Ukusetshenziswa CMC in ezinengilazi
CMC,i-sodium carboxymethyl cellulose, inezinhlobonhlobo zezinhlelo zokusebenza embonini yezingubo zokumboza, ikakhulukazi esebenza njenge-thickener, stabilizer, kanye nosizo lokwenza ifilimu, edlala indima ebalulekile ekuthuthukiseni ukusebenza kwe-coating. Ngezansi ukuhlaziya okuningiliziwe kwezicelo ze-CMC embonini yokumboza:
1. Ukuqina Komphumela
I-CMC, inhlanganisela ye-polymer yemvelo encibilikayo emanzini, ingakhuphula ngempumelelo i-viscosity yezingubo futhi ilawule izakhiwo zayo ze-rheological, yenze ukunamathela kube bushelelezi futhi kube lula ukukusebenzisa. Ngokulawula inani le-CMC engeziwe, umuntu angakwazi ukulungisa kahle ukuhambisana kwamapende e-latex, ngaleyo ndlela athuthukise ukusebenza kwawo kwesicelo, ehlise ukuconsa, athuthukise ukusebenza kahle kokwakhiwa, futhi aqinisekise ukunamathela okulinganayo.
2. Ukuzinzisa Umphumela
Ama-pigments kanye nama-fillers e-coating ngokuvamile avame ukuhlala, okuholela ekuhlanganiseni kwe-coating. Ukwengezwa kwe-CMC kungathuthukisa kakhulu ukuzinza kwezingubo, kuvimbele ukuxazululwa kwezingulube nama-fillers, nokugcina izigqoko zifana futhi zingaguquguquki ngesikhathi sokugcina nokusebenzisa. Ikakhulukazi ngesikhathi sokugcina isikhathi eside, umphumela wokuzinzisa we-CMC ubaluleke kakhulu. Isakhiwo senethiwekhi esakhiwe yi-CMC singavimbela ngokuphumelelayo ukuxazululwa kwezingulube nama-fillers, ukugcina ukuhlakazeka nokufana kwezingubo.
3. Umphumela Wosizo Lokwenza Ifilimu
I-CMC idlala indima eyisizayo enqubweni yokwenza ifilimu yokumboza, yenze ukujiya okubunjiwe kuqine futhi kube bushelelezi ngemva kokomiswa. Lokhu akuthuthukisi nje kuphela ikhwalithi yokubukeka kwe-coating, njengokunciphisa izimpawu zebhulashi kanye nemiphumela yekhasi lewolintshi, kodwa futhi kuthuthukisa ukumelana nokugqoka kwe-coating, ukumelana nokuguga, nokumelana namanzi, ngaleyo ndlela kunwebe impilo yesevisi ye-coating.
4. Ukusebenza Kwemvelo
Ngokukhula okuqhubekayo kwezidingo zokuvikela imvelo, ukumbozwa kwamanzi sekuyinto evamile emakethe.I-CMC, njengesengezo sokuhlanganisa esinobungani bemvelo, ayinazo izinto eziyingozi futhi ihlangabezana nezindinganiso zikazwelonke zokuvikela imvelo. Ukusetshenziswa kwe-CMC ekugqokeni akukwazi nje ukunciphisa okuqukethwe kwe-VOCs (izinto eziphilayo ezishintshayo) kodwa futhi kuthuthukise ukusebenza kwemvelo kwezingubo, ukuhlangabezana nezidingo zentuthuko esimeme zomphakathi wanamuhla.
5. Uhla Olubanzi Lwezicelo
I-CMC ayifanele nje kuphela opende abavamile be-latex kanye nama-coatings asekelwe emanzini kodwa futhi nezinkambu zokunamathela ezikhethekile ezifana nezingubo zezimoto, okokunamathela olwandle, okokumboza kwebanga lokudla, kanye nezingubo zokwelashwa. Kule mikhakha, i-CMC ingathuthukisa kakhulu ukuqina nokumelana nokugqwala kwezingubo, iqinisekise ukuphepha nokuvikelwa kwemvelo kwemikhiqizo.
Kafushane, i-CMC inamathuba abanzi okusebenza kanye nenani elibalulekile lesicelo embonini yezingubo zokugqoka. Ayithuthukisi nje kuphela ukusebenza kanye nekhwalithi yezingubo zokumboza kodwa futhi ihlangabezana nezidingo zomphakathi wanamuhla zokuvikelwa kwemvelo kanye nentuthuko eqhubekayo. Ngokuthuthuka okuqhubekayo kwemboni yokumboza, i-CMC ngokungangabazeki izodlala indima ebaluleke kakhulu emakethe yesikhathi esizayo.
