Kazhinji, kudhinda kweUV kunosanganisira mhando dzematekinoroji anotevera:
1. Midziyo yeChiedza cheUV
Izvi zvinosanganisira marambi, magirazi anodzora chiedza, masisitimu ekudzora simba, uye masisitimu ekudzora tembiricha (kutonhodza).
(1) Mwenje
Marambi eUV anonyanya kushandiswa ndiwo marambi emercury vapor, ane mercury mukati mechubhu. Mune zvimwe zviitiko, dzimwe simbi dzakadai segallium dzinowedzerwa kugadzirisa kubuda kwespectral.
Marambi esimbi-halide nemarambi equartz anoshandiswawo zvakanyanya, uye akawanda achiri kutengeswa kunze kwenyika.
Hurefu hwewavelength hunoburitswa nemarambi eUV anodzivirira hunofanira kunge huri pakati pe200–400 nm kuti hushande pakuporesa.
(2) Zvinoratidza
Basa guru re reflector nderekudzorera mwaranzi yeUV kumashure kune substrate kuti iwedzere kushanda zvakanaka kwemurazvo (UV Tech Publications, 1991). Rimwe basa rakakosha nderekubatsira kuchengetedza tembiricha yakakodzera yekushanda kwemwenje.
Magirazi anowanzo gadzirwa nearuminiyamu, uye girazi rinowanzo fanirwa kusvika pa90%.
Kune magadzirirwo maviri ekutanga e reflector: focused (elliptical) uye non-focused (parabolic), pamwe nemamwe magadzirirwo akagadzirwa nevagadziri.
(3) Masisitimu Ekudzora Simba
Masisitimu aya anoita kuti UV irambe yakagadzikana, ichichengetedza kushanda zvakanaka uye kugadzikana uku ichichinja zvichienderana nekumhanya kwakasiyana kwekudhinda. Mamwe masisitimu anodzorwa nemagetsi, nepo mamwe achishandisa microcomputer control.
2. Masisitimu Ekutonhodza
Nekuti marambi eUV haangoburitse mwaranzi yeUV chete asiwo kupisa kwe infrared (IR), michina inoshanda pakupisa kwakanyanya (semuenzaniso, tembiricha yepamusoro yemarambi akavakirwa pa quartz inogona kusvika mazana akati wandei emadhigirii Celsius).
Kupisa kwakanyanya kunogona kupfupisa hupenyu hwemichina uye kunogona kukonzera kukura kana kushanduka kwesubstrate, zvichikonzera zvikanganiso zvekunyoresa panguva yekudhinda. Saka, masisitimu ekutonhodza akakosha zvikuru.
3. Sisitimu Yekupa Inki
Kana tichienzanisa neinki dzekare dze offset, inki dzeUV dzine viscosity yakakura uye kukweshana kukuru, uye dzinogona kukonzera kupera kwezvinhu zvemuchina zvakaita semagumbeze nemaroller.
Saka, panguva yekudhinda, ingi iri muchitubu inofanira kugara ichizungunuswa, uye maroller nemagumbeze ari muhurongwa hweinki anofanira kunge ari zvinhu zvakagadzirirwa kudhindwa kweUV.
Kuti inki irambe yakasimba uye kudzivirira kuchinja kwekusimba kwekupisa, masisitimu ekudzora kupisa anotenderera akakoshawo.
4. Kupisa uye Masisitimu Ekuburitsa Utsi
Masisitimu aya anobvisa kupisa kwakanyanya uye ozone inogadzirwa panguva yekugadzirwa kweink polymerization uye kuporesa.
Kazhinji dzine mota inoburitsa utsi uye sisitimu yekufambisa madhiraivha.
[Kugadzirwa kweOzone kunonyanya kusanganiswa nema UV wavelengths ari pasi pe ~240 nm; masisitimu mazhinji emazuva ano anoderedza ozone kuburikidza nemidziyo yakasefetwa kana LED.]
5. Inki dzekudhinda
Hunhu hweinki ndicho chinhu chinonyanya kukosha chinokanganisa mhedzisiro yekudhinda kweUV. Pamusoro pekukanganisa kuumbwa kwemavara uye gamut, kugona kudhindwa kweinki kunosarudza zvakananga kunamira, simba, uye kuramba kukwesha kwekudhinda kwekupedzisira.
Hunhu hwema photoinitiators nema monomers hwakakosha pakushanda.
Kuti ive nechokwadi chekuti inonamira zvakanaka, kana inki yeUV yakanyorova ikabatana nesubstrate, kusimba kwepamusoro pesubstrate (dynes/cm) kunofanira kunge kwakakwira kupfuura kweinki (Schilstra, 1997). Saka, kudzora kusimba kwepamusoro kweinki nesubstrate ndiyo tekinoroji huru mukudhinda kweUV.
6. Zvishandiso zvekuyera simba reUV
Nekuti zvinhu zvakaita sekukwegura kwemarambi, kushanduka kwesimba remagetsi, uye kuchinja kwekumhanya kwekudhinda zvinogona kukanganisa kupora, zvakakosha kutarisa nekuchengetedza simba reUV rakasimba. Saka, tekinoroji yekuyera simba reUV inoita basa rakakosha mukudhinda kweUV.
