ʻO ka mana paʻa wai o ka hydroxypropyl methylcellulose e pili ana i ka ʻike hydroxypropyl. Ma lalo o nā kūlana like, ʻoi aku ka ikaika o ka paʻa wai o ka hydroxypropyl methylcellulose kiʻekiʻe, a ua hoʻemi pono ʻia ka ʻike methoxy o ka hydroxypropyl maʻamau. . ʻOi aku ka kiʻekiʻe o ka hydroxypropyl methylcellulose, ʻoi aku ka nui o kona viscosity, no laila ke koho ʻana i kahi huahana, pono ʻoe e koho i ka huahana e kūpono iā ʻoe e like me ke kumu o ka huahana.
He hopena ka mahana a me nā mea ʻē aʻe i ka paʻa ʻana o ka wai o ka hydroxypropyl methylcellulose.
Ka wela wela gel:
ʻO ka cellulose ether HPMC he kiʻekiʻe ka wela wela a me ka paʻa wai maikaʻi; akā, he ʻino ka paʻa ʻana o ka wai.
ʻO ka viscosity o ka cellulose ether HPMC:
Ke piʻi ka viscosity o HPMC, piʻi pū ka paʻa wai; ke piʻi ka viscosity i kekahi ʻano, e emi ana ka piʻi ʻana o ka paʻa wai.
ʻO ka cellulose ether HPMC homogeneous:
Loaʻa i ka HPMC ka hopena like, ka hāʻawi like ʻana o ka methoxyl a me ka hydroxypropoxyl, a maikaʻi ka paʻa wai.
ʻO ka helu HPMC cellulose ether:
ʻOi aku ka nui o ka dosage, ʻoi aku ka kiʻekiʻe o ka pae paʻa wai a ʻoi aku ka maopopo o ka hopena paʻa wai.
I ka 0.25 ~ 0.6% ka nui o ka hoʻohui, piʻi wikiwiki ka nui o ka mālama ʻana i ka wai me ka piʻi ʻana o ka nui o ka hoʻohui; ke piʻi aʻe ka nui o ka hoʻohui, e lohi ka piʻi ʻana o ka nui o ka mālama ʻana i ka wai.
I ka pōkole, pili ka paʻa wai o HPMC i nā mea e like me ka mahana a me ka viscosity, a ʻo kona paʻa wai e pili ana i ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia. Ke piʻi ka nui o ka hydroxypropyl methylcellulose i kahi waiwai, hiki i kāna hana mālama wai i ke kaulike.
