Khoom piav qhia:

Pvp k30 polymer polymer yog ib hom non-ionic polymer compound. Nws yog ib qho kev kawm ntau dua cov khoom siv tshuaj zoo ntawm N-vinylamide polymers. Ntawm lawv, tus nqi K yog qhov ua tau zoo ntawm cov txheeb ze viscosity ntawm PVP aqueous tov. tus nqi. Nws tau tsim ua peb pawg ntawm non-ionic, cationic thiab anionic, peb qhov tshwj xeeb ntawm qib kev lag luam, qib tshuaj, thiab qib zaub mov, thiab ntau homopolymers, copolymers thiab crosslinked polymers nrog cov txheeb ze molecular hnyav li ntawm ntau txhiab mus rau ntau tshaj ib lab. .

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.

Cov kws tshaj lij 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.

(1) Kev npaj cov tshuaj vitamin ruaj khov

Cov roj-soluble vitamins (A, D, E) muaj peev xwm npaj tau raws li cov kev daws teeb meem hauv cov roj hydrogenated los yog waxes, thiab tom qab ntawd dispersed raws li cov hlaws zoo heev hauv cov yas yas uas muaj cov kab noj hniav. Cov khoom zoo li no muaj kev ruaj khov txawm tias tom qab lub sijhawm ntev raug rau huab cua kub.

(2) Siv los ua stabilizer hauv kev npaj kua hauv qhov ncauj

PVP K-90 muaj ntau yam kev siv hauv cov ntawv ua kua hauv qhov ncauj. tuaj yeem siv kom tau txais cov khoom lag luam homogeneous thiab ruaj khov.

(3) Daim ntawv thov hauv ophthalmology thiab lwm yam tshuaj

①1 feem pua ​​~ 2 feem pua ​​concentration ntawm K90 tuaj yeem siv los txo qhov muag qhov muag; ②Nws tuaj yeem txhim kho cov nyhuv ntawm kev sib cuag lub lens ntxuav cov tshuaj; ③ Piv nrog HPMC, methylcellulose lossis polyvinyl cawv thaum siv benzalkonium chloride nyob rau hauv daim ntawv tshuaj, muaj ob peb compatibility teeb meem; ④ cov adhesion puas tsuaj ntawm cov tev-hauv cov lo ntsiab muag yog qhov tsawg heev; ⑤ piv nrog rau lwm cov polymers, nws muaj lub siab tshaj plaws biocompatibility rau 0.1 feem pua ​​tropicamide; Rau cov kua muag dag, nws zoo dua li polyvinyl cawv; ⑦ Nws tuaj yeem siv los ua tus pore-forming tus neeg sawv cev rau cov txheej txheem tso tawm hauv lub qhov muag ntev ntev.

Hais txog peb:

Ulanqab Kema New Material Co., Ltd muaj thaj chaw zoo, ze rau Tuam Tshoj Capital Economic Zone, 11 lub nroog-theem lub nroog suav nrog Beijing, Tianjin, Hebei Xeev, thiab ob lub nroog ncaj qha los ntawm kev tswj hwm lub xeev. Nws kuj tseem nyob ze rau qhov chaw tsim khoom tseem ceeb ntawm cov khoom siv raw, thiab cov nqi thauj mus los kuj tseem qis. Calcium carbide yog cov khoom tseem ceeb ntawm niam txiv lub tuam txhab Baiyan Lake Chemical, thiab nws npaj yuav tsim BDO thiab -butyrolactone, yog li cov khoom siv thiab kev thauj mus los ntawm cov khoom siv raw rau yav tom ntej muaj kev lees paub thiab qhov zoo.

Lub tuam txhab muaj chaw ua haujlwm zoo, thiab cov neeg ua haujlwm ntawm lub tuam txhab koom ua ke, aiming muab kev pabcuam zoo tshaj plaws rau cov neeg siv khoom.
