Pilina ma waena o ka paʻa ʻana o ka wai o Hydroxypropyl Methyl Cellulose a me ka Viscosity a me ka mahana

ʻO ka hiki ke mālama i ka wai o ka hydroxypropyl methylcellulose e pili ana i ka nui o ka hydroxypropyl. Ma lalo o nā kūlana like, ʻoi aku ka ikaika o ka hiki ke mālama i ka wai o ka hydroxypropyl methylcellulose kiʻekiʻe, a ua hoʻemi kūpono ʻia ka nui o ka methoxy o ka nui o ka hydroxypropyl. . ʻO ke kiʻekiʻe o ka nui o ka hydroxypropyl methylcellulose, ʻoi aku ka nui o kona viscosity, no laila i ke koho ʻana i kahi huahana, pono ʻoe e koho i ka huahana kūpono iā ʻoe e like me ke kumu o ka huahana.

Loaʻa ka hopena o ka mahana a me nā kumu ʻē aʻe i ka paʻa ʻana o ka wai o ka hydroxypropyl methylcellulose.

Mahana gel wela:
He kiʻekiʻe ka mahana gelation thermal o ka Cellulose ether HPMC a me ka paʻa wai maikaʻi; ma ke ʻano ʻē, he paʻa wai maikaʻi ʻole ia.

ʻO ka mānoanoa o ka cellulose ether HPMC:
Ke piʻi ka mānoanoa o HPMC, piʻi pū kekahi kona paʻa wai; ke piʻi ka mānoanoa i kekahi ʻano, e emi ana ka piʻi ʻana o ka paʻa wai.

ʻO ka cellulose ether HPMC homogeneous:
He ʻano like ka hopena o ka HPMC, ka hoʻolaha like ʻana o ka methoxyl a me ka hydroxypropoxyl, a he maikaʻi ka paʻa ʻana o ka wai.

Ka nui o ka cellulose ether HPMC:
ʻO ka nui o ka mahele lāʻau, ʻoi aku ke kiʻekiʻe o ka nui o ka paʻa ʻana o ka wai a ʻoi aku ka maopopo o ka hopena o ka paʻa ʻana o ka wai.

Ke piʻi koke ka nui o ka hoʻohui ʻana he 0.25~0.6%, e piʻi koke ka nui o ka paʻa ʻana o ka wai me ka piʻi ʻana o ka nui o ka hoʻohui; ke piʻi hou aku ka nui o ka hoʻohui, e lohi ana ke ʻano o ka piʻi ʻana o ka nui o ka paʻa ʻana o ka wai.

I ka pōkole, pili ka paʻa ʻana o ka wai o HPMC i nā mea e like me ka mahana a me ka mānoanoa, a pili kona paʻa ʻana o ka wai i ka nui o ka hydroxypropyl methylcellulose i hoʻohui ʻia. Ke hiki ka nui o ka hydroxypropyl methylcellulose i kahi waiwai, hiki i kāna hana paʻa wai i kahi kaulike.
