Kev cuam tshuam ntawm DS ntawm carboxymethyl cellulose Zoo

Degree of Hloov (DS) yog ib qho tseem ceeb tsis zoo uas cuam tshuam qhov zoo thiab kev ua tau zoo ntawm Carboxymethyl Cellulose (CMC).DS hais txog qhov nruab nrab ntawm cov carboxymethyl pawg hloov mus rau txhua chav anhydroglucose ntawm cov pob txha cellulose.Tus nqi DS cuam tshuam rau ntau yam khoom ntawm CMC, suav nrog nws cov solubility, viscosity, dej tuav peev xwm, thiab tus cwj pwm rheological.Nov yog li cas DS cuam tshuam qhov zoo ntawm CMC:

1. Solubility:

• Tsawg DS: CMC nrog qis DS zoo li tsis tshua muaj dej nyob hauv dej vim muaj tsawg carboxymethyl pawg muaj rau ionization.Qhov no yuav ua rau qeeb qeeb qeeb thiab lub sij hawm hydration ntev dua.
• High DS: CMC nrog lub siab DS yog ntau soluble nyob rau hauv dej, raws li tus naj npawb ntawm carboxymethyl pawg pab txhawb lub ionization thiab dispersibility ntawm cov polymer chains.Qhov no ua rau kom tawg sai dua thiab txhim kho hydration zog.

2. Viscosity:

• Tsawg DS: CMC nrog DS qis feem ntau pom cov viscosity qis dua ntawm qhov muab piv rau qib DS siab dua.Cov pawg carboxymethyl tsawg dua ua rau muaj kev sib cuam tshuam ionic tsawg dua thiab tsis muaj zog ntawm cov saw hlau polymer, ua rau qis viscosity.
• High DS: Cov qib DS CMC siab dua yuav muaj viscosity ntau dua vim muaj zog ionization thiab muaj zog polymer saw sib cuam tshuam.Cov pawg carboxymethyl ntau dua txhawb nqa ntau dua hydrogen bonding thiab entanglement, ua rau cov viscosity ntau dua.

3. Kev tuav dej:

• Tsawg DS: CMC nrog DS qis yuav muaj peev xwm khaws dej tsawg dua piv rau qib DS siab dua.Cov pawg carboxymethyl tsawg dua txwv cov chaw muaj nyob rau hauv cov dej khi thiab nqus dej, ua rau cov dej qis dua.
• High DS: Cov qib DS CMC siab dua feem ntau pom cov dej tuav tau zoo dua vim tias muaj cov carboxymethyl pawg ntau ntxiv rau dej.Qhov no txhim kho cov polymer lub peev xwm los nqus thiab khaws dej, txhim kho nws cov kev ua tau zoo raws li cov thickener, binder, los yog noo noo regulator.

4. Rheological cwj pwm:

• Tsawg DS: CMC nrog qis DS zoo li muaj ntau tus cwj pwm Newtonian ntws, nrog viscosity ywj siab ntawm shear npaum li cas.Qhov no ua rau nws haum rau cov ntawv thov kom ruaj khov viscosity dhau ntau yam ntawm cov nqi shear, xws li hauv kev ua zaub mov.
• High DS: Cov qib DS CMC siab dua tuaj yeem pom ntau tus cwj pwm pseudoplastic lossis shear-thinning tus cwj pwm, qhov twg viscosity txo qis nrog kev nce shear.Cov cuab yeej no muaj txiaj ntsig zoo rau cov ntawv thov kom yooj yim ntawm cov twj tso kua mis, txau, lossis sib kis, xws li hauv cov xim pleev xim lossis cov khoom siv tu tus kheej.

5. Stability thiab Compatibility:

• Tsawg DS: CMC nrog qis DS tuaj yeem ua kom muaj kev ruaj ntseg zoo dua thiab sib haum nrog lwm cov khoom xyaw hauv cov qauv vim nws qhov qis ionization thiab kev sib cuam tshuam tsis zoo.Qhov no tuaj yeem tiv thaiv theem sib cais, nag lossis daus, lossis lwm yam teeb meem kev ruaj ntseg hauv cov txheej txheem nyuaj.
• High DS: Cov qib DS CMC siab dua tuaj yeem ua rau cov gelation lossis theem sib cais hauv cov kev daws teeb meem siab lossis kub siab vim muaj kev sib cuam tshuam ntawm cov polymer.Ua tib zoo tsim thiab ua tiav yuav tsum tau ua kom muaj kev ruaj ntseg thiab sib haum xeeb hauv cov xwm txheej zoo li no.

Degree of Hloov (DS) cuam tshuam rau qhov zoo, kev ua tau zoo, thiab kev tsim nyog ntawm Carboxymethyl Cellulose (CMC) rau ntau yam kev siv.Kev nkag siab txog kev sib raug zoo ntawm DS thiab CMC cov khoom yog qhov tseem ceeb rau kev xaiv cov qib uas tsim nyog kom ua tau raws li cov kev cai tshwj xeeb thiab cov qauv kev ua haujlwm.
