ʻO HPMC Polymer Viscosity ma keʻano he hana o ka mahana

ʻO HPMC (hydroxyproopyl milllcelllose) he polymer maʻamau maʻamau i hoʻohanaʻia i loko o ka lāʻau lapaʻau, ka meaʻai a me nā hana maʻamau a me nāʻoihana maʻamau. He cellulose derivative i hanaʻia e ka chemika e hoʻololi ana i ka cellulose kūlohelohe maoli. ʻO kekahi o nā mea nui o ka HPMC,ʻo ia kona viscosity

ʻO Viscosity kahi ana o kahi wai a iʻole ke kū'ēʻana i keʻano o keʻano. No ka mea hana HPMC,ʻo Viscosity kahi mea nui e pili ana i ka hanaʻana i ka hana o nā mea ma nā noi likeʻole. ʻO ka Viscosity o HPMC e pili ana i kekahi mau mea e like me ke kaumaha molela

ʻO ka pilina o ka mahana o ka mahana o ka poʻe HPMC

Hōʻikeʻo HPMC polymers i kahi pilina nonlinear ma waena o ka viscosity a me ke wela. Ka'ōlelo maʻamau, e hoʻonui ana i ka hoʻonui i ka mahana e hōʻemi ai i kahi haʻahaʻa ma ka viscosity. Hiki ke weheweheʻia kēiaʻano hana e:

1. E pili ana ka mahana i ka boddrogen bond

I nā polymc polymers, nā keleponaʻo Intermolecular Hydrogen Kōkua kēia'ōnaehana pūnaewele e hoʻonui i ka viscosity o nā mea. Hoʻonui ka hoʻonui nuiʻana i nā kīʻaha hydrogen e wāwahi, ma laila e hōʻemi ana i nā mea hoihoi i waena a no laila e hōʻemi i ka viscosity. Me keʻano, he hoʻemi i ka mahana e pili ana i nā bond-hydrogen i nā paʻa hydrogen e hana ai, e hopena ana i ka piʻiʻana o ka viscosity.

2. E pili ana ka mahana i ka neʻe molecular

I nā kiʻekiʻe kiʻekiʻe,ʻoi aku nā molena i loko o nā kaulahao o HPMC a hiki i ka ikaika kinetic kiʻekiʻe a hiki ke neʻe hou aku. Ua hoʻonuiʻia kēia neʻe molecular e hoʻonui i keʻano o ka hoʻolālāʻana a me ka hoʻemiʻana i kona viscosity.

ʻO ka Viscosity o HPMC POLLEMCONS e hilinaʻi nei i keʻano o keʻano. ʻO kekahi mau mea hana, e like me ka wai, hōʻike i kahi hōʻemi ma ka viscosity ma muli o ka hoʻonuiʻana o ka hydrogen ma muli o ka nāwaliwaliʻana I ka hoʻohālikelikeʻana, ua hoʻonuiʻia kekahi mau kala i ka viscosity ma nā kiʻekiʻe kiʻekiʻe, e like me ka glycetrol.

He mea kūpono ia e hoʻomaopopo ana i nā kiko'ī o ka pilina o ka mahana-viscosity no ka hpmc e hilinaʻiʻia ma ka papa kuhikuhi ʻO ka hōʻike, ua hōʻikeʻia nā uku HPMC i nā hauoli me ka piʻi ikaikaʻana,ʻoiaiʻoi aku ka paʻa o kekahi. Eia hoʻi nō, ka nui o ka nānāʻana o ka hpamc e hoʻonui ana i ka nui o ka hoʻomakeʻia, a me ka pilina ma waena o ka mana a me ka heʻe.

Ka mea nui o ka viscosity i nā noi hpmc

Ma kaʻoihana lāʻau lapaʻau,ʻo HPMC kahi mea maʻamau maʻamau i hoʻohanaʻia ma nā'ōnaehanaʻoihana, kahi e pono ai ka mana o ka hana o ka lāʻau a me keʻano kūpono. Hoʻopiliʻo Viscosity i kahi hana koʻikoʻi ma keʻano o ka hanaʻana i ka manawa e pili ana i ka hoʻopilikiaʻana i ka lāʻau lapaʻau ma o ka polymer matrix. Eia kekahi, he mea nui ka viscosity o HPMC i nāʻano papaʻaina, e like me ka mea kiʻekiʻe e pono ai e hōʻoia i ka lole lole.

ʻO nā huahana meaʻai e hoʻohana ai i ka HPMC e like me keʻano o ka mea kūʻai aku a me ka Emulsifier i nā waiwai Viscosier kūikawā e hōʻoia i ka hoʻomau a me ka hanaʻana. Pela hoi, e hoʻohana pono ai nā bipi pule, e hoʻohanaʻia ana ka mea i like me ka poʻe e makemake ai ka nupus.

ʻO HPMC kahi polymer nui loa e hōʻike ana i kahi pilina nonlinear ma waena o ka viscosity ma waena o ka viscosity a me ka wela. Hoʻonuiʻia ka hopena o ka wela ma ka emiʻana o ka viscosity,ʻoi aku ka nui o ka hopena o ka mahana, nā waiwai molele. Hiki i ka hoʻomaopopoʻana i keʻano o ka mahana o ka marcosity o ka poscosity o hpmc hiki ke kōkua i nā huahana me nā mea i makemakeʻia a makemakeʻia. No laila,ʻo ke aʻoʻana o HPMC VISCOSIty he mea nui e hōʻoia i ka hana maikaʻi loa i nā noi likeʻole i nā noi likeʻole.
