Rhenium Qws thiab Bar Description
Ntshiab rhenium pas nrig thiab bar (99.99 feem pua ntshiab) muab siab ductility thiab lub zog, tsim rau ntau yam kev siv xws li satellite positioning nozzles, aerospace propulsion Cheebtsam thiab lwm yam xav tau qhov chaw uas yuav tsum tau tiv heev thermal shock, siab kub thiab kev ntxhov siab daim ntawv thov.
SSC yog tus kws tshaj lij hauv kev tsim rhenium pas nrig thiab bar. Peb tsim rhenium pas nrig thiab rhenium bar los ntawm raw khoom APR (ammonium perrhenate) pib hmoov mus txog rau cov khoom tiav. Rhenium bar thiab rhenium pas nrig tuaj yeem dov mus rau cov neeg siv khoom tshwj xeeb. Peb kuj tuaj yeem tsim cov rhenium hlau los ntawm 0.025mm txog 3.175mm ntim rau hauv coils lossis ntawm spools.
