Carbomer 980 nrog CAS 54182-57-9 Karbomer
Carbomer yog ib hom hmoov dawb xoob, muaj kua qaub, hygroscopicity thiab tsw qab me ntsis. Nws tuaj yeem yaj rau hauv dej, ethanol thiab glycerol. Lub molecule muaj 56% - 58% carboxyl pawg, yog li nws tsis muaj zog acidic. Thaum carbomer raug dispersed hauv dej, vim yog qhov kev sib tsoo ntawm cov nqi tsis zoo los ntawm carboxyl ionization, cov polymer crimped ncab tawm thiab nthuav dav hauv ntim. Lub pH ntawm 0.5% aqueous dispersion yog 2.7 ~ 3.5. 1% aqueous dispersion tuaj yeem neutralized nrog alkaline tshuaj los ua gel. Lub concentration ntawm feem ntau siv aqueous dispersion yog 0.1% - 3.0%.

1. Lub luag haujlwm tseem ceeb ntawm carbomer yog thickening, suspension thiab emulsification,
2. Hauv kev lag luam tshuaj, nws tuaj yeem siv ua tus neeg sawv cev gel, nplaum, cov khoom siv txheej, rheological modifier (humidifier, roj nplua nyeem, suspension aid, stabilizer), thiab lwm yam, thiab siv dav, tshwj xeeb tshaj yog hauv cov txheej txheem xa tshuaj tshiab. Nws tau siv dav hauv tsev thiab txawv teb chaws.
Tam sim no, peb lub Hoobkas tau hloov kho carbomer 940 mus rau carbomer 980. Vim tias Carbomer 940 thawj yog tsim los ntawm acrylic acid thiab benzene, nws muaj qee qhov ntawm benzene residue, uas yog cov tshuaj lom.
Yuav kom muaj kev nyab xeeb dua, peb siv cyclohexane los ua Carbomer 980, yog li ntawd peb cov khoom xyaw yuav muaj kev nyab xeeb dua thiab cov txiaj ntsig yuav zoo dua.
Tau kawg, Carbomer 980 zoo ib yam li Carbomer 940 hais txog viscosity thiab lub teeb transmittance.
Yog tias koj tsis muaj qhov tshwj xeeb xav tau ntawm kev xa hluav taws xob thiab viscosity, peb kuj pom zoo Carbomer 680, tus nqi yuav pheej yig dua.
