ZINDIKIRANI: Zizindikiro zaukadaulo zomwe zili pamwambapa zimangoyimira mfundo wamba zomwe zimagwiritsidwa ntchito pofotokozera.
Kupaka zinthu: 1 kg/thumba, kuyika thumba la zojambulazo za aluminiyamu, 10 kg/katoni (malinga ndi pempho la makasitomala kuti alembe chizindikiro)
Boron nitride Ndi kristalo wopangidwa ndi maatomu a nayitrogeni ndi maatomu a boron. Kapangidwe ka kristalo kamagawidwa m'magulu awa: hexagonal boron nitride (HBN), hexagonal boron nitride (WBN) ndi cubic boron nitride. Pakati pawo, kristalo wa hexagonal boron nitride Kapangidwe kake kali ndi kapangidwe kofanana ndi graphite, kowonetsa kutayirira, mafuta, kuyamwa chinyezi, komanso ufa woyera wopepuka, kotero kamatchedwanso "graphite yoyera". Kuchuluka kwa chiphunzitso ndi 2.27g/cm3, mphamvu yokoka ndi 2.43, ndipo kuuma kwa Mohs ndi 2.
Hexagonal boron nitride Ili ndi kutchinjiriza kwabwino kwamagetsi, kutentha kumayendetsedwa bwino. Kukhazikika kwa mankhwala, palibe malo osungunuka oonekera bwino, 3000°C mu 0.1MPA nayitrogeni, mumlengalenga wochepetsera kutentha, kukana kutentha kufika pa 2000°C, yomwe imagwiritsidwa ntchito mu nayitrogeni ndi argon kutentha kumatha kufika pa 2800°C, kukhazikika kwake ndi kofooka mumlengalenga wa okosijeni, ndipo kutentha komwe kumagwiritsidwa ntchito kuli pansi pa 1000°C. Kuchuluka kwa hexagonal boron nitride ndi kofanana ndi kwa quartz, koma kutentha kumayendetsedwa bwino nthawi khumi kuposa kwa quartz. Ilinso ndi mafuta abwino kwambiri pa kutentha kwambiri. Ndi mafuta abwino kwambiri otentha kwambiri okhala ndi mphamvu yoyamwa neutron, mankhwala okhazikika, komanso osagwira ntchito ndi mankhwala pafupifupi zitsulo zonse zosungunuka.
Hexagonal boron nitride Sisungunuka m'madzi ozizira. Madzi akaphikidwa, amasungunuka pang'onopang'ono kwambiri ndipo amapanga boric acid ndi ammonia pang'ono. Sachitapo kanthu ndi ma acid ofooka ndi maziko olimba kutentha kwa chipinda. Amasungunuka pang'ono mu asidi yotentha. Gwiritsani ntchito sodium hydroxide yosungunuka ndi potaziyamu hydroxide. Kukonza kumatha kuwola. Ali ndi kukana dzimbiri kwa ma inorganic acid osiyanasiyana, alkalis, mchere ndi zosungunulira zachilengedwe.
Magawo osiyanasiyana ogwiritsira ntchito ndi awa:
| Chothandizira kutulutsa nkhungu popanga zitsulo ndi mafuta odzola waya | Zapadera pansi pa electrolysis yotentha kwambiri, zipangizo zotsutsa | Ingagwiritsidwe ntchito pa kutentha kwambiri, kuthamanga kwambiri, kutchinjiriza ndi kutentha kwambiri | Zowonjezera zotsutsana ndi kuvala mafuta otentha kwambiri |
|
Desiccant yotseka kutentha ya transistor yowonjezera zina za polima |
Chitetezo cha kutentha mumlengalenga Zinthu Zofunika |
Pambuyo pa kutentha kwambiri komanso kupanikizika kwambiri, imatha kusinthidwa kukhala cubic boron nitride yolimba ngati diamondi. |
Kapangidwe ka zida za atomiki f |

Yoyenera kugwiritsa ntchito nozzle ya injini ya roketi ya ndege |
Chotenthetsera chamagetsi champhamvu komanso cha pafupipafupi kwambiri ndi zina zotero. chotenthetsera cha ion arc |
Zitsulo zogwiritsidwa ntchito popanga mphete yolekanitsa zitsulo zopitilira |
Mitundu yonse ya ma aluminiyamu opangidwa ndi capacitor film |
|
Mitundu yonse ya matumba ophikira aluminiyamu atsopano ndi zina zotero… |
Zinthu zosiyanasiyana zopopera aluminiyamu zopangidwa ndi laser zotsutsana ndi zinthu zabodza |
Amagwiritsidwa ntchito mu zodzaza zokongoletsa |
Zowonjezera zowonjezera kutentha zomwe sizimatenthedwa ndi kutentha kwambiri |
★Malangizo achitetezo: Chogulitsachi ndi chapamwamba kwambiri, sichidyedwa, muyenera kuvala masks achitetezo ndi magolovesi a rabara mukachigwiritsa ntchito.
Nkhani yokhudza kusunga ndi mayendedwe:
1. Katunduyu sangayaka moto ndipo sangaphulike ndipo akhoza kusungidwa ndikunyamulidwa ngati mankhwala wamba.
2. Sungani pamalo ozizira komanso ouma, pewani mvula, chinyezi, ndipo pewani kudya molakwika
