Kev siv dav dav ntawm cov graphene dawb - kub kub tiv thaiv txheej txheej
Apr 19, 2022
Raws li aviation, spaceflight, tsheb, thiab kev loj hlob sai ntawm kev lag luam xws li riam phom, rau kev siv cov khoom siv hlau ua tau zoo dua thiab siab dua, tsis yog tsuas yog yuav tsum tau siv nyob rau hauv qhov kub thiab txias ntau dua thiab hnyav corrosive ib puag ncig, tab sis kuj tseem muaj cov khoom siv hlau. kev co kuj, qaug zog kuj, kub poob siab kuj thiab scouring kuj, organic polymer cov ntaub ntawv tau nyuaj ua tau raws li qhov yuav tsum tau siv.
Hexagonal boron nitride muaj cov tshuaj ruaj khov zoo, nws tseem ruaj khov ntawm 1000 degree hauv huab cua, 1400 degree hauv lub tshuab nqus tsev thiab 2800 degree hauv inert gas, thiab nws tsis ntub los yog ua rau feem ntau cov hlau melts xws li hlau, stainless hlau, txhuas, hlau thiab tooj liab, thiab muaj kev ua haujlwm zoo lubrication. Hexagonal boron nitride txheej muaj zog adhesion nrog substrate, siab hardness, txhuam tsis kam thiab cuam tshuam tsis kam. Nrog rau txoj kev loj hlob ntawm non-ferrous smelting kev lag luam, kub resistant boron nitride txheej yog dav siv nyob rau hauv lub ntws trough, shunting phaj, casting rooj hauv ob sab phlu, lim lub thawv, hloov phaj, casting nozzle, slag skimmer, pouring ladle, hloov ladle thiab lwm yam khoom nto.
