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

Polyvinylpyrrolidone cross-linked (PVPP) is cross-linked polymer iyo isinganyunguriki mumvura, yakasimba acids, mabhesi akasimba, uye general organic solvents, inoumbwa ne polymerization yevinyl pyrrolidone monomers pasi pemamiriro ezvinhu chaiwo. Sechinhu chakakosha chepolymer yakanaka chigadzirwa chemakemikari, PVPP ine akawanda akanakisa uye akasiyana zvivakwa, uye yakashandiswa zvakanyanya muzvizoro, chikafu, mushonga uye mamwe minda.

Application

PVPP, seyakakosha polymer yakanaka makemikari chigadzirwa, ine akawanda akanakisa uye akasiyana zvivakwa, uye yakashandiswa zvakanyanya muzvizoro, chikafu, mushonga uye mamwe minda. Nekuda kwehuremu hwemamorekuru uye muchinjika-unobatanidza chimiro chemuchinjiko-yakabatana polyvinylketone, hainyurike mumvura asi inogona kukurumidza kuita kuti network yayo iwedzere uye nekuparara kana yasangana nemvura. PVPP inoshandiswa zvakanyanya sechinhu chinoparadzana chemapiritsi mumishonga, pamwe chete nekusimudzirwa kwekusimudzira, mumiririri wekugadzira mishonga yemishonga, uye mugadziri wekugadzira tannins uye polyphenols mumiti-based drugs.
