Kutsunga kuri nyore kwemhando ye hydroxyprupyl methylcellose

Kufunga kunaka kweiyo hydroxypropyl methylcellose (HPMC) kazhinji inosanganisira kuongorora kiyi dzinoverengeka paramita zvine chekuita nezvivakwa zvemuviri uye zvemakemikari. Heino nzira yakapusa yekuona mhando yeHPMC:

1. Chitarisiko: Wongorora kutaridzika kweHPMC poda. Inofanirwa kunge iri yakanaka, yemahara-inoyerera, chena kana yakachena-chena poda isina chero kusvibiswa kusvibiswa, clamps, kana discums. Chero zvipi zvipi zvipi zvacho kubva pachitarisiko ichi chinogona kuratidza kusvibiswa kana kusvibiswa.
2. Kuchena: Tarisa kuchena kweiyo hpmc. Yakakwira-mhando HPMC inofanirwa kunge iine huwandu hwakanyanya hwekuchena, kazhinji hunoratidzwa nedanho rakaderera rekusvibiswa senge unyoro, ADH, uye isimbe. Ruzivo urwu runowanzopihwa pane yechigadzirwa chechigadzirwa chechidimbu kana chitupa chekuongororwa kubva kumugadziri.
3. Viscosity: Sarudza iyo viscosity yeHPMC Solution. Nyungudusa huwandu hweHPMC mumvura maererano nemirairo yemugadziri kugadzirira mhinduro yeiyo yakataurwa yakatsanangurwa. Kuyera iyo visikopa yemhinduro uchishandisa viscometer kana rheometer. Iyo viscosity inofanirwa kunge iri mukati meiyo yakataurwa yakapihwa neiyo mugadziri wegiredhi rinodiwa reHPMC.
4. Particle saizi kugoverwa: Ongorora iyo size saizi yekugovera yeHPMC poda. Saizi yehukuru inogona kukanganisa zvivakwa senge solubility, kupararira, uye kuyerera. Ongorora iyo Sizele Scution Kupararira uchishandisa maitiro akadai seLaser difrraction kana microscopy. Iyo yekugovera saizi yekugovera inofanirwa kusangana nezvinotaurwa zvakapihwa nemugadziri.
5. Zvinyorwa zvekunyorovedzera: Sarudza iyo unyoro hwemukati yeHPMC poda. Kunyanyisa unyoro kunogona kutungamira mukukanda, kushatisa, uye kukura kwemicrobial. Shandisa iyo inonyungudza analyzer kana karl Fischer titration kuyera iyo yakanyorova zvemukati. Zvemukati zvinyoro zvinofanirwa kunge zviri mukati meiyo yakatarwa yakapihwa nemugadziri.
6. Chemical Composition: Wongorora mamiriro emakemikari eiyo hpmc, kusanganisira iyo degree rekutsiva (DS) uye zvirimo zvehydroxyprupropropyl uye methyl mapoka. Nyanzvi dzekuongorora dzakadai sekutenderera kana kuti spectroscopy inogona kushandiswa kuona iyo DS uye makemikari okuumbwa. Iyo DS inofanirwa kuwirirana neiyo yakataurwa huwandu hwegiredhi rinodiwa reHPMC.
7. Solubility: Ongorora iyo solubility yeHPMC mumvura. Nyungudika huwandu hushoma hweHPMC mumvura maererano nemirairo yemugadziri uye tarisa maitiro ekunyungudika. Yakakwira-mhando HPMC inofanira kunyungudika nyore uye gadzira mhinduro yakajeka, viscous isina chero inooneka macumps kana zvakasara.

Nekuongorora iyi parameter, iwe unogona kuona mhando yehydroxypropyl methylcellose (HPMC) uye ita simbisa kukodzera kwekunyorwa kwechinangwa. Izvo zvakakosha kutevera mirayiridzo yemugadziri uye yakatarwa panguva yekuedza kuti uwane mibairo chaiyo.
