxide accounting inosvika 25-35%.Nekuti panonyungudika silicon dioxide yakakwira kusvika 1725 madhigirii celsius, uye nzvimbo yekunyunguduka kwealuminum oxide i2050 madhigirii celsius, ese ari akakwira refractory zvinhu.Naizvozvo, mabhero anoyangarara ane yakanyanya kupisa moto kuramba, kazhinji anosvika 1600-1700 madhigirii Celsius, achiaita akanakisa epamusoro-kuita refractory zvinhu.Lightweight, insulated uye insulated.Mudhuri webhedhi unoyangarara wakatetepa uye une mhango, une semi vacuum mukati megomba uye ishoma chete gasi (N2, H2, CO2, nezvimwewo), zvichikonzera kunonoka uye kushoma kupisa.Saka mabheji anoyangarara haangoreruke chete (ane uremu hwechikamu che250-450 kilograms/m3), asi zvakare ane yakanakisa insulation uye kupisa kwemafuta (ine thermal conductivity ye 0.08-0.1 patembiricha yekamuri), iyo inoisa hwaro hwavo. hukuru hunogoneka mumunda wezvinhu zvireruke zvekudzivirira.High kuoma uye simba.Sezvo bhedhi rinoyangarara riri girazi rakaoma rakagadzirwa nesilicon aluminium Oxide mineral phase (quartz uye mullite), kuoma kwayo kunogona kusvika kuMohs 6-7, static pressure simba inogona kusvika 70-140MPa, uye hukuru hwayo hwechokwadi i2.10-2.20g/cm3 , iyo yakaenzana nedombo.Naizvozvo, mabhero anoyangarara ane simba guru.Kazhinji, zvinyoro zvinyoro kana mhango zvinhu zvakaita sePerlite, dombo rinofashaira, diatomite, pumice, yakawedzera vermiculite, nezvimwe ndezvekusasimba uye kusimba.Zvigadzirwa zvekupisa zvekupisa kana zvireru zverefractory zvakagadzirwa nazvo zvine dhizaini yesimba rakashata.Kushaya simba kwavo ndiko kusimba kwemabhedhi anoyangarara, izvo zvinovapa mukana wekukwikwidza uye huwandu hwakawanda hwekushandisa.Fine particle size uye yakakura chaiyo nzvimbo.Saizi yakasikwa yemabhidhi anoyangarara inotangira pa1 kusvika pa250 microns.Iyo chaiyo nzvimbo ndeye 300-360cm2 / g, iyo yakafanana nesamende.Naizvozvo, mabhero anoyangarara haadi kukuya uye anogona kushandiswa zvakananga.Iyo fineness inogona kusangana nezvinodiwa zvezvakasiyana zvigadzirwa.Zvimwe zviremekedzo zvemafuta ekudzivirira zvinyoro zvinowanzova zvehukuru hukuru (sePerlite).Kana vakakuyiwa, simba richawedzerwa zvikuru uye kupisa kwekushisa kuchaderedzwa zvikuru.Panyaya iyi, mabhero anoyangarara ane zvakanakira.Yakanakisa magetsi ekudzivirira.Iyo bhiza inoyangarara mushure mekusarudza iyo magineti bead chinhu chakanakisa chinodzivirira icho chisingafambisi magetsi.Kupokana kwe general insulators kunodzikira nekuwedzera tembiricha, ukuwo kuramba kwemabhesi anoyangarara kunowedzera nekuwedzera tembiricha.Iyi bhenefiti haina kune zvimwe zvekudzivirira zvinhu.Saka, inogona kushandiswa kugadzira zvigadzirwa zvekudzivirira pasi pemamiriro ekushisa akanyanya.
