Uruhare n'Imikoreshereze Ishya ya CMC mu Nganda z'Icapiro

Selulose ya karboksimetili (CMC), ikomoka kuri selulosi ishongesha amazi kandi ikora neza, ifite akamaro kanini mu gucapa wino, impumuro zipfundikiye, n'ibikoresho byo gupfunyika. Bitewe n'iterambere ry'ikoranabuhanga ryo gucapa rigana ku muvuduko wo hejuru, kurengera ibidukikije, no gukoresha ikoranabuhanga, CMC, ifite ubushobozi bwo gukurura, gukora filime, gukwirakwiza no kubika amazi, irimo kuba inyongeramusaruro y'ingenzi mu kunoza ireme ry'icapiro.

1. Uruhare rw'ingenzi rwa CMC mu buryo bwo gucapa

1.1. Kugabanya ububyimba no kugenzura imitsi y'amaraso

CMC ifite ingaruka zikomeye zo gukuba, ikagenzura imikorere ya wino cyangwa imvange. Igumana ubukana runaka iyo sisitemu iri mu mwanya wayo kandi ikagabanya ubukana iyo icuzwe, bigatuma amazi atemba neza. Iyi miterere ya rheological ya "pseudoplastic" ifasha kwimura wino mu buryo buhamye mu gihe cyo gucapa, yirinda ibibazo nko gusya wino, gufunga imigozi, cyangwa gucika, bityo ikarushaho kunoza imiterere y'imirongo icapwa.

1.2. Ingaruka zo gukwirakwiza no gutuza

Mu irangi ry’amabara, CMC ishobora kwinjira ku buso bw’uduce tw’amabara, igakora charge ihamye cyangwa ingaruka zo kubangamira steric, ikongera ikwirakwira ry’amabara no kugabanya ukwiyongera kw’uduce. Sisitemu yo gukwirakwiza amabara ihamye ntiyongerera imbaraga zo gusiga irangi gusa no guhisha imbaraga ahubwo inanongera igihe cyo kumara wino.

1.3. Gutunganya no kunoza uburyo bwo gufata filime

Nyuma yo kuma, CMC igaragaza ubushobozi bwiza bwo gukora firime, ikora urwego rumwe rwo gufatana ku mpapuro cyangwa ku buso bwa firime, yongera isano iri hagati ya wino n'ubutaka, kandi ikongera ubushobozi bwo kudashwanyagurika, kudashwanyagurika kw'amazi, no kuramba k'urwego rwacapwe.

1.4. Kubungabunga ubushuhe n'ingaruka zo kurwanya kurumisha

Mu irangi rishingiye ku mazi no mu icapiro rya flexographic, CMC ishobora kugabanya neza umuvuduko w’umuvuduko w’ikirahure ku isahani yo gucapa cyangwa mu bubiko bw’irangi, ikarinda kuziba kw’isahani no kunoza uburyo icapiro rihoraho rihagarara.

2. Imiterere isanzwe ya CMC mu nganda z'icapiro

2.1. Sisitemu za Wino zishingiye ku mazi

CMC ikoreshwa ku bwinshi mu irangi rikozwe mu mazi n'iry'imashini zicapa zikoresheje gravure, yongera ubukana, gukwirakwira no guhagarara, kandi yongera ubwiza bw'ishusho. Imiterere yayo irinda ibidukikije kandi idafite uburozi ituma iba ikoreshwa cyane kuruta imashini zisanzwe zikora ibintu bishya.

2.2. Impapuro zipfundikiye n'impapuro zidasanzwe

Mu buryo bwo gusiga impapuro zitwikiriwe, ikarito yera, n'impapuro z'umuco, CMC ikoreshwa nk'igikoresho cyo guhuza no guhindura imiterere y'impapuro, gitera inkunga ikorwa rya firime imwe kandi kikanoza uburyo impapuro zigenda neza, zigasa neza, kandi zigacapa neza. Cyane cyane mu mpapuro zitwikiriwe neza, CMC ishobora kunoza ikwirakwizwa ry'uduce tw'ibara, bigatuma haboneka ibisobanuro birambuye.

2.3. Inki zo gucapa inkjet

Bitewe n'iterambere ry'ikoranabuhanga rya inkjet, CMC ikomeje gukoreshwa cyane muri sisitemu za inkjet zikoresha amazi:

Kugenzura imiterere n'ikwirakwira ry'ibitonyanga;

Kunoza ibara rihamye;

Kugabanya umuvuduko wo kuziba kw'imitwe y'inyandiko.

Bifasha kunoza ireme ry'amashusho mu buryo bworoshye nko gucapa amafoto no gucapa ibirango.

2.4. Ibikoresho byo gucapa no guhuza ibiryo

CMC ni nziza kandi ntigira uburozi kandi ishobora gukoreshwa mu buryo bwo gucapa irangi ry’ibiribwa kugira ngo ifashe mu kunoza uburyo bwo gufatana no kwirinda amavuta, mu gihe ihuye n’ibisabwa mu bidukikije nko kwangirika kw’ibinyabuzima no kugabanuka kw’impinduka mu buryo budakwiye.

3. Imiterere mishya y'ikoreshwa rya CMC mu nganda z'icapiro

3.1. Guteza imbere CMC yo Gusimburana no Gukora neza

Mu kongera urugero rwo gusimbuza (DS) no kuba ibintu bimwe, ubushobozi bwo kurwanya umunyu, gukorera mu mucyo no kubyimba bishobora kunozwa cyane, bigatuma biba byiza cyane ku irangi ry’amazi n’irya inki rikoresha inki nyinshi.

3.2. Ikoranabuhanga ryo Kuvanga Ibara rya Nanoscale

KuvangaCMChamwe na nano-pigments bishobora kunoza uburyo bwo gukwirakwira kw'amabara, kugabanya ingano y'uduce tw'ibara ry'umukara, no kongera ubwinshi bw'amabara n'ibisobanuro mu icapiro rifite ubushobozi bwo gucapa buri hejuru.

3.3. Inyongeramusaruro y'ibanze ku buryo amazi akoreshwa mu bidukikije kandi adafite ingaruka ku bidukikije

Kubera ko hari amategeko akomeye ya VOC, icyifuzo cy’imashini zikoresha amazi n’amavanishi akoresha amazi kirimo kwiyongera cyane. Nk’ibikoresho bikomoka ku bimera, CMC ishobora kongera gukoreshwa kandi ibora, ikaba igice cy’ingenzi cy’imashini zikoresha wino y’icyatsi kibisi.

3.4. Kwagura CMC mu icapiro ry'ikoranabuhanga

Mu guhindura uburemere bwa molekile n'urwego rwa viscosity, CMC ishobora guhindurwa kugira ngo icape ikoresheje inkjet yihuta cyane, inoze uburyo bwo kugenzura amadomo kandi itanga ituze n'ubudahangarwa byo hejuru mu icapiro rya elegitoroniki.
