(SNBN Kuphwanya mpheteOpangidwa ndiWntrustek)

Kupsinjika kosalekeza kumafunikira kusunthira zinthu zosungunula kuchokera komwe kumapangitsa kuti zikhale zopachika kwa graphite kumwalira ndi zozizira pamsonkhano osagwiritsa ntchito mphamvu yokoka. Pambuyo popita kwa graphite amafa komanso zingapo zogwirizira, zinthu zosungunula zimadutsa mphete yoyambirira yotchedwa mphete yodutsa kuti ilowetse malo okhazikika. Ndikofunikira kuti mphete yosweka ikakhalabe ndi mtima wosagawanika mwadzidzidzi zomwe zimachitika pomwe malo otentha amapereka kumalo ozizira (malo okhazikika). Iyenera kulola zinthu zosungunula kuti ziziyenda momasuka popanda kumamatira kapena kumanga pamsewu. Ringle Rings ndi gawo lofunikira kwambiri poponyera mosalekeza, ngakhale akuwoneka kuti ali gawo lowongoka la msonkhano wathunthu. Kutentha konse kumatayika mu mwambowu kuti magawowa alephera kapena kuthyoka, potuluka chiwopsezo cha chitetezo chambiri ndikuyika nthawi yayitali kuti alowe m'malo ndikuyeretsa.

Boron nitrideimawonetsa kutentha kwakukulu, kukana kwa kutentha kwambiri, kutsuka kwamagetsi, ndi mawonekedwe owonda. Pa 1800 ° C, imakhala ndi bala lokhazikika ndikukhazikika motsutsana ndi kaboni ndi kaboni monoxide. Kuphatikiza apo, chitsulo chosungunula, mchere wosungunula, komanso osakhala ozizira sakung'amba. Kuphatikiza apo, bn atha kupangidwa mu zidutswa zowoneka bwino kwambiri ndipo ndizofunikira. Kupukutira kosalekeza kwa mpweya wolekanitsidwa kwa chitsulo chosungunula chapangitsa kuti a Boron Nitring Shings. Mumlengalenga ndi vacuum yayitali, imatha kupitiliza kupaka mafuta pomwe pali kutentha kwambiri.

Boron nitrideUfulu Wabwino

• Kunyowa kochepa chitsulo

• Kuchuluka kwa mafuta otsika komanso mawonekedwe amphamvu kwambiri

• Kuyerekezera kofanana kwambiri ndi kutentha

• Kutentha kwambiri kwambiri ndi kutetezedwa koyenera motsutsana ndi magesi

Bn ceramicAli ndi mitundu yambiri yopanga,StbnAmachita bwino kwambiri mu zida zopitilira zopumira:

Zikafika poyenda mosalekeza kwa zitsulo zosasangalatsa,SNBN (Boron nitride + silicon nitride)Citemite imachita bwino kwambiri. Mphetezo ndizabwino kutsimikizira kudzipatula komanso momveka bwino panthawi yopanda zitsulo popeza sikumanyowa kwa chitsulo chosungunula, oxidation - komanso mankhwala.

Zabwino zaSNBN Kuphwanya mphete

• Oxidation kugonjetsedwa: mpaka 1000 ° C mlengalenga

• Wokhazikika-temple streb: Mu vacuum kapena mpweya, mpaka 1700-1800 ° C

• Zosanyowa: zimalepheretsa slag ndi zitsulo kuti zisinthe

• Kukokoloka ndi zokongoletsa: Kuthana ndi zitsulo zonyamula ndipo sagwirizana

Ubwino waSNBN Kuphwanya mphetePoyerekeza ndi mphete ya graphite

SNBN CORATIM IFETING Rings, omwe amapangidwira njira zopsinjika zolimba, uzichita bwino kuposa mphete zojambula chifukwa ndi mfulu kuipitsidwa ndi kaboni komanso kukhala ndi mankhwala ochulukirapo a kaboni. Malo awo osanyowa ndi mawonekedwe awo pansi pa kutentha kutentha kumatsimikizira kumaliza malizani omaliza komanso kuyenda kosalala.

Zolemba wamba

• Njira zopitilira zopingasa zokhala ndi zitsulo zosasangalatsa

• Zotchinga za cyramic zamkuwa, nickel, ndi aluminiyamu oyang'anira

• Kuyimitsa kwa Graphite ku Contration

• Zophatikiza zosagwirizana ndi oxidation
