1. UV ndi chiyani?

Choyamba, tiyeni tionenso lingaliro la UV.UV, mwachitsanzo, ultraviolet, mwachitsanzo, ndi mafunde a electromagnetic okhala ndi kutalika kwapakati pa 10 nm ndi 400 nm.UV m'magulu osiyanasiyana amatha kugawidwa mu UVA, UVB ndi UVC.

UVA: yokhala ndi utali wautali kuchokera ku 320-400nm, imatha kulowa m'mitambo ndi magalasi m'chipindamo ndi galimoto, kulowa mkati mwa khungu ndikuyambitsa kutentha.UVA ikhoza kugawidwa mu uva-2 (320-340nm) ndi UVA-1 (340-400nm).

UVB: kutalika kwake kuli pakati, ndipo kutalika kwake kuli pakati pa 280-320nm.Idzayamwa ndi ozoni, kuchititsa kutentha kwa dzuwa, khungu lofiira, kutupa, kutentha ndi kupweteka, ndi matuza kapena kusweka kwambiri.

UVC: kutalika kwake kuli pakati pa 100-280nm, koma kutalika kwa mafunde pansi pa 200nm ndi vacuum ultraviolet, kotero imatha kuyamwa ndi mpweya.Chifukwa chake, kutalika komwe UVC imatha kuwoloka mlengalenga ndi pakati pa 200-280nm.Pamene kutalika kwake kwafupikitsa kumakhala koopsa kwambiri.Komabe, ikhoza kutsekedwa ndi ozone layer, ndipo pang’ono chabe ndiyo idzafika padziko lapansi.

2. Mfundo yotsekereza UV?

UV amatha kuwononga DNA (deoxyribonucleic acid) kapena RNA (ribonucleic acid) ya tinthu tating'onoting'ono, kotero kuti mabakiteriya amafa kapena sangathe kuberekana, kuti akwaniritse cholinga choletsa kubereka.

3. Gulu lotseketsa UV?

Malinga ndi kunena kwa International ultraviolet Association, “gawo la ultraviolet spectrum (gawo ‘lotsekereza’) limene lili lofunika kwambiri popha tizilombo toyambitsa matenda m’madzi ndi mpweya ndi mmene DNA (RNA) imayamwa ndi mavairasi ena.Gulu lotseketsa ili ndi pafupifupi 200-300 nm ".Zimadziwika kuti kutalika kwa njira yotsekera kumafikira kupitilira 280nm, ndipo tsopano kumadziwika kuti kumafikira 300nm.Komabe, izi zingasinthenso ndi kafukufuku wambiri.Asayansi atsimikizira kuti kuwala kwa ultraviolet kokhala ndi mafunde apakati pa 280nm ndi 300nm kutha kugwiritsidwanso ntchito potsekereza.

4. Kodi kutalika kwa mafunde koyenera kwambiri kotsekera ndi kotani?

Pali kusamvetsetsa kuti 254 nm ndiye mawonekedwe abwino kwambiri oletsa kutseketsa, chifukwa kutalika kwamphamvu kwa nyali ya mercury yotsika kwambiri (yomwe imatsimikiziridwa ndi physics ya nyali) ndi 253.7 nm.Kwenikweni, monga tafotokozera pamwambapa, mitundu ina ya wavelengths imakhala ndi bactericidal effect.Komabe, nthawi zambiri amawona kuti kutalika kwa mafunde a 265nm ndikwabwino kwambiri, chifukwa kutalika kwa mafundeku ndiye nsonga ya mayamwidwe a DNA.Chifukwa chake, UVC ndiye gulu loyenera kwambiri pakulera.

5. Chifukwa chiyani mbiri idasankha UVCLED?

M'mbiri, nyali ya mercury inali njira yokhayo yochotsera ma UV.Komabe, miniaturization yaUVC LEDzigawo zimabweretsa malingaliro ochulukirapo pazomwe zikugwiritsidwa ntchito, zambiri zomwe sizingachitike ndi nyali zachikhalidwe za mercury.Kuphatikiza apo, UVC yotsogolera ilinso ndi zabwino zambiri, monga kuyambika mwachangu, nthawi zololeka zosinthika, magetsi opezeka ndi batire ndi zina zotero.

6. UVC LED ntchito zochitika?

Kutsekereza pamwamba: malo omwe anthu ambiri amakumana nawo pafupipafupi monga zida zamankhwala, zida za amayi ndi ana, chimbudzi chanzeru, firiji, kabati yapa tableware, bokosi losungira mwatsopano, zinyalala zanzeru, kapu ya thermos, handrail escalator ndi batani lamakina ogulitsa matikiti;

Kutsekereza madzi akadali: thanki lamadzi la choperekera madzi, chonyowa ndi chopangira ayezi;

Kutsekereza madzi oyenda: gawo lotseketsa madzi oyenda, choperekera madzi akumwa mwachindunji;

Kuchotsa mpweya: choyezera mpweya, choziziritsa mpweya.

7. Kodi kusankha UVC LED?

Ikhoza kusankhidwa kuchokera ku magawo monga mphamvu ya kuwala, kutalika kwa nsonga, moyo wautumiki, ngodya yotulutsa ndi zina zotero.

Mphamvu ya kuwala: Mphamvu ya kuwala ya UVC LED yomwe ikupezeka pamsika wapano imachokera ku 2MW, 10 MW mpaka 100 MW.Mapulogalamu osiyanasiyana ali ndi zofunikira zosiyana za mphamvu.Nthawi zambiri, mphamvu ya kuwala imatha kufananizidwa ndikuphatikiza mtunda wa waya, kufunikira kwamphamvu kapena kufunikira kokhazikika.Kutalikira kwa mtunda wa kuwala, kumafuna mphamvu kwambiri, komanso mphamvu ya kuwala yomwe imafunika.

Kutalika kwa nsonga: monga tafotokozera pamwambapa, 265nm ndiye kutalika kwabwino kwambiri kwa njira yolera yotseketsa, koma poganizira kuti pali kusiyana pang'ono pamtengo wokwanira wa kutalika kwapamwamba pakati pa opanga, kwenikweni, mphamvu ya kuwala ndiyo index yofunikira kwambiri yoyezera kutseketsa bwino.

Moyo wautumiki: lingalirani za kufunikira kwa moyo wautumiki molingana ndi nthawi yautumiki wa mapulogalamu enaake, ndikupeza ma UVC otsogola abwino kwambiri, omwe ndi abwino kwambiri.

Kuwala kotulutsa ngodya: kuwala kotulutsa kowala kwa mikanda yopangidwa ndi lens ya ndege nthawi zambiri kumakhala pakati pa 120-140 °, ndipo mbali yowala yopangidwa ndi mandala ozungulira imatha kusinthika pakati pa 60-140 °.M'malo mwake, zilibe kanthu kuti mbali yayikulu yotulutsa ya UVC LED yasankhidwa bwanji, ma LED okwanira amatha kupangidwa kuti azitha kubisa malo ofunikira.M'malo osakhudzidwa ndi njira yotseketsa, kagawo kakang'ono ka kuwala kumapangitsa kuti kuwala kuchuluke kwambiri, kotero kuti nthawi yotseketsa imakhala yayifupi.
