HEC-100000

HEC-100000 yog hais txog Hydroxyethyl Cellulose (HEC) nrog viscosity specification ntawm 100,000 mPa·s (millipascal-seconds) los yog centipoise (cP) ntawm ib tug tshwj xeeb concentration thiab kub. HEC yog non-ionic, dej-soluble polymer muab los ntawm cellulose thiab feem ntau yog siv los ua cov thickening thiab gelling tus neeg sawv cev hauv ntau daim ntawv thov.

1. Hydroxyethyl Cellulose (HEC): HEC yog cellulose derivative hloov nrog hydroxyethyl pawg. Nws yog synthesized los ntawm cov tshuaj tiv thaiv ntawm cellulose nrog ethylene oxide, ua rau ib tug dej-soluble polymer nrog tshwj xeeb rheological zog.

2. Viscosity Specification: Tus lej "100,000" qhia qhov viscosity ntawm cov tshuaj HEC hauv millipascal-seconds (mPa·s) lossis centipoise (cP). Viscosity yog hais txog qhov tsis kam ntawm cov kua ntws, thiab nws yog ntsuas raws li lub zog xav tau kom txav ib txheej ntawm cov kua dej dhau mus rau lwm qhov. Nyob rau hauv cov ntaub ntawv no, viscosity specification ntawm 100,000 mPa·s los yog cP qhia lub thickness los yog sib xws ntawm cov tshuaj HEC ntawm ib tug tshwj xeeb concentration thiab kub.

3. Daim ntawv thov: HEC nrog viscosity specification ntawm 100,000 mPa·s raug suav hais tias muaj viscosity siab. Nws yog feem ntau siv los ua cov thickening, stabilizing, lossis gelling tus neeg sawv cev hauv ntau qhov kev lag luam, suav nrog:

• Xim thiab coatings
• Adhesives
• Cov khoom siv tu tus kheej (xws li, tshuaj zawv plaub hau, tshuaj pleev ib ce, thiab cream)
• Pharmaceutical formulations
• Cov ntaub ntawv tsim kho (xws li grouts, mortars, thiab pobzeb adhesives)

4. Formulation Considerations: Lub viscosity ntawm HEC tuaj yeem sib txawv nyob ntawm seb muaj ntau yam xws li concentration, kub, thiab shear npaum li cas. Cov neeg tsim khoom tuaj yeem teev cov nqi viscosity ntawm cov txheej txheem rau kev sib xws thiab kev tswj kom zoo. Thaum tsim cov khoom siv HEC-100000, nws yog ib qho tseem ceeb uas yuav tsum xav txog nws qhov kev sib raug zoo nrog lwm cov khoom xyaw, kev ua haujlwm, thiab qhov xav tau rheological zog ntawm cov khoom kawg.

Hauv cov ntsiab lus, HEC-100000 yog hais txog Hydroxyethyl Cellulose nrog viscosity specification ntawm 100,000 mPa·s lossis cP. Nws yog cov viscosity siab polymer feem ntau siv los ua cov thickening thiab gelling tus neeg sawv cev hauv ntau daim ntawv thov kev lag luam thiab cov neeg siv khoom.
