Indlela yokugwema ukwelashwa kwe-tacky nge-UV LED Spot Curing

Ukwelashwa kwe-tacky kwenzeka lapho ukunamathela okuphulukiswa kwe-UV kuqina ebusweni kepha kuhlala kungalapheki noma kunamathele ngaphansi. Ungabona le nkinga lapho ungqimba oluphezulu lwe-resin yakho luzizwa lomile, kepha isibopho sehluleka ngaphansi kwengcindezi encane yomshini ngoba ungqimba oluyisisekelo luhlala luketshezi.

Le nkinga ivame ukuvela ekuvinjelweni kwe-oksijini ebusweni noma ukwehluleka kwama-photon e-ultraviolet ukungena ekujuleni okugcwele kwesibopho. Ukuqinisekisa ukuthi imihlangano yakho ihlangabezana namazinga ezimboni, kufanele ulungise imingcele yakho yokuphulukisa ukuze ufinyelele ezansi kwesendlalelo sokunamathisela.

Kuyini ukwelashwa kwe-tacky ku-UV LED spot curing?

Ukwelashwa kwe-tacky kwenzeka lapho ukunamathela okuphulukiswa kwe-UV kuqina ebusweni kepha kuhlala kungalapheki noma kunamathele ngaphansi. Uzovame ukubona lokhu lapho i-oksijini emoyeni iphendula ngongqimba oluphezulu lokunamathela, ukuvimbela ama-photoinitiators ukuthi aqede inqubo ye-polymerization. Lokhu kuholela ebusweni obuhlala kancane "emanzi" noma i-gummy ekuthinteni, okungaheha uthuli futhi kuphazamise ubuhle bokugcina bengxenye yakho. Uma ungakuxazululi lokhu, amandla akho esibopho ahlala ephansi kunalokho okuchaziwe, njengoba isakhiwo sangaphakathi sokunamathisela singakafinyeleli ukuminyana okuhlosiwe okuxhunyiwe.

Kungani ukwelashwa kwe-tacky kwenzeka ngokuphulukiswa kwendawo?

Ukwelashwa kwe-tacky kwenzeka ngoba amandla e-UV alethwe ayenganele ngamandla noma isikhathi ukuqala ngokugcwele i-polymerization kuyo yonke inamathiselo. Ungase ubhekane nalokhu uma usebenzisa isibani esingakhiqizi ukukhanya okwanele ukunqoba ukumelana kwamakhemikhali kwe-resin. Lapho ukukhanya kubuthakathaka kakhulu, ama-photon amuncwa ngama-microns ambalwa aphezulu wezinto ezibonakalayo, engashiyi lutho ezingxenyeni ezijulile. Ukubekwa kabi kwe-wand yendawo noma ukubamba ukukhanya nge-angle eyeqile nakho kungadala izindawo "ezinomthunzi" lapho ukunamathela kungatholi khona amandla, okuholela emaphaketheni ewuketshezi.

How does wavelength affect the risk of tacky cure?

I-Wavelength ithinta ukwelashwa kwe-tacky ngoba ama-photoinitiators kuma-adhesives aphendula ngokuqinile kuma-wavelengths athile e-UV futhi ukungalingani kunciphisa ukusebenza kahle kokwelashwa. Kufanele uqinisekise ukuthi ukukhishwa okuphezulu kwesibani sakho se-LED kufana nephrofayili yokumuncwa kokunamathela kwakho, imvamisa ku-365nm, 385nm, noma 395nm. Uma usebenzisa isibani esingu-405nm ku-adhesive eyenzelwe i-365nm, ukusabela kwamakhemikhali kuzoba buthakathaka. Lokhu kungalingani kwe-spectral kuvame ukuholela ekwelapheni okungaphezulu kuphela lapho phezulu kubukeka komile kepha ukuntuleka kokumuncwa kwamandla kuvimbela isisekelo ukuthi sibe lukhuni kahle.

How do Exposure Time and Intensity Influence Tacky Cure?

Kokubili isikhathi sokuvezwa nokuqina kwe-UV kunomthelela engozini yokwelashwa kwe-tacky ngoba umthamo owanele kufanele ufinyelele ekubambeleni ukuze uyiguqule ngokugcwele kusuka kuketshezi kuya ekuqinile. Ungacabanga ngamandla "njengamandla" ngemuva kwama-photon nesikhathi njenge "ivolumu" yamandla alethwayo. Uma ukuqina kwakho kuphansi kakhulu, ama-photon awakwazi ukucindezela ungqimba olungaphezulu ukuphulukisa isisekelo. Ngakolunye uhlangothi, ngisho nokuqina okuphezulu, uma isikhathi sakho sokuvezwa sifushane kakhulu, ukusabela kwamakhemikhali kuzoma ngaphambi kokuqedwa. Ukuthola ibhalansi efanele kuqinisekisa ukuthi ingxenye ngayinye yesibopho ithola ama-Joules adingekayo ngesentimitha lesikwele.
