Kufunika kwa UV LED 405nm mu Kusindikiza kwa 3D

Kodi mukudziwa kuti msika wapadziko lonse wa UV LED Printers ukuyembekezeka kugunda ndalama $ 925 miliyoni  pofika kumapeto kwa 2033? Ma LED a UV asanduka ukadaulo wokongola wopangira kuwala kwambiri komanso kugwiritsa ntchito mphamvu pang'ono kwinaku akusangalala ndi moyo wautali komanso kutulutsa kutentha pang'ono.

Ndi kupita patsogolo kwanthawi zonse pakusindikiza kwa digito, mayankho amakono opangidwa ndi UV ayamba m'malo mwa nyali zachikhalidwe, zanjala yamphamvu ya mercury (Hg). Kuthamanga kwabwino komanso kugwiritsa ntchito mphamvu zochepa Ma board a UV LED amakhala ndi moyo wautali komanso zovuta zochepa pakutaya.

Pokumbukira izi, ma LED a UV okhala ndi kutalika kwa 405nm ndi opindulitsa kwambiri pakusindikiza kwa 3D. Komanso, ndizothandiza komanso zowononga zachilengedwe m'malo mwa nyali za mercury. Pitilizani kuwerenga kuti muwulule gawo lofunikira la 405nm UV kuwala mu njira zosindikizira za 3D.

Kumvetsetsa UV Spectrum ndi Komwe 405nm Ikwanira

A  UV LED 405nm imatulutsa kuwala kwa ultraviolet ndi utali wosankhidwa kale. Monga tonse tikudziwa, mawonekedwe a UV amachokera ku 100nm mpaka 400nm kutengera kutalika kwake, komwe kumayesedwa mu nm. 

Nthaŵi UV LED 405nm kutalika kwa mafunde kumakwanira pamwamba pa mawonekedwe a UV ndipo nthawi zambiri amatchedwa “UV-A Kuwala” Ma LED a UV okhala ndi kutalika kwake kwamtunduwu amagwiritsidwa ntchito m'mafakitale osiyanasiyana, monga zamagetsi, kusindikiza kwa inkjet ya digito, kusindikiza kwa 3D, kupanga zida zamankhwala, njira zochizira, kutsatsa kwachitetezo, ndikupha tizilombo toyambitsa matenda. 

Ngakhale kuyatsa kwachindunji komanso kwanthawi yayitali ku nyali za UV kumatha kukhala kovulaza maselo amunthu, UV-A nthawi zambiri imawonedwa ngati yocheperako kuposa kuwala kwa UV komwe kumakhala ndi mafunde afupiafupi (ie, kuyambira 100nm mpaka 280nm).

Makhalidwe Apadera a 405nm UV Kuwala 

Kutalika kwa 405nm UV kuwala kumakhala m'chigawo cha violet cha ma electromagnetic spectrum. Lili ndi makhalidwe apadera awa:

l  Kutalika kwa mafundewa kumakhala ndi mphamvu zambiri pa photon, zomwe zingagwiritsidwe ntchito muzochita zosiyanasiyana zamafakitale.

l  Kuwala kwa 405nm UV kumatha kusangalatsa ma fluorophores chifukwa chautali wake wamfupi kuposa kuwala kowoneka.

l  Chifukwa chakulowa kwake kochepa, kuwala kwa 405nm UV kumatha kulumikizana mosavuta ndi zida zapamwamba 

Momwe UV LED 405nm Imagwirira Ntchito Kusindikiza kwa 3D?

Pakusindikiza kwa 3D, gawo lililonse liyenera kukhazikika ndikuchiritsidwa litangotulutsidwa. UV  Njira zochiritsira za LED zili ndi luso lapamwamba ndipo zitha kugwiritsidwa ntchito bwino pakusindikiza kwa 3D kwa mbali zamagalimoto, nsapato, zodzikongoletsera, ndi ma prototypes.  

Ma LED a 405nm a UV amagwira ntchito podutsa ma electron kuchokera ku diode semiconductor, kutulutsa mphamvu ngati ma photon a UV. Kuchiritsa kwa njira zina zosindikizira, monga stereolithography (SLA), kugwiritsa ntchito ukadaulo wa UV kumatha kukhala kotopetsa chifukwa zimatengera ma photoinitiators.

Photoinitiators ndi zinthu zomwe zimakhudzidwa ndi mafunde enaake, monga 405nm yoyendetsedwa . Amagwiritsidwa ntchito pakusweka kwa mgwirizano ndikupanga maubwenzi atsopano pakati pa oligomers.

Pamene zomangira zatsopano zimapanga, zimachiritsa bwino zomatira mu mawonekedwe omwe akufuna. Mwanjira iyi, ukadaulo wa UV LED ungagwiritsidwe ntchito kuchiritsa magawo popanda kuwononga dongosolo, chilengedwe, ndi maselo amunthu. 

Kutalika kosankhidwa kwa ma board amphamvu kwambiri a UV LED kumapangitsa kuti azitha kuyambitsa zomatira. NDIPO njira iyi imabweretsa njira yochizira bwino komanso yofulumira, zomwe zimathandizira kuchepetsa nthawi yokonza ndikuwonjezeka kwachangu.

Kumvetsetsa Udindo wa 405nm UV LED mu Njira Yosindikizira ya 3D

Njira zosindikizira zotsatirazi zimagwiritsidwa ntchito pamakampani osindikizira a 3D:

1. Stereolithography (SLA)

2. Fused Deposition Modeling (FDM)

3. Carbon CLIP Technology 

4. Selective Laser Sintering (SLS)

UV LED 405nm imagwirizana ndi mawonekedwe a violet, abwino kuchiritsa ma resin a photopolymer, omwe amagwiritsidwa ntchito makamaka mu Digital Light Processing (DLP) ndi Stereolithography (SLA).

Pakusindikiza kwa utomoni wa 3D, kuwala kwa 405nm UV kumagwira ntchito yofunika kwambiri poyambitsa njira ya photopolymerization, yomwe imayambitsa kulimbitsa utomoni wamadzimadzi muzinthu zomwe mukufuna. Njira yosindikizira ya 3D imaphatikizapo kupanga zigawo zamagulu omwe mukufuna, monga chitsulo, polima, kapena utomoni, mpaka ataphatikizana ndi mawonekedwe omwe mukufuna.

Popeza zingakhale zovuta kugwiritsa ntchito zida zopangira mosalekeza ngati malo ogwirira ntchito sanaume nthawi yomweyo. Chifukwa chake, ma composites amatha kuumitsidwa akamawumitsa poyatsa ndi kuwala kwa 405nm UV, kulola kuti zida zambiri zizigwiritsidwa ntchito powonjezera masanjidwe. 

Kuphatikiza pa kuchiritsa kwa utomoni pakusindikiza kwa 3D, 405nm LED itha kugwiritsidwanso ntchito pokonza zinthu zomwe zidapangidwa. M'makampani osindikizira a 3D, njirayi ikuchitika kuti ipititse patsogolo makina ndi machitidwe azinthu. Komanso, kuwala kwa UV kumathandizira kukulitsa kukana komanso kuchepetsa kuchepa 

Zifukwa ndi Ubwino Wogwiritsa Ntchito Ma LED a UV Pakusindikiza kwa 3D

1. Kusunga Mtengo ndi Kugwiritsa Ntchito Mphamvu Mwachangu 

Chimodzi mwazinthu zodziwika bwino zaukadaulo wa UV LED 405nm ndi mphamvu yake yodabwitsa komanso kupulumutsa mtengo. Mosiyana ndi machitidwe ochiritsira ochiritsira, magwero a UV LED amathandizira’t amawononga mphamvu zambiri. Njirayi pamapeto pake imabweretsa kuchepa kwa chilengedwe komanso kuchepa kwa ndalama zamagetsi.

2. Kusintha Kwachangu Kwambiri 

Ubwino wina woyamikirika wa 405nm LED ukadaulo ndikuti ukhoza kusinthidwa ON / OFF mwachangu popanda kuwononga makina anu. Nyali zachikale za mercury zimagwira ntchito ngati arc yozungulira. Komanso, ali ndi gawo lochepa la kutulutsa kosiyanasiyana. Chifukwa chake, amapitiliza kutulutsa kutentha ndikugwiritsa ntchito mphamvu kaya inu’kusindikizanso kapena ayi.

Mosiyana ndi izi, ma LED a UV osindikizira a 3D amatha kusinthidwa mwachangu kuti asinthe kuwala. Popeza bolodi la UV LED 405nm limangoyatsidwa pakafunika, moyo wake ukhoza kupitilira zaka.

3. Moyo Wautali ndi Kukhalitsa 

Kodi mukudziwa moyo wautumiki wa chip chimodzi chokhala ndi ukadaulo wa UV LED ndi pafupifupi maola 10,000 mpaka 15,000, kutengera kutentha kwa kutentha? Izi zikutanthauza kuti ngati bolodi la UV LED 365nm likuyenda maola 8 patsiku, ndi moyo wautumiki wa maola 10,000, limatha zaka 5. Zikuwoneka zochititsa chidwi?

Popeza ma board a UV LED amakhala WOZIMA mumayendedwe osasindikiza, moyo wawo weniweni wautumiki ukhoza kukulitsidwanso. Njira zochiritsira zachikhalidwe monga nyali za high-pressure mercury (Hg) zimapanga mpweya wa ozone, womwe umayenera kuchotsedwa ndi mpweya wabwino ndipo ukhoza kuchititsa kuti makina anu aziwonongeka nthawi zonse. 

Mosiyana ndi izi, ukadaulo wa UV LED umadziwika bwino chifukwa chodalirika komanso kulimba kwake. Gulu lapamwamba la UV limapangitsa kuti nthawi yocheperako ikhale yocheperako, kusindikiza kosasintha, komanso kutsika mtengo kokonza 

4. Kuthamanga Kwambiri Kupanga

Aliyense akufuna kusunga nthawi m'dziko losindikizira la digito, ndipo UV LED 405nm imapereka mwayi waukulu pankhaniyi. Kusintha kwachangu kwambiri komanso kuchiritsa pompopompo kwaukadaulo kumatha kuthetsa kufunika kowumitsa nthawi ndikufulumizitsa kupanga. 

Komanso, mphamvu yochiritsa mwachangu yaukadaulo wa UV imafulumizitsa mayankho osindikizira makonda ndikuthandizira mabizinesi kuti akwaniritse nthawi yayitali. Koposa zonse, kusinthika kwachangu kwa UV LED 405nm kumatha kukhala kosintha pamasewera osindikizira a 3D, kukupatsirani mwayi wopikisana nawo omwe akupikisana nawo. 

5. Wavelength Yeniyeni 

The wavelength osankhidwa mosamala wa  UV LED 405nm sichimangokhala. M'malo mwake, imagwirizana ndi mawonekedwe a mayamwidwe omwe amagwiritsidwa ntchito kwambiri pa zomatira za UV.

Kusankha kolingalira bwino kwa kutalika kwa mafunde kumatsimikizira kuti kuwala kwa Ultraviolet kumayamwa mokwanira ndikuyambitsa njira yabwino yochiritsira guluu popanda kutentha kwambiri. Komanso, zimabweretsa kuchiritsa koyendetsedwa bwino komanso kolondola popanda kuwononga magawo okhudzidwa 

Pansi Pansi

Kotero, izo zikuphatikiza lero lathu’Ndemanga ya UV LED 450nm. Ma diode otulutsa kuwala okhala ndi mawonekedwe a UV awa amawonetsa kuthekera kodalirika pantchito yosindikiza ya 3D.

NDIPO zikafika popeza opanga ma LED oyenera a UV, mukudziwa yemwe mungalumikizane naye - Zhuhai Tianhui Electronic . Pokhala ndi zaka zopitilira 20 muntchito za OEM/ODM, timatha kupereka ma LED apamwamba kwambiri a UV pazifukwa zingapo pamitengo yotsika mtengo.

Lumikizanani nafe lero kuti mudziwe zambiri zamayankho athu apamwamba a UV LED pazogwiritsa ntchito zingapo!
