Uma abathengi bethenga izingubo zasebusika ezifudumele, bavame ukuhlangana neziqubulo ezinjengokuthi: “Ukuzifudumeza okukude kwe-infrared”, “Isikhumba esifudumala kude ne-infrared”, “I-infrared ekude igcina ifudumele”, njll. Kusho ukuthini ngempela “i-infrared ekude”?ukusebenza?Kwenziwa kanjanitholangabe indwangu inakhoizakhiwo ze-infrared?
Yini i-infrared kude?
Imisebe ye-infrared iwuhlobo lwamaza okukhanya ubude bayo begagasi bufushane kunamaza omsakazo futhi made kunokukhanya okubonakalayo.Imisebe ye-infrared ayibonakali ngeso lenyama.Ububanzi be-wavelength bemisebe ye-infrared bubanzi kakhulu.Abantu bahlukanisa imisebe ye-infrared kumabanga ahlukene wamaza abe yizifunda eziseduze ne-infrared, mid-infrared kanye ne-far-infrared.Imisebe ye-infrared ekude inamandla anamandla angena futhi akhipha imisebe, futhi inokulawula okuphawulekayo kwezinga lokushisa kanye nemiphumela yokuzwakala kwemisindo.Zithathwa kalula yizinto futhi ziguqulelwe amandla angaphakathi ezinto.
Ungabona kanjani ukuthi izindwangu zinezakhiwo ze-infrared?
I-GB/T 30127-2013"Ukutholwa Nokuhlolwa Kokusebenza Kwezindwangu Ezikude Ne-infrared" kusebenzisa izinto ezimbili "zokukhipha ukukhanya kwe-infrared" kanye "nokwenyuka kwezinga lokushisa lemisebe ye-infrared" ukuze kuhlolwe ukuthi izindwangu zinezakhiwo ze-infrared ezikude.
I-far-infrared emissivity ukubeka ipuleti elimnyama elijwayelekile kanye nesampula kupuleti elishisayo ngokulandelana, futhi ulungise izinga lokushisa elingaphezulu le-hot plate ngokulandelana ukuze lifinyelele izinga lokushisa elicacisiwe;i-blackbody ejwayelekile ikalwa ngokuhlukana kusetshenziswa isistimu yokulinganisa imisebe ye-infrared ekude enobubanzi bokusabela okubukekayo obumboza ibhendi engu-5 μm ~ 14 μm.Ubukhulu bemisebe ngemva kokuba ipuleti nesampula zimbozwe kupuleti elishisayo kufinyelela ukuzinza, futhi ukukhishwa kwe-infrared ekude yesampula kubalwa ngokubala isilinganiso sokuqina kwemisebe yesampula kanye nepuleti elijwayelekile le-blackbody.
Isilinganiso sokunyuka kwezinga lokushisa siwukukala ukukhuphuka kwezinga lokushisa endaweni yokuhlola yesampula ngemva kokuba umthombo wemisebe ye-infrared kude ukhanyise isampula ngamandla okukhanya angaguquki isikhathi esithile.
Hlobo luni lwezindwangu ezingakalwa njengezinezindawo ze-infrared?
Kumasampuli avamile, uma i-infrared emissivity yesampula ingekho ngaphansi kuka-0.88, futhi izinga lokushisa le-infrared elikude lingekho ngaphansi kuka-1.4°C, isampuli inezinto ze-infrared ezikude.
Kumasampuli axegayo anjengama-flakes, ama-nonwovens, nama-piles, ukukhishwa kwe-infrared kude akukho ngaphansi kuka-0.83, futhi izinga lokushisa lemisebe ye-infrared elikude alikho ngaphansi kuka-1.7°C.Isampula inezindawo ze-far-infrared.
Kuyaqapheleka ukuthi ukugeza okuningi nakho kunomthelela othile ekusebenzeni okude kwe-infrared.Uma okungenhlaizidingo zenkombazisahlangatshezwana ngemuva kokugeza okuningi, isampula lithathwa njengomkhiqizo onaloukumelana nokugezaukusebenza kwe-infrared.
