Nyob rau lub sijhawm thaum npaj tshuaj yog tas li tshiab cov ntaub ntawv tau dhau los ua qhov tseem ceeb cov txuas nrog kev txhim kho tshuaj muaj txiaj ntsig thiab kev ua kom ua tau tshuaj zoo. Hla-txuas polyvinylprolidone, raws li kev zam nrog kev ua tau zoo thiab tshuaj tawm tshiab, nws tau coj cov tshuaj tshiab thiab tawg mus rau tom teb ntawm cov chaw tsim khoom.
2. Cov yam ntxwv ntawm Cross-Txuas Polyvinylprolidone
Crampovidone, lub npe hu ua Cross-txuas-txuas polyvinyl pyrrolidone, muaj tus qauv sib tw sib txuas nrog peb-ntu. Tus qauv tshwj xeeb no muab nws ua kom muaj kev cais tawm zoo heev, thiab ua cov ntsiav tshuaj thiab lwm cov ntaub ntawv tshuaj thiab lwm cov tshuaj. Nyob rau tib lub sijhawm, nws tseem muaj cov kua zoo thiab zaws zaws thiab ua haujlwm tau yooj yim thiab ua haujlwm thaum npaj ntau lawm thiab cov khoom lag luam zoo.

3. Daim ntawv thov hauv cov tshuaj npaj
● Txhim kho kev siv tshuaj solubility thiab cov lej sib cais
Ntau cov yeeb tshuaj muaj cov solubility tsis muaj kev txwv lawv txoj kev nqus thiab cov xyoob ua haujlwm hauv lub cev. Hla-TxuasPolyvinylprolidoon CrosslinkingMuaj peev xwm txhim kho cov solubility ntawm kev tsim cov khoom tawg nrog cov tshuaj. Thaum lub sij hawm npaj npaj, cov tshuaj thiab hla-txuas polyvinylprolidone tau sib xyaw ntawm cov theem molecular los ua ib lub xeev zoo uniform rau amorphous xeev. Qhov amorphous txo cov crystallinity ntawm cov tshuaj frystallinity ntawm cov tshuaj hauv dej hauv dej, yog li nce kev sib cais ntawm cov tshuaj.
Txhim kho cov ntsiav tshuaj disintegration ua rau ua tau zoo
Rau cov ntsiav tshuaj, tus nqi sib liam ncaj qha cuam tshuam rau kev sib cais thiab kev nqus cov tshuaj. Raws li tus neeg tsis ua haujlwm superinthat, tso pa tawm cov qauv sib txawv. Thaum cov ntsiav tshuaj tuaj nkag mus rau hauv dej, ua yeeb yaj kiab tuaj yeem nqus dej sai sai, thiab txhawb nqa cov khoom siv ceev ceev ntawm cov ntsiav tshuaj. Piv nrog tsoos dismants, cornovidone tseem tuaj yeem tswj cov kev ua tau zoo nyob rau hauv siab av noo, kom cov tshuaj no tuaj yeem tso tawm sai.
● Pab txhim kho cov tshuaj ruaj khov
Qhov ruaj khov ntawm cov tshuaj yog qhov tseem ceeb rau lawv qhov zoo thiab ua tau zoo. Hla-txuas polyvinylprolidone tuaj yeem sib cuam tshuam nrog cov tshuaj los ntawm hydrogen tsev los ua cov khoom sib cais ruaj khov. Qhov kev sib cuam tshuam no tsis tsuas yog pab tswj lub xeev amorphous nkaus xwb, tab sis kuj tseem tiv thaiv cov tshuaj khaws cia, yog li txhim kho kev ruaj khov ntawm cov tshuaj. Hauv kev sim nrawm nrawm, cov khoom tawg nrog boss-txuas polyvinylprolidone raws li cov cab kuj tseem tuaj yeem tswj hwm lub zog zoo thiab kev thauj mus los ntawm cov tshuaj.
Ntau cov kev siv dav dav
Hla-txuas polyvinylprolidone yog qhov tsim nyog rau kev tsim qauv kev txhim kho ntawm ntau yam tshuaj, tshwj xeeb tshaj yog rau cov tshuaj soluble. Nws tuaj yeem tsim cov kev faib tawm nrog cov tshuaj los ntawm cov txheej txheem npaj xws li tshuaj tsuag kom qhuav, nrog cov txheej txheem yooj yim thiab yooj yim kev lag luam. Txawm hais tias nws tau ua rau hauv cov hmoov lossis ntsiav tshuaj, hla kev sib txuas polyvinylprolidone tuaj yeem ua si nws cov cim tshwj xeeb kom tau raws li qhov kev xav tau ntawm kev ua kom sib txawv.
Hauv ntej, raws li cov kev siv tshuaj ntsuab siab, hla kev sib txuas ua yeeb yam zoo hauv kev txhim kho yeeb tshuaj solubility, txhim kho cov cwj pwm sib txawv thiab cov ntsiav tshuaj ua kom muaj zog ua kom tsis sib xws. Nws muab cov tuam txhab kws tshuaj nrog kev daws teeb meem thiab ruaj khov, uas pab tsim cov khoom lag luam zoo thiab muaj txiaj ntsig ntau. Xaiv cov ntoo khaub lig-txuas polyvinylprolidine txhais tau tias xaiv kev hloov tshiab thiab tawg hauv kev npaj tshuaj.
4. Kev Lag Luam Kev Tsim Kho Kev Lag Luam
Tsis ntev los no, ntau lub tuam txhab kws tsim hluav taws xob tau nce lawv cov peev txheej R & D tau nce polyvinylprolidone-hais txog kev npaj thev naus laus zis-thiab tag nrho kev lag luam tau qhia tias muaj kev sib tw tawg. Raws li cov neeg ua si tseem ceeb hauv kev lag luam, hangzhou zaj sawv ntshuam ntshuam & Export Co., Ltd.tau koom nrog nws thiab pab txhawb kev pab ntau yam thev naus laus zis tshiab. Hais txog cov kev tshawb fawb thev naus laus zis thiab kev txhim kho hauv ntiaj teb tau ua rau muaj kev sib txuas lus hauv ntiaj tebHla Txuas PolyvinylprolidoneCov thev naus laus zis no tuaj yeem ua tiav cov tshuaj muaj tseeb thiab ntev ntev, thiab tam sim no tau nkag mus hauv cov chaw kuaj mob theem. Nrog nws cov peev txheej dav dav thiab kev tshawb fawb ua lag luam los ntawm kev tshawb fawb & Export Co., Ltd. Muab cov khoom siv roj raw thiab nthuav tawm
Nyob rau tib lub sijhawm, nyob rau hauv cov nqe lus ntawm kev txo cov nqi ntau lawm ntawm bexininylprolidone, lwm lub tuam txhab kws tshuaj tau ua tiav cov txiaj ntsig zoo kawg li. Lawv tau ua tiav tsim ib txheej txheej txheem ntawm cov txheej txheem tshiab uas tau txo cov nqi sib txuas, nphing lub hauv paus tseem ceeb rau nws cov ntaub ntawv npaj dav. Hangzhou Zaj sawv Ntshuam ntshuam & export koom tes nrog cov tuam txhab kev ua haujlwm loj tuaj yeem pab tau los ntawm cov tuam txhab kev ua haujlwm zoo nkauj thiab txhawb nqa cov tuam txhab sib tw, yog li cov khoom lag luam Risned
Ib qho ntxiv, ntau lub tsev tshawb fawb tshawb fawb tseem nquag tshawb xyuas cov chaw thov tshiab rau cov neeg hla kev tshawb fawb tshiab, thiab tau ua tiav thawj zaug kev tshawb xyuas NANA cov neeg nqa khoom tshiab. Hangzhou Zaj sawv Ntshuam ntshuam & Export Co., Ltd. muab kev pabcuam kev tshawb fawb txog kev tshawb fawb txog kev tshawb fawb txog kev tshawb fawb, pab crossedCrosslinked polyvinylprolidoneKev tshawb fawb tau nyob rau hauv cov chaw ua yeeb tshuaj xws li cov kws nqa tshuaj uas tshiab nano, thiab pab txhawb kev txhim kho kev kho mob hauv ntiaj teb no.
Raws li kev ua tshuaj siv thev naus laus zis txhim kho kom muaj peev xwm ntau dua, raws li cov tsheb ciav hlau npaj, ua cov cab kuj zoo rau kev npaj, yuav ua rau cov cab kuj zoo rau kev npaj, yuav ua rau cov ntaub ntawv thov kev dav dav. Nyob rau yav tom ntej, nws yuav tsum tau hais txog kev hloov kho tshiab ntxiv thiab kev txhim kho cov tshuaj tiv thaiv kev ua haujlwm, nws yuav ua rau cov khoom siv tshuaj zoo thiab ua tau zoo dua rau cov neeg mob.
