EFG mandala safiro chubu lalikulu kunja awiri Kutentha kwambiri ndi kukana kuthamanga
Machubu a safiro amapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito m'malo ovuta kwambiri pomwe zida zina zitha kulephera. Ikhoza kupirira kutentha kwakukulu, dzimbiri, ndi kuvala, zomwe zimapangitsa kuti zikhale zofunikira pa ntchito monga machubu a ng'anjo, machubu otetezera a thermocouple, ndi masensa apamwamba komanso otentha kwambiri.
Kuphatikiza pa mawonekedwe ake amakina ndi matenthedwe, mawonekedwe a safiro owoneka bwino m'mawonekedwe owoneka bwino komanso pafupi ndi infrared amapangitsa kuti ikhale yothandiza pakugwiritsa ntchito komwe kumafunikira mwayi wofikira, monga makina a laser, zida zowunikira, ndi zipinda zofufuzira zapamwamba.
Ponseponse, machubu a safiro amayamikiridwa chifukwa chophatikiza mphamvu zamakina, kukana kwamafuta, komanso kuwonekera kwa kuwala, zomwe zimawapanga kukhala magawo osunthika pamafakitale osiyanasiyana ndi sayansi.
Katundu wa safiro chubu
- Kutentha kwabwino kwambiri komanso kukana kukanikiza: chubu chathu cha safiro chimagwiritsidwa ntchito kutentha kwambiri mpaka 1900 ° C.
- Kulimba kwambiri komanso kulimba kwake: Kulimba kwa chubu chathu cha safiro kumafika ku Mohs9, ndikulimba kolimba.
- Zopanda mpweya kwambiri: Chubu chathu cha safiro chimapangidwa munjira imodzi yokhala ndi ukadaulo wa eni ake ndipo ndi 100% yopanda mpweya, imalepheretsa kulowa kwa gasi wotsalira komanso kugonjetsedwa ndi dzimbiri lamafuta.
- Malo ambiri ogwiritsira ntchito: Chubu chathu cha safiro chingagwiritsidwe ntchito pazida zowunikira zosiyanasiyana ndipo chimatha kufalitsa kuwala kowoneka, infrared kapena ultraviolet, ndipo chimagwiritsidwa ntchito ngati cholowa m'malo mwa quartz, alumina ndi silicon carbide mu semiconductor processing applications.
