ʻO nā hiʻohiʻona Viscosity o ka hydroxypropopylll

Hydrexypropropsl hydrolcellse (HPMC)he mea nui i hoʻohana nuiʻia i ka wai wai-wai me nāʻano noi likeʻole, kūikawā i nā mea lapaʻau, meaʻai, nā huahana a me nā huahana cosmetic. ʻO kona hiki ke hana i ka laulā, Gel-E like me nā hopena e like me ka huiʻana me ka wai e hana ai i kahi mea hana vancestile. ʻO ka viscosity o nā wikiō kimacell®hpmc e pāʻani i kahi kūlana koʻikoʻi i ka hoʻoholoʻana i kā lākou hana ma nāʻano likeʻole. ʻO ka hoʻomaopopoʻana i nā hiʻohiʻona Viscosity o HPMC AQUITUS EXTENTIAL no ka hoʻomaikaʻiʻana i ko lākou hoʻohanaʻana i nāʻoihana'ē aʻe.

1. Hōʻikeʻike i ke hydroxxypopkōrpoparne (HPMC)

ʻO ka hydroxyprooppopplayl middlcelllose he semi-synthetic derivative of cellouse. Ua hanaʻia e ke ala o ka cellulose me nā hui hydroxyproopyl a me nā hui mityll. Hiki i ka pae o kēia mau mea koho ke ala i ke alakaʻiʻana i nā helu likeʻole o HPMC me nā hiʻohiʻonaʻokoʻa, me kaʻikeʻoleʻia. ʻO keʻano maʻamau o HPMC i kahi o ke poʻo cellulose a me nā hui hydroxyproopsl a me nā hui uila i hoʻopiliʻia i nā hui glucose.

Hoʻohanaʻiaʻo HPMC ma nāʻano o nāʻoihana ma muli o kona biocompatibility, hiki ke hana i nā mea kūʻai aku, a me ka maʻalahi o ka nohona i ka wai. I nā hoʻonā AQUISINS, HPMC e like me keʻano he meaʻole-iniha, ka wai wai wai-wai nui e pili ana i nā waiwai o ka hoʻonāʻana o ka hoʻonā

2. Nā hiʻohiʻonaʻike o nā hopena HPMC

ʻO ka viscosity o nā hopena HPMC e hoʻouluʻia e kekahi mau kumu, me ka neʻeʻana o ka hpmc, keʻano o ka polymer a me nā mea hou aku. Aia ma lalo nei nā mea nui e pili ana i nā hiʻohiʻona viscosity o HPMC ma HPMC i nā hoʻonā Aqueous:

Ka heleʻana o HPMC: Hoʻonui ka viscolisity e like me ka neʻeʻana o ka hpmc e hoʻonui. I nā mea kiʻekiʻe aʻe, nā molena HPMC e launa pū me kekahi me kekahi, e alakaʻi ana i kahi kūlana kiʻekiʻe e holo ai.

Molcular kaumaha o hpmc:ʻO ka viscosity o nā hopena hpmc e hoʻoponopono ikaikaʻia me ke kaumaha o ka polymer. ʻOi aku ka nui o nā makana molecular kiʻekiʻe e hana i nā hopena viscous hou aku. ʻO kēia no ka meaʻoi aku ka nui o nā moloki poʻokela poʻokela ma mua o ke kū'ēʻoi aku ka nui o kā lākou kaheʻana ma muli o kā lākou hoʻonuiʻana i ka hoʻonuiʻana a me kā lākou hoʻonuiʻana i ka hoʻonuiʻana.

Keka ao: Hoʻonui pinepineʻiaʻo Viscosity e like me ka hoʻonuiʻana o ka wela. ʻO kēia no ka meaʻoi aku ka hopena kiʻekiʻe loa i ka hōʻemi o nā mea i waena o nā poʻe HPMC ma waena o nā Molmc Molecules, no laila e hōʻemi i ko lākou hikiʻana i ka kahe.

Shore:ʻO ka Viscosity o HPMC e kū ana i ka helu helu HPMC Ma nā kumukūʻai haʻahaʻa haʻahaʻa,ʻo HPMC EXPICBIB,ʻoiai ma ke kiʻekiʻe kiʻekiʻeʻo Sher Sear

Ka hopena o ka ikaika oniic: Ke alo o nā electrolytes (e like me nā paʻakai) i ka hopena ke hoʻololi i ka viscosity. Hiki i kekahi mau Salts ke pale i nā pūʻali koa i waena o nā kaulahao ma waena o nā kaulahao polommer

3. Viscosity Viscosity Visceation: Nā nānā loiloi

Ua nānāʻia kahi hōʻailona maʻamau ma nā hoʻokolohuaʻo ia ka viscosity o nā reccosity o nā hopena hpmc aqueous Hiki ke weheweheʻia ka pilina ma waena o ka viscosity a me ka loaʻaʻana o ka hoʻohālikelikeʻana ma hope, e hoʻohana pinepineʻia no nā hoʻoponopono polyommer:

η = ACN \ ETA = AC ^ ND = ACN

Hea:

η \ ka etaka ka viscosity

Ccc ka mea e hoʻopili ai i ka hpmc

Aaa a me NNN no nā mea hoʻokūkū empirical empirical e hilinaʻi ana i keʻano kiko'ī o HPMC a me nā kūlana o ka hopena.

No nā mea haʻahaʻa haʻahaʻa,ʻo ka laina ka pilina, akā e like me ka piʻiʻana o kaʻike, e kū ana ka viscosity i ka nui o nā kaulahao ma waena o nā kaulahao ma waena

4. Viscosity Viscosity vs Molecular kaumaha

ʻO ke kaumaha molecular o Kimaclull®hpmc e pāʻani ana i kahi hana koʻikoʻi ma konaʻano viscosity. ʻOi aku ka nui o nā mea he nui molecular kiʻekiʻe e hana i nā hopena viscous hou aku i nā loli haʻahaʻa ma lalo o nā helu molena haʻahaʻa. ʻO ka viscosity o nā hoʻonā i hanaʻia mai nā molmc kiʻekiʻe-molmc e hiki ke kiʻekiʻe i nā kauoha he nui ma mua o nā hopena o ka hopena

No ka manawa, kahi hopena o ka HPMC me kahi paona molena o 100,000 da e hōʻike i kahi kiʻekiʻe o ka chancosity ma mua o 50,000 da ma keʻano likeʻole.

5. Hopena ma keʻano ma keʻano he viscosity

He hopena koʻikoʻi nui ka mahana ma ka viscosity o nā hopena HPMC. ʻO ka hoʻonuiʻana i ka mahana i alakaʻi i kahi hōʻemi i ka viscosity o ka hopena. ʻO kēia ka mea nui ma muli o ke neʻeʻana o ka kaulahao o nā kaulahao Pilommer ʻO ka hopena o ka mahana ma ka viscosity i helu pinepineʻia e hoʻohanaʻia me ka hoʻohanaʻana i kahi hoʻohālikelike o keʻano:

η (t) = η xa (t) = \ eta_0 e ^ {}

Hea:

η (t) \ eta (t) η (t) ka viscosity i ka mahana

η0 \ ETA_0η

Ee_eaa ka ikehu hana

Rrr ka mea mau

Tt ka wela loa

6. ʻO keʻano Rheological

ʻO ka rheology o nā hopena hpmc aqueous pinepineʻia e wehewehe pinepineʻia e like me new-newtonian Ma nā kumukūʻai haʻahaʻa haʻahaʻa, nā mea hoʻoponopono HPMC e hōʻike ana i kahi viscosity kiʻekiʻe ma muli o keʻano o nā kaulahao plyomer. Eia nō naʻe, e like me ka piʻiʻana o ka heluʻana, e emi ana ka viscoity-a he phenonson iʻikeʻia e like me kaʻehaʻana.

ʻO kēiaʻanoʻanoʻanoʻano maʻamau he maʻamau o nā hopena polymos he nui, me ka hpmc. Hiki ke weheweheʻia ka nui o ka hōʻikeʻana o ka viscosity i ka viscosity i ka hoʻohanaʻana i ke kumu hoʻohālike mana-kānāwai.

η (γ˙) = Kγ˙n-1 \ EAT {-gamma}) = K-˙ ˙

Hea:

γ˙ \ dot {-gamma] γ˙ ka pae o ka pā

ʻO KKK ka kuhikuhi kiko'ī

ʻO NNN keʻano o ka neʻeʻana o ke kahe (me N <1n <1n <1

7. ʻO ke kipaʻana o nā results HPMC:ʻO ka papaʻaina

Aia ma lalo nei he papa e hōʻuluʻulu i nā hiʻohiʻona viscosity o nā hopena o HPMC ma lalo o nā kūlana likeʻole:

ʻO nā hiʻohiʻona Viscosity oHpmcHoʻohanaʻia nā pilikia entious e kekahi mau mea, me ka neʻeʻana, e like me ke kaupaonaʻana; ʻO ka HPMC kahi mea nui loa, a me kāna mau waiwai waiwai e hiki ke hoʻopaʻaʻia no nā noi kiko'ī ma o ka hoʻoponoponoʻana i kēia mau'āpana. ʻO ka hoʻomaopopoʻana i kēia mau mea e hiki ai i ka hoʻohana ponoʻana o ka umacell®hpmc i nāʻoihana likeʻole, mai nā lāʻau lapaʻau a me nā mea kanu lāʻau. Ma ke kuhikuhiʻana i nā kūlana ma lalo o ka HPMC, hiki i nā mea hana ke hoʻokō i nā waiwai i makemakeʻia e loaʻa i nā waiwai i makemakeʻia no ko lākou mau waiwai.
