Hydroxyethyl Cellulose yog dab tsi?

Hydroxyethyl cellulose yog ib hom khoom siv fibrous dawb mus rau daj daj los yog hmoov, tsis muaj tshuaj lom, tsis muaj saj, thiab yooj yim yaj hauv dej. Nws tsis yaj hauv cov organic solvents dav dav. Nws muaj cov yam ntxwv ntawm kev ua kom tuab, ncua, sib txuas, emulsifying, dispersing, thiab khaws cia noo noo. Cov tshuaj nrog ntau yam viscosity tuaj yeem npaj tau. Nws muaj kev yaj ntsev zoo heev hauv electrolytes. Hydroxyethyl cellulose yog ib hom hmoov dawb los yog daj daj tsis muaj ntxhiab, tsis muaj saj, thiab yooj yim ntws. Nws yaj hauv dej txias thiab dej kub, thiab feem ntau tsis yaj hauv feem ntau cov organic solvents. Lub viscosity hloov me ntsis thaum tus nqi pH nyob rau hauv qhov ntau ntawm 2-12, tab sis lub viscosity txo qis dhau qhov ntau ntawm no.

Daim Ntawv Thov

1. Hydroxyethyl cellulose (HEC) yog ib qho cellulose ether uas tsis yog ionic soluble nrog cov thickening, suspension, dispersion, emulsification, adhesion, film creation, moisture protection thiab protective colloid. Vim nws cov khoom siv lub cev thiab tshuaj tshwj xeeb, HEC siv dav hauv ntau qhov chaw, suav nrog tab sis tsis txwv rau kev rho tawm roj, coatings, kev tsim kho, tshuaj noj, textiles, papermaking thiab polymer polymerization.
2. Hauv kev lag luam tshuaj, ntxiv rau kev ua kom tuab thiab tiv thaiv kab mob, hydroxyethyl cellulose kuj muaj cov teebmeem ntawm kev ua kom noo noo, ua kom noo, tiv thaiv kev laus, ntxuav tawv nqaij, thiab tshem tawm melanin. Nws yog qhov tsim nyog rau kev ua cov tshuaj qhov muag, tshuaj tsuag qhov ntswg, cov tshuaj hauv qhov ncauj, thiab lwm yam. Nws tuaj yeem ua rau cov tshuaj viscosity nce ntxiv, txhim kho qhov nqus ntawm cov tshuaj hauv lub cev, thiab ua kom cov tshuaj ruaj khov dua los tiv thaiv kev lwj thiab oxidation ntawm cov tshuaj.
3. Hauv kev lag luam tshuaj pleev ib ce, HEC siv dav hauv kev tsim cov tshuaj zawv plaub hau, tshuaj pleev ib ce, tshuaj pleev ib ce, tshuaj pleev ib ce thiab lwm yam khoom. Nws tuaj yeem kho qhov viscosity thiab cov qauv ntawm cov tshuaj pleev ib ce kom yooj yim rau kev thov thiab nqus. Tib lub sijhawm, nws kuj muaj cov nyhuv moisturizing, tuaj yeem xauv cov dej noo, thiab tiv thaiv daim tawv nqaij qhuav thiab tawg.
4. Ntxiv rau, hydroxyethyl cellulose feem ntau yog siv los ua cov khoom ua kom tuab, xim thiab tshuaj tiv thaiv hauv kev lag luam zaub mov, uas tuaj yeem ua rau cov khoom noj muaj viscosity thiab cov qauv zoo dua thiab txhim kho cov saj thiab zoo ntawm cov khoom noj. Nws kuj tseem siv tau ua cov emulsifier thiab stabilizer los tiv thaiv cov khoom noj stratification thiab nag lossis daus.
5. Hais txog qhov acidity thiab alkalinity ntawm hydroxyethyl cellulose, vim nws yog ib feem ntawm cov non-ionic cellulose ether chav kawm, nws tsis yog acidic lossis alkaline. Nws cov mis tshuaj yog (C2H6O2) n, nrog cov khoom zoo solubility, stability thiab thickening, thiab ua lub luag haujlwm tseem ceeb hauv ntau yam kev siv.
