Cov Qauv rau Sodium Carboxymethylcellcellcaseculose / polyanionic cellulose

Sodium carboxymethylcelleculose (cmyanionic cellulose (xws li cov khoom noj, cov chaw muag tshuaj, tshuaj pleev ib ce, thiab dej huv. Cov ntaub ntawv no feem ntau ua rau cov qauv tshwj xeeb kom ntseeg tau tias zoo, kev nyab xeeb, thiab xwm yeem hauv lawv cov ntawv thov. Ntawm no yog qee cov qauv hais txog rau sodium carboxymethylcellcellcelleculose thiab polyanionic cellulose:

Sodium Carboxymetylcelleculose (CMC):

1. Kev Lag Luam Khoom Noj:
   • E466: Qhov no yog International Numbering system rau cov zaub mov ntxiv, thiab cmc yog muab tus lej e466 los ntawm Codex Alimentarius Commression.
   • ISO 7885: Tus qauv ISO no muab cov kev qhia tshwj xeeb rau CMC siv hauv cov khoom noj khoom haus, suav nrog cov qauv kev coj noj coj ua thiab cov khoom siv lub cev.
2. Kws Kev Lag Luam:
   • USP / NF: United States cov kws muag tshuaj / Tebchaws Hauv Tebchaws (USP / NF / NFITY rau CMC, qhia txog nws cov cwj pwm zoo, Purity xav tau, thiab kev ntsuam xyuas rau cov ntaub ntawv thov tshuaj.
   • EP: Cov kws kho mob European (EP)

Polyanionic cellulose (PAC):

1. Roj Drilling Kev Lag Luam:
   • API spec 13a: Qhov kev qhia tshwj xeeb no tau muab los ntawm American Petroleum Lub Koom Haum (API) muab cov kev xav tau rau cov kua roj av zom ua kua ntxiv. Nws suav nrog cov lus qhia tshwj xeeb rau kev coj dawb huv, kev faib tawm loj, rheological cov khoom, thiab tswj pom.
   • OCMA DF-CP-CP-CP-CP-CP-7: Tus qauv no, luam tawm los ntawm cov tuam txhab roj cov ntaub ntawv (OCMA), muab cov lus qhia rau kev ntsuam xyuas ntawm cov roj drilling kev siv.
