1. Ukwethulwa kwe-UV

Ubude be-UV busukela ku-10nm kuya ku-400nm, futhi buhlukaniswe ngama-wavelength ahlukene: i-black spot uv curve ye-(UVA) ku-320 ~ 400nm; imisebe ye-Erythema ultraviolet noma ukunakekelwa (UVB) ku-280 ~ 320nm; Ukuhlanza nge-Ultraviolet (UVC) ku-200 ~ 280nm band; Ukuya ku-ozone ultraviolet curve (D) ku-180 ~ 200nm wavelength.

2. Izici ze-UV:

2.1 Isici se-UVA

Amaza okukhanya e-UVA anokungena okunamandla okungangena engilazini nasepulasitikini okusobala kakhulu. Imisebe ye-UVA engaphezu kuka-98% eyakha ukukhanya kwelanga ingangena ongqimbeni lwe-ozone kanye namafu futhi ifinyelele ebusweni bomhlaba. I-UVA ingaqondisa i-dermis yesikhumba, futhi yonakalise imicu enwebekayo kanye nemicu ye-collagen kanye nesikhumba sethu. Ukukhanya kwe-UV okuphakathi kwayo okungama-365nm kungasetshenziswa ekuhlolweni, ekutholakaleni kwe-fluorescence, ekuhlaziyweni kwamakhemikhali, ekuhlonzeni amaminerali, ekuhlobiseni isiteji njalo njalo.

2.2 Isici se-UVB

Amaza okukhanya e-UVB anokungena okuphakathi nendawo, kanti ingxenye yawo yokukhanya okufushane izomuncwa yingilazi esobala. Ekukhanyeni kwelanga, imisebe ye-UVB yakha ilanga imuncwa kakhulu ungqimba lwe-ozone, futhi ngaphansi kuka-2% kuphela okungafinyelela ebusweni bomhlaba. Ehlobo nantambama iyoba namandla kakhulu. Imisebe ye-UVB inomphumela we-erythema emzimbeni womuntu. Ingakhuthaza ukwakheka kwe-metabolism yamaminerali kanye ne-vitamin D emzimbeni, kodwa ukuvezwa isikhathi eside noma ngokweqile kungathambisa isikhumba. Izansi eliphakathi lasetshenziswa ekutholeni amaprotheni e-fluorescent kanye nocwaningo olwengeziwe lwezinto eziphilayo, njll.

Izici zebhendi ye-UVC engu-2.3

Amaza okukhanya e-UVC anokungena okubuthakathaka kakhulu, futhi awakwazi ukungena engxenyeni enkulu yengilazi ecacile nepulasitiki. Imisebe ye-UVC yakha ukukhanya kwelanga okumuncwa ngokuphelele ungqimba lwe-ozone. Umonakalo wemisebe ye-ultraviolet ye-Shortwave mkhulu kakhulu, imisebe yesikhathi esifushane ingashisa isikhumba, amandla amade noma aphezulu angabangela umdlavuza wesikhumba.

3. Insimu yesicelo se-UV LED

Ezinhlelweni zemakethe ye-UVLED, i-UVA inesabelo esikhulu kunazo zonke emakethe, esifinyelela ku-90%, futhi ukusetshenziswa kwayo kuhilela kakhulu ukuphulukiswa kwe-UV, izinzipho, amazinyo, uyinki wokunyathelisa, njll. Ngaphezu kwalokho, i-UVA iphinde ingenise ukukhanya kwezentengiselwano.

I-UVB kanye ne-UVC zisetshenziswa kakhulu ekubulaleni amagciwane, ekubulaleni amagciwane, ekwelashweni ngokukhanya, njll. I-UVB inikezwa kuqala ukwelashwa kwezokwelapha, kanti i-UVC iwukubulala amagciwane.

3.1 uhlelo lokupholisa ukukhanya

Ukusetshenziswa okujwayelekile kwe-UVA ukuphrinta nge-UV kanye ne-UV inkjet kanti ubude be-wavelength obujwayelekile bungu-395nm kanye no-365nm. Ukusetshenziswa kokukhanya kwe-UV LED okufakwe kuma-glue e-UV anamathelayo aqukethe esikrinini sokubonisa, ezokwelapha ngogesi, emishinini nakwezinye izimboni; izembozo ze-UV ezisebenzisa i-UV ziqukethe izinto zokwakha, ifenisha, izinto zasekhaya, izimoto kanye nezinye izimboni zezembozo ze-UV ezisebenzisa i-UV; izimboni zokuphrinta nokupakisha i-UV ezisebenzisa i-UV;

Phakathi kwazo, imboni yamaphaneli e-UV LED isibe yindawo eshisayo. Inzuzo enkulu ukuthi ayikwazi ukunikeza ibhodi yokuvikela imvelo ye-formaldehyde, kanye nokonga amandla okungu-90%, isivuno esikhulu, ukumelana nokuklwebheka kwezinhlamvu zemali, inzuzo ephelele yezinzuzo zomnotho. Lokhu kusho ukuthi imakethe yokwelapha i-UV LED iwumkhiqizo wokusetshenziswa ophelele kanye nemakethe yomjikelezo wonke.

Insimu yokufaka i-resin ekhanyayo engu-3.2

I-resin elaphekayo ye-UV yakhiwe kakhulu yi-oligomer, i-agent yokuxhumanisa, i-diluent, i-photosensitizer kanye nenye into ethile. Iwukusabela kokuxhumanisa kanye nesikhathi sokupholisa.

Ngaphansi kokukhanya kokukhanya kwe-UV LED, isikhathi sokukhanya kwe-resin elaphekayo ye-UV sifushane kakhulu kangangokuthi asidingi imizuzwana eyi-10 futhi sishesha kakhulu kunesibani se-UV mercury sendabuko ngesivinini.

3.3. Insimu yezokwelapha

Ukwelashwa kwesikhumba: Ububanzi be-UVB buyindlela ebalulekile yokusebenzisa izifo zesikhumba, okungukuthi ukusetshenziswa kwe-ultraviolet phototherapy.

Ososayensi bathole ukuthi imisebe ye-ultraviolet engama-310nm ubude inemiphumela enamandla yokufiphaza esikhumbeni, isheshisa ukushintshwa kwesikhumba, ithuthukise amandla okukhula kwesikhumba, okungaba yimpumelelo ekwelapheni i-vitiligo, i-pityriasis rosea, ukuqubuka kwelanga okuguquguqukayo, i-dermatitis ye-actinic engapheli, ngakho-ke embonini yezempilo, i-ultraviolet phototherapy isetshenziswa kakhulu njengamanje.

Imishini yezokwelapha: I-glue ye-UV glue yenze kwaba lula ukuhlanganisa imishini yezokwelapha ngokuzenzakalela.

3.4. Ukubulala inzalo

Ibhendi ye-UVC ngamaza amafushane emisebe ye-ultraviolet, amandla aphezulu, ingabhubhisa amagciwane ngesikhathi esifushane umzimba (njengamabhaktheriya, igciwane, izinhlayiya ezibangela izifo) i-DNA (deoxyribonucleic acid) emaseli noma i-RNA (ribonucleic acid), isakhiwo sama-molecule esisele asikwazi ukuphinda sivuseleleke, amagciwane namagciwane alahlekelwa ikhono lokuziphindaphinda, ngakho-ke ibhendi ye-UVC ingasetshenziswa kabanzi emikhiqizweni efana namanzi, ukubulala amagciwane emoyeni.

Ezinye izinhlelo zokusebenza ze-UV ezijulile emakethe njengamanje zifaka phakathi i-LED deep UV portable sterilizer, i-LED deep ultraviolet brush sterilizer, i-UV LED lens cleaning sterilizer, i-air sterilizer, amanzi ahlanzekile, i-food sterilizer kanye ne-surface sterilizer. Ngokuthuthuka kokuphepha kwabantu kanye nokuqonda impilo yabo, isidingo semikhiqizo sizothuthukiswa kakhulu, ukuze kudalwe imakethe enkulu.

3.5. Insimu yezempi

Ubude be-UVC bungobamaza obuyimpumputhe be-ultraviolet, ngakho-ke bunokusetshenziswa okubalulekile empini, njengokuhamba ibanga elifushane, ukuphazamiseka kokuxhumana okuyimfihlo nokunye.

3.6. Ifayineli yefektri yesitshalo

Ukutshala okungenanhlabathi okuvalekile kungabangela ukuqongelela kwezinto ezinobuthi, futhi ukutshala i-substrate esixazululweni sezakhamzimba ukukhishwa kwezimpande kanye nemikhiqizo yokubola kwe-rice husk kungonakalisa yi-TiO2 photo-catalyst, imisebe yelanga iqukethe kuphela u-3% wokukhanya kwe-UV, izinto ezimboza izikhungo ezifana nesihlungi sengilazi ezingaphezu kuka-60%, zingasetshenziswa ngaphakathi kwezikhungo;

Imifino elwa nesizini ebusika inezinga lokushisa eliphansi njengoba ukusebenza kahle okuphansi kanye nokuzinza okubi, ayikwazi ukuhlangabezana nezidingo zezindawo zokukhiqizwa kwemifino efektri.

3.7. Insimu yokuhlonza amatshe ayigugu

Ezinhlotsheni ezahlukene zamatshe ayigugu, imibala ehlukene yohlobo olufanayo lwamatshe ayigugu kanye nendlela yokusebenza kombala ofanayo, ane-spectrum yokumuncwa ebonakalayo ye-UV ehlukile. Singasebenzisa i-UV LED ukuhlonza amagugu nokuhlukanisa amagugu athile emvelo kanye namatshe ayigugu okwenziwa, futhi sihlukanise amanye amatshe emvelo kanye nokucutshungulwa kwamagugu okwenziwa.

3.8. Ukuqashelwa kwemali yephepha

Ubuchwepheshe bokuhlonza i-UV buhlola kakhulu uphawu lokulwa nokukhwabanisa olukhanyayo kanye nokusabela kokukhanya okungabonakali kwemali yamaphepha ngokusebenzisa inzwa ye-fluorescent noma ye-UV. Ingakwazi ukubona iningi lamaphepha mbumbulu (njengokuwasha, ukufiphaza, kanye nemali yephepha yokunamathisela). Lobu buchwepheshe bathuthuka kusenesikhathi futhi buvame kakhulu.
