Daim ntawv thov
Carbomer yog ib qho tseem ceeb thickener. Nws yog lub siab polymer crosslinked los ntawm acrylic acid los yog acrylate thiab allyl ether. Nws cov khoom muaj xws li polyacrylic acid (homopolymer) thiab acrylic acid / C10-30 alkyl acrylate (copolymer). Raws li cov dej-soluble rheological modifier, nws muaj cov thickening thiab ncua kev kawm ntawv, thiab yog dav siv nyob rau hauv coatings, textiles, kws, kev tsim kho, detergents thiab tshuaj pleev ib ce.
Uni-Carbomer 2020 yog ib qho kev hloov kho hydrophobic, cross-linked acrylate copolymer uas muaj qhov nruab nrab mus rau siab viscosity, du, ntev fluidity, thiab muaj zog thickening zog tshaj pH dav. Lub dispersion viscosity yog tsawg, yooj yim rau siv twj tso kua mis; Nws kuj tseem siv tau rau hauv cov tshuab uas muaj cov surfactants nruab nrab, muab cov electrolyte tsis kam thiab ib qho tshwj xeeb rau kev tsim, ua rau nws haum rau ntau daim ntawv thov.
Kev ua tau zoo thiab cov txiaj ntsig
1. Yooj yim rau disperse thiab yooj yim rau siv
2. Nws muaj cov nyhuv ntawm kev ua haujlwm siab thickening, ncua kev kawm ntawv thiab stability
3. Nws muaj qee yam ntsev tsis kam
4. Zoo heev electrolyte kuj
5. Cov pob tshab zoo heev
Daim ntawv thov teb:
Tshuaj zawv plaub hau
Emulsion
Cov plaub hau tu thiab tawv nqaij gel
Da dej gel.
Tswv yim:
1. Kev pom zoo siv yog 0.2-1.5wt
2. Thaum dispersing cov polymer, koj tuaj yeem pom qhov tsim ntawm txheej txheej thiab flocculated hais ua ntej stirring.Yuav kom tau homogeneous dispersions, nws raug nquahu kom nce cov concentration ntawm dispersions ≥ 2.0wt %.
3. Thaum siv nyob rau hauv cov ntsiab lus siab saum npoo active system, nws raug nquahu kom ntxiv surfactant ua ntej kom tsis txhob muaj cov surfactant cuam tshuam qhov txuas ntxiv ntawm cov saw molecular ntawm Kapo resin, yog li cuam tshuam rau viscosity, transmittance thiab yield tus nqi ntawm nruab nrab thiab qhov kawg.
Kev ua haujlwm hauv qab no raug txwv, txwv tsis pub ua rau poob lub peev xwm thickening:
- Ntev do los yog siab-shear do tom qab neutralization
- Ntev UV irradiation
- Ua ke nrog electrolytes
