I-Rhodium, eyaziwa ngokuba yi-"black gold", yintsimbi yeplatinum enezixhobo ezincinci kunye nemveliso. Umxholo we-rhodium kuqweqwe lomhlaba yibhiliyoni enye kuphela yebhiliyoni. Njengoko intetho isitsho, "okunqabileyo kuxabisekile", ngokwexabiso, ixabiso le-rhodium alikho ngaphantsi kunelegolide konke konke. Ithathwa njengesinyithi esinqabileyo nesixabisekileyo kakhulu emhlabeni, kwaye ixabiso layo libiza ngokuphindwe kalishumi kunegolide. Ngale ndlela, i-100kg ayisiyonto incinci.

I-rhodium yesinyithi exabisekileyo

Ngoko ke, i-rhodium powder inantoni na ne-fiberglass?

Siyazi ukuba i-glass fiber yinto engeyiyo i-metallic engaphiliyo enentsebenzo egqwesileyo, esetyenziswa kakhulu kwiindawo eziphambili ezifana ne-elektroniki, ulwakhiwo, i-aerospace, kunye nothutho. Kwinkqubo yayo yokuvelisa, kukho inkqubo ebaluleke kakhulu - umzobo wentambo, apho izinto ezikrwada zinyibilikiswa zibe yisisombululo seglasi kubushushu obuphezulu kwi-oven, kwaye emva koko zidlule ngokukhawuleza kwi-bushing enemingxuma ukuze zitsalwe kwimicu ye-glass fiber.

Uninzi lwee-bushings ezinemibhobho ezisetyenziswa ekudwebeni ifayibha yeglasi zenziwe ngee-alloys zeplatinum-rhodium. I-Platinum inokumelana namaqondo obushushu aphezulu, kwaye i-rhodium powder isetyenziswa njengesongezelelo sokuqina kwezinto. Kaloku, amaqondo obushushu eglasi engamanzi aphakathi kwe-1150 kunye ne-1450 °C. Ukumelana nokugqwala kobushushu.

Inkqubo yokuzoba isisombululo seglasi ngepleyiti yokuvuza

Kunokuthiwa ii-bushings ze-platinum-rhodium alloy zibaluleke kakhulu kwaye zisetyenziswa kakhulu ekuveliseni kwiifektri zefayibha yeglasi.
