Tham txog daim ntawv thov ntawmhexagonal nano boron nitridenyob rau hauv cov tshuaj pleev ib ce

1. Qhov zoo ntawm hexagonal boron nitride nanoparticles hauv kev ua kom zoo nkauj

Hauv kev ua kom zoo nkauj, qhov ua tau zoo thiab permeability ntawm cov khoom siv rau hauv daim tawv nqaij yog ncaj qha ntsig txog qhov loj me, thiab qhov loj me 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 tuaj yeem ua rau lub ntsej muag kom zoo nkauj.Lub hexagonal boron nitride (h-BN) nanomaterial tuaj yeem tswj qhov loj ntawm cov khoom sib xyaw.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, uas tso cai rau cov nanostructures los tswj ntawm ntau theem ntawm kev tsim los tswj qhov loj thiab qhov chaw;thiab nws muaj cov khoom zoo heev hauv dispersion, non-toxic, transparency thiab chemically inert.

2. Infrared radiation sunscreen kev tshawb fawb ntawm Nano Boron Nitride

Nws paub zoo tias hnub ci hluav taws xob tuaj yeem ua rau kev noj qab haus huv ntawm daim tawv nqaij.Qhov ntau ntawm lub hnub ci zog feem ntau mus txog saum npoo ntawm lub ntiaj teb yog ultraviolet thiab infrared.Cov teebmeem ntawm UV teeb ua rau muaj kev phom sij rau cov tawv nqaij noj qab haus huv thiab tuaj yeem ua rau muaj mob qog noj ntshav, kev laus thiab lwm yam kev hloov ntawm daim tawv nqaij tsis zoo, thiab ua rau lub hnub kub hnyiab, erythema thiab o.Infrared rays ua rau kom muaj kev puas tsuaj thiab ua ntej kev laus ntawm ultraviolet rays rau ntawm daim tawv nqaij, thiab infrared hluav taws xob kuj yuav muaj peev xwm rau photocarcinogenesis.

Kev lag luam tshuaj pleev ib ce kev tshawb fawb ntawm cov khoom siv tshuaj pleev thaiv hnub tau nyob rau lub sijhawm ntev.Cov tshuaj pleev thaiv hnub tau tsim los siv nanoscience thiab kev paub txog nanotechnology, xws li nano titanium dioxide, cov khoom siv tshuaj pleev ib ce tseem ceeb rau tshuaj pleev thaiv hnub UV rays.Txawm li cas los xij, rau kev tiv thaiv hluav taws xob tiv thaiv hluav taws xob, muaj ntau qhov kev tshawb fawb tshuaj pleev thaiv hnub, thiab hauv qhov no, nws yog ib qho tsim nyog yuav tsum tau ua cov tshuaj pleev thaiv hnub uas muab UV thiab IR tiv thaiv.Boron nitride nanopowders yog cov ntaub ntawv muaj peev xwm vim tias lawv tswj qhov loj ntawm cov khoom sib xyaw, uas yog ib qho tseem ceeb hauv kev siv tshuaj pleev thaiv hnub.Nws kuj txo cov luster ntawm cov tawv nqaij oily vim nws cov thermal conductivity siab.Titanium dioxide nanoparticles uas muaj nanostructured boron nitride yog ib qho kev sib xyaw zoo tshaj plaws uas tuaj yeem siv los ua cov tshuaj pleev ib ce los tiv thaiv lub cev los ntawm hluav taws xob infrared ntawm lub hnub.

Tau kawg, daim ntawv thov ntawm hexagonal boron nitride nanoparticles nyob rau hauv cov tshuaj pleev ib ce tsis yog tsuas yog tshuaj pleev thaiv hnub.Qhov ntau yam ntawm cov tshuaj pleev ib ce yog nplua nuj heev.Ntxiv nrog rau cov tshuaj pleev ib ce, daim ntawv thov ntawm lwm thaj chaw ntawm hexagonal boron nitride nanoparticles kuj yog qhov dav heev, thiab tuaj yeem siv rau kev tsim khoom siv ceramics, xws li crucible, aluminium evaporation nkoj, Circuit Court board substrates thiab kub lubricants, kuj yog siv los ua cov khoom siv. rau nuclear reactors thiab foob pob ua ntxaij cav units.
