Mmekọrịta dị n'etiti njide mmiri nke Hydroxypropyl Methyl Cellulose na viscosity na okpomọkụ.

Ike njide mmiri nke hydroxypropyl methylcellulose dabere na ọdịnaya hydroxypropyl. N'okpuru otu ọnọdụ ahụ, ikike njigide mmiri nke hydroxypropyl methylcellulose dị elu na-esiwanye ike, na-ebelata ọdịnaya methoxy nke otu ọdịnaya hydroxypropyl nke ọma. . Ọdịnaya dị elu nke hydroxypropyl methylcellulose, ka viscosity ya dịkwuo ukwuu, yabụ mgbe ị na-ahọrọ ngwaahịa, ị ga-ahọrọ ngwaahịa dabara gị mma dịka ebumnuche nke ngwaahịa ahụ.

Okpomọkụ na ihe ndị ọzọ nwere mmetụta na njide mmiri nke hydroxypropyl methylcellulose.

Thermal Gel okpomọkụ:
Cellulose ether HPMC nwere okpomọkụ gelation dị elu na njigide mmiri dị mma; N'ụzọ megidere nke ahụ, ọ nwere njigide mmiri na-adịghị mma.

Viscosity nke cellulose ether HPMC:
Mgbe viscosity nke HPMC na-abawanye, njigide mmiri ya na-abawanye; mgbe viscosity na-abawanye ruo n'ókè ụfọdụ, mmụba nke njide mmiri na-ebelata.

Cellulose ether HPMC yiri:
HPMC nwere mmeghachi omume otu, nkesa methoxyl na hydroxypropoxyl otu, ma nwee ezigbo njide mmiri.

Cellulose ether HPMC usoro onunu ogwu:
Ka usoro ọgwụgwọ ahụ dịkwuo elu, ọnụ ọgụgụ njide mmiri dị elu na nke doro anya mmetụta njide mmiri.

Mgbe ego mgbakwunye bụ 0.25 ~ 0.6%, njigide mmiri na-abawanye ngwa ngwa na mmụba nke mgbakwunye ego; mgbe ego mgbakwunye na-abawanye n'ihu, mmụba na-arịwanye elu nke njide mmiri na-ebelata.

Na nkenke, njide mmiri nke HPMC metụtara ihe ndị dị ka okpomọkụ na viscosity, na njide mmiri ya na-ejikọta ọnụ ọgụgụ nke hydroxypropyl methylcellulose agbakwunyere. Mgbe ọnụọgụ hydroxypropyl methylcellulose ruru ụfọdụ uru, ọrụ njigide mmiri ya ruru nguzozi.
