Lisebelisoa tse ka sehloohong

Likarolo tse ka sehloohong tsa enke ea UV li kenyelletsa pigment, oligomer, monomer (diluent e sebetsang), photoinitiator le lisebelisoa tse fapaneng.Har'a bona, resin le diluent e sebetsang e bapala karolo ea ho lokisa pigment le ho fana ka thepa ea ho etsa filimi;Li-pigments li fana ka 'mala o leka-lekaneng oa enke le matla a sekoahelo ho substrate;Photoinitiator e hlokahala hore e khone ho monya lifoto tlas'a tšitiso ea li-pigments ho qala polymerization.

1, Metsoako ea Monomolecular (diluent e sebetsang)

Ona ke motsoako o bonolo o nang le boima ba limolek'hule tse nyane, o ka fokotsa viscosity, oa bapala karolo ea ho qhalakanya, o ka qhala mebala, oa qhibilihisa resin, oa tseba lebelo la ho folisa le ho khomarela ha enke, 'me oa kenya letsoho ho resin ea UV e phekolang crosslinking reaction.

2, Additives

Ho akarelletsa le li-pigments, lubricants, thickening agent, filler, solidifying agent, joalo-joalo E ama gloss ea enke, viscosity, bonolo, 'mala, botenya ba filimi, lebelo la ho folisa, ho tšoaneleha ha khatiso le thepa e' ngoe.

3, Resin e tiileng e bobebe ke lisebelisoa tse hokelang enke tsa UV

Lebelo la ho folisa enke ea UV, gloss, adhesion, ho hanyetsa likhohlano le thepa e 'ngoe, enke e fapaneng e na le mefuta e fapaneng ea resin e tsoakiloeng.

4, Light Initiator

Light initiator e le borokho pakeng tsa karabelo ea lik'hemik'hale, ke mofuta oa khanya ea khanya e fetohang haholo, ka mor'a hore e monye photon e hlahisa li-radicals tsa mahala, matla a ho fetisetsa matla ho li-polymer tse ling tsa photosensitive, a hlahisa ketane, thepa e le 'ngoe ea molek'hule, addititive, light solid resin. hammoho, etsa hore enke folisa karabelo, 'me ka mor'a ho lokolloa ha matla ka boeona ha e amehe ka karabelo crosslinking.

Motheo oa ho Tiisa

Tlas'a mahlaseli a leseli la ultraviolet, ho kenngoa ha matla ho hlahisa li-radicals tsa mahala, ts'ebetso ea mahala ea radical ka lebelo le phahameng, ho thulana ho etsahala ka resin le motsoako o le mong oa molek'hule, ho fetisetsa matla ho resin le metsoako ea molek'hule e le 'ngoe, resin le motsoako o le mong oa molek'hule. ka mor'a ho monya matla a matla a nang le unsaturated double bond atoms polymerized monomer polymer le radicals, e leng, resin le metsoako ea molek'hule e le 'ngoe, Ba bula bond e habeli' me ba qala karabelo ea ho kopanya, pheko e kopanyang, moo photoinitiator e lahleheloang ke matla le ho khutla. ho isa boemong ba yona ba pele.

Lintlha Tse Amang

Enke e folisang ea UV e tlameha ho ba le leseli la UV ho folisa, ho seng joalo e ke ke ea sebelisoa.Tšebelisong ea enke ea UV, bothata ba pele ba ho khomarela ke hore enke ea UV ha e na phekolo e tebileng.Mabapi le lisebelisoa tse tiileng tse bobebe, lebaka e ka 'na ea e-ba ho hlōleha ha lisebelisoa tsa phekolo ea UV, ke hore, bolelele ba maqhubu a lisebelisoa tsa ho phekola UV ha bo lumellane le enke e tiileng ea leseli la UV, kapa matla a tiileng a khanyang ha a lekana, kapa lebelo le tiileng le khanyang ha lea lekana. loketseng.

1, enke e bobebe e tiileng ea UV e bobebe e tiileng ea spectral sensitivity range bakeng sa wavelength pakeng tsa 180-420NM.

2, matla a lebone la UV a tlameha ho fihlela litlhoko tsa theknoloji tsa ho folisa enke.

3, lebelo la khatiso le potlakile haholo le boetse le ama lebelo la ho folisa la enke.

4, tšusumetso ea botenya ba enke, enke e teteaneng haholo e tla ama phello ea pholiso, lintlha tsohle tse amang botenya ba filimi ea khatiso li tla ama phello ea pholiso.

5, phello ea boemo ba leholimo: mocheso o phahameng, viscosity ea enke ea UV e ba tlase, ka mor'a hore e hatisoe, ho bonolo ho hlahisa ketsahalo ea peista version.Mocheso o tlase, viscosity e phahameng, ama thixotropy ea enke, mocheso oa workshop e ke ke ea e-ba holimo haholo, mariha sebakeng sa polokelo ea thepa ea moea, e lokela ho kenngoa mocheso oa kamore, 'me e loketseng e fokotsa lebelo la ho folisa.

6, tšusumetso ea pigment ho enke ea UV: ka lebaka la mebala e fapaneng ea ho monya leseli, ponts'o le litaba tsa pigment ka kakaretso, bosoeu, botsho, boputsoa bo thata ho phekola, bofubelu, bosehla, oli e bobebe, oli e bonaletsang ho bonolo ho e phekola. .
