Abstract
Ubuchwepheshe bokwelapha be-Ultraviolet (UV), njengenqubo ephumelelayo, ehambisana nemvelo, kanye neyonga amandla, buthole ukunakwa okubalulekile eminyakeni yamuva nje. Le ndatshana ihlinzeka ngesifinyezo sobuchwepheshe bokuphulukisa be-UV, ehlanganisa izimiso zayo eziyisisekelo, izingxenye ezibalulekile, izinhlelo zokusebenza, izinzuzo, imikhawulo, kanye nezitayela zokuthuthuka zesikhathi esizayo.
1. Isingeniso
Ukwelashwa kwe-UV kuyinqubo ye-photochemical lapho ukukhanya kwe-ultraviolet kusetshenziswa khona ukuqalisa ukusabela kwe-polymerization okuguqula ama-monomers awuketshezi noma ama-oligomers abe i-polymer eqinile. Lobu buchwepheshe bokuphulukisa ngokushesha sebuyingxenye ebalulekile yezimboni ezihlukahlukene, okuhlanganisa okokunamathela, okokunamathisela, oyinki, nogesi.
2. Okuyisisekelo kwe-UV Curing Technology
Isimiso: Ukwelapha kwe-UV kuncike kuma-photoinitiators, abamba ukukhanya kwe-UV futhi akhiqize izinhlobo ezisebenzayo njengama-radicals mahhala noma ama-cations ukuze aqalise u-polymerization.
Izingxenye Ezibalulekile:
1.1. Ama-Photoinitiators: Ahlukaniswe abe izinhlobo zamahhala ze-radical kanye ne-cationic.
2.2. Ama-Monomers nama-Oligomers: Thola izici zomshini namakhemikhali zomkhiqizo wokugcina.
3.3. Imithombo Yokukhanya kwe-UV: Ngokwesiko amalambu e-mercury; manje iya ngokuya ikhula imithombo ye-UV ye-LED ngenxa yokusebenza kahle kwamandla nempilo ende.
3. Ukusetshenziswa kwe-UV Curing Technology
Ama-coatings: ama-wood finishes, ama-auto coatings, nezingqimba zokuzivikela.
Oyinki: Ukuphrinta kwedijithali, ukupakisha, namalebula.
Ama-Adhesives: Asetshenziswa ku-electronics, optics, namadivayisi wezokwelapha.
Ukuphrinta kwe-3D: Ama-resin elapheka nge-UV abalulekile ku-stereolithography kanye nokucubungula ukukhanya kwedijithali (DLP).
4. Izinzuzo ze-UV Curing Technology
Isivinini: Ukwelapha ngokushesha ngemizuzwana.
Ukusebenza Kwamandla: Isebenza emazingeni okushisa aphansi ngokusetshenziswa kwamandla okuncishisiwe.
Ubungane Bemvelo: Amasistimu angancibilikisiwe anciphisa ukukhishwa kwe-VOC.
Ukusebenza Okuphezulu: Inikeza ubulukhuni obuhle kakhulu, ukunamathela, nokumelana namakhemikhali.
5. Imikhawulo kanye Nezinselele
Izithiyo Zezinto Ezibalulekile: Ukwelashwa kwe-UV kukhawulelwe ezintweni ezibonisa ngale noma ezincane ze-UV.
Izindleko: Ukusethwa kokuqala kwezinhlelo zokuphulukisa ze-UV kungaba phezulu.
Impilo Nokuphepha: Izingozi zokuvezwa kwe-UV kanye nokufuduka kwe-photoinitiator ezinhlelweni ezibucayi ezifana nokupakishwa kokudla.
6. Amathemba Ekusasa
Intuthuko kubuchwepheshe be-UV LED: Ukuthuthukiswa kwe-wavelength tunability, ukusebenza kahle kwamandla, nezindleko eziphansi kuqhuba ukwamukelwa.
Ukuthuthukiswa Kwama-Photoinitiators Amasha: Gxila ekufudukeni okuncane, iziqalisi eziphephile ekudleni ukuze kunwetshwe izinhlelo zokusebenza.
Ukuhlanganiswa nobuchwepheshe obusafufusa: Ukuhlanganisa ukuphulukiswa kwe-UV nokukhiqiza okungeziwe, okokunamathela okuhlakaniphile, nezinto zikagesi eziguquguqukayo.
Ukugxila Kokusimama: Ama-resin asekelwe ku-Bio-based kanye nama-photoinitiators ukuze ahambisane nemigomo yokusimama komhlaba wonke.
7. Isiphetho
Ubuchwepheshe bokwelapha be-UV buguqule izimboni ngejubane, ukusebenza kahle, kanye nobungane bemvelo. Naphezu kwezinselelo, ukusungulwa okusha okuqhubekayo kwezinto zokwakha, imithombo yokukhanya, nezinhlelo zokusebenza kuthembisa ikusasa eliqhakazile lokwelashwa kwe-UV, okuyenza ikwazi ukuhlangabezana nezidingo zokukhiqiza zesimanje kanye nentuthuko esimeme.
