I-395 nm UV LED Yokuphulukisa Isibani: Ukusetshenziswa Okujwayelekile Namathiphu Wokukhetha

Kuyini isibani sokuphulukisa se-395 nm UV LED?

Isibani sokuphulukisa se-UV LED esingu-395 nm ngumthombo wokukhanya we-UV we-UV okhipha amandla aseduze-UV agxile ku-395 nm evame ukusetshenziselwa izinto eziphendula kulowo mkhawulokudonsa. Uzobona ukuthi le wavelength ihlala ekugcineni okuphezulu kwe-UVA spectrum, inikeza i-photon yamandla aphansi uma kuqhathaniswa namagagasi amafushane e-UV kodwa ngezinga eliphakeme lokuzinza.

Lobu buchwepheshe bombuso obuqinile buthatha indawo yama-bulbs wendabuko e-mercury, bukunikeza amandla okusheshayo kanye nesikhathi sokuphila eside sokusebenza. Ngenxa yokuthi iyi-emitter emincane, amandla agxile ngokukhethekile lapho ama-photoinitiators amaningi anamuhla aklanyelwe ukusabela.

Yiziphi izinto kanye nama-photoinitiators asebenza kahle ngezibani zokuphulukisa ezingama-395nm?

Izibani zokuphulukisa ezingama-395 nm zilungele kahle izinto ezine-photoinitiators ezimunca kahle eduze kwaleli -wavelength, ikakhulukazi lezo ezisemndenini we-Acylphosphine oxide. Kufanele ubheke ama-resin aqukethe ama-initiators afana ne-TPO noma i-BAPO, aklanyelwe ukubamba amandla ebangeni le-380 nm kuya ku-400 nm.

Lezi zinto zisebenza kahle kakhulu ekuguquleni ama-photon angama-395 nm abe izinhlobo ezisebenzayo ezidingekayo ukuqinisa ukumbozwa kwakho. Lokhu kuqondanisa kwe-spectral kuqinisekisa ukuthi amandla asetshenziswa ngempumelelo, ukunciphisa amandla aphelele adingekayo ukufinyelela ekwelapheni okuphelele.

Yiziphi izinhlelo zokusebenza ezijwayelekile ezisebenzisa izibani zokuphulukisa ze-395 nm UV LED?

Izibani zokuphulukisa ze-395nm ze-UV LED zivame ukusetshenziswa ezinhlelweni ezifana nezinamathiselo, ama-inks, ukumboza, namafilimu amancane lapho ukusebenza okuseduze-UV kusebenza khona. Uzozithola zamukelwa kabanzi ekunyatheliseni kwe-inkjet yedijithali nokukhiqizwa kwamalebula ngoba ubude be-wavelength bungena ngokujulile ngama-pigment aminyene afana ne-carbon black noma i-titanium dioxide.

Emkhakheni we-elekthronikhi, usebenzisa lezi zibani ukubopha izixhumi kanye nezingxenye ezibucayi lapho ukwelashwa okupholile, okungaguquguquki kuyadingeka ukuvikela i-substrate. Zijwayelekile futhi emhlanganweni wedivayisi yezokwelapha zokujoyina izingxenye zepulasitiki, njengoba i-395nm wavelength inikeza isibopho esiqinile ngaphandle kokubangela ubuthakathaka noma ukuphuzi kwesinye isikhathi kuhlotshaniswa nama-UV amafushane amafushane.

How does 395 nm UV LED curing compare to adjacent wavelengths?

Uma kuqhathaniswa nama-wavelengths amafushane noma amade e-UV LED, i-395nm inikeza ibhalansi yokusebenza komhlaba nokungena okulinganiselayo kwama-photoinitiators amaningi ajwayelekile nezinto zokwakha. Ngenkathi umthombo we-365 nm uhlinzeka ngamandla aphakeme wobulukhuni obukhulu bendawo, uvame ukulwa ukungena ngezimbobo ezijiyile noma ezimnyama.

Ngakolunye uhlangothi, i-405nm "imnene" futhi isondele ekukhanyeni okubonakalayo, okungase kuphephe ezintweni ezibucayi kakhulu kepha kungahamba kancane ukwelapha. Isiqongo esingu-395 nm siyisinqumo "esivamile" ngoba sinikeza ukujula okwanele kokumbozwa kwezimboni ngenkathi kugcinwa isikhathi esisheshayo somile.

Yiziphi izici okufanele uzicabangele lapho ukhetha isibani se-UV LED esingu-395 nm?

Ukukhetha isibani sokuphulukisa se-UV LED esingu-395 nm kuhilela ukulinganisa izinto ezifana namandla okukhipha, usayizi wendawo, izici zezinto ezibonakalayo, kanye nesivinini sokukhiqiza. Kufanele uqinisekise ukuthi ukukhanya (kulinganiswa ngo-$W / cm ^ 2 $) kuphakeme ngokwanele ukudala ukusabela kwamakhemikhali ngesivinini sakho esithile sokuhambisa. Ngaphezu kwalokho, usayizi wekhanda lesibani kufanele uhambisane nendawo yakho yokuphulukisa ukuqinisekisa ukuthi ingxenye ngayinye yomkhiqizo wakho ithola umthamo ofanayo wokukhanya.

• Ukuminyana Kwamandla: Qinisekisa ukuthi ukukhanya okuphezulu kuhlangabezana nezidingo ezincane ezishiwo ephepheni lakho ledatha yezinto ezibonakalayo.
• Indlela yokupholisa: Khetha phakathi kwamayunithi apholile emoyeni noma apholile amanzi ngokuya ngesikhala sesikhungo sakho nezidingo zokushabalalisa ukushisa.
• Ibanga lokusebenza: Cabanga ukuthi isibani sizoba kude kangakanani nomkhiqizo, njengoba ukuqina kwehla kakhulu njengoba ibanga likhuphuka.
• Ukufana: Bheka ama-optics ahlinzeka ngokusatshalaliswa okukhanyayo ukugwema "izindawo ezithambile" ekugcineni kwakho.

Yikuphi ukuhweba okusebenzayo okukhona nge-395 nm UV LED ukuphulukisa?

Ukuhweba okusebenzayo ngokuphulukiswa kwe-395nm kufaka phakathi ukulinganisa ukusebenza kokwelashwa komhlaba ngokumelene nokungena okujulile nokuphendula kwe-initiator. Ungathola ukuthi ngenkathi ukukhanya kufinyelela ezansi kwesendlalelo sokunamathela esiqinile kahle, indawo ephezulu kakhulu ingahlala i-tacky kwezinye ukwakheka ngenxa yokuvinjelwa kwe-oksijini.

Ukuze unqobe lokhu, kungase kudingeke ukwandisa ukuqina kwesibani noma usebenzise uhlelo lwe-dual-wavelength. Ngaphezu kwalokho, ngoba kuwumthombo webhendi elincane, ulahlekelwa "ukuguquguquka" kwezibani ze-mercury ezibanzi, okusho ukuthi i-chemistry yakho yezinto ezibonakalayo kufanele ihambisane ngokunembile nalesi siqongo se-395nm.

Kufanele uqinisekise kanjani isixazululo sokuphulukisa se-395nm UV LED?

Ukuqinisekiswa kwesisombululo sokuphulukisa esingu-395 nm kudinga ukuhlolwa okulawulwayo kokwelashwa kwezinto ezibonakalayo, ukuqapha ukusebenza kwemishini, nokulungisa ukuguquguquka kwenqubo. Kufanele uqale ngokugijima amasampula esiteshini sokuhlola ukukala ubulukhuni bokugcina nokunamathela kokumboza. Sebenzisa i-radiometer ukulandelela amandla angempela e-UV alethwe engxenyeni, ngoba lokhu kukuvumela ukuthi udale "iwindi lenqubo" eliphindaphindiwe.

1. Yenza isivivinyo se-Cross-Hatch: Qinisekisa amandla esibopho phakathi kwengubo ne-substrate.
2. Yenza isivivinyo se-solvent rub: Hlola ukumelana kwamakhemikhali ebusweni ukuze uqinisekise ukwelashwa okuphelele.
3. Linganisa umthamo wamandla: Bhala ama-Joules ngesentimitha ngalinye lesikwele ($J / cm ^ 2 $) edingekayo ngesivinini sakho somugqa ohlosiwe.
4. Hlola umthelela wokushisa: qapha izinga lokushisa lengxenye ukuqinisekisa ukuthi lihlala ngaphakathi kwemingcele ephephile ye-substrate yakho.

Yiziphi izinto ezibalulekile ezithathwayo ekusebenziseni izibani zokuphulukisa ze-395nm UV LED?
