   • Kev npaj cov ntsiab lus:Hauv cov tshuaj pleev ib ce zoo li gels, cream, thiab tshuaj pleev, Methocel HPMC E50 tuaj yeem ua haujlwm kom ua tiav cov khoom siv rheological uas xav tau, txhim kho qhov ruaj khov thiab siv cov yam ntxwv ntawm cov khoom.
2. Khoom siv:
   • Mortars thiab Cement:HPMC, suav nrog Methocel HPMC E50, yog siv nyob rau hauv kev tsim kho kev lag luam ua cov thickener thiab dej tuav tus neeg sawv cev. Nws txhim kho kev ua haujlwm, adhesion, thiab kev ua haujlwm tag nrho ntawm cov mortars thiab cov khoom siv cement.
3. Kev Siv Hluav Taws Xob:
   • Paints thiab Coatings:Methocel HPMC E50 tuaj yeem pom cov ntawv thov hauv kev tsim cov xim thiab cov txheej txheem. Nws cov viscosity-tswj zog pab txhawb rau qhov xav tau rheological yam ntxwv ntawm cov khoom no.

Kev txiav txim siab:

1. Compatibility:
   • Methocel HPMC E50 feem ntau sib xws nrog ntau yam ntawm lwm cov khoom xyaw siv hauv kev lag luam sib txawv. Txawm li cas los xij, kev ntsuas kev sib raug zoo yuav tsum tau ua hauv cov qauv tshwj xeeb kom ntseeg tau tias kev ua tau zoo.
2. Txoj Cai Ua Raws Cai:
   • Ib yam li cov khoom noj lossis cov khoom siv tshuaj, nws yog ib qho tseem ceeb los xyuas kom meej tias Methocel HPMC E50 ua raws li cov qauv kev cai thiab cov cai hauv daim ntawv thov.

Xaus:

Methocel HPMC E50, nrog nws qib siab viscosity, muaj nuj nqis rau nws lub peev xwm los tswj cov viscosity hauv ntau cov qauv. Nws daim ntawv thov nthuav dav thoob plaws cov chaw muag tshuaj, cov ntaub ntawv tsim kho, thiab cov qauv kev lag luam, qhov twg viscosity tswj thiab dej-solubility yog qhov tseem ceeb.
