Solubility ea sodium Carboxymethyl cellulose

Sodium carboxymethyl cellulose (CMC) ke polima e qhibilihang ka metsing e tsoang ho cellulose, polysaccharide ea tlhaho e fumanehang maboteng a lisele tsa semela. Ho qhibiliha ha CMC metsing ke e 'ngoe ea thepa ea eona ea bohlokoa' me e susumetsoa ke lintlha tse fapaneng, ho kenyelletsa tekanyo ea ho fetola (DS), boima ba limolek'hule, pH, mocheso le pherekano. Mona ke tlhahlobo ea ho qhibiliha ha sodium carboxymethyl cellulose:

1. Degree of Substitution (DS):

• Tekanyo ea ho nka sebaka e bolela palo e tloaelehileng ea lihlopha tsa carboxymethyl ka yuniti ea tsoekere ka ketane ea cellulose. Litekanyetso tse phahameng tsa DS li bonts'a tekanyo e kholo ea ho nkela sebaka le ho eketsa ho qhibiliha ha metsi.
• CMC e nang le boleng bo phahameng ba DS e atisa ho ba le ho qhibiliha ho betere ha metsi ka lebaka la bongata bo phahameng ba lihlopha tsa hydrophilic carboxymethyl haufi le ketane ea polymer.

2. Boima ba Molek'hule:

• Boima ba limolek'hule tsa CMC bo ka susumetsa ho qhibiliha ha eona metsing. CMC e phahameng ea boima ba limolek'hule e ka bonts'a sekhahla sa ho putlama butle ha se bapisoa le limaraka tse tlase tsa boima ba limolek'hule.
• Leha ho le joalo, hang ha e qhibilihisoa, CMC ea boima ba molek'hule e phahameng le e tlase hangata e theha tharollo e nang le thepa e tšoanang ea viscosity.

3. pH:

• CMC e tsitsitse ebile e qhibiliha ho feta mefuta e mengata ea pH, hangata ho tloha maemong a asiti ho ea ho alkaline.
• Leha ho le joalo, boleng bo feteletseng ba pH bo ka ama ho qhibiliha le botsitso ba tharollo ea CMC. Mohlala, maemo a asiti a ka protonate lihlopha tsa carboxyl, a fokotsa ho qhibiliha, athe maemo a alkaline a ka lebisa ho hydrolysis le ho senyeha ha CMC.

4. Mocheso:

• The solubility ea CMC ka kakaretso e eketseha ka mocheso. Lithempereichara tse phahameng li nolofatsa ts'ebetso ea ho qhibiliha 'me li etsa hore ho be le hydration e potlakileng ea likaroloana tsa CMC.
• Leha ho le joalo, litharollo tsa CMC li ka senyeha ka mocheso o phahameng, tse lebisang ho fokotseng viscosity le botsitso.

5. Khuduego:

• Ho ferekanngoa kapa ho kopanya ho matlafatsa ho qhibiliha ha CMC metsing ka ho eketsa ho kopana pakeng tsa likaroloana tsa CMC le limolek'hule tsa metsi, kahoo ho potlakisa ts'ebetso ea metsi.
• Ho ferekana ho lekaneng hangata hoa hlokahala ho fihlela ho felisoa ka botlalo ha CMC, haholo-holo bakeng sa limaraka tse phahameng tsa boima ba limolek'hule kapa litharollong tse tsepamisitsoeng.

6. Motsoako oa Letsoai:

• Ho ba teng ha matsoai, haholo-holo divalent kapa multivalent cations tse kang calcium ions, ka ama ho solubility le botsitso ba CMC tharollo.
• Matsoai a mangata a letsoai a ka lebisa ho thehoeng ha li-insoluble complexes kapa li-gel, ho fokotsa ho qhibiliha le ho sebetsa ha CMC.

7. Polymer Concentration:

• Ho qhibiliha ha CMC le hona ho ka susumetsoa ke khatello ea polymer ka tharollo. Maemo a phahameng a CMC a ka hloka linako tse telele tsa ho qhibiliha kapa ho eketseha ho tsitsipano ho fihlela metsi a felletseng.

Ka bokhutšoanyane, sodium carboxymethyl cellulose (CMC) e bonts'a ho qhibiliha ha metsi ka mokhoa o babatsehang ka holim'a maemo a mangata a fapaneng, e leng se etsang hore e be tlatsetso e fapaneng liindastering tse fapaneng. The solubility ea CMC e susumetsoa ke lintlha tse kang degree of substitution (DS), boima ba molek'hule, pH, mocheso, pherekano, mahloriso a letsoai le polymer concentration. Ho utloisisa lintlha tsena ho bohlokoa bakeng sa ho ntlafatsa tlhahiso le ts'ebetso ea lihlahisoa tse thehiloeng ho CMC lits'ebetsong tse fapaneng.
