1. He aha ke kumu nui o ka hydroxypropyl methylcellulose (HPMC)?
——A: Hoʻohana nui ʻia ka HPMC i nā mea kūkulu hale, nā uhi, nā resins synthetic, nā keramika, nā lāʻau lapaʻau, ka meaʻai, nā lole, ka mahiʻai, nā mea hoʻonani, ka paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i: ke ʻano kūkulu, ke ʻano meaʻai a me ka ʻano lāʻau lapaʻau e like me ke kumu. I kēia manawa, ʻo ka hapa nui o nā huahana kūloko he ʻano kūkulu. I ke ʻano kūkulu, nui loa ka nui o ka pauka putty, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a ʻo ke koena e hoʻohana ʻia no ka sima sima a me ke kāpili.
2. Aia kekahi mau ʻano hydroxypropyl methylcellulose (HPMC), a he aha ka ʻokoʻa o kā lākou hoʻohana ʻana?
——Pane: Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Hoʻopuehu koke nā huahana ʻano koke i ka wai anuanu a nalowale i loko o ka wai. I kēia manawa, ʻaʻohe mānoanoa o ka wai, no ka mea, ua hoʻopuehu wale ʻia ka HPMC i ka wai a ʻaʻohe hoʻoheheʻe maoli. Ma hope o 2 mau minuke, ua piʻi mālie ka mānoanoa o ka wai, e hana ana i kahi colloid viscous maopopo. Hiki ke hoʻopuehu koke ʻia nā huahana hoʻoheheʻe wela, i ka wā e hālāwai ai me ka wai anuanu, i ka wai wela, a nalowale i ka wai wela. Ke hāʻule ka mahana i kahi mahana (ʻo ka huahana o kā mākou hui he 65 degere Celsius), ʻike mālie ʻia ka mānoanoa a hiki i ka hana ʻana i kahi colloid viscous maopopo. Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i ka pauka putty a me ka mortar. I loko o ka glue wai a me ka pena, e hana ʻia ka hanana clumping a ʻaʻole hiki ke hoʻohana ʻia. Loaʻa i ke ʻano koke kahi ākea o nā noi. Hiki ke hoʻohana ʻia i loko o ka pauka putty a me ka mortar, a me ke glue wai a me ka pena, me ka ʻole o nā contraindications.
3. He aha nā ʻano hoʻoheheʻe ʻana o ka hydroxypropyl methylcellulose (HPMC)?
——Pane: Ke ʻano hoʻoheheʻe wai wela: ʻOiai ʻaʻole i hoʻoheheʻe ʻia ka HPMC i ka wai wela, hiki ke hoʻopuehu like ʻia ka HPMC i ka wai wela i ka wā mua, a laila hoʻoheheʻe koke ʻia ke hoʻomaʻalili ʻia. Ua wehewehe ʻia ʻelua mau ʻano maʻamau penei:
1) E kau i ka nui o ka wai wela e pono ai i loko o ka ipu a hoʻomehana iā ia a hiki i kahi o 70°C. Ua hoʻohui mālie ʻia ka hydroxypropyl methylcellulose me ka hoʻoulu mālie ʻana, i ka wā mua ua lana ka HPMC ma luna o ka wai, a laila ua hana mālie i kahi slurry, kahi i hoʻomaʻalili ʻia me ka hoʻoulu ʻana.
2), e hoʻohui i ka 1/3 a i ʻole 2/3 o ka nui o ka wai e pono ai i loko o ka ipu, a hoʻomehana iā ia i 70 ° C, e like me ke ʻano o 1), e hoʻopuehu i ka HPMC, e hoʻomākaukau i ka slurry wai wela; a laila e hoʻohui i ke koena o ka wai anuanu i ka wai wela I loko o ka slurry, ua hoʻomaʻalili ʻia ka hui ʻana ma hope o ka hoʻoulu ʻana.
ʻAno kāwili pauka: E kāwili i ka pauka HPMC me ka nui o nā mea pauka ʻē aʻe, e kāwili maikaʻi me ka mea kāwili, a laila e hoʻohui i ka wai e hoʻoheheʻe, a laila hiki ke hoʻoheheʻe ʻia ka HPMC i kēia manawa me ka ʻole o ka hui pū ʻana, no ka mea, he HPMC liʻiliʻi wale nō ma kēlā me kēia kihi liʻiliʻi. E hoʻoheheʻe koke ʻia ka pauka i ka wā e pili ana me ka wai. ——Hoʻohana ʻia kēia ʻano hana e nā mea hana pauka putty a me ka mortar. [Hoʻohana ʻia ka Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mea hoʻomānoanoa a me ka mea mālama wai i loko o ka mortar pauka putty. ]
4. Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methylcellulose (HPMC) me ka maʻalahi a me ka naʻauao?
——Pane: (1) Keʻokeʻo: ʻOiai ʻaʻole hiki i ke keʻokeʻo ke hoʻoholo inā maʻalahi ka hoʻohana ʻana o HPMC, a inā hoʻohui ʻia kahi mea hoʻomālamalama i ke kaʻina hana, e hoʻopilikia ia i kona maikaʻi. Eia nō naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi. (2) Fineness: ʻO ka fineness o HPMC maʻamau he 80 mesh a me 100 mesh, a ʻoi aku ka liʻiliʻi o 120 mesh. ʻO ka hapa nui o HPMC i hana ʻia ma Hebei he 80 mesh. ʻOi aku ka maikaʻi o ka fineness, ʻoi aku ka maikaʻi. (3) Transmittance: E kau i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid moakaka, a nānā i kona transmittance. ʻOi aku ke kiʻekiʻe o ka transmittance, ʻoi aku ka maikaʻi, e hōʻike ana he emi nā mea hiki ʻole ke hoʻoheheʻe ʻia i loko. ʻOi aku ka maikaʻi o ka permeability o ka reactor vertical, a ʻoi aku ka ʻino o ka reactor horizontal, akā ʻaʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o ka maikaʻi o ka reactor vertical ma mua o ka reactor horizontal, a he nui nā mea e hoʻoholo ai i ka maikaʻi o ka huahana. (4) Ke kaumaha kikoʻī: ʻoi aku ka nui o ke kaumaha kikoʻī, ʻoi aku ka maikaʻi o ke kaumaha. He nui ke kaumaha kikoʻī, ma ke ʻano nui no ka mea he kiʻekiʻe ka ʻike hydroxypropyl i loko, a kiʻekiʻe ka ʻike hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.
5. ʻO ka nui o ka hydroxypropyl methylcellulose (HPMC) i loko o ka pauka putty?
——Pane: ʻOkoʻa ka nui o ka HPMC i hoʻohana ʻia i nā hana kūpono ma muli o ke aniau, ka mahana, ka maikaʻi o ka calcium lehu kūloko, ke ʻano o ka pauka putty a me ka "maikaʻi e pono ai nā mea kūʻai aku". Ma ke ʻano laulā, aia ma waena o 4 kg a me 5 kg. No ka laʻana, ʻo ka hapa nui o ka pauka putty ma Beijing he 5 kg; ʻo ka hapa nui o ka pauka putty ma Guizhou he 5 kg i ke kauwela a me 4.5 kg i ka hoʻoilo;
6. He aha ka mānoanoa kūpono o ka hydroxypropyl methylcellulose (HPMC)?
——Pane: ʻO ke kumukūʻai maʻamau o ka pauka Putty he 100,000 yuan, a ʻoi aku ka koi o ka mortar, a maʻalahi hoʻi e hoʻohana ma 150,000 yuan. Eia kekahi, ʻo ke kuleana nui o HPMC ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka pauka putty, inā maikaʻi ka mālama ʻana i ka wai a haʻahaʻa ka viscosity (70,000-80,000), hiki nō hoʻi. ʻOiaʻiʻo, ʻoi aku ke kiʻekiʻe o ka viscosity, a ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Ke ʻoi aku ka viscosity ma mua o 100,000, ʻaʻole nui ka hopena o ka viscosity i ka mālama ʻana i ka wai.
7. He aha nā ʻōkuhi loea nui o ka hydroxypropyl methylcellulose (HPMC)?
——Pane: ʻO ka nui o ka hydroxypropyl a me ka mānoanoa, mālama ka hapa nui o nā mea hoʻohana i kēia mau ʻōkuhi ʻelua. ʻO ke kiʻekiʻe o ka nui o ka hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. ʻO ka mānoanoa kiʻekiʻe, ka paʻa ʻana o ka wai, ʻoi aku ka maikaʻi (ma mua o ka paʻa loa), a me ke kiʻekiʻe o ka mānoanoa, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka sima sima.
8. He aha nā mea nui o ka hydroxypropyl methylcellulose (HPMC)?
—— A: ʻO nā mea maka nui o ka hydroxypropyl methylcellulose (HPMC): pulupulu i hoʻomaʻemaʻe ʻia, methyl chloride, propylene oxide, nā mea maka ʻē aʻe e komo pū ana me ka flake alkali, acid, toluene, isopropanol, a pēlā aku.
9. He aha ke kuleana nui o HPMC i ka hoʻopili ʻana o ka pauka putty, a aia kekahi kemika?
——Pane: ʻEkolu mau hana a HPMC o ka hoʻomānoanoa ʻana, ka paʻa ʻana o ka wai a me ke kūkulu ʻana i ka pauka putty. Hoʻomānoanoa: Hiki ke hoʻomānoanoa ʻia ka Cellulose e hoʻokuʻu, e mālama i ka hopena like a kūlike, a pale aku i ka sagging. Paʻa wai: E hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka hopena o ka lehu calcium ma lalo o ka hana a ka wai. Kūkulu ʻana: He hopena lubricating ko Cellulose, hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo HPMC i kekahi hopena kemika a 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. Ma muli o ka hoʻokumu ʻia ʻana o nā mea hou, e lawe 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). 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 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 a kōkua i ka hopena maikaʻi o ka kalipuna lehu, a ʻaʻole ia e komo i kekahi hopena ponoʻī.
10. ʻO HPMC ka non-ionic cellulose ether, no laila he aha ka non-ionic?
- Pane: Ma nā huaʻōlelo maʻamau, ʻo nā non-ion he mau mea i hoʻokaʻawale ʻole ʻia 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 neʻe manuahi ana i loko o kahi mea hoʻoheheʻe kikoʻī (e like me ka wai, ka waiʻona). No ka laʻana, ʻo ka sodium chloride (NaCl), ka paʻakai i ʻai ʻia i kēlā me kēia lā, hoʻoheheʻe ʻia i loko o ka wai a hoʻokaʻawale ʻia e hana i nā ion sodium (Na+) e neʻe manuahi ana 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.
