Maemo a Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) le polyanionic cellulose (PAC) ke lintho tse nkiloeng ho cellulose tse sebelisoang haholo liindastering tse fapaneng, ho kenyeletsoa lijo, meriana, litlolo le ho cheka oli. Lisebelisoa tsena hangata li latela litekanyetso tse ikhethileng ho netefatsa boleng, polokeho le botsitso lits'ebetsong tsa tsona. Mona ke tse ling tsa litekanyetso tse tloaelehileng tsa sodium carboxymethylcellulose le polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Indasteri ea Lijo:
   • E466: Ena ke tsamaiso ea machaba ea linomoro bakeng sa li-additives tsa lijo, 'me CMC e fuoa nomoro ea E466 ke Khomishene ea Codex Alimentarius.
   • ISO 7885: Tekanyetso ena ea ISO e fana ka litlhaloso bakeng sa CMC e sebelisoang lihlahisoa tsa lijo, ho kenyeletsoa mekhoa ea bohloeki le thepa ea 'mele.
2. Indasteri ea Litlhare:
   • USP/NF: The United States Pharmacopeia/National Formulary (USP/NF) e kenyelletsa monographs bakeng sa CMC, e hlalosang litšobotsi tsa eona tsa boleng, litlhoko tsa bohloeki, le mekhoa ea tlhahlobo ea likopo tsa meriana.
   • EP: The European Pharmacopoeia (EP) e boetse e kenyelletsa monographs bakeng sa CMC, e hlalosang litekanyetso tsa eona tsa boleng le litlhaloso bakeng sa tšebeliso ea meriana.

Polyanionic Cellulose (PAC):

1. Indasteri ea ho Cheka Oli:
   • API Spec 13A: Tlhaloso ena e fanoeng ke American Petroleum Institute (API) e fana ka litlhoko tsa polyanionic cellulose e sebelisoang e le motsoako oa ho cheka mokelikeli. E kenyelletsa lintlha tsa bohloeki, kabo ea boholo ba likaroloana, thepa ea rheological, le taolo ea ho sefa.
   • OCMA DF-CP-7: Tekanyetso ena, e hatisitsoeng ke Oil Companies Materials Association (OCMA), e fana ka litataiso bakeng sa tlhahlobo ea cellulose ea polyanionic e sebelisoang lits'ebetsong tsa ho cheka oli.

Qetello:

Maemo a bapala karolo ea bohlokoa ho netefatsa boleng, polokeho le ts'ebetso ea sodium carboxymethylcellulose (CMC) le polyanionic cellulose (PAC) liindasteri tse fapaneng. Ho lumellana le litekanyetso tse amehang ho thusa bahlahisi le basebelisi ho boloka botsitso le ho ts'epahala lihlahisoa tsa bona le lits'ebetso. Ho bohlokoa ho bua ka maemo a ikhethileng a sebetsang molemong oa ts'ebeliso e reriloeng ea CMC le PAC ho netefatsa taolo e nepahetseng ea boleng le tumellano ea melao.
