Hydroxypropyl methylcelulose, 28-30% methoxyl, 7-12% hydroxypypyl

Zolemba "28-30% methoxyl" ndi "7-12% hydroxypyl" amatanthauza kuchuluka kwa zolowa m'maloHydroxypypyl methylcellulose(Hpmc). Makhalidwewa akuwonetsa kuti pereliluse polymer yakhala yosinthidwa ndi methoxyl ndi ma hydroxypyl m'magulu.

1. 28-30% Methoxyl:
   • Izi zikuwonetsa kuti, pafupifupi, 28-30% yamagulu oyamba a hydroxyl pa celluluse alowa m'malo mwa magulu a methoxyl. Magulu a methoxyl (-Och3) amadziwitsidwa kuti awonjezere hydrophobity wa polymer of the Polymer.
2. 7-12% hydroxypyl:
   • Izi zikutanthauza kuti, pafupifupi, 7-12% ya magulu oyamba a hydroxyl pa molekyulu ya cellulose alowetsedwa ndi magulu a hydroxypyl. Magulu a hydroxypyl (-och2choch3) amadziwitsidwa kuti amalimbikitse kusungunuka madzi ndikusintha zinthu zina zakuthupi ndi mankhwala a polymer.

Mlingo wazolowa m'malo umakhudza katundu wa HPMC ndi magwiridwe ake munthawi zosiyanasiyana. Mwachitsanzo:

• Zambiri za methoxyl nthawi zambiri zimawonjezera hydrobicicity ya polymer ya polima, ikukhudza madzi ake osungunuka ndi zina.
• Zolemba zapamwamba za hydroxypyl zimatha kukulitsa kusungunuka kwamadzi ndikupanga mafilimu a HPMC.

Izi ndizofunikira kwambiri pakugwiritsa ntchito HPMC kuti mukwaniritse zofunika kwambiri m'mafakitale osiyanasiyana. Mwachitsanzo. M'makampani omanga, imatha kusintha madzi osungira ndi kutsatira zinthu za simenti.

Opanga amatulutsa makeke osiyanasiyana a HPMC yokhala ndi madigiri osiyanasiyana kuti akwaniritse zosowa zosiyanasiyana za mapulogalamu osiyanasiyana. Mukamagwiritsa ntchito hpmc mu mapangidwe, ndikofunikira kuti opanga apangidwe kuti aganizire kalasi ya HPMC yomwe imagwirizana ndi zomwe mukufuna ndi zomwe mukufuna.
