Yimaphi ama-wavelength angcono kakhulu ekwelapheni i-UV LED? Yini odinga ukuyazi

Iyiphi i-Wavelength engcono kakhulu ye-UV LED Curing?

Njengoba izinto eziphulukisiwe zihlukile komunye nomunye, ubude obuhle kakhulu bokuphulukiswa kwe-UV LED nakho kuyashintsha. Yimaphi ama-wavelength angcono kakhulu ekwelapheni i-UV LED? Kodwa-ke, kuphephile ukucabanga ukuthi i-365 nm, i-385 nm, i-395 nm, ne-405 nm izohlanganisa izinhlelo zokusebenza eziningi zezohwebo nezimboni.

• Ama-wavelengths angama-395nm abuse imboni kanye nemikhakha yayo ngenxa yokuba yiyona eguquguqukayo futhi esebenza kahle. Lokhu kungenxa yokuba nama-photoinitiators amahle enza ukwelapha ngokushesha okukhulu ngokungena okuhle kokujula. Lokhu kufanelekile ukuphulukisa ama-inks, ukunamathela okumboza, ngisho ne-fiber optical. Kukhethwa kumasethi amaningi wokukhiqiza ukugcina ibhalansi phakathi kwejubane nokujula.
• Kodwa-ke, ngezinto ezijiyile noma ezinemibala, ukuphulukiswa kokugcwaliswa kwe-365 nm UV LED okwanelisayo kusuka phezulu kuya phansi kusebenza kahle. Ekwelapheni okusheshayo komhlaba, ama-LED we-UV angama-405 nm ahamba kahle futhi alungele izinhlelo zokusebenza ezihamba ngokushesha njengezimonyo kanye ne-elekthronikhi yabathengi.

I-wavelength ngayinye ye-UV inezinzuzo zayo, futhi lokhu kufanele kucatshangelwe. Ububanzi be-wavelength ye- 365nm nm kuya ku-405nm kufanele ifane nohlelo lokusebenza oludingekayo ukufeza izinhloso ezingcono, njengokunciphisa izindleko nokukhulisa ukusebenza.

Inqubo yama-wavelengths kanye nokusebenza kwe-photochemical

Ukuphulukiswa kwe-UV LED kungakhipha ukusabela kwe-photochemical kuma-glues, ukumboza, ngisho nama-inks ngokusetshenziswa kokukhanya kwe-UV, okunamathiselayo, ukumboza, nama-inks. Ama-wavelengths asetshenziswa kakhulu ekuphulukiseni i-UV LED afaka:

• I-365 nm: Ingena ngokujulile ezintweni ezijiyile kangcono.
• I-385nm: Ukuphulukiswa komhlaba nokungena kuyalingana.
• I-395nm: Ukujula okuhle ngokuphulukiswa okusebenzayo.
• I-405nm: Ukwelashwa okusheshayo nokuphulukiswa okusheshayo.

Lawa ma-wavelengths awela ebangeni le-UVA (315-400 nm), elisetshenziswa kabanzi ezinhlelweni zokuphulukisa i-ultraviolet ngenxa yokusebenza kwayo nokuphepha. 

Izici ezithinta ukukhethwa kwe-wavelength

1. Ukuhambisana kwezinto ezibonakalayo

Ama-photoinitiators, izinto zokwakha, kanye nezakhi zazo zokwakha ziphendula kalula kuma-wavelengths athile. Isibonelo, ezinye izinamathiselo nokugqoka zenziwa ukuba ziphulukise ngaphansi kokukhanya kwe-365nm; Kodwa-ke, okunye ukwakheka kungadinga i-395nm noma i-405 nm ukuze isebenze kangcono. 

2. Ukwelapha ukujula nesivinini

Ama-wavelengths amafushane, afana ne-365nm, angena ezintweni ngaphezulu, okwenza kube kuhle ukwelapha izinto ezijiyile noma ezingabonakali. Ngakolunye uhlangothi, ama-wavelengths amade, afana ne-405nm, amuncwa kakhulu ebusweni bokufa. Lokhu kuholela ekuphulukisweni okusheshayo komhlaba. 

3. Ukumuncwa kwe-Photoinitiator

I-photoinitiator ngayinye inesethi ethile ye-spectra yokumuncwa. I-spectrum yokumuncwa kwe-photoinitiator enikeziwe ihlukile kuleyo yomunye i-photoinitiator ngakho-ke idinga ucwaningo olunzulu. Ukufanisa i-UV LED wavelength ku-photoinitiator peak absorption kuzosebenzisa kangcono amandla anikezwayo, ngokuphulukiswa okuhle kohlelo. 

Ukusetshenziswa kwama-wavelengths athile ezinhlelweni ze-UV LED

365nm UV LED Ukwelashwa

Inzuzo yayo eyinhloko yikhono lokungena ngokujulile ezintweni ezijiyile nge-365nm wavelength. Lokhu kwenza kube wusizo lapho uphulukisa izinto ezinemibala noma ezigcwele, lapho kudingeka khona ukungena kwamandla ajulile.

Ngenxa yokujula kwayo kokwelashwa, ukuphulukiswa kwe-365 nm UV LED kuyasiza kakhulu ekugqokeni kwezimboni ngenxa yamandla ayo nokuqina. Kubuye kuthandwa engxenyeni yokuphrinta kwe-3D yama-resins, lapho amandla nokunemba kwezingxenye kuncike ekwelapheni okufanele. Ngaphezu kwalokho, abakhiqizi bamadivayisi wezokwelapha bathemba leli gag lokuphulukisa izinamathiselo ezihambisanayo futhi ezinokwethenjelwa ngenxa yezidingo eziphakeme ze-biocompatibility. 

385 nm UV LED Curing 

Ukuphulukiswa kwe-UV LED ku-385 nm kuyisivumelwano kanye ne-hybrid phakathi kokujula nesivinini. Le wavelength iyahambisana nezinhlobo eziningi zezinto zokwakha njengoba inikeza ukuphulukiswa okusebenzayo komhlaba nangaphansi komhlaba. Ukusetshenziswa kwayo kuvame kakhulu emhlanganweni we-elekthronikhi, lapho ukuphulukiswa kwengxenye nokumboza ngokunemba okuphezulu kubalulekile ekusebenzeni komkhiqizo. Ngaphezu kwalokho, i-385nm ingasetshenziselwa ama-varnishes nokumbozwa njengoba lokhu kudinga ukufana nezindawo ezibushelelezi. Izinto zamazinyo nazo zisebenzisa leli -wavelength njengoba ukwelashwa okusheshayo nokuthembekile kwenziwa ngaphandle kokulimaza izicubu ezibucayi. 

395 nm UV LED Ukwelashwa 

I-395nm wavelength yaziwa ngokuphulukisa okusebenzayo futhi yaziwa kakhulu ngebhalansi yejubane elibushelelezi lokungena. Lokhu kungenziwa ngama-photoinitiators amaningi ajwayelekile, ngakho-ke ingasetshenziselwa izinhlelo zokusebenza eziningi. Le wavelength ivame ukusetshenziselwa ukuphrinta ama-inks, lapho kudingeka khona ukunamathela okusheshayo nokumisa.

Kuyasiza ukunamathela kwengilazi namapulasitiki njengoba kunikeza isibopho esiqinile nesikhathi esincane sokuphulukisa. Ngaphezu kwalokho, i-395nm wavelength isebenza kahle ngokuphulukisa ukumbozwa kwe-fiber optical, okubalulekile ekuxhumaneni ngocingo ngokuphathelene nokucaca nokuqina.

405 nm UV LED Ukwelashwa

I-405nm ye-LED UV ukuphulukiswa kusebenza kahle kakhulu ekwelapheni ebusweni ngenxa yejubane layo. Isetshenziswa kabanzi ebuhleni, njengama-nail gels nezimonyo, inikeza imiphumela ebushelelezi ngesikhathi sokurekhoda ngenxa yokuphulukiswa okusheshayo nokuphulukisa. Imboni ye-elekthronikhi yabathengi nayo iyazuza ekuphulukisweni kwe-405nm kwezingxenye nokugqoka okuvikelayo, okuvumela ukukhiqizwa kwevolumu ephezulu.

Ukwandisa ukusebenza kwe-UV LED Curing

Ukuze uthole imiphumela emihle kakhulu ekuphulukini kwe-UV ye-LED, yenza okulandelayo:

•          I-Mismatch Wavelength ne-Material: Qiniseka ukuthi uhla lwe-UV LED luyanelisa isiphetho se-wavelength se-photoinitiator.

•          Ukushuba Kwezinto Zokwakha: Izinto ezijiyile zidinga ama-wavelengths amafushane ukuze ziphuluke ngokuphelele.

•          I-Taper Irradiance: Setha izinga lokukhanya kwe-UV ukulungisa ijubane lokuphulukisa noma ukugwema ukushisa ngokweqile.

• Lawula Isikhathi Sokuphulukisa: I-Cutlet M1 inkulumo yokuvala isikhathi sokuphulukisa ngaphandle kokuphazamisa kabi ukuziphatha kwezakhiwo zezinto ezibonakalayo.

Isiphetho

Njengoba kuphawuliwe, kubaluleke kakhulu ukukhetha ubude obuhle be-UV wezinqubo zokuphulukisa ze-LED, njengoba kungathinta ukusebenza kahle okuphelele, ukusebenza kahle, kanye nezinga lokukhipha. Vakashela i-UVET Technology ukuthola eminye imininingwane mayelana nobuchwepheshe bokuphulukisa i-UV LED kanye nezinhlelo zokusebenza. Thuthukisa ukutholwa kwesici nokulawulwa kwekhwalithi ngezindlela zokuhlola ze-UV LED eziphephile, eziphumelelayo. Thola namuhla manje!
