Kev faib tawm ntawm Methyl Cellulose Cov Khoom

Methyl cellulose (MC) cov khoom tuaj yeem raug cais raws li ntau yam xws li lawv qib viscosity, qib kev hloov pauv (DS), qhov hnyav molecular, thiab daim ntawv thov. Nov yog qee qhov kev faib tawm ntawm cov khoom methyl cellulose:

1. Qib viscosity:
   • Cov khoom lag luam methyl cellulose feem ntau tau muab cais raws li lawv cov qib viscosity, uas sib haum rau lawv cov viscosity hauv cov tshuaj aqueous. Lub viscosity ntawm methyl cellulose daws yog feem ntau ntsuas nyob rau hauv centipoise (cP) ntawm ib tug tshwj xeeb concentration thiab kub. Cov qib viscosity feem ntau suav nrog qis viscosity (LV), nruab nrab viscosity (MV), siab viscosity (HV), thiab ultra-high viscosity (UHV).
2. Degree of Hloov (DS):
   • Cov khoom lag luam methyl cellulose kuj tuaj yeem raug cais raws li lawv qhov kev hloov pauv, uas yog hais txog qhov nruab nrab ntawm cov pawg hydroxyl ib chav tsev piam thaj uas tau hloov nrog methyl pawg. Cov txiaj ntsig DS siab dua qhia tau tias muaj kev hloov pauv ntau dua thiab feem ntau ua rau muaj kev solubility ntau dua thiab qis dua gelation.
3. Molecular Luj:
   • Methyl cellulose cov khoom tuaj yeem sib txawv hauv qhov hnyav molecular, uas tuaj yeem cuam tshuam lawv cov khoom xws li solubility, viscosity, thiab gelation cwj pwm. Cov khoom hnyav dua molecular methyl cellulose zoo li muaj viscosity ntau dua thiab muaj zog gelling zog piv rau cov khoom hnyav dua molecular.
4. Daim ntawv thov-Specific Qib:
   • Cov khoom lag luam methyl cellulose kuj tuaj yeem raug cais raws li lawv cov ntawv thov. Piv txwv li, muaj cov qib tshwj xeeb ntawm methyl cellulose optimized rau cov tshuaj formulations, khoom noj khoom haus, cov ntaub ntawv siv, khoom tu tus kheej, thiab lwm yam kev siv. Cov qhab nia no tuaj yeem muaj cov khoom tsim nyog kom ua tau raws li qhov yuav tsum tau ua ntawm lawv cov ntawv thov.
5. Cov Qib Tshwj Xeeb:
   • Qee cov khoom lag luam methyl cellulose yog tsim los rau cov ntawv tshwj xeeb lossis muaj cov khoom tshwj xeeb tsim rau kev siv tshwj xeeb. Piv txwv suav nrog methyl cellulose derivatives nrog kev txhim kho thermal stability, txhim kho cov dej tuav, tswj cov yam ntxwv, los yog kev sib raug zoo nrog qee yam additives lossis cov kuab tshuaj.
6. Lub npe lag luam thiab hom:
   • Cov khoom lag luam methyl cellulose tuaj yeem ua lag luam raws li cov npe lag luam sib txawv lossis cov npe los ntawm ntau lub tuam txhab. Cov khoom no tej zaum yuav muaj cov khoom zoo sib xws tab sis yuav txawv ntawm cov specifications, zoo, thiab kev ua tau zoo. Cov npe lag luam feem ntau rau methyl cellulose suav nrog Methocel®, Cellulose Methyl, thiab Walocel®.

Cov khoom lag luam methyl cellulose tuaj yeem muab faib ua raws li qib viscosity, qib kev hloov pauv, qhov hnyav molecular, cov ntawv thov tshwj xeeb, qib tshwj xeeb, thiab cov npe lag luam. Kev nkag siab txog cov kev faib tawm no tuaj yeem pab cov neeg siv xaiv cov khoom tsim nyog methyl cellulose rau lawv cov kev xav tau tshwj xeeb thiab kev siv.
