Hydroxyethyl cellulose yog ib nrab rau viscosity siab ether, tshwj xeeb tshaj yog thaum siv viscosity dej siab thiab cov ntawv thov viscosity yog tsawg. Cellulose ether yog ib qho yooj yim mus tawg hauv dej txias nrog pX cov kua dej ≤ ≥ 7.5, yog li peb yuav tsum them sai sai rau qhov tsis txaus ntseeg ntawm cellulose ether.
Nta thiab siv ntawm hydroxyethyl cellulose:
1. Anti-enzyme tsis-ionic dej thickener, uas tuaj yeem siv tau rau hauv ntau tus nqi ntawm PHIC (PH = 2-12).
2. Yooj yim rau disperse, nws tuaj yeem ntxiv ncaj qha rau hauv daim ntawv ntawm cov hmoov qhuav lossis hauv daim ntawv ntawm slurry thaum sib tsoo cov xim thiab fillers.
3. Kev tsim kho zoo heev. Nws muaj qhov zoo ntawm kev ua haujlwm txuag, tsis yooj yim txau thiab dai, thiab txaws zoo heev.
4. Zoo sib xyaw nrog ntau cov surfactants thiab tshuaj txuag tau siv hauv cov xim looj.
5. Qhov ntim viscosity yog ruaj khov, uas tuaj yeem tiv thaiv cov xim looj ntawm cov xim kom tsawg dua vim yog cov enzymes nyob rau hauv dav dav hydroxyethyl cellulose.
Cov khoom ntawm hydroxyethyl cellulose
Hydroxyethyl cellulose ether yog cov dej tsis-ionic-soluble polymer. Nws yog cov hmoov dawb lossis lub teeb daj uas ntws tau yooj yim. Feem ntau insoluble nyob rau hauv feem ntau cov kuab tshuaj organic
1. HEC yog Soluble hauv dej kub lossis dej txias, thiab tsis nag lossis dej sov, uas ua rau nws muaj ntau yam ntawm solubility, thiab tsis-thermal gelation.
2. Nws yog tsis-ionic thiab tuaj yeem uake nrog lwm cov dej-soluble polymers, solfactants, thiab ntsev. Nws yog ib qho zoo tshaj plaws colloidal thickener rau cov kev daws teeb meem muaj cov siab electrolytes.
3
4. Piv nrog lees paub methyl cellulose thiab hydroxypropyl cellulose, lub dispersing muaj peev xwm ntawm HEC yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv kev muaj zog (yeeb yaj kiab).
Sam xim
Cuam tshuam rau kev ua haujlwm, xws li: tsho tshaj, txaws tsis kam, ploj tsis kam; Tus qauv tshwj xeeb ntawm cov qauv ntawm cellulose tuaj yeem pab cov hmoov hauv txheej txheej, maj mam ua kom tau cov txiaj ntsig zoo.
Cov Dej Zoo Kuj
Tom qab cov xim zaj duab xis yog kom qhuav kiag li, nws muaj dej tsis kam tiv. Qhov no tshwj xeeb tshaj yog qhia txog tus nqi ntawm nws cov dej tsis kam nyob rau hauv lub siab-PVC qauv txheej txheem. Los ntawm txawv teb chaws tsim qauv, nyob rau hauv no High-compent-pvc system, tus nqi ntawm cellulose ete ete yog qhov tseem ceeb 4,6 ‰.
Cov dej zoo heev
Hydroxyethyl cellulose tuaj yeem rub tau lub sijhawm sib raug thiab tswj lub sijhawm kom qhuav kom tau txais kev ua yeeb yaj kiab zoo dua; Ntawm lawv, cov dej tuav tseg ntawm methyl cellulose poob siab tshaj li ntawm 50%, qhov tshwm sim rau lub caij ntuj sov thiab kub tau nce.
Kev ruaj khov zoo los txo flocculation ntawm cov xim
Tshem tawm cov sedimentation, synergesis thiab flocculation; Lub caij no, hydroxyethyl cellulose ether yog cov khoom tsis yog ionic. Tsis muaj kev tawm tsam nrog ntau yam kev sib ntxiv hauv cov kab ke.
Kev sib raug zoo zoo nrog ntau xim system
Zoo heev ntau qhov sib xws ntawm cov xim, cov xim thiab fillers; Hydroxyethyl cellulose muaj qhov kev txhim kho xim zoo tshaj plaws, tab sis tom qab kev hloov kho, xws li methyl thiab yuav muaj cov phom sij ntawm cov xim xim.
Kev sib raug zoo zoo nrog ntau cov ntaub ntawv raw
Nws tuaj yeem siv rau ntau txheej txheej tsim.
Siab antimicrobial kev ua si
