Mawindo a Sapphire owoneka bwino okhala ndi ma step holes a dia25.4×2.0mmt
Zambiri Zambiri
Makhalidwe a mankhwala a safiro ndi okhazikika kwambiri ndipo sawonongeka ndi ma acid ndi ma alkali. Kulimba kwa safiro ndi kwakukulu kwambiri, ndi kulimba kwa Mohs kwa 9, yachiwiri kuposa diamondi yolimba kwambiri. Ili ndi ma transmission abwino a kuwala, kutentha kwa kutentha komanso kutchinjiriza magetsi, mphamvu zabwino za makina ndi makina, ndipo ili ndi makhalidwe oletsa kuwonongeka ndi kukana kukokoloka kwa nthaka ndi mphepo. Kutentha kwakukulu kogwira ntchito ndi 1900℃.
Popeza zinthu zopangidwa ndi safiro zopangidwa ndi kristalo zapamwamba kwambiri zimakhala ndi kuwala kwabwino mu gulu la 170nm ~ 6000 nm, kuwala kwa infrared sikusinthasintha ndi kutentha, kotero zida zowunikira ndi mawindo owunikira opangidwa ndi safiro zopangidwa ndi pulasitiki ...
Makhalidwe ndi kugwiritsa ntchito safiro
1, Sapphire yokhala ndi magwiridwe antchito abwino kwambiri, imakhala zinthu zogwiritsidwa ntchito kwambiri za oxide substrate (zipangizo za substrate)
2, Zigawo zowunikira, galasi la wotchi, zenera lowunikira, zenera lozindikira ndi momwe limagwiritsidwira ntchito
3, chowunikira cha ulusi wa safiro ndi momwe chimagwiritsidwira ntchito
4, Zida zowala za safiro imodzi ya kristalo yotentha (yopepuka) ndi momwe imagwiritsidwira ntchito
