Miyezo ya Sodium Carboxymethylcellulose/ Polyanionic cellulose

Sodium carboxymethylcellulose (CMC) ndi polyanionic cellulose (PAC) ndizochokera ku cellulose zomwe zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, kuphatikiza chakudya, mankhwala, zodzoladzola, ndi kubowola mafuta. Zidazi nthawi zambiri zimatsatira miyezo yapadera kuti zitsimikizire kuti zili bwino, zotetezeka, komanso zimasinthasintha pazogwiritsa ntchito. Nayi milingo yodziwika bwino ya sodium carboxymethylcellulose ndi polyanionic cellulose:

Sodium Carboxymethylcellulose (CMC):

1. Makampani a Chakudya:
   • E466: Iyi ndi njira yapadziko lonse yowerengera zakudya zowonjezera, ndipo CMC imapatsidwa nambala E466 ndi Codex Alimentarius Commission.
   • ISO 7885: Mulingo wa ISO uwu umapereka mafotokozedwe a CMC omwe amagwiritsidwa ntchito muzakudya, kuphatikiza njira zachiyero ndi mawonekedwe akuthupi.
2. Makampani Azamankhwala:
   • USP/NF: The United States Pharmacopeia/National Formulary (USP/NF) imaphatikizapo ma monographs a CMC, kufotokoza makhalidwe ake abwino, zofunikira za chiyero, ndi njira zoyesera zogwiritsira ntchito mankhwala.
   • EP: European Pharmacopoeia (EP) imaphatikizanso zolemba za CMC, kufotokoza za miyezo yake yabwino komanso momwe amagwiritsidwira ntchito pamankhwala.

Ma cellulose a Polyanionic (PAC):

1. Makampani Obowola Mafuta:
   • API Spec 13A: Izi zoperekedwa ndi American Petroleum Institute (API) zimapereka zofunikira pa polyanionic cellulose yomwe imagwiritsidwa ntchito ngati chowonjezera chamadzimadzi. Zimaphatikizapo tsatanetsatane wa chiyero, kagawidwe ka kukula kwa tinthu, mawonekedwe a rheological, ndi kuwongolera kusefera.
   • OCMA DF-CP-7: Mulingo uwu, wofalitsidwa ndi Oil Companies Materials Association (OCMA), umapereka malangizo owunikira mapadi a polyanionic omwe amagwiritsidwa ntchito pobowola mafuta.

Pomaliza:

Miyezo imagwira ntchito yofunika kwambiri pakuwonetsetsa kuti sodium carboxymethylcellulose (CMC) ndi polyanionic cellulose (PAC) imakhala yabwino, yotetezeka komanso yogwira ntchito m'mafakitale osiyanasiyana. Kutsatira miyezo yoyenera kumathandiza opanga ndi ogwiritsa ntchito kukhala osasinthasintha komanso odalirika pazogulitsa ndi ntchito zawo. Ndikofunikira kutchulanso mfundo zomwe zikuyenera kugwiritsidwa ntchito pa CMC ndi PAC kuti muwonetsetse kuwongolera koyenera komanso kutsata malamulo.
