He aha ka Polyvinylpyrrolidone Cross-linked PVPP Cas 25249-54-1?

ʻO ka polyvinylpyrrolidone cross-linked (PVPP) he polymer i hoʻopaʻa ʻia i hiki ʻole ke hoʻoheheʻe ʻia i ka wai, nā ʻakika ikaika, nā kumu ikaika, a me nā mea hoʻoheheʻe kūlohelohe maʻamau, i hana ʻia e ka polymerization o nā monomers vinyl pyrrolidone ma lalo o nā kūlana kikoʻī.Ma ke ʻano he huahana kemika maikaʻi polymer koʻikoʻi, loaʻa i ka PVPP nā waiwai maikaʻi a kūʻokoʻa, a ua hoʻohana nui ʻia i nā mea hoʻonaninani, nā meaʻai, nā lāʻau lapaʻau a me nā māla ʻē aʻe.
