ʻO HydroxyBopypopkōplose (HPMC) kahi mea hoʻokūkū plymer polymer ka nui i hoʻohana pinepineʻia ma ka lāʻau lapaʻau, ka uluʻana, nā kumuwaiwai, nā kumuwaiwai a me nāʻano'ē aʻe. Loaʻa ia i ka wai momona maikaʻi loa, nā waiwai kūpono, a me ka hoʻomauʻana, no laila he mea nui ia ma nāʻoihana likeʻole. I mea e hōʻoia ai i konaʻano a me ka maʻemaʻe, pono ke hōʻoia kūpono. ʻO nā mea e loaʻa ana he mauʻano maʻalahi no ka hydroxypoppploflolose
1. Nānā nānā
ʻO HPMC ka maʻamau ma ke keʻokeʻo i ke keʻokeʻo a iʻole ka nui o ka pwder keʻokeʻo a iʻole nā meaʻala, a me kaʻonoʻole. Ma ka nānāʻana i kona helehelena, hiki iāʻoe ke hoʻoponopono mua i ka hoʻoponoponoʻana inā he hoʻomaʻemaʻeʻiaʻo HPMC. ʻO kekahi hoʻololi hoʻololi a iʻole ke heleʻana o nā mea hōʻeha e hōʻikeʻia e hōʻike ana i keʻano he maʻi a iʻole ka haumia.
2. Mālama i ka hōʻoia
Ua loaʻa iā HPMC maikaʻi maikaʻi,ʻoi aku ka nui o ka wai. E kau i kahi liʻiliʻi o nā hiʻohiʻona i loko o ka wai a hoʻoulu mālie. Inā hiki iā ia ke hoʻokaʻawale wikiwiki a hana i kahi hopena collidal uniform ʻO ka wikiwiki o ka hoʻohemoʻana a me ka viscosity o ka hopena e pili ana i ke kaumaha o ka molmc a me nā hui o nā hui hydroxyprockl a me nā hui o ka hydrox
I ka manawa like, hiki ke hoʻohanaʻia ka palekana o HPMC i nā mea hoʻokele organik e hiki ke hoʻohanaʻia e like me kahi kūlanaʻike. Hoʻokomoʻiaʻo HPMC i ka hapanui o nā mea hana kūlohelohe (e like me Acetone, ethanol, etc.) Hiki ke hōʻoia houʻia kēiaʻano ma o ka ho'āʻoʻana i kāna mea kūpono i nā mea kūpono kūpono.
3.ʻO ka Spectrosrecopy (Ir)ʻike
Hoʻokomoʻia ka Spectroscopy (Ir) i kahi meaʻike pololei e hiki ai ke kōkua i ke kōkuaʻana i ka hōʻoiaʻana i keʻano molmc. ʻO ka hiʻohiʻona koʻikoʻi o HPMCʻo ia ka hoʻopiliʻana o nā pūʻulu e like me ka mityll (-ch3) a me hydrosybopyl ( Hiki ke hōʻoiaʻia ka heleʻana o kēia mau hui e ka poʻe i ka absorption o ka spectrum.
ʻO nā mea i hoʻopiliʻia e pili ana i nā peaks o ka hpmc a hpmc
2920 cm-1 (ch scching vibration)
1450 CM-1 (CHONING RIBRARS)
1100-1200 CM-1 (COC PRIT SHOTER)
3400 cm-1 (oh (Oh stching vibration, e loli paha ka waiwai o ka piak ma muli o ke alo o ka wai)
Ma ka hoʻohālikelikeʻana i ka SPE Spectrum o ka hua'ōlelo HPMC maʻamau, hiki iā ia ke hoʻohālikelikeʻia me keʻano o ka hōʻikeʻikeʻole e hōʻoia i keʻano o ka hoʻohālike.
4.ʻO kaʻikeʻana i keʻano hoʻohālikelike
HPMC, e like me kahi mea eter coupound, ua loaʻa i nā hiʻohiʻona o ka pono o nā mea kanu a hiki ke hōʻikeʻia e nā hopena maʻalahi.
(1) Ka hopena ma lalo o nā kūlana Acidic:
E hoʻokaʻawale i kahi liʻiliʻi o HPMC i ka wai, e hoʻohui i ka dilita hydrochlopric acid, a me ka wela. Inā loaʻa kahi mea kohu i loko o ka hopena,ʻo ia ka mea e loaʻa iā hpmc. Hiki keʻikeʻia kēia hopena e ka paʻaʻana o ka paʻaʻana o ka hydroxyproopsl a me nā hui mityl ma lalo o nā kūlana Acidic.
(2) Ka hopena ma lalo o nā kūlana alkaline: HPMC i ka wai i ka wai e hana ai i kahi hopena colloidal. ʻAʻole maʻalahi ia e hoʻokaʻawale i lalo o nā kūlana alkaline (e like me ka sodium hydroxide sult), e pili ana i kona mau hydrophinicity a me ka hydrogel. Inā he turbid ka hopena a iʻole i ka manawa,ʻo ia keʻano o ka hpmc i kēia manawa.
5.ʻO kaʻikeʻia e Viscosity Greection HPMC he mea waiwai me nā hiʻohiʻona viscosity, no laila hiki keʻikeʻia e kona viscosity i loko o keʻano o ka s viscosity. ʻO ka'ōlelo maʻamau, e hanaʻo Hpmc i nāʻano kala me kekahi mea kīwaha ma hope o ka neʻeʻana i loko o ka wai mole.
I mea e pono ai e ana i ka viscosity, hiki ke anaʻia ka hopena o ka hpmc E like me ke kaumaha o ka molcular o ka HPMC a me ka loaʻaʻana o ka hopena, hiki ke kohoʻia kāna viscosity. Inā he haʻahaʻa loa ka viscosity o keʻano o ka hoʻohālike ma mua o ka hopena HPMC maʻamau, e hōʻike ana he haʻahaʻa paha keʻano o ka molena.
6. Menging Point / Decomposition Point Guction HPMC, e like me keʻano kiʻekiʻe o ka molcular I ka wā i hāpaiʻia aiʻo hpmc, hiki ke nānāʻia kona mau loli i nāʻano likeʻole. ʻO ka'ōlelo lehulehu, e hoʻomaka anaʻo HPMC e hoʻopaʻi i ka makahiki 180-200 ℃, e hoʻokuʻu ana i kekahi mau mea kanu lāʻau (e like me nā wai a me nā wai a me nā wai. Hiki i ka hoʻololi i keʻano Decomposition e hiki ke hōʻoia hou inā he kumumanaʻo e hoʻomaʻemaʻeʻiaʻo HPMC.

ʻO ka hopena i hanaʻia ma hope o ka haʻaleleʻana o HPMC i kahi haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa. Hiki ke anaʻia ka pae o ka pae o ka hpmc e hoʻohana i ka hoʻohanaʻana i kahi papa kiʻekiʻe a iʻole keʻano o keʻano. Inā hoʻokūkū ia i ka'ā'ī o ka pae o ka hopena o ka hopena maʻamau,ʻo ia ka mea i manaʻoʻia he hpmc.
Ua hoʻolauna i ka mea i luna aʻe a me nāʻano maʻalahi no ka hoʻomaopopoʻana i ka hydroxyproopulose (hpmc). Hoʻomaopopo kēia mau hana i ka HPMC mai nā kihi he nui e like me keʻano, e pili ana i ka hōʻoiaʻana, etc.
