Tekinolosi faʻamalama malamalama o se maualuga-lelei, puipuiga o le siʻosiʻomaga, faʻasaoina o le malosi ma le maualuga o mea faʻatekonolosi luga.Ua lauiloa o se tekinolosi fou mo alamanuia lanu meamata i le 21st seneturi.Faatasi ai ma le atinaʻeina o saienisi ma tekinolosi, o le faʻaogaina o tekinolosi faʻamalama malamalama ua atiaʻe mai le uluai laupapa lolomi ma photoresist i le faʻamalama faʻamalama ufiufi, vaitusi ma faʻapipiʻi.O le fanua talosaga ua faʻalauteleina ma fausia ai se pisinisi fou.
O mea e masani ona fa'agata ai le UV o fa'alavalava UV, vaitusi UV ma fa'apipi'i UV.O lo latou pito sili ona tele o lo latou vave fa'amaloloina, masani i le va o ni nai sekone ma le sefulu sekone.Ole vave e mafai ona faʻamalolo ile 0.05 ~ 0.1s.O le fa'amago ma le fa'amalologa sili ona vave i totonu o fa'alavalava eseese, vaitusi ma mea fa'apipi'i i le taimi nei.
UV fa'amalolo o le UV fa'amalolo.UV o le faapuupuuga faaPeretania o le UV.Fa'amalologa e fa'atatau i le fa'agasologa o le suia o mea mai mole mole maualalo i polymers.O le fa'amaloloina o le UV e masani lava ona fa'atatau i tulaga fa'amalolo po'o mana'oga o pa'u (vali), vaitusi, fa'apipi'i (kelu) po'o isi fa'amaufa'ailoga ipu e mana'omia ona fa'amālōlōina e le UV, e ese mai i le fa'avevelaina o le fa'amafanafanaina, so'o fa'apipi'i (solution agent) fa'amalologa, fa'alenatura. faamalolo, ma isi [1].
O vaega autu o oloa faʻamaʻi mama e aofia ai oligomers, diluents malosi, photoinitiators, additives ma isi.Oligomer o le tino autu o oloa faʻamalolo UV, ma o lona faʻatinoga e faʻamoemoeina ai le faʻatinoga autu o mea faʻamalolo.O le mea lea, o le filifilia ma le mamanu o le oligomer e le masalomia o se fesoʻotaʻiga taua i le faʻatulagaina o oloa faʻamalolo UV.
O le mea e tutusa ai nei oligomers o lo'o i ai uma i latou "Unsaturated double bond resins e fa'avasegaina e tusa ai ma le fua o le tali o le polymerization radical free: acryloyloxy > Methacryloyloxy > vinyl > allyl.O le mea lea, o le oligomers o loʻo faʻaaogaina i le faʻamaloloina o le malamalama saoloto e masani lava o ituaiga uma o resini acrylic, e pei o le epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, acrylate resin poʻo le vinyl resin, ma le epoxy acrylate o le sili ona faʻaaogaina Acrylic resin, polyurethane. fa'amea fa'akomepi ma le fa'amea fa'ameamea.O nei resini e tolu o loʻo faʻaalia puupuu i lalo.
O le epoxy acrylate o le oligomer e sili ona fa'aaogaina ma fa'aaogaina.E saunia mai le epoxy resin ma (meth) acrylate.Epoxy acrylate e mafai ona vaevaeina i bisphenol A epoxy acrylate, phenolic epoxy acrylate, suia epoxy acrylate ma epoxidated acrylate e tusa ai ma le ituaiga fausaga.Bisphenol O le epoxy acrylate e sili ona fa'aaogaina.Bisphenol O le epoxy acrylate o se tasi o oligomers e sili ona vave faʻamalolo moli.O le ata faʻamalolo e maualuga le maʻaʻa, maualuga iila, sili atu vailaʻau faʻamaʻi, vevela lelei ma mea eletise.E le gata i lea, o le bisphenol A okesene exchange acrylate o lo'o i ai se fua fa'atatau faigofie ma tau maualalo.O le mea lea, e masani ona faʻaaogaina e pei o le resini autu o pepa faʻamalama malamalama, fafie, palasitika ma uʻamea faʻapipiʻi, faʻapea foʻi ma le resini autu ole vaitusi faʻamaʻi malamalama ma faʻapipiʻi faʻamaʻi.
Polyurethane acrylate
O le polyurethane acrylate (PUA) o se isi moli taua e faʻamalolo ai oligomer.O loʻo faʻapipiʻiina e ala i le lua-laasaga faʻaalia o le polyisocyanate, umi-chain diol ma le hydroxyl acrylate.Ona o le tele o fausaga o polyisocyanates ma filifili umi-diols, oligomers ma meatotino seti ua tuufaatasia e ala i mamanu mole.O le mea lea, o latou oligomers ma le tele o ituaiga o oloa i le taimi nei, ma o loʻo faʻaaogaina lautele i faʻamaʻi mama faʻafefe, inks ma adhesives.
Polyester Acrylate
Polyester acrylate (PEA) o se oligomer masani.E saunia e ala i le acrylate o le maualalo mole mole mamafa polyester glycol.Polyester acrylate o loʻo faʻaalia i le tau maualalo ma le maualalo o le viscosity.Ona o lona viscosity maualalo, polyester acrylate e mafai ona faʻaaogaina e fai ma oligomer ma faʻamalosi malosi.E le gata i lea, o polyester acrylates e tele lava ina maualalo le manogi, maualalo le ita, fetuutuunai lelei ma pigmenti susu, ma e talafeagai mo vali lanu ma vaitusi.Ina ia faʻaleleia le maualuga o le faʻamalolo, e mafai ona saunia le polyester acrylate multifunctional;Amine suia polyester acrylate e le gata e mafai ona faaitiitia le aafiaga o le okesene polymerization inhibition ma faaleleia le fua faatatau faamalolo, ae faaleleia foi le pipii, susulu ma ofuina tetee.
O lo'o fa'agaoioi e masani ona i ai vaega fa'agaoioiga, e mafai ona fa'amavae ma fa'afefe oligomers, ma faia se sao taua i le fa'amama fa'amalama ma meatotino ata.E tusa ai ma le aofa'i o vaega fa'afoliga o lo'o i ai, o mea fa'apipi'i gaogao masani e aofia ai le isodecyl acrylate, lauryl acrylate, hydroxyethyl methacrylate, glycidyl methacrylate, ma isi;Bifunctional diluents malosi e aofia ai polyethylene glycol diacrylate faasologa, dipropylene glycol diacrylate, neopentyl glycol diacrylate, ma isi;Fa'ato'a fa'agaoioiga fa'aleaogaina e pei ole trimethylolpropane triacrylate, ma isi.
Initiator ei ai se aafiaga taua i le fua faatatau curing o oloa UV curing.I oloa faʻamalolo UV, o le aofaʻi faʻaopoopoga o le photoinitiator e masani lava 3% ~ 5%.E le gata i lea, o pigments ma mea faʻapipiʻi faʻapipiʻi e iai foi se aafiaga taua i mea mulimuli o oloa faʻamalolo UV.
