Cellulose ether hmoov yog ib qho uas nquag siv thickener hauv kev tsim kho kev lag luam.Nws yog siv rau hauv cov ntaub ntawv cementitious xws li mortar, stucco thiab pobzeb adhesives.Kev siv kom raug thiab muaj txiaj ntsig zoo ntawm cov cellulose ether hmoov yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab sib xws ntawm cov khoom kawg.
Nov yog qee yam tseem ceeb uas yuav tsum tau xav txog thaum muab cov cellulose ether hmoov:
1. Dej zoo: Qhov zoo ntawm cov dej siv hauv cov txheej txheem kev sib cais tuaj yeem cuam tshuam rau cov txiaj ntsig ntawm cellulose ether hmoov.Cov dej hardness siab lossis siab impurity tuaj yeem cuam tshuam tsis zoo rau solubility ntawm cov hmoov.Yog li ntawd, kev siv cov dej huv, cov dej zoo yog qhov tseem ceeb los xyuas kom meej qhov zoo ntawm cov cellulose ether hmoov.
2. Txoj kev sib tov: Txoj kev sib tov kuj tseem ua lub luag haujlwm tseem ceeb hauv kev sib cais.Cov hmoov yuav tsum tau ntxiv maj mam thaum nplawm tas li kom tsis txhob muaj cov pob thiab xyuas kom zoo.Lub tshuab tov khoom raug pom zoo, tshwj xeeb tshaj yog rau cov haujlwm loj lossis thaum tawg cov hmoov ntau.
3. Kub: Qhov kub ntawm cov dej uas siv rau hauv cov txheej txheem dissolution kuj yuav cuam tshuam rau solubility ntawm cellulose ether hmoov.Feem ntau, cov dej sov yog nyiam dua vim nws pab ua kom cov txheej txheem tawg thiab ua kom zoo dua sib xyaw thiab tawg ntawm cov hmoov.Txawm li cas los xij, dej kub yuav tsum tau zam vim nws tuaj yeem ua rau cov hmoov gel thiab tsim cov clumps.
4. Cia: Kev cia kom zoo ntawm cellulose ether hmoov yog qhov tseem ceeb los tswj nws qhov zoo thiab ua haujlwm zoo.Cov hmoov yuav tsum muab cia rau hauv qhov chaw txias, qhuav, zoo-ventilated qhov chaw tawm ntawm tshav ntuj ncaj qha.Cov dej noo tuaj yeem ua rau cov hmoov txhuam thiab poob nws cov txiaj ntsig.Yog li ntawd, nws raug nquahu kom khaws cov hmoov hauv ib lub thawv airtight.
5. Kev Dispersion Zoo: Kev faib tawm ntawm cellulose ether hmoov yog qhov tseem ceeb rau nws cov txiaj ntsig.Ua tib zoo dispersing cov hmoov nyob rau hauv qhov sib tov kom ntseeg tau tias nws yog tusyees faib, uas ua rau kom zoo ib yam thiab txhim kho kev ua tau zoo.Qhov no tuaj yeem ua tiav los ntawm kev ntxiv cov hmoov maj mam thaum nplawm tas li thiab tso sijhawm txaus rau cov hmoov kom yaj tag.
6. Dosage: Qhov ntau npaum ntawm cellulose ether hmoov sib txawv raws li daim ntawv thov tshwj xeeb thiab qhov yuav tsum tau ua kom sib xws ntawm cov khoom sib xyaw.Nws yog ib qho tseem ceeb uas yuav tsum tau siv cov tshuaj kom raug raws li kev pom zoo los ntawm cov chaw tsim khoom kom tsis txhob muaj kev phom sij.Ntxiv cov hmoov ntau dhau los yog tsawg dhau tuaj yeem ua rau qhov tsis zoo xws li poob lub zog, kev sib txuas tsis zoo lossis tawg.
7. Compatibility: Cellulose ether hmoov tej zaum yuav tsis haum rau tej yam ntaub ntawv, xws li acrylic-based systems.Nws yog ib qho tseem ceeb heev uas yuav tsum tau kuaj xyuas cov hmoov sib xyaw nrog lwm cov ntaub ntawv hauv qhov sib tov ua ntej siv.Kev sim ua ntej rau kev sib raug zoo pab kom tsis txhob muaj teeb meem muaj peev xwm thiab ua kom ntseeg tau tias qhov sib tov ua tiav cov khoom xav tau.
Hauv cov ntsiab lus, kev ua kom zoo ntawm cov cellulose ether hmoov yog qhov tseem ceeb los xyuas kom meej qhov zoo thiab sib xws ntawm cov khoom siv cement.Ua tib zoo saib xyuas cov dej zoo, kev sib xyaw ua ke, qhov kub thiab txias, khaws cia, dispersion kom zoo, ntau npaum li cas thiab kev sib raug zoo tuaj yeem pab ua tiav cov txiaj ntsig xav tau.Los ntawm kev ua raws li cov lus qhia no, cov neeg cog lus tuaj yeem paub tseeb tias lawv siv cellulose ether hmoov zoo thiab muaj txiaj ntsig.
