ʻO Copovidone
ʻO Copovidoneme ka 60/40 ration o N-Vinylpyrrolidone iā Vinyl Acetate, hiki ke hoʻoheheʻe ʻia i ka hapa nui o nā mea hoʻoheheʻe i loko o ke kino. ʻO ka hoʻoheheʻe maikaʻi i ka wai, ka waiʻona a me nā mea hoʻoheheʻe kūlohelohe ʻē aʻe.
Nā Papahana Huahana Nui:
| Helehelena | White a melemele-keʻokeʻo paha he lepo a i ʻole flakes, hygroscopic |
| Viscosity (Express as K Value) | 25.20 ~ 30.24 |
| Solubility | Hiki ke hoʻoheheʻe ʻia i ka wai, i ka wai ʻona a me ka methylene chloride |
| Nāʻike | A. Hoʻomaʻemaʻe infrared |
| ʻIke ʻia ke kala ʻulaʻula ʻo BA | |
| ʻIke ʻia ka waihoʻoluʻu viole CA | |

| ʻO Hydrazine | 1 ppm max. |
| Nā Monomers (VP + VA) | 0,1% max. |
| Ka maʻemaʻe A (2-Pyrrolidone) | 0.5% max. |
| ʻO nā mea hao kaumaha (e like me Pb) | 20 ppm max. |
| Lilo ma ka hoʻomaloʻo ʻana | 5.0% max. |
| ʻAlepa Sulphated | 0,1% max. |
| ʻO ka ʻikepili ʻo Ethenyl Acetate | 35.3 ~ 42.0% max. |

Nā noi:
Hoʻohana nui ʻia ʻo Copovidone ma ke ʻano he mea hoʻopaʻa hiki ke hoʻoheheʻe ʻia i ka wai a me ka mea hoʻopaʻa maloʻo i nā kaʻina hana pulu / pololei, a hiki ke hoʻohana ʻia ma ke ʻano he mea kiʻi ʻoniʻoni.
* ʻO ka mea hoʻopaʻa papa wai hiki ke hoʻoheheʻe ʻia, kūpono i ka granular a maloʻo paha / nā kaʻina hana hoʻopili pololei.
* Kiʻi Kiʻi ʻoniʻoni: permeable film coating no ka papa ʻaila a me ke kō e pale ai i ka hoʻokaʻawale ʻana, hoʻoliʻiliʻi i ka noʻonoʻo a hāʻawi i ka adhesion kiʻi ʻoniʻoni maikaʻi.
