HPMC
HPMC Hydroxypropyl Methyl Cellulose
Cov khoom muag
HPMC yog ib tug semi-synthetic nonionic cellulose tov ether uas feem ntau tshwm raws li ib tug dawb los yog dawb-zoo li hmoov. Nws yog npaj los ntawm kev hloov kho tshuaj ntawm natural cellulose.
Cov dej zoo solubility: Nws tuaj yeem yaj sai sai hauv cov dej txias los tsim cov kua nplaum pob tshab.
cov yam ntxwv ntawm cov khoom
Cov thickening zoo heev: Txhim kho cov viscosity thiab sib xws ntawm cov kua, txhim kho fluidity thiab stability.
Kev tsim cov yeeb yaj kiab zoo heev: Thaum qhuav, ib zaj duab xis tawv yog tsim, uas yog dej resistant, breathable thiab saj zawg zog.
Zoo biocompatibility: Non-toxic, tasteless, non-irritating, haum rau biomedicine teb.
Environmentally degradable: Ib txwm degradable nyob rau hauv ib puag ncig, nyob rau hauv txoj kab nrog cov kev cai ntawm ntsuab ib puag ncig tiv thaiv.
khoom siv
Kev tsim kho kev lag luam: Siv los ua tus neeg saib xyuas dej thiab tus neeg saib xyuas ntawm cov cement mortar los txhim kho kev sib kis thiab lub sijhawm ua haujlwm; Raws li cov nplaum nplaum, nws yog siv los muab cov ntaub ntawv zoo nkauj xws li cov vuas thiab marbles.
Txheej kev lag luam: Raws li cov thickener, dispersant thiab stabilizer, txhim kho kev ua haujlwm ntawm cov txheej txheem.
Pharmaceutical teb: Nws tuaj yeem siv los ua cov khoom siv zaj duab xis, kev tso tawm tus neeg sawv cev, cov khoom siv lub plhaub capsule, kev pab cuam tshuam, thiab lwm yam.
Khoom noj khoom haus kev lag luam: Ua raws li thickener, emulsifier, stabilizer thiab lwm yam dej num.
Cov txheej txheem ntau lawm
Feem ntau paj rwb, ntoo ua raw cov ntaub ntawv, los ntawm alkalization, propylene oxide thiab chloromethane etherification txheej txheem los npaj.
Kev lag luam zeem muag
Nrog rau kev txhim kho kev lag luam thoob ntiaj teb thiab kev paub txog ib puag ncig, nws txoj kev xav tau kev lag luam txuas ntxiv mus ntxiv. Cov ntawv thov hauv cov vaj tsev ntsuab, cov txheej txheem tiv thaiv ib puag ncig, biomedicine thiab lwm yam kev lag luam txuas ntxiv nthuav dav, thiab kev lag luam yuav tsum nthuav dav ntxiv. Tab sis tib lub sijhawm, kev lag luam tseem tab tom ntsib cov teeb meem hauv kev tsim kho thev naus laus zis, kev sib tw ua lag luam thiab kev tiv thaiv ib puag ncig.
siv ceev faj
Nyob rau hauv tus txheej txheem ntawm kev siv, nws yog ib qhov tsim nyog yuav tau xyuam xim rau cov txheej txheem dissolution, thiab xaiv qhov tsim nyog dissolution txoj kev raws li cov qauv sib txawv. Nyob rau tib lub sijhawm, xyuam xim rau kev cia khoom, yuav tsum tau muab tso rau hauv qhov chaw qhuav, huv si txias kom ntseeg tau tias cov khoom zoo thiab kev ua haujlwm zoo.
