Drift bead rudzi rwebhora rine hollow ash rinogona kuyerera pamusoro pemvura. Rine ruvara rwegrey chena, rine madziro matete uye asina chinhu, uye huremu hwaro hwakareruka. Huremu hweyuniti i720kg/m3 (hunorema), 418.8kg/m3 (hwakareruka), uye saizi ye particle inenge 0.1mm. Pamusoro paro pakavharwa uye pakanyatsotsvedzerera, rine thermal conductivity yakaderera uye resistance yemoto ye ≥ 1610 ℃. Ichinhu chakanakisa chinodzivirira tembiricha, chinoshandiswa zvakanyanya mukugadzira castables dzakareruka uye kuchera mafuta. Kuumbwa kwemakemikari efloating bead kunonyanya kuve silicon dioxide nealuminium oxide. Rine hunhu hwe fine particles, hollow, light huremu, high strength, wear resistance, high tembiricha resistance, thermal insulation, insulation uye fire retardancy. Ndiro rimwe rezvinhu zvinoshandiswa zvakanyanya muindasitiri yefire resistance.

Kushanda kwakanaka uye kushandiswa kwemabheya anoyangarara

Kudzivirira moto zvakanyanya. Zvikamu zvikuru zvemakemikari emabhandi anoyangarara ioxides yesilicon nealuminium, silicon dioxide inosvika 50-65% uye aluminium trioxide inosvika 25-35%. Nekuti nzvimbo yekunyunguduka yesilicon dioxide inosvika 1725 degrees Celsius, uye nzvimbo yekunyunguduka yealuminium oxide inosvika 2050 degrees Celsius, ese ari maviri ari zvinhu zvinoramba kupisa zvakanyanya. Nokudaro, mabhindi anoyangarara ane simba guru rekudzivirira moto, anowanzosvika 1600-1700 degrees Celsius, zvichiita kuti ave zvinhu zvakanaka zvinoramba kupisa. Zvishoma, zvinodzivirira kupisa uye zvinodzivirira kupisa. Madziro emabhindi anoyangarara akatetepa uye asina chinhu, ane semi vacuum mukati megomba uye gasi diki chete (N2, H2, CO2, nezvimwewo), zvichikonzera kupisa kunonoka uye kushoma. Saka mabhora anoyangarara haasi ekureruka chete (ane huremu hweyuniti ye250-450 kg/m3), asiwo ane insulation yakanaka uye insulation yekupisa (ine thermal conductivity ye0.08-0.1 patembiricha yemumba), izvo zvinoisa hwaro hwekugona kwawo kukuru mumunda wezvinhu zvekudzivirira zvakareruka. Kuomarara kwakanyanya uye simba. Sezvo bead rinoyangarara riri girazi rakaoma rakaumbwa nesilicon aluminum Oxide mineral phase (quartz ne mullite), kuomarara kwaro kunogona kusvika Mohs 6-7, simba rekumanikidza rinomira rinogona kusvika 70-140MPa, uye density yaro chaiyo i2.10-2.20g/cm3, iyo yakaenzana neyedombo. Naizvozvo, mabhora anoyangarara ane simba guru. Kazhinji, zvinhu zvine maburi madiki kana maburi zvakaita sePerlite, boiling rock, diatomite, pumice, expanded vermiculite, nezvimwewo hazvina kuomarara uye simba. Zvigadzirwa zve insulation yekupisa kana zvigadzirwa zvinoramba chiedza zvakagadzirwa nazvo zvine dambudziko resimba risinganyanyi kusimba. Kusasimba kwavo ndiko kusimba kwemabhora anoyangarara, izvo zvinovapa mukana wekukwikwidzana uye kushandiswa kwakasiyana-siyana. Saizi yezvikamu zvidiki uye nzvimbo yakakura chaiyo. Saizi yezvikamu zvechisikigo zvemabhero anoyangarara inotangira pa1 kusvika 250 microns. Nzvimbo chaiyo yekumusoro i300-360cm2/g, iyo yakafanana nesimende. Nokudaro, mabhero anoyangarara haadi kukuyiwa uye anogona kushandiswa zvakananga. Kukora kwawo kunogona kusangana nezvinodiwa zvezvigadzirwa zvakasiyana-siyana. Zvimwe zvinhu zvekudzivirira kupisa zvishoma zvinowanzova zvezvikamu zvikuru (sePerlite). Kana zvikakuyiwa, kugona kwacho kuchawedzerwa zvakanyanya uye kudziya kwekupisa kuchaderedzwa zvakanyanya. Panyaya iyi, mabhero anoyangarara ane zvakanakira. Kudzivirira kwemagetsi kwakanaka. Bero rinoyangarara mushure mekusarudza bero remagineti ichinhu chakanaka chekudzivirira kupisa chisingafambise magetsi. Kudzivirira kwezvinodzivirira kupisa kunoderera nekupisa kuri kuwedzera, nepo kuramba kwemabharo anoyangarara kuchikwira nekupisa kuri kuwedzera. Izvi hazvina zvimwe zvinhu zvekudzivirira. Saka, zvinogona kushandiswa kugadzira zvigadzirwa zvekudzivirira kupisa pasi pemamiriro ekupisa kwakanyanya.
