Ubale Pakati pa Kusungidwa kwa Madzi kwa Hydroxypropyl Methyl Cellulose ndi Viscosity ndi Kutentha

Kuchuluka kwa madzi a hydroxypropyl methylcellulose kumatengera zomwe zili mu hydroxypropyl. Pazifukwa zomwezo, mphamvu yosungira madzi ya hydroxypropyl methylcellulose imakhala yamphamvu, ndipo methoxy yomwe ili mu hydroxypropyl yomweyi imachepetsedwa moyenera. . Kukwera kwa hydroxypropyl methylcellulose, kumapangitsanso kukhuthala kwake, kotero posankha chinthu, muyenera kusankha chomwe chimakuyenererani molingana ndi cholinga cha mankhwalawa.

Kutentha ndi zinthu zina zimakhudza kusungidwa kwa madzi kwa hydroxypropyl methylcellulose.

Kutentha kwa gel osakaniza:
Cellulose etha HPMC ali mkulu matenthedwe kutentha gelation ndi kusunga madzi bwino; m'malo mwake, ili ndi kusasunga bwino kwa madzi.

Kukhuthala kwa cellulose ether HPMC:
Pamene mamasukidwe akayendedwe a HPMC akuwonjezeka, kusungirako madzi ake kumawonjezeranso; pamene mamasukidwe akayendedwe ukuwonjezeka kumlingo, kuwonjezeka madzi posungira amachepetsa.

Selulosi ether HPMC homogeneous:
HPMC ali yunifolomu anachita, yunifolomu kugawa methoxyl ndi hydroxypropoxyl, ndipo ali bwino posungira madzi.

Cellulose ether HPMC mlingo:
Mlingowo ukachulukirachulukira, m'pamenenso kuchuluka kwa kusungirako madzi kumakwera komanso kumapangitsa kuti madzi asungidwe.

Pamene ndalama zowonjezera ndi 0.25 ~ 0.6%, kuchuluka kwa madzi osungira madzi kumawonjezeka mofulumira ndi kuwonjezeka kwa ndalama zowonjezera; pamene kuchuluka kwa madzi kumawonjezeka, kuwonjezeka kwa chiwerengero cha madzi osungira madzi kumachepa.

Mwachidule, kusungirako madzi kwa HPMC kumagwirizana ndi zinthu monga kutentha ndi kukhuthala, ndipo kusungirako madzi kumagwirizana ndi kuchuluka kwa hydroxypropyl methylcellulose yowonjezera. Pamene kuchuluka kwa hydroxypropyl methylcellulose kufika pamtengo wina, ntchito yake yosungira madzi imafika pamlingo.
