Isebenza kanjani ukuphulukiswa kwe-UV LED? Umhlahlandlela we-Photopolymerization
Isebenza kanjani ukuphulukiswa kwe-UV LED? Ukusetshenziswa kwe-UV LED Curing Solutions Uma usebenza ekunyatheliseni, ekukhiqizeni i-3D, noma i-elekthronikhi, ukwazi ukuthi ukuphulukiswa kwe-UV LED kusebenza kanjani kuzoqinisekisa ukuthi usebenzisa kakhulu amathuluzi akho. Izimboni zishintshwa ekusetshenzisweni kwezixazululo zokuphulukisa ze-UV LED ngenxa yokuthi zihlanzekile, zisebenza kahle futhi zishesha kunezindlela zendabuko zokuphulukisa. Le bhulogi ichaza ukuthi ukuphulukiswa kwe-UV LED kusebenza kanjani? Kuyini ukwelapha ngama-LED e-UV? Ukuphulukisa ekukhanyeni kwe-UV ye-LED kubhekisa ekusetshenzisweni kokukhanya kusuka kuma-diode kuya ekuphulukiseni kwe-UV UV nge-UV LED. Lokhu kuhilela ukuqala ukusabela kwamakhemikhali okwenza lukhuni ama-inks noma izinto zokumboza, okusho ukuthi izinamathiselo nazo zidlula ekushintsheni, ziqine. Le ndlela ithandwa kakhulu ngezinzuzo zemvelo ezinikezwayo, kanye nesivinini sayo nokunemba. Isebenza kanjani ukuphulukisa ngama-LED e-UV? Ukusetshenziswa kwama-LED ngaphezu kwalokho kusebenza ukwandisa ububanzi 'bokwelapha ukukhanya' ngoba ama-Light Emitting Diode (LEDs) angasetshenziswa ukukhiqiza ukukhanya kwe-UV. Ukuphulukisa (ukuqina noma ukomisa) kwama-inks, ukumboza, okunamathisela, nama-resin kwenziwa ngokushesha ngokuwaveza ekukhanyeni kwe-ultraviolet kusuka emithonjeni ye-LED D. Ngokungafani nezibani zendabuko ze-mercury, ama-LED e-UV alungiselelwe ukwenza kusebenze ama-photoinitiators ezintweni ezilaphekayo ze-UV. Mechanics of UV LED Curing 1. I-Photopolymerization Inhliziyo ye-i-polymerization yesithombe yenza idivayisi yokuphulukisa ye-UV LED isebenze. Ama-photoinitiators, azwela ukukhanya, ayakwazi ukumunca ukukhanya kwe-UV futhi akhiqize izinhlobo ezisebenzayo kakhulu ezikwazi ukuqala i-polymerization. Ngokwenza kanjalo, ama-monomers awuketshezi nama-oligomers akhona aguqulwa abe ama-polymers aqinile. 2. Indima ...
