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.
Kuyaphawuleka ukuthi ukugeza okuningi nakho kunomthelela othile ekusebenzeni kwe-infrared ekude. Uma okungenhlaizidingo zenkombazisahlangatshezwana ngemuva kokugeza okuningi, isampula lithathwa njengomkhiqizo onaloukumelana nokugezaukusebenza kwe-infrared.
