Kuaj cov teeb uas Carboxymethyl Cellulose Substitution(DS)

1. acidity titration CMC naj muab teeb ib vas nthiv thiab yooj yim
Hluas, zoo tshaj, tshwj xeeb tshaj yog txais nyob rau hauv ntau ntau li thiab teb siv.
2. titration acidity yuav tsis tsuas yog siv los ntsuas lub CMC zoo li naj
Cov neeg kawm ntawv cov khoom uas muab, kuj yuav siv los txiav txim seb flies zoo ib yam li cov qauv ntawm cov ntaub
Teeb muab cov hmoov txhuv nplej siab methyl.
3. cov neeg kawm ntawv uas tau muab ib yam li 0.4 rau lub CMC naj qauv acidity
Cov kev ntsuas tau ntau yog suav titration, rau cov neeg kawm ntawv uas muab ntawm 0.4 tsawg tshaj
CMC naj coj, kev ntsuas seb ua tau ashing yuam kev yog me me thiab. Vim hais tias hloov
Siab tshaj 0.4 CMC naj zoo coj cov water-soluble, thiab muab cov teeb
Tsawg tshaj. .4 naj coj cov water-soluble cMC txom nyem dej solubility, nws yuav zoo dua
Kuaj nrog ib pH ' meter ' titration tau ntsuas dua kom yog yog. Oilfield
Naj CMC ntsev ntawm ib feem ntau ntawm cov neeg kawm ntawv uas tau muab ib yam li 0.4, ces cov pH ' meter '
Titration muaj ntau hauv lub tshav pob roj.
