Kukopa zinthu pa sodium carboxymethycelulose

Makutu a sodium carboxymethylceloulose (cmc) amatha kutengera zinthu zingapo. Nazi zina mwazinthu zazikulu zomwe zimakhudza mafayilo a cMC:

1. Kuzindikira: Makutu a ma cMC nthawi zambiri amawonjezeka ndi kuchuluka kwambiri. Kukhazikika kwakukulu kwa cmc kumapangitsa maunyolo ambiri polymer mu njirayi, kumapangitsa kuti zikhale zokulirapo kwambiri komanso mafayilo apamwamba. Komabe, pali malire pa ufawo kuwonjezeka kwa zinthu zapamwamba chifukwa cha zinthu zomwe monga njira yothetsera vuto la polymer.
2. Madigirikiti a zolowa (DS): Mlingo wa cholowa m'malo mwa magulu a carboxymethyl a gulu la glucose mu cellulose unyolo. CMC yokhala ndi DS yokwera imakhala ndi mamasukidwe apamwamba chifukwa imakhala ndi magulu oyimbidwa ambiri, omwe amalimbikitsa kuyang'aniridwa mwamphamvu komanso kukana kwakukulu.
3. Kulemera kwa maselo: Kuchepetsa thupi kwa cmc kumatha kukhudza ma viscty. Chuma chambiri cha masentimita kwambiri chimabweretsa njira zapamwamba za mafayilo chifukwa cha kuchuluka kwa unyolo ndi unyolo wautali. Komabe, mochulukitsa kwambiri masentimita CMC zitha kuchititsa kuti chisamaliro chikuwonjezeredwa popanda kuwonjezeka kwamphamvu.
4. Kutentha: Kutentha kumakhala ndi vuto lalikulu pakukusintha kwa ma cMC. Mwambiri, ma virud amachepetsa monga kutentha kumawonjezereka chifukwa cha kusanthula polima polymer ndi kusungunuka moled. Komabe, zotsatira za kutentha pa ufa zimatha kusiyanasiyana malinga ndi zinthu monga polymer ndende, maselo olemera a PH.
5. PH: PH of the CMC yankho limatha kukhudza ma visckeds ake chifukwa cha kusintha kwa ma politetion ndi njira. CMC imakhala yowoneka bwino kwambiri pamakhalidwe apamwamba a pH chifukwa magulu a Carboxymethyl ali ndi linited, zomwe zimapangitsa kuti zikhale zolimba pakati pa ma polymer. Komabe, mikhalidwe ya ph kwambiri imatha kusintha kusintha kwa polime ndikusintha, komwe kumakhudzanso mafayilo osiyanasiyana kutengera kalasi ya CMC ndi kapangidwe kake ka CMC.
6. Mchere: Kukhalapo kwa mchere mu yankho kumatha kusintha mafayilo a CMC kudzera pakusintha kwa polymer-solvection ndi ma poltory. Nthawi zina, kuwonjezera mchere mchere kumatha kukulira ma Iscluon poyang'ana unyolo pakati pa polymer
7. Mtengo wometa ubweya: Makutu a cmc amathanso kumadalira mtengo wake kapena kuchuluka komwe kupsinjika kumayikidwa pa yankho. Mayankho a CMC nthawi zambiri amawonetsa khalidwe la shear, pomwe ma visked amachepetsa ndikuwonjezereka chifukwa cha kuphatikizidwa ndi mawonekedwe a ma polymer maunyolo motsatira njira yolowera. Kuchepa kwa shear kumatha kusiyanasiyana malinga ndi zinthu monga polymer ndende, maselo olemera a PH.

Makutu a mapangidwe a sodium carboxymethylmelose mayankho amatengera kuphatikiza kwa zinthu kuphatikiza, kuchuluka kwa zowonjezera, puta, mchere, ndi mtengo wamchere. Kuzindikira zinthuzi ndikofunikira kuti muthe kukweza masinthidwe a CMC ya mapulogalamu enaake m'mafakitale monga chakudya, mankhwala, komanso chisamaliro chaumwini.
