Qhov txawv ntawm Hexagonal Boron Nitride thiab Graphite
Aug 04, 2023
Hexagonal boron nitride zoo ib yam li graphite, cov qauv zoo sib xws, muaj qhov zoo sib xws, qhov kub thiab txias tsis kam, thiab cov menyuam skating, qhov txawv ntawm ob yam khoom no yog dab tsi?
Graphite yog tsim los ntawm tib lub ntsiab lus xws li cov pa roj carbon, tab sis txheej txheem sib txawv. Lub opaque grey-dub khoom nrog ib tug ceev ntawm 2.25, zoo heev corrosion kuj, thiab ib tug melting point txog li 3,600 degrees Celsius. Cov khoom siv tshuaj ruaj khov, thiab cov kua qaub thiab alkali tsis yooj yim rau kev hnov mob. Cov pa hluav taws kub hnyiab los ua cov pa roj carbon dioxide tab sis tuaj yeem oxidized los ntawm cov oxidants muaj zog, poov tshuaj permanganate, concentrated nitric acid, thiab lwm yam. Nws muaj nuj nqi yog siv los ua tus neeg sawv cev tiv thaiv, tuaj yeem siv los ua cov roj nplua nyeem, feem ntau siv los ua cov khoom siv hluav taws xob thiab mem hluav lead thiab lwm yam.
Hexagonal boron nitride tseem hu ua dawb pob zeb ink, dawb hmoov zoo li, vim hais tias cov nitrogen thiab boron nyob rau hauv hexagonal boron nitride kuj tsim hexagonal mesh txheej, sib tshooj sib sib zog nqus, tsim muaju, muaju thiab graphite zoo sib xws, tsis zoo ib yam. Hexagonal boron nitride muaj cov thermal conductivity zoo, tiv taus kub kub, rwb thaiv tsev, thiab lubrication, feem ntau siv los ua cov roj nplua nyeem kub, kuj tuaj yeem siv ua PA, PE, thiab lwm yam khoom siv polymers; Additives ntawm ntau yam thermal interface cov ntaub ntawv, txhim khu thermal conductivity, li cosmetic additives, mos thiab muaj pearlescent nyhuv.
Peb tuaj yeem ua cov duab sib txawv ntawm ceramics raws li koj xav tau thiab koj daim duab, txais tos thiab tos ntsoov rau koj qhov kev nug!
