Tulaga mo Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) ma polyanionic cellulose (PAC) o selulose derivatives lautele faaaogaina i alamanuia eseese, e aofia ai meaai, pharmaceuticals, cosmetics, ma suauu viliina. O nei mea e masani ona mulimulitaʻi i tulaga faʻapitoa e faʻamautinoa ai le lelei, saogalemu, ma le tumau ia latou talosaga. O nisi nei o tulaga masani fa'asino mo le sodium carboxymethylcellulose ma polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Alamanuia Taumafa:
   • E466: Ole numera fa'ava-o-malo lea mo mea'ai faaopoopo, ma o le CMC ua tu'uina atu ile E466 e le Codex Alimentarius Commission.
   • ISO 7885: O lenei tulaga ISO o loʻo tuʻuina atu ai faʻamatalaga mo CMC faʻaaogaina i meaʻai, e aofia ai tulaga mama ma mea faʻaletino.
2. Alamanuia tau vailaau:
   • USP/NF: O le United States Pharmacopeia/National Formulary (USP/NF) e aofia ai monokalafi mo le CMC, fa'amaoti ona uiga lelei, mama mana'oga, ma metotia su'esu'e mo fa'aoga vaila'au.
   • EP: O le European Pharmacopoeia (EP) o lo'o aofia ai fo'i monokalafi mo le CMC, fa'amatalaina ona tulaga lelei ma fa'amatalaga mo le fa'aogaina o vaila'au.

Polyanionic Cellulose (PAC):

1. Alamanuia vili Suau'u:
   • API Spec 13A: O lenei faʻamatalaga na tuʻuina atu e le American Petroleum Institute (API) e tuʻuina atu ai manaʻoga mo cellulose polyanionic faʻaaogaina e fai ma faʻapipiʻi sua sua. E aofia ai faʻamatalaga mo le mama, tufatufaina atu o vaega laiti, meatotino rheological, ma le faʻatonutonuina o le faamamaina.
   • OCMA DF-CP-7: O lenei tulaga, lomia e le Oil Companies Materials Association (OCMA), o loʻo tuʻuina atu ai taʻiala mo le iloiloga o le polyanionic cellulose o loʻo faʻaaogaina i suauʻu viliina talosaga.

Fa'ai'uga:

O tulaga fa'ata'atia e iai sona sao taua i le fa'amautinoaina o le lelei, saogalemu, ma le fa'atinoga o le sodium carboxymethylcellulose (CMC) ma le polyanionic cellulose (PAC) i pisinisi eseese. O le tausisia o tulaga fa'atatau e fesoasoani i tagata gaosi oloa ma tagata fa'aoga e fa'amautu le tumau ma le fa'amaoni i a latou oloa ma fa'aoga. E taua le fa'asino i tulaga fa'apitoa e fa'atatau i le fa'aogaina o le CMC ma le PAC e fa'amautinoa ai le fa'atonutonuina lelei ma le tausisia o tulafono fa'atonutonu.
