Dab tsi yog cov nyiaj ntawm hydroxyethyl cellulose ntxiv?

Hydroxyethyl cellulose (HEC) yog cov dej tsis-ionic-soluble polymer dav siv hauv cov tshuaj pleev ib ce, roj av, stabilizer, cov neeg sawv cev rau tus neeg sawv cev. Nws muaj cov nyhuv zoo heev, ntsev tsis kam, alkali tsis kam thiab zoo biodegradability. Hauv cov ntawv thov tiag tiag, tus nqi ntawm hydroxyethyl cellulose ntxiv yuav sib txawv raws li daim ntawv thov teb, siv ib puag ncig thiab yuav tsum tau ua.

Nyob rau hauv thaj teb ntawm cov tshuaj pleev ib ce, hydroxyethyl cellulose feem ntau siv los ua cov tuab thiab stabilizer. Piv txwv li, hauv cov khoom lag luam xws li lotions, gels, thiab ntsej muag huv, txhim kho cov khoom lag luam, txhim kho cov khoom lag luam, thiab tiv thaiv cov khoom los ntawm kev sib tsoo. Hauv qhov no, tus nqi ntawm hydroxyethyl cellulose ntxiv feem ntau yog nyob nruab nrab ntawm 0.1%, thiab cov nyiaj tshwj xeeb uas yuav tsum tau hloov kho raws li cov tshuaj tshwj xeeb thiab cov tseev kom muaj ntawm cov khoom lag luam. Yog tias yuav muaj viscosity lossis raug tshem tawm zoo ntxiv, tus nqi ntxiv yuav raug nce ntxiv; Yog hais tias qis viscosity yog xav tau, tus nqi yuav raug txo kom tsawg.

Hauv cov ntaub ntawv hauv tsev, hydroxyethyl cellulose feem ntau yog siv nyob rau hauv cov khoom xws li cementum cov ntaub ntawv, khaws cov hmoov av, txhim kho cov haujlwm ua haujlwm thiab nce cov khoom siv adhesion. Hauv cov ntawv thov zoo li no, tus nqi ntawm hydroxyethyl cellulose ntxiv feem ntau yog nyob nruab nrab ntawm 0.2% thiab 0.5%. Qhov nyiaj tsawg no yog txaus txhim kho cov khoom siv ua haujlwm tsis muaj cov khoom siv dhau los lossis cuam tshuam rau cov khoom siv zaum kawg. Hauv kev siv cov kev siv, cov nqi tshwj xeeb tseem yuav tsum tau hloov kho raws li cov ntaub ntawv muaj pes tsawg leeg, qhov kev tsim kho tsim nyog thiab ib puag ncig kev ua haujlwm.

Nyob rau hauv oilfield chement, hydroxyethyl cellulose yog siv los ua cov tshuaj tua hluav taws xob, ruaj khov rau cov dej zoo thiab tiv thaiv kom tsis txhob muaj cov kua lim. Hauv daim teb no, tus nqi ntawm hydroxyethyl cellulose ntxiv yog feem ntau ntawm 0.5% thiab 1.5%. Qhov nyiaj tiag tiag ntxiv yuav cuam tshuam los ntawm downhole tej yam kev mob (xws li qhov kub, thiab lwm yam), yog li nws yuav tsum tau hloov kho raws li qhov chaw tsim kho thiab cov kev tsim kho.

Nyob rau hauv cov txheej txheej kev lag luam, tus nqi ntxiv ntawm hydroxyethyl cellulose feem ntau ntawm 0.1% thiab 0.5%, nyob ntawm seb hom txheej thiab cov viscosity. Hauv cov txheej txheej hauv dej, hydroxyethyl cellulose tsis tsuas yog muab cov nyhuv thickening, tab sis kuj tseem ua kom zoo dua qub ntawm cov txheej txheem theem ntawm cov txheej txheem ntawm cov txheej. Hauv cov hmoov hmoov, hydroxyethyl cellulose tuaj yeem nce cov hmoov thiab ua kom yooj yim ntawm cov khoom tsim kho thiab qhov chaw zoo ntawm cov khoom tiav.

Tus nqi ntawm hydroxyethyl cellulose ntxiv yog nyob ntawm cov xwm txheej xws li nws cov kev xav tau ntawm cov ntaub ntawv tshwj xeeb, qhov yuav tsum muaj viscosity, thiab kev txiav txim siab txog kev txiav txim siab. Thaum tsim cov mis, nws yog feem ntau tsim nyog los txiav txim siab ntxiv cov nyiaj ntxiv nrog kev sim thiab kev paub ua tiav cov khoom lag luam uas xav tau. Txawm hais tias lub teb uas tsim nyog yuav tsis tsuas yog ua kom tau cov khoom lag luam zoo tshaj plaws, tab sis kuj tseem tswj tus nqi thiab txhim kho ntau dua. Hauv kev ua haujlwm tiag, cov kws tshaj lij yuav ua kom zoo dua cov nyiaj sib ntxiv raws li kev sim ua kom paub tseeb thiab ua tau zoo ntawm cov khoom lag luam kawg tau raws li cov qauv kev cia siab.
