Polyvinylpyrrolidone K 25

PVP K25 kev ua haujlwm:

Solubility: PVP yog cov dej-soluble polymer, uas tsis yog tsuas yog miscible nrog dej, tab sis kuj soluble nyob rau hauv ntau cov organic solvents xws li cawv, carboxylic acids, amines, thiab halogenated hydrocarbons.

Zaj duab xis-forming zog: PVP muaj cov yeeb yaj kiab zoo heev. PVP tuaj yeem cam khwb cia lossis coated los ua ib zaj duab xis thaum yaj hauv qee cov kuab tshuaj xws li dej, methanol, ethanol, thiab lwm yam.

Kev nqus dej: PVP muaj zog nqus dej thiab moisturizing zog, thiab feem ntau yog siv rau hauv cov tshuaj pleev ib ce siab heev.

Dispersibility thiab solubility: PVP ntawm me me molecules muaj cov nyhuv dispersing zoo, tiv thaiv cov khoom los ntawm agglomerating thiab precipitating. PVP tuaj yeem ua rau kom muaj dej ntau ntawm ntau cov tshuaj hauv cov tshuaj aqueous.

Complexing: O atom thiab N atom nyob rau hauv lub PVP molecule yog ib qho kev sib koom tes atoms, uas ua rau nws mus complex nrog tej yam tshuaj, xws li iodine, benzene, amorpholine thiab ntau yam sulfonamides.

Daim ntawv thov kev lag luam:

Adhesive: PVP cov tshuaj muaj viscosity zoo thiab yog siv los ua cov nplaum nplaum nplaum nplaum, cov nyiaj muas, band-aids, plaster bandages, thiab lwm yam.

Txheej thiab inks: PVP muaj cov khoom tawg zoo heev. Cov coatings ntxiv nrog PVP tuaj yeem ua kom viscosity, txhim kho tinting zog, tshem tawm cov tshwm sim ntab, tawg thiab ruaj khov cov xim xim, txhim kho gloss, thiab tsis txhob pigment flocculation thiab nag lossis daus.

Membrane thiab cov ntaub ntawv tshiab: PVP tuaj yeem tsis tsuas yog txhim kho lub hydrophilicity ntawm daim nyias nyias, tab sis kuj tuaj yeem tswj tau cov membrane pore loj thiab kev faib tawm los ntawm kev xaiv PVP nrog qhov sib txawv molecular hnyav thiab tswj qhov sib ntxiv. Tsis tas li ntawd, PVP muaj cov ntawv thov hauv thaj chaw ntawm cov ntaub ntawv tshiab xws li cov ntaub ntawv txo qis, kho qhov muag fibers, laser discs, photo-curable resins, thiab cov ntaub ntawv photosensitive.

Kev lag luam hluav taws xob: PVP yog siv rau hauv cov duab-kua nplaum ntawm cov duab thaij duab los ua kom qhov sib txawv thiab kev daws teeb meem ntawm cov duab raj. Nws kuj tseem siv tau rau hauv cov roj teeb nickel-chromium thiab lithium, thiab cov ntawv luam tawm hauv Circuit Court.
