Ikike njide mmiri nke hydroxypypylthyth na-adabere na ọdịnaya mmiri hydroxypyl. N'okpuru otu ọnọdụ ahụ, ikike mmiri nke dị elu nke hydropyythylthyl na-esikwu ike, na methoxy ọdịnaya nke otu ihe hydroxypyl belatara. . Ihe dị elu na ọdịnaya hydyypylthylcelllose, kawanye viscosity, yabụ mgbe ị na-ahọrọ ngwaahịa, ị ga-ahọrọ ngwaahịa nke dabara gị dị ka ebumnuche nke ngwaahịa ahụ.
Ọnọdụ okpomọkụ na ihe ndị ọzọ na-enwe mmetụta na njigide mmiri nke hydropyylthylthylthylthylthylthylthylthylthylthyl methylcelllose.
Igwe ikuku gel:
Cell na-ahụ maka HPMC nwere oke ikuku na nnukwu njide mmiri; Kama nke ahụ, ọ nwere njide mmiri na-adịghị mma.
Viscosis nke cellose hpmc:
Mgbe viscits of HPMC na-abawanye, njigide mmiri ya na-abawanye; Mgbe ndị viscitty na-abawanye n'otu oge, mmụba nke njigide mmiri na-ebelata.
Cellulose ether Hpmc homogeneous:
HPMC nwere mmeghachi omume nke edo, nkesa nke methoxyl na hydroxPropoxyl, ma nwee ezigbo nchekwa mmiri.
Cellulose ether HPMC usoro:
Ka ị na-enwe usoro ọgwụgwọ, ka elu mmiri na-egbochi mmiri na nsonaazụ mmiri na-apụta ìhè karị.
Mgbe mgbakwunye ego dị 0.25 ~ 0.6%, ọnụnọ mmiri na-abawanye ngwa ngwa na mmụba nke mgbakwunye ego ahụ; Mgbe mgbakwunye ego na-abawanye n'ihu, mmụba nke ọnụego mmiri nke mmiri na-akwụsịlata.
Na nkenke, njigide mmiri nke HPMC bụ ihe metụtara ihe dị ka okpomọkụ na vionsdị mmiri ya, yana njigide mmiri ya metụtara ihe hydropyylthylthyl. Mgbe ego nke hydroxylthylthylcelllose na-erute ezigbo uru, arụmọrụ mmiri ya ruru nguzozi.
