Rhodium, yomwe imadziwika kuti "golide wakuda", ndi chitsulo cha gulu la platinamu chomwe chili ndi zinthu zochepa komanso kupanga. Kuchuluka kwa rhodium mu nthaka ya dziko lapansi ndi gawo limodzi mwa magawo biliyoni a biliyoni. Monga mwambi umanenera, "chosowa ndi chamtengo wapatali", ponena za mtengo wake, mtengo wa rhodium si wotsika kuposa wa golide konse. Imaonedwa kuti ndi chitsulo chamtengo wapatali chosowa kwambiri komanso chamtengo wapatali kwambiri padziko lonse lapansi, ndipo mtengo wake ndi wokwera mtengo ka 10 kuposa golide. Mwanjira imeneyi, 100kg si ndalama zochepa.

Rhodium yachitsulo chamtengo wapatali

Ndiye, kodi ufa wa rhodium umakhudzana bwanji ndi fiberglass?

Tikudziwa kuti ulusi wagalasi ndi chinthu chosapangidwa ndi chitsulo chomwe chimagwira ntchito bwino kwambiri, chomwe chimagwiritsidwa ntchito kwambiri m'magawo ofunikira monga zamagetsi, zomangamanga, ndege, ndi mayendedwe. Pakupanga kwake, pali njira yofunika kwambiri - kujambula waya, momwe zinthu zopangira zimasungunuka kukhala yankho lagalasi kutentha kwambiri mu uvuni, kenako zimadutsa mwachangu mu bushing yoboola kuti zikokedwe mu ulusi wagalasi.

Ma bushing ambiri okhala ndi machubu omwe amagwiritsidwa ntchito popanga ulusi wagalasi amapangidwa ndi platinum-rhodium alloys. Platinum imatha kupirira kutentha kwambiri, ndipo ufa wa rhodium umagwiritsidwa ntchito ngati chowonjezera cha mphamvu ya zinthu. Kupatula apo, kutentha kwa galasi lamadzimadzi kuli pakati pa 1150 ndi 1450 °C. Kukana dzimbiri pa kutentha.

Njira yojambulira yankho la galasi kudzera mu mbale yotulutsira madzi

Tinganene kuti ma bushings a platinum-rhodium alloy ndi njira yofunika kwambiri komanso yogwiritsidwa ntchito kwambiri popanga zinthu m'mafakitale agalasi.
