Fa'apipi'i o le UV Curable Waterborne Polyurethane Acrylate Coatings Fa'aaliga Ata

Fa'apipi'i o Uvi fa'agata vai fa'a'ele'ele polyurethane fa'apipi'i

Fa'amatalaga Puupuu:

Uv-wpua coating e aofia ai le oligomer, photoinitiator, active diluent, etc. Oligomer o le vaega sili ona taua i le uv-wpua coating.O lona fausaga e fuafua ai mea taua o le UV curing film, e pei o le maaa, fetuutuunai, ofuina teteʻe, vai teteʻe ma corrosion teteʻe.Photoinitiator o se vaega taua o le faiga faʻamalolo UV, lea e taʻalo ai se sao taua i le faʻaogaina o le faʻagasologa o le faʻamaloloina o le UV ma e aʻafia ai foi le faʻatinoga mulimuli o ata faʻamalolo.Uv-wpua coating e fa'aaogaina le vai e pei o le fa'afefe malosi, lea e matua fa'aitiitia ai le fa'aogaina o so'o so'o.

Fa'atasiga o le Waterborne Polyurethane Acrylate

O le oligomer i le uv-wpua coating o le wpua, o le vaega autu o le ufiufi.O le Wpua e masani lava ona fausia e ala ile tali ole polyisocyanate, diol ma le hydroxyl acrylate.Isocyanates e aofia ai isocyanates aromatic, isocyanates aliphatic ma isocyanates alicyclic, lea e aʻafia ai le faʻamalosi, teteʻe o le tau ma le samasama o le wpua.O Diols e masani lava ona aofia ai polyether diols ma polyester diols, lea e aʻafia ai le malosi faʻamalosi, vaivai, vevela vevela ma le hydrolysis tetee o le wpua.
O le - NCO vaega i le polyisocyanate e tali atu i le vaega hydroxyl o le diol e fausia ai se oligomer ma vaega isocyanate i pito uma e lua.2. 2,2-dihydroxymethylpropionic acid (DMPA) o loʻo faʻaaogaina e pei o le diol e faʻafeiloaʻi ai vaega hydrophilic i totonu o le oligomer, ma faʻaopoopoina le 1,4-butanediol (BDO) mo le faʻalauteleina o filifili;3. Hydroxyethyl acrylate (HEA) sa fa'aogaina e fa'ailoa ai ata fa'atupu vaega o lo'o iai fa'amau fa'alua e le'i tumu mo le fa'amaloloina o le UV.A maeʻa le tali e tolu-laasaga, faʻaopoopo le triethanolamine (teoa) mo le faʻaleagaina o le tali, ma mulimuli ane faʻaopopo le vai e faʻafefe ai i le lotion.
O isi tagata atamamai ua faʻapipiʻiina le uv-wpua ma le faʻatinoga sili ona lelei e ala i le faʻaogaina o mea faʻapipiʻi e pei ole Polyhexylene glycol, isophorone diisocyanate, PETA, ma le dimethylbutyric acid (DMBA).E tolu ituaiga o wpua na fa'apipi'iina mai le polyacrylate saunia ma le vaega carboxyl i filifili itu, polyether polyol, isophorone diisocyanate ma le hydroxyethyl acrylate.A maeʻa suʻesuʻega faʻapitoa o suʻega faʻaletino ma suʻega faʻaoga, ua manatu e sili atu le lelei o le faʻatinoga o le polyether wpua.Faʻaaogaina toluene diisocyanate, polyhexanediol, 2,2-dihydroxymethylpropionic acid ma hydroxyethyl methacrylate e pei o mea mata, na faʻapipiʻiina muamua le prepolymer, ona faʻaopoopoina lea o le triethylamine e avea ma sui faʻafefe, ma faʻaaogaina le vai e faʻasalalau filifili i le vai e fausia ai le lotion wpua mautu.
