Ka hoʻohana ʻana o HPMC i ka pauka putty

1. He aha ka mānoanoa kūpono o HPMC?

——Pane: Ma keʻano laulā, ua lawa ka 100,000 yuan no ka pauka putty. ʻOi aku ke kiʻekiʻe o nā koi no ka mortar, a pono ka 150,000 yuan no ka hoʻohana maʻalahi. Eia kekahi, ʻo ka hana nui loa o HPMC ka paʻa ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka pauka putty, inā maikaʻi ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity (70,000-80,000), hiki nō hoʻi. ʻOiaʻiʻo, ʻo ke kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. Ke ʻoi aku ka viscosity ma mua o 100,000, e hoʻopilikia ka viscosity i ka paʻa ʻana o ka wai. ʻAʻole nui hou.

2. He aha nā ʻōkuhi loea nui oHPMC?

——Pane: ʻO ka nui o ka hydroxypropyl a me ka mānoanoa, hopohopo ka hapa nui o nā mea hoʻohana e pili ana i kēia mau ʻōkuhi ʻelua. ʻO ka poʻe me ka nui o ka hydroxypropyl he ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. ʻO ka mea me ka mānoanoa kiʻekiʻe he ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai, me ka pili (ʻaʻole loa), a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mea me ka mānoanoa kiʻekiʻe i ka sima sima.

3. He aha ka hana nui o ka hoʻopili ʻana o HPMC i ka pauka putty, a hana ia ma ke ʻano kemika?

——Pane: I loko o ka pauka putty, ʻekolu kuleana o HPMC o ka hoʻomānoanoa ʻana, ka paʻa ʻana o ka wai a me ke kūkulu ʻana. Hoʻomānoanoa: Hiki ke hoʻomānoanoa ʻia ka Cellulose e hoʻokuʻu a mālama i ka hopena like i luna a i lalo, a pale aku i ka sagging. Paʻa wai: e hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka calcium lehu e hana ma lalo o ka hana a ka wai. Kūkulu ʻana: He hopena lubricating ko Cellulose, hiki ke hana i ka pauka putty i kūkulu maikaʻi ʻia. ʻAʻole komo ʻo HPMC i kekahi hopena kemika, akā he hana kōkua wale nō. ʻO ka hoʻohui ʻana i ka wai i ka pauka putty a kau iā ia ma ka paia he hopena kemika, no ka mea, ua hoʻokumu ʻia nā mea hou. Inā ʻoe e wehe i ka pauka putty ma ka paia mai ka paia, e wili iā ia i pauka, a hoʻohana hou, ʻaʻole ia e hana no ka mea ua hoʻokumu ʻia nā mea hou (calcium carbonate). ) pū kekahi. ʻO nā ʻāpana nui o ka pauka kalipuna lehu: kahi hui ʻana o Ca(OH)2, CaO a me kahi liʻiliʻi o CaCO3, CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O Aia ka kalipuna lehu i loko o ka wai a me ka ea Ma lalo o ka hana a CO2, hoʻopuka ʻia ka kalipuna kalapona, ʻoiai ʻo HPMC e mālama wale i ka wai, e kōkua ana i ka hopena maikaʻi o ka kalipuna lehu, a ʻaʻole ia e komo i kekahi hopena ponoʻī.

4. ʻO HPMC kahi ʻetera cellulose non-ionic, no laila he aha ka non-ionic?

——Pane: Ma ka ʻōlelo maʻamau, ʻo nā non-ion he mau mea ia e ʻole e ionize i loko o ka wai. ʻO ka ionization ke kaʻina hana e hoʻokaʻawale ʻia ai kahi electrolyte i loko o nā ion i hoʻopiʻi ʻia e hiki ke neʻe manuahi i loko o kahi mea hoʻoheheʻe kikoʻī (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, hoʻoheheʻe ʻia i loko o ka wai a ionize e hana i nā ion sodium neʻe manuahi (Na+) i hoʻopiʻi maikaʻi ʻia a me nā ion chloride (Cl) i hoʻopiʻi maikaʻi ʻole ʻia. ʻO ia hoʻi, ke kau ʻia ʻo HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i loko o nā ion i hoʻopiʻi ʻia, akā aia ma ke ʻano o nā molekala.

5. Aia kekahi pilina ma waena o ka kulu ʻana o ka pauka putty a me HPMC?

——Pane: ʻO ka nalowale o ka pauka o ka pauka putty e pili nui ana i ke ʻano o ka calcium lehu, a ʻaʻohe pili iki me ka HPMC. ʻO ka haʻahaʻa o ka calcium o ka calcium hina a me ka lakio kūpono ʻole o CaO a me Ca(OH)2 i ka calcium hina e hoʻoulu ai i ka nalowale o ka pauka. Inā pili ia i ka HPMC, a laila inā maikaʻi ʻole ka paʻa ʻana o ka wai o HPMC, e hoʻoulu pū ia i ka nalowale o ka pauka

6. Pehea e koho ai i kahi kūponoHPMCno nā kumu like ʻole?

——Pane: ʻO ka hoʻopili ʻana i ka pauka putty: haʻahaʻa nā koi, a ʻo ka mānoanoa he 100,000, ua lawa ia. ʻO ka mea nui ka mālama pono ʻana i ka wai. Hoʻopili ʻana i ka mortar: ʻoi aku ka kiʻekiʻe o nā koi, kiʻekiʻe ka mānoanoa, ʻoi aku ka maikaʻi o 150,000. Hoʻopili ʻana i ke kāpili: pono nā huahana koke me ka mānoanoa kiʻekiʻe.
