Muaj ntau yam kev siv ntawm cov graphene dawb - kub resistant lubricant
Apr 08, 2022
Hexagonal boron nitride nyob rau hauv qis thiab siab kub (900 degree C) txawm nyob rau hauv cov pa oxygen yog ib yam zoo heev lubricant, uas ua rau nws nyob rau hauv lub conductivity ntawm graphite thiab reacts nrog rau lwm yam tshuaj uas tshwm sim tshwj xeeb tshaj yog siv tau txwv, thiab lubrication mechanism ntawm h. - BN tsis cuam tshuam rau theem ntawm cov dej molecules, boron nitride lubricant kuj siv tau rau hauv lub tshuab nqus tsev.
Los ntawm dispersing H-BN nyob rau hauv tshav kub resistant lubricating roj, dej los yog hnyav thiab sau nws nyob rau saum npoo ntawm resin, ceramic thiab hlau, kub resistant self-lubricating composite khoom siv tau nyob rau hauv aerospace engineering. H-bn ncua kev kawm ntawv yog dawb los yog lub teeb daj, nws yuav tsis pollute fiber ntau nyob rau hauv textile machinery, yog li nws yuav siv tau nyob rau hauv ib tug loj tus naj npawb ntawm hluavtaws fiber ntau textile machinery lubrication; Tsis tas li ntawd, H-BN lubricating roj kuj tseem siv tau rau cov roj lubricants kub, ultra-siab kub lubricants thiab cua sov resistant compressor roj thiab kub kub roj ntawm aircraft thiab spacecraft.
