Makhalidwe a Sodium Carboxymethyl Cellulose

Sodium carboxymethyl cellulose (CMC) ndi polima yosungunuka m'madzi, yomwe imachokera ku cellulose. Amapangidwa ndi zomwe cellulose imachita ndi chloroacetic acid ndi sodium hydroxide. CMC ili ndi zinthu zambiri zomwe zimapangitsa kuti zikhale zothandiza pamafakitale osiyanasiyana. Nazi zina mwazofunikira za CMC:

  1. Kusungunuka: CMC imasungunuka kwambiri m'madzi, zomwe zimapangitsa kuti zikhale zosavuta kuzigwira ndikugwiritsa ntchito pazinthu zosiyanasiyana. Itha kusungunukanso mu zosungunulira za organic, monga Mowa ndi glycerol, kutengera kuchuluka kwake m'malo.
  2. Viscosity: CMC ndi polymer yowoneka bwino kwambiri yomwe imatha kupanga ma gels pamalo okwera kwambiri. The mamasukidwe akayendedwe a CMC amatengera zinthu zosiyanasiyana, monga mlingo wa m'malo, ndende, pH, kutentha, ndi electrolyte ndende.
  3. Rheology: CMC imasonyeza khalidwe la pseudoplastic, zomwe zikutanthauza kuti kukhuthala kwake kumachepa ndi kuchuluka kwa kumeta ubweya. Katunduyu ndi wothandiza pamagwiritsidwe ntchito pomwe mamasukidwe apamwamba amafunikira pakukonza, koma kukhuthala kotsika kumafunika panthawi yogwiritsira ntchito.
  4. Zopangira mafilimu: CMC imatha kupanga makanema owonda, osinthika akawuma. Mafilimuwa ali ndi zotchinga zabwino ndipo amatha kugwiritsidwa ntchito ngati zokutira pazinthu zosiyanasiyana.
  5. Kukhazikika: CMC ndi yokhazikika pamitundu yosiyanasiyana ya pH ndi kutentha. Zimatsutsananso ndi kuwonongeka kwa tizilombo toyambitsa matenda, zomwe zimapangitsa kuti zikhale zoyenera kugwiritsidwa ntchito pazakudya ndi mankhwala.
  6. Kusungirako madzi: CMC imatha kuyamwa ndikusunga madzi, zomwe zimapangitsa kuti zikhale zothandiza pakugwiritsa ntchito komwe kusunga madzi ndikofunikira, monga pazogulitsa zamunthu, mankhwala, ndi zakudya.
  7. Kukhazikika kwa emulsion: CMC ingagwiritsidwe ntchito kukhazikika emulsions, yomwe ndi yofunika kwambiri popanga zinthu zosiyanasiyana, monga utoto, zomatira, ndi zokutira.
  8. Kumatira: CMC imatha kuwongolera kumamatira pazinthu zosiyanasiyana, monga zokutira, utoto, ndi zomatira.
  9. Kuyimitsidwa katundu: CMC akhoza kusintha katundu kuyimitsidwa mankhwala osiyanasiyana, monga suspensions wa inki, mchere, ndi particles zina.

Pomaliza, Sodium Carboxymethyl Cellulose (CMC) ndi polima wosunthika kwambiri yemwe amawonetsa zinthu zambiri, kuphatikiza kusungunuka, kukhuthala, rheology, kukhazikika, kupanga mafilimu, kusunga madzi, kukhazikika kwa emulsion, adhesion, ndi kuyimitsidwa. Izi zimapangitsa CMC kukhala yothandiza pamafakitale osiyanasiyana, monga chakudya, mankhwala, zinthu zosamalira anthu, ndi zotsukira, pakati pa ena.
