Floating bead imhando yefly ash hollow ball inokwanisa kuyangarara pamusoro pemvura.Iyo grey chena, nhete uye ine mhango mumadziro, yakareruka muhuremu, iine huremu hwe720kg/m3 (inorema) uye 418.8kg/m3 (chiedza), saizi yechidimbu ingangoita 0.1mm, yakavharwa uye yakatsetseka pamusoro, idiki mukati. Thermal conductivity, uye moto kuramba ≥ 1610 ℃.Iyo yakanakisa tembiricha inochengetedza refractory, inoshandiswa zvakanyanya mukugadzirwa kwemwenje castables uye kuchera mafuta.Kemikari yebhidhi inoyangarara inonyanya kuve silicon dioxide uye aluminium oxide.Iine hunhu hwakawanda, senge zvidimbu zvidimbu, buri, huremu huremu, simba rakanyanya, kupfeka kuramba, kupikisa kwekushisa kwepamusoro, kupisa kwemafuta, kusungirira uye kudzoreredza moto.Icho chimwe chezvinhu zvakasvibirira zvinoshandiswa zvakanyanya muindasitiri yekudzivirira moto.

Nhanganyaya

Kuita kwakanakisa uye kushandiswa kwemabhedhi anoyangarara

High moto resistance.Iyo mikuru yemakemikari inoumba bead inoyangarara isilicon nealuminium oxides, iyo silicon dioxide inenge 48-66% uye aluminium oxide inenge 26-36%.Nekuti panonyungudika silicon dioxide 1720 ℃ uye iyo yealuminium oxide i2060 ℃, ese ari maviri akakwira refractories.Naizvozvo, bead inoyangarara ine yakanyanya kupikisa moto, iyo inowanzosvika 1620-1800 ℃, ichiiita yakanakisa-inoshanda refractory.Uremu huremu, kupisa kwemafuta.Rusvingo rwebead inoyangarara itete uye mhango, uye mhango isemi vacuum.Pane gasi shoma chete (N2, H2, CO2, nezvimwewo), uye kupisa kwemhepo kunononoka zvakanyanya.Nokudaro, mabheji anoyangarara haasi kungoita chiedza chete muhuremu (250-450 kg/m3).Hukuru hwechimedu hwemabhero anoyangarara ndeye 1-250 microns.Drift beads inogona kushandiswa zvakananga pasina kugaya.Iyo fineness inogona kusangana nezvinodiwa zvezvakasiyana zvigadzirwa.Zvimwe zviremekedzo zvemafuta ekudzivirira zvinyoro zvinowanzova zvehukuru hukuru (senge perlite).Kana vakakuyiwa, simba richawedzerwa zvikuru, uye kupisa kwekushisa kuchaderedzwa zvikuru.Panyaya iyi, Drifting beads ane zvakanakira.Yakanakisa magetsi ekudzivirira.Iyo bhedhi inoyangarara mushure mekunge magineti bead yasarudzwa ndeye insulating material ine basa repamusoro uye haifambisi magetsi.Kazhinji, kuramba kwezvidziviriri kunodzikira nekuwedzera kwekushisa, nepo uko kwemabhedhi anoyangarara kunowedzera nekuwedzera kwekushisa.Iyi bhenefiti haina kune zvimwe insulating zvinhu.Naizvozvo, inogona kushandiswa kugadzira insulating zvigadzirwa pasi pekupisa kwakanyanya.
