Kuyambitsa UV ndi UV LED ntchito
1. Chiyambi cha UV
Kutalika kwa mafunde a UV kumachokera ku 10nm mpaka 400nm, ndipo amagawidwa m'mafunde osiyanasiyana: curve yakuda ya UV (UVA) mu 320 ~ 400nm;Erythema ultraviolet kunyezimira kapena chisamaliro (UVB) mu 280 ~ 320nm;Kutsekereza kwa Ultraviolet (UVC) mu gulu la 200 ~ 280nm;Kwa ozone ultraviolet curve (D) mu 180 ~ 200nm wavelength.
2. Mawonekedwe a UV:
2.1 Mawonekedwe a UVA
Mafunde a UVA ali ndi malowedwe amphamvu omwe amatha kulowa m'magalasi owonekera kwambiri ndi pulasitiki.Kuwala kwa 98% UVA kumapanga kuwala kwa dzuwa kumatha kulowa mu ozone layer ndi mitambo ndikufika padziko lapansi.UVA imatha kutsogolera dermis ya khungu, ndikuwononga ulusi wotanuka ndi ulusi wa collagen ndi khungu lathu.Kuwala kwa UV komwe kutalika kwake kumakhala pafupifupi 365nm kumatha kugwiritsidwa ntchito poyesa, kuzindikira kwa fluorescence, kusanthula mankhwala, kuzindikiritsa mchere, kukongoletsa siteji ndi zina zotero.
2.2 Mawonekedwe a UVB
Mafunde a UVB amakhala ndi malo apakati, ndipo gawo lake lalifupi lalitali limatengedwa ndi galasi lowonekera.Kuwala kwa dzuwa, kuwala kwa UVB kumapanga dzuwa lomwe limatengedwa kwambiri ndi ozoni wosanjikiza, ndipo ndi ochepera 2% okha omwe amatha kufika padziko lapansi.M'chilimwe ndi masana adzakhala makamaka amphamvu.Ma radiation a UVB amakhala ndi erythema m'thupi la munthu.Ikhoza kulimbikitsa mapangidwe a mineral metabolism ndi vitamini D m'thupi, koma nthawi yayitali kapena kuwonetseredwa mopitirira muyeso kumatha kuwononga khungu.Mafunde apakati adagwiritsidwa ntchito pozindikira mapuloteni a fulorosenti komanso kafukufuku wambiri wachilengedwe, ndi zina zambiri.
2.3 mawonekedwe a gulu la UVC
Mafunde a UVC ali ndi malowedwe ofooka kwambiri, ndipo sangathe kulowa m'magalasi owoneka bwino ndi pulasitiki.Kuwala kwa UVC kumapanga kuwala kwadzuwa kumatengedwa kwathunthu ndi ozone layer.Kuvulaza kwa ma radiation a Shortwave ndi kwakukulu kwambiri, ma radiation akanthawi kochepa amatha kutentha khungu, mphamvu yayitali kapena yayitali imatha kuyambitsa khansa yapakhungu.
3. UV LED ntchito munda
Mu ntchito za msika wa UVLED, UVA ili ndi gawo lalikulu kwambiri la msika, mpaka 90%, ndipo ntchito yake imaphatikizapo kuchiritsa kwa UV, msomali, mano, inki yosindikizira, ndi zina zotero. Kuphatikiza apo, UVA imatumizanso kuunikira kwamalonda.
UVB ndi UVC amagwiritsidwa ntchito makamaka pochotsa, kuthira tizilombo toyambitsa matenda, mankhwala, kuwala, ndi zina zotero. UVB imayikidwa patsogolo pa chithandizo chamankhwala, ndipo UVC ndi yotseketsa.
3.1 njira yochiritsira kuwala
Zomwe zimagwiritsidwa ntchito ndi UVA ndi kuchiritsa kwa UV ndi kusindikiza kwa inkjet ya UV ndipo kutalika kwake ndi 395nm ndi 365nm.Kugwiritsa ntchito kuwala kwa UV LED kuphatikizidwira pochiritsa zomatira za UV zomwe zili pachiwonetsero, zamankhwala zamagetsi, zida ndi mafakitale ena;Zovala zochizira UV zimakhala ndi zida zomangira, mipando, zida zapanyumba, magalimoto ndi mafakitale ena opangira zokutira UV;mafakitale osindikizira ndi kulongedza inki ya UV;
Pakati pawo, mafakitale a UV LED panels akhala otentha.Ubwino waukulu ndikuti ukhoza kupereka palibe formaldehyde chilengedwe chitetezo bolodi, ndi 90% kupulumutsa mphamvu, zokolola zambiri, kukana kukwapula ndalama, mabuku phindu la ubwino zachuma.Izi zikutanthauza kuti msika wamachiritso a UV LED ndizomwe zimagwiritsidwa ntchito komanso msika wonse wozungulira.
3.2 gawo lopangira utomoni wopepuka
Utoto wochizira UV umapangidwa makamaka ndi oligomer, crosslinking agent, diluent, photosensitizer ndi zina zapadera.Ndi crosslinking reaction ndi machiritso mphindi.
Pansi pa kuyatsa kwa kuwala kwa UV LED kuchiritsa, nthawi yochiritsa ya utomoni wochiritsika ndi yaifupi kwambiri kotero kuti sifunika masekondi 10 ndipo imathamanga kwambiri kuposa nyali yachikhalidwe ya UV mercury pa liwiro.
3.3.Malo azachipatala
Kuchiza pakhungu: Kutalika kwa UVB ndi njira yofunika kwambiri yogwiritsira ntchito matenda a khungu, omwe ndi ultraviolet phototherapy applications.
Asayansi anapeza kuti pafupifupi 310nm wavelength ultraviolet cheza ali amphamvu shading zotsatira pakhungu, imathandizira kagayidwe khungu, kusintha khungu kukula mphamvu, amene angakhale othandiza pa matenda a vitiligo, pityriasis rosea, polymorphous dzuwa zidzolo, aakulu actinic dermatitis, kotero mu makampani azaumoyo, ultraviolet phototherapy yakhala ikugwiritsidwa ntchito kwambiri pakadali pano.
Zida zamankhwala: Zomatira za UV zomatira zathandizira kuti zida zachipatala zizilumikizana mosavuta.
3.4.Kutseketsa
UVC gulu ndi lalifupi wavelengths wa ultraviolet ray, mphamvu mkulu, akhoza kuwononga tizilombo mu nthawi yochepa thupi (monga mabakiteriya, kachilombo, spores tizilombo toyambitsa matenda) DNA (deoxyribonucleic acid) mu maselo kapena RNA (ribonucleic acid), dongosolo maselo. wa selo sangathe kusinthika, mabakiteriya ndi mavairasi amataya mphamvu yodzibwereza yokha, kotero gulu la UVC lingagwiritsidwe ntchito kwambiri pazinthu monga madzi, kutseketsa mpweya.
Ntchito zina zakuya za UV pamsika zomwe zilipo pano ndi monga choyezera chakuya cha uv cha LED, chowumitsa mswachi chakuya cha ultraviolet, chotsukira ma lens a UV LED, kutsekereza mpweya, madzi oyera, kutsekereza chakudya komanso kutsekereza pamwamba.Ndikusintha kwachitetezo cha anthu komanso chidziwitso chaumoyo, kufunikira kwa zinthuzo kudzasinthidwa kwambiri, kuti apange msika waukulu.
3.5.Malo ankhondo
UVC wavelength ndi wakhungu la ultraviolet wavelengths, kotero ili ndi ntchito yofunika mu usilikali, monga mtunda waufupi, kusokoneza kulankhulana kwachinsinsi ndi zina zotero.
3.6.Fakitale yamafakitale
Kulima kopanda dothi kosavuta kumapangitsa kuti zinthu zapoizoni zizichulukira, komanso kulima gawo lapansi muzakudya zam'mizu ndi mankhusu a mpunga zitha kunyonyotsoka ndi TiO2 chithunzi chothandizira, kuwala kwadzuwa kumakhala ndi 3% ya kuwala kwa UV, zida zovundikira monga galasi fyuluta kuposa 60%, angagwiritsidwe ntchito mkati mwa maofesi;
Anti-nyengo masamba yozizira otsika kutentha monga otsika dzuwa ndi osauka bata, sangathe kukwaniritsa zofunikira za malo masamba fakitale kupanga.
3.7.Malo ozindikiritsa miyala yamtengo wapatali
Mumitundu yosiyana ya miyala yamtengo wapatali, mitundu yosiyana ya mtundu womwewo wa miyala yamtengo wapatali ndi makina amtundu womwewo, imakhala yosiyana ndi maonekedwe a UV-yowoneka.Titha kugwiritsa ntchito UV LED kuzindikira miyala yamtengo wapatali ndikusiyanitsa miyala yamtengo wapatali yachilengedwe ndi miyala yamtengo wapatali yopangira, komanso kusiyanitsa miyala yachilengedwe ndi kukonza miyala yamtengo wapatali.
3.8.Kuzindikira ndalama zamapepala
Ukadaulo wozindikiritsa wa UV umayesa makamaka chizindikiro cha fulorosenti yotsutsana ndi zinthu zabodza komanso kuyanika kosayankhula kwamanoti pogwiritsa ntchito fulorosenti kapena sensa ya UV.Imatha kuzindikira zolemba zambiri zabodza (monga kuchapa, kutsuka, ndi kumata ndalama zamapepala).Tekinolojeyi idayamba kale kwambiri ndipo ndiyofala kwambiri.
