He aha nga kaiwhakaahua whakaahua me te nui o to mohio mo nga kaiwhakaahua whakaahua? Ko nga Photoinitiators he momo puhui ka taea te tango i te kaha i tetahi roangaru i roto i te rohe ultraviolet (250-420nm) ranei e kitea ana (400-800nm), ka whakaputa i nga rauropi kore utu, nga kation, me etahi atu, na reira ka timata te monomer polymerization, te honohono, me te rongoa. . Heoi ano, he rereke nga roangaru e horomia ana e nga kaiwhakaahua rereke.
Ko te whakarōpūtanga o nga kaiwhakaahua whakaahua ka taea te wehewehe ki nga waahanga e rua: nga rauropi kore utu me nga momo katote. Ka taea te wehewehe i nga rauropi koreutu ki te Momo I me te Momo II; Ka taea te wehewehe i nga momo katote ki nga momo cationic me nga momo anionic. Ko te photoinitiator te timatanga o te hanga, a ko tana whakamahinga whakamutunga ka awehia e nga whakaritenga mahi me te punaha hanga. Ko te kaiwhakaahua whakaahua pai rawa atu, kaore he kaiwhakaahua whakaahua pai.
Ko nga kaiwhakaahua whakaahua kei te taha whakarunga i roto i te mekameka ahumahi. Ko nga rauemi mata kei roto i te mekameka umanga rongoa UV ko te nuinga o nga matū matū me nga matū motuhake, me nga photoinitiators kei te taha whakarunga o te mekameka ahumahi. Ka taea te whakamahi i te raupapa o te thiol pūhui hei rauemi mata mo te photoinitiators, ka whakamahia te nuinga i roto i nga mara o te rongoa me te hanga pesticide; Ka whakamahia nga kaiwhakaahua whakaahua ki nga waahi rereke penei i te photoresists me nga matū tautoko, nga paninga UV, nga waituhi UV, me etahi atu, me nga tono kapeka mo nga hua hiko, te whakapaipai o te whare me nga taonga hanga whare, rongoa me te maimoatanga hauora, aha atu.
He maha nga momo kaiwhakaahua whakaahua me te maha o nga whakamahinga, na me pehea e whiriwhiri ai? I muri mai, me korero atu ahau ki a koe me pehea te whiriwhiri i nga hua maha e kitea ana.
Tuatahi, e hiahia ana ahau ki te whakapuakikaiwhakaahua whakaahua 819, ka taea te whakamahi mo nga paninga kirihou rongoa UV tae. Ko nga paninga UV, na te pai o te mahi me te mahi pai, kua whakamahia nuitia ki runga i nga anga kirihou o nga momo taonga hiko me nga taputapu whare. Heoi, ko te whakakoi hohonu o nga paninga UV i muri i te tae kaore i te pai, ka puta he kino te piri o te kiriata me te ngoikore o te whakamararatanga me te whakaritenga o nga pigments e nga rei UV, ka tino pa ki te ahua o nga paninga, Na reira, ko te tikanga hanga tuku iho ko te whakamahi tuatahi i te whakarewa. te tuatahi o te tae mo te tae, katahi ka pania te parani UV i muri i te tunu hei whakapai ake i nga momo ahuatanga o te mata kiriata peita.
Kaihanga Whakaahua 184he kaitito whakaahua toka (I) momo toka toka me te kowhai me nga painga o te wa rokiroki roa, te pai o te tiimatanga, me te whanui o te awhe whakauru UV. Ka whakamahia te nuinga mo te whakamaoritanga UV o nga prepolymers haunga (pērā i te hākawa kiriaku) me te monomers vinyl mahi kotahi, maha ranei, me te oligomers, a he tino pai mo nga paninga me nga waituhi e hiahia ana ki te tohu kowhai teitei.
Photoinitiator TPO-Lhe ahua o te photoinitiator wai, e whakamahia ana i roto i te punaha whakatakotoranga me te iti o te kowhai me te iti o te kakara. Kei te whakamahia nuitia i roto i te waituhi mata hiraka, te waituhi tuhi Planographic, te waituhi flexographic, te photoresist, te varnish, te pereti me etahi atu mara.
Ko tephotoinitiator TPOte nuinga whakamahia i roto i ngā pūnaha ma, a ka taea te whakamahi i roto i UV rongoa paninga, waituhi tā, UV whakaora adhesives, paninga muka Optical, photoresists, pereti photopolymerization, resins stereolithographic, composites, whakakī niho, etc.
Ko te Photoinitiator 2959 he photoinitiator pai kore kowhai me te mahi nui, iti kakara, kore kowhai, iti pähekeheke, tauhou ki te hāora polymerization, me te mata tiketike pai whakaora. Ko nga roopu hydroxyl ahurei he ngawari te whakarewa i roto i nga paninga wai. He pai rawa mo nga esters kiriaku-wai me nga polyesters haunga. Ko te Photoinitiator 2959 he taapiri kua whakaaetia e te punaha tohu a te FDA mo te kore whakapiri tika ki te kai.
Benzophenonehe kaiwhakaahua whakaahua tuwhena kore utu e whakamahia ana i roto i nga punaha whakamaarama UV tuwhena kore utu penei i te paninga, te waituhi, te whakapiri, me etahi atu. Ko tenei hua ano he aukati polymerization styrene me te whakatikatika kakara, ka taea te kakara te kakara reka, ka whakamahia nuitia ki te hinu kakara me te hopi.
Ko nga hua e rite ana ki nga photoinitiators ko nga kaihoroi ultraviolet. I etahi wa, kaore e taea e te tangata te wehewehe i nga mea e rua.UV absorberska taea te whakakapi i nga kaiwhakaahua whakaahua. Na te mea ko nga kaihoroi UV te momo whakapumau marama e whakamahia nuitia ana ka taea te hototahi me te whakakapi ranei i nga photoinitiators hei whakamahi, a he tino pai hoki to raatau whai hua. Ko nga kaiwhakaahua whakaahua ka tino whakamahia mo te whakamaarama whakaahua, mo nga waituhi, paninga, ka taea hoki te whakamahi i nga waahi ahumahi me nga waahi hiko. He maha nga whakamahinga o nga kaihoroi UV, e whakamahia ana i roto i nga whakapaipai me nga whakaritenga o te kounga teitei. I tenei wa, he tino nui te utu o nga kaihoroi ultraviolet, i te mea he iti noa nga whakaahua. Ka taea e koe te whiriwhiri i nga hua e pa ana ki o hiahia.
