He aha ke ano viscosity o ka solution aqueous hydroxypropyl methyl cellulose?
He ākea ākea ka Hydroxypropyl methyl cellulose i ka ʻoihana kūkulu, a ʻo kāna mau mānoanoa maikaʻi loa a me nā waiwai paʻa wai e hoʻohana ʻole ʻia i kāna noi i ka ʻoihana kūkulu.Akā, pehea ka nui o kā mākou ʻike e pili ana i kona maikaʻi?I kēia manawa, e kamaʻilio e pili ana i nā waiwai viscosity o ka solution aqueous hydroxypropyl methyl cellulose.
Hydroxypropyl methyl cellulose aqueous solution hoʻolauna maʻalahi: English abbreviation HPMC non-ionic, wai-soluble cellulose ether, ke ʻano o ke keʻokeʻo a i ʻole ka pauka melemele māmā a i ʻole nā mea granular.ʻO kona ʻono ʻole, ʻala ʻole, ʻona ʻole, nā waiwai kemika paʻa o ka huahana i loko o ka wai e hana i kahi wai liʻiliʻi liʻiliʻi liʻiliʻi.
He aha nā mea e pili ana i ka viscosity o ka solution aqueous hydroxypropyl methyl cellulose?
1.Ka pilina me ka polymer: ʻo ka viscosity o ka hydroxypropyl methyl cellulose aqueous solution e like me ka polymer a i ʻole ke kaumaha mole, a hoʻonui ʻia me ka hoʻomaikaʻi ʻana o ke degere polymerization.ʻOi aku ka maopopo o kēia hopena i ka hihia o ka polymerization haʻahaʻa ma mua o ke ʻano o ka polymerization kiʻekiʻe.
2.ʻO ka pilina ma waena o ka viscosity a me ka noʻonoʻo: piʻi ka viscosity o ka hydroxypropyl methyl cellulose i loko o ka wai wai me ka hoʻonui ʻana o ka wai, a hiki i kahi hoʻololi liʻiliʻi ke hoʻololi nui i ka viscosity.
3.ʻO ka pilina ma waena o ka viscosity a me ka shear rate: Hōʻike ka hoʻāʻo i ka hydroxypropyl methyl cellulose ʻaʻohe loli nui ma ka liʻiliʻi ʻoki haʻahaʻa, a ua emi ka viscosity me ka piʻi ʻana o ka nui o ka shear rate.
4.ʻO ka pilina ma waena o ka viscosity a me ka mahana: hydroxypropyl methyl cellulose i hoʻopilikia nui ʻia e ka mahana, a emi ka viscosity me ka piʻi ʻana o ka mahana.
5.ʻO nā kumu ʻē aʻe: ʻo ka viscosity o ka hydroxypropyl methyl cellulose a me nā mea hoʻohui like ʻole, nā hopena, nā waiwai PH kekahi hopena.
Ke hana mākou i ka hoʻāʻo lab mea pono mākou e ʻike e pili ana i ke ʻano viscosity o ka hydroxypropyl methyl cellulose aqueous solution?
