Lubricating Properties Ntawm Boron Nitride
Apr 07, 2024
Boron nitride (BN) yog cov khoom siv uas paub txog nws cov khoom zoo heev. Nws muaj superior lubrication rau ntau lwm yam ntaub ntawv vim nws cov qauv thiab cov yam ntxwv. BN yog cov roj nplua nyeem uas muaj cov txheej txheem txheej zoo ib yam li graphite. Txawm li cas los xij, tsis zoo li graphite, BN yog cov khoom siv tawv heev thiab hnav-tiv taus uas tuaj yeem tiv taus ntau yam kub, siab, thiab ib puag ncig.
Ib qho txiaj ntsig tseem ceeb ntawm kev siv BN ua cov roj nplua nyeem yog nws lub peev xwm los txo kev sib txhuam thiab hnav. BN tsim cov txheej txheej nyias nyias, muaj zog, thiab ruaj khov ntawm cov hlau, uas txo qhov kev sib txhuam ntawm qhov chaw thiab txo qhov hnav thiab tsim kua muag. Qhov no ua rau nws zoo heev lubricant rau machinery qhov chaw uas yuav raug kev nyuaj siab thiab kev sib cuag pressures.
Tsis tas li ntawd, BN muaj cov khoom siv thermal zoo, uas ua rau nws muaj cov roj nplua nyeem tsim nyog rau cov ntawv thov kub xws li hauv cov cav tsheb thiab cov tshuab ua haujlwm. Nws cov thermal stability pab tswj cov khoom lubrication nyob rau hauv ntau qhov kub thiab txias, tsis muaj kev tawg lossis poob nws lub peev xwm lubrication.
Lwm qhov txiaj ntsig tseem ceeb ntawm BN ua lub roj nplua nyeem yog nws cov tshuaj lom neeg ruaj khov. BN yog inert rau feem ntau cov tshuaj, kuab tshuaj, thiab acids, uas ua rau nws ib tug txhim khu kev qha thiab ntev lub sij hawm lubricant uas yuav siv tau nyob rau hauv hnyav ib puag ncig.
Hauv kev xaus, kev siv BN ua cov roj nplua nyeem muaj ntau yam txiaj ntsig ntawm kev txo qis kev sib txhuam thiab hnav, tswj thermal stability, thiab tshuaj tiv thaiv. Nws cov khoom tshwj xeeb ua rau nws cov roj nplua nyeem zoo dua piv rau lwm cov ntaub ntawv, thiab nws tau dhau los ua kev xaiv nrov rau ntau daim ntawv thov kev lag luam, xws li aerospace thiab tsheb mus rau cov tshuab hnyav.
Shengyang New Material Co., Ltd. tau cog lus rau kev tsim cov boron nitride thiab boron nitride ua cov khoom, thiab tuaj yeem kho ntau yam boron nitride insulating ceramic qhov chaw raws li cov neeg siv khoom xav tau. Tiv tauj peb yog tias tsim nyog.
