Hydroxypyl methyl celluse vs methyl cellulose

Cellulose ndiye gawo lalikulu la makhoma a cell ndi polymer yochuluka kwambiri padziko lapansi. Ma cellulose amagwiritsidwa ntchito pogwiritsa ntchito mafakitale osiyanasiyana, kuphatikizapo chakudya, mankhwala opangira mankhwala ndi zomangamanga. Mankhwala awiri otchuka kwambiri a celloulose ndi hydroxypypyl methylcellulose (hpmc) ndi methylclulose (MC). Zinthu ziwirizi nthawi zambiri zimagwiritsidwa ntchito mosiyanasiyana, koma ali ndi kusiyana kwakukulu komwe kuyenera kuganiziridwa.

Kodi hydroxypropyl a methylcelulose ndi chiyani?

Hydroxypylpyl notiosellulose ndi ma celluuse osungunuka, osungunuka amadzi kuchokera ku cellulose yachilengedwe. Kupanga kwa masentimita kwa HPMC kumafanana ndi cellulose kwachilengedwe, ndikupangitsa kuti ikhale yothandiza pa ntchito zambiri zamasudzo. Zosavuta zake zapadera, kuphatikizapo kusungunuka ndi mawonekedwe, pangani zoyenera kugwiritsa ntchito zomangira, chakudya, mankhwala opangira mankhwala ndi zodzoladzola.

Mawonekedwe a HPMC:

1. Solubility:
Chimodzi mwa zabwino zothandiza kwambiri za HPMC ndi kusungunuka kwake. HPMC imasungunuka mosavuta m'madzi ozizira, ndikupanga chomveka bwino, chokhazikika kwambiri, mawonekedwe a viscous. Izi zimapangitsa kuti hpmc zikhale zomatira bwino kwa mafakitale angapo, kuphatikizapo zomangamanga ndi mankhwala.

2. Makutu:
HPMC ili ndi mafayilo apamwamba ndipo ndiyabwino zakumwa. Mawonekedwe ake okwera amapezeka makamaka kwa hydroxypyl yake ndi methoxy magwiridwe antchito, zomwe zimawonjezera mphamvu yake yopanga ma hydrogen ndikulimbikitsa mamolekyulu amadzi.

3. Mapangidwe a filimu:
HPMC ndi othandizira opanga mafilimu ndipo amagwiritsidwa ntchito m'makampani opanga mankhwala ophimbira mapiritsi ndi makapisozi. Izi zimapangitsa chotchinga chinyezi ndi zinthu zina zachilengedwe, zomwe zingafupitse moyo wa alumali.

4.
HPMC ndi yoyera kwambiri ndipo ndichilengedwe chomwe chili ndi mankhwala ovulaza. Izi zimapangitsa kukhala koyenera kwa chakudya ndi malo odzikongoletsa.

Kodi Methyllulose ndi chiyani?

Methylcellulose ndiwonso wa cellulose wochokera ku ulusi wa cellulose. Ndi eyiti ya meter ya cellulose, ndipo mawonekedwe ake a maselo ake ndi osiyana kwambiri ndi cellulose yachilengedwe, yomwe imapangitsa kuti ikhale yovuta kuwonongeka ndi enzyme kuwonongeka. Methylcellulose ndi gawo losokoneza m'mafakitale osiyanasiyana kuphatikiza chakudya, mankhwala opangira mankhwala, zomangamanga ndi zodzola.

Makhalidwe a MethylClulose:

1. Madzi Kusungunuka:
Methylcellulose imasungunuka mosavuta m'madzi ozizira, ndikupanga zomveka, zowoneka bwino, komanso yankho lalikulu. Koma kusungunuka kwake ndikotsika kuposa hpmc. Izi zimapangitsa kuti zikhale zoyenera kugwiritsa ntchito m'mafakitale omwe amafunikira kusungunuka kwakukulu, monga makampani omanga.

2. Makutu:
Methylcellulose ili ndi mawonekedwe owoneka bwino ndipo ndi abwino zakumwa zakumwa. Mavinyewa ake amadziwikanso ndi magulu ake a methyl omwe amalumikizana ndi mamolekyulu amadzi.

3. Mapangidwe a filimu:
Methylcellulose ndi othandizira opanga mafilimu abwino ndipo imagwiritsidwa ntchito popanga mafakitale opangira mankhwala opangira mapiritsi ndi makapisozi. Komabe, magwiridwe ake opanga mafilimu amakhala otsika pang'ono ku HPMC.

4.
Methylcellulose ndiyabwino kwambiri ndipo ndichilengedwe chomwe chili ndi mankhwala ovulaza. Izi zimapangitsa kukhala koyenera kwa chakudya ndi malo odzikongoletsa.

Kuyerekeza pakati pa HPMC ndi MC:

1. Solubility:
HPMC imasungunuka m'madzi kuposa methylcelulose. Kusiyana kosinthikaku kumapangitsa kuti hpmc njira yothandiza kwambiri mafakitale omwe amafunikira mosungunuka kwakukulu, monga zomanga.

2. Makutu:
Onse a HPMC ndi methyllulose amakhala ndi ma viscosies apamwamba. Komabe, mamasukidwe a HPMC ndi okwera pang'ono kuposa a methylcellulose. Izi zimapangitsa kuti mafakitale a HPMC omwe amagwiritsa ntchito m'mafakitale omwe amafunikira ma viscossies apamwamba, monga chakudya ndi zodzoladzola.

3. Mapangidwe a filimu:
HPMC ndi methylcellulose ndi onse opanga mafilimu. Komabe, HPMC ili ndi katundu wopanga mafilimu pang'ono kuposa methylcelulose, ndikupangitsa kukhala koyenera kugwiritsa ntchito malonda opangira mankhwala.

4. Madzi:
HPMC ndi methylcellulose zonse ndi zinthu zauzimu zapamwamba zomwe sizikhala ndi mankhwala ovulaza.

Hydroxypylth methylcellulose ndi methyllulose onse ndi ofunikira ma cellulose omwe amagwiritsidwa ntchito m'mafakitale osiyanasiyana. Makina onsewa amakhala ndi kusinthika kwakukulu, maonedwe apamwamba, katundu wopangidwa ndi mawonekedwe ndi ungwiro wokwanira. Komabe, kusakoloka ndi ufa wa HPMC kuli kwakukulu pang'ono kuposa omwe a methylclulose, ndikupangitsa kukhala koyenera kwambiri kwa mafakitale ofunikira kususuka kwambiri ndikuwoneka. Kuphatikiza apo, HPMC ili ndi katundu wopangidwa pang'ono ndi methylcelulose, ndikupangitsa kukhala koyenera kugwiritsa ntchito malonda opangira mankhwala. Komabe, zinthu zonsezi zimakhala ndi zinthu zapadera zomwe zimawapangitsa kuti azigwiritsidwa ntchito bwino kugwiritsa ntchito mafakitale osiyanasiyana, ndipo kugwiritsa ntchito kwawo kuyenera kutsimikizika molingana ndi pulogalamu inayake.
