Inqubo yokuphulukisa i-UV yobuchwepheshe bokunamathisela iqukethe izinyathelo ezine eziyisisekelo: Isicelo Sokunamathisela: I-glue ezwela ukukhanya noma i-UV adhesive ibekwe ebusweni bokubopha, okungaba ingilazi, ipulasitiki, insimbi, noma izinhlanganisela. Ukuqondanisa: Izakhi zibekwa endaweni ngendlela eqondile kakhulu ukuze kufinyelelwe ngisho nokuxhumana phakathi kwezingqimba zokunamathisela. Ukuchayeka kokukhanya kwe-UV: Uhlelo lokuphulukisa lwe-UV LED noma uhlelo lwesibani sokuphulukisa i-UV luwumthombo wama-wavelengths athile (imvamisa i-365nm noma i-395nm) ukwenza kusebenze ama-photoinitiators. Ukwelapha nokuqina: I-photopolymerized adhesive ithatha imizuzwana embalwa ukwelapha, futhi ingaphulukisa ngokuphelele ngobuqotho obuvelele besibopho esivelele. Yonke inqubo izosusa ukusetshenziswa kokuphulukisa ukushisa noma isikhathi eside sokumiswa futhi inikeze ubuchwepheshe bokunamathisela obusheshayo, obuthuthukisa ukusebenza kahle kokukhiqiza futhi bunciphise ukusetshenziswa kwamandla. UV-Curable Adhesives are of various types I-UV-Epoxy Resins Izinamathiselo ezenziwe nge-epoxy zilungele kakhulu ukubopha kwesakhiwo lapho kudingeka khona amandla aphezulu okubopha lapho usebenza ngokukhanya kwe-UV. Esinye sezicelo ezijwayelekile ekwenzeni i-elekthronikhi nasekukhiqizeni izimoto. I-Acrylic Acids, Ukunamathela Okuphulukisayo kwe-UV Ama-Acrylics nawo ayaziwa ukuthi anejubane eliphakeme le-ejenti yokubopha kanye nokuphulukiswa kokushisa okuphansi kwe-UV, okusetshenziselwa ukubopha i-lens optical kanye nokukhiqizwa kwezingxenye zepulasitiki. Izindlela zokusebenzisa i-UV-Curable Pressure-Sensitive Adhesives (PSA) Lezi zinamathelayo zingasetshenziswa emaphaketheni nasezinhlosweni zokulebula, futhi zinikeze izixazululo ezisheshayo ekuhlanganisweni kwe-UV ezingenakukhishwa futhi zingagugi.  I-Polyurethane ne-UV-Curable silicone Adhesives Ukusetshenziswa kwazo kuyaguquguquka, kunembile ekuhlanganisweni kwe-UV, futhi kuyahambisana ne-biocompatible; lokhu kubenza babe balulekile ezinqubweni zokubopha i-aerospace namadivayisi wezokwelapha. ...

Ukufeza ukwelashwa kwezimboni okuphezulu kuncike ekuqondaneni okuqondile phakathi komthombo wakho wokukhanya kanye namakhemikhali wezinto zakho. Uzothola ukuthi nje ukuba nesibani esinamandla akwanele; Ukukhanya kufanele "kulungiswe" kumakhemikhali athile aklanyelwe ukuqinisa ama-inki akho noma ama-adhesives. Lo mhlahlandlela uchaza ukuthi ungaqhathanisa kanjani ama-photoinitiators kuma-wavelengths e-UV LED ngokuhlola i-spectra yokumuncwa namaphrofayli wamandla. Ngokuqonda lokhu kubhangqa kwezobuchwepheshe, ungaqinisekisa isivinini sokukhiqiza esisheshayo, izibopho eziqinile, kanye nenqubo yokukhiqiza enokwethenjelwa kakhulu. Kusho ukuthini ukufanisa ama-photoinitiators kuma-wavelengths e-UV LED? Ukufanisa ama-photoinitiators kuma-wavelengths e-UV LED kusho ukukhetha abaqalayo abaneziqongo zokumuncwa ezihlangana nebanga lokukhishwa kwe-LED. Kufanele uqinisekise ukuthi "umbala" othile wokukhanya kwe-ultraviolet okhishwa ngama-diode akho imvamisa efanayo ne-photoinitiator yakho eyenzelwe ukuyibamba. Ngoba ama-LED akhipha ibhande elincane kakhulu lokukhanya - ngokungafani ne-spectrum ebanzi yezibani zendabuko - lokhu kugqagqana kubalulekile. Uma okukhiphayo LED iwela ngaphandle kwewindi lokumuncwa komqalisi, amandla azodlula ezintweni ngaphandle kokuvusa inqubo yokuqina, kungakhathaliseki ukuthi isibani sinamandla kangakanani. Ama-photoinitiators asebenzisana kanjani nokukhanya kwe-UV? Ama-photoinitiators asebenza ngokumunca ama-wavelengths athile e-UV futhi aguqule lawo mandla abe ngama-radicals noma ama-ion aqala i-polymerization. Lapho uveza ukumbozwa kwakho uketshezi emvamisa efanele ye-UV, ama-molecule we-photoinitiator athatha ama-photon futhi angene esimweni esisebenzayo kakhulu. Lokhu kudluliswa kwamandla kuphula izibopho zamakhemikhali ngaphakathi kwe-initiator, ukudala izinhlobo ezisebenzayo ezidingekayo ukuxhuma ama-monomers kuchungechunge oluqinile lwe-polymer. Ungabuka i-photoinitiator njenge "spark plug" yokusabela kwamakhemikhali; kudinga ...
