Kodi pali kusiyana kotani pakati pa 365 nm ndi 395 nm UV LED

365nm LED ndi chipangizo champhamvu kwambiri chochizira ma ultraviolet chomwe chimagwiritsidwa ntchito kwambiri m'ma diode, kupha tizilombo toyambitsa matenda, komanso kuzindikira kwachilengedwe. Amapha tizirombo ta m'nyumba. Zimathandizanso ndi ndondomeko ya Photosynthesis kuti ithandize kukula kwamphamvu kwa zomera. Gwero la kuwala kwa 365nm limapangidwa ndi gawo lowongolera kutentha, UV LED, dera, gawo lophatikiza, ndi gawo lowunikira. Ndi ya Class-A’kalasi ya ultraviolet wavelength, yomwe imadziwika kuti UV-A.

Mbali inayi, 395nm ma LED ndi ena mwa nyali zabwino kwambiri za UV zopha majeremusi ndi mabakiteriya. Ndiwo kutalika kwa kutalika komwe kumagwiritsidwa ntchito pochiritsa utomoni wa mano. Pali mphamvu zambiri mu mawonekedwe a kuwala. Kuwala kwa backlight uku kumagwiritsidwa ntchito m'mafakitale komanso kupha tizilombo toyambitsa matenda m'zipatala. Zimagwira ntchito yofunika kwambiri, kuyambira kuzindikira mkodzo wa ziweto pansi mpaka kuchotsa madontho a magazi. Utali wa mafundewa umalimba mu gawo la violet ndi lowoneka la ma spectrum.

Komabe, ngati mukufuna yankho lokhazikika lomwe limakwaniritsa zomwe mukuyembekezera, Tianhui ndiye bwenzi loyenera la LED. Ndife a l kuwerenga UV LED Chip wopanga  wopitilira zaka 23.

Ubwino ndi Ntchito za 365 nm ma LED

Mafunde apakati pa 200nm ndi 400nm ndiwo amphamvu kwambiri. 365 nm UV LED  kumawala ngati kuwala kotuwa kotuwa koyera. Yang'anani zolozera zofunika pansipa kuti mudziwe zambiri za ubwino wake ndi ntchito zake.

1  Anti-chinyengo

Kuchokera kumakampani opanga zinthu zapamwamba kupita kumakampani opanga mankhwala, zida zingapo zachitetezo sizidziwika pansi pa kuyatsa kwanthawi zonse. Chotsutsana ndi chinyengo chidzawulula zachitetezo ndikupangitsa kuti ntchitoyo ikhale yogwira mtima komanso yopezeka. Ubwino wake umaphatikizapo:

·  Kuphatikiza kwa Holograms ndi Watermarks : Izi zimawonjezedwa kundalama, zoyikapo, ndi makadi ozindikiritsa kuti apereke chitetezo china. Nthawi zambiri amapangidwa kuti aziyankha ku magetsi a 365nm UV.

·  Kugwiritsa Ntchito Mitundu ya Fluorescent ndi Inks : Inki ndi utoto wa fluorescent zimatsimikizira zowona komanso zowona za zolemba. Izi zimangowoneka zikagwiritsidwa ntchito pansi pa 365nm UV kuwala.

2  Kuchiritsa Adhesive

Kuchiritsa kwa zomatira kumathandizira kubwezeretsa kulimba ndi mtundu wa zinthu zomaliza munjira zamafakitale. Kuwala kwa UV 365nm kumathandizira kuchiritsa zomatira zochokera ku UV makamaka.

·  Amapanga Ma Bond Amphamvu : Zomatira zotetezedwa ndi UV zimapanga zomangira zolimba kuti zipirire zinthu zachilengedwe. Izi zimapangitsa kuti ikhale yabwino pamagalimoto, zamagetsi, ndi zida zamankhwala.

·  Kulondola : The 365nm imatsimikizira kuwongolera kolondola pamachiritso, zomwe zimatsogolera kupamwamba komanso zotsatira zabwino.

·  Kuchita bwino ndi Kuthamanga : Njira yochiritsira ya UV imachitika pa liwiro la mphezi. Zimachepetsa nthawi yopuma ndikuwonjezera ntchito zogulitsa.

3  Kutchera Udzudzu

UV 365nm imathandizira kwambiri kuwongolera matenda ofalitsidwa ndi udzudzu. Ndi njira yopangira misampha popanda kudalira mankhwala owopsa.

·  Kuwonjezeka Mwachangu : Misampha ya UV imachepetsa kuchuluka kwa udzudzu m'deralo powatsekera kudzera pa zomatira kapena zokopera. Zimalepheretsa udzudzu kuthawa.

·  Zothandiza zachilengedwe : Misampha yamakono ya UV iyi siwopseza anthu, ziweto, kapena chilengedwe, chifukwa palibe mankhwala ophera tizilombo.

·  Kukopa : Udzudzu umakopeka ndi misampha iyi ya 365nm UV chifukwa kutalika kwake kumawakokera kumisampha.

  Ubwino ndi Ntchito za 395 nm ma LED

Zofanana ndi 365nm, ndi 395nm UV LED  ilinso mgulu la UV-A. Zikutanthauza kuti kutalika kwa mafundewa ndi kotetezeka komanso kogwira ntchito kuposa njira yochiritsira ya UV komanso mankhwala ophera tizilombo. Tseni’s kulowa mu ntchito zake zosiyanasiyana ndi ubwino.

1  Kuchiritsa kwa Inki

Kuwala kwa UV kumeneku kumawumitsa nthawi yomweyo inki, zomatira, ndi zokutira. Zimathandizira opanga kupanga zosindikiza zolimba komanso zapamwamba. Ubwino wake ndi:

·  Anthu a Nthaŵi : Ma inki ochiritsidwa a UV amapangitsa kuti zinthu zosindikizidwa zikhale ndi moyo wautali. Ma inki amenewa sagonjetsedwa ndi mankhwala, zokanda, ndi kuzimiririka.

·  Kuyanika Mwachangu : Ma inki a 395nm ochiritsidwa ndi UV amawumitsa kwambiri zosindikizira, kuwonjezera mphamvu, ndikuchepetsa nthawi yopanga.

·  Zothandiza zachilengedwe:  Ma inki opangidwa ndi zosungunulira ndi owopsa kuposa ma inki ochiritsidwa ndi UV. Ma inki awa amatulutsa ma VOC otsika kapena Ma Volatile Organic Compounds, kuwapangitsa kukhala otetezeka.

2  Kusindikiza kwa Offset kapena Lithography

·  Kupanga Mwachangu: Inki za 395nm zochiritsa zimauma mwachangu, zomwe zimathandiza opanga kukhala ndi nthawi yosinthira mwachangu.

·  Ubwino Wosindikiza Kwambiri: Inki zotetezedwa ndi UV zimapanga zithunzi zakuthwa, zokhala ndi mitundu yowoneka bwino yomwe imakulitsa kusindikiza.

·  Amagwiritsidwa Ntchito Pazinthu Zosiyanasiyana: Inki yochiritsa ya 395nm LED itha kugwiritsidwa ntchito papulasitiki, mapepala, ndi zitsulo. Imapangitsa kusindikiza kwa offset kukhala kothekera kwa zofalitsa zapamwamba kwambiri komanso kulongedza zinthu.

3  Silk Screen Printing

Kuti apange zojambula zosiyanasiyana zosindikizidwa, opanga amagwiritsa ntchito nsalu yotchinga kapena silika. Inki yochiritsidwa imakankhidwa kudzera pa mesh stencil kuti mupeze zotsatira zapamwamba. Ubwino wake ndi:

·  Superior Quality Adhesion: Ma inki ochiritsidwawa amagwira ntchito bwino pa nsalu, magalasi, zoumba, ndi zitsulo kuti zisindikizo zikhale zokhalitsa.

·  Kuchiritsa Mothamanga Kwambiri: Kuchiritsa mwachangu ndikotheka pogwiritsa ntchito nyali ya 395nm ya LED, yomwe imathandiza osindikiza azithunzi kuti akwaniritse zofuna zapamwamba zopanga.

·  Tsatanetsatane Wovuta Kwambiri: Inki yochizidwa ndi UV iyi imathandiza ndi kusindikiza kodabwitsa, kuwapangitsa kukhala abwino kwapamwamba kwambiri komanso ntchito zabwino.

Kusiyana Pakati pa 365 nm ma LED v/s 395 nm ma LED

Mapeto

Kupita patsogolo ndi zatsopano pagawo la ma LED a UV zapangitsa kuti ntchito zambiri zikhale zotetezeka komanso zogwira mtima. Mafunde a UV-A ndi magetsi ndiwothandiza kwambiri, monga 365nm ndi 395nm. Komabe, zimatengera ogwiritsa ntchito’ zofunika kugwiritsa ntchito iliyonse ya izi. Tapereka wamkati’s mawonekedwe a ma LED onse a UV. Mukhoza kugula izo kuchokera Tianhui kwa magawo osiyanasiyana kapena ntchito
