Hydrexypropropsl hydrolcellse (HPMC)aMathylcellse (mc)aia nā meaʻelua celilouse maʻamau i hoʻohana pinepineʻia ma nāʻanoʻoihana, e komo pū me nā mea lapaʻau, meaʻai, a me ka hanaʻana. ʻOiai ko lākou mau mea like, ua loaʻa kēia mau meaʻelua i nā waiwai a me nā noi.
1. Kahua kūlohelohe
ʻO ka HPMCʻelua a me MC he cellulose derivatives, akā e waiho ana ka mea likeʻole i nā hui e pili ana i nā hui celctical i hoʻopiliʻia i ke kua.
Mathylcellse (mc): Ua hoʻokumuʻia kēia ma ka huiʻana o ka cellulose. Ma kēia kaʻina hana, hui huiʻo Anthsl (-Can3) i nā hui hydroxyl o nā molluluse. Hoʻololi maʻamau ka pae mitylation ma waena o 20-30%, e pili ana i ka papa o MC, kahi i hoʻohālikelike ai i kāna mau palena a me nā waiwai'ē aʻe.
Hydrexypropropsl hydrolcellse (HPMC): Ua loaʻa iā Kimacell®hpmc i kahi mea paʻakikī loa. Ma kahi o ka mithylation, e hele pū ana me ka hydroxybopyplay. Nā hui Hydroxyproopsl (-ch2chohhch3) Hiki i ke kiʻekiʻe o ka hydroxyprocklation a me ka pae kiʻekiʻe o ka hpmc hiki ke loli nui, e ala i nāʻano o nā hua hpmc me nāʻano likeʻole.

2. Kū kū
ʻO ka pānaʻi kekahi o nā mea nui loa i ka hoʻohālikelikeʻana i ka MC a me HPMC. Ke hilinaʻi nei ka hopena o kēia mau cediterat celilose ma luna o ke kihi o ke kumu a me keʻano kiko'ī o ka waihona.
Mathylcellse (mc): E hoʻomoʻaʻiaʻo mc i ka wai wela akā e hana i kahi gel ma ka hōʻoluʻolu. ʻO kēia waiwai kūʻokoʻa o ka hanaʻana i nā gels i ka wā i hoʻomehanaʻia a me nā pale i kahi kūlana wai ma keʻano he nui o nāʻano nui o ka mc. He insoluble i loko o ka wai anuanu, akā hoʻoluʻu i ka wai wela ma luna o kekahi mau pae kiʻekiʻe ma luna o kekahiʻano wela (50-70 ° C)
Hydrexypropropsl hydrolcellse (HPMC): HPMC, ma kaʻaoʻao'ē aʻe, e lūlū i loko o ka wai anuanu a me ka wai wela. ʻO kēia ka mea e hoʻohālikelike ai i ka voretinile i hoʻohālikelikeʻia i mc. Ua hoʻohālikelikeʻia ka pālolo o HPMC e keʻano o keʻano (ʻo ka pae o ka mitdroxypopyl i nā pūʻulu hydroxyproopyl) a me ka papa viscosityprockl ʻOi aku ka kiʻekiʻe o nā kiʻekiʻe kiʻekiʻe e hana i ka hpmc hou aku i ka wai ma ka wai ma nā haʻahaʻa haʻahaʻa.

3. Viscosity
Ke pāʻani neiʻo Viscosity i kahi hana koʻikoʻi i nā noi he nui
Mathylcellse (mc):ʻO ka Viscosity o nā wikiō Kimacell®mc Ka piʻiʻana o ka viscolisity i ka wā i hoʻomehanaʻia, a ke hōʻike neiʻo ia i ka phenomenon o ka getion. ʻO ke kiʻekiʻe o ka scashment e pili ana i ka viscosity i ka viscosity, me nā kiʻekiʻe kiʻekiʻe o ke kiʻekiʻe e pili ana i ke kiʻekiʻe o ka viscosity kiʻekiʻe.
Hydrexypropropsl hydrolcellse (HPMC): Hpmc maʻamau he nui loa i hoʻohālikelikeʻia i keʻano viscosity i hoʻohālikelikeʻia i ka MC. ʻO ka mākaʻikaʻi o ka HPMC i hoʻohālikelikeʻia e ka pae o ke kumukānāwai, akā e noho mau anaʻo ia ma waena o kahi pālahalaha nui. Eia kekahi, hiki ke heleʻiaʻo HPMC i nā mea'ē aʻe e loaʻa i nā hōʻailona likeʻole, mai ka haʻahaʻa, e pili ana i ka noi i manaʻoʻia.

4. Noi
Hoʻohana pinepineʻiaʻo MC a me HPMC i ka holomua o ka hale kūʻai, nā meaʻai, a me nāʻano waiwaiʻo kēlā me kēia e kūpono i nā noi.
Mathylcellse (mc):
Nā hale hakakala: Hoʻohana pinepineʻiaʻo MC ma keʻano he mea paʻa, ka mea hana, a me ka mea hoʻohana i ke kāʻei ma nā papa hana ma muli o kāna mau helu helu. Hoʻohanaʻia ia i nāʻano hana i hoʻopaʻaʻia.
ʻOihana Hōʻea: Ua hoʻohanaʻiaʻo MC i kahi meaʻai meaʻaiʻai, emulifier, a me ka stabilizer. He waiwai nui nā waiwai o ka huiʻana i nā huahana e like me ka aila aila, nā huahana kālepa.
Nā'āpono: Hoʻohanaʻiaʻo mc i nā mea kanu i kona mau sosmetics no kāna sissicky
Hydrexypropropsl hydrolcellse (HPMC):
Nā hale hakakala: Ua hoʻohana nuiʻiaʻo HPMC e like me kahi mea paʻa a me nā mea hoʻokele e hoʻokele ai i ka papa hana i nā papa papa. Ua hoʻohanaʻia nō hoʻi ma Ophthalmic Solutions e like me ka lubricant a i nā'ōnaehana hana e pili ana i nā lāʻau lapaʻau.
ʻOihana Hōʻea: Ua hoʻohanaʻiaʻo HPMC ma Gluten-Free Breking, e like me keʻano o kaʻatikala a me ka elasticity o glutun i ka palaoa. Ua hoʻohanaʻia ia ma keʻano he stabilizer a emulsifier i nā meaʻai i hanaʻia.
Kūkulu hoʻi: HPMC i hoʻohanaʻia e like me ka hoʻohui o ka com indity, plate, a me nā lāʻau a me nā lua. Ua hoʻomaikaʻiʻo ia i ka hana hana, e kū ana ka wai, a me ka amemesion.

5. Nā waiwai'ē aʻe
ʻO ka hygroscopity: Hpmc maʻamau he nui hygroscopic (ka wai-wai-wai-ma mua o mc, e pono ai e hana i nā noi.
Kūlohelohe: MC i hōʻikeʻia e hōʻike i ka paʻakikīʻoi aku ka maikaʻi ma muli o kona waiwai nui. Hpmc,ʻoiai ke kūpaʻa i loko o kahi kūlana wela,ʻaʻole paha e hāʻawi i ka hopena o keʻano o keʻano o keʻano like me keʻano
