I-Hydroxypropylm methylcellulose hpmc e3, E5, E6, E15, E50, E4M

I-Hydroxypropyl Methylcellulose (HPMC) yi-ether ye-cellulose enamamaki ahlukahlukene, aboniswe ngezinhlamvu nezinombolo. Lawa mabanga amele ukucaciswa okuhlukile, okubandakanya ukuhlukahluka kwesisindo se-molecular, okuqukethwe kwe-hydroxypropyl, nokubonakala. Nakhu ukuwohloka kwamabanga we-HPMC owashilo:

1. I-HPMC E3:
   • Leli banga libhekisela ku-HPMC ngokubona okuthile 2.4-6cps. Inombolo 3 ikhombisa ukubonwa kwesisombululo esingamanzi esingu-2%, futhi izinombolo eziphakeme ngokuvamile zibonisa ukubonakala okuphezulu.
2. I-HPMC E5:
   • Ifana ne-E3, i-HPMC E5 imele ibanga elihlukile le-viscosity. Inombolo 5 ikhombisa ukubonakala okulinganiselwa ukuthi i-4.0-6.0 CPS yesisombululo esingamanzi esingu-2%.
3. I-HPMC E6:
   • I-HPMC E6 ingenye ibanga ngephrofayela ehlukile ye-viscosity. Inombolo 6 isho i-viscocity 4.8-7.2 CPS yesisombululo esingu-2%.
4. I-HPMC E15:
   • I-HPMC E15 imele ibanga eliphakeme le-viscosity liqhathaniswa ne-E3, E5, noma e6. Inombolo 15 ikhombisa i-viscocity 12.0-18.0cps yesisombululo esingamanzi esingu-2%, iphakamisa ukuvumelana okukhulu.
5. I-HPMC E50:
   • I-HPMC E50 ikhombisa ibanga eliphakeme le-viscosity, nenombolo 50 emele i-viscosity 40.0-60.0 CPS yesisombululo esingu-2%. Leli banga kungenzeka libe nokubonakala okuphezulu kakhulu ngokuqhathaniswa ne-E3, E5, E6, noma i-E15.
6. Hpmc e4m:
   • I- "M" ku-E4M ngokuvamile isho i-viscosity ephakathi 3200-4800CPS. I-HPMC E4M imele ibanga ngesilinganiso sokubona okulinganiselayo. Kungase kube lula ukuthola izinhlelo zokusebenza ezidinga ukulinganisela phakathi koketshezi nobukhulu.

Lapho ukhetha ibanga le-HPMC lesicelo esithile, ukucatshangelwa kufaka i-viscosity efiselekayo, i-solubity, nezinye izici zokusebenza. I-HPMC isetshenziswa kakhulu ezimbonini ezinjengezokwakha, ezemithi, izimonyo kanye nokudla.

Ekudleni, i-HPMC ivame ukusetshenziswa njengesengezo emikhiqizweni engeyona yobisi ukuthuthukisa izakhiwo njengokugcinwa kwamanzi, ukusebenziseka kanye nokunamathela. Emikhakheni kanye nezimonyo, i-HPMC isetshenziselwa ukwakheka kwayo kwakhiwa amafilimu nokuqina.

Kubalulekile ukuxhumana nomenzi noma umphakeli ukuthola imininingwane eningiliziwe yezobuchwepheshe, okubandakanya ukucaciswa nezinhlelo zokusebenza ezinconyiwe zebanga ngalinye le-HPMC. Abakhiqizi ngokuvamile bahlinzeka ngemininingwane yedatha yezobuchwepheshe kanye nemibhalo yomkhiqizo ukuqondisa abasebenzisi ekukhetheni ibanga elifanele kakhulu ngezidingo zabo ezithile.
