Dab tsi yog cov kev ua tau zoo ntawm PVP \/ P OVI TONG K qauv K15, K30, K90, thiab lwm yam?

Cov txheej txheem

1. Taw qhia: Ntau-Dagensional Daim Ntawv Thov Tus Nqi Ntawm Pvp

2. Kev tsom xam ntawm cov tub ntxhais kev ua haujlwm sib txawv ntawm K series

3. Kev sib piv ntawm daim ntawv thov teb thiab cov kis

4. Kev lag luam hauv ntiaj teb thiab thev naus laus zis thev naus laus zis

5. Cov ntaub ntawv cov ntaub ntawv: cov ntsiab lus tseem ceeb thiab muaj feem cuam tshuam nrog PVP K Series

6. Yav Tom Ntej Prospaps: R & D Kev Taw Qhia ntawm Cov Khoom Muaj Nqi Muaj Nqi

1. Taw qhia: Ntau-Dagensional Daim Ntawv Thov Tus Nqi Ntawm Pvp

Raws li cov tsis-ionic high molecular polymer,polyvinylprolidone (pvp)Tau dhau los ua cov khoom siv ua haujlwm tseem ceeb hauv cov qauv tshuaj, tshuaj pleev ib ce, kev lag luam, thiab lwm yam. Vim nws solubility zoo, biocompatiety thiab tshuaj ruaj khov. Ntawm lawv, K series (xws li K15, K9, K90) tau muab faib los ntawm molecular phaus los ua cov kev pab them tag nrho los ntawm cov viscosity discersion rau high-viscosity thickening. Kab lus no sib xyaw ua ke sib xyaw ua ke thiab kev nce qib thev naus laus zis ua rau pom qhov sib txawv thiab kev ua lag luam daim ntawv thov kev lag luam cov qauv kev lag luam sib txawv K.

2. Kev tsom xam ntawm cov tub ntxhais kev ua haujlwm sib txawv ntawm K series

● Cov lus txhais ntawm molecular hnyav thiab K tus nqi

K tus nqi yog suav tus nqi raws li PVP afative viscosity ntawm lub cev muaj zog, uas yog qhov tseeb ntawm cov roj afelated nrog molecular hnyav (}}} rel) \/ c). Piv txwv li:

K15: Qhov hnyav molecular ntawm txog 10, 000}, k tus nqi ntawm {3}}

K30: kev hnyav hnyav ntawm txog 40, 000}, k tus nqi ntawm 27-32

K90: Lub cev hnyav li ntawm 1,300, 000}, k tus nqi ntawm {4}}

● Solubility thiab viscosity cov yam ntxwv

Qes K Nqi (k 15- k30):

Kev tshem tawm sai sai hauv dej thiab loj polrvents, nrog tsawg kawg viscosity (xws li K30 aqueous daws viscosity ntawm 2. · S). 5 mpa-·

High K tus nqi (k 60- k90):

Qhov kev cais tawm qeeb qeeb tab sis cov viscosity puas muaj ntau dua 55 mpais · s kom ncav cuag cov ntsiab lus thiab lub sij hawm ntev kev ua yeeb yam.

● Sib txawv sib txawv ntawm zaj duab xis-ua cov khoom thiab adhesion

K3 {{0: Thaum siv los ua phau ntawv qhia hauv cov tshuaj, nws muaj kev sib tw ntawm cov tshuaj tua hluav taws xob nrog tsawg dua lossis sib npaug rau 30 feeb.

K90: hauv cov duab kom hniav zoo nkauj npaj, nws cov yeeb yaj kiab siab-ua kom muaj zog (tensile lub zog ntau dua los yog sib npaug ntawm 45 MPA) muab cov nyhuv ntev ntev thaum tswj kev ua pa.

3. Kev sib piv ntawm daim ntawv thov teb thiab cov kis

Kev lag luam kev lag luam: kev hloov pauv ntawm K30 rau K90

Cov ntaub ntawv: Daim ntawv thov ntawm PVP K30 hauv ibuprofen granules tuaj yeem nce cov tshuaj muaj zog los ntawm 20% thaum txo cov hluav taws xob ntau lawm los ntawm 15 degree).

● Tshuaj pleev ib ce: Synergistic nyhuv ntawm K series hauv cov mis

K30: Raws li cov ua npuas ncauj, ntxiv 1% -2}}% rau tshuaj zawv plaub hau tuaj yeem nce cov npuas dej los ntawm 30%.

K90: Hauv cov tshuaj pleev thaiv hnub, nws yog qhov sib xyaw nrog cov titanium dioxide kom nce UV thaiv kev ua hauj lwm rau 98% (piv nrog 92% ntawm tio₂).

Cov qauv siv tshiab: K30 \/ K90 cov qauv sib xyaw (piv 1: 3) yog siv rau kev sib npaug ntawm kev teeb tsa cov plaub hau ntawm kev teeb tsa lub zog thiab kev sib koom ua lag luam tau nce los ntawm 12% txhua xyoo.

● Muaj cov teb: xaiv tau yog ntawm cov dispersants thiab stabilizers

K15: Qhov kev rho tawm effermiciency hauv ceramic ink yog 1.8 lub sij hawm uas ntawm cov tsoos tsoos, thiab cov particle loj faib d90 tsawg dua lossis sib npaug rau 200 nm.

K60: raws li tus neeg sawv cev ntawm tus txiv neej rau kev rov qab los rau cov roj av rov qab, nws tuaj yeem nce cov roj av roj rov qab rau 65% (ib txwm muaj tsawg dua lossis sib npaug nrog 50%).

4. Kev lag luam hauv ntiaj teb thiab thev naus laus zis thev naus laus zis

● Raws li cov kev tshawb fawb thoob ntiaj teb, kev ua lag luam thoob ntiaj teb yuav ncav cuag $ 1.23 lab xyoo 2024, ntawm uas:

Kws Tshuaj PvP Account rau 45% (8.2% Cagr)

Thov kom High-xaus K90 qauv surges, tshwj xeeb tshaj yog nyob rau hauv biopharmaceutical teb (kev lag luam loj hlob ntawm 22% hauv 2023).

● Technology sib faib:

Hla-txuas polyvinylprolidry (PVPP) ua tiav 3- Kev tawg ua rau ntawm qhov ncauj tawm ntawm qhov ncauj-tso cov kev ua lag luam sai sai.

Daim ntawv thov PvP \/ VA Copolymers (xws li plasdone® s63 {}} 2}}}) hauv 3D luam tawm tsawg dua lossis sib npaug rau 0.1 hli.

5. Cov ntaub ntawv cov ntaub ntawv: cov ntsiab lus tseem ceeb thiab muaj feem cuam tshuam nrog PVP K Series

6. Yav Tom Ntej Prospaps: R & D Kev Taw Qhia ntawm Cov Khoom Muaj Nqi Muaj Nqi

Lub hom phiaj tshuaj: k {90-} hloov nanoparticles (me me<100 nm) can achieve a tumor tissue enrichment rate of 70%.

Tus phooj ywg ib puag ncig PvP: Kev tshawb fawb thiab kev txhim kho NVP monomers (carbon hneev taw txo los 40%), kev ua lag luam

Cov Khoom Siv Txawj Ntse: Kev thov sib luag ntawm pvp copolymers hauv kev npaj ua pa tawm.

Tus kws tshaj lij ntawm PVP K series lees paub cov khoom tsim kev tsim txiaj ntawm qhov hnyav molecular yog ua haujlwm ". Nrog kev nce qib ntawm cov tshuaj ntsuab thiab cov khoom siv ntsuab ntawm K90 thiab siab dua cov khoom lag luam hnyav yuav txuas ntxiv kho cov toj roob hauv pes. Kev lag luam yuav tsum tsom rau kev sib tw sib txawv thiab tsim cov kev sib tw sib txawv hauv kev ua raws li cov kev tshuaj tiv thaiv (xws li USP \/ EP cov kev pabcuam.
