Hydroxypropyl methylcellulose muaj thickening, khi, dispersing, emulsifying, zaj duab xis-forming, suspending, adsorbing, gelling, nto active, noo noo-retaining thiab tiv thaiv colloid zog.Qhov ntau ntawm kev siv yog dav heev.
Kev zoo
Qhov zoo ntawm hydroxypropyl methylcellulose feem ntau muaj 80 mesh thiab 100 mesh.Qhov zoo tshaj qhov fineness, qhov ceev ntawm dissolution, feem ntau hais lus, qhov zoo dua.Feem ntau, ntsug reactors tsim cov khoom nyias dua li kab rov tav reactors.
Kev xa tawm
Dissolve hydroxypropyl methylcellulose (HPMC) hauv dej los tsim cov kua pob tshab.Saib nws lub teeb transmittance.Qhov loj dua lub teeb transmittance, qhov zoo dua, qhia tias muaj tsawg insolubles nyob rau hauv nws.
kev faib ua feem
Qhov loj me me yog qhov zoo dua.Yog tias qhov tshwj xeeb lub ntiajteb txawj nqus loj dhau los yog tsawg dhau, nws yuav yog qhov tshwm sim ntawm kev tswj tsis zoo thaum lub sijhawm tsim khoom.
Sab nrauv
Ntshiab HydroxyPropyl methylulose yog visually fluffy thiab muaj qhov tsawg bultity, xws li 0.3-0.4g / ml;Adult HPMC muaj fluidity zoo dua thiab xav tias hnyav dua, uas yog pom tseeb txawv ntawm cov khoom tiag hauv qhov tsos.Cov tsos ntawm qee lub hom phiaj tshwj xeeb cellulose kuj txawv ntawm cov kev qhia tshwj xeeb, thiab cov khoom tshwj xeeb raug tshuaj xyuas kom meej.
aqueous daws
Ntshiab HPMC aqueous tov yog ntshiab, siab transmittance, dej tuav tus nqi ≥ 90%;HPMC aqueous tov yog turbid, thiab cov dej tuav tus nqi yog qhov nyuaj mus txog 70%
BaiDu
Txawm hais tias kev ua kom dawb tsis tuaj yeem txiav txim siab seb HPMC puas siv tau yooj yim, thiab yog tias cov tshuaj ntxuav hniav dawb ntxiv thaum lub sijhawm tsim khoom, nws yuav cuam tshuam rau nws qhov zoo.Txawm li cas los xij, feem ntau ntawm cov khoom zoo muaj cov xim zoo nkauj.
