I-Adhesive ye-UV kukongeza i-photoinitiator (okanye i-photosensitizer) kwi-resin ngefomula ekhethekileyo.Emva kokufunxa ukukhanya okuphezulu kwe-ultraviolet kwi-ultraviolet (UV) izixhobo zokunyanga, iya kuvelisa i-radicals yamahhala esebenzayo okanye i-ionic radicals, ukuze iqalise i-polymerization, i-cross-linking kunye ne-grafting reactions, ukuze i-resin (i-UV yokugqoka, i-inki) i-adhesive, njl. njl.) inokuguqulwa ukusuka kulwelo ukuya kwisiqina phakathi kwemizuzwana embalwa (ukusuka).Le nkqubo yotshintsho ibizwa ngokuba "yi-UV curing".
1, Izinto eziluncedo zokuncamathelisa UV:
1. I-Adhesive ye-UV ayinayo i-VOCs eguquguqukayo kwaye ayinakho ungcoliseko emoyeni.Amacandelo okuqulunqwa kwe-adhesive ye-UV ayinqabile okanye ithintelwe kuyo yonke imimiselo yokusingqongileyo, kwaye ayinayo i-solvent kunye nokutsha okuphantsi.Ukuthobela ukugcinwa ngokukhuselekileyo kunye nemigaqo yokuthutha.
2. Isantya sokunyanga sokuncamathelisa kwe-UV sikhawuleza kakhulu.Ukusebenzisa izixhobo zokunyanga ze-UV ezinamandla ahlukeneyo kunokunyanga ngokupheleleyo kwimizuzwana embalwa ukuya kwimizuzu, ephucula kakhulu ukusebenza kakuhle kwemveliso yamashishini okuvelisa.Ifanelekile kakhulu kwimveliso yomgca wokuhlanganisana ngokuzenzekelayo.Emva kokuba i-Adhesive ye-UV iphilisiwe, inokwenza ngokukhawuleza uvavanyo lokusebenza kokunamathela, ukupakishwa kwemveliso kunye nokuthunyelwa kokuthunyelwa, ukugcina indawo yomgangatho weemveliso ezigqityiweyo kunye nezigqityiweyo.Izixhobo ezisetyenziswa kwinkqubo yokunyanga ye-UV ngokubanzi zinamandla aphantsi, agcina amandla abalulekileyo.Xa kuthelekiswa nokuncamathelisa kokunyanga ubushushu, amandla asetyenziswa ngokusebenzisa i-UV encamathelayo yokunyanga inokugcina i-90% yokusetyenziswa kwamandla.Ukongeza, izixhobo zokunyanga ze-UV zinesakhiwo esilula, indawo encinci yomgangatho kwaye igcina indawo yokusebenza.
3. I-adhesive ye-UV ingasetyenziswa ngokuguquguqukayo phantsi kweemeko ezahlukeneyo zokusingqongileyo kunye neemfuno.Ixesha lokunyanga kunye nexesha lokulinda linokulungiswa ngokweemfuno.Iqondo lokunyanga le-Adhesive ye-UV inokulungelelaniswa ngokuthanda kwaye ingasetyenziswa ngokuphindaphindiweyo kwaye inyangwe.Izisa lula kulawulo lwemveliso.Isibane sokunyanga kwe-UV sinokufakelwa ngokufanelekileyo kumgca wokuvelisa okhoyo ngokwemeko yangempela.Ayifuni ukulungiswa okukhulu kunye nokuguqulwa.Ine-flexibility yokuba i-adhesives eqhelekileyo ayinakuthelekisa.
2, Ububi bokuncamathelisa kwe-UV:
1. Iindleko zemathiriyeli ekrwada ye-UV yokuncamathelisa iphezulu ngokubanzi.Ekubeni azikho i-solvents ephantsi kwexabiso eliphantsi kunye nezihluzi kwizithako, iindleko zokuvelisa i-Adhesives ze-UV ziphezulu kunezo zincamathelisi eziqhelekileyo, kwaye ixabiso lokuthengisa elihambelanayo nalo liphezulu.
2. Ukungena kwemitha ye-ultraviolet kwezinye iiplastiki okanye izinto eziguquguqukayo azinamandla, ubunzulu bokunyanga bukhawulelwe, kwaye ijometri yezinto ezinyangekayo zixhomekeke kwimiqobo ethile.Amalungu angenako ukuhlanjululwa yi-ultraviolet ray akulula ukugqitywa ngexesha elinye, kwaye iindawo ezingabonakaliyo azilulanga ukunyangwa.
3. Izinto zokuncamathelisa eziqhelekileyo ze-UV zingasetyenziselwa kuphela ukudibanisa izinto ezithile zokuhambisa ukukhanya.Ukudibanisa izixhobo zokuhambisa ukukhanya kufuna indibaniselwano yezinye iindlela zokunyanga, ezinje ngonyango lwe-cationic, ukufudumeza kwe-UV ukunyanga kabini, ukunyangeka kwe-UV ukunyanga kabini, ukuphiliswa kabini kwe-UV anaerobic, njl.
Lonke uthotho lweemveliso zophawu lwe-Shenzhen Zicai zisetyenziswa kakhulu kwimimandla eyahlukeneyo yemizi-mveliso, enje ngeengubo ezahlukeneyo ezinyangekayo ze-UV, ii-inki ezinyangekayo ze-UV, izinto zokuncamathelisa ezinyangekayo ze-UV, iimveliso ze-elektroniki ze-3C, iimoto zangaphakathi kunye neenxalenye ze-trim zangaphandle, kunye nokuqina komphezulu kunye nonyango oluxhathisayo. yeefilimu ezahlukeneyo ezisebenzayo.
