Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1
ʻO ka Polyvinylpyrrolidone cross-linked (PVPP) kahi polymer cross-linked i hoʻoheheʻe ʻole ʻia i ka wai, nā waikawa ikaika, nā kumu ikaika, a me nā mea hoʻoheheʻe organik maʻamau, i hoʻokumu ʻia e ka polymerization o nā monomers vinyl pyrrolidone ma lalo o nā kūlana kikoʻī. Ma ke ʻano he huahana kemika polymer maikaʻi koʻikoʻi, he nui nā waiwai maikaʻi a kū hoʻokahi o PVPP, a ua hoʻohana nui ʻia i nā mea hoʻonani, meaʻai, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe.

ʻO PVPP, ma ke ʻano he huahana kemika polymer maikaʻi koʻikoʻi, he nui nā waiwai maikaʻi a kū hoʻokahi, a ua hoʻohana nui ʻia ka polyvinylpyrrolidone i hoʻopili ʻia i nā mea hoʻonani, meaʻai, lāʻau lapaʻau a me nā ʻoihana ʻē aʻe. Ma muli o ke kaumaha molekala kiʻekiʻe a me ke ʻano hoʻopili ʻana o ka polyvinylketone i hoʻopili ʻia, ʻaʻole hiki ke hoʻoheheʻe ʻia ka polyvinylpolypyrrolidone pvpp i ka wai akā hiki ke hoʻonui koke i kona ʻano pūnaewele a hele i ka disintegration i ka wā e hālāwai ai me ka wai. Hoʻohana nui ʻia ka PVPP ma ke ʻano he mea disintegration no nā papa i ka lāʻau lapaʻau, a me he mea hoʻopaʻa hoʻomaha, he mea hoʻohuihui no nā ʻāpana lāʻau lapaʻau, a he mea hoʻohuihui no nā tannins a me nā polyphenols i nā lāʻau lapaʻau mea kanu.
