Ka hana a me ka hoʻokaʻawale ʻana o HPMC

ʻO ka mānoanoa haʻahaʻa: hoʻohana nui ʻia ka 400 no ka palaki hoʻohaʻahaʻa ponoʻī, akā lawe ʻia mai ia mea.

Kumu: Haʻahaʻa ka mānoanoa, paʻa wai maikaʻi ʻole, akā maikaʻi nā waiwai hoʻohaʻahaʻa, kiʻekiʻe ka nui o ka mortar.

ʻO ka mānoanoa waena a me ka haʻahaʻa: 20000-40000 ka mea i hoʻohana nui ʻia no ka hoʻopili tile, caulking agent, anti-crack mortar, thermal insulation bonding mortar, etc.

Nā kumu: Hana maikaʻi, wai emi i hoʻohui ʻia, a me ka nui o ka paʻakai.

1. He aha nā hoʻohana 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 ka hoʻohana ʻana. I kēia manawa, ʻo ka hapa nui o nā huahana kūloko he ʻano kūkulu. I ke ʻano kūkulu, hoʻohana nui ʻia ka pauka putty, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka sima sima a me ke kāpili.

2. Ehia mau ʻano hydroxypropyl methylcellulose (HPMC) i loaʻa? He aha kā lākou hoʻohana?

——A: Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Hoʻopuehu koke nā huahana koke i ka wai anuanu a nalowale i loko o ka wai. ʻAʻohe mānoanoa o ka wai i kēia manawa no ka mea ua hoʻopuehu wale ʻia ka HPMC i loko o ka wai a ʻaʻole i hoʻoheheʻe maoli ʻia. Ma hope o 2 mau minuke, piʻi mālie ka mānoanoa o ka wai a hoʻokumu ʻia kahi colloid viscous maopopo. Hiki i nā huahana hoʻoheheʻe wela ke hoʻopuehu koke i ka wai wela a nalowale i ka wai wela ke hālāwai me ka wai anuanu. Ke hāʻule ka mahana i kahi mahana (ʻo ka huahana a kā mākou hui he 65 degere Celsius), ʻike mālie ʻia ka mānoanoa a hiki i ka hoʻokumu ʻia ʻana o kahi colloid viscous maopopo. Hiki ke hoʻohana ʻia ke ʻano hoʻoheheʻe wela no ka pauka putty a me ka mortar. I loko o ka glue wai a me ka pena, e kū mai ka clumping a ʻaʻole hiki ke hoʻohana ʻia. Loaʻa i ke ʻano koke kahi ākea o nā noi. Hiki ke hoʻohana ʻia no ka pauka putty, mortar, glue wai, a me ka pena me ka ʻole o nā contraindications.

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

——Pane: Ke ʻano hoʻoheheʻe wai wela: ʻOiai ʻaʻole hiki ke hoʻoheheʻe ʻia ka HPMC i ka wai wela, hiki ke hoʻopuehu like ʻia ka HPMC i ka wai wela i ka wā mua a hoʻoheheʻe koke ʻia ma hope o ka hoʻomaʻalili ʻana. Ua wehewehe ʻia ʻelua mau ʻano maʻamau ma lalo nei:

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℃. E hoʻohui mālie i ka hydroxypropyl methylcellulose me ka hoʻowali mālie. I ka wā mua, lana ka HPMC ma luna o ka ʻili wai, a laila hana mālie i kahi slurry, a hoʻomaʻalili me ka hoʻowali 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, e hoʻomehana iā ia i 70°C, e hoʻopuehu i ka HPMC e like me ke ʻano ma 1), a hoʻomākaukau i ka slurry wai wela; a laila e hoʻohui i ke koena o ka wai anuanu i ka slurry wai wela. slurry i loko o ka wai, e hoʻoulu a hoʻomaʻalili i ka hui ʻana.

ʻAno kāwili pauka: E kāwili i ka pauka HPMC me ka nui o nā mea pauka ʻē aʻe, e kāwili maikaʻi me ka mīkini wili, a laila e hoʻohui i ka wai e hoʻoheheʻe. I kēia manawa, hiki ke hoʻoheheʻe ʻia ka HPMC a ʻaʻole e hui pū, no ka mea, he wahi liʻiliʻi wale nō o HPMC i kēlā me kēia ʻāpana. Kihi liʻiliʻi. Hoʻoheheʻe koke ka pauka i ka wā e pili ai me ka wai. ——Hoʻohana nā mea hana pauka putty a me ka mortar i kēia ʻano hana. Hoʻohana ʻia ʻo 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?

——Pane: (1) Keʻokeʻo: ʻOiai ʻaʻole hoʻoholo ka keʻokeʻo inā maʻalahi ka hoʻohana ʻana o HPMC, inā hoʻohui ʻia nā mea hoʻomālamalama 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 maʻamau he 80 mesh a me 100 mesh, me 120 mesh ka liʻiliʻi. ʻO ka hapa nui o ka HPMC i hana ʻia ma Hebei he 80 mesh. ʻOi aku ka maikaʻi o ka maikaʻi o ka maikaʻi. (3) Hoʻoili kukui: E hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid moakaka, a nānā i kāna hoʻoili kukui. ʻOi aku ke kiʻekiʻe o ka hoʻoili kukui, 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 ea o nā reactors vertical ma mua o nā reactors horizontal, akā ʻaʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o ka maikaʻi o nā reactors vertical ma mua o nā reactors horizontal. Nui nā mea e hoʻoholo ai i ka maikaʻi o ka huahana. (4) Ke kaumaha kikoʻī: ʻOi aku ka nui o ke kaumaha kikoʻī a me ke kaumaha, ʻoi aku ka maikaʻi. ʻO ke kaumaha kikoʻī maʻamau ma muli o ka nui o ka hydroxypropyl i loko. ʻOi aku ka maikaʻi o ka paʻa ʻana o ka wai ma mua o ka nui o ka hydroxypropyl i loko o ka ʻili.

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

——Pane: ʻOkoʻa ka nui o ka HPMC i nā noi maoli e like me ke aniau, ka mahana, ka maikaʻi o ka calcium lehu kūloko, a me ke ʻano hoʻokomo. pauka ty a me ka "maikaʻi i koi ʻia e ka mea kūʻai aku". Ma ke ʻano laulā, aia ma waena o 4kg a me 5kg. 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 nui o ka pono o ka mortar, no laila ua lawa ka 150,000 yuan. A 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 he paʻa wai maikaʻi a me ka viscosity haʻahaʻa (70,000-80,000), ua maikaʻi. 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, ʻaʻole nui ka hopena o ka viscosity i ka paʻa ʻana o ka wai.

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

——A: 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 ke kiʻekiʻe o ka nui o ka hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai. Me ke kiʻekiʻe o ka mānoanoa, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai (ʻaʻole 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 caustic soda, acid, toluene, isopropyl alcohol, a pēlā aku.

9. He aha ke kuleana nui o HPMC i ka hoʻopili ʻana o ka pauka putty? Loaʻa iā ia kekahi hopena kemika?

——Pane: ʻEkolu mau hana nui o HPMC o ka hoʻomānoanoa ʻana, ka paʻa ʻana o ka wai a me ke kūkulu ʻana i ka pauka putty. Hoʻomānoanoa: Hiki i ka Cellulose ke hoʻomānoanoa i ka hoʻokuʻu ʻana, mālama i ka hoʻonā like a pale aku i ka sagging. Paʻa wai: E hoʻomaloʻo mālie i ka pauka putty a kōkua i ka hopena o ka calcium hina ma lalo o ka hana a ka wai. Kūkulu ʻana: He hopena lubricating ko Cellulose a hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo HPMC i kekahi mau hopena kemika a pāʻani wale i kahi hana kōkua. Ke hoʻohui ʻia ka pauka putty i ka wai a hoʻopili ʻia i ka paia, e hana ʻia kahi hopena kemika. I ka wā e hoʻokumu ʻia ai kahi mea hou, wehe ʻia ka pauka putty ma ka paia mai ka paia a wili ʻia i pauka ma mua o ka hoʻohana ʻana. ʻAʻole hana kēia no ka mea ua hoʻokumu ʻia kahi mea hou (calcium carbonate). ) i luna. ʻO nā ʻāpana nui o ka pauka kalipuna hina: 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 Hoʻoheheʻe ʻia ka kalipuna hina i ka wai a me ka ea CO2 Ma lalo o ka hana a ka kalipuna kalapona, mālama wale ka HPMC i ka wai a kōkua i ka kalipuna hina e pane maikaʻi aʻe, a ʻaʻole ia e komo i kekahi hopena ponoʻī.

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

A: Ma ka ʻōlelo maʻamau, ʻo nā non-ion he mau mea i hoʻokaʻawale ʻole i ka wai. ʻO ka ionization ke kaʻina hana e hoʻokaʻawale ai nā electrolytes i nā ion i hoʻopiʻi ʻia e neʻe manuahi ana i loko o kekahi mau mea hoʻoheheʻe (e laʻa, wai, waiʻona). No ka laʻana, ʻo ka sodium chloride (NaCl), ka paʻakai i hoʻopau ʻia i kēlā me kēia lā, hoʻoheheʻe ʻia i loko o ka wai a hoʻokaʻawale, e hana ana i nā ion sodium i hoʻopiʻi maikaʻi ʻia (Na+) a me nā ion chloride i hoʻopiʻi maikaʻi ʻole ʻia (Cl). ʻO ia hoʻi, ke kau ʻia ka HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i nā ion i hoʻopiʻi ʻia, akā aia ma ke ʻano molekala.
