Hydroxypropyl methylcellulose (HPMC) he cellulose ether non-ionic i hoʻohana nui ʻia i ke kūkulu ʻana, ka lāʻau lapaʻau, ka meaʻai, nā mea hoʻonaninani a me nā ʻoihana kemika. ʻO nā hiʻohiʻona viscosity o kāna solution aqueous nā kumu nui e pili ana i kāna hana noi.
1. Nā hiʻohiʻona kumu o HPMC
ʻO AnxinCel®HPMC kahi mea hoʻoheheʻe cellulose i hoʻohui ʻia e ka hoʻokomo ʻana i nā pūʻulu hydroxypropyl a me methyl i loko o ke kaulahao molecular cellulose. Loaʻa iā ia ka hoʻoheheʻe wai maikaʻi a me ka viscosity kiʻekiʻe, a hoʻohana pinepine ʻia e hoʻomākaukau i nā hoʻonā wai me nā waiwai rheological kikoʻī. Hoʻohana nui ʻia kēia mau hiʻohiʻona i ka HPMC i nā uhi, nā adhesives, ka hoʻokuʻu ʻana i ka lāʻau lapaʻau, nā meaʻai a me nā ʻoihana ʻē aʻe.
2. ʻO nā hiʻohiʻona viscosity o HPMC aqueous solution
Hoʻopili ʻia nā hiʻohiʻona viscosity o ka HPMC aqueous solution e nā kumu he nui, ʻo ia hoʻi me ka neʻe ʻana, ka mahana, ka nui o ka shear, ka waiwai pH a me ke ʻano mole.
Ka hopena o ka manaʻo ma luna o ka viscosity
Hoʻonui ka viscosity o HPMC aqueous solution me ka hoʻonui ʻana i ka ʻike. Ke haʻahaʻa ka ʻike o ka HPMC, ʻeleʻele ka wai a me ka viscosity haʻahaʻa; i ka piʻi ʻana o ka manaʻo, piʻi ka pilina ma waena o nā molekala, a piʻi nui ka viscosity o ka wai. ʻO ka mea maʻamau, pili nui ka viscosity o ka solution HPMC i kona hoʻopaʻa ʻana, akā ʻoi aku ka paʻa ma kekahi ʻano hoʻohālikelike, e hōʻike ana i nā ʻano viscosity o ka hopena.
Ka hopena o ka wela ma ka viscosity
He mea koʻikoʻi ka mahana e pili ana i ka viscosity o AnxinCel®HPMC aqueous solution. Ke piʻi aʻe ka mahana, e nāwaliwali nā paʻa hydrogen a me nā pilina hydrophobic i loko o nā molekala HPMC, e hopena i ka emi ʻana o ka ikaika paʻa ma waena o nā molekala, a laila e hōʻemi ana i ka viscosity o ka wai. ʻO ka ʻōlelo maʻamau, ʻo ka viscosity o ka HPMC aqueous solution e hōʻike ana i kahi hiʻohiʻona nui i lalo me ka piʻi ʻana o ka mahana, ʻoi aku ka nui o ka pae wela. ʻO kēia hiʻohiʻona ka HPMC i ʻoi aku ka maikaʻi o ka hoʻoponopono ʻana i kekahi mau noi hoʻomalu wela.
Ka hopena o ka shear rate ma ka viscosity
Hōʻike ka hoʻonā wai wai HPMC i nā ʻano wai Newtonian maʻamau i nā haʻahaʻa ʻoki haʻahaʻa, ʻo ia hoʻi, paʻa ka viscosity; akā naʻe, ma ke kiʻekiʻe o ka ʻāʻili ʻana, e emi nui ka viscosity o ka solution HPMC, e hōʻike ana he waiwai ʻāwili kona. Loaʻa i nā molekala HPMC kekahi mau waiwai rheological. Ma nā haʻahaʻa haʻahaʻa haʻahaʻa, ʻoi aku ka wili o nā kaulahao molekala, e hana ana i kahi kūpaʻa kiʻekiʻe kiʻekiʻe, i hōʻike ʻia ma ke ʻano he viscosity kiʻekiʻe; i nā kiʻekiʻe o ka ʻāwīwī, hoʻopololei nā kaulahao molekala, hoʻonui ʻia ka wai, a emi ka viscosity.
Ka hopena o ka waiwai pH ma ka viscosity
Mālama ʻia ka wai wai HPMC i kahi viscosity paʻa ma lalo o nā kūlana alkaline palupalu a nāwaliwali. I loko o kahi ʻakika ikaika a i ʻole ka pae kumu ikaika, hiki i nā molekala HPMC ke hana i ka protonation a i ʻole deprotonation reactions, ka hopena i nā loli i ka hydrophilicity, hydrophobicity a me nā pilina intermolecular ma waena o nā molekala, a laila e hoʻopili ai i ka viscosity o ka wai. Ma lalo o nā kūlana maʻamau, liʻiliʻi ka hopena o ka hoʻololi ʻana i ka pH i ka viscosity o nā haʻina HPMC, akā ma lalo o nā kūlana pH koʻikoʻi, ʻike ʻia ka loli viscosity.
Ka hopena o ka molekalale i ka viscosity
ʻO nā hiʻohiʻona viscosity o HPMC pili pili i kona ʻano mole. ʻO ke kiʻekiʻe o ka hoʻololi ʻana o nā pūʻulu hydroxypropyl a me methyl i loko o ka mole he hopena koʻikoʻi i ka viscosity o ka hoʻonā wai. ʻOi aku ka kiʻekiʻe o ka hoʻololi ʻana o ka hui, ʻoi aku ka ikaika o ka hydrophilicity o HPMC a ʻoi aku ka kiʻekiʻe o ka viscosity o ka hopena. Eia kekahi, ʻo ka paona molekala o HPMC kekahi kumu nui e pili ana i kona viscosity. ʻOi aku ka nui o ke kaumaha o ka molekala, ʻoi aku ka lōʻihi o ke kaulahao mole, a ʻoi aku ka ikaika o ka pilina ma waena o nā molekala, e hopena i ka viscosity kiʻekiʻe o ka hoʻonā wai.
3. ʻO ke koʻikoʻi o nā hiʻohiʻona viscosity o HPMC aqueous solution i ka noi
ʻO nā hiʻohiʻona viscosity o ka HPMC aqueous solution he mea koʻikoʻi i kāna hoʻohana ʻana ma nā ʻano āpau.
Ke kahua kūkulu: Hoʻohana pinepine ʻia ʻo HPMC i ka mortar sima a me nā adhesives, a loaʻa iā ia nā hana o ka mānoanoa, mālama ʻana i ka wai, a me ka hoʻomaikaʻi ʻana i ka hana hana. Hoʻopili pololei kāna mau hiʻohiʻona viscosity i ka hana a me ka pili ʻana o ka mortar. Ma ka hoʻoponopono ʻana i ka ʻike a me ka molecular structure o HPMC, hiki ke mālama ʻia nā waiwai rheological o ka mortar, a laila e hoʻomaikaʻi ai i ka maʻalahi o ke kūkulu ʻana.
ʻOihana lāʻau lapaʻau: Hoʻohana pinepine ʻia ka wai wai AnxinCel®HPMC i ka hoʻomākaukau ʻana e like me nā lāʻau lapaʻau hoʻokuʻu ʻia, nā pūpū capsule, a me nā kulu maka. Hiki i kāna mau hiʻohiʻona viscosity ke hoʻopili i ka hoʻokuʻu ʻana o nā lāʻau lapaʻau a hoʻomalu i ke kaʻina hoʻokuʻu o nā lāʻau i loko o ke kino. Ma ke koho ʻana i ka HPMC me ke kaumaha molekala kūpono a me ke kiʻekiʻe o ka hoʻololi ʻana, hiki ke hoʻoponopono ʻia nā hiʻohiʻona hoʻokuʻu o nā lāʻau no ka loaʻa ʻana o nā hopena therapeutic pololei.
ʻOihana meaʻai: Hoʻohana ʻia ʻo HPMC ma ke ʻano he mānoanoa, stabilizer, a me ka emulsifier i ka hana ʻai. Hoʻopili nā hiʻohiʻona viscosity o kāna ʻano wai i ka ʻono a me ka paʻa o ka meaʻai. Ma ka hoʻololi ʻana i ke ʻano a me ka nui o ka HPMC i hoʻohana ʻia, hiki ke hoʻomalu pono ʻia ke ʻano o ka meaʻai.
ʻOihana Hoʻomaʻamaʻa: HPMC, ma ke ʻano he mānoanoa a me ka stabilizer i nā mea hoʻonaninani, hiki ke hoʻomaikaʻi i ke ʻano o ka huahana, hāʻawi iā ia i ka wai kūpono a me ka manaʻo maikaʻi. He hopena koʻikoʻi kona ʻano viscosity i ka ʻike mea hoʻohana o nā huahana e like me ka creams, gels, a me shampoos.
ʻO nā hiʻohiʻona viscosity oHPMC Hoʻopili ʻia nā ʻōhua wai e nā mea he nui e like me ka neʻe ʻana, ka mahana, ka nui o ka shear, ka waiwai pH, a me ke ʻano molekala. Ma ka hoʻoponopono ʻana i kēia mau mea, hiki ke hoʻokō ʻia ka hana noi o HPMC e hoʻokō i nā pono o nā ʻoihana like ʻole no kāna mau waiwai rheological. ʻO ka noiʻi hohonu e pili ana i nā hiʻohiʻona viscosity o ka HPMC aqueous solutions ʻaʻole kōkua wale i ka hoʻomaopopo ʻana i kāna mau waiwai kumu, akā hāʻawi pū kekahi i ke alakaʻi theoretical no kāna noi i ka hana maoli.
