Cov ntsuas tseem ceeb los ntsuas qhov zoo ntawm CMC yog cov qib hloov pauv (DS) thiab purity. Feem ntau, cov khoom ntawm CMC muaj sib txawv thaum DS txawv; Qhov siab dua qib ntawm kev hloov pauv, zoo dua qub solubility, thiab qhov zoo dua lub pob tshab thiab kev ruaj khov ntawm kev daws. Raws li cov lus tshaj tawm, cov pob tshab ntawm CMC zoo dua thaum cov qib hloov pauv yog 0.7-1.2 loj tshaj plaws thaum tus nqi py yog 6-9.
Txhawm rau kom nws zoo, ntxiv rau kev xaiv ntawm kev sib raug zoo ntawm Alkali, qee yam kev sib cav, lub sijhawm siv kub, siv tus nqi thiab ntsev.
Sodium Carboxymethyl cellulose yog dav siv nyob rau hauv roj av, noj mov, yog li nws tseem ceeb heev rau kev txiav txim siab, thiab lick los txiav txim nws txoj kev coj dawb huv?
1. Sodium Carboxymethyl cellulose nrog cov kev ua kom siab siab, ua kom muaj lub teeb pom kev zoo, thiab nws cov dej khaws cia yog siab li 97%.
2. Cov khoom lag luam nrog cov kev tsis hnov tsw ntawm ammonia, cov hmoov txhuv nplej siab thiab dej cawv, tab sis yog tias lawv muaj ntxhiab tsw qab, lawv tuaj yeem hnov tsw qab qab qab.
3. Cov ntshiab sodium carboxymethyl cellulose yog flucy volually, thiab txoj kev ceev me me, cov ntau yog: 0.3 / ml; Lub fluentity ntawm kev deev yog qhov zoo dua, ob txhais tes xav tias hnyav dua, thiab muaj qhov sib txawv tseem ceeb nrog lub ntsej muag thawj.
4. Cov chloride cov ntsiab lus ntawm CMC feem ntau tau muab xam hauv cl, tom qab club cov ntsiab lus tau hloov mus ua cl% * 1.65
Muaj ib qho kev sib raug zoo ntawm CMC cov ntsiab lus thiab chloride, tab sis tsis yog txhua yam, muaj impurities xws li sodium glycolate. Tom qab paub txog kev coj dawb huv, cov ntsiab lus NACL tuaj yeem raug laij lej nacl% = (100-purity) /1.5
CL% = (100-purity) /1.5/1.65
Yog li ntawd, tus nplaig-licking khoom muaj cov ntsev qab ntsev zoo, qhia tias lub cev tsis huv yog qhov tsis siab.
Nyob rau tib lub sijhawm, siab-purity sodium carboxymethyl cellulose yog ib txwm fiber ntau lub xeev, thaum muaj cov khoom lag luam muaj txiaj ntsig yog granular. Thaum yuav cov khoom lag luam, koj yuav tsum kawm ntau txoj hauv kev yooj yim ntawm kev txheeb xyuas. Ib qho ntxiv, koj yuav tsum xaiv cov chaw tsim khoom siv nrog lub koob npe zoo, yog li cov khoom lag luam zoo tau qhuas.
