CTFA lub npe: POLYVINYLPYROLIDONE

CSC No.: 9003-39-8

Cov mis mos molecular: (C₆H₆TSIS) n

Keeb kwm: Suav teb

Lub cev muaj zog:

Solubility:

PVP yog cov dej-soluble polymer, uas yog miscible nrog dej thiab tuaj yeem yaj hauv ntau cov kuab tshuaj organic 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 siv hauv tshuaj pleev ib ce.

Dispersibility thiab solubilization: me me molecule PVP muaj cov nyhuv dispersing zoo, tiv thaiv cov khoom los ntawm agglomerating thiab nag lossis daus. PVP tuaj yeem ua rau kom muaj dej ntau ntawm ntau cov tshuaj hauv cov tshuaj aqueous.

complexity:

O atoms hauv PVP molecule. N atom yog ib qho kev sib koom ua ke ntawm atom, uas ua rau nws yooj yim nrog qee yam tshuaj, xws li iodine, benzene, amorpholine thiab ntau yam sulfonamides.

Daim ntawv thov:

Adhesive:PVP muaj cov viscosity zoo thiab yog siv los ua cov nplaum nplaum nplaum nplaum, cov nyiaj muas, cov pab pawg, cov ntaub qhwv plaster, thiab lwm yam.

Txheej thiab inks: PVP muaj cov khoom tawg zoo heev. Cov coatings ntxiv nrog PVP nce viscosity, txhim kho xim lub zog, tshem tawm qhov tshwm sim ntab, tawg thiab ruaj khov cov xim xim, txhim kho gloss, thiab zam cov xim flocculation thiab nag lossis daus.
