Ngaba Uyazi NgeFotoinitiator

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.
