Ukwaleka kweUV (UV) luhlobo olutsha lokwaleka kokusingqongileyo.Isantya sokumisa kwayo sikhawuleza kakhulu.Inokunyangwa kukukhanya kwe-UV kwimizuzwana embalwa, kwaye ukusebenza kakuhle kwemveliso kuphezulu.
Iingubo zokunyanga ze-UV zenziwa ikakhulu ngama-oligomers, i-diluents esebenzayo, ii-photoinitiators kunye nezongezo.
1. Oligomer
Ifilimu yokwenza ifilimu iyona nxalenye ephambili yokwaleka, eyona nto iyinxalenye yolwelo.Ukusebenza kwefilimu, ukusebenza kokwakhiwa kunye nezinye iipropati ezikhethekileyo zokugquma ikakhulu zixhomekeke kwizinto zokwenza ifilimu.Ifilimu yokwenza ifilimu yokugqoka i-UV yi-oligomer, kwaye ukusebenza kwayo ngokusisiseko kumisela ukusebenza kolwakhiwo kunye nesantya sokukhanya sokukhanya kwengubo ngaphambi kokunyanga, ukusebenza kwefilimu emva kokunyanga kunye nezinye iimpawu ezikhethekileyo.
Iingubo ze-UV ubukhulu becala ziinkqubo zokunyanga ukukhanya kweradical, ke ii-oligomers ezisetyenzisiweyo zizo zonke iintlobo zeereyini ze-acrylic.I-Cationic UV yokugquma iioligomers ziyi-epoxy resin kunye ne-vinyl ether compounds.
2.I-diluent esebenzayo
I-diluent esebenzayo lelinye icandelo elibalulekileyo lotyatyazo lwe-UV.Iyakwazi ukuhlambulula kunye nokunciphisa i-viscosity, kwaye nayo inepropati yokulungelelanisa ifilimu yokunyanga.Iimonomers ezisebenzayo ze-Acrylate zine-reactivity ephezulu kunye nokuguquguquka okuphantsi, ngoko ke zisetyenziswa ngokubanzi kwiingubo ze-UV.I-Acrylic esters isetyenziswa njenge-diluent esebenzayo kwiingubo ze-UV.Kwifomula yokwenyani, i-mono -, i-acrylates esebenza kabini kunye ne-multi-functional iya kusetyenziswa kunye ukwenza iipropathi zabo zihambelane kwaye zifezekise injongo yesiphumo esihle esibanzi.
3. Ifotoinitiator
I-Photoinitiator yinto ekhethekileyo yokuvuselela ii-UV.Lilungu elibalulekileyo leengubo ze-UV kwaye limisela izinga lokunyanga le-UV leengubo ze-UV.
Kwivarnish engenambala yeengubo ze-UV, i-1173, 184, 651 kunye ne-bp / i-amine ephezulu zihlala zisetyenziswa njenge-photoinitiators.I-184 inomsebenzi ophezulu, ivumba eliphantsi kunye nokuchasana nokutyheli, yeyona nto ikhethiweyo yefotonitiator yokugquma kwe-UV enganyangekiyo.Ukuze kuphuculwe izinga lokunyanga ukukhanya, lihlala lisetyenziswa ngokudibanisa ne-TPO.
Kwiingubo ze-UV ezinemibala, i-photoinitiators kufuneka ibe yi-itx, i-907, i-369, i-TPO, i-819, njl. Ngamanye amaxesha, ukuze kuncitshiswe i-oxygen polymerization inhibition kunye nokuphucula izinga lokunyanga kwe-UV, inani elincinci le-amine esebenzayo lihlala lidityaniswa kwiingubo ze-UV.
4. Izongezo
Izongezo zizinto ezincedisayo kwiingubo ze-UV.Indima yezongezo kukuphucula ukusebenza kokucubungula, ukugcinwa kokugcinwa kunye nokusebenza kokwakhiwa kwengubo, ukuphucula ukusebenza kwefilimu kunye nokunika ifilimu ngemisebenzi ekhethekileyo.Izongezo ezisetyenziswa ngokuqhelekileyo kwiingubo ze-UV ziquka i-defoamer, i-ejenti yokulinganisa, i-disperant yokumanzisa, umgqugquzeli wokubambelela, i-agent yokulinganisa, i-polymerization inhibitor, njl., edlala indima eyahlukileyo kwiingubo ze-UV.
