Rhodium, feem ntau hu ua "kub dub", yog hlau platinum pawg uas muaj cov peev txheej thiab kev tsim khoom tsawg tshaj plaws. Cov ntsiab lus ntawm rhodium hauv lub ntiaj teb lub plhaub tsuas yog ib billionth ntawm ib billionth. Raws li cov lus hais tias, "yam uas tsis tshua muaj yog qhov muaj nqis", hais txog tus nqi, tus nqi ntawm rhodium tsis qis dua li kub kiag li. Nws suav hais tias yog cov hlau muaj nqis tsawg tshaj plaws thiab muaj nqis tshaj plaws hauv ntiaj teb, thiab nws tus nqi kim dua kub 10 npaug. Ua li no, 100kg tsis yog qhov me me.

Yog li, hmoov rhodium muaj dab tsi ua nrog fiberglass?
Peb paub tias cov iav fiber yog cov khoom siv inorganic uas tsis yog hlau nrog kev ua tau zoo heev, uas yog siv dav hauv cov teb tseem ceeb xws li hluav taws xob, kev tsim kho, aerospace, thiab kev thauj mus los. Hauv nws cov txheej txheem tsim khoom, muaj ib qho txheej txheem tseem ceeb heev - kev kos duab hlau, uas cov khoom siv raw tau yaj rau hauv cov kua iav ntawm qhov kub siab hauv lub qhov cub, thiab tom qab ntawd sai sai dhau los ntawm lub bushing porous kom raug kos rau hauv cov iav fiber strands.
Feem ntau ntawm cov porous bushings siv rau hauv cov iav fiber kos duab yog ua los ntawm platinum-rhodium alloys. Platinum tuaj yeem tiv taus qhov kub siab, thiab rhodium hmoov yog siv los ua cov khoom ntxiv rau lub zog ntawm cov khoom. Tom qab tag nrho, qhov kub ntawm cov iav kua yog ntawm 1150 thiab 1450 ° C. Kev tiv thaiv corrosion thermal.

Nws tuaj yeem hais tias platinum-rhodium alloy bushings yog qhov tseem ceeb heev thiab feem ntau siv cov khoom siv hauv cov iav fiber factories.
