Carbomer 980 nrog CAS 54182-57-9 Karbomer
Carbomer yog xoob dawb hmoov, nrog acidity, hygroscopicity thiab tshwj xeeb tsw tsw. Nws tuaj yeem yaj hauv dej, ethanol thiab glycerol. Cov molecule muaj 56% - 58% carboxyl pawg, yog li nws tsis muaj zog acidic. Thaum carbomer dispersed nyob rau hauv dej, vim lub repulsion ntawm cov nqi tsis zoo los ntawm carboxyl ionization, cov crimped polymer stretches tawm thiab nthuav nyob rau hauv ntim. pH ntawm 0.5% aqueous dispersion yog 2.7 ~ 3.5. 1% aqueous dispersion tuaj yeem nruab nrab nrog cov tshuaj alkaline los tsim cov gel. Cov 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.In tshuaj, nws tuaj yeem siv los ua tus neeg sawv cev gel, nplaum, cov khoom siv txheej, rheological modifier (humidifier, lubricant, suspension aid, stabilizer), thiab lwm yam, thiab yog siv dav, tshwj xeeb tshaj yog nyob rau hauv cov 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 hais tias tus thawj Carbomer 940 yog synthesized los ntawm acrylic acid thiab benzene, nws muaj ib tug npaum li cas ntawm benzene residue, uas yog ib tug tshuaj lom.
Yuav kom muaj kev nyab xeeb dua, peb siv cyclohexane los ua Carbomer 980, kom peb cov khoom xyaw yuav muaj kev nyab xeeb thiab cov nyhuv yuav zoo dua.
Tau kawg, Carbomer 980 yog tib yam li Carbomer 940 nyob rau hauv cov nqe lus ntawm viscosity thiab lub teeb transmittance.
Yog tias koj tsis muaj cov kev cai tshwj xeeb ntawm lub teeb xa tawm thiab viscosity, peb kuj pom zoo rau Carbomer 680, tus nqi yuav pheej yig dua.
