Ụkpụrụ maka sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) na polyanionic cellulose (PAC) bụ mkpụrụ ndụ cellulose nke a na-ejikarị eme ihe na ụlọ ọrụ dị iche iche, gụnyere nri, ọgwụ, ihe ịchọ mma, na mkpọ mmanụ. Ihe ndị a na-agbasokarị ụkpụrụ dị iche iche iji hụ na ịdịmma, nchekwa na nkwekọ na ngwa ha. Nke a bụ ụkpụrụ ụfọdụ a na-akpọkarị maka sodium carboxymethylcellulose na polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Ụlọ ọrụ nri:
   • E466: Nke a bụ usoro ọnụọgụ mba ụwa maka mgbakwunye nri, na Codex Alimentarius Commission kenyere CMC nọmba E466.
   • ISO 7885 ọkọlọtọ ISO a na-enye nkọwapụta maka CMC ejiri na ngwaahịa nri, gụnyere njirisi ịdị ọcha na akụrụngwa anụ ahụ.
2. Ụlọ ọrụ ọgwụ:
   • USP/NF: The United States Pharmacopeia/National Formulary (USP/NF) na-agụnye monographs maka CMC, na-akọwapụta àgwà ya, ịdị ọcha chọrọ, na ụzọ ule maka ngwa ọgwụ.
   • EP: European Pharmacopoeia (EP) tinyekwara monographs maka CMC, na-akọwapụta ụkpụrụ ịdị mma ya na nkọwapụta maka iji ọgwụ eme ihe.

Polyanionic Cellulose (PAC):

1. Ụlọ ọrụ na-egwupụta mmanụ:
   • API Spec 13A: Nkọwapụta a nke American Petroleum Institute (API) nyere na-enye ihe achọrọ maka cellulose polyanionic eji dị ka ihe mgbakwunye mmiri na-egwupu mmiri. Ọ na-agụnye nkọwapụta maka ịdị ọcha, nkesa nha urughuru, akụrụngwa rheological, na njikwa filtration.
   • OCMA DF-CP-7: Ụkpụrụ a, nke Òtù Na-ahụ Maka Ngwakọta Mmanụ Ala (OCMA) bipụtara, na-enye ntụziaka maka nleba anya nke cellulose polyanionic eji na ngwa ịkụ ala mmanụ.
