ʻO keʻano o keʻano o ka hopena o HPMC
Ma ka laulā,ʻo ke kaumaha o kahi wai i hiki ke hōʻikeʻia ke kahe o ke kahe o ka soar i kahi manawa o ka senast o ka shar rate ƒ. E pili ana i keʻano o ƒ (γ), hiki ke hoʻokaʻawaleʻia nāʻano likeʻole:ʻO nā wai āpau
Ua hoʻokaʻawaleʻia nā keiki ma nā'āpana heʻelua No ka rheology o kēia mauʻano like o nā nalo cellouse. Sc naik et al. Hanaʻia i kahi haʻawina hoʻohālikelike a me keʻano hoʻohālikelike i ke aʻoʻana ma ka cellulose collulouse a me nā sodium carboxymyl cell. Ua hōʻike nā hopena i nā hopena non-Ionic cellouse ether nā hopena a me ka onic cellouse eter solituns he pseudoplastic. ʻO nā kahe,ʻo ia nā kahe non-Newtonian, e hoʻokokoke i nā wai hou i nā mea haʻahaʻa haʻahaʻa loa. ʻO ka pseudoplastictity o ka hydroxypopyll miyylcelulose sim e hoʻokani i kahi hana koʻikoʻi i ka noi. No ka laʻana, i ka wā e hoʻopiliʻia ai i nā lole, ma muli o keʻano heʻe o ka hopena o ka hopena . ^. Ua nui ka hopena; ʻOiai e hoʻomaha ana,ʻo ka viscosity o ka hopena e nui loa ka hopena,ʻo ia ka mea e mālama pono ai i ka waihoʻana o nā pākaha puaʻa i loko o ka papa o ka puaʻa puaʻa.

ʻO ka hōʻike hōʻike hōʻike HPMC Viscosity
ʻO kahi hōʻailona koʻikoʻi e ana i ka hopena o ka hopena o ka hydroxypopyl o hydroxlyl ʻO keʻano o ke anaʻana o ka viscosity iʻike pinepineʻia e pili ana i keʻano o ka corcosity ciscosity.
Aia:ʻo ia ka mea nānā iʻikeʻia, MPA s; K ka mea e pili ana i ka visomerheder; d is the density of the spect sample on 20/ 20 ° C; t ka manawa no ka hopena e hele ai ma kaʻaoʻao o keʻano o ka viscomerter i lalo ʻO ka manawa e holo ai keʻano o ke aila ma o ka viscomerter i keʻano.
Eia nō naʻe,ʻoi aku keʻano o ke anaʻana e ke anaʻana o ka corplary ciscomer. Nā mākaʻikaʻi o nā mea he nuiNā NaloʻoHe mea paʻakikī ke kiʻi i ka hoʻohanaʻana i kahi viscomer ma muli o ka mea i loaʻa i ka nui o nā mea iʻikeʻia i ka wā o ka callillary No laila,ʻo ka hapa nui o nā mea hana e hoʻohana i nā viscomers ciscomers e kāohi i ka maikaʻi o ka maikaʻi o hydroxyprololose. Ua hoʻohana pinepineʻia nā mea kipa o Brookfield ma nā'āina haole, aʻo nā Viscomerters NDJ e hoʻohanaʻia ma Kina.

Ka hoʻouluʻana i nā mea o ka HPMC Viscosity
3.1 pilina me ke kiʻekiʻe o ka hoʻohuiʻana
Ke loliʻoleʻia nā'āpana'ē aʻe, keʻano o ka viscosity o ka hopena hydrocypopyl minika Ua hōʻike houʻia kēia hopena ma ka hihia o ka pae haʻahaʻa o ka polyhization ma mua o ka hihia o ke kiʻekiʻe o ka polyhization kiʻekiʻe.
3.2 ka pilina ma waena o Viscosity a me ka noʻonoʻoʻana
ʻO ka nānāʻana o ka viscosity o ka hydroxyprooppoppyl methylcreellse e hoʻonui me ka hoʻonui o ka nui o ka huahana i ka hopena o ka huahana. ʻO kahi loli hoʻololi liʻiliʻi e lilo i ka loli nui i ka viscosity. Me ka viscosity nominal o ka hydroxyprooppyl middylsellse i ka hopena o ka loli o ka hoʻololiʻana o ka snoctory ma keʻano heʻoi aku kaʻike.
3.3 ka pilina ma waena o ka viscosity a me ka heluʻana
ʻO Hydroxyprooparplose athylcrelllous aqueous ka hopena o ka waiwai o ka hōʻailona. ʻO Hydroxyprooppyl Minukelse o nā viscosiLealse of New Likemin i hoʻomākaukauʻia i 2% mau hopena Aqueous, aʻo kona mau viscosity e ana i nā kumukūʻai likeʻole ma nāʻano likeʻole. ʻO nā hopena e like me ka hōʻikeʻana e like me ka hōʻikeʻana ma ke kiʻi. Ma ka haʻahaʻa haʻahaʻa haʻahaʻa,ʻaʻole i loli nui ka viscosity o hydroxyroplose uila. Me ka hoʻonuiʻana o ka helu hoʻoaliʻi,ʻo ka mea aʻo i ka maʻi hydroxyropyl mathylcell iʻoi aku ka hoʻomaʻamaʻa nuiʻana.
3.4 ka pilina ma waena o Viscosity a me keʻano
ʻO ka mākaʻikaʻi o ka vydroxypopyl miyylcelllory streem e hoʻopilikia nuiʻia e ka mahana. E hoʻonui ana keʻano o ka mahana,ʻo ka viscosity o ka hopena e emi ai ka hopena. E like me hōʻikeʻia i ke kiʻi, ua hoʻomākaukauʻia i kahi hoʻonā aqueous me ka neʻeʻana o 2%, a me ka loli o ka maka'āinana i pau.
3.5 i nā mea'ē aʻe'ē aʻe
ʻO ka nānāʻana o ka maʻi o ka hoʻonāʻana o ka hoʻonāʻana o ka hydroxxyprooparllose i piliʻia e ka hoʻohuiʻana i ka hoʻonā, a me nā'āpana moleʻole. ʻO ka maʻamau, i mea e loaʻa ai ka hanaʻoi aku ka maikaʻi a hōʻemi paha i ke kumukūʻai, pono e hoʻohui i nā clay a me ka clany clay. , ʻAʻole e pili wale kēia mau hoʻohui i nā waiwai o nā viscosity o nā mea e pono ai keʻano o ka mea e pili ana i nā waiwai o hydrocelsel. , sag pale pale, etc.
ʻO ka viscosity o ka hopena o keʻano o ka maʻi o ka hydroxyproopyl methylcrelllose e pili ana iā Actid a me Alkali, aʻo ia hoʻi kahi Actich Actib , bortic acid, citric acid, etc.) Akā, e hōʻemi anaʻo ka acid acid acid e hōʻemi i ka viscosity. Akāʻo Sustic Soda, Potassaum hydroxide, lime wai, etc. loaʻa ka hopena liʻiliʻi ma luna. Hoʻohālikelikeʻia me nā makuahine'ē aʻe,hydrexxypopypoprowlseʻO ka hopena Aquous maikaʻi loa i ka hana antimicrobial Ma ka debeation o ka molouluse etherd molele a me nā chim sciss. ʻO ka hana ka mea iʻikeʻia ai keʻano o keʻano o ka hoʻonāʻana o ka pono o ka lāʻau. Inā pono e mālama i ka hoʻonā o ka aqueous o ka hydroxxyprooparllulose i ka manawa lōʻihi,ʻaʻole i koiʻia ka nui o ka trace o keʻano he nui. Ke kohoʻana i nāʻoihana anti-fungal, Preservatives a iʻole nā Fungicides a me nā huahana'ē aʻe. hiki ke pāʻani i kahi hana kūpono.
