Sapphire Window For High Temperature Furnace
Munguva yekushandiswa kwechoto cheindasitiri uye vacuum makamuri, hwindo rekuona richaiswa pasi pekumanikidzwa kwakanyanya uye tembiricha yekushanda.Kuti uve nechokwadi chekuchengetedza kwevanoedza, hwindo rekuona rinofanirwa kusimbiswa, rakavimbika, rinodzivirira tembiricha, zvakare rine yakanakisa optical zvivakwa.Synthetic safira chinhu chakanakira senge hwindo rekuona.
Safire ine mukana wesimba rayo rekumanikidza: inogona kumirisana nekumanikidza isati yaputika.Safire ine simba rekumanikidza rinosvika 2 GPa.Kusiyana neizvi, simbi ine simba rekumanikidza re250 MPa (inenge ka8 kashoma pane sapphire) uye gorilla girazi (™) ine simba rekumanikidza re900 MPa (isingasviki hafu yesafire).Sapphire, zvakadaro, ine yakanakisa makemikari zvimiro uye inert kune angangoita ese makemikari, ichiita kuti ive yakakodzera kune inoora zvinhu zviripo.Iyo ine yakaderera kwazvo yekupisa conductivity, 25 W m'(-1) K^(-1), uye yakaderera zvakanyanya kupisa kwekuwedzera kwemafuta e5.8 × 10 ^ 6 / C: hapana deformation kana kuwedzera kwemamiriro ekupisa kumusoro kana kumusoro. tembiricha.Chero dhizaini yako, unogona kuve nechokwadi kuti ine saizi yakafanana uye kushivirira pamamita zana pasi pegungwa kana 40K mukutenderera.
Isu takashandisa aya hunhu hwesimba uye mahwindo asingakweshe mukushandisa kwevatengi, kusanganisira vacuum chamber uye tembiricha yekupisa.
Window resafire rechoto rine kutapurirana kwakanaka kwazvo mu300nm kusvika 5500nm range (inovhara ultraviolet, inooneka uye infrared nzvimbo) uye inokwira pamateiro ekutapurirana angangoita 90% pa300 nm kusvika 500 nm wavelengths.Safire chinhu chakapetwa kaviri refractive, saka akawanda ayo optical zvimiro zvinoenderana nekristaro kutaridzika.Paaxis yayo yakajairika, iyo refractive index inotangira pa1.796 pa350nm kusvika 1.761 pa750nm, uye kunyangwe tembiricha ikachinja zvakanyanya, inochinja zvishoma.Nekuda kwekutapurirana kwakanaka kwechiedza uye kureba kwewavelength, isu tinowanzo shandisa hwindo resafire mune infrared lens dhizaini muchoto kana mamwe magirazi akajairika asina kukodzera.
Heino Chiitiko Kuverengera fomula yeukobvu hwesafire yekuona hwindo:
Th=√( 1.1 x P x r² x SF/MR)
kupi:
Th=Kukora kwehwindo(mm)
P = Dhizaini shandisa kudzvanywa (PSI),
r = radius isina kutsigirwa (mm),
SF = Chengetedzo chinhu (4 kusvika 6) (yakakurudzirwa huwandu, inogona kushandisa zvimwe zvinhu),
MR = Modulus yekuputika (PSI).Sapphire se65000PSI
Semuyenzaniso, hwindo reSapphire rine dhayamita 100 mm uye risingatsigirwe radius 45 mm rinoshandiswa munzvimbo ine Pressure musiyano we 5 atmosphere inofanirwa kuve neukobvu hwe ~3.5mm (safety factor 5).
