Tagar Sapphire Don Tanderun Zazzabi
A lokacin amfani da tanderun masana'antu da ɗakunan ajiya, taga tashar kallo za a fuskanci matsanancin matsin lamba da zafin jiki mai aiki.Don tabbatar da amincin masu gwaji, taga tashar kallo dole ne ta kasance mai ƙarfi, abin dogaro, juriya mai zafi, kuma yana da kyawawan kaddarorin gani.Sapphire na roba abu ne mai kyau a matsayin taga tashar kallo.
Sapphire yana da fa'idar ƙarfin ƙarfinsa: yana iya jure matsa lamba kafin fashewa.Sapphire yana da ƙarfin matsi na kusan 2GPa.Sabanin haka, ƙarfe yana da ƙarfin matsa lamba na 250 MPa (kusan sau 8 ƙasa da sapphire) kuma gilashin gorilla (™) yana da ƙarfin matsa lamba na 900 MPa (kasa da rabin sapphire).Sapphire, a halin yanzu, yana da kyawawan kaddarorin sinadarai kuma ba shi da ƙarfi ga kusan dukkanin sinadarai, yana sa ya dace da inda kayan lalata suke.Yana da ƙarancin ƙarancin thermal, 25 W m'(-1) K ^ (-1), da ƙarancin haɓakar haɓakar thermal na 5.8 × 10 ^ 6 / C: babu nakasawa ko haɓaka yanayin zafi a babba ko babba. yanayin zafi.Duk abin da kuka ƙirƙira, zaku iya tabbatar da girmansa iri ɗaya da haƙuri a mita 100 a ƙarƙashin teku ko 40K a cikin kewayawa.
Mun yi amfani da waɗannan halaye na ƙarfi da tagogi masu jurewa a cikin aikace-aikacen abokin ciniki, gami da ɗakuna masu zafi da tanderun zafin jiki.
Sapphire taga don tanderun yana da kyakkyawan watsawa a cikin kewayon 300nm zuwa 5500nm (wanda ke rufe ultraviolet, bayyane da wuraren infrared) da kololuwa a ƙimar watsa kusan 90% a 300nm zuwa 500 nm raƙuman ruwa.Sapphire abu ne mai jujjuyawa sau biyu, don haka yawancin kaddarorinsa na gani za su dogara ne akan daidaitawar crystal.A kan kusurwoyinsa na yau da kullun, ginshiƙi mai jujjuyawa yana jeri daga 1.796 a 350nm zuwa 1.761 a 750nm, kuma koda yanayin zafi ya canza sosai, yana canzawa kaɗan kaɗan.Saboda kyakkyawar watsa haske da kewayon tsayinsa, muna yawan amfani da taga sapphire a cikin ƙirar ruwan tabarau na infrared a cikin tanda lokacin da mafi yawan gilashin bai dace ba.
Anan akwai dabarar Lissafin Ƙwarewa na kauri don taga tashar kallon sapphire:
Th=√( 1.1 x P x r² x SF/MR)
inda:
Th=Kaurin taga(mm)
P = Tsarin amfani da matsin lamba (PSI),
r = Radius mara tallafi (mm),
SF = Fa'idar Tsaro (4 zuwa 6) (wanda aka ba da shawara, na iya amfani da wasu dalilai),
MR = Modulus na rupture (PSI).Sapphire kamar 65000PSI
Misali, taga Sapphire mai diamita 100 mm da radius mara goyon baya 45 mm da aka yi amfani da shi a cikin yanayi tare da bambancin Matsi na yanayi 5 yakamata ya kasance da kauri na ~3.5mm (fasali na aminci 5).
