Qhov piv ntawm kev siv hydroxyethyl cellulose yog dab tsi?

Hydroxyethyl Cellulose (HEC) yog ib qho thickener, emulsifier thiab stabilizer uas siv ntau, siv dav hauv cov tshuaj pleev ib ce, tshuaj pleev ib ce, tshuaj ntxuav tes, cov ntaub ntawv tsim kho thiab lwm yam teb. Nws qhov kev siv piv feem ntau yog txiav txim siab raws li qhov xwm txheej thov tshwj xeeb thiab cov qauv xav tau.

1. Kev Lag Luam Txheej Txheem
Hauv cov txheej txheej uas muaj dej, hydroxyethyl cellulose feem ntau siv los ua cov khoom ua kom tuab thiab cov khoom dai kom pab kho qhov viscosity thiab rheology ntawm cov txheej txheej. Feem ntau, qhov piv ntawm kev siv yog 0.1% txog 2.0% (qhov hnyav piv). Qhov piv tshwj xeeb nyob ntawm hom txheej txheej, cov khoom rheological xav tau thiab kev sib xyaw ua ke ntawm lwm cov khoom xyaw.

2. Cov tshuaj pleev ib ce thiab cov khoom siv tu tus kheej
Hauv cov tshuaj pleev ib ce, hydroxyethyl cellulose yog siv los ua cov khoom tuab thiab stabilizer los pab txhim kho cov qauv thiab kev ua haujlwm ntawm cov khoom. Qhov piv txwv siv feem ntau yog 0.1% txog 1.0%. Piv txwv li, hauv tshuaj zawv plaub hau, tshuaj ntxuav ntsej muag, tshuaj pleev thiab gel, HEC tuaj yeem muab kev kov zoo thiab kev ruaj khov.

3. Cov tshuaj ntxuav thiab cov tshuaj ntxuav tes
Hauv cov tshuaj ntxuav kua, hydroxyethyl cellulose yog siv los kho qhov viscosity thiab kev ncua ntawm cov khoom thiab tiv thaiv kom tsis txhob muaj cov khoom khov. Qhov piv ntawm kev siv feem ntau yog 0.2% txog 1.0%. Tus nqi ntawm HEC siv rau hauv ntau hom khoom ntxuav yuav txawv.

4. Cov ntaub ntawv siv hauv tsev
Hauv cov ntaub ntawv siv hauv tsev, xws li cov cement slurry, gypsum, vuas nplaum, thiab lwm yam, hydroxyethyl cellulose yog siv los ua cov dej khaws cia thiab cov khoom tuab. Feem ntau, qhov piv txwv siv yog 0.1% txog 0.5%. HEC tuaj yeem txhim kho kev ua tau zoo ntawm cov khoom siv, txuas ntxiv lub sijhawm ua haujlwm, thiab txhim kho cov khoom tiv thaiv kev sagging.

5. Lwm yam kev siv
Hydroxyethyl cellulose kuj siv dav hauv lwm qhov chaw, xws li zaub mov thiab tshuaj. Feem ntau, qhov piv ntawm kev siv yog kho raws li qhov xav tau ntawm daim ntawv thov. Piv txwv li, hauv kev lag luam zaub mov, HEC tuaj yeem siv ua cov khoom siv tuab, stabilizer thiab emulsifier, thiab nws cov kev siv feem ntau yog qis heev.

Cov kev ceev faj
Thaum siv hydroxyethyl cellulose, koj yuav tsum tau them sai sai rau cov ntsiab lus hauv qab no:

Txoj kev yaj: Qhov solubility ntawm HEC yog cuam tshuam los ntawm qhov kub thiab txias, pH tus nqi thiab cov xwm txheej stirring. Nws feem ntau yuav tsum tau ntxiv qeeb qeeb rau hauv dej thiab do kom huv si.
Kev sib raug zoo ntawm cov mis: Cov khoom xyaw sib txawv ntawm cov mis yuav cuam tshuam rau kev ua haujlwm ntawm HEC, yog li kev sim sib raug zoo yog qhov yuav tsum tau ua thaum lub sijhawm tsim cov mis.
Kev tswj hwm viscosity: Raws li qhov xav tau ntawm cov khoom kawg, xaiv hom HEC thiab koob tshuaj kom haum rau qhov viscosity xav tau.
Qhov piv ntawm kev siv hydroxyethyl cellulose yog ib qho parameter uas yuav tsum tau hloov kho raws li daim ntawv thov thiab cov qauv tshwj xeeb. Kev nkag siab txog kev ua tau zoo ntawm HEC hauv ntau daim ntawv thov tuaj yeem pab txhim kho cov khoom ua tau zoo thiab zoo.
