Hauj lwm lawm
Hexagonal boron nitride yog ib qho dawb, siab purity hexagonal crystalline hmoov nrog tib txheej txheej raws li graphite thiab muab cov khoom zoo lubrication / demudding. Graphite yog reactive heev, reacts yooj yim nrog hlau / oxides thiab ua hluav taws xob, thaum boron nitride yog hluav taws xob insulating thiab chemically / thermal stability, thiab ruaj khov ntawm kub txog li 3000 ° C nyob rau hauv ib tug inert cua.
Hexagonal boron nitride siv los ua boron nitride tso tawm tus neeg sawv cev tuaj yeem tsim cov txheej txheem tiv thaiv ntawm cov pwm, uas tuaj yeem tsis tsuas yog tiv taus cov pwm thiab cov kua hlau, tab sis kuj tuaj yeem tiv thaiv pwm thiab cov kua hlau los ntawm kev sib cuag. Boron nitride tso tawm tus neeg sawv cev muaj lubricity zoo thiab tsis hnov mob nrog hlau thiab lwm yam tshuaj, yog li cov nyhuv tso tawm yog qhov zoo heev.
CHAW UA HAUJ LWM BN
Siab thermal stability
Nyob ruaj khov txog li 3000 ° C hauv qhov chaw tsis muaj zog.
Siab corrosion kuj
ruaj khov rau feem ntau cov kuab tshuaj organic thiab cov tshuaj corrosive thiab tsis tuaj yeem wetted los ntawm feem ntau cov hlau molten thiab iav.
Cov yam ntxwv hluav taws xob siab
Nws muaj cov hluav taws xob rwb thaiv tsev siab thiab qhov hluav taws xob tsis zoo ntawm qhov kub thiab txias kom txog thaum lub dielectric tsis tu ncua thiab dielectric poob hauv cheeb tsam high-frequency tsis hloov.
Lubricity thiab demoulding efficiency
Kev sib txhuam coefficient tsis hloov pauv hauv cov huab cua nitrogen txawm tias qhov kub thiab txias, thiab tuaj yeem siv rau hauv huab cua ntawm qhov kub txog li 950 ° C.
High thermal conductivity thiab kub dissipation
High thermal conductivity, siab kub dissipation tuaj yeem siv rau txhua hom radiators
