Umhlahlandlela we-UV LED Curing Wavelength: 365 nm vs 385 nm vs 395 nm vs 405 nm

Kungani i-Wavelength Matters in UV LED Curing

I-Wavelength ibalulekile ngoba inquma ukuthi amandla okuphulukisa asebenzisana kanjani nezinto zokwakha kanye nama-photoinitiators. Kufanele ufanise ukukhanya kwesibani sakho kuphrofayili yokumuncwa kwamakhemikhali akho ukuqala inqubo ye-polymerization. Uma i-wavelength yakho icishiwe, amandla azodlula ezintweni noma abonise ebusweni ngaphandle kokubangela ukuthi uketshezi lube lukhuni. Ukukhetha kwakho imvamisa nakho kunquma ukuthi ukukhanya kungahamba ngokujula kangakanani ngengubo yakho. Ama-wavelengths amafushane nama-wavelengths amade asebenzisana nama-pigments nama-resin ngezindlela ezahlukene, athinta amandla okugcina okubopha.

Yiziphi izici ze-365 nm UV LED ukuphulukisa?

I-365nm wavelength inikeza ukungena okujulile futhi isebenza kahle ngama-photoinitiators athile azwelayo kulelo banga. Uvame ukusebenzisa le mvamisa lapho udinga ukwelapha ngokusebenzisa izingqimba ezijiyile zokugqoka okucacile noma lapho usebenza ngama-adhesives akhethekile ezimboni. Inikeza amandla aqinile "isibhakela" esikusiza ukuthi uzuze isibopho esiqinile ezingeni le-substrate. Amakhemikhali amaningi wendabuko e-UV ekuqaleni aklanyelwe isiqongo esingu-365 nm esitholakala ezibani ze-mercury. Ukusebenzisa leli -wavelength ekulungiseleleni kwakho kwe-LED kukuvumela ukuthi ugcine ukuhambisana nezinhlobonhlobo zama-resin akhona.

Yiziphi izici ze-385 nm UV LED ukuphulukisa?

I-385nm wavelength ilinganisa ukungena nokwelashwa komhlaba kwezinto ezahlukahlukene. Uzothola ukuthi le mvamisa isebenza njengendawo ephakathi nendawo eguquguqukayo, inikeza ukujula okwanele kwezingqimba ezijiyile ngenkathi isahlinzeka ngamandla anele okuvimbela i-tackiness. Kuyindlela enokwethenjelwa lapho isitolo sakho siphatha izinhlobo eziningana zezingxenye kulayini ofanayo. Uthola uhla olubanzi lokuhambisana naleli -wavelength uma kuqhathaniswa nemvamisa eyeqisayo. Isebenza kahle ngama-photoinitiators amaningi "aphindwe kabili" aphendula ibhande elibanzi kancane lokukhanya kwe-UV.

Yiziphi izici ze-395nm UV LED ukuphulukisa?

I-395nm wavelength isetshenziswa kabanzi kuzicelo zokuphulukisa ezijwayelekile ngenxa yokuqondanisa kwayo okujwayelekile kwe-photoinitiator. Ubona le mvamisa isetshenziswa kaningi ekunyatheliseni kwedijithali, ukuqedwa kwezinkuni, kanye nomhlangano ojwayelekile ngoba ama-inks amaningi anamuhla alungiselelwe ngokukhethekile. Inikeza ukusebenza kahle kwamandla futhi kulula ukuyithola ekulungiseleleni okuningi okujwayelekile kwezibani zezimboni. Uma usebenzisa i-395nm, uthola ithuluzi elijwayelekile elisingatha inqwaba yemisebenzi ejwayelekile yezimboni. Kuhle kakhulu ekwelapheni ngama-inks amnyama noma anemibala eminingi lapho amagagasi amafushane angavinjelwa.

Yiziphi izici ze-405 nm UV LED ukuphulukisa?

I-405nm wavelength inikeza ukwelashwa okusebenzayo komhlaba ngokungena okuncishisiwe uma kuqhathaniswa nama-wavelengths amafushane. Usebenzisa le mvamisa lapho umgomo wakho oyinhloko ukufeza isiphetho esiqinile, esimelana nokuklwebha phezulu komkhiqizo wakho. Imvamisa isetshenziswa ngokuhlanganiswa namanye ama-wavelengths ukuqinisekisa ukuthi ingxenye yomile ukuthinta ngokushesha ngemuva kokushiya ukukhanya. Ngoba lokhu kubude be-wavelength kusondele ku-spectrum yokukhanya okubonakalayo, kungaba kuphephe ezintweni ezithile ezibucayi ezingase ziwohloke ngaphansi kokukhanya okuqinile kwe-UV. Uvame ukuyithola isetshenziselwa ama-resin wokuphrinta we-3D namaglue athile ebangeni lezokwelapha.

Kufanele uqhathanise kanjani ubude be-wavelength kuma-photoinitiators wezinto ezibonakalayo?

Ukuqhathanisa ubude be-wavelength yokuphulukisa kuma-photoinitiators wezinto ezibonakalayo kusekela ukwelashwa okusebenzayo nokuguquguqukayo. Kufanele ngaso sonke isikhathi ubheke ishidi lakho ledatha ukuze uthole "ukumuncwa okuphezulu" kwe-resin yakho noma inki. Umgomo wakho ukukhetha isibani esikhipha ukukhanya ngqo kuleyo nto ukuze uqinisekise ukuthi ukusabela kwamakhemikhali kuqala ngokushesha ngangokunokwenzeka.

• Hlola ishidi ledatha le-inki yakho yebanga elidingekayo le-UV spectral.
• Qinisekisa ukuthi ukukhishwa kwesibani sakho kuhambisana nezidingo zezinto ezibonakalayo.

Lapho ukukhanya kwakho namakhemikhali kufana ngokuphelele, usebenzisa amandla amancane futhi ukhiqiza ukushisa okuncane. Lokhu kuqondanisa kuvimbela amaphutha ajwayelekile okukhiqiza njenge "skinning," lapho kuphela ungqimba oluphezulu luqinile ngenkathi phansi kuhlala kumanzi.

Yiziphi ukuhwebelana okusebenzayo phakathi kwama-wavelengths amafushane namade?

Ukukhetha phakathi kwama-wavelengths amafushane namade kuhilela ukulinganisa ukujula kokwelashwa, isivinini, nokuhambisana kwezinto ezibonakalayo. Ungathola ukuthi ubude obufushane obufana ne-365nm bukunikeza isibopho esijulile kepha kudinga amakhemikhali akhethekile. Ubude obude obufana ne-395nm bungase bube lula ukubuthola kepha kungadinga amandla amaningi ukwelapha ubuso bezinto ezithile zokugqoka. Kufanele futhi ucabangele ukushisa okuzwela kwe-substrates yakho. Ngenkathi wonke ama-LED epholile kunezibani ezindala, ama-wavelengths ahlukene angasebenzisana nezinto zakho ngezindlela ezithinta ukuma kwawo kokugcina.

Yiziphi izinto ezibalulekile ekukhethweni kwe-UV LED wavelength?

Ukukhetha kwakho ubude be-wavelength kuncike kuzidingo ezithile zamakhemikhali zokumboza kwakho nokujula kokwelashwa okudingekayo ezingxenyeni zakho. Kufanele ubeke phambili ukufanisa isibani sakho kuma-photoinitiators akho ukuqinisekisa ukuthi inqubo yakho ihlala izinzile futhi isebenza kahle.

• I-365nm iyisinqumo sakho sokungena okujulile kanye ne-chemistry yefa.
• I-395 nm iyisinqumo esijwayelekile sama-inks amaningi anamuhla nemigqa enejubane eliphezulu.
• I-385 nm ne-405 nm inikeza ibhalansi ekhethekile yokwelashwa komhlaba kanye ne-resin ethile.
• Ukwelashwa okuphumelelayo kudinga ukufana okuphelele phakathi kokukhanya kwakho nempahla yakho.

Uyini umehluko osebenzayo phakathi kwe-365nm ne-395 nm UV LED ukwelashwa?

Uzobona izinguquko ezihlukile endleleni izingxenye zakho zoma ngayo uma uqhathanisa lezi zinto ezimbili.
