IHydroxypropyl Methylcellulose HPMC E3, E5, E6, E15, E50, E4M

IHydroxypropyl Methylcellulose (HPMC) i-cellulose ether enamabanga ahlukahlukene, ekhonjwa ngezinhlamvu nezinombolo. Lawa mabanga amele ukucaciswa okuhlukene, okuhlanganisa ukuhluka kwesisindo samangqamuzana, okuqukethwe kwe-hydroxypropyl, kanye ne-viscosity. Nakhu ukuhlukaniswa kwamabanga e-HPMC owashilo:

1. I-HPMC E3:
   • Leli banga kungenzeka libhekisele ku-HPMC ene-viscosity ethize 2.4-3.6CPS. Inombolo 3 ikhombisa i-viscosity yesisombululo se-aqueous esingu-2%, futhi izinombolo eziphakeme ngokuvamile zibonisa i-viscosity ephakeme.
2. I-HPMC E5:
   • Ngokufanayo ne-E3, i-HPMC E5 imele ibanga elihlukile le-viscosity. Inombolo 5 ibonisa i-viscosity eseduze 4.0-6.0 CPS yesisombululo se-aqueous esingu-2%.
3. I-HPMC E6:
   • I-HPMC E6 ingelinye ibanga elinephrofayili ye-viscosity ehlukile. Inombolo 6 isho i-viscosity 4.8-7.2 CPS yesisombululo se-2%.
4. I-HPMC E15:
   • I-HPMC E15 cishe imele ibanga eliphakeme le-viscosity uma liqhathaniswa ne-E3, E5, noma i-E6. Inombolo engu-15 ikhombisa i-viscosity 12.0-18.0CPS yesisombululo esinamanzi esingu-2%, iphakamisa ukufana okukhulu.
5. I-HPMC E50:
   • I-HPMC E50 ikhombisa izinga eliphezulu le-viscosity, nenombolo engu-50 emele i-viscosity 40.0-60.0 CPS yesixazululo esingu-2%. Leli banga kungenzeka libe ne-viscosity ephezulu kakhulu uma kuqhathaniswa ne-E3, E5, E6, noma i-E15.
6. I-HPMC E4m:
   • U-“m” ku-E4m ngokuvamile ubonisa i-viscosity emaphakathi 3200-4800CPS. I-HPMC E4m imele ibanga elineleveli ye-viscosity emaphakathi. Ingase ilungele izinhlelo zokusebenza ezidinga ibhalansi phakathi kwe-fluidity nokujiya.

Lapho ukhetha ibanga le-HPMC kuhlelo lokusebenza oluthile, okucatshangwayo kufaka phakathi i-viscosity oyifunayo, ukunyibilika, nezinye izici zokusebenza. I-HPMC ijwayele ukusetshenziswa ezimbonini ezifana nezokwakha, ezemithi, izimonyo, nokudla.

Ekudleni, i-HPMC ivamise ukusetshenziswa njengesengezo emikhiqizweni engasekelwe obisini ukuze kuthuthukiswe izakhiwo ezifana nokugcinwa kwamanzi, ukusebenza kahle, nokunamathela. Kwezemithi nezimonyo, i-HPMC isetshenziselwa ukwakha ifilimu nokujiya.

Kubalulekile ukuthintana nomkhiqizi noma umphakeli ukuze uthole ulwazi oluningiliziwe lwezobuchwepheshe, okuhlanganisa imininingwane nezicelo ezinconyiwe zebanga ngalinye le-HPMC. Abakhiqizi ngokuvamile bahlinzeka ngamashidi edatha yobuchwepheshe kanye nemibhalo yomkhiqizo ukuze uqondise abasebenzisi ekukhetheni ibanga elifaneleka kakhulu lezidingo zabo ezithile.
