Cawv ntawm DS ntawm Carboxymethyl cellulose zoo

Cov degree ntawm kev hloov pauv (DS) yog qhov tseem ceeb heev uas cuam tshuam qhov zoo thiab kev ua tau zoo ntawm Carboxymethyl cellulose (cmc). DS hais txog qhov nruab nrab ntawm tus naj npawb ntawm Carboxymethyl pawg hloov mus rau txhua chav Anhydrogluce chav ntawm lub cellulose qaum caj cig. Tus nqi DS cuam tshuam rau ntau yam khoom ntawm CMC, suav nrog nws solubility, suav nrog lub peev xwm ua kom muaj peev xwm ua kom muaj peev xwm ua kom muaj zog. Ntawm no yog li cas DS cuam tshuam qhov zoo ntawm CMC:

1. Solubility:

• Low DS: CMC nrog qhov qis qis tshaj plaws yog qhov tsawg dua cov dej ntws vim muaj cov pawg thauj khoom uas muaj rau ionizes. Qhov no yuav ua rau qeeb qeeb cov nqi sib cav thiab cov sijhawm siv dej ntev dua.
• High DS: CMC nrog lub siab DS yog ntau soluble hauv dej, raws li nce tus naj npawb ntawm Carboxymethyl pab pawg thiab dispersibility ntawm cov saw polymer. Qhov no ua rau muaj kev sib cais sai dua thiab txhim kho cov khoom siv dej hauv dej.

2. Viscosity:

• Low DS: CMC nrog DS tsawg zaus feem ntau ua rau pom viscosity nyob rau qhov kev xav tau ntau dua rau cov qib siab dua. Cov pab pawg bailboxymethyl tshwm sim tsawg dua eric kev sib cuam tshuam thiab qaug zog polymer cov koom haum, ua kom qis viscosity.
• High DS: Ntau dua DS CMC cov qib nyiam kom muaj viscosity ntau dua vim muaj ionization ntau thiab muaj zog polymer cov kev sib cuam tshuam. Cov pab pawg uas muaj ntau dua ntawm cov roj carboxymethyl txhawb nqa ntau dua cov hydrogen dolring thiab entanglement, ua rau muaj kev daws teeb meem ntau dua.

3. Dej khaws cia:

• Tsawg DS: CMC nrog cov DS tsawg yuav tau txo cov dej khov dej kom muaj peev xwm piv rau cov qib siab dua DS. Cov pab pawg bailboxymethyl txwv tus naj npawb ntawm cov chaw muaj dej los ntawm kev siv dej tsoo thiab nqus, ua rau muaj dej tsawg dua.
• High DS: Cov qib siab ntau dua DS Qhov no ua kom cov polymer muaj peev xwm nqus tau thiab khaws nws cov kev ua tau zoo raws li cov tuab yaj ntawv, lossis cov kev tswj hwm noo noo.

4. Rheological Cwj Pwm:

• Low DS: CMC nrog qhov qis qis heev yuav muaj ntau cov neeg coj cwj pwm tshiab, nrog viscosity ntawm shear tus nqi. Qhov no ua rau nws haum rau cov ntawv teev cov ntaub ntawv ruaj khov hla ntau ntawm cov nqi shear, xws li kev ua zaub mov noj.
• High DS: Ntau dua DS CMC cov qib yuav ua rau pom ntau dua pseudopastic lossis shear-thuav tus cwj pwm, uas muaj viscosity txo nrog nce shear tus nqi. Cov cuab yeej no tau txais txiaj ntsig zoo rau cov ntawv thov tso dej, txau, lossis cov khoom lag luam zoo li qub lossis cov khoom siv saib xyuas tus kheej.

5. Kev ruaj khov thiab sib xyaw:

• Low DS: CMC nrog cov DS tsawg yuav nthuav tawm qhov ruaj khov zoo dua thiab sib xyaw nrog lwm cov khoom xyaw thiab cov kev sib cuam tshuam qis dua thiab tsis muaj zog. Qhov no tuaj yeem tiv thaiv theem sib cais, nag lossis daus, lossis lwm yam teeb meem ruaj khov hauv cov tshuab nyuaj.
• High DS: Ntau dua DS CMC cov qib yuav yog ntau dua kev nkag mus lossis theem sib cais hauv cov kev daws teeb meem lossis ntawm cov kev sib txuas lus kom muaj zog polymer. Ua tib zoo tsim qauv thiab kev ua yog qhov yuav tsum tau ua kom ntseeg tau tias muaj kev ruaj khov thiab sib xyaw ua ke hauv cov xwm txheej zoo li no.

Cov qib degree hloov pauv (DS) cuam tshuam qhov zoo, kev ua tau zoo, thiab haum cov carboxymethyl cellulose (cmc) rau ntau yam kev siv. Nkag siab txog kev sib txheeb ntawm DS thiab CMC cov khoom yog qhov tseem ceeb rau kev xaiv cov qib tsim nyog kom tau raws li cov kev ua tau zoo thiab kev ua tau zoo.
