Daim ntawv thov:
Cov khoom plig PVP muaj cov nplaum nplaum, zaj duab xis-sib sau ua, dispersing thiab thickening zog, uas yog dav siv hauv kev lag luam kws. Lawv yog ib qho ntawm peb lub khoom siv khoom siv loj tshaj plaws thiab pom zoo thoob ntiaj teb.


Kev Sau Npe Tag Nrho:

* Tsawg molecular phaus PVP, siv raws li tus neeg sawv cev daws teeb meem, crystallization inhibitor thiab tshem tawm kev tswj hauv injectables thiab ophthalmic formulations. Xws li PVP K12, K15, K17. * Medium Molecular PVP, siv rau cov binder hauv ntsiav tshuaj, capsules thiab granular, raws li tus stabilizer rau lub qhov ncauj tawm, tus neeg saib xyuas lub cev, tus sawv cev cev, tus kabmob rau cov pigments, raws li tus enzyme stabilizer thiab txhim kho bioavailability. eg PVP K25, K30. * High molecular, ib pob nyhuv zoo, rau peb li stabilizer hauv lub qhov ncauj thiab pleev xim rau, ua ib lub thickener, tus neeg saib xyuas yam ntxwv xws li PVP K60, K90.

1. Cov Khaub Ncaws Ntawm Cov Kws Tseg: PVP K25, K30, K90 tag nrho cov muaj siab khi ua tau zoo, lawv yog cov tsim rau cov ntub qe thiab kev sib txuas ncaj ntawm cov ntsiav tshuaj. KoVidone TM K25 siv ntau tshaj li ntawm K30 thiab K90, vim nws cov low viscosity. Conversely, KoVidone TM K90 siv tsawg dua vim nws qhov siab ruaj khov khoom.

2. Cov tshuaj Solubilizers, Solvents thiab Crystallization inhibitors: Tsis tshua muaj cev nyhav rau PVP K12, K15, K17 yog siv rau kev siv cov tshuaj ua kom siv tau, cov tshuaj dispersants thiab crystallization inhibitors, tshem tawm cov stabilizers rau cov tshuaj thiab cov khoom muag cov khoom muag.

3. Dispersant los yog tus neeg sawv cev ntawm cov paib: PVP K25 los yog K30 ua raws li kev sib tsoo lossis cov khoom siv degradable hauv cov tshuaj uas tsis ua kom tiav, thiab yuav ua rau cov tshuaj yaj yeeb tsawg heev. Cov kev siv no yog sib tov lub PVP thiab yeeb tshuaj, thiab tom qab ntawd muab tshuaj tsuag no mus rau tus cab kuj, lub cev los yog cov ntsiav tshuaj.

4. Kev tshem tawm ruaj ruaj: PVP K25, K30 thiab K90 yog qhov tsim nyog rau kev ruaj ntseg ntawm kev ncua nrog ntau yam khoom xyaw; cov qhabnias yuav raug kho yog PVP K90 siv nrog Poly PVP.

5. Zaj duab xis / qab zib Coatings, cov duab zaj duab xis: PVP K25, K30 ua yeeb yaj kiab-forming cov neeg ua haujlwm, adhesion promoters thiab pigment dispersers, thiab feem ntau yog siv los ua cov txheej txheem qab zib thiab film txheej.

6. Cov neeg ua haujlwm tawm: KoVidone TM K90 yog tsim rau siv raws li tus neeg saib xyuas cov thickening rau cov kua dej haus cawv rau kev siv qhov ncauj thiab tshuaj pleev xim.

7. Pore-qub: PVP K30 tuaj yeem siv raws li plhaws-tus laus hauv lub cev thiab daim npav thaiv cov kabmob K90 thiab cov K90 tuaj yeem ua tus neeg sawv cev hauv cov khoom kho mob.

8. Kev txhim kho bioavailability, tswj kev tso tawm kev pab tawm: PVP K12, K15, K17, K30, K90 tuaj yeem siv los kho qhov ceev ntawm qee cov kev daws teeb meem.

9. Cov Khoom Noj Khoom Haus: PVP K25, K30, K60, K90 siv tau rau hauv cov pluas noj zaub mov, xws li Vitamin, cov khoom noj muaj fiber ntau, cov khoom qab zib.

10. Lwm cov ntawv thov: cov tshuaj ntsaws ntsev hauv dej, tshuaj ntxuav cov qhov muag lo ntsiab muag, kev kho kom lub cev muaj zog thiab cov tshuaj cwj pwm, kev tiv thaiv kev tiv thaiv.


Cov lus hais:

PVP yog muaj rau daim ntawv thov kom zoo nkauj / Kev tu tus kheej, lawv raug thov kom muaj kev tshwj xeeb thiab kev coj dawb huv ntawm cov khoom kom zoo nkauj / tus kheej tu cev.
