Carboxymethyl cellulose (CMC), chinhu chinobva mu cellulose chinonyungudika mumvura, chinoshandiswa zvakanyanya muinki dzekudhinda, pulps dzakaputirwa, uye zvinhu zvekurongedza. Nekuvandudzwa kwetekinoroji yekudhinda inoenda kukukurumidza kwakanyanya, hushamwari kune zvakatipoteredza, uye digitalization, CMC, ine hunhu hwayo hwakanaka hwekukora, kugadzira firimu, kupararira, uye kuchengetedza mvura, iri kuva chinhu chakakosha chinobatsira pakuvandudza kunaka kwekudhinda.
- Basa Guru reCMC muKudhinda Masisitimu
1.1. Kusimba uye Kudzora Maronda Emudumbu
CMC ine simba guru rekukora, ichidzora maitiro e inki kana coating solutions. Inochengetedza viscosity yakati kana system yacho yamira uye inoderedza viscosity kana yachekwa, zvichivandudza kufamba kwemvura. Iyi "pseudoplastic" rheological properties inobatsira inki kutamiswa zvakanaka panguva yekudhinda, kudzivirira matambudziko akadai sekupararira kwe inki, stringing, kana sagging, nokudaro ichivandudza kujeka uye kufanana kwemitsetse yakadhindwa.
1.2. Mhedzisiro yeKupararira uye Kugadzikana
Muma inki ane pigment, CMC inogona kunyungudutsa pamusoro pezvikamu zve pigment, zvichiita kuti pave nechaji yakagadzikana kana kuti steric inhibition effect, zvichivandudza kupararira kwepigment uye kuderedza kuunganidzwa kwezvikamu. Sisitimu yekupararira kwepigment yakagadzikana haingowedzere simba rekupenda uye simba rekuviga chete asiwo inowedzera hupenyu hwesherufu yeinki.
1.3. Kugadzirwa kwemafirimu uye Kuvandudzwa kweKunamira
Mushure mekuomeswa, CMC inoratidza hunhu hwakanaka hwekugadzira firimu, ichigadzira jira rekunamatira rakafanana pamapepa kana pamusoro pefirimu, ichisimbisa chisungo chiri pakati peinki nepasi, uye ichivandudza kuramba kwekukwesha, kuramba mvura, uye kugara kwenguva refu kwejira rakadhindwa.
1.4. Kuchengetedza Hunyoro uye Kudzivirira Kuomesa
Muinki dzinobva mumvura uye mukudhinda kweflexographic, CMC inogona kuderedza zvakanyanya kuoma kweinki papureti yekudhinda kana musystem yekuchengetera inki, kudzivirira kuvharika kweplate uye kuvandudza kugadzikana kwekudhinda kunoenderera mberi.
- Maitiro Akajairika Ekushandisa CMC Muindasitiri Yekudhinda
2.1. Masisitimu eInki Anobva Mumvura
CMC inoshandiswa zvakanyanya muinki dzekudhinda dzinobva mumvura uye dzinoshandisa flexographic, zvichivandudza kunaka, kupararira, uye kugadzikana, uye zvichiwedzera kuzara kwemufananidzo. Hunhu hwayo husingakuvadzi nharaunda uye husina chepfu hunoita kuti ive imwe nzira inofarirwa pane zvigadzirwa zvechinyakare.
2.2. Kugadzirwa kwePepa Rakafukidzwa uye Mapepa Akakosha
Mukuita machira ekuputira mapepa akaputirwa, kadhibhodhi jena, uye mapepa etsika, CMC inoshandiswa semuchina wekubatanidza uye rheology modifier, iyo inokurudzira kuumbwa kwefirimu yakafanana uye inovandudza kutsetseka kwepepa, kupenya, uye kudhindwa. Kunyanya mumapepa ane kupenya kwakanyanya, CMC inogona kuvandudza kugoverwa kwezvidimbu zvepigment, zvichikonzera ruzivo rwakajeka.
2.3. Inki dzekudhinda dzeInkjet
Nekuvandudzwa kwetekinoroji ye inkjet, CMC iri kushandiswa zvakanyanya mumasisitimu e inkjet emvura:
Kudzora chimiro chedonhwe uye kupararira kwaro;
Kuvandudza kugadzikana kwemavara;
Kuderedza mwero wekuvharika kwemusoro wekudhinda.
Zvinobatsira kuvandudza kunaka kwemifananidzo munzvimbo dzakanyatsogadzirwa dzakadai sekudhinda mifananidzo uye kudhinda mazita.
2.4. Kudhinda Pakurongedza uye Zvinhu Zvekubata Chikafu
CMC yakachengeteka uye haina chepfu uye inogona kushandiswa muzvirongwa zveinki zvekudhinda chikafu kuti ibatsire kuvandudza kunamira uye kuramba mafuta, uku ichisangana nezvinodiwa zvakatipoteredza zvakaita sekuora kwezvinhu uye kusafamba zvakanaka.
- Maitiro Ekushandisa Atsva eCMC muIndasitiri Yekudhinda
3.1. Kuvandudzwa kweHigh Substitution uye Functionalized CMC
Nekuwedzera mwero wekutsiva (DS) uye kufanana, kuramba munyu, kujeka, uye kushanda zvakanaka kwekukora zvinogona kuvandudzwa zvakanyanya, zvichiita kuti ive yakakodzera inki dzemvura dzakasimba uye inki dzeinkjet.
3.2. Tekinoroji yeKusanganisa Pigment yeNanoscale
KusanganisaCMCine nano-pigments inogona kuvandudza kugadzikana kwekupararira, kuderedza saizi yeinki, uye kuwedzera kuwanda kwemavara neruzivo mukudhinda kwemhando yepamusoro.
3.3. Chinhu Chinowedzerwa Chekushandisa Mvura Yakachena Uye Inodzivirira Kupararira Kwezvakatipoteredza
Nekuomeswa kuri kuramba kuchiwedzera kwemitemo yeVOC, kudiwa kweinki dzemvura nemavarnish emvura kuri kuwedzera nekukurumidza. Sezvinhu zvinobva muzvisikwa, CMC inogona kushandiswazve uye kuora, ichiva chikamu chakakosha chemafomu einki yegirini.
3.4. Kuwedzera kweCMC mukudhinda kwedhijitari
Nekugadzirisa huremu hwemamorekuru uye giredhi rekupenya, CMC inogona kugadziriswa kuti idhindwe nekukasira kwekudhinda kweinkjet, ichivandudza kurongeka kwekudzora madonhwe uye ichipa kugadzikana kwakanyanya uye kugara kwenguva refu kwekudhinda kwedhijitari.
