Theknoloji ea kalafo ea UV ke mofuta oa ts'ireletso ea tikoloho e sebetsang hantle haholo, e bolokang matla le ea boleng bo holimo.E tsejoa e le theknoloji e ncha ea indasteri e tala lekholong la bo21 la lilemo.Ka nts'etsopele ea mahlale le theknoloji, ts'ebeliso ea theknoloji ea pholiso ea UV e tsoetse pele ho tloha libotong tsa khale tse hatisitsoeng le li-photoresists ho isa ho lijalo tsa UV, li-inks le likhomaretsi.Sebaka sa kopo se ntse se hola, se theha indasteri e ncha.
Lihlahisoa tse folisang tsa UV hangata li arotsoe ka likhahla tsa UV, li-inks tsa UV le likhomaretsi tsa UV.Tšobotsi ea bona e kholo ke hore ba na le sekhahla sa ho folisa ka potlako, hangata pakeng tsa metsotsoana e seng mekae le metsotsoana e mashome, 'me e potlakileng e ka phekoloa ka hare ho 0.05 ~ 0.1s.Ke tsona tse omisang le ho folisa ka potlako har'a liphahlo tse fapaneng, li-inks le likhomaretsi hajoale.
Pholiso ea UV e bolela ho phekola UV.UV ke khutsufatso ea Senyesemane ea UV.Ho phekola ho bolela mokhoa oo lintho li fetohang ho tloha ho limolek'hule tse tlaase ho ea ho li-polymers.Pheko ea UV ka kakaretso e bolela maemo a pheko kapa litlhoko tsa lipente (lipente), li-inks, likhomaretsi (likhomaretsi) kapa li-sealant tse ling tse hlokang pheko ea UV, tse fapaneng le pheko ea ho futhumatsa, ho folisa ka likhomaretsi (li-agent), pheko ea tlhaho, jj.

Likarolo tsa mantlha tsa lihlahisoa tsa pholiso ea UV li kenyelletsa li-oligomers, li-diluents tse sebetsang, li-photoinitiators, li-additives joalo-joalo.Oligomer ke 'mele o ka sehloohong oa lihlahisoa tse phekolang tsa UV,' me ts'ebetso ea eona e supa ts'ebetso ea mantlha ea lisebelisoa tse folisitsoeng.Ka hona, khetho le moralo oa oligomer ntle le pelaelo ke sehokelo sa bohlokoa ho thehoeng ha lihlahisoa tsa pholiso ea UV.
Seo li-oligomers tsena li tšoanang ka sona ke hore kaofela ha tsona li na le Unsaturated double bond resin li behiloe ka sekhahla sa karabelo ea free radical polymerization: acryloyloxy > methacrylyloxy > vinyl > allyl. joalo ka epoxy acrylate, polyurethane acrylate, polyester acrylate, polyether acrylate, acrylate resin kapa vinyl resin, 'me tse sebelisoang haholo ke epoxy acrylate resin, polyurethane acrylate resin le polyester acrylic resin.Li-resin tsena tse tharo li hlahisoa ka bokhutšoanyane ka tlase.
Epoxy acrylate
Epoxy acrylic acid boleng ke eona e sebelisoang ka ho fetesisa ebile ke palo e kholo ka ho fetisisa ea oligomer e phekolang ea UV hajoale.E hlophisitsoe ho tsoa ho epoxy resin le (meth) acrylate.Epoxy acrylates e ka aroloa ka bisphenol A epoxy acrylates, phenolic epoxy acrylates, modified epoxy acrylates le epoxidized acrylates ho ea ka mefuta ea tsona ea sebopeho, le bisphenol A epoxy acrylates ke tsona tse sebelisoang ka ho fetisisa.
Bisphenol A epoxy acrylate ke e 'ngoe ea li-oligomers tse nang le sekhahla se potlakileng sa ho folisa khanya.Filimi e phekotsoeng e na le boima bo phahameng, bokhabane bo phahameng, khanyetso e ntle ea lik'hemik'hale, ho hanyetsa mocheso o motle le thepa ea motlakase.Ntle le moo, bisphenol A oxygen exchange acrylate e na le foromo e bonolo ea thepa e tala le theko e tlase.Ka hona, hangata e sebelisoa e le resin ea mantlha bakeng sa pampiri e folisang leseli, patsi, polasetiki le litšepe tsa tšepe, hape e le resin ea mantlha bakeng sa enke e folisang leseli le sekhomaretsi se bobebe.
Polyurethane acrylate
Polyurethane acrylate (PUA) ke oligomer e 'ngoe ea bohlokoa e phekolehang ka UV.E entsoe ka karabelo ea mehato e 'meli ea polyisocyanate, diol ea ketane e telele le hydroxyl acrylate.Ka lebaka la meaho e mengata ea li-polyisocyanate le li-diol tsa ketane e telele, li-oligomers tse nang le thepa e behiloeng li entsoe ka moralo oa limolek'hule.Ka hona, ke li-oligomers tse nang le lihlahisoa tse ngata ka ho fetisisa hona joale, 'me li sebelisoa haholo ho li-coating tsa UV, li-inks le li-adhesives.
Polyester Acrylate
Polyester acrylate (PEA) le eona ke oligomer e tloaelehileng, e lokiselitsoeng ho tloha ho polyester glycol e tlaase ea molek'hule ka acrylate.Polyester acrylate e tšoauoa ka theko e tlase le viscosity e tlase.Ka lebaka la viscosity ea eona e tlase, polyester acrylate e ka sebelisoa e le oligomer le diluent e sebetsang.Ho phaella moo, li-acrylates tse ngata tsa polyester li na le monko o fokolang, ho halefa ho fokolang, ho feto-fetoha ha maemo le ho nosetsa ha pigment, 'me li loketse lipente tsa mebala le li-inks.E le ho ntlafatsa tekanyo e phahameng ea ho folisa, acrylate ea polyester e sebetsang ka bongata e ka lokisoa;Amine e fetotsoeng polyester acrylate e ke ke ea fokotsa feela tšusumetso ea ho thibela polymerization ea oksijene, ho ntlafatsa lebelo la ho folisa, empa hape ho ntlafatsa ho khomarela, ho benya le ho apara ho hanyetsa.
Li-diluent tse sebetsang hangata li na le lihlopha tse sebetsang, tse ka qhibilihang le ho hlapolla li-oligomers, 'me li bapala karolo ea bohlokoa ts'ebetsong ea ho phekola UV le thepa ea filimi.Ho ea ka palo ea lihlopha tse sebetsang ka matla, li-diluent tse tloaelehileng tse sebetsang ka monofunctional li kenyelletsa isodecyl acrylate, lauryl acrylate, hydroxyethyl methacrylate, glycidyl methacrylate, joalo-joalo;Li-diluent tse sebetsang ka makhetlo a mabeli li kenyelletsa letoto la polyethylene glycol diacrylate, dipropylene glycol diacrylate, neopenyl glycol diacrylate, joalo-joalo;Li-diluent tse sebetsang ka bongata tse kang trimethylolpropane triacrylate, joalo-joalo [2].
