Iyini imisebe ephezulu ye-UV?

Ngokwesayensi,Ukuqina okuphezulu kwe-UV Imisebe yi-UV-A, UV-B, noma i-UV-C UV ukukhanya okunamandla aphezulu e-photon. Ibhendi le-UV-C livame ukusetshenziswa ezinhlelweni ezinamandla kakhulu.

Amapharamitha ebaluleke kakhulu ezobuchwepheshe yilezi:

• Ubude be-UV bemisebe phakathi kwe-100-400nm

•Ukuqina kwebhendi ye-UV-C okufanele ihlanjululwe inzalo (200280nm).

• I-UV photon flux, okuyisilinganiso sokukhishwa kwe-photon.

•Ukuqina kwe-UV ye-radiometric, ku-mW / cm 2.

•Ukusatshalaliswa kwamandla kwe-UV ye-Spectral, okukhombisa ukusatshalaliswa kwamandla.

Lokhu kwenza i-UV ibe uhlelo olulawulwayo lwemisebe ye-UV kagesi, hhayi nje ukukhanya.

Ukuqina okuphezulu kwe-UV: Ukunemba kwezimboni nokuvala inzalo

Ukuqina okuphezulu kwe-UV Imisebe ye-ultraviolet enamandla esetshenziselwa izimboni zesayensi nezokwelapha. Inikeza ukukhishwa kwamandla aphezulu kokukhanya kwe-ultraviolet okungasetshenziswa ukunika amandla ukusabela kwe-photochemical, inzalo, kanye nezinqubo zokuphulukisa ngokusebenza kahle okuphezulu.

• Ukukhanya kwe-UV akuseyona umqondo welabhoratri ezimbonini zanamuhla. Kuye kwavela njengensika yokukhiqiza, inzalo yokunakekelwa kwezempilo, kanye nobunjiniyela bomhlaba. Lobu buchwepheshe buchaza izinqubo ezihlanzekile, ezisheshayo futhi eziqondile, ukuqala ngezinhlelo zokukhanya ze-UV zezimboni futhi zifike ezilambu eziphezulu ze-UV.
• Kuyinto ethandwa kakhulu ngesizathu esilula. Inikeza izinga elilawulwayo le-UV irradiance, okusho ukuthi amandla angasetshenziswa ngokunembile lapho kudingeka khona ngaphandle kokuxhumana kwemishini.

Umshini wokusebenza kobuchwepheshe obuphezulu be-UV

Uhlelo ngokuyisisekelo lusekelwe ekudlulisweni kwe-photonic kwamandla e-UV. Lapho ushaya indawo, ama-photon e-UV aphula izibopho zamangqamuzana futhi abangele ukusabela kwamakhemikhali noma kwezinto eziphilayo.

Lokhu kuklanyelwe ngokucophelela ezinhlelweni zezimboni ngokuthi:

•Ukulawulwa kwamandla okukhishwa kwe-UV.

• Ukulungiswa kokuhlushwa komthamo we-UV

• UV amandla ukuminyana ukulawula optical.

•Ukulinganisa kwencazelo ephezulu ye-UV irradiance.

Njengomzekeliso, i-DNA ye-microbial ezinhlelweni zokuvala inzalo ithatha ama-photon e-UV-C. Lokhu kubangela ukungasebenzi kwamagciwane ngomthamo we-UV, ukuvimbela ukuphindaphinda. Ezinhlelweni zokuphulukisa, amandla e-UV enza ukuthi amaketanga e-polymer aqine ngokushesha ukudala ukumbozwa okuqinile.

Izinhlelo eziphezulu ze-UV embonini

IUkuqina okuphezulu kwe-UV Ubuchwepheshe buthandwa kakhulu ezimbonini ngoba bunembile futhi bushesha.

1. Izinhlelo ze-UV Curing and Coating

Ukuqina kwamandla okuphulukisa kwe-UV kubalulekile ekukhiqizeni. Isetshenziswa ku:

• Umthamo we-UV we-sterilization yezokwelapha.

•Ukuhlanzwa komoya kwe-UV.

• Ukulawulwa kokuqina kwe-UV kokuhlanzwa kwamanzi.

Izinhlelo ezinjalo ziqinisekisa izinhlelo zokubulala amagciwane ze-UV eziphezulu ukuze zisebenze kahle ngokumelene namabhaktheriya namagciwane.

3. Ukuhlanza amanzi nomoya

Ubunjiniyela bemvelo,Ukuqina okuphezulu kwe-UV Inzalo isetshenziselwa ukuqeda ama-microorganisms ngaphandle kwamakhemikhali.

Izinzuzo ezibalulekile:

• Ukuhlanzwa okungenamakhemikhali

•Ayikho insalela eshiywe ngemuva.

• Izinhlelo zokusebenza eziqhubekayo

Lokhu kwenziwa ngokusebenzisa amazinga okulawulwayo we-UV wamandla kanye nesikhathi sokuchayeka.

Ukuqina okuphezulu kwe-UV LED vs Isibani sendabuko se-UV

Ukushintshwa kwezibani zendabuko ngezinhlelo ze-LED kungenye yezinguquko ezinkulu zobuchwepheshe.

Izibani zendabuko ze-UV

• Isizukulwane sokushisa okuphezulu

• UV photon flux

• Ukusatshalaliswa kwamandla kwe-UV

Lokhu kuqinisekisa ukusebenza okufanayo ezinhlelweni zezimboni.

I-UV enamandla ekukhiqizeni kwanamuhla

Ubuchwepheshe be-UV bubalulekile ezimbonini ukuhlinzeka ngokunemba kwezinqubo.

Ukusetshenziswa kokukhiqiza:

• Ukuphulukisa ukuchayeka kwe-UV kwe-resin ku-elekthronikhi.

• UV enamathela ukwelashwa ebusweni

• Amandla e-UV ekuphenduleni kwe-photochemical ekusetshenzisweni kwezinto zokwakha.

•Ukukhiqizwa ngobuningi kwezimboni ze-UV irradiation systems.

Ijubane liyinzuzo ebaluleke kakhulu. Lokho okwakudinga imizuzu noma amahora manje kuzodinga imizuzwana.

Ukulawulwa kokuvezwa kanye namazinga okuphepha

Yize ubuchwepheshe be-UV bunamandla kakhulu, udaba lokuphepha lubaluleke kakhulu.

Ukucatshangelwa okuyinhloko kokuphepha yilezi:

• Ukuchayeka emisebeni ye-UV kunciphisa ukuhambisana.

Izindinganiso zokuphepha ze-UV ze-photobiological.

• Ukuvikelwa kwe-UV kwamehlo nesikhumba.

•Imihlahlandlela yokuvezwa kwe-UV emsebenzini.

• Ukuvikelwa kwemisebe ye-UV ezindaweni zokusebenza.

Izinhlelo ezinamandla kakhulu kufanele ngaso sonke isikhathi zibe ngendlela yokuthi ukuchayeka kulawulwe ukuvimbela amazinga ayingozi okuqina kwe-UV.

Isibani sokuhlola se-UV LED embonini

Ezimbonini lapho kudingeka khona ukuhlolwa ngokunemba, kusetshenziswa amathuluzi e-UV aphathekayo. Isibani sokuhlola se-UV LED singesinye sezixazululo ezithuthukisiwe ezisetshenziselwa ukwenza ukuhlolwa okungabhubhisi nokuhlolwa komhlaba.

Izinzuzo ezibalulekile:

• Ukukhiqizwa okuqinile kokukhanya kwe-UV ukuthuthukisa ukuhlolwa.

• I-ergonomic futhi ephathekayo.

• Ukulawulwa kwe-wavelength okuzinzile

• Ukuqina okuhle kokukhishwa kwe-UV ukuthola amaphutha.

• Ilungele kakhulu izilungiselelo zokuhlolwa kwezimboni.

Lo mkhiqizo ukhombisa iqiniso lokuthi amamojula e-UV LED aya ngokuya eba yisidingo ezinhlelweni zanamuhla zokulawula ikhwalithi.

Izizathu zokuthi kungani izimboni zethemba izixazululo ze-UVNDT

Zenzelwe ukusekela:

• Izinhlelo zokuphulukisa ze-UV zokusebenza okuphezulu.

• Amathuluzi wokuhlola ngokunemba

• Imishini ye-UV ehlala isikhathi eside futhi yokonga amandla.

Ngokufunwa okwandayo kwe-automation, izixazululo ze-UVNDT zinikeza ukuzinza nokunemba kwezobuchwepheshe.

Izinzuzo zobuchwepheshe obuphezulu be-UV

Ukuthuthukiswa kobuchwepheshe be-UV kusekelwa yizinzuzo ezisobala:

• Isivinini sokucubungula esisheshayo

• Ukunemba okukhulu ekulawulweni kwamandla.

• Inzalo engenamakhemikhali
