1. Nkag siab Rheology hauv Paints thiab Coatings:
   • Rheology hais txog kev kawm txog kev ntws thiab deformation tus cwj pwm ntawm cov ntaub ntawv hauv kev ntxhov siab.
   • Nyob rau hauv cov xim thiab txheej, rheological zog dictate yam xws li viscosity, thixotropy, leveling, sag resistance, thiab daim ntawv thov yam ntxwv.
   • Kev tswj kom zoo rheological yog qhov tseem ceeb rau kev ua tiav qhov xav tau, theem, thiab zaj duab xis tuab thaum thov, nrog rau kev tiv thaiv cov teeb meem xws li poob los yog sagging.
2. Lub luag haujlwm ntawm Cellulose Ethers hauv Rheology Hloov Kho:
   • Cellulose ethers ua hauj lwm raws li ntau yam rheology modifiers vim lawv muaj peev xwm cuam tshuam nrog dej molecules thiab tsim viscoelastic daws.
   • Lawv qhia tus cwj pwm shear-thinning, qhov twg viscosity txo qis hauv kev nyuaj siab shear, ua kom yooj yim thov thiab txhuam zoo.
   • Tsis tas li ntawd, cellulose ethers muab pseudoplasticity, lub ntsiab lus viscosity txo nrog nce shear npaum li cas, kom ntseeg tau tias cov dej ntws zoo thiab kev tiv thaiv ib puag ncig.
3. KimaCell® Cellulose Ethers: Kev Ntseeg thiab Kev Ua Haujlwm:
   • KimaCell® cellulose ethers tau tsim tshwj xeeb rau cov xim pleev xim thiab pleev xim, muab kev ua haujlwm zoo thiab txhim khu kev qha.
   • Cov cellulose ethers tuaj nyob rau hauv ntau qib, tso cai rau cov formulators kom zoo-tune viscosity thiab rheological zog kom tau raws li cov kev cai formulation.
   • KimaCell® cov khoom nthuav tawm cov dej tuav tau zoo, txhim kho cov xim ruaj khov thiab ua kom lub sijhawm qhib ntev yam tsis muaj kev cuam tshuam viscosity lossis zaj duab xis ncaj ncees.
   • Kev sib xyaw ua ke ntawm KimaCell® cellulose ethers nrog rau lwm cov xim pleev xim ua kom muaj kev sib xyaw ua ke rau hauv cov qauv tsim, pab txhawb rau tag nrho cov qauv kev ruaj ntseg thiab kev ua haujlwm.
4. Daim Ntawv Thov Cheeb Tsam thiab Cov txiaj ntsig:
   • Sab hauv thiab Sab Nraud Xim Xim: KimaCell® cellulose ethers txhim kho ntws thiab theem, txo splattering, thiab txhim khu kev txhuam, ua rau cov txheej txheej tuab thiab zoo kawg nkaus ua tiav.
   • Textured Coatings: Cov additives no ua rau muaj kev tswj xyuas meej ntawm kev ntxhib los mos profile, kom ntseeg tau tias muaj kev sib faib ntawm cov khoom thiab txhim kho adhesion rau substrates.
   • Primers thiab Sealers: KimaCell® cellulose ethers pab txhawb kev tsim cov yeeb yaj kiab zoo, txhim kho substrate wetting, thiab txhim kho intercoat adhesion hauv primer thiab sealer formulations.
   • Cov Txheej Txheem Tshwj Xeeb: Txawm hais tias nws yog cov qauv qis-VOC, cov txheej txheem tsim siab, lossis cov txheej txheem tshwj xeeb, KimaCell® cellulose ethers muab cov kev daws teeb meem rheological kom tau raws li ntau yam kev xav tau.
5. Formulation Guidelines and Considerations:
   • Kev Xaiv Qib: Cov qauv tsim yuav tsum xaiv cov qib tsim nyog ntawm KimaCell® cellulose ethers raws li qhov xav tau viscosity, rheological profile, thiab cov ntawv thov.
   • Compatibility Testing: Compatibility nrog rau lwm yam additives thiab raw khoom yuav tsum tau soj ntsuam xyuas kom ruaj khov thiab kev ua tau zoo nyob rau hauv lub kawg formulation.
   • Optimal Concentration: Qhov zoo tshaj plaws concentration ntawm cellulose ethers yuav tsum tau txiav txim los ntawm formulation optimization thiab kev ntsuam xyuas kom ua tau raws li qhov xav tau rheological zog.
   • Kev Tswj Xyuas Zoo: Kev tswj xyuas nruj nruj yuav tsum tau ua kom muaj kev sib luag thiab kev ntseeg siab hauv cov xim pleev xim uas muaj KimaCell® cellulose ethers.

Xaus: KimaCell® cellulose ethers sawv tawm raws li kev txhim khu kev qha rheology kev daws teeb meem rau cov xim thiab txheej txheej, muab kev ua tau zoo sib xws, ntau yam, thiab yooj yim ntawm kev tsim. Lawv lub peev xwm los txhim kho kev khiav, theem, kev tswj kev ntxhib los mos, thiab kev ruaj ntseg ua rau lawv cov khoom siv tsis tseem ceeb rau kev ua tiav cov txheej txheem uas xav tau thiab ua kom cov khoom zoo kawg nkaus. Raws li qhov kev thov rau cov txheej txheem kev ua haujlwm siab thiab ib puag ncig tus phooj ywg txuas ntxiv nce ntxiv, KimaCell® cellulose ethers tseem nyob rau hauv pem hauv ntej, tsav kev tsim kho tshiab thiab ua tau zoo hauv kev lag luam xim thiab txheej txheej.
