Cov qauv rau Sodium Carboxymethylcellulose / Polyanionic cellulose

Sodium carboxymethylcellulose(CMC) thiab polyanionic cellulose (PAC) yog dav siv nyob rau hauv ntau yam industries li thickeners, stabilizers, thiab rheology modifiers. Txhawm rau kom ntseeg tau tias lawv qhov zoo thiab kev nyab xeeb, ntau tus qauv tau tsim los rau cov tshuaj no. Qee cov qauv tseem ceeb tshaj plaws rau CMC thiab PAC yog:

1. Food Chemicals Codex (FCC): Qhov no yog cov txheej txheem tsim los ntawm US Pharmacopeial Convention (USP) rau cov khoom xyaw zaub mov, suav nrog CMC. FCC teeb tsa cov qauv rau kev coj dawb huv, tus kheej, thiab qhov zoo ntawm CMC siv hauv cov ntawv thov zaub mov.

2. European Pharmacopoeia (Ph. Eur.): Ph. Eur. yog ib qho kev sau los ntawm cov qauv rau cov tshuaj siv hauv Tebchaws Europe. Nws suav nrog monographs rau CMC thiab PAC, uas tsim kom muaj qhov zoo thiab purity yuav tsum tau rau cov tshuaj no siv nyob rau hauv kev siv tshuaj.

3. American Petroleum Institute (API): API tau teeb tsa cov qauv rau PAC siv rau hauv cov dej drilling hauv kev lag luam roj thiab roj. API qhia txog cov khoom, kev ua tau zoo, thiab cov kev xav tau zoo rau PAC siv hauv cov dej drilling.

4. International Organization for Standardization (ISO): Lub ISO tau tsim ntau yam qauv rau CMC thiab PAC, nrog rau ISO 9001 (zoo tswj system), ISO 14001 (ib puag ncig tswj system), thiab ISO 45001 (kev ua hauj lwm noj qab haus huv thiab kev nyab xeeb kev tswj system).

5. Technical Association ntawm Pulp thiab Paper Industry (TAPPI): TAPPI tau tsim cov qauv rau CMC siv hauv kev lag luam ntawv. Cov qauv no qhia txog kev ua tau zoo thiab cov kev xav tau zoo rau CMC siv los ua cov ntawv ntxiv.

Zuag qhia tag nrho, cov qauv no pab ua kom zoo, kev nyab xeeb, thiab sib xws ntawm CMC thiab PAC siv hauv ntau yam lag luam. Kev ua raws li cov qauv no yog qhov tseem ceeb rau cov tuam txhab, cov chaw muag khoom, thiab cov neeg siv khoom kawg kom ntseeg tau tias muaj txiaj ntsig thiab kev nyab xeeb ntawm lawv cov khoom.
