Factory Customized Precision Machining Sapphire
Sapphire ili ndi kuuma kwa Mohs 9, yachiwiri kwa diamondi, ndipo imakhala ndi mphamvu yokana kuvala. Nthawi yomweyo, imakhala ndi kukhazikika kwamankhwala abwino kwambiri ndipo imatha kukana dzimbiri pafupifupi zinthu zonse za asidi ndi zamchere. Komanso, pazipita kutentha kukana safiro ndi 2060 ℃. Chifukwa cha zabwino zomwe zili pamwambapa za safiro, safiro imagwiritsidwa ntchito pazida ndi zida, zomwe zimatha kusintha kwambiri moyo wautumiki ndikupirira madera osiyanasiyana ovuta.
Zigawo zolondola za safiro nthawi zambiri zimakhala ndi mawonekedwe ovuta komanso zofunikira zosindikizira. Titha kusintha mawonekedwe osiyanasiyana malinga ndi zojambula zamakasitomala. Tili ndi zida zodulira molondola, zopera, zopukutira ndi zoyesera kuti tiwonetsetse kuti chilichonse chikukwaniritsa zofunikira za makasitomala.
Njira Zazikulu Zopangira
Zinthu Zakuthupi
Sapphire ndi crystal aluminium oxide (Al2O3). Ndi imodzi mwazinthu zolimba kwambiri. Sapphire ili ndi mawonekedwe abwino opatsirana powonekera, komanso pafupi ndi mawonekedwe a IR. Imawonetsa mphamvu zamakina apamwamba, kukana kwamankhwala, kukhazikika kwamafuta komanso kukhazikika kwamafuta. Nthawi zambiri amagwiritsidwa ntchito ngati zida zazenera pagawo linalake monga ukadaulo wa danga pomwe kukankha kapena kukana kutentha kumafunika.
