Teko Standard-ASTM e466 Sodium Carboxymethylcellulose

ASTM E466 ke mokhoa o tloaelehileng oa tlhahlobo o fanang ka ts'ebetso ea ho khetholla viscosity ea sodium carboxymethylcellulose (CMC) metsing kapa li-solvents tse ling. Mokhoa ona o atisa ho sebelisoa ho lekanya tekanyo ea polymerization le boemo ba ho nkela sebaka sa CMC, hammoho le ho netefatsa ho lumellana ha lisampole tsa CMC bakeng sa merero ea ho laola boleng.

Mokhoa oa teko o kenyelletsa ho lokisa tharollo ea CMC metsing kapa mokelikeli o mong o loketseng le ho lekanya viscosity ea eona ka viscometer. Viscosity e lekanyetsoa ka mocheso o itseng le sekhahla sa ho kuta, se boletsoeng ho maemo. Tekanyetso e boetse e fana ka litataiso tsa ho lokisa tharollo ea CMC, hammoho le litaelo tsa ho lekanya le ho sebetsa viscometer.

Ntle le ho lekanya viscosity, standard ea ASTM E466 e boetse e kenyelletsa lits'ebetso tsa ho lekanya thepa e meng ea CMC, joalo ka pH, molora, le mongobo. Thepa ena e ka ama ts'ebetso ea CMC lits'ebetsong tse fapaneng, 'me ho bohlokoa ho netefatsa hore e kopana le litlhaloso tse hlokahalang.

Ka kakaretso, tekanyetso ea ASTM E466 e fana ka mokhoa o tsitsitseng le o ka tšeptjoang oa ho lekanya viscosity le thepa e meng ea sodium carboxymethylcellulose. Sena se thusa ho netefatsa botsitso le boleng ba lihlahisoa tsa CMC mme se nolofalletsa bahlahisi ho fihlela litlhoko tsa bareki ba bona liindastering tse fapaneng.
