Yintoni iifotoinitiators kwaye ungakanani ulwazi malunga neefotoinitiators?I-Photoinitiators luhlobo lwekhompawundi olukwazi ukufumana amandla kwi-wavelength ethile kwi-ultraviolet (250-420nm) okanye ebonakalayo (400-800nm) kummandla, ukuvelisa i-radicals yamahhala, i-cations, njl., kwaye ngaloo ndlela iqalise i-polymerization ye-monomer, i-crosslinking, kunye nokunyanga. .Nangona kunjalo, amaza amaza afunnwe ziifotonitiators ezahlukeneyo ahlukile.
Ukuhlelwa kweefotonitiators kunokwahlulwa ikakhulu kwiindidi ezimbini: i-radicals yamahhala kunye neentlobo ze-ionic.I-radicals yamahhala ingahlulwa ibe yi-Type I kunye ne-Type II;Iintlobo ze-Ionic zinokwahlulwa zibe ziintlobo ze-cationic kunye ne-anionic.I-photoinitiator yindawo yokuqala yokuqulunqwa, kwaye ukusetyenziswa kwayo kokugqibela kuphenjelelwa ziimfuno zokusebenza kunye nenkqubo yokuqulunqa.Kukho kuphela eyona photoinitiator ifanelekileyo, akukho photoinitiator ilungileyo.
Iifotonitia zibekwe phezulu kumjelo weshishini.Iimathiriyeli ekrwada kwikhonkco leshishini lokunyanga i-UV zisisiseko sezinto zekhemikhali kunye neekhemikhali ezikhethekileyo, ezineefotoinitiators ezibekwe phezulu kumxokelelwane woshishino.Uluhlu lweekhompawundi ze-thiol zingasetyenziswa njengezinto eziluhlaza kwiifotonitiators, kwaye zisetyenziswa kakhulu kwiinkalo zonyango kunye nokwenziwa kwe-pesticide;Iifotonitiators zisetyenziswa kwiinkalo ezahlukeneyo ezinje ngeefotoresist kunye neekhemikhali ezixhasayo, iingubo ze-UV, ii-ink ze-UV, njl.
Kukho iindidi ngeendidi zeefotonitiators ezinoluhlu olubanzi losetyenziso, ngoko ke kufuneka sizikhethe njani?Okulandelayo, mandikuxelele indlela yokukhetha iimveliso ezininzi eziqhelekileyo.
Okokuqala, ndingathanda ukwazisaifotoinitiator 819, enokuthi isetyenziswe kwiiplastiki ezinemibala e-UV ephilisayo.Iingubo ze-UV, ngenxa yokusebenza kwazo okugqwesileyo kunye nemveliso esebenzayo, zisetyenziswe ngokubanzi kumaqokobhe eplastiki eemveliso ezahlukeneyo zombane kunye nezixhobo zasekhaya.Nangona kunjalo, ukuqiniswa okunzulu kweengubo ze-UV emva kokufakwa kwemibala akulunganga, okukhokelela ekunamatheleni kwefilimu okungahambi kakuhle kunye nokusasazwa kakubi kunye nokulungelelaniswa kweepigments ngeereyini ze-UV, okuchaphazela kakhulu inkangeleko yeengubo, Ke ngoko, inkqubo yokwakha yemveli kukuqala ukusebenzisa isinyibilikisi esekwe. I-primer enemibala yokufaka imibala, emva koko sebenzisa ivanishi ye-UV emva kokubhaka ukuphucula iimpawu ezibonakalayo zomphezulu wefilimu yepeyinti.
Ifotoinitiator 184Isebenza kakuhle kwaye ityheli ukumelana ne-radical yasimahla (I) yohlobo lwefotoinitiator eqinileyo enezibonelelo zexesha elide lokugcina, ukusebenza kakuhle kokuqaliswa, kunye noluhlu olubanzi lokufunxa kwe-UV.Isetyenziselwa ikakhulu ukunyangwa kwe-UV yee-prepolymers ezingaxutywanga (ezifana ne-acrylic esters) kunye ne-vinyl monomers kunye ne-oligomers esebenzayo enye okanye emininzi, kwaye ilungele kakhulu ii-coatings kunye nee-inki ezifuna idigri ephezulu ye-yellowing.
Ifotoinitiator TPO-Lluhlobo lwe-photoinitiator yolwelo, esetyenziswa kwinkqubo yokuqulunqa kunye ne-yellowness ephantsi kunye nevumba eliphantsi.Isetyenziswa ngokuqhelekileyo kwi-inki yokuprinta kwesikrini sesilika, i-Planographic printing inki, i-flexographic printing inki, i-photoresist, ivanishi, ipleyiti yokushicilela kunye nezinye iindawo.
Iifotoinitiator TPOisetyenziswa kakhulu kwiinkqubo ezimhlophe, kwaye inokusetyenziswa kwiingubo zokunyanga ze-UV, ii-inki zokuprinta, izinto zokuncamathelisa i-UV, i-Optical fiber coatings, i-photoresists, iipleyiti zefotopolymerization, iiresin zesterolithographic, i-composites, izihluzi zamazinyo, njl.
I-Photoinitiator 2959 yifotoinitiator esebenzayo engekho tyheli enomsebenzi ophezulu, ivumba eliphantsi, i-non yellowing, i-volatility ephantsi, ukungabi naluvelwano kwi-oxygen polymerization, kunye nokusebenza kakuhle kokunyanga komhlaba.Amaqela awodwa e-hydroxyl anyibilika ngokulula kwiingubo ezisekwe emanzini.Ngokukodwa ezifanelekileyo kwii-esters ze-acrylic ezisekelwe emanzini kunye ne-polyester ezingaxutywanga.I-Photoinitiator 2959 ikwayinto encamathelayo evunywe yinkqubo yesatifikethi ye-FDA yokunxibelelana ngokuthe ngqo nokutya.
Benzophenoneyifotoinitiator yasimahla yeradical esetyenziswa ikakhulu kwiinkqubo zokunyanga ze-UV zasimahla ezifana neengubo, ii-inki, izinto zokuncamathelisa, njl.Le mveliso ikwayi-styrene polymerization inhibitor kunye ne-fragrance fixative, enokunika ivumba elimnandi, kwaye isetyenziswa ngokubanzi kwi-perfume kunye nesepha essence.
Iimveliso ezifana ne-photoinitiators zithatha i-ultraviolet absorbers.Ngamanye amaxesha, abantu bahlala bengakwazi ukwahlula phakathi kwezi zimbini.iAbsorber UVinokutshintsha iifotonitiators.Ngenxa yokuba i-Absorbers ye-UV yolona hlobo lusetyenziswa kakhulu lwe-stabilizer yokukhanya kwaye inokuhambelana okanye ithathe indawo ye-photoinitiators ukuze isetyenziswe, kunye nokusebenza kwazo kuhle kakhulu.Iifotonitiators zisetyenziselwa ngokukodwa ukufota, ii-inki, iingubo, kwaye zinokusetyenziswa kwiindawo zoshishino kunye ne-elektroniki.I-Absorbers ye-UV inoluhlu olukhulu lokusetyenziswa, ikakhulu olusetyenziswa kwizithambiso ezineemfuno eziphezulu.Okwangoku, ixabiso le-absorber ultraviolet liphezulu, ngelixa i-photoinitiators iphantsi.Unokukhetha iimveliso ezihambelanayo ngokusekelwe kwiimfuno zakho.
