Uyini umehluko phakathi kwe-methylcellosise ne-hpmc?

I-methylcellulose (MC) ne-Hydroxypropyll methylcellulose (HPMC) zombili zisetshenziswa okusetshenziswa okusetshenziswayo okuvame ukusetshenziswa kwe-cellulose, esetshenziswa kabanzi ekudleni, umuthi kanye nezinto zokwakha.

Isakhiwo samakhemikhali:
I-Methylcellose yenziwa nge-methylating cellulose futhi ikakhulukazi iqukethe amaqembu we-methyl.
I-HPMC isuselwe ku-methylcellulose futhi yethula amanye amaqembu ama-hydroxypropyl, okwenza kube ne-soubity engcono nokulungiswa kwe-viscosity.

I-Solubity:
I-methylcellulose ingakha i-colloid emanzini, kepha i-solubility yayo iphansi.
I-HPMC incane kakhulu emanzini, ikakhulukazi emanzini abandayo, akha isixazululo esibonakalayo.

Izici Zokubona:
I-methylcellulose inokuvuleka okuphezulu futhi ilungele izinhlelo zokusebenza ezidinga ukubopha okuqinile.
I-viscosity ye-HPMC ingalawulwa ngokulungisa izinga lokufaka esikhundleni se-hydroxypropyl, futhi uhla lwayo lwesicelo lubanzi.

Izindawo zohlelo lokusebenza:
I-methylcellose ivame ukusetshenziswa ekudleni kwabakhulu, amaphilisi wezidakamizwa, njll.
I-HPMC isetshenziswa kakhulu ezintweni zokwakha, izimbobo kanye namalungiselelo amakhamithi, ikakhulukazi lapho kudingeka u-fluodity.

Ukuqina okushisayo:
I-HPMC inokuqina okuphezulu okushisayo futhi ingagcina ukusebenza emazingeni okushisa aphezulu.
I-methylcellose ingahle ihlasele amazinga okushisa aphezulu, okuthinta ukusebenza kwayo.

I-methylcellulose ne-hpmc yehlukile kakhulu ekwakhiweni kwamakhemikhali, e-solubity, izici ze-viscosity, nezindawo zohlelo lokusebenza. Ukukhethwa kokuthi iziphi izinto okufanele zisetshenziswe kuzo kufanele kunqunywe ngokusekelwe kwizidingo ezithile zohlelo lokusebenza.
