Polyvinylpyrrolidone K 30 Siv Ua Adhesive

Khoom Paub meej

Adhesive yog dab tsi?

Adhesive, tseem hu ua kua nplaum, cement, mucilage, los yog muab tshuaj txhuam, yog cov khoom tsis yog xim hlau siv rau ib lossis ob qho tib si ntawm ob qho khoom sib cais uas khi lawv ua ke thiab tiv thaiv lawv cov kev sib cais.

Dab tsi yog qhov zoo ntawm polyvinylpyrrolidone nplaum?

1.Rau cov neeg ua hauj lwm uas nkag siab rau cov av noo thiab cua sov, siv PVP ethanol tov raws li ib tug binder tuaj yeem tshem tawm cov yam ntxwv xws li dej thiab cua sov. Rau cov tshuaj hydrophobic, cov tshuaj aqueous tuaj yeem sib xyaw ua ke, thiab cov khoom siv tshuaj tuaj yeem muaj kev sib raug zoo. Cov dej muaj txiaj ntsig los ua kom muaj kev sib cais ntawm cov tshuaj.

2.PVP tuaj yeem muab ntxiv los ua cov hmoov qhuav ua cov ntawv khi, thiab nws tuaj yeem siv rau ntub granulation nrog cov kuab tshuaj haum los yog ua cov ntawv qhuav qhuav rau compression ncaj qha los txhim kho qhov tshwm sim ntawm cov tshuaj hydrophobic. Feem ntau siv K30 thiab K25, qhov ntau npaum ntawm PVPK30 feem ntau yog 2 feem pua ​​-5 feem pua.

Daim ntawv thov:

PVP yog soluble hauv dej thiab qee qhov feem ntau siv cov kuab tshuaj organic, ua rau nws siv tau ntau zaus. Ua ntej tshaj plaws, rau cov neeg ua haujlwm uas nkag siab zoo rau cov av noo thiab cua sov, siv PVP ethanol tov raws li cov ntawv khi tuaj yeem tshem tawm cov yam ntxwv xws li dej thiab cua sov. Rau cov tshuaj hydrophobic, cov tshuaj aqueous tuaj yeem sib xyaw ua ke, thiab cov khoom siv tshuaj tuaj yeem muaj kev sib raug zoo. Cov dej muaj txiaj ntsig los ua kom muaj kev sib cais ntawm cov tshuaj. Tsis tas li ntawd, PVP tuaj yeem muab ntxiv ua cov hmoov qhuav ua cov ntawv khi, thiab nws tuaj yeem siv rau cov ntaub ntub dej nrog cov kuab tshuaj uas tsim nyog lossis ua cov ntawv qhuav qhuav rau kev sib txuas ncaj qha los txhim kho qhov tshwm sim ntawm cov tshuaj hydrophobic. Feem ntau siv K30 thiab K25, qhov ntau npaum ntawm PVPK30 feem ntau yog 2 feem pua ​​-5 feem pua.

Hauv kev siv tus neeg sawv cev effervescent, PVP yog cov nplaum zoo tagnrho, vim tias tus neeg sawv cev effervescent yuav tsum muaj kev tswj xyuas nruj ntawm cov dej noo, siv PVP ethanol tov raws li cov nplaum yuav daws tau qhov teeb meem no zoo. Cov ntsiav tshuaj effervescent yog li ua tau zoo hauv kev qias neeg, yaj sai, thiab tuaj yeem ua npuas dej. Siv li ntawm 5 feem pua ​​-10 feem pua ​​PVP cov tshuaj raws li ib tug binder kuj yuav siv tau rau fluidized txaj tsuag ziab granulation.

Tus kws kho mob tshwj xeeb sib xyaw diclofenac sodium nrog cov hmoov txhuv nplej siab, lactose, thiab lwm yam, nplawm thiab granulated nrog DQD ethanol tov kom tau txais cov granules tam sim ntawd. Nqa ib feem ntawm cov granules tam sim ntawd thiab coated nrog ethyl cellulose, ethanol, thiab acetone tov kom tau txais kev tso tawm granules. Cov saum toj no ob granules yog tov ntawm 7 K 5 thiab ces encapsulated. Nws tseem tau tshaj tawm tias lub plab zom mov uas tau tso tawm-tso tshuaj ntsiav qhia cov tshuaj tso tawm tau zoo.

Nov yog daim duab ntawm K30 30 feem pua ​​​​aqueous tov
