Chii chinonzi photoinitiators uye yakawanda sei yaunoziva nezve photoinitiators?Photoinitiators imhando yekomboni inogona kutora simba pane imwe wavelength muultraviolet (250-420nm) kana inooneka (400-800nm) dunhu, inogadzira mahara radicals, cations, nezvimwewo, uye nekudaro inotanga monomer polymerization, crosslinking, uye kurapa. .Nekudaro, iwo wavelengths anotorwa nemafotoinitiators akasiyana akasiyana.
Kurongeka kwemafotoinitiators kunogona kunyanya kukamurwa kuita zvikamu zviviri: mahara radicals uye ionic marudzi.Mahara radicals anogona kukamurwa kuva Type I uye Type II;Ionic mhando dzinogona kukamurwa kuita cationic uye anionic marudzi.Iyo photoinitiator ndiyo yekutanga kwekugadzirisa, uye kushandiswa kwayo kwekupedzisira kunokonzerwa nezvinodiwa zvekushanda uye maitiro ekugadzirisa.Pane chete akakodzera fotoinitiator, hapana akanakisa photoinitiator.
Photoinitiators iri kumusoro kwerukova muindasitiri yeketani.Izvo zvigadzirwa muUV yekurapa indasitiri cheni zvinonyanya kukosha zvemakemikari zvinhu uye makemikari akasarudzika, ane mafotoinitiators ari kumusoro kweiyo indasitiri ketani.Iyo yakatevedzana yetiol makomisheni inogona kushandiswa seyakagadzirwa zvigadzirwa zvemafotoinitiators, uye inonyanya kushandiswa muminda yemishonga nekugadzira mishonga yezvipembenene;Photoinitiators inoiswa munzvimbo dzakasiyana siyana senge photoresists uye anotsigira makemikari, UV coatings, UV ingi, nezvimwewo, ine terminal application inotenderera zvigadzirwa zvemagetsi, kushongedza kwemba uye zvekuvakisa, mushonga uye kurapwa, nezvimwe.
Kune marudzi akasiyana-siyana emafotoinitiators ane huwandu hwakawanda hwekushandisa, saka tinofanira kuvasarudza sei?Tevere, rega ndikuudze maitiro ekusarudza akati wandei anowanzo sangana zvigadzirwa.
Chekutanga, ndinoda kusumaphotoinitiator 819, iyo inogona kushandiswa kune mavara UV akapora epurasitiki coatings.Majeti eUV, nekuda kwekuita kwavo kwakanaka uye kugadzira kwakanaka, ave achishandiswa zvakanyanya pamabhomba epurasitiki emhando dzakasiyana dzemagetsi nemidziyo yemumba.Nekudaro, kusimba kwakadzika kweUV majasi mushure mekupenda hakuna kunaka, zvichikonzera kusasimba kwemafirimu uye kusapararira zvakanaka uye kurongeka kwepigment neUV resin, zvichikanganisa zvakanyanya kutaridzika kwejasi, Naizvozvo, maitiro echinyakare ekuvaka ndeyekutanga kushandisa solvent based. colored primer yekupendesa, wobva waisa UV varnish mushure mekubikira kuti uvandudze akasiyana emuviri zvimiro zvependi firimu pamusoro.
Photoinitiator 184inoshanda uye yero inodzivirira yemahara radical (I) mhando yakasimba photoinitiator ine mabhenefiti enguva refu yekuchengetedza, yakanyanya kutangisa kunyatsoita, uye yakafara UV yekunyudza renji.Iyo inonyanya kushandiswa kurapa UV yeunsaturated prepolymers (senge acrylic esters) pamwe chete kana akawanda anoshanda vinyl monomers uye oligomers, uye anonyanya kukodzera majasi neingi zvinoda yakakwira yellowing degree.
Photoinitiator TPO-Limhando yemvura photoinitiator, iyo inoshandiswa mukugadzira system ine yakaderera yellowness uye kunhuhwirira kwakaderera.Inowanzo shandiswa musilika screen printing inki, Planographic printing printing inki, flexographic printing inki, photoresist, varnish, printing plate nemamwe minda.
Thephotoinitiator TPOinonyanya kushandiswa muchena masisitimu, uye inogona kushandiswa muUV yekurapa machira, kudhinda ingi, UV kurapa anonamira, Optical fiber coatings, photoresists, photopolymerization mahwendefa, sterolithographic resins, composites, mazino anozadza, nezvimwe.
Photoinitiator 2959 inoshanda isina yellowing photoinitiator ine basa rakawanda, kunhuhwirira kwakaderera, kusatsvuka, kuderera kuderera, kusanzwa kune okisijeni polymerization, uye yakakwirira yekurapa kurapa.Akasarudzika hydroxyl mapoka anonyungudika zviri nyore mumvura-based coatings.Kunyanya akakodzera mvura-based acrylic esters uye unsaturated polyesters.Photoinitiator 2959 zvakare inonamira yakabvumidzwa neFDA certification system yekusasangana yakananga nechikafu.
Benzophenonendeye yemahara radical photoinitiator inonyanya kushandiswa mumahara radical UV yekurapa masisitimu akadai semajasi, ingi, zvinonamira, nezvimwe. Iyo zvakare iri yepakati mune organic pigments, mishonga, zvinonhuwira, uye mishonga yezvipembenene.Ichi chigadzirwa zvakare styrene polymerization inhibitor uye inonhuhwirira inogadzirisa, iyo inogona kupa kunhuhwirira kunaka kutapira, uye inoshandiswa zvakanyanya muzvinonhuwira uye sipo essence.
Zvigadzirwa zvakafanana ne photoinitiators ndeye ultraviolet absorbers.Dzimwe nguva, vanhu kazhinji havagone kusiyanisa pakati pezviviri izvi.UV absorbersinogona kutsiva photoinitiators.Nekuti maAbsorber eUV ndiyo inonyanya kushandiswa mhando yemwenje stabilizer uye inogona kuenderana kana kutsiva photoinitiators kuti ishandiswe, uye kushanda kwavo kwakanaka kwazvo.Photoinitiators anonyanya kushandiswa kufotocuring, yeinki, machira, uye anogona zvakare kushandiswa mumaindasitiri nemagetsi minda.UV absorbers ane huwandu hwakakura hwekushandisa, hunonyanya kushandiswa muzvizoro nemhando yepamusoro zvinodiwa.Zvichakadaro, mutengo we ultraviolet absorbers wakakwirira, nepo photoinitiators zvishoma.Unogona kusarudza zvigadzirwa zvinoenderana nezvinodiwa zvako.
Isu tiri nyanzvi yekugadzira mugadziri.Pamusoro pezvigadzirwa zvataurwa pamusoro apa, isu zvakare tine zvinotevera zvigadzirwa zvakafanana:
