O le fa'amaloloina o le Ultraviolet (UV) o se ituaiga fou o le puipuiga o le si'osi'omaga.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'agata 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 ufiufi, ma o le vaega vai o le ufiufi.O le faʻatinoga o ata tifaga, faʻaogaina ma isi mea faʻapitoa o le faʻapipiʻiina e faʻalagolago lava i mea e fai ai ata.O mea e fai ata tifaga o le ufiufi UV o se oligomer.O lona fa'atinoga e fa'atatau tonu i le fa'atinoga o le fa'aogaina, fua faatatau fa'amama mama, fa'atinoga o ata ma isi mea fa'apitoa o le fa'alavalava a'o le'i fa'amaloloina.
UV coatings e masani lava free radical light curing system, o lea la o oligomers o loʻo faʻaaogaina o resini acrylic eseese.Cationic UV coating oligomers o epoxy resin ma vinyl eter compounds.
2. fa'afefete malosi
O le fa'afefete malosi o se isi vaega taua o le ufiufi UV.E mafai ona faʻafefe ma faʻaitiitia le viscosity, ma e mafai foi ona fetuunai le faʻatinoga o ata tifaga 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 faʻatulagaga moni, mono -, Bi -, ma acrylates tele-galuega o le a faʻaaogaina faʻatasi e faʻapipiʻi ai a latou meatotino ma maua ai se aafiaga 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 le faʻapipiʻiina o le UV e le o le ferrous, e tatau ona avea le photoinitiators itx, 907, 369, TPO, 819, ma isi. O nisi taimi, ina ia faʻaitiitia ai le faʻaogaina o le polymerization o le okesene ma faʻaleleia le fua o le faʻamalolo o le UV, o se vaega itiiti o le amine galue e masani ona faʻaopoopo i le UV. ufiufi.
4. fa'aopoopo
O mea fa'aopoopo o vaega fesoasoani ia o fa'alavalava UV.O le matafaioi o mea faʻaopoopo o le faʻaleleia lea o le gaioiga o le gaosiga, faʻaogaina o le teuina ma le faʻaogaina o le faʻaogaina o le faʻapipiʻiina, faʻaleleia le faʻatinoina o ata 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.
