Kev siv Boron nitride hauv tshuaj pleev ib ce
Dec 02, 2021
boron nitride yog dab tsi?
Boron nitride yog siv lead ua uas muaj nitrogen thiab boron atoms, cov tshuaj formula yog BN, nws muaj ntau hom siv lead ua, thiab txhua lub siv lead ua muaj nws cov khoom zoo heev. Raws li cov khoom siv tshiab, boron nitride tau siv ntau dua thiab siv ntau yam tshiab thiab cov khoom tshiab. Nws daim ntawv thov tau txhim kho cov txheej txheem kev lag luam niaj hnub no thiab txhawb txoj kev loj hlob ntawm cov khoom siv tshiab kev lag luam mus rau qhov tob thiab dav.
Hexagonal boron nitride yog dab tsi?
Hexagonal boron nitride (hBN), hu ua" dawb graphite" vim nws cov qauv crystalline zoo ib yam li graphite, yog cov roj nplua nyeem nrog kev ua tau zoo heev. Nws feem ntau yog hmoov dawb.
Hexagonal boron nitride yog ib tug zoo conductor ntawm tshav kub thiab ib tug insulator ntawm hluav taws xob, muaj tshuaj lom neeg stability, tsis muaj kev sib txhuam coefficient, thiab zoo lubrication kev ua tau zoo, tshwj xeeb tshaj yog nyob rau hauv high kub, nws tseem muaj zoo heev tus kheej lubrication muaj peev xwm.
Qhov zoo ntawm hexagonal boron nitride hauv tshuaj pleev ib ce
Hauv kev tshuaj pleev ib ce, qhov ua tau zoo thiab permeability ntawm cov tshuaj nquag rau hauv daim tawv nqaij yog ncaj qha ntsig txog qhov loj me, thiab qhov loj me ntawm cov tshuaj pleev ib ce yog qhov tseem ceeb vim tias cov kab me me tuaj yeem ua rau thaj tsam ntawm qhov chaw thiab muaj peev xwm encapsulate cosmetic active tshuaj.
Hexagonal boron nitride (H-BN) nanomaterials tuaj yeem tswj qhov loj ntawm cov khoom sib txuas. Hexagonal boron nitride muaj cov txiaj ntsig zoo hauv cov tshuaj pleev ib ce, tshwj xeeb tshaj yog cov khoom siv tshuaj pleev thaiv hnub. Nws tso cai rau kev tswj hwm ntawm nanostructures ntawm ntau theem ntawm kev tsim, yog li tswj qhov loj thiab qhov chaw. Thiab nws muaj kev ua tau zoo hauv dispersion, yog non-toxic, pob tshab, thiab chemically inert.
