Miyezo ya Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose(CMC) ndi polyanionic cellulose (PAC) amagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana monga thickeners, stabilizers, ndi rheology modifiers. Pofuna kuonetsetsa kuti ali ndi thanzi labwino komanso chitetezo, miyezo ingapo yakhazikitsidwa pazinthu izi. Miyezo yofunika kwambiri ya CMC ndi PAC ndi:

1. Food Chemicals Codex (FCC): Iyi ndi milingo yokhazikitsidwa ndi US Pharmacopeial Convention (USP) pazakudya, kuphatikiza CMC. FCC imakhazikitsa miyezo ya chiyero, kudziwika, ndi mtundu wa CMC womwe umagwiritsidwa ntchito popanga zakudya.

2. European Pharmacopoeia (Ph. Eur.): The Ph. Eur. ndi mndandanda wa miyezo ya zinthu zamankhwala zomwe zimagwiritsidwa ntchito ku Europe. Zimaphatikizapo ma monographs a CMC ndi PAC, omwe amakhazikitsa zofunikira ndi zoyera pazinthu izi zomwe zimagwiritsidwa ntchito popanga mankhwala.

3. American Petroleum Institute (API): API imakhazikitsa miyezo ya PAC yomwe imagwiritsidwa ntchito pobowola madzi m'makampani amafuta ndi gasi. API imatchula za katundu, ntchito, ndi zofunikira za PAC zomwe zimagwiritsidwa ntchito pobowola madzi.

4. International Organisation for Standardization (ISO): ISO yakhazikitsa miyezo ingapo ya CMC ndi PAC, kuphatikiza ISO 9001 (kayendetsedwe kabwino kabwino), ISO 14001 (system management system), ndi ISO 45001 (occupational health and safety management system).

5. Technical Association of the Pulp and Paper Industry (TAPPI): TAPPI yakhazikitsa miyezo ya CMC yomwe imagwiritsidwa ntchito pamakampani opanga mapepala. Miyezo iyi imanena za magwiridwe antchito ndi zofunikira za CMC zomwe zimagwiritsidwa ntchito ngati chowonjezera pamapepala.

Ponseponse, mfundozi zimathandizira kuwonetsetsa kuti CMC ndi PAC ndizokhazikika, zotetezeka komanso zosasinthika zomwe zimagwiritsidwa ntchito m'mafakitale osiyanasiyana. Kutsatira miyezo iyi ndikofunikira kwa opanga, ogulitsa, ndi ogwiritsa ntchito kumapeto kuti awonetsetse kuti zinthu zawo zikuyenda bwino komanso kuti zitetezeke.
