ʻO HPMC ka maʻamau i kahi keʻokeʻo keʻokeʻo a iʻole paha i ke keʻokeʻo keʻokeʻo, na Hiki ke hoʻopauʻia i ka wai anuanu a me kekahi mau mea hana kūlohelohe (e like me nā mea e like me nā mea e like me ka etohanol Ma muli o konaʻano non-Inonic,ʻaʻole ia e hele i lalo o ka hopena electrolytic ma ka hopena kūponoʻole aʻaʻole nui e hoʻopilikia nuiʻia e ka waiwai ph.
2. Viscosity a me Rheology
ʻO HPMC AQUISUS SOMEFS kahi maikaʻi loa a me ka jhixotropy. ʻO nāʻanoʻano likeʻole o ka hopohopo i nā viscoriesctic®hpmc i nā viscosities likeʻole, aʻo ka pae maʻamau he 5 a 100000 mika ʻO kāna hoʻonā e hōʻike ana i ka pseudoplaticty
3, gelation thermal
I ka wā i ho'ālaʻia aiʻo HPMC i ka wai, ua emi ke kahe o ka hopena a me ka gel i hanaʻia ma kekahi mahana. Ma hope o ka holoiʻana, e hoʻi ka moku'āina i ka moku'āina. ʻO nāʻano likeʻole o HPMC i nāʻano likeʻole o Gel ma waena o 50 a me 75 ° C. He mea nui loa kēia waiwai i nā noi e like me ka hale kūʻai o ka papa hana a me nā mea kanu lāʻau lapaʻau.
4. Hana papa
No ka mea he mau molpc molecules i nā hui hydropphilic a me nā hui hydrophobic, hōʻike lākou i kahi hana a hiki ke pāʻani i kahi hana. ʻO ka laʻana, ma nā kapa, a me nā elima a me nāmuma: hiki i ka hrmc ke hoʻomaikaʻi i ke kūpaʻa o ka emunuson a pale aku i ka poʻe koa o ka hauoli.
5. Hygroscopity
Ua loaʻa iā HPMC kahi hygroscopicity a hiki ke hoʻopili i ka wai i loko o kahiʻano haʻahaʻa. No laila, aia i kekahi noi, pono e ukuʻia ka manaʻo no ka hoʻokaumahaʻana i ka kauʻana i ka mea i lilo i lalo a me ka ampshumeration.
6.ʻO ka waiwai o ka hoʻolālā
Hiki i ka HPMC ke hana i kahi kiʻi paʻakikī a me keʻano maʻamau,ʻo ia ka mea i hoʻohana nuiʻia ma ka meaʻai, lāʻau lapaʻau (e like me nā mea hana coating. ʻO keʻano, i loko o kaʻoihana hale kūʻai, hiki ke hoʻohanaʻiaʻo HPMC
7. Biocompatibility a me ka palekana
ʻAʻole maikaʻiʻo HPMC a me nā mea hōʻehaʻole, a hiki ke palekana maluhia e ka metabolilized e ke kino o ke kanaka, no laila ua hoʻohana nuiʻia i nā mahina o ka lāʻau lapaʻau a me nā meaʻai. E like me ka mea aloha pharmacetical, maʻamau ia e hana e hana i nā papa hana i hoʻokuʻuʻia, nā hale kūʻai cops

Ua paʻaʻo HPMC i loko o ka ph off o 3 a 11, aʻaʻole maʻalahi e hoʻokaʻawaleʻia e nā mea kanu a me nā kumuwaiwai kula
9, pale pale
Ua paʻaʻia ka hopena o HPMC i nā paʻakai ma loko
10.
Ua loaʻa ka hopohopo o ka hopohopo i nā wahi kiʻekiʻe ma keʻano kiʻekiʻe, akā hiki ke hōʻole aʻike paha i ka wā i hōʻikeʻia i nā kiʻekiʻe kiʻekiʻe. Hiki iā ia ke mālama i ka hana maikaʻi ma loko o kekahi mau mahana o kekahi mau mahana (ma lalo o 200 ° C), no laila he kūpono ia no nā noi o keʻano kiʻekiʻe.
11.
Hpmcua paʻa pono i ka mālamalama, nā mea waiwai a me nā mea maʻamau, aʻaʻole maʻalahi ia i nā mea i waho o nā mea i waho. No laila, hiki ke hoʻohanaʻia i nā huahana e pono ai nā huahana e pono ai e aʻoʻia nā mea kūʻai a me nā lāʻau lapaʻau.
Hoʻohana nuiʻia ka hydroxyprooparpoparlulose ma nāʻoihana he nui ma muli o kāna mau mea kūpono loa, heʻano hana a me keʻano o keʻano. I kaʻoihana kūkulu, ua hiki ke hoʻohanaʻia ma ka'āpanaʻo sihar i loko o kaʻoihana lāʻau lapaʻau, hiki ke hoʻohanaʻia e like me kaʻoliʻoli o ka lāʻau lapaʻau; i kaʻoihana meaʻai, he mea kanu maʻamau. ʻO ia kēia mau waiwai pilikino e hana i ka hpmc i kahi mea hana polmc hana nui.
