Kusiyana pakuthupi ndi mankhwala pakati pa HPMC ndi hemc

Hydroxypropyl methylcelulose (hpmc) ndi hydroxyelyl nothcellulose (hemc) ndi celloulose etrase omwe amagwiritsidwa ntchito kwambiri m'mafakitale ndi katundu wawo. Ngakhale nyumba zawo zamankhwala zilinso chimodzimodzi, pali kusiyana kwakukulu mu zinthu zomwe zimawapangitsa kukhala oyenera pakugwiritsa ntchito mitundu.

Kapangidwe ka 1.Chemical:

Onse a HPMC ndi hemc amachokera ku cellulose, polymer yachilengedwe. Kusiyanitsa kwakukulu kumakhala m'magulu ophatikizidwa ndi msana wa m'Chuma. Ku HPMC, miniti yolowera methyl ndi hydroxypropyl, pomwe hemo, m'malo mwake zimaphatikizapo methyl ndi hydroxyethyl. Izi zimatha kukhudza katundu wa cellulose.

2. Solubility:

Kusiyana kwakukulu pakati pa HPMC ndi hemoc ndi njira yawo yosungunuka. HPMC imawonetsa bwino kusungunuka bwino m'madzi ozizira poyerekeza ndi hemc. Katunduyu ndiwofunikira kwambiri pazogwiritsa ntchito zomwe zimafunikira kufalikira kwamphamvu kapena kufalikira kwa ma polima, monga m'mafakitale opangira mankhwala komanso omanga.

3. Kusunga kwamadzi:

HPMC nthawi zambiri imakhala ndi madzi osasungidwa kuposa hemc. Katunduyu ndi wofunikira kwambiri pantchito monga njira zozikitsira za simementi, pomwe kusungitsa kwamadzi kumathandizira kuwongolera njira ya hydration ndikuwongolera kutopa.

4. Kutentha kwa gel gel:

Kutentha kwambiri ndikutentha komwe yankho kapena kubala limasandulika kukhala gel. Hemc nthawi zambiri imakhala ndi ma gels pamtunda wotsika kuposa HPMC. Katunduyu amatha kukhala wopindulitsa pantchito monga zakudya, komwe kutentha kochepa kumafunikira kuti zikhale mwatsatanetsatane.

5.Rological katundu:

Onse a HPMC ndi hemc amathandizira kuti zikhale zachiwerewere kapena zovuta. Komabe, zovuta zawo pa mafakisoni komanso ku Shear mikangano ingasiyane. Hemc nthawi zambiri imapereka ma viscossies apamwamba kwambiri otsika, ndikupanga kukhala koyenera kugwiritsa ntchito zina zomwe zimafunikira mayankho ambiri.

6. Mapangidwe a filimu:

HPMC ndi hemc imatha kupanga mafilimu oonda mukamagwiritsidwa ntchito pamwamba. Kutengera ndi ma cellulose ether, mafilimuwo akuwonetsa mitundu yosiyanasiyana. Makanema a HPMC nthawi zambiri amatha kusinthasintha, pomwe hemc amasinthana. Katunduyu amakhudza kugwiritsa ntchito pomatira, zomata ndi mapulogalamu ena opanga mafilimu.

7. Kugwirizana ndi mitundu ina:

Kusankha pakati pa HPMC ndi hemc kumatengera kuphatikizira kwawo ndi zina. Mwachitsanzo, hpmc nthawi zambiri amakondedwa mu mankhwala osokoneza bongo chifukwa cha kuyenderana kwake ndi zosakaniza zosiyanasiyana, pomwe hemc imatha kusankhidwa kuti azigwiritsa ntchito pazomwe zimagwirizana.

8. Kukhazikika kwa mafuta:

Ma cellose onse a cellouse amawonetsa kukongola kwa mafuta, koma kutentha komwe kumasiyana. HPMC imakonda kukhala ndi kukhazikika kwamphamvu poyerekeza ndi hemac. Izi ndizofunikira pakufunsira komwe kuwonekera kwa kutentha kwambiri ndikuganizira.

Ngakhale HPMC ndi hemc imagawana msana wofala kwambiri celluulose, mpweya wawo wapadera wamankhwala amabwera chifukwa cha mitundu yosiyanasiyana ya mankhwala ndi mankhwala. Kumvetsetsa izi ndikofunikira posankha ethel ethel ether ya omwe adapatsidwa, ndikuwonetsetsa zoyenera komanso magwiridwe antchito. Kusankha pakati pa HPMC ndi hemc kumatengera zofunikira mwatsatanetsatane za pulogalamuyi, kuyambira pa mankhwala opangira mankhwala ndi zida zomanga chakudya ndi zokutira.
