Ntchito za Sodium Carboxymethyl cellulose mu Kupaka Pigment

Sodium carboxymethyl cellulose (CMC) imagwiritsidwa ntchito kwambiri popanga utoto wa pigment pazifukwa zosiyanasiyana chifukwa cha mawonekedwe ake apadera. Nazi zina mwazofunikira za sodium carboxymethyl cellulose mu zokutira pigment:

1. Binder: CMC imagwira ntchito ngati chomangira pakupanga utoto wa pigment, kuthandiza kumamatira tinthu tating'ono ta pigment pamwamba pa gawo lapansi, monga pepala kapena makatoni. Zimapanga filimu yosinthika komanso yolumikizana yomwe imamangiriza tinthu tating'ono ta pigment ndikumangirira ku gawo lapansi, ndikuwongolera kumamatira ndi kulimba kwa zokutira.
2. Thickener: CMC imagwira ntchito ngati thickening muzopaka utoto wa pigment, kukulitsa kukhuthala kwa ❖ kuyanika. Kukhuthala kowonjezereka kumeneku kumathandizira kuwongolera kuyenda ndi kufalikira kwa zinthu zokutira panthawi yogwiritsira ntchito, kuwonetsetsa kuti yunifolomu yaphimba ndikupewa kugwa kapena kudontha.
3. Stabilizer: CMC imakhazikika ma dispersions a pigment mu ❖ kuyanika formulations poletsa tinthu aggregation ndi sedimentation. Zimapanga colloid zoteteza kuzungulira tinthu ta pigment, kuwalepheretsa kuti asatuluke pakuyimitsidwa ndikuwonetsetsa kugawidwa kwa yunifolomu pakusakaniza kwa zokutira.
4. Rheology Modifier: CMC imagwira ntchito ngati chosinthira ma rheology popanga utoto wa pigment, kuwongolera mayendedwe ndi mawonekedwe a zinthu zokutira. Zimathandizira kuwongolera magwiridwe antchito a zokutira, kulola kusalala komanso kugwiritsa ntchito pagawo laling'ono. Kuphatikiza apo, CMC imakulitsa kuthekera kwa zokutira kuti zithetse zolakwika ndikupanga kumaliza kofanana.
5. Wosungira Madzi: CMC imagwira ntchito ngati chosungira madzi mumipangidwe yokutira pigment, kuthandiza kuwongolera kuchuluka kwa kuyanika kwa zinthu zokutira. Imayamwa ndikugwira mamolekyu amadzi, kuchedwetsa kutuluka kwa nthunzi ndikukulitsa nthawi yowuma ya zokutira. Nthawi yowuma yotalikirayi imalola kuwongolera bwino ndikuchepetsa chiopsezo cha zolakwika monga kung'amba kapena matuza.
6. Surface Tension Modifier: CMC imasintha makulidwe amtundu wa utoto wa utoto, kuwongolera kunyowetsa ndi kufalikira. Zimachepetsa kuthamanga kwapamwamba kwa zinthu zophimba, zomwe zimalola kuti zifalikire mofanana pa gawo lapansi ndikumatira bwino pamwamba.
7. PH Stabilizer: CMC imathandizira kukhazikika kwa pH ya zopaka utoto wa pigment, kuchita ngati chotchinga kuti chisunge mulingo wa pH womwe ukufunidwa. Zimathandizira kupewa kusinthasintha kwa pH komwe kungakhudze kukhazikika ndi magwiridwe antchito a zinthu zokutira.

sodium carboxymethyl cellulose imagwira ntchito yofunika kwambiri popanga utoto wa pigment pogwira ntchito ngati binder, thickener, stabilizer, rheology modifier, posungira madzi, pamwamba tension modifier, ndi pH stabilizer. Katundu wake wochita ntchito zambiri amathandizira kuti kumamatira kumatira bwino, kufananiza, kulimba, komanso mtundu wonse wazinthu zomalizidwa.
