UV kudhinda inzira yakasarudzika yekudhinda kwedhijitarikushandisa ultraviolet (UV) mwenje kuomesa kana kurapa inki, zvinonamira kana machira paanenge angorova bepa, kana aluminium, foam board kana acrylic - kutaura zvazviri, chero inokodzera muprinta, nzira yacho inogona kushandiswa dhinda pane chero chinhu.
Iyo nzira yekurapa UV - iyo photochemical process yekuomesa - yakatanga kuunzwa senzira yekukurumidza kuomesa gel zvipikiri polishes anoshandiswa mu manicure, asi ichangobva kugamuchirwa neindasitiri yekudhinda iyo inoshandiswa kudhinda pane chero chinhu kubva kumasaini nemabhurocha. kumabhodhoro edoro.Nzira yacho yakafanana nekudhinda kwechinyakare, musiyano chete ingi dzinoshandiswa uye nzira yekuomesa - uye zvigadzirwa zvepamusoro zvinogadzirwa.
Mukudhinda kwechinyakare, inki dzesolvent dzinoshandiswa;izvi zvinogona kubuda uye kuburitsa volatile organic compounds (VOCs) izvo zvinokuvadza kune zvakatipoteredza.Iyo nzira inogadzirawo - uye inoshandisa - kupisa uye kunhuhwirira kunoperekedza.Uyezve, zvinoda mamwe mapoda ekupfapfaidza kubatsira neingi yekubvisa uye kuomesa, izvo zvinogona kutora mazuva akati wandei.Ingi dzinopinzwa mukati medhindiro, saka mavara anogona kuita seakagezwa uye kupera simba.Maitiro ekudhinda anogumira kunyanya kumapepa nemakadhi masvikiro, saka haagone kushandiswa pazvinhu zvakaita sepurasitiki, girazi, simbi, foil kana acrylic seUV kudhinda.
Mukudhinda kweUV, mercury / quartz kana mwenje ye LED inoshandiswa pakurapa panzvimbo yekupisa;iyo yakanyatsogadzirwa yakakwirira-yakasimba UV mwenje inoteedzera sezvo yakakosha inki inogoverwa padhindiro svikiro, ichiomesa kana yangoiswa.Nekuti iyo ingi inoshanduka kubva pakasimba kana kunamira kuenda kumvura nekukasira, hapana mukana wekuti inyunguduke uye saka hapana maVOCs, utsi hune muchetura kana ozone inoburitswa, zvichiita kuti tekinoroji ienderane nemhoteredzo ingangoita zero kabhoni tsoka.
Iyo inki, inonamira kana yekunamira ine musanganiswa wemvura monomers, oligomers - mapolymers ane mashoma anodzokorora mayunitsi - uye mafotoinitiators.Munguva yekurapa, yakakwira-yakasimba mwenje mu ultraviolet chikamu che spectrum, ine wavelength pakati pe 200 ne 400 nm, inotorwa ne photoinitiator iyo inosangana nemakemikari reaction - kemikari cross linking - uye inokonzera iyo inki, kupeta kana kunamira kuomesa pakarepo.
Zviri nyore kuona kuti nei kudhinda kweUV kwabata mvura yechinyakare uye matekiniki-anopisa anoomesa matekiniki uye nei zvichitarisirwa kuramba zvichikura mukuzivikanwa.Haisi chete iyo nzira inomhanyisa kugadzirwa - zvichireva kuti zvakawanda zvinoitwa munguva shoma - mitengo yekurambwa inoderedzwa sezvo mhando iri pamusoro.Madonhwe akanyorova einki anobviswa, saka hapana kukwesha kana kuputika, uye sezvo kuomeswa kunenge kwakaringana, hapana evaporation uye saka hapana kurasikirwa kwekuputira ukobvu kana huwandu.Ruzivo rwakanaka runogoneka, uye mavara akapinza uye akajeka zvakanyanya sezvo pasina kunyura kune inodhinda svikiro: kusarudza UV kudhinda pamusoro pechinyakare nzira dzekudhinda kunogona kuve mutsauko pakati pekugadzira chigadzirwa cheumbozha, uye chimwe chinhu chinonzwa kushoma.
Ingi zvakare dzakanatsiridza zvimiro zvemuviri, yakagadziridzwa gloss kupera, zvirinani kukwenya, makemikari, solvent uye kuomarara kuramba, elasticity iri nani uye chigadzirwa chekupedzisa zvakare chinobatsira kubva mukusimba kwesimba.Iwo zvakare anogara akasimba uye anoshingirira mamiriro ekunze, uye anopa kuwedzera kuramba kupera kuchiita kuti ive yakanakira zviratidzo zvekunze.Nzira yacho inowedzerawo mari - zvigadzirwa zvakawanda zvinogona kudhindwa munguva shoma, pahutano huri nani uye nekuramba kushoma.Kushaikwa kweVOCs inoburitswa kunoreva kuti kune kushomeka kukuvadza kune zvakatipoteredza uye tsika yacho inogadzikana.
