ʻO HPMC ma ka ʻaʻahu Skim i ka noi, ke kuleana nui, inā paha he kemika?

Pane: HPMC i loko o ka ʻaʻahu Skim, mānoanoa, wai a me ke kūkulu ʻana o ʻekolu mau kuleana. Mānoanoa: hiki ke hoʻomānoanoa ʻia ka cellulose i ka hoʻokuʻu ʻia, i noho like ka hopena i luna a i lalo i ke kuleana o ke kau ʻana i ke kahe. Paʻa wai: e hoʻomaloʻo mālie i ka ʻaʻahu Skim, kōkua i ka calcium hina i ka hana o ka hopena wai. Kūkulu: lubrication cellulose, hiki ke hana i ka ʻaʻahu Skim i kūkulu maikaʻi ʻia. ʻAʻole komo ʻo HPMC i kekahi hopena kemika, akā pāʻani wale i kahi kuleana kākoʻo. ʻO ka ʻaʻahu Skim a me ka wai, ma ka paia, he hopena kemika, ma muli o ka hanauna o nā mea hou, ka paia o ka ʻaʻahu Skim i lalo mai ka paia, wili i ka pauka, a laila hoʻohana, ʻaʻole maikaʻi, no ka mea ua hoʻokumu ʻia kahi mea hou (calcium carbonate). ʻO nā ʻāpana nui o ka pauka kalipuna hina: Ca(OH)2, CaO a me kahi liʻiliʻi o ka hui ʻana o CaCO3, CaO+H2O=Ca(OH)2 – Ca(OH)2+CO2=CaCO3↓+H2O hina kalipuna i ka wai a me ka lewa ma lalo o ka hana a CO2, ka hoʻokumu ʻia ʻana o ka kalipuna kalapona, a me ka wai wale nō o HPMC, ʻoi aku ka maikaʻi o ka hopena o ka kalipuna hina kōkua, ʻaʻole i komo kāna iho i kekahi hopena.

ʻO HPMC ka non-ionic cellulose Ether, no laila he aha ka non-ionic?

A: Ma ke ʻano laulā, ʻo nā non-ion he mau mea ia ʻaʻole e ionize i loko o ka wai. ʻO ka ionization ka dissociation o kahi electrolyte i loko o nā ion i hoʻopiʻi ʻia e neʻe manuahi ana i loko o kahi solvent kikoʻī, e like me ka wai a i ʻole ka waiʻona. No ka laʻana, ʻo ka paʻakai a mākou e ʻai ai i kēlā me kēia lā - sodium chloride (NaCl) e hoʻoheheʻe ʻia i loko o ka wai a ionizes e hana i nā ion sodium neʻe manuahi (Na+) me kahi uku maikaʻi a me nā ion chloride (Cl) me kahi uku maikaʻi ʻole. ʻO ia hoʻi, ʻaʻole e hoʻokaʻawale ʻo HPMC i loko o ka wai i loko o nā ion i hoʻopiʻi ʻia, akā aia ma ke ʻano he mau molekala.

He aha ka pili o ka mahana gelation o ka hydroxypropyl methyl cellulose?

Pane: Pili ka mahana o ka gel o HPMC i ka nui o ka methoxyl. ʻO ka haʻahaʻa o ka nui o ka methoxyl, ʻo ke kiʻekiʻe o ka mahana o ka gel.

ʻAʻohe pilina o ka pauka ʻaʻahu Skim a me ka HPMC?

Pane: ʻO ka pauka kulu ʻaʻahu skim nui a me ke ʻano o ka calcium lehu he pilina nui loa ia, a ʻaʻole pili nui ka HPMC. ʻO ka haʻahaʻa o ka calcium o ka calcium hina a me ka hapa kūpono ʻole o CaO a me Ca(OH)2 i ka calcium hina e hoʻoulu ai i ka hāʻule ʻana o ka pauka. Inā he pilina me HPMC, a laila ʻo ka paʻa ʻole o ka wai o HPMC e hoʻoulu ai i ka nalowale o ka pauka.

He aha ka ʻokoʻa ma waena o ka hydroxypropyl methyl cellulose hiki ke hoʻoheheʻe ʻia i ka wai anu a me ka hydroxypropyl methyl cellulose hiki ke hoʻoheheʻe ʻia i ke kaʻina hana?

– Pane: ʻO ke ʻano hoʻonā wai anuanu HPMC ma hope o ka mālama ʻana i ka ʻili glyoxal, hoʻokomo i loko o ka wai anuanu e hoʻopuehu koke ʻia, akā ʻaʻole i hoʻoheheʻe maoli ʻia, piʻi ka mānoanoa, ua hoʻoheheʻe ʻia. ʻAʻole i mālama ʻia ka ʻili me ka glyoxal no ka mea hiki ke hoʻoheheʻe ʻia. Nui ka nui o ka glyoxal, wikiwiki ka hoʻopuehu ʻana, akā lohi ka mānoanoa, liʻiliʻi ka nui, ma ke ʻano ʻē.
