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.
