PVP K30(9003-39-8)
Mafotokozedwe Akatundu
● PVP-K30 ndi nonionic polima pawiri, amene ndi wabwino mankhwala mitundu ndi kafukufuku mozama ndi zambiri mu N-vinyl amide ma polima, kumene K mtengo kwenikweni khalidwe mtengo wogwirizana ndi makulidwe wachibale wa PVP amadzimadzi yankho.
● PVP K30 yapangidwa kukhala mndandanda wa ma homopolymers, copolymers ndi ma polima ophatikizika m'magulu atatu: nonionic, cationic ndi anionic, ndi mafotokozedwe atatu: kalasi ya mafakitale, kalasi ya mankhwala ndi kalasi ya chakudya, ndi ma molekyulu achibale kuyambira zikwi zingapo mpaka zikwi zingapo. oposa miliyoni imodzi.
