Kugwiritsa Ntchito Hydroxypropyl Methyl Cellulose Posindikiza Inki

Kugwiritsa ntchitoHydroxypropyl Methyl cellulosemu Kusindikiza Inki

Inkiyo imapangidwa ndi utoto, zomangira ndi zinthu zina zothandizira (hydroxypropyl methylcellulose), zomwe zimasakanizidwa ndikuzunguliridwa.

Inki yokonzeka kugwiritsidwa ntchito. Mtundu, thupi (nthawi zambiri mphamvu za inki monga kusinthasintha kowonda komanso kusinthasintha kwake zimatchedwa thupi la inki) ndi magwiridwe antchito owuma ndi zinthu zitatu zofunika kwambiri za inki.

Instant hydroxypropyl methylcellulose yosindikizira inki ndi ufa woyera wopanda fungo, wopanda kukoma, komanso wopanda poizoni.

Imatupa kukhala yankho loyera kapena la mitambo pang'ono la colloidal m'madzi ozizira. Ili ndi mawonekedwe a kukhuthala, kugwirizana, kufalikira, emulsification, kupanga filimu, kuyimitsidwa, kulowetsedwa, gelation, ntchito pamwamba, kusunga madzi ndi colloidal yoteteza. Imachita gawo lofunikira kwambiri.

Hydroxypropyl methylcellulose ili ndi kukhuthala katatu kwa 100,000, 150,000, ndi 200,000. Kukhuthala ndi khalidwe la kuyenda kwa madzi a inki.

Chizindikiro cha kuchuluka kwa kukana (kapena kukangana kwamkati) ku kuyenda. Pakusindikiza kwa offset, kukhuthala kwina ndikofunikira kuti inki isamutsidwe bwino.

Ndi chinthu chofunikira kwambiri potumiza ndi kusamutsa, komanso ndi chinthu chofunikira kwambiri podziwa kufulumira, kumveka bwino komanso kunyezimira kwa chizindikirocho.

Ngati ndi yayikulu kwambiri, zidzakhala zovuta kusamutsa ndi kusamutsa, kotero kuti kuchuluka kwa inki pa kapangidwe kake sikudzakhala kokwanira, zomwe zimapangitsa kuti zithunzi ndi zolemba zisakhale zachikazi kuti zipange chitsanzo. Momwemonso, kukhuthala kwa thupi

Ngati ndi yayikulu kwambiri, zimakhala zosavuta kuti pepalalo lisungunuke ndi kuphwanyidwa, kapena kuti pepala losindikizidwa lichotsedwe. Koma ngati kukhuthala kwake kuli kochepa kwambiri, n'kosavuta kupanga.

Poyandama komanso poyipa, imayambitsa kusakaniza kwa inki m'njira yovuta kwambiri, ngati singapitirize kutumiza ndi kusamutsa bwino, komanso pang'onopang'ono mu inki.

Tinthu ta utoto timasonkhana pa ma rollers, ma printing plates ndi mabulangeti, ndipo pamene kuchulukanako kufika pamlingo winawake, kumayambitsa matope.

Hydroxypropyl methyl celluloseIli ndi guluu wabwino, imapewa guluu womatira wa inki panthawi yosindikiza

Sichikugwirizana ndi momwe zinthu zilili komanso momwe zimagwiritsidwira ntchito posindikiza, zomwe zimapangitsa kuti pepala likhale lopanda utoto, lint, inki isamasindikizidwe bwino, komanso kuti isindikizidwe bwino.

Kulephera kusindikiza monga mbale zodetsedwa.

Hydroxypropyl methylcellulose ili ndi thixotropy yabwino, yopewa thixotropy ya inki panthawi yosindikiza.

Kulephera kusindikiza monga "kuyenda bwino kwa inki", kusamutsa inki mosagwirizana, komanso kufalikira kwakukulu kwa madontho chifukwa cha zoyipa.

Hydroxypropyl methylcellulose imakhala ndi guluu wolimba kwambiri, ndipo posindikiza kwa offset, mphamvu yopaka utoto ya inki si yolunjika yokha.

Zimakhudzana ndi momwe kusindikiza kumagwirira ntchito komanso mtundu wa chinthu chosindikizidwa, komanso zimagwirizana kwambiri ndi kuchuluka kwa inki pa gawo lililonse. Ngati mungasankhe

Kugwiritsa ntchito inki yokhala ndi mphamvu yopaka utoto kumatenga inki yochepa kuposa inki yokhala ndi mphamvu yopaka utoto yochepa, ndipo zotsatira zabwino zosindikizira zingapezeke.

Hydroxypropyl methylcelluloseIli ndi kusinthasintha kwabwino kwambiri, inki yosinthasintha bwino, komanso kusinthasintha kwa kasupe wa inki

Ili ndi luso labwino lolemba inki komanso luso labwino lolemba inki; kusamutsa ndi kusamutsa pakati pa ma rollers a inki kapena pakati pa mbale yosindikizira ndi bulangeti ndikwabwinonso;

Gawo la inki ndi lofanana; filimu ya inki yosindikizidwa ndi yosalala komanso yosalala. Ngati madzi ake ndi ochepa kwambiri, n'zosavuta kuyambitsa kutuluka kwa inki kosakwanira; kufalikira kosagwirizana kwa gawo la inki, ndi zina zotero.

Chodabwitsa n'chakuti, pamwamba pa filimu ya inki yosindikizidwa padzawonekeranso mafunde. Pamene madzi akutuluka kwambiri, wosanjikiza woonda wa inkiyo umakhala wosavuta kuyambitsa kukula kwa madontho, kusindikiza.

Mtundu wake si wolimba. Njira yoyezera kuchuluka kwa madzi imagwiritsidwa ntchito kwambiri.
