He aha nā pilikia maʻamau o ka hydroxypropyl methylcellulose?

1. He aha ka hoʻohana nui ʻana ohydroxypropyl methylcellulose (HPMC)?

Hoʻohana nui ʻia ka Hydroxypropyl methylcellulose 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 Hydroxypropyl methylcellulose i ke ʻano kūkulu hale, ke ʻano meaʻai a me ka ʻano lāʻau lapaʻau e like me kāna noi. I kēia manawa, ʻo ka hapa nui o nā huahana kūloko he ʻano kūkulu hale. I ke ʻano kūkulu hale, hoʻohana nui ʻia 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 nā ʻokoʻa o kā lākou hoʻohana ʻana?

Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Hoʻopuehu koke nā huahana ʻano koke ke hālāwai lākou me 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 loko o ka wai me ka ʻole o ka hoʻoheheʻe maoli ʻana. Ma hope o 2 mau minuke, piʻi mālie ka mānoanoa o ka wai, e hana ana i kahi colloid viscous maopopo. ʻO nā huahana hoʻoheheʻe wela, i ka wā e hui ai me ka wai anuanu, hiki ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela. Ke hāʻule ka mahana i kahi mahana, e 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 loaʻa kahi hanana hui 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 ka glue wai a me ka pena, me ka ʻole o nā contraindications.

3. He aha nā ʻano hoʻoheheʻe ʻana o ka hydroxypropyl methylcellulose (HPMC)?

Ke ʻano hoʻoheheʻe wai wela: ʻOiai ʻaʻole 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 hoʻokomo 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 ma lalo o ka hoʻoulu mālie ʻana, i ka wā mua ua lana ka HPMC ma luna o ka wai, a laila hana mālie i kahi slurry, kahi i hoʻomaʻalili ʻia ma lalo o 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 slurry wai wela, 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 hoʻopili ʻana, no ka mea, he HPMC liʻiliʻi wale nō ma kēlā me kēia kihi liʻiliʻi o ka pauka, e hoʻoheheʻe koke ʻia ke hoʻopili ʻia me ka wai. ——Ke hoʻohana nei nā mea hana pauka Putty a me ka mortar i kēia ʻano hana. [Hoʻohana ʻia ka Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mea hoʻomānoanoa a me ka mea paʻa 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?

(1) Keʻokeʻo: ʻOiai ʻaʻole hiki i ka keʻokeʻo ke hoʻoholo inā maʻalahi ka hoʻohana ʻana i ka HPMC, a inā hoʻohui ʻia nā mea hoʻokeʻokeʻo i ka wā o ke kaʻina hana, e hoʻopilikia ia i kona maikaʻi. Eia nō naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi.

(2) Maikaʻi: ʻO ka maikaʻi o ka HPMC ma ke ʻano maʻamau he 80 mesh a me 100 mesh, ʻoi aku ka liʻiliʻi o 120 mesh, a ʻo ka hapa nui o HPMC i hana ʻia ma Hebei he 80 mesh. ʻO ka maikaʻi o ka maikaʻi, ma ke ʻano laulā, ʻoi aku ka maikaʻi.

(3) Hoʻoili: E hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid moakaka, a e nānā i kona hoʻoili. ʻO ke kiʻekiʻe o ka hoʻoili, ʻoi aku ka maikaʻi, e hōʻike ana he emi ka insoluble i loko. ʻOi aku ka maikaʻi o ka permeability o nā reactors vertical, a ʻoi aku ka ʻino o nā reactors horizontal, akā ʻaʻole ia he manaʻo he ʻoi aku ka maikaʻi o ke ʻano o nā reactors vertical ma mua o nā reactors horizontal, a ua hoʻoholo ʻia ke ʻano o ka huahana e nā kumu he nui.

(4) Ke kaumaha kikoʻī: ʻOi aku ka nui o ke kaumaha kikoʻī, ʻoi aku ka maikaʻi o ke kaumaha. Nui ka kikoʻī, ma ke ʻano nui no ka mea he kiʻekiʻe ka nui o ka hui hydroxypropyl i loko, a he kiʻekiʻe ka nui o ka hui hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.

5. He aha ka nui o ka hydroxypropyl methylcellulose (HPMC) i loko o ka pauka putty?

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, 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; ʻo ka nui o ka pauka putty ma Yunnan he liʻiliʻi iki, maʻamau he 3 kg a 4 kg, a pēlā aku.

6. He aha ka mānoanoa kūpono o ka hydroxypropyl methylcellulose (HPMC)?

ʻO ka pauka putty ma ke ʻano laulā ua lawa ia no 100,000 yuan, a ʻoi aku ke kiʻekiʻe o nā koi no ka mortar, a pono 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.

7. He aha nā ʻōkuhi loea nui o ka hydroxypropyl methylcellulose (HPMC)?

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 hoʻohālikelike (ʻaʻole loa), a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mea me ka mānoanoa kiʻekiʻe i ka sima sima.

8. He aha nā mea maka nui ohydroxypropyl methylcellulose (HPMC)?

ʻO nā mea maka nui o ka hydroxypropyl methylcellulose (HPMC): pulupulu i hoʻomaʻemaʻe ʻia, methyl chloride, propylene oxide, a me nā mea maka ʻē aʻe, caustic soda, acid, toluene, isopropanol, a pēlā aku.

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

I loko o ka pauka putty, ʻekolu kuleana o HPMC o ka mānoanoa, ka paʻa ʻana o ka wai a me ke kūkulu ʻana. Mānoanoa: 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 pane 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). 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.

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

Ma nā huaʻōlelo maʻamau, ʻo nā non-ion he mau mea i hoʻokaʻawale ʻole ʻia i loko o ka wai. ʻO ka ionization e pili ana i 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 hoʻokaʻawale 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, i ka wāHPMCke kau ʻia i loko o ka wai, ʻaʻole ia e hoʻokaʻawale ʻia i loko o nā ion i hoʻopiʻi ʻia, akā e noho ma ke ʻano o nā molekala.
