Hydroxypropyl methylcellulose (HPMC)he polymer versatile i hoʻohana ʻia i nā ʻoihana e like me ka lāʻau lapaʻau, ke kūkulu ʻana, nā mea hoʻonaninani, nā meaʻai, a me ka mālama pilikino. He kuleana koʻikoʻi ka viscosity o HPMC i ka hoʻoholo ʻana i kona kūpono no nā noi like ʻole. Hoʻopili ʻia ka viscosity e ka paona molekala, degere o ka hoʻololi ʻana, a me ka ʻike. Pono ka hoʻomaopopo ʻana i nā māka viscosity kūpono no ke koho ʻana i ka HPMC kūpono no nā pono ʻoihana kikoʻī.
Ana Viscosity
Ana maʻamau ka viscosity o AnxinCel®HPMC i loko o nā ʻoluʻolu wai me ka hoʻohana ʻana i ka viscometer rotational a capillary paha. ʻO ka mahana ho'āʻo maʻamau he 20 ° C, a ua hōʻikeʻia ka viscosity i millipascal-kekona (mPa·s a i ʻole cP, centipoise). Loaʻa nā viscosities like ʻole o ka HPMC ma muli o kā lākou noi i manaʻo ʻia.
Nā Papa Viscosity a me kā lākou mau noi
Hōʻike ka papa ma lalo nei i nā māka viscosity maʻamau o HPMC a me kā lākou mau noi pili.

Nā mea e pili ana i ka viscosity
ʻO kekahi mau mea e pili ana i ka viscosity o HPMC:
Kaumaha Molekala:ʻO ke kaumaha molekala kiʻekiʻe ke alakaʻi i ka hoʻonui ʻana i ka viscosity.
Degree of Substitution:ʻO ka ratio o nā hui hydroxypropyl a me methyl e pili ana i ka solubility a me ka viscosity.
ʻO ka hoʻonā ʻana:ʻOi aku ka nui o ka ʻike i ka viscosity.
Mahana:Ke emi nei ka viscosity me ka piʻi ʻana o ka mahana.
ʻIke pH:Paʻa nā haʻina HPMC i loko o ka pae pH o 3-11 akā hiki ke hoʻohaʻahaʻa ma waho o kēia pae.
Laki ʻāhi:Hōʻike ka HPMC i nā waiwai kahe non-Newtonian, ʻo ia hoʻi, e emi ana ka viscosity ma lalo o ke koʻikoʻi shear.
Noʻonoʻo Noʻonoʻo
ʻO nā lāʻau lapaʻau:Hoʻohana ʻia ʻo HPMC i nā ʻano lāʻau lapaʻau no ka hoʻokuʻu ʻia ʻana a ma ke ʻano he mea hoʻopaʻa i nā papa. ʻO nā māka viscosity haʻahaʻa (100–400 mPa·s) i makemake ʻia no ka uhi ʻana, aʻo nā māka kiʻekiʻe (15,000+ mPa·s) e hoʻohana ʻia no ka hoʻopuka hoʻokuʻu mau.
Kūkulu ʻia:Hana ʻo AnxinCel®HPMC ma ke ʻano he mea hoʻopaʻa wai a hoʻopili i nā huahana sima. He kūpono nā māka kiʻekiʻe-viscosity (ma luna o 4,000 mPa·s) no ka hoʻomaikaʻi ʻana i ka hana a me ka ikaika paʻa.
Nā mea hoʻonani a me ka mālama pilikino:I nā shampoos, lotions, a me nā ʻaila, hana ʻo HPMC ma ke ʻano he mānoanoa a me ka stabilizer. Hāʻawi nā māka viscosity liʻiliʻi (400–1,500 mPa·s) i kahi kaulike maikaʻi loa ma waena o ke ʻano a me nā waiwai kahe.
ʻOihana meaʻai:Ma ke ʻano he mea hoʻohui meaʻai (E464), hoʻomaikaʻi ʻo HPMC i ke ʻano, kūpaʻa, a me ka paʻa ʻana o ka wai. ʻO nā māka viscosity haʻahaʻa (5–100 mPa·s) e hōʻoia i ka hoʻopuehu kūpono me ka ʻole o ka mānoanoa nui.
ʻO ke koho ʻana oHPMCʻO ka pae viscosity e pili ana i ka noi i manaʻo ʻia, me nā māka viscosity haʻahaʻa kūpono no nā haʻina e koi ana i ka mānoanoa liʻiliʻi a me nā māka viscosity kiʻekiʻe i hoʻohana ʻia i nā mea hoʻohālikelike e koi ai i nā waiwai paʻa a paʻa. ʻO ka mana viscosity kūpono e hōʻoia i ka hana maikaʻi i nā lāʻau lapaʻau, kūkulu, meaʻai, a me nā ʻoihana hoʻonaninani. ʻO ka hoʻomaopopo ʻana i nā mea e hoʻopiʻi ai i ka viscosity e kōkua i ka hoʻohana ʻana i ka HPMC no nā noi ʻoihana like ʻole.
