Kusiyana pakati pa instant hypromellose ndi hot soluble hypromellose

Pakadali pano, hydroxypropyl methylcellulose pamsika wapakhomo amagawidwa kukhala mtundu wosungunuka (womwe umatchedwanso mtundu wosungunula pang'onopang'ono) ndi mtundu wosungunula nthawi yomweyo, ndipo mtundu wosungunula wotentha ndiwonso wamba komanso wogwiritsidwa ntchito kwambiri pa cellulose.

Hot-melt (slow-melt) hydroxypropyl methylcellulose HPMC sinachiritsidwe ndi glyoxal.Ngati kuchuluka kwa glyoxal kuli kwakukulu, kubalalitsidwa kudzakhala kofulumira, koma kukhuthala kumawonjezeka pang'onopang'ono, ndipo ngati ndalamazo ndizochepa, zosiyana zidzakhala zoona.Hydroxypropyl methylcellulose HPMC idzasonkhana pamodzi ikakumana ndi madzi ozizira (koma izi zidzasungunuka pang'onopang'ono, koma zimatenga nthawi yaitali.), Koma zimafalikira mofulumira m'madzi m'madzi otentha mpaka Zizimiririka m'madzi, ndipo kukhuthala kwake kumawonjezeka. pang'onopang'ono pamene kutentha kumatsika pang'onopang'ono mpaka kumakhala madzi owoneka bwino a viscous.Chodabwitsa chake ndi chofanana ndi kusungunuka kwa ma cellulose apamwamba kwambiri a sodium carboxymethyl.Pamene mapadi a cellulose kunja kwa madzi amasungunuka, amakhala viscous, ndiyeno amakulunga mapadi mkati omwe sanakhudze madzi, koma Izi zidzasungunukanso pang'onopang'ono, koma zidzatenga nthawi yaitali.

Instant-type hydroxypropyl methylcellulose HPMC imayikidwa pamwamba ndi glyoxal.Amabalalika mofulumira m’madzi ozizira, koma samasungunuka kwenikweni.Zimatenga nthawi kuti mamasukidwe ake awonekere, chifukwa amangofalikira m'madzi koyambirira, zomwe siziri zofunikira kwenikweni.Pakuti kuvunda pamwamba, mamasukidwe akayendedwe kufika pazipita mtengo pafupifupi mphindi makumi anayi.Pamene mamasukidwe akayendedwe akukwera, njira yamadzimadzi imakhala yomveka bwino komanso yowonekera, yomwe ndiyo kusungunuka kwenikweni.Instant-type hydroxypropyl methylcellulose HPMC imagwiritsidwa ntchito m'makampani enaake ndipo sichidzasakanizidwa ndi ufa wouma, kapena ikafunika kusungunuka ndipo madzi otentha sangathe kugwiritsidwa ntchito chifukwa cha zipangizo ndi zifukwa zina, hypromellose Cellulose-based solution. ku vuto lovuta chotero.
