Rhodium, yomwe imadziwika kuti "golide wakuda", ndiye gulu la platinamu chitsulo chokhala ndi zinthu zochepa komanso kupanga.Zomwe zili mu rhodium m'nthaka ya dziko lapansi ndi gawo limodzi mwa magawo mabiliyoni a biliyoni imodzi.Monga mawu akuti, "chosowa ndi chamtengo wapatali", ponena za mtengo, mtengo wa rhodium siwotsika kuposa wa golidi konse.Imaonedwa kuti ndi chitsulo chamtengo wapatali komanso chosowa kwambiri padziko lonse lapansi, ndipo mtengo wake ndi wokwera mtengo ka 10 kuposa golide.Mwa njira iyi, 100kg si ndalama zochepa.

Mtengo wachitsulo rhodium

Ndiye, ufa wa rhodium umagwirizana bwanji ndi fiberglass?

Tikudziwa kuti galasi CHIKWANGWANI ndi inorganic sanali zitsulo chuma ndi ntchito kwambiri, amene chimagwiritsidwa ntchito m'magawo ofunika monga zamagetsi, zomangamanga, Azamlengalenga, ndi mayendedwe.Pakupanga kwake, pali njira yofunikira kwambiri - kujambula kwa waya, momwe zopangira zimasungunuka mu galasi lagalasi pa kutentha kwakukulu mu ng'anjo, ndiyeno mwamsanga zimadutsa porous bushing kuti zikokedwe muzitsulo zamagalasi.

Zambiri mwazitsulo zomwe zimagwiritsidwa ntchito pojambula ulusi wagalasi zimapangidwa ndi platinamu-rhodium alloys.Platinamu imatha kupirira kutentha kwambiri, ndipo ufa wa rhodium umagwiritsidwa ntchito ngati chowonjezera champhamvu zakuthupi.Kupatula apo, kutentha kwa galasi lamadzimadzi kuli pakati pa 1150 ndi 1450 ° C.Thermal dzimbiri kukana.

Kujambula njira yothetsera galasi kupyolera mu mbale yotayira

Titha kunena kuti platinamu-rhodium alloy bushings ndi yofunika kwambiri komanso njira zomwe zimagwiritsidwa ntchito popanga m'mafakitale opangira magalasi.
