Kugwiritsa ntchito Hydroxypropyl Methyl Cellulose mu Kusindikiza kwa Ink

Kugwiritsa ntchito kwaHydroxypropyl Methyl Cellulosemu Ink Printing

Inkiyi imapangidwa ndi inki, zomangira ndi zida zothandizira (hydroxypropyl methylcellulose), zomwe zimasakanizidwa ndikukulungidwa.

Wokonzeka inki. Mtundu, thupi (kawirikawiri rheological katundu wa inki monga kugwirizana woonda ndi fluidity amatchedwa thupi la inki) ndi kuyanika ntchito ndi zinthu zitatu zofunika kwambiri inki.

Instant hydroxypropyl methylcellulose yosindikiza inki ndi ufa woyera wopanda fungo, wosakoma, wopanda poizoni.

Imafufuma kukhala njira yowoneka bwino kapena yamtambo pang'ono ya colloidal m'madzi ozizira. Lili ndi makhalidwe a thickening, kugwirizana, kubalalika, emulsification, filimu-kupanga, kuyimitsidwa, adsorption, gelation, pamwamba ntchito, kusunga madzi ndi colloid zoteteza. amatenga gawo lofunikira mu.

Hydroxypropyl methylcellulose ili ndi ma viscosity atatu a 100,000, 150,000, ndi 200,000. The mamasukidwe akayendedwe ndi khalidwe la inki madzimadzi otaya.

Chizindikiro cha kuchuluka kwa kukana (kapena kukangana kwamkati) kuyenda. M'kati mwa offset kusindikiza, kukhuthala kwina n'kofunika kusunga inki kutengerapo bwinobwino.

Ndilo chikhalidwe chachikulu choperekera ndi kusuntha, komanso ndi chikhalidwe chofunikira chodziwira kufulumira, kumveka bwino ndi gloss ya kusindikiza. Kukhuthala kwa inki

Ngati ndi yaikulu kwambiri, zidzakhala zovuta kusamutsa ndi kusamutsa, kotero kuti kuchuluka kwa inki pamapangidwewo kudzakhala kosakwanira, zomwe zimapangitsa maliseche a zithunzi ndi malemba kuti apange chitsanzo. Mofananamo, viscosity

Ngati ndi yayikulu kwambiri, ndizosavuta kupangitsa kuti pepala likhale lopangidwa ndi ufa, kapena kuyambitsa kupukuta kwa pepala losindikizidwa. Koma ngati mamasukidwe akayendedwe ndi ochepa kwambiri, n'zosavuta kupanga

Kuyandama ndi zauve, zidzachititsa inki emulsification mu milandu kwambiri, ngati sangathe kukhala kufala yachibadwa ndi kutengerapo, ndipo pang'onopang'ono inki.

Tinthu ta pigment timaunjikana pa zodzigudubuza, mbale zosindikizira ndi mabulangete, ndipo kudzikundikirako kukafika pamlingo winawake, kumayambitsa kuphulika.

Hydroxypropyl methyl celluloseali ndi zomatira zabwino, kupewa kumamatira kwa inki panthawi yosindikiza

Sichikugwirizana ndi ntchito ndi kusindikiza zinthu za gawo lapansi, chifukwa pepala ufa, lint, osauka inki overprinting, kusindikiza

Zolephera zosindikiza monga mbale zakuda.

3

Hydroxypropyl methylcellulose ali ndi thixotropy wabwino, kupewa thixotropy wa inki panthawi yosindikiza.

Zolephera zosindikiza monga "kutuluka kwa inki kosakwanira", kusamutsa kwa inki kosafanana, ndi kukulitsa kwakukulu kwa madontho oyambitsidwa ndi zoyipa.

Hydroxypropyl methylcellulose imakhala ndi zomatira kwambiri, panthawi yosindikizira, mphamvu yolembera inki sikuti imangolunjika.

Zimagwirizana ndi zotsatira zosindikizira komanso ubwino wa chinthu chosindikizidwa, komanso zimagwirizana kwambiri ndi kuchuluka kwa inki pagawo lililonse. Ngati mungasankhe

Kugwiritsa ntchito inki zokhala ndi ma tin amphamvu kumawononga inki yocheperako poyerekeza ndi inki zokhala ndi mphamvu zopendekera zofooka, ndipo zotsatira zabwino zosindikiza zitha kupezeka.

Hydroxypropyl methylcelluloseali ndi madzimadzi abwino kwambiri, inki yabwino ya fluidity, ndi kusinthasintha mu kasupe wa inki

Ili ndi luso lolemba bwino komanso luso lolemba bwino; kusamutsa ndi kusamutsa pakati pa zodzigudubuza inki kapena pakati pa mbale yosindikizira ndi bulangeti kulinso kwabwino;

Inki wosanjikiza ndi yunifolomu; filimu ya inki yosindikizidwa ndi yosalala komanso yosalala. Ngati fluidity ndi yaing'ono kwambiri, n'zosavuta chifukwa osauka inki kumaliseche; kugawa kosafanana kwa inki wosanjikiza, etc.

chodabwitsa, pamwamba pa kusindikizidwa inki filimu adzaoneka ripples. Pamene fluidity ndi yaikulu kwambiri, woonda inki wosanjikiza n'zosavuta chifukwa madontho kukulitsa, kusindikiza

Mtunduwu si wamphamvu. Njira yoyendera mita imagwiritsidwa ntchito kwambiri.
