Product Description:

Polyvinylpyrrolidone (PVP) yog non-ionic polymer. Tam sim no, PVP muaj kev lag luam nyob rau hauv ntau qib viscosity xws li qhov hnyav molecular mus rau qhov hnyav molecular. Cov kev faib tawm no, ua ke nrog nws cov solubility hauv aqueous/organic solvent systems, non-toxicity, and stability to acid, ntsev, thiab tshav kub, muab PVP zoo daim ntawv thov yooj. Cov ntawv thov kev lag luam ntawm PVP suav nrog, piv txwv li, siv los ua cov ntaub ntawv los txhim kho lub zog thiab tuab; nce lub zog ntawm daim ntawv ntau lawm; siv raws li ib tug resin txheej; txhim kho dye coloring nyob rau hauv hluavtaws fibers; thiab nws kuj yog feem ntau siv hauv inks, imaging, lithography, thiab detergents. Thiab xab npum, textiles, pottery, hluav taws xob fais fab, metallurgy, thiab raws li ib tug polymer additive. Vim nws zoo heev adhesion, film-forming, dispersion thiab thickening zog, PVP kuj yog siv dav hauv kev lag luam tshuaj.

PVP tau muab qhab nia raws li nws qhov hnyav nruab nrab molecular, thiab feem ntau cim los ntawm tus nqi K. Cov txiaj ntsig K sib txawv sawv cev qhov sib txawv nruab nrab molecular qhov hnyav ntawm PVP. Tus nqi K yog qhov tseeb tus yam ntxwv muaj feem xyuam nrog cov txheeb ze viscosity ntawm PVP aqueous tov, thiab viscosity yog lub cev muaj nqis ntsig txog qhov hnyav molecular ntawm cov polymer. Yog li ntawd, tus nqi K tuaj yeem siv los qhia qhov nruab nrab molecular hnyav ntawm PVP. Feem ntau hais lus, qhov ntau dua tus nqi K, qhov viscosity ntau dua.

Cov khoom no yog Polyvinylpyrrolidone 25 (Polyvinylpyrrolidone K25), hu ua PVP-25, nrog qhov nruab nrab molecular hnyav ntawm 24,000.
