Waa maxay photoinitiators iyo intee in le'eg ayaad ka taqaanaa sawir-qaadayaasha? Photoinitiators waa nooc ka mid ah isku-darka kaas oo nuugi kara tamarta mawjada dhererka qaarkood ee ultraviolet (250-420nm) ama muuqata (400-800nm) gobolka, waxay abuuraan xagjirnimo bilaash ah, cations, iwm. . Si kastaba ha ahaatee, hirarka dhaadheer ee ay nuugaan sawir-qaadayaasha kala duwan ayaa kala duwan.
Kala soocida photoinitiators waxaa inta badan loo qaybin karaa laba qaybood: xagjirrada xorta ah iyo noocyada ionic. Xagjirrada xorta ah waxaa loo qaybin karaa Nooca I iyo Nooca II; Noocyada Ionic waxaa loo qaybin karaa noocyo cationic iyo anionic. Photoinitiator-ku waa meesha laga bilaabayo samaynta, isticmaalkeeda ugu dambeeyana waxaa saameeya shuruudaha waxqabadka iyo nidaamka qaabaynta. Waxaa jira kaliya sawir-qaade ugu habboon, ma jiro sawir-qaade ugu fiican.
Photoinitiators waxay ku yaalliin xagga sare ee silsiladda warshadaha. Alaabta ceeriin ee silsiladda warshadaynta UV inta badan waa agab kiimiko oo aasaasi ah iyo kiimikooyin khaas ah, oo leh sawir-qaadayaal ku yaal xagga sare ee silsiladda warshadaha. Xeryahooda taxanaha ah ee thiol waxaa loo isticmaali karaa sidii alaabta ceeriin ee sawir-qaadayaasha, waxaana inta badan loo adeegsadaa dhinacyada daawada iyo soo saarista sunta cayayaanka; Photoinitiators waxaa lagu dabaqaa dhinacyo kala duwan sida sawir-qaadista iyo kiimikooyinka taageeraya, dahaarka UV, khadadka UV, iwm.
Waxaa jira noocyo kala duwan oo photoinitiators ah oo leh adeegsi badan, markaa sidee ayaan u dooranaa? Marka xigta, aan kuu sheego sida loo doorto dhowr badeecadood oo caadi ahaan la kulmo.
Marka hore, waxaan jeclaan lahaa inaan baroPhotoinitiator 819, kaas oo loo isticmaali karo midabada UV ee daahan caag ah. Dahaarka UV, oo ay ugu wacan tahay waxqabadkooda wanaagsan iyo wax-soo-saarka hufan, ayaa si weyn loogu isticmaalay qolof balaastiig ah oo alaabooyin elektaroonik ah iyo qalab guri oo kala duwan ah. Si kastaba ha ahaatee, adkaynta qoto dheer ee daahan UV ka dib markii midabaynta ma wanaagsana, taasoo keentay in adhesion film liidata iyo kala firidhsan liidata iyo habaynta pigments by resins UV, si dhab ah u saameeya muuqaalka kore ee daahan, Sidaa darteed, habka dhismaha dhaqameed waa in marka hore codsan dareere ku salaysan. Primer midab leh oo midabaynta, ka dibna mari varnish UV ka dib dubista si loo hagaajiyo sifooyinka jireed ee kala duwan ee dusha filimka rinjiga.
Sawir qaade 184waa sawir-qaade adag oo wax ku ool ah oo u adkaysta nooca bilaashka ah (I) oo leh faa'iidooyinka wakhtiga kaydinta dheer, waxtarka bilowga sare, iyo nuugista UV ballaaran. Waxaa inta badan loo isticmaalaa daawaynta UV ee prepolymers unnsaturated (sida acrylic esters) oo ay la socdaan hal ama multi functional vinyl monomers iyo oligomers, oo waxay si gaar ah ugu habboon dahaarka iyo khadadka u baahan shahaado huruud sare.
Sawir qaade TPO-Lwaa nooc ka mid ah dareeraha dareeraha ah ee dareeraha ah, kaas oo loo isticmaalo nidaamka qaabeynta oo leh jaalle hoose iyo ur yar. Waxaa caadi ahaan loo isticmaalaa khad daabacaadda shaashadda xariirta, qalin daabacaadda Planographic, qalin daabacaadda flexographic, sawir-qaadista, varnish, saxanka daabacaadda iyo meelo kale.
Thesawir qaade TPOwaxaa inta badan loo isticmaalaa in nidaamka cad, oo waxaa loo isticmaali karaa in daahan UV-daawaynta, daabacaadda khad, UV daawaynta adhesives, daahan fiber indhaha, photoresists, taarikada photopolymerization, resins stereolithographic, composites, buuxinta ilkaha, iwm.
Photoinitiator 2959 waa sawir-qaade hufan oo aan jaalle lahayn oo leh hawl sare, ur yar, jaale-la'aan, isbeddel hoose, dareen la'aan polymerization oxygen, iyo waxtarka bogsashada sare ee dusha sare. Kooxo hydroxyl gaar ah oo si fudud ugu milmay dahaadhka biyaha ku salaysan. Gaar ahaan ku habboon esters acrylic-ku-salaysan biyaha iyo polyester-yada aan saturated ahayn. Photoinitiator 2959 sidoo kale waa xabag ay ansixisay nidaamka shahaadada FDA ee xiriirka aan tooska ahayn ee cuntada.
Benzophenonewaa sawir qaade xagjir ah oo xor ah oo inta badan loo isticmaalo hababka daaweynta UV ee xorta ah sida dahaarka, khadadka, xabagta, iwm. Sidoo kale waa dhexdhexaad midabada organic, daawooyinka, uunsiga, iyo cayayaanka. Alaabtani sidoo kale waa styrene polymerization inhibitor iyo hagaajinta udgoonka, kaas oo siin kara udgoonka dhadhan macaan, waxaana si weyn loogu isticmaalaa cadarka iyo nuxurka saabuunta.
Alaabooyinka la midka ah sawir-qaadayaasha waa kuwa nuugaya ultraviolet. Mararka qaarkood, dadku inta badan ma kala saari karaan labada.Nuugayaasha UVbedeli kara photoinitiators. Sababtoo ah nuugayaasha UV waa nooca ugu badan ee loo isticmaalo xasilinta iftiinka waxayna la jaan qaadi karaan ama bedeli karaan sawir-qaadayaasha si loo isticmaalo, waxtarkoodu sidoo kale waa mid aad u wanaagsan. Photoinitiators ayaa si gaar ah loogu isticmaalaa sawir-qaadista, khadadka, dahaarka, waxaana sidoo kale loo isticmaali karaa goobaha warshadaha iyo elektiroonigga ah. Nuugayaasha UV waxay leeyihiin adeegsi aad u tiro badan, oo inta badan loo isticmaalo waxyaabaha la isku qurxiyo ee leh shuruudo tayo sare leh. Dhanka kale, qiimaha nuugayaasha ultraviolet waa mid aad u sarreeya, halka sawir-qaadayaashu ay yihiin kuwo hooseeya. Waxaad dooran kartaa alaabada u dhiganta iyadoo ku saleysan baahidaada.
Waxaan nahay soo-saare xirfad-abuure leh. Marka laga soo tago alaabooyinka aan kor ku soo sheegnay, waxaan sidoo kale haysanaa alaabooyinkan la midka ah:
