Khoom piav qhia:

PVP k30 yog ib qho tsis yog-ionic polymer compound, uas yog ib qho kev kawm ntau ntxiv ntawm cov khoom siv tshuaj zoo ntawm N-vinylamide polymers. Ntawm lawv, tus nqi K yog qhov ua tau zoo ntawm cov txheeb ze viscosity ntawm PVP aqueous tov. tus nqi. Tau tsim ua peb pawg ntawm non-ionic, cationic thiab anionic, peb qhov tshwj xeeb ntawm qib kev lag luam, qib tshuaj, thiab qib zaub mov, thiab ntau homopolymers, copolymers thiab cross-linked polymers nrog cov txheeb ze molecular hnyav li ntawm ntau txhiab mus rau ntau tshaj ib. lab.

Daim ntawv thov:

Povidone k30 yog siv dav hauv kev lag luam tshuaj, thiab nws yog ib qho ntawm cov khoom siv hluavtaws, tuaj yeem siv los ua cov tshuaj dispersant rau cov kua tshuaj thiab cov tshuaj pleev xim.

Lub cev muaj zog:

1.Complexity:

PVP k30 yog ib qho polymer uas muaj peev xwm "solving" siab. Qhov kev muaj peev xwm "solving" no yog vim nws cov yam ntxwv ntawm cov polar siab thiab cov pab pawg amide uas tuaj yeem txais cov saw hlau hydrogen hauv nws cov qauv molecular, nrog rau cov pab pawg tsis yog polar. Ob leeg ntawm cov pab pawg no muaj peev xwm "kua" cov pab pawg sib raug ntawm cov khoom me me molecule.

2. Nto ua haujlwm:

Lub molecule ntawm PVPK30 muaj ib tug butyrolactam qauv, uas muaj ib tug loj polar lactam pawg nrog ib tug dipole lub sij hawm ntawm 40, uas muaj peev xwm ua hydrophilic thiab polar pawg. Tsis tas li ntawd, muaj cov tsis-polar methylene (-CH₂-) thiab methine (CH=) pawg ntawm lub nplhaib molecular thiab hauv cov saw ntev, ua rau lipophilic.
