Carbomer, tseem hu ua Carbomer, yog ib tug polymer tsim los ntawm cov tshuaj crosslinking ntawm acrylic acid los yog acrylate nrog allyl pawg ether, xws li polyacrylic acid (homopolymer) thiab ntev-chain alkanol acrylate polymer (copolymer). Nws cov qauv molecular muaj 52 ~ 68% acid pawg, yog li nws muaj qee yam acidity thiab hydrophilicity, thiab tuaj yeem yaj hauv dej, ethanol thiab glycerol.
Carbomer muaj zog xws li thickening, ncua kev kawm ntawv, stabilizing lub kaw lus, tswj kev tso dej thiab active tshuaj, thiab muaj cov txheej txheem yooj yim thiab zoo stability. Yog li ntawd, nws yog ib tug rheological hloov thickener lug siv nyob rau hauv cov khoom kho tus kheej, kws, thiab lwm yam teb.
Kev ua tau zoo thiab kev siv ntawm Kev Siv Carbomer Series
Nyob ntawm seb qhov kev sib txuas ntawm qhov sib txuas thiab qhov hnyav molecular, Capom muaj ntau hom khoom, nrog rau cov khoom siv xws li Carbopol 910, 934, 934 P, 940, 941, 954, thiab cov polymers tshiab xws li Carbopol Ultrez 20/21. . Vim qhov sib txawv ntawm kev ncua kev ruaj ntseg yam ntxwv, ntws hloov ntev, thiab lwm yam khoom ntawm cov qauv sib txawv ntawm Kapooms, lawv cov ntawv thov hauv ntau qhov kev lag luam kuj txawv. Cia peb saib ntawm qhov kev ua tau zoo thiab kev siv ntawm ntau cov carbomers feem ntau siv hauv cov tshuaj pleev ib ce.
Carbopol 940:
luv rheology, siab viscosity, siab clarity, tsawg ion kuj thiab shear kuj, haum rau gel thiab qab zib
Carbopol 941: Cov
Ntev rheology, tsawg viscosity, siab clarity, nruab nrab ion kuj thiab shear kuj, haum rau gel thiab pleev
Carbopol ETD 2020:
Acrylate / C10-30 alkyl acrylate hla saw copolymer, ntev rheological, tsis muaj viscosity, siab clarity, siab ion kuj thiab shear kuj, haum rau ntshiab gel.
Tom ntej: Carbopol AQUA SF-1
Kua, nrog ntev rheological zog, tuaj yeem tsim rau hauv cov qauv ntshiab, thiab muaj kev sib raug zoo nrog ntau yam khoom. Nws tuaj yeem siv rau hauv cov tshuab surfactant rau acid reflux thickening.
Carbopol Ultrez 21:
Acrylate / C10-30 alkyl acrylate cross chain copolymer, luv luv rheological, siv rau gel, ntxuav cov khoom, cov khoom siv electrolyte siab, qab zib, tshuaj pleev ib ce.
Carbopol Ultrez 20:
Acrylate / C10-30 alkyl acrylate cross chain copolymer, ntev rheology, tsuaj zawv plaub hau, da dej gel, cream / lotion, kev tu tawv nqaij nrog electrolyte, plaub hau tu gel
TR-1 Pulverizer:
Acrylate / C10-30 alkyl acrylate hla saw copolymer, thickened emulsifier, luv luv rheology, siv rau qab zib thiab tshuaj pleev ib ce
TR-2 Pulverizer:
Acrylate / C10-30 alkyl acrylate hla saw copolymer, thickened emulsifier, ntev rheological, siv rau pleev
Daim ntawv thov
Carbomer polymer emulsifiers yog superior rau emulsifiers
Ua tau zoo ntawm qhov tsis tshua muaj siab -0.1-0.5%, hloov cov tshuaj surfactant ib txwm siv ntawm 3-7%
Tsis txwv los ntawm HLB values and PlT
Muaj peev xwm emulsify tej kua roj ntawm chav tsev kub
Yog tias siv quav ciab tau yaj thaum lub sijhawm tsim khoom, nws tuaj yeem ua emulsified
Los ntawm kev siv tag nrho cov ntub dej, dispersion, adhesion thiab lwm yam dej num ntawm surfactants, ruaj khov emulsions tuaj yeem npaj tau.
Thaum rov ntub dej, nws yuav tsis emulsify dua, ua kom yooj yim los npaj cov emulsions tsis muaj zaj duab xis tsim cov neeg ua haujlwm.
Muaj peev xwm yaj cov roj theem siab rau hauv dej los ua (o / w) emulsion
Muaj peev xwm npaj tau: moisturizing cream, tshuaj pleev ib ce, tshuaj ntxuav lub ntsej muag, tshuaj pleev thaiv hnub, tshuaj tsw qab tsis muaj cawv, tshuaj pleev plaub hau (txhim kho cov luster, yooj yim rau zuag), ntxuav tes
Tus neeg sawv cev, tsis muaj qhov sib xws ntawm cov tshuaj tsuag emulsion thiab pob tshab microemulsion, thiab lwm yam. Muaj ntau txoj hauv kev los txo qhov nyuaj ntawm carbomer hauv daim ntawv thov. Ib txoj hauv kev yog ntxiv carbomer rau cov roj theem system kom qeeb nws qhov o, uas yog hu ua indirect method, tab sis qhov no nyob ntawm cov qauv. Capom tsis tshua nkag siab rau cov kev hloov pauv hauv cov txheej txheem ntxiv.
