Kodwa-ke, ngesivinini esiphezulu (isb., Ngaphezu kuka-500 fpm), lelo windi lokuchayeka liyancipha libe ngama-milliseconds. Isitha esiyinhloko lapha ukuvimbela umoya-mpilo. I-oksijini ...

Ngikhumbula okokuqala ngqa lapho ngihamba phansi ukukhiqiza ngishintsha kusuka kumalambu wendabuko e-mercury arc kuya ezinhlelweni zokuphulukisa ze-uv eziholela zokumboza. Umehluko wawushesha—hhayi nje ekuthuleni kwabalandeli, kodwa ukwehla okungazelelwe kokushisa okuzungezile. Kubaphathi bokukhiqiza, ukushintshela ku-UV LED akugcini nje "ngokuya oluhlaza"; imayelana nokulawula ngokunemba. Kepha uma usuthathe isinqumo sokuthuthukisa, isithiyo esilandelayo sihlelekile: Ingabe udinga uhlelo lwe-static Area Curing noma uhlelo lwe-Conveyor olunamandla? Lesi sinqumo sinquma i-throughput yakho, isikhala sakho saphansi, futhi ekugcineni, ikhwalithi yokuqeda kwakho. Kulo mhlahlandlela, siphula imishini, amacala okusebenzisa, kanye ne-ROI yazo zombili izicucu ukukusiza ukuthi uthuthukise umugqa ophelele. Yiziphi izinhlelo zokuphulukisa ze-UV LED zokumboza? Izinhlelo zokuphulukisa ze-UV LED zokumboza zisebenzisa ama-diode akhipha ukukhanya okuphezulu ukwenza i-polymerize (lukhuni) ukumbozwa kwamanzi ngaphandle kokushisa noma isikhathi sokushisa esihambisana nezibani ze-mercury. Lezi zinhlelo zombuso oqinile zinikeza ukulawula okuqondile phezu kwe-irradiance kanye nobude be-wavelength (imvamisa i-365nm, 385nm, i-395nm, noma i-405nm), ibenza balungele ama-substrates azwela ukushisa kanye nemigqa yokukhiqiza enejubane eliphezulu. Ukushintshwa kusuka ku-Thermal kuya ku-Photopolymerization Ngokungafani nama-oveni omiswe ashisayo akhipha ama-solvents ngaphezulu kwemizuzu noma amahora, ukuphulukiswa kwe-UV LED kuyinqubo ye-photopolymerization. Kwenzeka nge-milliseconds. Lapho ubude obuthile bokukhanya kwe-UV bushaya ama-photoinitiators ekugqokeni kwakho, kubangela ukusabela kochungechunge okuxhumanisa ama-oligomers nama-monomers ngokushesha. Kuwe, lokhu kusho: Ukuhlola izisekelo zalobu buchwepheshe, hlola ukujula kwethu okujulile ku UV LED Curing for Coatings. ...
