Puas yog HPMC 200000 viscosity suav tias yog siab viscosity?

Yog lawm, Hydroxypropyl Methylcellulose (HPMC) nrog viscosity ntawm 200,000 mPa·s (millipascal-seconds) feem ntau suav hais tias muaj viscosity siab. Viscosity yog ib qho kev ntsuas ntawm cov kua dej tsis kam ntws, thiab HPMC nrog lub viscosity ntawm 200,000 mPa·s yuav muaj kev tiv thaiv siab heev rau kev ntws piv rau cov qib viscosity qis.

HPMC muaj nyob rau hauv ntau hom viscosity qib, feem ntau yog li ntawm 5,000 mPa·s txog 200,000 mPa·s lossis siab dua. Cov qib viscosity tshwj xeeb xav tau rau ib daim ntawv thov tshwj xeeb yog nyob ntawm cov yam ntxwv xws li cov khoom xav tau rheological, daim ntawv thov txheej txheem, cov txheej txheem substrate, thiab cov kev xav tau ua haujlwm.

Feem ntau, cov qib viscosity siab dua ntawm HPMC feem ntau yog siv rau hauv cov ntawv thov uas xav tau qhov sib xws los yog cov dej khaws cia ntau dua, xws li cov khoom siv thickening, coatings, adhesives, thiab cement-based khoom. Cov qib siab viscosity no muab kev ua haujlwm zoo dua qub, txhim kho kev ua haujlwm, thiab txhim kho kev ua tau zoo hauv kev siv ntsug lossis nyiaj siv ua haujlwm.

Nws yog ib qho tsim nyog sau cia tias viscosity ib leeg tsis tuaj yeem txiav txim siab qhov tsim nyog ntawm HPMC rau ib daim ntawv thov tshwj xeeb, thiab lwm yam xws li particle loj faib, purity, thiab cov khoom siv tshuaj lom neeg kuj tuaj yeem ua lub luag haujlwm. Nws yog ib qho tseem ceeb uas yuav tau xav txog txhua yam tseem ceeb thiab sab laj txog cov khoom lag luam tshwj xeeb thiab cov ntaub ntawv qhia kev paub thaum xaiv cov qib viscosity tsim nyog ntawm HPMC rau ib qho kev tsim lossis daim ntawv thov.
