Tswv yim Rau Hydrating Hydroxyethyl Cellulose (HEC)

Hydroxyethyl cellulose (HEC) yog cov dej-soluble polymer feem ntau siv nyob rau hauv ntau yam lag luam rau nws cov thickening, stabilizing, thiab zaj duab xis-forming zog. Thaum ua haujlwm nrog HEC, ua kom muaj dej kom zoo yog qhov tseem ceeb kom ua tiav qhov kev xav tau hauv cov qauv. Nov yog qee cov lus qhia rau hydrating HEC kom zoo:

1. Siv Dej Distilled: Pib los ntawm kev siv dej distilled lossis dej deionized rau hydrating HEC. Cov impurities lossis ions tam sim no hauv cov kais dej tuaj yeem cuam tshuam cov txheej txheem hydration thiab tuaj yeem ua rau cov txiaj ntsig tsis sib xws.
2. Txoj Kev Npaj: Muaj ntau txoj hauv kev rau hydrating HEC, suav nrog kev sib xyaw txias thiab kub sib tov. Hauv kev sib xyaw txias, HEC yog maj mam ntxiv rau hauv dej nrog txuas ntxiv mus kom txog thaum tag nrho dispersed. Kev sib xyaw kub yog ua kom sov cov dej mus rau ib ncig ntawm 80-90 ° C thiab maj mam ntxiv HEC thaum nplawm kom txog thaum muaj dej txaus. Qhov kev xaiv ntawm txoj kev yog nyob ntawm cov kev cai tshwj xeeb ntawm kev tsim.
3. Ntxiv Ntxiv: Txawm hais tias siv qhov sib xyaw txias lossis kub sib tov, nws yog qhov tseem ceeb kom ntxiv HEC maj mam rau hauv dej thaum nplawm tas li. Qhov no pab tiv thaiv kev tsim cov pob thiab ua kom cov khoom sib txawv ntawm cov khoom polymer.
4. stirring: Tsim nyog stirring yog ib qho tseem ceeb rau hydrating HEC zoo. Siv lub tshuab stirrer los yog high-shear tov khoom los xyuas kom meej dispersion thiab hydration ntawm cov polymer. Tsis txhob siv kev ntxhov siab ntau dhau, vim nws tuaj yeem ua kom pom cov npuas hauv cov tshuaj.
5. Lub Sijhawm Dej: Cia sijhawm txaus rau HEC kom hydrate tag nrho. Nyob ntawm qib ntawm HEC thiab cov txheej txheem hydration siv, qhov no tuaj yeem nyob ntawm ob peb feeb mus rau ob peb teev. Ua raws li cov chaw tsim khoom cov lus pom zoo rau qib tshwj xeeb ntawm HEC siv.
6. Kev Tswj Kub Kub: Thaum siv cov khoom kub sib tov, saib xyuas qhov kub ntawm cov dej kom zoo kom tsis txhob muaj cua sov, uas tuaj yeem degrade cov polymer. Khaws cov dej kub hauv qhov kev pom zoo thoob plaws hauv cov txheej txheem hydration.
7. Kev kho pH: Hauv qee cov qauv, kho cov pH ntawm cov dej ua ntej ntxiv HEC tuaj yeem txhim kho cov dej. Tham nrog tus tsim qauv lossis xa mus rau cov khoom tshwj xeeb rau kev qhia txog kev hloov pH, yog tias tsim nyog.
8. Kev Ntsuas thiab Kev Kho Kom Zoo: Tom qab hydration, sim cov viscosity thiab sib xws ntawm HEC cov tshuaj kom ntseeg tau tias nws ua tau raws li qhov xav tau tshwj xeeb. Yog xav tau kev hloov kho, ntxiv dej los yog HEC tuaj yeem ntxiv maj mam thaum nplawm kom ua tiav cov khoom xav tau.

Los ntawm kev ua raws li cov lus qhia no, koj tuaj yeem ua kom muaj dej kom zoo ntawm hydroxyethyl cellulose (HEC) thiab ua kom nws qhov kev ua tau zoo hauv koj cov qauv.
