Specification:

1, Dej haus kev lag luam:
PVP-P tuaj yeem siv rau hauv
- Txhim kho qhov zoo thiab txuas ntxiv lub txee lub neej ntawm npias los ntawm kev nqus cov polyphenyls thiab tannoids.
- Tiv thaiv 'pinking' thiab 'browning' cov tshuaj tiv thaiv hauv cov cawv dawb thiab sparkling cawv
- Txhim kho aroma thiab tsw hauv cawv liab
PVP-P yog tus nqi-zoo thiab kev nyab xeeb hauv kev lag luam npias uas
- Ua tiav insoluble hauv npias
- Muaj feem xyuam rau txhua hom npias
- Kev ua tau zoo dua - qis dua
- Yooj yim rau siv thiab zoo heev tuav cov yam ntxwv
- Cov txheej txheem Insoluble pab, nrog kev pom zoo dav dav
- Tsis muaj kev cuam tshuam tsis zoo rau ua npuas ncauj, tsw qab lossis lwm yam tsis zoo
- Txhim kho dispersion thiab sedimentation yam ntxwv
- Ntev lim khiav ntev dua piv rau silica ib leeg
- Siv cov cuab yeej cog ntoo uas twb muaj lawm

2, Kev Lag Luam Pharmaceutical: Muab kev tawg sai sai hauv ntau hom kev sib xyaw ntawm qhov ncauj thiab cov txheej txheem. Tshwj xeeb tshaj yog nyob rau hauv cov cheeb tsam hauv qab no:
- Hauv cov ntsiav tshuaj ntub dej granulation txheej txheem.
- Qhov zoo tshaj plaws rau kev siv nrog cov tshuaj compressible tsis zoo thiab hauv cov txheej txheem ntawm cov ntsiav tshuaj ncaj qha.
- Kev ua tau zoo tshaj plaws hauv kev tsim cov tshuaj ionic, acidic thiab alkaline active tshuaj
- Ceev ceev thiab chewable ntsiav tshuaj
- Kho cov kab mob hauv plab thiab ua cov tshuaj tiv thaiv kab mob raws plab.
Tsis tas li ntawd, PVP-P kuj tuaj yeem siv los txhim kho kev solubility, thiab yog li ntawd, txhim kho bioavailability tsis yog tib neeg nkaus xwb, tab sis kuj siv cov kws kho tsiaj.

Khoom noj khoom haus qib PVPP

Khoom Properties:PVPP yog hygroscopic, insoluble nyob rau hauv dej thiab tag nrho lwm cov kuab tshuaj, tab sis nws swells sai nyob rau hauv aqueous solutbition tsis muaj gel los ntawm.

Daim ntawv thov:Ua tsaug rau nws cov khoom insoluble hauv dej thiab lwm yam kuab tshuaj, PVPP yog dav ua raws li stabilizers & clarifier rau Npias / Wine thiab lwm yam dej haus cov khoom, nws muaj peev xwm romove polyphenols thiab tannins tshuaj thaum lub sij hawm lub npias / Wine / dej haus ua.
