Ua manaʻo ʻia ʻo HPMC 200000 viscosity he viscosity kiʻekiʻe?

ʻAe, ʻo Hydroxypropyl Methylcellulose (HPMC) me ka viscosity o 200,000 mPa·s (millipascal-seconds) i manaʻo nui ʻia he viscosity kiʻekiʻe. ʻO ka viscosity kahi ana o ke kūʻē ʻana o ka wai i ke kahe ʻana, a ʻo HPMC me ka viscosity o 200,000 mPa·s e loaʻa i kahi kūpaʻa kiʻekiʻe ke kahe e hoʻohālikelike ʻia me nā māka haʻahaʻa viscosity.

Loaʻa ka HPMC ma kahi ākea o nā māka viscosity, maʻamau mai 5,000 mPa·s a i 200,000 mPa·s a ʻoi aku paha. ʻO ka māka viscosity kikoʻī e koi ʻia no kahi noi kikoʻī e pili ana i nā mea e like me nā waiwai rheological i makemake ʻia, ke ʻano noi, nā kūlana substrate, a me nā koi hana.

Ma keʻano laulā, hoʻohana pinepine ʻia nā māka viscosity kiʻekiʻe o ka HPMC i nā noi kahi e makemake ʻia ai kahi paʻa ʻoi aku ka mānoanoa a i ʻole ka paʻa ʻana o ka wai, e like me nā mea mānoanoa, nā uhi, nā adhesives, a me nā huahana sima. Hāʻawi kēia mau māka kiʻekiʻe-viscosity i ke kūpaʻa sag ʻoi aku ka maikaʻi, hoʻomaikaʻi i ka hana, a me ka hoʻonui ʻana i ka hana ma nā noi kū a i ʻole ma luna.

Pono e hoʻomaopopo ʻia ʻaʻole hiki i ka viscosity wale nō ke hoʻoholo piha i ke kūpono o ka HPMC no kahi noi kikoʻī, a ʻo nā mea ʻē aʻe e like me ka puʻunaue ʻana i ka nui o nā ʻāpana, ka maʻemaʻe, a me nā waiwai kemika. Pono e noʻonoʻo i nā mea pili āpau a e nīnau i nā kikoʻī o ka huahana a me nā pepa ʻikepili ʻenehana i ke koho ʻana i ka māka viscosity kūpono o HPMC no kahi hoʻonohonoho a i ʻole noi.
