Dab tsi yog kev siv tshwj xeeb ntawm graphite carbon rods?
1. Daim ntawv thov nyob rau hauv kev lag luam atomic zog thiab kev lag luam tiv thaiv lub teb chaws: Graphite muaj ib tug zoo neutron txo tus neeg saib xyuas thiab siv nyob rau hauv atomic reactors. Uranium-graphite reactors tam sim no siv nyob rau hauv ntau lub atomic reactors. Raws li cov khoom deceleration ntawm lub hwj chim reactor, nws yuav tsum muaj cov yam ntxwv ntawm siab melting point, stability thiab corrosion kuj. Graphite tuaj yeem ua tau raws li qhov xav tau saum toj no. Graphite siv nyob rau hauv atomic reactors yuav tsum tau purity siab heev, thiab impurities yuav tsum tsis txhob ntau tshaj li ob peb kaum ntawm ib lab. Tshwj xeeb, cov ntsiab lus boron yuav tsum tsawg dua 0.5ppm. Graphite kuj tseem siv rau hauv kev lag luam tiv thaiv los ua cov nozzles rau cov roj foob pob hluav taws, lub qhov ntswg cones rau cov cuaj luaj, qhov chaw rau cov khoom siv hauv chaw navigation, rwb thaiv tsev kub thiab hluav taws xob tiv thaiv.
2. Raws li cov khoom siv refractory: Graphite thiab nws cov khoom muaj cov yam ntxwv ntawm qhov kub thiab txias tsis kam thiab siab zog. Lawv tsuas yog siv hauv kev lag luam metallurgical los tsim cov graphite crucibles.
3. Cov khoom siv hluav taws xob: siv hauv kev lag luam hluav taws xob los ua cov electrodes, carbon rods, carbon tubes, txhuam, mercury rectifier zoo electrodes, graphite washers, xov tooj accessories, TV duab raj coatings, thiab lwm yam. Raws li ib tug hnav-resistant lubricating khoom, graphite yog feem ntau siv los ua cov roj nplua nyeem hauv kev lag luam machinery. Lubricating roj feem ntau tsis tuaj yeem siv nyob rau hauv high-speed, high-temperature, thiab high-pressure tej yam kev mob, tab sis graphite hnav-resistant cov ntaub ntawv tuaj yeem xaub ntawm qhov kub ceev ntawm qhov kub ntawm 200 txog 2000 degree yam tsis tas siv cov roj lubricating. Ntau yam khoom siv thauj khoom corrosive yog ua los ntawm cov khoom siv graphite, xws li piston khob, sealing rings thiab bearings. Graphite emulsion kuj yog cov roj nplua nyeem zoo rau ntau cov hlau ua haujlwm (xov hlau, kos duab raj).
