Hydroxyethyl Cellulose CAS 9004-62-0
Hydroxyethyl cellulose yog xim dawb mus rau lub teeb daj daj lossis hmoov hmoov, tsis muaj tshuaj lom, tsis qab, thiab yooj yim soluble hauv dej. Nws yog insoluble nyob rau hauv cov organic solvents. Nws muaj cov yam ntxwv ntawm thickening, suspending, bonding, emulsifying, dispersing, thiab khaws cia noo noo. Cov kev daws teeb meem nrog cov viscosity sib txawv tuaj yeem npaj tau. Nws muaj qhov tshwj xeeb zoo ntsev solubility hauv electrolytes. Hydroxyethyl cellulose yog cov hmoov dawb los yog lub teeb daj uas tsis muaj ntxhiab, tsis qab, thiab yooj yim-ntws hmoov. Nws yog soluble nyob rau hauv ob qho tib si dej txias thiab kub, thiab feem ntau insoluble nyob rau hauv feem ntau cov organic solvents. Lub viscosity hloov me ntsis thaum pH tus nqi nyob rau hauv thaj tsam ntawm 2-12, tab sis lub viscosity txo qis tshaj qhov no.

1. Hydroxyethyl cellulose (HEC) yog ib qho uas tsis yog-ionic soluble cellulose ether nrog zoo thickening, ncua kev kawm ntawv, dispersion, emulsification, adhesion, zaj duab xis tsim, tiv thaiv noo noo thiab tiv thaiv colloid zog. Vim nws lub cev thiab tshuaj lom neeg tshwj xeeb, HEC tau siv dav hauv ntau lub teb, suav nrog tab sis tsis txwv rau kev rho tawm roj, txheej txheej, kev tsim kho, khoom noj khoom haus, textiles, papermaking thiab polymerization.
2. Hauv kev lag luam tshuaj, ntxiv rau kev ua cov thickener thiab tiv thaiv tus neeg sawv cev, hydroxyethyl cellulose kuj muaj cov nyhuv moisturizing, hydrating, tiv thaiv kev laus, ntxuav ntawm daim tawv nqaij, thiab tshem tawm melanin. Nws yog qhov tsim nyog rau kev ua qhov muag tee, tshuaj tsuag qhov ntswg, tshuaj hauv qhov ncauj, thiab lwm yam. Nws tuaj yeem ua kom cov viscosity ntawm cov tshuaj, txhim kho qhov nqus ntawm cov tshuaj hauv lub cev, thiab ua kom cov tshuaj ruaj khov los tiv thaiv cov tshuaj decomposition thiab oxidation.
3. Hauv kev lag luam tshuaj pleev ib ce, HEC tau siv dav hauv kev tsim cov tshuaj zawv plaub hau, tshuaj pleev, tshuaj pleev, tshuaj pleev thiab lwm yam khoom. Nws tuaj yeem kho cov viscosity thiab kev ntxhib los mos ntawm cov tshuaj pleev ib ce kom yooj yim rau kev thov thiab nqus. Nyob rau tib lub sijhawm, nws kuj muaj cov nyhuv moisturizing, tuaj yeem kaw cov dej noo, thiab tiv thaiv cov tawv nqaij qhuav thiab tawg.
4. Tsis tas li ntawd, hydroxyethyl cellulose feem ntau yog siv los ua cov thickener, colorant thiab preservative nyob rau hauv cov zaub mov kev lag luam, uas yuav ua rau kom lub viscosity thiab zoo nkauj ntawm cov zaub mov thiab txhim kho cov saj thiab zoo ntawm cov zaub mov. Nws kuj tseem siv tau los ua emulsifier thiab stabilizer los tiv thaiv zaub mov stratification thiab nag lossis daus.
5. Hais txog acidity thiab alkalinity ntawm hydroxyethyl cellulose, vim nws belongs rau cov chav kawm ntawv uas tsis yog-ionic cellulose ether, nws tsis yog acidic los yog alkaline. Nws cov tshuaj formula yog (C2H6O2)n, nrog zoo solubility, stability thiab thickening zog, thiab plays lub luag hauj lwm tseem ceeb nyob rau hauv ntau yam ntawm daim ntawv thov teb.
