I-Carboxymethyl cellulose (CMC), i-cellulose encibilika emanzini esebenza kahle kakhulu, inezinhlelo zokusebenza eziningi kuma-inki okunyathelisa, ama-pulp amboziwe, kanye nezinto zokupakisha. Ngokuthuthuka kobuchwepheshe bokunyathelisa kuya ngesivinini esiphezulu, ubungane bemvelo, kanye nokwenza kube yidijithali, i-CMC, enezakhiwo zayo ezinhle kakhulu zokuqina, ukwakha ifilimu, ukuhlakazeka, kanye nokugcina amanzi, isiba yisithasiselo esibalulekile esisebenzayo sokuthuthukisa ikhwalithi yokunyathelisa.
- Indima Eyinhloko Ye-CMC Ezinhlelweni Zokuphrinta
1.1. Ukuqina Nokulawulwa Kwe-Rheological
I-CMC inomphumela obalulekile wokujiya, ilawula ukuziphatha kwe-rheological kwama-inki noma izixazululo zokumboza. Igcina i-viscosity ethile lapho uhlelo luphumulile futhi inciphisa i-viscosity ngaphansi kokucheba, ithuthukisa ukugeleza. Le mpahla ye-rheological "ye-pseudoplastic" isiza ukudlulisa i-inki ngokuzinzile ngesikhathi sokuphrinta, igwema izinkinga ezifana nokuqhekeka kwe-inki, ukubopha, noma ukugoba, ngaleyo ndlela ithuthukise ukucaca kanye nokufana kwemigqa ephrintiwe.
1.2. Imiphumela Yokuhlakazeka Nokuzinza
Kuma-inki e-pigment, i-CMC ingamunca phezu kwezinhlayiya ze-pigment, yakhe ishaja ezinzile noma umphumela wokuvimbela i-steric, ithuthukise ukusabalala kwe-pigment futhi inciphise ukuhlanganiswa kwezinhlayiya. Uhlelo lokusabalala kwe-pigment oluzinzile alugcini nje ngokuthuthukisa amandla okufaka imibala kanye namandla okufihla kodwa futhi lwandisa isikhathi sokuphila kweshalofu le-inki.
1.3. Ukwakhiwa Kwefilimu Nokuthuthukiswa Kokunamathela
Ngemva kokomiswa, i-CMC ikhombisa izakhiwo ezinhle kakhulu zokwakha ifilimu, yakha ungqimba lokunamathela olufanayo ephepheni noma ebusweni befilimu, ithuthukisa isibopho phakathi kweyinki nesisekelo, futhi ithuthukisa ukumelana nokuguguleka, ukumelana namanzi, kanye nokuqina kokusebenza kwengqimba ephrintiwe.
1.4. Ukugcinwa Komswakama kanye Nemiphumela Yokulwa Nokomisa
Kuyinki esuselwe emanzini kanye nokuphrinta kwe-flexographic, i-CMC inganciphisa ngempumelelo izinga lokomisa kweyinki epuletini lokuphrinta noma ohlelweni lokugcina uyinki, ivimbele ukuvaleka kwepuleti futhi ithuthukise ukuzinza kokuphrinta okuqhubekayo.
- Izimo Ezijwayelekile Zokusetshenziswa kwe-CMC Embonini Yokuphrinta
2.1. Izinhlelo Zoyinki Ezisekelwe Emanzini
I-CMC isetshenziswa ngobuningi obukhulu kuma-inki okunyathelisa asekelwe emanzini kanye ne-flexographic, ithuthukisa i-viscosity, ukuhlakazeka, kanye nokuqina, futhi ithuthukisa ukugcwala kwesithombe. Izakhiwo zayo ezinobungani nemvelo kanye nezingabuthi ziyenza ibe yindlela ekhethwayo kunezithisi zokwenziwa zendabuko.
2.2. Ukukhiqizwa Kwephepha Elimboziwe kanye Nephepha Elikhethekile
Ezinqubweni zokumboza iphepha elimboziwe, ikhadibhodi elimhlophe, kanye nephepha lamasiko, i-CMC isetshenziswa njenge-binder kanye ne-rheology modifier, ekhuthaza ukwakheka kwefilimu efanayo futhi ithuthukise ukushelela kwephepha, ukucwebezela, kanye nokunyatheliswa. Ikakhulukazi emaphepheni acwebezelayo kakhulu, i-CMC ingathuthukisa ukusatshalaliswa kwezinhlayiya ze-pigment, okuholela emininingwaneni ecacile.
2.3. Ama-inki Okuphrinta I-inkjet
Ngokuthuthuka kobuchwepheshe be-inkjet, i-CMC isetshenziswa kakhulu ezinhlelweni ze-inkjet ezisekelwe emanzini:
Ukulawula ukuma kwamaconsi kanye nokusabalala kwawo;
Ukuthuthukisa ukuzinza kombala;
Ukunciphisa izinga lokuvaleka kwekhanda lokuphrinta.
Kuyasiza ekuthuthukiseni ikhwalithi yezithombe emikhakheni enembile kakhulu njengokuphrinta izithombe kanye nokuphrinta amalebula.
2.4. Izinto Zokunyathelisa Nokuxhumana Nokudla Eziphathelene Nokupakisha
I-CMC iphephile futhi ayinabo ubuthi futhi ingasetshenziswa ezinhlelweni ze-inki zokuphrinta ukudla ukuze isize ekuthuthukiseni ukunamathela kanye nokumelana namafutha, ngenkathi ihlangabezana nezidingo zemvelo ezifana nokubola kanye nokufuduka okuphansi.
- Izindlela Zokusebenza Ezintsha ze-CMC Embonini Yokuphrinta
3.1. Ukuthuthukiswa kwe-CMC Efaka Ushintsho Oluphezulu kanye Nemisebenzi Esebenzayo
Ngokwandisa izinga lokushintshaniswa (DS) kanye nokufana, ukumelana nosawoti, ukucaca, kanye nokusebenza kahle kokujiya kungathuthukiswa kakhulu, okwenza kube kuhle kakhulu kuma-inki asekelwe emanzini aqinile kanye nama-inki e-inkjet.
3.2. Ubuchwepheshe Bokuhlanganisa I-Nanoscale Pigment
UkuhlanganisaI-CMCngama-nano-pigments kungathuthukisa ukuzinza kokusabalala, kunciphise usayizi wezinhlayiya zeyinki, futhi kuthuthukise ukugcwala kombala kanye nemininingwane ekuphrinteni okunesisombululo esiphezulu.
3.3. Isithasiselo Esiyinhloko Sezinhlelo Zamanzi Eziluhlaza Nezinobungani Nemvelo
Njengoba kunemikhawulo eqinile ye-VOC, isidingo sama-inki asekelwe emanzini kanye nama-varnish asekelwe emanzini sikhula ngokushesha. Njengezinto ezitholakala ngokwemvelo, i-CMC ivuseleleka futhi iyabola, iba yingxenye ebalulekile yezakhiwo ze-inki eluhlaza.
3.4. Ukwandiswa kwe-CMC ekuphrinteni kwedijithali
Ngokulungisa isisindo sama-molecule kanye nezinga le-viscosity, i-CMC ingenziwa ngokwezifiso zokuphrinta kwe-inkjet okusheshayo, ithuthukise ukunemba kokulawula amaconsi futhi inikeze ukuzinza okuphezulu nokuqina kokuphrinta kwedijithali.
