Hexagonal boron nitride Ufa wa (HBN) uli ndi mphamvu yabwino yoyendetsera kutentha, mphamvu zake za m'mphepete, kukhazikika kwa mankhwala komanso mphamvu yake yopangira mafuta. Kutentha kwake kotsutsana ndi okosijeni kumapitirira 2000°C, komanso mphamvu yake yopangira mafuta kutentha kwambiri. Umagwiritsidwa ntchito makamaka pokonzekera cubic boron nitride, zokutira zotentha kwambiri, zodzaza, ma hBN agglomerates, ndi zina zotero. Boron oxide
(1) Makampani opanga zinthu zolimba kwambiri. Amagwiritsidwa ntchito pokonzekera nitride ya cubic boron. Nitride ya cubic boron ndi hexagonal boron nitride yowonjezeredwa ndi chothandizira chochokera ku lithiamu kapena magnesium, chomwe chingasinthidwe kukhala cubic boron nitride pansi pa kutentha kwakukulu. Pakadali pano, makampani am'nyumba amagwiritsa ntchito matani opitilira 400 a hexagonal boron nitride chaka chilichonse.
(2) Makampani opanga utoto. Pambuyo poti hBN yapakidwa pa chitsulo, zoumba ndi zinthu zina, imatha kupangitsa kuti zinthuzo zikhale ndi mafuta abwino pamwamba komanso zoletsa kuuma (kutulutsa), ndipo imatha kuletsa kapena kuchepetsa kuyankhika kwa mankhwala pakati pa zinthuzo ndi kusungunuka, ndikupangitsa kuti zinthuzo zikhale ndi moyo; Zophimba zatsopano zosiyanasiyana zotenthetsera kutentha kwa ma radiator ndi zida zamagetsi kuti ziwonjezere kutentha. Ndi yoyenera ma radiator a mafakitale a photoelectric, ma module oziziritsa ziwalo zamagetsi, ma module oziziritsa mphamvu, ma radiator a magalimoto, ma oil cooler, ma gearbox oil cooler, ndi mitundu ina ya ma cooler.
(3) Makampani azinthu zamagetsi. Akagwiritsidwa ntchito ngati chodzaza zinthu zotenthetsera kutentha kwambiri, hBN imakhala ndi kukana kutentha kwambiri, kukana dzimbiri bwino, kukana kutentha pang'ono komanso kutentha kwambiri. Ndi chinthu choyenera kutentha m'mphepete ndipo chimatha kusintha kutentha kwa zinthu zamagetsi zochokera ku utomoni. Linganizani.
(4) Makampani opanga zodzoladzola apamwamba kwambiri. Akagwiritsidwa ntchito ngati chodzazira chapamwamba kwambiri, amatha kuwonjezera mphamvu yomatira ndi kubisala zodzoladzola, ndipo amakhala ndi mawonekedwe otsetsereka bwino, zomwe zimapangitsa zodzoladzola kukhala zazing'ono, zosavuta kugwiritsa ntchito, zosavuta kuyeretsa ndi kuchotsa, komanso ndizovulaza thupi la munthu. Pakadali pano, makampani opanga zodzoladzola apamwamba kwambiri amagwiritsa ntchito matani opitilira 200 a hexagonal boron nitride pachaka.
(5) Makampani opangira mafuta. Monga chowonjezera pa zinthu zolimba ndi zamadzimadzi zopangira mafuta. Kuwonjezera mafuta opangira mafuta kungathandize kuti mafuta azigwiritsidwa ntchito bwino, kupititsa patsogolo magwiridwe antchito a masilinda, komanso kukhala ndi zotsatira zabwino zopulumutsa mphamvu.
(6) Makampani opanga zinthu zadothi apamwamba, omwe amagwiritsidwa ntchito pokonzekera ma hBN agglomerates. Ma hBN agglomerates ali ndi kutentha kwambiri, kutentha kwambiri, mphamvu zamagetsi ndi dielectric zabwino kwambiri, ndipo nthawi zambiri amagwiritsidwa ntchito pokonzekera kutentha kwambiri komanso kupanikizika kwambiri, zida zamagetsi zotentha kwambiri, ma crucibles ndi ma molds, komanso mawindo otseguka kwambiri komanso okhazikika kwambiri. Missile radome, zenera la antenna la microwave ndi zida zina.
Timapereka mitundu yambiri komanso yapamwamba kwambiriHexagonal boron nitride, tsatanetsatane monga motere
