[Manja Omata Padziko Lonse] Ichi Ndi Chosaoneka Chomwe Chimakhudza Mphamvu ya UVLED Irradiation Effect

Tianhui wakumana ndi makasitomala ambiri pokambirana. Pambuyo pa gwero la kuwala kwa UVLED kuyatsa, pamwamba pa guluu kumamvekabe. Guluuyo atayesedwa kowononga, amapezeka kuti guluuyo wakhazikika, ndipo guluu lonse ndi guluu. Chakhala cholimba. Anthu ambiri atha kumvetsetsa kuti kuchulukitsitsa kwa kuwala kwa UVLED sikukwanira kutengera kumvetsetsa kwawo, ndipo wogulitsa guluu sangakhale wokwanira kutengera chidziwitso chaukadaulo. Kodi izi ndi zoona? Kwenikweni sichoncho. Apa tiyenera kudziwa kutsekereza kwa oxygen! Kutsekedwa kwa okosijeni kumatchedwanso inhibitory inhibitory. Pafupifupi zida zonse zochizira ma radiation ndi zolimbitsa thupi zimakhudzidwa ndi okosijeni mumlengalenga. Chifukwa chakuti mpweya wa okosijeni pamtunda ndi wapamwamba kwambiri, kuphatikizika kwa okosijeni nthawi zambiri kumapangitsa kuti gawo lapansi likhale lolimba, ndipo pamwamba pake sichimalimba. Kuyesaku kumatsimikizira kuti kwa varnish, mphamvu zomwe zimagwiritsidwa ntchito pochiritsa zokutira za 1um mumlengalenga ndizochulukirapo kuposa zokutira za 1UM za 1um wandiweyani wokutira (5um kuchokera pamwamba). Zotsatira za oxygen bargaining sizimangowonjezera nthawi yochiritsa ma radiation, komanso zimatha kuwononga ntchito yofunika kwambiri ya kuuma, kukana kwa abrasion, komanso kukana kuvulala kwapamwamba, monga kuuma, kukana abrasion, ndi kuvulala. Mtsinje wa zinthu zonse (ndiko kuti, dziko lokhazikika) ndi mzere umodzi, koma mamolekyu a okosijeni, malo ake okhazikika ndi mizere itatu, ndipo pali awiriawiri osafikirika amagetsi omwe ali mbali imodzi ya spin. . Chifukwa chake, zitha kuganiziridwa kuti mamolekyu okosijeni ndi ma radicals aulere awiri. Ngakhale mpweya wokha ndi wokhazikika ndipo sungathe kuchititsa mwachindunji kusakanikirana kwa acrylic pa kutentha kwakukulu, idzatsutsana ndi momwe ma radicals aulere amachitira kuti adye ma radicals aulere, potero amatulutsa mpweya wotseketsa agglomeration. Pali njira zambiri zochepetsera njira zotsekereza oxygen. Njira yakuthupi ndiyo kuthamangitsa mpweya m'dongosolo m'njira zosiyanasiyana, kotero kuti sungagwirizane ndi zokutira ndi filimu yophimba. Mwachitsanzo, pamalo pomwe pali UVLED, imbani guluu ndi nayitrogeni, m'malo mwa mamolekyu a okosijeni omwe ali pamwamba pa guluu, ndikuchepetsa kutsekeka kwa okosijeni momwe mungathere. Njira yamankhwala imatha kuwonjezera zotsukira mpweya monga unusamine, sulfurlol, ndi pyrumin mankhwala mu dongosolo. Mankhwalawa amatha kugwiritsidwa ntchito ngati thupi lopatsa mphamvu la haidrojeni kuti ligwirizane ndi peroxide. Kapena gwiritsani ntchito ma polima otsika ndi zosungunulira zokhala ndi mphamvu zochepa za okosijeni, monga ma diluents ogwira ntchito ndi ma polima otsika okhala ndi alpinel, propelinel, ma bond a ether. Opanga zomatira zabwino kwambiri, popanga guluu, amaganizira za vuto la kutsekereza okosijeni, kuti awonjezere ma polima oyenerera ndi zosungunulira zogwira ntchito pagululi. Kaya ukadaulo wochiritsa wa guluu wa ultraviolet ndi wopambana, mbali imodzi, zimatengera gwero la kuwala kwa UVLED, ndipo kumbali ina, zimatengera mawonekedwe a guluu wa ultraviolet. Ziwirizo zikaphatikizidwa, njira yotsika mtengo kwambiri ndiyo kugwiritsa ntchito ndondomeko yopangira mafakitale m'makampani.
