Kev loj hlob ntawm rheological thickener

Kev loj hlob ntawm cov tuab tuab, suav nrog cov uas muaj cov neeg muaj kev cuam tshuam ntawm cov qauv carboxymethyl ntawm cov qauv molecular ntawm cov polymer kom ua tiav cov khoom ntawd. Ntawm no yog ib tug txheej txheem cej luam ntawm txoj kev txhim kho:

1. Rheological yuav tsum muaj: thawj kauj ruam hauv kev tsim cov tuab tuab hauv kev tsim cov ntaub ntawv uas xav tau rau cov ntawv thov. Qhov no suav nrog tsis xws li viscosity, shear thinning tus cwj pwm, tawm tsam kev ntxhov siab, thiab thixotrotropy. Cov ntawv thov sib txawv kuj yuav xav tau sib txawv cov khoom sib txawv raws li kev ua kom zoo ib yam li cov kev lis kev cai, kev siv cov kev thov, thiab xaus kev xav tau kev xav tau ua tau zoo.
2. Cov kev xaiv polymer: Thaum cov rheological cov cai tau txhais, haum polymers yog xaiv raws li lawv cov khoom sib xyaw thiab sib xyaw nrog kev tsim qauv. Cellulose Cov neeg muaj kev hais zoo li CMC feem ntau xaiv rau lawv cov tuab heev, ruaj khov, thiab cov dej-khaws cov khoom. Qhov hnyav molecular, qib degree hloov chaw, thiab hloov chaw qauv ntawm cov polymer tuaj yeem hloov kho kom txiav nws tus cwj pwm txawv.
3. Synthesis thiab Kev Hloov Kho: nyob ntawm cov khoom uas xav tau, cov polymer yuav ua rau cov qauv zoo los yog ua kom tiav cov qauv molecular xav tau. Piv txwv li, CMC tuaj yeem ua tau zoo sib xws los ntawm reacting cellulose nrog chloroacetic acid nyob rau hauv Alkaline tej yam kev mob. Cov qib ntawm qhov hloov pauv (DS), uas txiav txim siab tus lej ntawm cov cargoxymethyl ib pawg, tuaj yeem tswj hwm lub zog polymeres, tuaj yeem tswj hwm lub solubility, viscosity, thiab thickening efficiency.
4. Tsim kom zoo dua: lub rheatoral xum yog txuas rau cov qauv ntawm qhov tsim nyog kom ua tiav qhov xav tau thiab kev xav tsis sib haum xeeb. Daim qauv kev ua kom zoo yuav muaj kev kho kom haum rau cov ntsiab lus polymer, Phy, tus nqi ntsev kom ua tau zoo rau kev ua kom muaj kev ruaj khov thiab kev ruaj khov.
5. Kev sim tshuaj ntsuam: Cov khoom lag luam raug kuaj kom ntsuas nws cov khoom siv nrawm nyob rau ntau yam uas cuam tshuam rau cov ntawv thov. Qhov no suav nrog kev ntsuas ntawm viscosity, shear viscosity profiles, tawm tsam kev ntxhov siab, thixotrostropy, thiab ruaj khov nyob rau lub sijhawm. Kev sim ua kom paub meej tias lub rhe rheological thickener ua tau raws li cov kev cai tshwj xeeb thiab ua rau muaj kev ntseeg siab.
6. Nplai-nce thiab kev tsim khoom: Thaum tsim tau zoo thiab ua tau zoo siv, cov txheej txheem ntau lawm yog ua rau kev lag luam lag luam. Yam xws li batch-to-batch-to-batch-batch-to-batch xwm yeem, thiab nqi-ua hauj lwm ruaj khov thiab kev lag luam zoo heev ntawm cov khoom.
7. Kev Txhim Kho Nrov: Kev tsim kho ntawm cov txheej txheem tuab yog ib cov txheej txheem txuas ntxiv uas yuav ua rau kev txhim kho txuas ntxiv raws li cov lus pom zoo, thiab hloov pauv hauv kev lag luam xav tau. Cov qauv ua tau zoo yuav yog kho kom zoo nkauj, thiab cov thev naus laus zis tshiab lossis cov ntxiv yuav tau sib xyaw los txhim kho kev ua tau zoo, muaj kev ua tau zoo, thiab tus nqi ua haujlwm tau zoo.

Zuag qhia tag nrho, kev txhim kho ntawm rheological thickeners muaj cov kev tshawb fawb txog kev ua haujlwm polymer, thiab kev sim ua kom muaj raws li cov kev siv ntau yam ntawm cov ntawv thov sib txawv.
