HPMC (hydroxyproopyl milllcellse) a me Hec (hydroxyethyl cellulose)
1
ʻO HPMC a me Hecʻo ia ka mea e hanaʻia ai nā keiki kāne i keʻano kūlohelohe (e like me ka cotton a iʻole ka lāʻau lāʻau a iʻole nā lāʻau lāʻau.
ʻO HPMC (hydroxyproopyl middlelllose): hpmc i loaʻa i kahi'āpana a iʻole ke hoʻololiʻana i kekahi o nā hui hydrolsel (-ch₃ch (-ch₃ch ʻO ke kiʻekiʻe o ka hoʻololiʻana o ka huiʻana o MYTYL a me HydroxyPyl i nā hui o HPMC.
Hec (hydroxyethyl cellulouse)
ʻO kēia mauʻokoʻa i keʻano o keʻano e pili pono ana i kā lākou palena,ʻo Viscosity, a me nā waiwai pilikino a me nāʻano kino.
2. Mālama a me nā kūlana paʻakikī
HPMC: Ua loaʻa iā HPMC Hiki ke hoʻopauʻia i ka paleʻana o nā mea hoʻonaʻauao i like me etanol, acetone, etc., akā, he kaʻe o ka neʻeʻana i pili i nāʻike i piliʻia. ʻO kahi hiʻohiʻona koʻikoʻi o HPMC ka mea e pale ai i ka wai anuanu,ʻo nā mea e hōʻeha ai i keʻano o ka gel i ka wā e hoʻomehana ai a me nā pale i ka wā e hoʻomoʻi ai i ka wā i hoʻomehanaʻia He mea nui loa kēia waiwai i nā mahina e like me ke kūkuluʻana a me nā kapa.
Hec: ua haʻalele hoʻiʻo ia i ka wai anuanu, akāʻaʻole like me ka meaʻole HPMC,ʻaʻoleʻo Hec i ka wai wela. No laila, hiki ke hoʻohanaʻiaʻo Hec ma luna o kahi ākea ākea. Loaʻa iā Hec ka paʻakai paʻakai a me nā waiwai nui a he kūpono no ka hoʻohanaʻana i nā hopena e pili ana i nā electrolytes.
3.ʻO Viscosity a me nā waiwai Rheological
ʻO ka mākaʻikaʻi o ka HPMC a me Hec i hoʻololi me ko lākou mau molela, a he mau hopena nui aʻelua mau hopena maikaʻi loa ma nāʻano likeʻole.
HPMC: HPMC hōʻike i nā Pseudoplatic kiʻekiʻe Ua emi ka viscosity o HPMC i ka wā e hoʻonui ai iā lākou, e hana ana i nā noi, e like me ka hoʻonuiʻana o ka HPMC
Hec: He nui nā mea kōkua hec e loaʻa ai nā mea kūʻai aku a me nā waiwai nui loa i nā kumukūʻai haʻahaʻa haʻahaʻa loa. Eia kekahi, he mau mea kōkuaʻo Hec i nā loli liʻiliʻi i nā wahi i loaʻa i nā paʻakai a me nā electrolytes maikaʻi. Ua hoʻohana nuiʻia lākou i nā mahina e pono ai i ke kūʻana o ka paʻakai
4. Nāʻokoʻa ma nā kahua noi
ʻOiaiʻo ka HPMCʻelua a hec hiki ke hoʻohanaʻia e like me nā mea he nui, nā kiʻiʻoniʻoni, sublilizers, etc..
Nā noi o HPMC:
Hoʻohanaʻia nāʻoihana hana Ua hoʻomaikaʻiʻo ia i ka hanaʻana o ka paila, e kū ana i ka laweʻana, a me ka prolongs i ka manawa ākea o ka papa.
Nā Kūlana Kūʻai a me nā Waiwai I loko o kaʻoihana meaʻai, hoʻohanaʻiaʻo Hpmc he mea liʻiliʻi e like me ka mea e hoʻonui ai i ka meaʻai,ʻo ia nō ka mea emulsifier,ʻo Shaickener, a me ka Stabilizer.
Ua hoʻohanaʻia kaʻoihana maʻamau: Ua hoʻohanaʻiaʻo HPMC ma keʻano he stibilizer e like me keʻano o nā mea hoʻonaninani, a me ka mālamaʻana i nā huahana pilikino.
Nā noi o hec:
ʻO ke kumukūʻai aila: Mai ka hec i kahi e pono ai keʻano o ka paʻakai, kūpono ia no ka hoʻohanaʻana i nā mea hoʻonaninani i nā wahi nui o ka'ōpala.
Hoʻohanaʻia: Ua hoʻohanaʻiaʻo Hec ma keʻano he shaicerner a stabilizer i nā lole wai-wai. Hiki iā ia ke hoʻomaikaʻi i keʻano o ka uluʻana a me ka hanaʻana i ka hanaʻana o ka papaʻaina a pale i ka papaʻiʻana mai ka laweʻana.
ʻO ka pepa pepa a me nāʻoihana uila
5.ʻO ke kūpaʻa kūlohelohe a me ka biocomopibility
HPMC: Ua hoʻohana pinepineʻiaʻo HPMC i loko o nā māla lāʻau lapaʻau a me nā meaʻai meaʻai ma muli o kāna biocompatibility maikaʻi a me ka biodegratability maikaʻi. ʻO kāna mau mea hoʻonaninani e hāʻawi aku ai i nā mea pono kūʻokoʻa i kekahi mauʻano o nā kumu lāʻau lapaʻau. Eia kekahi,ʻo Hpmc,ʻoʻoleʻo Hpmc,ʻaʻole i hikiʻole e nā electrolytes, a ua paʻa maikaʻi ke loli.
Hec: Hec maikaʻi hoʻiʻo Hec biocompatible a me ka biodegralitiblity No laila, he koho maikaʻiʻo Hec kahiʻoi aku ka maikaʻi o ka paleʻana o ka paʻakai a me ke kauaʻana, e like me ka mīkini hana hoʻokipa, etoc.
6. Uku a me ka lako
Mai ka loaʻaʻana o ka HPMC a me Hec i loaʻa mai keʻano kūlohelohe,ʻo ka lako o nā mea hana, akā ma muli o keʻano hana hana likeʻole ma mua o ka hec. Hana hou kēia i nā mea i hoʻohana nuiʻia ma kekahi mau noi noi-koi, e like me ke kūkuluʻana i nā mea kūkulu, etc.
ʻO HPMC a me Hec he nui nā derivatives celouluse nui. ʻOiai lākou heʻokoʻa i loko o keʻano lāʻau, he mau hana lāua e like me ka shuckening, stabilization, ka hanaʻana i ka wai. I nā'ōlelo o ke koho noi noi,ʻo HPMC i noho i kahi kūlana koʻikoʻi ma ka hoʻomākaukauʻana i ka hana maʻamau ʻOiaiʻo Hec ke pāʻani nei i kahi hana koʻikoʻi i loko o kaʻoihana petroleum ma muli o konaʻano paʻakai paʻakai maikaʻi loa a me nā mea kūpono. ʻOi aku ka maikaʻi o ka mining a me nā lole wai-wai. Wahi a nā koi noi likeʻole, ke kohoʻana i nā derivatives kūpono kūpono e hiki ke hoʻomaikaʻi i nā pono huahana a me nā pono waiwai.
