Uv curing (UV) coating ose ituaiga fou ole si'osi'omaga fa'alelei.O lona fua fa'amago e vave tele.E mafai ona faʻamaloloina e le malamalama UV i ni nai sekone, ma e maualuga le gaosiga o le gaosiga.
UV fa'amalolo fa'alavalava e tele lava ina aofia ai oligomers, diluents malosi, photoinitiators ma additives.
1. Oligomer
O mea e fai ata tifaga o le vaega autu lea o le faʻapipiʻiina, o le vaega vai o le ufiufi.O le faʻatinoga o ata, faʻatinoga o le fausiaina ma isi mea faʻapitoa o le faʻapipiʻiina e faʻalagolago lava i mea e fai ai ata.O le mea e fai ata tifaga o le ufiufi o le UV o le oligomer, ma o lona faʻatinoga e fuafua ai le faʻatinoga o le fausiaina ma le fua o le faʻamalama o le paʻu aʻo leʻi faʻamaloloina, o le ata tifaga pe a uma ona faʻamalolo ma isi mea faʻapitoa.
UV coatings e masani lava free radical faʻamaloloina faiga, o lea o le oligomers faʻaaogaina o ituaiga uma o resins acrylic.Cationic UV coating oligomers o epoxy resin ma vinyl eter compounds.
2. Active diluent
O le fa'afefete malosi o se isi vaega taua o le ufiufi UV.E mafai ona faʻafefe ma faʻaitiitia le viscosity, ma e iai foʻi le meatotino e faʻafetaui ai le ata faʻamalolo.O monomers galue acrylate e maualuga le gaioiga ma le maualalo o le volatility, o lea e masani ona faʻaaogaina i UV coatings.E masani ona faʻaaogaina esters akrilik e fai ma faʻamaʻi faʻamalosi mo paʻu UV.I le fua faʻatatau, mono -, bifunctional ma multi-functional acrylates o le a faʻaaogaina faʻatasi e faʻapipiʻi ai a latou meatotino ma ausia le faʻamoemoega lelei atoatoa.
3. Photoinitiator
Photoinitiator o se faʻalavelave faʻapitoa i faʻamalama UV.O se vaega taua o le UV coatings ma fuafua le fua faatatau fa'amaloloina o UV o coatings UV.
Mo le lanu varnish UV coatings, 1173, 184, 651 ma bp / amine maualuga e masani ona faʻaaogaina e fai ma photoinitiators.184 fa'atasi ai ma le maualuga o le gaioiga, maualalo le manogi ma le samasama tete'e, o le photoinitiator e sili ona lelei mo le lanu samasama fa'afefe UV coatings.Ina ia faʻaleleia le fua o le faʻamaloloina o le malamalama, e masani ona faʻaaogaina faʻatasi ma le TPO.
Mo lanu UV coatings, photoinitiators e tatau ona itx, 907, 369, TPO, 819, ma isi O nisi taimi, ina ia faʻaitiitia le faʻasaina o le polymerization o le okesene ma faʻaleleia le fua o le faʻamalolo o le UV, e masani ona faʻaopoopoina se vaega itiiti o le amine reactive i le ufiufi UV.
4. Fa'aopoopo
O mea fa'aopoopo o vaega fesoasoani ia o fa'alavalava UV.O le matafaioi a mea faʻaopoopo o le faʻaleleia lea o le gaioiga o gaioiga, faʻaogaina o le teuina ma le fausiaina o le faʻaogaina o le faʻapipiʻiina, faʻaleleia le faʻatinoga o ata tifaga ma faʻaeʻeina le ata i ni galuega faʻapitoa.O mea fa'aopoopo e masani ona fa'aoga mo fa'alavalava UV e aofia ai le fa'amama, fa'ameamea, fa'asusu fa'asusu, fa'auluulu fa'apipi'i, sui fa'amau, inhibitor polymerization, ma isi, lea e ta'alo ese'ese matafaioi i fa'alavalava UV.
