Kuwe, lokhu kusho: Ukuhlola izisekelo zalobu buchwepheshe, hlola ukujula kwethu okujulile ku UV LED Curing for Coatings. ...

Ezinqubweni zanamuhla zokukhiqiza eziphezulu nezimboni, ukuhlolwa kwe-UV fluorescence sekuyindlela ebalulekile esetshenziselwa ukukhomba ukukhubazeka, imifantu nokungcola ebusweni.  Le ndlela isebenzisa isici sokukhanya kwe-ultraviolet sokuba nekhono lokuveza ukukhubazeka okungabonakali ukukhiqiza isithombe esiphezulu se-UV sokukhethwa okubanzi kwezinto zokwakha, njengezinsimbi, ama-polymers, ukumboza, nezinamathiselo. Izimboni ziyakwazi ukunquma ikhwalithi, ukuhambisana, nokuphepha ngokusebenzisa izinhlelo zokuhlola ze-ultraviolet fluorescence ukuthuthukisa ukusebenza kahle. Lezi zinhlelo zibandakanya ukusetshenziswa kokuhlolwa kokukhanya kwe-UV, ukuhlolwa kodayi we-fluorescent, kanye nokuhlolwa kwe-UV okungabhubhisi (NDT) ukuze kunikeze imiphumela engaguquguquki, enokwethenjelwa. The Insight into UV Fluorescence Inspection Ukuhlolwa kwe-UV fluorescence kuyindlela yokuhlola engabhubhisi (i-NDT), esebenzisa ukusetshenziswa kokukhanya kwe-ultraviolet (UV) ukukhiqiza i-fluorescence ngodayi, ukumboza, okunamathisela, noma ezinye izinto. Ukungapheleli noma ukungcola kwe-fluoresce lapho ukukhanya kwe-UV kuphonswa ebusweni, futhi kungatholwa ngabahloli. Izinzuzo eziyinhloko zale ndlela yilezi: Le nqubo ithola ukusetshenziswa okukhulu ekuhlolweni kodayi we-UV fluorescent, ukuhlolwa kwe-UV penetrant, kanye nezinhlelo zokuthola ukukhubazeka kwe-UV. Ngokuhlanganisa ukuhlolwa okunembile komthombo wokukhanya kwe-UV kanye nokuhlolwa kwe-fluorescence ebusweni, izimboni zingabona ukukhubazeka okungabonakali ngaphansi kwezimo ezijwayelekile zokukhanyisa. UV Inspection Systems are automated Izinhlelo zokuhlola ezizenzakalelayo ze-UV fluorescence zenzekelayo ukulawulwa kwekhwalithi emigqeni yokukhiqiza.  Izici zihlanganisa: Izinhlelo zithole izicelo ezinkulu ezinhlelweni zokuhlola i-semiconductor UV, ukuhlolwa kwe-PCB UV, nokuhlolwa kwe-UV kwengxenye ebonakalayo ukuqinisekisa ukuhlolwa okuphezulu kwe-UV fluorescent. Materials Ukuhlolwa kwe-UV fluorescence kungashintshwa ezintweni ezithile: Ukuhlolwa kwe-UV kwezinsimbi - Imifantu, ubuso, nokutholwa ...
