Chii chinonzi Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1?

Polyvinylpyrrolidone cross-linked (PVPP) ipolymer ine cross-linked isinganyungudike mumvura, maasidhi akasimba, mabhesi akasimba, uye zvinonyungudutsa zvakasikwa, zvinoumbwa nepolymerization yevinyl pyrrolidone monomers pasi pemamiriro chaiwo. Sechigadzirwa chakakosha chepolymer fine chemical, PVPP ine hunhu hwakawanda hwakanaka uye hwakasiyana, uye yakashandiswa zvakanyanya muzvizoro, chikafu, mishonga nedzimwe nzvimbo.

Kushandiswa

PVPP, sechigadzirwa chakakosha chemakemikari akanaka epolymer, ine hunhu hwakawanda hwakanaka uye hwakasiyana, uye polyvinylpyrrolidone yakabatana yakashandiswa zvakanyanya muzvizoro, chikafu, mushonga nedzimwe nzvimbo. Nekuda kwehuremu hwakawanda hwemamorekuru uye chimiro chekubatanidza chepolyvinylketone yakabatana, polyvinylpolypyrrolidone pvpp hainyungudike mumvura asi inogona kukonzera kuti chimiro chayo chenetwork chiwedzere uye chiparare kana chasangana nemvura. PVPP inoshandiswa zvakanyanya semushonga wekuparadza mapiritsi mukurapa, pamwe nesimbi inomisa, mushonga wekusanganisa zvikamu zvemishonga, uye mushonga wekusanganisa matannins nemapolyphenols mumishonga inobva mumiti.
