Zomwe Zimayambitsa pa carboxymethylcellulose sodium salt Solution Khalidwe

Carboxymethylcellulose sodium mchere (CMC-Na) ndi polima wosungunuka m'madzi womwe umagwiritsidwa ntchito kwambiri m'mafakitale ndi malonda osiyanasiyana, kuphatikiza chakudya, mankhwala, ndi zinthu zosamalira anthu. Khalidwe la mayankho a CMC-Na limakhudzidwa ndi zinthu zingapo, zina zomwe zikukambidwa pansipa:

1. Kulemera kwa mamolekyu: Kulemera kwa mamolekyu a CMC-Na kumakhudza momwe amayankhira, kukhuthala kwake, komanso mawonekedwe ake. Ma polima olemera kwambiri a CMC-Na amakhala ndi ma viscosity apamwamba kwambiri ndipo amawonetsa kumeta ubweya wambiri kuposa ma molekyulu otsika.
2. Kuyikirapo: Kukhazikika kwa CMC-Na mu yankho kumakhudzanso machitidwe ake. Pamalo otsika kwambiri, mayankho a CMC-Na amakhala ngati amadzimadzi a Newtonian, pomwe ali okwera kwambiri, amakhala owoneka bwino kwambiri.
3. Mphamvu ya Ionic: Mphamvu ya ionic yankho imatha kukhudza machitidwe a CMC-Na mayankho. Kuchuluka kwa mchere wambiri kungapangitse CMC-Na kuphatikizika, zomwe zimapangitsa kuti kuchuluke kukhuthala komanso kuchepa kwa kusungunuka.
4. pH: The pH yankho imathanso kukhudza machitidwe a CMC-Na. Pamitengo yotsika ya pH, CMC-Na imatha kukhala protonated, zomwe zimapangitsa kuti kuchepeko kusungunuke komanso kuchulukira kukhuthala.
5. Kutentha: Kutentha kwa yankho kungakhudze khalidwe la CMC-Na posintha kusungunuka kwake, kukhuthala kwake, ndi khalidwe la gelation. Kutentha kwapamwamba kungapangitse kusungunuka kwa CMC-Na, pamene kutentha kochepa kungayambitse gelation.
6. Kumeta ubweya wa ubweya: Kumeta ubweya wa ubweya kapena kuthamanga kwa yankho kungakhudze khalidwe la CMC-Na posintha kukhuthala kwake ndi rheological properties. Pakumeta ubweya wambiri, njira za CMC-Na sizikhala zowoneka bwino komanso zometa ubweya wambiri.

Ponseponse, machitidwe a CMC-Na mayankho amakhudzidwa ndi zinthu zingapo, kuphatikiza kulemera kwa maselo, kukhazikika, mphamvu ya ionic, pH, kutentha, ndi kumeta ubweya. Kumvetsetsa zinthu izi ndikofunikira pakupanga ndi kukhathamiritsa ma CMC-Na-based formulations osiyanasiyana.
