Hydroxypropyl methylcellulose (HPMC)he non-ionic cellulose ether i hoʻohana nui ʻia i ka meaʻai, ka lāʻau lapaʻau, ke kūkulu ʻana a me nā māla ʻē aʻe. Hana ʻia ia mai ka cellulose kūlohelohe ma o ka hana kemika e like me ka alkalization a me ka etherification, a loaʻa iā ia nā hiʻohiʻona nui:
4. Kaiapuni a me ka biocompatibility
Palekana kaiapuni: ʻO ka HPMC kahi mea biodegradable e pili ana i ke kaiapuni.
Palekana olaola: Ma ke ʻano he meaʻai a me nā mea hoʻohui lāʻau, loaʻa iā ia ka biocompatibility maikaʻi a ʻaʻohe mea ʻawaʻawa a maikaʻi ʻole.
5. Hoʻoponopono i nā waiwai kino
Hiki ke hoʻololi ʻia nā waiwai o HPMC (e like me ka viscosity a me ka mahana gel) ma o ka hoʻoponopono ʻana i kona degere o ka hoʻololi ʻana (ka ʻike o nā hui methoxy a me hydroxypropyl) e hoʻokō i nā koi noi like ʻole.
6. Ke kū'ē kemika
Paʻakai paʻakai: Paʻa ia i loko o kekahi ʻano o ka hoʻonā paʻakai.
ʻO ke kūpaʻa Enzymatic: Ke hoʻohālikelike ʻia me ka cellulose kūlohelohe, ʻoi aku ka ikaika o ka HPMC i ka hydrolysis enzymatic.
Hydroxypropyl methylcellulose ua hoʻohana nui ʻia i nā ʻoihana he nui e like me ka meaʻai, ka lāʻau lapaʻau, a me ke kūkulu ʻana ma muli o kāna mau waiwai kino a me nā kemika, nā hiʻohiʻona multifunctional, a me ka hoʻohana ākea. ʻO kona hiki ke hoʻoheheʻe ʻia i ka wai, ka mānoanoa, ka paʻa ʻana o ka wai, a me nā waiwai hana kiʻiʻoniʻoni e lilo ia i mea hiki ʻole ke hoʻololi a koʻikoʻi.
