Deep UV imatha kuletsa coronavirus

 Ultraviolet disinfection ndi njira yakale komanso yodziwika bwino. Zowumitsa padzuwa ndizomwe zimagwiritsidwa ntchito kale kwambiri ndi cheza cha ultraviolet kuchotsa nthata, kupha tizilombo, ndi kutseketsa.

 Poyerekeza ndi kutseketsa kwa mankhwala, UV ili ndi mwayi wotseketsa bwino kwambiri, kuyimitsa nthawi zambiri kumamaliza pakangopita masekondi angapo, ndipo sikutulutsa zinthu zina zowononga mankhwala. Chifukwa ndi yosavuta kugwiritsa ntchito ndipo imatha kuyikidwa m'malo onse, nyali zowononga majeremusi za UV zakhala chinthu chodziwika bwino pamapulatifomu akuluakulu a e-commerce. M'mabungwe azachipatala ndi azachipatala oyamba, ndikofunikiranso zida zotsekera.

Deep UV LED, makampani omwe akuwonekeratu

Kuti mukwaniritse njira yotseketsa komanso kupha tizilombo toyambitsa matenda ndi cheza cha ultraviolet, zofunika zina ziyenera kukwaniritsidwa. Samalani kutalika kwa mafunde, mlingo, ndi nthawi ya gwero la kuwala kwa ultraviolet. Ndiko kuti, kuyenera kukhala kuwala kwakuya kwa ultraviolet mu gulu la UVC ndi kutalika kwa kutalika kwa 280nm ndipo iyenera kukumana ndi mlingo wina ndi nthawi ya mabakiteriya osiyanasiyana ndi mavairasi, mwinamwake, sizingatheke.

Malinga ndi gawo la kutalika kwa mawonekedwe, gulu la ultraviolet limatha kugawidwa m'magulu osiyanasiyana a UVA, UVB, UVC. UVC ndiye gulu lomwe lili ndi utali wamfupi kwambiri komanso wamphamvu kwambiri. M'malo mwake, pochotsa ndi kupha tizilombo toyambitsa matenda, yothandiza kwambiri ndi UVC, yomwe imatchedwa band yakuya ya ultraviolet.

Kugwiritsa ntchito nyali zakuya za ultraviolet m'malo mwa nyali zachikhalidwe za mercury, kugwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda, ndi kutseketsa ndikufanana ndi kugwiritsa ntchito ma LED oyera kuti alowe m'malo mwa nyali zachikhalidwe m'malo owunikira, zomwe zipanga makampani akulu akutuluka. Ngati kuwala kwakuya kwa ultraviolet LED kumazindikira kulowetsedwa kwa nyali ya mercury, zikutanthauza kuti m'zaka khumi zikubwerazi, mafakitale akuya a ultraviolet adzakhala makampani atsopano a thililiyoni monga kuwala kwa LED.

Ma LED akuya a UV amagwiritsidwa ntchito kwambiri m'magawo aboma monga kuyeretsa madzi, kuyeretsa mpweya, komanso kuzindikira kwachilengedwe. Kuphatikiza apo, kugwiritsa ntchito gwero la kuwala kwa ultraviolet ndikochuluka kwambiri kuposa kuthirira komanso kupha tizilombo. Ilinso ndi chiyembekezo chokulirapo m'magawo ambiri omwe akubwera monga kuzindikira kwa biochemical, chithandizo chamankhwala choletsa kubereka, kuchiritsa kwa polima, ndi photocatalysis ya mafakitale.

Ukadaulo waukadaulo wakuya wa UV LED ukadali m'njira

Ngakhale ziyembekezo ndi zowala, sizingatsutse kuti ma LED a DUV akadali koyambirira, ndipo mphamvu ya kuwala, kuwala kowoneka bwino, komanso moyo wautali sizili zokhutiritsa, ndipo zinthu monga UVC-LED ziyenera kukonzedwa bwino ndi kukhwima.

Ngakhale kutukuka kwa ma LED akuya a ultraviolet kumakumana ndi zovuta zosiyanasiyana, ukadaulo wapita patsogolo.

Mwezi watha wa Meyi, mzere woyamba padziko lonse lapansi wopanga zinthu zambiri wokhala ndi tchipisi ta 30 miliyoni zamphamvu kwambiri za ultraviolet LED zidapangidwa ku Luan, Zhongke, pozindikira kukula kwakukulu kwaukadaulo waukadaulo wa chip cha LED ndikuyika zida zapakati.

Ndi kupita patsogolo kwa ukadaulo, kusiyanasiyana, komanso kuphatikiza kwa mapulogalamu, magawo atsopano ogwiritsira ntchito akupitilizidwa nthawi zonse, ndipo miyezo ikufunika kuwongolera nthawi zonse. "Miyezo ya UV yomwe ilipo kale imachokera ku nyali zachikhalidwe za mercury. Pakalipano, magetsi a UV LED amafunikira mwamsanga miyeso yambiri kuyambira pakuyesa mpaka kugwiritsa ntchito.

Pankhani ya kuyatsa kwakuya kwa ultraviolet ndi kupha tizilombo toyambitsa matenda, kuyimitsidwa kumakumana ndi zovuta zingapo. Mwachitsanzo, kutsekereza nyali ya ultraviolet mercury kumakhala kwambiri pa 253.7nm, pomwe mawonekedwe a UVC LED amagawidwa makamaka pa 260-280nm, zomwe zimabweretsa kusiyanasiyana kwamayankho azotsatira.

Mliri watsopano wa chibayo wapangitsa kuti anthu amve zambiri pazakudya ndi kupha tizilombo toyambitsa matenda a ultraviolet, ndipo mosakayikira alimbikitsa chitukuko cha mafakitale a ultraviolet LED. Pakalipano, anthu omwe ali m'makampaniwa amakhulupirira izi ndipo amakhulupirira kuti makampaniwa akukumana ndi mwayi wopita patsogolo. M'tsogolomu, chitukuko cha mafakitale akuya a ultraviolet LED chidzafuna mgwirizano ndi mgwirizano wa maphwando akumtunda ndi kumtunda kuti "keke" iyi ikhale yaikulu.
