Povidone K90 Binder

Lub binder yog dab tsi?

Binders tuav cov khoom xyaw hauv ib ntsiav tshuaj ua ke. Binders xyuas kom meej tias cov ntsiav tshuaj thiab granules tuaj yeem tsim nrog lub zog xav tau, thiab muab ntim rau cov ntsiav tshuaj uas tsis muaj zog.

Cov ntaub ntawv tseem ceeb:

Polyvinylpyrrolidone

Khoom npe: Povidone excipient

CTFA lub npe: POLYVINYL PYRROLIDONE

CAS Nr.: 9003-39-8

Cov mis mos molecular: (C6H9NO)n

Xim: Dawb los yog lub teeb daj

Odor: Tsis muaj ntxhiab tsw lossis me ntsis tsw

Ntim: 25kg / cardboard nruas

Keeb kwm: Suav teb

Solubility:

Polyvinylpyrrolidone k90 yog dej-soluble polymer, uas tsis yog tsuas yog miscible nrog dej, tab sis kuj soluble nyob rau hauv ntau yam cawv, carboxylic acids, amines, thiab lwm yam organic solvents.

Film-forming zog:

Polyvinylpyrrolidone k90 muaj cov yeeb yaj kiab zoo heev. PVP tuaj yeem cam khwb cia lossis coated los ua ib zaj duab xis thaum yaj hauv qee cov kuab tshuaj xws li dej, methanol, ethanol, thiab lwm yam).

Daim ntawv thov:

(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.
