Ndezvipi zvakanakira UV ink?

Iko kukurumidza kuvandudza kweindasitiri yekudhinda hakungodi hupamhi hwepamusoro uye kushanda zvakanaka, kuderedzwa kwemutengo, asiwo hakudi kusvibiswa kune zvakatipoteredza. UV inki inogona kudhindwa pane chero substrate, uye mhando yechigadzirwa chakadhindwa yakakwirira kune yakanyungudika yakavakirwa nemvura-based gravure printing inki. Iyo ine mabhenefiti akadai sediki dot kuwedzera, kupenya kwakanyanya, kupfeka kuramba uye kukukurwa kwemakemikari, hapana kusvibiswa, yakanaka dot kubereka maitiro uye kuvhara simba, uye mutengo wakaderera.

一、 Tsanangudzo yeIngi yeUV
UV ndiyo chidimbu chezwi reChirungu rekuti ultraviolet mwenje, UV yakarapwa uye yakaomeswa inki, yakapfupikiswa seUV inki. UV inki inonyanya ingi yemvura inogona kushandura kubva kumvura kuenda kune yakasimba pasi peimwe wavelength ye ultraviolet mwaranzi.
二、 Zvimiro zveUV inki
1. High cost performance ratio ye UV inki
UV inki haina kunyungudutsa kunonyungudutsa panguva yekudhinda, uye zvinhu zvakasimba zvinoramba zviri 100% pane substrate. Simba reruvara uye dot chimiro chinoramba chisina kuchinjika, uye yakatetepa inki layer ukobvu hunogona kuwana mibairo yakanaka yekudhinda. Kunyangwe ingi yeUV ichidhura kupfuura inki inonyungudutsa, 1kg UV inki inogona kudhinda 70 square metres yezvinhu zvakadhindwa, nepo 1kg solvent based inki inogona kungodhinda makumi matatu masikweya metres echinhu chakadhindwa.

2. UV inki inogona kuoma pakarepo uye ine yakakwirira kugadzirwa kwekubudirira
Ingi yeUV inogona kukurumidza kuomesa uye kuoma pasi pekuvhenekesa kwemwaranzi yeultraviolet, uye zvigadzirwa zvakadhindwa zvinogona kurongedzerwa nekukasika nekugadziriswa. Iyo yekumhanyisa yekugadzira ndeye 120-140m / min, uye inogona zvakare kuchengetedza 60% kusvika 80% yenzvimbo yekuchengetedza.
3. UV inki haisvibise zvakatipoteredza
Ingi yeUV haina zvinonyungudutsa zvinonyungudutsa, kureva 100% yekunyungudutsa isina formula, saka organic volatiles haibudiswe mumhepo panguva yekudhinda. Izvi zvinoenderana nemirairo yezvakatipoteredza uye zvakare inobvisa mari yekudzoreredza solvent.
4. UV inki yakachengeteka uye yakavimbika
UV inki igadziriro isingade mvura kana organic solvents. Kana ingi yaoma, firimu reinki rinenge rakasimba uye rinodzivirira kemikari, pasina kukuvadzwa kana kusvuura kunokonzerwa nekusangana nemakemikari. UV inki yakachengeteka kushandisa uye inogona kuchengetedza mari yeinishuwarenzi kune vashandisi. Yakakodzera kurongedza uye kudhinda zvinhu zvine hutsanana hunodiwa sechikafu, chinwiwa, uye zvinodhaka.
5. Yakanakisa UV inki kudhinda mhando
Munguva yekudhinda, UV inki inogona kuchengetedza yunifomu uye inowirirana ruvara, iyo inki layer yechigadzirwa chakadhindwa yakasimba, chikamu cheruvara nekubatanidza zvinhu zvinoramba zvisina kuchinjika, dot deformation idiki, uye inooma ipapo ipapo, ichibvumira kuti ipedze. multi-color overprinting.

6. UV inki ine yakagadzikana zvinhuUV inki inongoomesa pasi pe UV chiedza irradiation, uye nguva isina kuomesa pasi pemamiriro echisikigo inenge isingagumi. Iyi isiri kuomesa hunhu inovimbisa kuti inki viscosity inoramba yakagadzikana panguva yekushanda kwenguva refu yemuchina wekudhinda. Nekuda kwekushaikwa kweiyo organic matter volatilization, hapana chikonzero chekutarisa inki viscosity kuti ive nechokwadi chekutsikirira kwakatsetseka uye yakagadzikana kudhinda mhando. Naizvozvo, iyo inki inogona kuchengetwa kwehusiku mune inki hopper pasina kururamisa kwemavara.
