Kuumbwa kweUV offset inki
2024-05-13
UV offset printing inki zvinhu zvine hunyanzvi zvekudhinda zvakagadzirirwa kukurumidza ultraviolet (UV) mwenje kurapa. Kuumbwa kwavo kwakagadzirwa zvine hungwaru kuti ive nechokwadi chemhando yepamusoro yekudhinda uye nekuomesa nekuomesa zvinhu. Izvo zvakakosha zvikamu zveingi idzi zvinogona kutsanangurwa sezvizvi:
- UV-Anorapika Resins: Pamwoyo weingi idzi pane UV-sensitive resins, senge acrylates, ethylene esters, uye epoxy resins, ayo anokurumidza kuyambuka uye kurapa pasi pemwaranzi yeUV.
- Monomers: Inoshandiswa pamwe chete neiyo UV-inorapika resins, monomers senge acrylic uye methacrylic acid esters inofambisa maitiro epolymerization kana yaitwa neUV mwenje, ichikurumidza kurapa.
- Photoinitiators: Aya makomisheni anotora UV simba uye anorishandura kuita kemikari simba, zvichikonzera kuita kwepolymerization mukati meinki. Iwo anosanganisira vekutanga ekutanga uye vabatsiri vamiririri.
- Pigment uye Pigment Dispersants: Pigment inopa ruvara uye yekuona maitiro, nepo madhirigi achivimbisa kunyangwe kupararira kwe pigment kuti ienderane ruvara uye kudhinda mhando.
- Additives: Kusanganisira antioxidants, UV stabilizers, rheology modifiers, hardener, pakati pezvimwe, izvi zvinosanganisirwa kuwedzera inki kuita uye kugadzikana. Diluents inoshandiswawo kugadzirisa viscosity uye kuyerera, kugovera kune zvakasiyana-siyana kudhinda zvinodiwa.
- Zvimwe Zvishongedzo: Zvichienderana nemugadziri uye nezvinodiwa zvekushandisa, ingi dzinogona kusanganisira zvimwe zvinhu senge maajenti ekuburitsa uye anti-settling agents. Magadzirirwo anochinjika kuti asangane nemamwe maitiro ekuita.
Muchidimbu, UV offset kudhinda ingi, nekukurumidza kurapa kwayo, abrasion kuramba, kusimba kwemakemikari, uye yakasarudzika mhando yekudhinda, tsvaga yakafararira muindasitiri yekudhinda, kunyanya mumhando yepamusoro uye yepamusoro-soro mabasa ekudhinda.
