nkhani

M'munda wosindikiza, inki yomwe imagwiritsidwa ntchito posindikiza yawonetsanso zofunikira, inki ya UV kuti ichiritsidwe mwachangu, kuteteza chilengedwe ndi zabwino zina zamakampani osindikizira.Inki yosindikizira ya UV panthawi yonse yosindikiza, letterpress, kusindikiza kwa gravure, kusindikiza pazenera ndi kusindikiza kwa inkjet ndi magawo ena osindikizira, nkhaniyi ikugawana chidziwitso chokhudzana ndi inki ya UV, zomwe zili ndi anzanu:

Tanthauzo

UV: Wafupikitsa kuwala kwa ultraviolet.Ultraviolet (UV) ndi yosawoneka ndi maso.Ndi gawo la ma radiation a electromagnetic kupatula kuwala kofiirira kowoneka.Kutalika kwa mafunde kumakhala pakati pa 10 ~ 400nm

Inki ya UV: Inki ya UV, imatanthawuza kuwunikira kwa kuwala kwa UV pompopompo inki yochiritsa

Makhalidwe

1, kuthamanga kwa kuyanika kumathamanga, kupulumutsa nthawi, pansi pa kuyatsa kwa UV, kumafunika masekondi angapo mpaka masekondi angapo kuchiritsidwa.

2, zida chimakwirira dera laling'ono, osindikiza otaya ntchito, kupulumutsa anthu, phindu zachuma.

3, kuposa inki iliyonse kupatula zachilengedwe evaporation kuyanika inki, angapulumutse mphamvu.

4, pakakhala makulidwe ofanana a filimu yowuma, kupulumutsa kwa inki.

5, sichidzaphulika, bola ngati musagwirizane ndi cheza cha ultraviolet sichidzauma molimba pa inki.

6, kukhazikika kwamtundu wabwino.

7, kuwala kwakukulu.

8, tinthu tating'onoting'ono ta inki, timatha kusindikiza mawonekedwe abwino.

9, kusindikiza chilengedwe mpweya ndi watsopano, fungo laling'ono, palibe VOC.

Zosakaniza zazikulu

Zigawo zazikulu za inki ya UV zimaphatikizapo pigment, oligomer, monomer (yogwira diluent), photoinitiator ndi othandizira osiyanasiyana.Pakati pawo, utomoni ndi diluent yogwira ntchito ndi kukonza pigment ndi kupereka filimu kupanga katundu;Nkhumba imapatsa inki mtundu wocheperako komanso mphamvu yakuphimba ku gawo lapansi;Photoinitiator amafunikira kuti athe kuyamwa ma photon pansi pa kusokonezedwa kwa ma pigment kuti ayambitse polymerization.

1, Monomolecular Compounds (zowonjezera zosinthika)

Uwu ndi kaphatikizidwe wosavuta wokhala ndi mamolekyu ang'onoang'ono, amatha kuchepetsa kukhuthala, kuchita nawo gawo lobalalitsa, amatha kumwaza utoto, kusungunula utomoni, kudziwa kuthamanga kwa machiritso ndi kumamatira kwa inki, komanso kutenga nawo gawo mu utomoni wa UV kuchiritsa crosslinking reaction.

2, Zowonjezera

Kuphatikizapo inki, lubricant, thickening wothandizila, filler, solidifying wothandizira, etc. Zimakhudza inki gloss, mamasukidwe akayendedwe, softness, mtundu, filimu makulidwe, kuchiritsa liwiro, kuyenerera kusindikiza ndi katundu wina.

3, Utomoni Wowala Wolimba ndi Zida Zolumikizira Inki ya UV

Kuthamanga kwa inki ya UV, gloss, adhesion, kukana kukangana ndi zinthu zina, inki yosiyana imakhala ndi mitundu yosiyanasiyana ya utomoni wosakanikirana.

4, Woyambitsa Kuwala

Kuwala koyambitsa monga mlatho pakati pa mankhwala amachita, ndi mtundu wa chisangalalo kuwala kukhala yogwira kwambiri, pambuyo kuyamwa photons kubala ma free radicals, ufulu ankafuna kusintha kwakukulu kutengerapo mphamvu zina photosensitive polima, kupanga unyolo anachita, limodzi molekyulu zakuthupi, zowonjezera, kuwala olimba utomoni. pamodzi, kupanga inki kuchiritsa anachita, ndipo pambuyo amasulidwe mphamvu palokha si nawo crosslinking anachita.

Mfundo Yogwirizanitsa

Pansi pa kuyatsa kwa kuwala kwa ultraviolet, kuyatsa kwamphamvu koyambitsa magetsi kuti apange ma free radicals, kuchitapo kanthu mwachangu kwambiri, kugundana kumachitika ndi utomoni ndi molekyulu imodzi, kutengera mphamvu ku utomoni ndi mamolekyu amodzi, utomoni ndi mamolekyu amodzi. pambuyo kuyamwa mphamvu yokoka muna unsaturated awiri chomangira maatomu polymerized monoma polima ndi ma radicals, mwachitsanzo, utomoni ndi limodzi molekyulu mankhwala, Iwo amatsegula chomangira iwiri ndi kuyamba anachita mtanda kulumikiza, mankhwala yolumikizira mtanda, imene photoinitiator amataya mphamvu ndi kubwerera. ku chikhalidwe chake choyambirira.

Zomwe Zimakhudza

Inki yochiritsa ya UV iyenera kukhala ndi kuwala kwa UV kuti ichire, apo ayi singagwiritsidwe ntchito.Pogwiritsa ntchito inki ya UV, vuto loyamba lomatira ndiloti inki ya UV ilibe machiritso ozama.Pankhani ya zida zolimba zowala, chifukwa chake chingakhale kulephera kwa zida zochiritsira za UV, ndiko kuti, kutalika kwa mawonekedwe a zida zochiritsira za UV sizikugwirizana ndi inki yolimba ya UV, kapena mphamvu yolimba yowala sikokwanira, kapena kuthamanga kolimba sikuli kokwanira. zoyenera.

1, inki yopepuka ya UV yowala yowoneka bwino yowoneka bwino pakati pa 180-420NM.

2, mphamvu ya nyali ya UV iyenera kukwaniritsa zofunikira zaukadaulo pakuchiritsa kwa inki.

3, kuthamanga kusindikiza mwachangu kumakhudzanso kuthamanga kwa inki.

4, chikoka cha makulidwe a inki, inki yochuluka kwambiri idzakhudza kuchiritsa, zinthu zonse zomwe zimakhudza makulidwe a filimu yosindikizira zidzakhudza kuchiritsa.

5, zotsatira za nyengo: kutentha kwambiri, UV inki mamasukidwe akayendedwe kukhuthala amakhala otsika, pambuyo kusindikiza, zosavuta kupanga phala Baibulo chodabwitsa.Low kutentha, mkulu mamasukidwe akayendedwe, bwanji thixotropy wa inki, msonkhano kutentha sangakhale mkulu kwambiri, m'nyengo yozizira mu nyumba yosungiramo zinthu zoziziritsa kukhosi, ayenera kuika firiji, ndi yoyenera m'mbuyo kuchiritsa liwiro.

6, chikoka cha pigment pa UV inki: chifukwa mitundu yosiyanasiyana ya mayamwidwe kuwala, kunyezimiritsa ndi pigment zili inki ambiri, woyera, wakuda, buluu n'zovuta kuchiza, wofiira, wachikasu, kuwala mafuta, mandala mafuta mosavuta kuchiza. .
