PVP K30 Polymer9003-39-8

Pvp k30 polymer polymer yog ib hom non-ionic polymer compound. Nws yog ib qho kev kawm ntau dua 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. Nws tau tsim los 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 crosslinked polymers nrog cov txheeb ze molecular hnyav li ntawm ntau txhiab mus rau ntau tshaj ib lab. .

Solubility thiab kev daws cov yam ntxwv

Zoo li txhua yam khoom lag luam homopolymer series, vim tias Pvp k30 polymer muaj pawg hydrophilic thiab lipophilic hauv nws cov qauv molecular, nws tuaj yeem cuam tshuam nrog ntau cov kuab tshuaj, ua rau nws soluble hauv dej, thiab soluble hauv ntau hom cawv thiab carboxylic acids. , Amines thiab halogenated hydrocarbons thiab lwm yam organic solvents. Lub solubility tsuas yog txwv los ntawm nws tus kheej viscosity.

Pvp k30 polymer, uas muaj peev xwm yaj nyob rau hauv ntau yam ntawm cov organic solvents, ua rau nws lug siv nyob rau hauv zus tau tej cov dej kho daim nyias nyias thiab yog ib tug zoo heev membrane porogen. Siv lub hollow fiber membrane ua los ntawm PVDF ua piv txwv, PVPK30, PVDF thiab lwm yam fillers yog co-solved nyob rau hauv organic solvents xws li DMF los yog DMAc los ua ib tug casting tov. Tom qab spinning thiab lwm yam txheej txheem tom ntej, nws yog gelled nyob rau hauv cov dej theem los yog cov cawv theem los tsim membrane filaments nrog uniform pore diameters.
