1. He aha ka inoa o ka hydroxypropyl methylcellulose?
——Pane: Hydroxypropyl Methyl Cellulose, English: Hydroxypropyl Methyl Cellulose Abbreviation: HPMC or MHPC Alias: Hypromellose;Cellulose Hydroxypropyl Methyl Ether;Hypromellose, Cellulose, 2-hydroxypropylmethyl Cellulose etera.Cellulose hydroxypropyl methyl ether Hyprolose.
2. He aha ka noi nui o ka hydroxypropyl methylcellulose (HPMC)?
——Pane: Hoʻohana nui ʻia ʻo HPMC i nā mea hana, nā uhi, nā resins synthetic, ceramics, lāʻau lapaʻau, meaʻai, textiles, mahiʻai, mea hoʻonaninani, paka a me nā ʻoihana ʻē aʻe.Hiki ke hoʻokaʻawale ʻia ka HPMC i ka papa hana, ka meaʻai a me ka lāʻau lapaʻau e like me ke kumu.I kēia manawa, ʻo ka hapa nui o nā huahana home he papa kūkulu hale.I ka papa hana, hoʻohana ʻia ka pauka putty i ka nui, ma kahi o 90% ka hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka mortar sima a me ke kāpili.
3. Nui nā ʻano o ka hydroxypropyl methylcellulose (HPMC), a he aha nā ʻokoʻa o kā lākou hoʻohana ʻana?
——Pane: Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano wela wela.Puka koke nā ʻano huahana i ka wai anuanu a nalowale i loko o ka wai.I kēia manawa, ʻaʻohe viscosity o ka wai no ka mea ua hoʻopuehu wale ʻia ka HPMC i ka wai me ka ʻole o ka hemo maoli.Ma kahi o 2 mau minuke, piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous transparent.ʻO nā huahana hoʻoheheʻe wela, ke hui ʻia me ka wai anuanu, hiki ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela.Ke hāʻule ka mahana i kekahi mahana, e ʻike mālie ʻia ka viscosity a hiki i ka hana ʻana i kahi colloid viscous transparent.Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i ka pauka putty a me ka mortar.I loko o ke kāpili wai a me ka pena, e hui pū ʻia nā mea ʻaʻole hiki ke hoʻohana.Loaʻa i ka ʻano koke ka laulā o nā noi.Hiki ke hoʻohana ʻia i loko o ka pauka putty a me ka mortar, a me ka wai kelu a me ka pena, me ka ʻole o nā contraindications.
4. Pehea e koho ai i kahi hydroxypropyl methylcellulose (HPMC) kūpono no nā kumu like ʻole?
——Pane:: Ka hoohana ana i ka pauda putty: He haahaa na koi, a he 100,000 ka viscosity, ua lawa.ʻO ka mea nui e mālama pono i ka wai.Ka hoʻohana ʻana i ka mortar: nā koi kiʻekiʻe, kiʻekiʻe viscosity, 150,000 ʻoi aku ka maikaʻi.Ka hoʻohana ʻana i ke kāpili: pono nā huahana koke me ka viscosity kiʻekiʻe.
5. He aha ka mea e pono e hoʻolohe i ka noi maoli o ka pilina ma waena o ka viscosity a me ka mahana o HPMC?
——Pane: Ua like ka viscosity o HPMC me ka wela, ʻo ia hoʻi, piʻi ka viscosity i ka emi ʻana o ka mahana.ʻO ka viscosity o kahi huahana a mākou e ʻōlelo pinepine ai e pili ana i ka hopena hoʻāʻo o kāna 2% aqueous solution ma kahi mahana o 20 degere Celsius.
Ma nā hoʻohana pono, pono e hoʻomaopopo ʻia ma nā wahi me nā ʻokoʻa wela nui ma waena o ke kauwela a me ka hoʻoilo, ua ʻōlelo ʻia e hoʻohana i kahi viscosity haʻahaʻa haʻahaʻa i ka hoʻoilo, ʻoi aku ka maikaʻi o ke kūkulu ʻana.A i ʻole, ke haʻahaʻa ka mahana, e piʻi ka viscosity o ka cellulose, a kaumaha ka lima i ka wā e ʻoki ai.
Medium viscosity: 75000-100000 i hoʻohana nui ʻia no ka putty
Ke kumu: mālama maikaʻi i ka wai
ʻO ka viscosity kiʻekiʻe: 150000-200000 Hoʻohana nui ʻia no ka polystyrene particle thermal insulation mortar rubber powder and vitrified microbead thermal insulation mortar.
Ke kumu: He kiʻekiʻe ka viscosity, ʻaʻole maʻalahi ka hāʻule ʻana o ka mortar, hāʻule, a hoʻomaikaʻi ʻia ke kūkulu ʻana.
6. ʻO ka HPMC he cellulose ether non-ionic, no laila he aha ka non-ionic?
——Pane: Ma ka ʻōlelo a ka poʻe kamaʻāina, ʻo ka non-ions he mau mea ʻaʻole i ionize i ka wai.ʻO ka Ionization e pili ana i ke kaʻina hana i hoʻokaʻawale ʻia kahi electrolyte i nā ion i hoʻopaʻa ʻia e hiki ke neʻe manuahi i loko o kahi mea hoʻoheheʻe (e like me ka wai, ka waiʻona).No ka laʻana, ʻo ka sodium chloride (NaCl), ka paʻakai a mākou e ʻai ai i kēlā me kēia lā, e hoʻoheheʻe ʻia i loko o ka wai a e hoʻoheheʻe ʻia e hana i nā ion sodium hiki ke hoʻoneʻe ʻia (Na+) i hoʻoili maikaʻi ʻia a me nā ion chloride (Cl) i hoʻoili ʻole ʻia.ʻO ia hoʻi, ke hoʻokomo ʻia ka HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i loko o nā ion i kau ʻia, akā aia ma ke ʻano o nā mole.
