Yakakosha Metal Re yekupisa tembiricha alloy
Tsanangudzo
Rhenium (Re) isimbi isingawanzo uye yakakosha refractory ine zvimiro zvakasarudzika zvinoita kuti idiwe zvakanyanya kune akasiyana maapplication.Isirivha-chena, simbi inorema ine nzvimbo yakanyanyisa kunyunguduka uye yakakwira density, zvichiita kuti ive chinhu chakakodzera kushandiswa mukupisa kwepamusoro uye kushushikana kwakanyanya.
Imwe yemashandisirwo ekutanga erhenium mukugadzirwa kweyepamusoro-tembiricha alloys yekushandiswa mumajini ejeti.Kutaura zvazviri, inenge 70% yerhenium yenyika inoshandiswa nenzira iyi.Rhenium inowedzerwa kune aya alloys kuti avandudze mashandiro avo epamusoro-tembiricha, kusanganisira simba rawo, kusimba, uye kuramba kupfeka uye ngura.
Chimwe chakakosha kushandiswa kwerhenium mukugadzirwa kweplatinum-rhenium catalysts.Macatalyst aya anoshandiswa muindasitiri yemakemikari kukurudzira kushandurwa kwemahydrocarbon nemamwe macommunication kuita zvigadzirwa zvinobatsira, zvakaita sepeturu, mapurasitiki, nemamwe makemikari.
Pamusoro pezvishandiso izvi, rhenium yakashandiswawo mune mamwe minda, senge muindasitiri yezvemuchadenga yemaroketi nozzles uye muindasitiri yemagetsi yekubatanidza magetsi nezvimwe zvinhu.Nekuda kwekushomeka kwayo uye kudhura kwayo, rhenium inoonekwa sesimbi yakakosha uye inokosheswa nekuda kwezvimiro zvayo zvakasiyana uye huwandu hwakawanda hwekushandisa.
