ʻO ka hana a me ka hoʻokaʻawale ʻana o HPMC

ʻO ka viscosity haʻahaʻa: Hoʻohana nui ʻia ʻo 400 no ka mortar self-leveling, akā lawe ʻia mai.

Ke kumu: Haʻahaʻa viscosity, maikaʻi ka paʻa ʻana o ka wai, akā maikaʻi nā waiwai pae, kiʻekiʻe mortar density.

Medium a haʻahaʻa viscosity: 20000-40000 ka mea nui no ka tile adhesive, caulking agent, anti-crack mortar, thermal insulation bonding mortar, etc.

Nā kumu: ʻO ka hiki ke hana maikaʻi, ka liʻiliʻi o ka wai i hoʻohui ʻia, a me ka nui o ka mortar kiʻekiʻe.

1. He aha nā mea hoʻohana nui o ka hydroxypropyl methylcellulose (HPMC)?

——A: Hoʻohana nui ʻia ʻo HPMC i nā mea kūkulu hale, nā uhi, nā resins synthetic, ceramics, lāʻau lapaʻau, meaʻai, textiles, mahiʻai, mea hoʻonaninani, paka a me nā ʻoihana ʻē aʻe. Hiki ke hoʻokaʻawale ʻia ka HPMC i: papa hana, papa meaʻai a me ka papa lāʻau lapaʻau e like me ka hoʻohana ʻana. I kēia manawa, ʻo ka hapa nui o nā huahana home ka pae kūkulu. I ka papa hana, hoʻohana nui ʻia ka pauka putty, ma kahi o 90% e hoʻohana ʻia no ka pauka putty, a hoʻohana ʻia ke koena no ka mortar sima a me ke kāpili.

2. Ehia na ano o ka hydroxypropyl methylcellulose (HPMC) malaila? He aha kā lākou hoʻohana?

——A: Hiki ke hoʻokaʻawale ʻia ka HPMC i ke ʻano koke a me ke ʻano hoʻoheheʻe wela. Puka koke nā huahana i ka wai anuanu a nalowale i ka wai. ʻAʻohe viscosity o ka wai i kēia manawa no ka mea ua hoʻopuehu wale ka HPMC i ka wai a ʻaʻole i hoʻoheheʻe maoli ʻia. Ma hope o 2 mau minuke, piʻi mālie ka viscosity o ka wai a hoʻokumu ʻia kahi colloid viscous transparent. Hiki ke hoʻopuehu koke nā huahana wela 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 o kā mākou hui he 65 degere Celsius), ʻike mālie ka viscosity a hiki i ka hoʻokumu ʻana o kahi colloid viscous māmā. Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela no ka pauka putty a me ka hamo. I loko o ke kāpili wai a me ka pena, hiki mai ka clumping a ʻaʻole hiki ke hoʻohana. Loaʻa i ka ʻano koke ka laulā o nā noi. Hiki ke hoʻohana ʻia no ka pauka putty, mortar, ke kolu 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: No ka mea 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 hemo koke ma hope o ka hoʻoluʻu ʻana. ʻElua mau ala maʻamau i wehewehe ʻia ma lalo nei:

1) E hoʻokomo i ka nui o ka wai wela i loko o ka ipu a hoʻomehana iā ia ma kahi o 70 ℃. Hoʻohui mālie i ka hydroxypropyl methylcellulose me ka hoʻoulu lohi. I ka hoʻomaka ʻana, lana ʻo HPMC ma ka ʻili o ka wai, a laila hana mālie i ka slurry, a maʻalili me ka hoʻoulu ʻana.

2). E hoʻohui i ka 1/3 a i ʻole 2/3 o ka nui o ka wai i makemake ʻia i loko o ka pahu, e wela iā 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, hoʻoulu a hoʻomaha i ka hui.

ʻO ke ʻano o ka hui ʻana i ka pauda: E hui pū i ka pauka HPMC me ka nui o nā mea pauda ʻē aʻe, e hui pono me ka mea huila, a laila hoʻohui i ka wai e hoʻoheheʻe. I kēia manawa, hiki ke hoʻoheheʻe ʻia ka HPMC a ʻaʻole e hui pū, no ka mea he liʻiliʻi wale nō ka HPMC i kēlā me kēia ʻāpana. kihi liʻiliʻi. Hoʻoheheʻe koke ʻia ka pauda i ka pili ʻana me ka wai. ——Hoohana na mea hana pauda a me ka motar i keia ano. Hoʻohana ʻia ʻo Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa wai i ka mortar pauka putty.

4. Pehea e hoʻoholo ai i ka maikaʻi o ka hydroxypropyl methylcellulose (HPMC) maʻalahi a intuitively?

——Pane: (1) Keokeo: ʻOiai ʻaʻole ʻike ka keʻokeʻo inā he maʻalahi ka HPMC e hoʻohana, inā hoʻohui ʻia nā mea hoʻomālamalama i ka wā o ka hana ʻana, e hoʻopilikia ia i kona maikaʻi. Eia naʻe, ʻo ka hapa nui o nā huahana maikaʻi he keʻokeʻo maikaʻi. (2) Fineness: ʻO ka maikaʻi o ka HPMC he 80 mesh a me 100 mesh, me ka 120 mesh he emi. ʻO ka hapa nui o ka HPMC i hana ʻia ma Hebei he 80 mesh. ʻO ka ʻoi aku ka maikaʻi ʻoi aku ka maikaʻi. (3) Ka hoʻouna māmā: E hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid akaka, a nānā i kāna transmittance māmā. ʻOi aku ka kiʻekiʻe o ka transmittance māmā, ʻoi aku ka maikaʻi, e hōʻike ana he liʻiliʻi nā mea hiki ʻole ke hoʻololi i loko. ʻOi aku ka maikaʻi o ka ea o nā reactors vertical ma mua o nā reactors horizontal, akā ʻaʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o nā reactors vertical ma mua o nā reactors horizontal. Nui nā kumu e hoʻoholo ai i ka maikaʻi o ka huahana. (4) Kaumaha kikoʻī: ʻO ka nui o ka umekaumaha kikoʻī a me ke kaumaha, ʻoi aku ka maikaʻi. ʻO ka umekaumaha kikoʻī maʻamau ma muli o ka nui o ka hydroxypropyl content i loko. ʻOi aku ka nui o ka hydroxypropyl content, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai.

5. He aha ke ʻano o ka hydroxypropyl methylcellulose (HPMC) i ka pauka putty?

——Pane: ʻOkoʻa ke ʻano o ka HPMC i nā noi maoli e like me ke aniau, ka mahana, ka maikaʻi o ka calcium lehu kūloko, a me ke kumu hoʻokomo. ty pauda a me ka "kūpono-koi maikaʻi". Ma ka ʻōlelo maʻamau, 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 nui o ka pauka putty ma Guizhou he 5 kg i ke kauwela a he 4.5 kg i ka hoʻoilo;

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

——Pane: He 100,000 yuan ke kumu kuai o ka pauda Putty, a he nui aku ka pono o ka paakai, no laila ua lawa ka 150,000 yuan. A ʻo ka hana koʻikoʻi o ka HPMC ʻo ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka pauka putty, inā lōʻihi ka paʻa ʻana o ka wai a me ka viscosity haʻahaʻa (70,000-80,000), ua maikaʻi. ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka viscosity, ʻoi aku ka maikaʻi o ka paʻa wai pili. Ke ʻoi aku ka viscosity ma mua o 100,000, liʻiliʻi ka hopena o ka viscosity i ka paʻa ʻana o ka wai.

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

——A: Hydroxypropyl content and viscosity, ka hapanui o nā mea hoʻohana e hopohopo nei i kēia mau hōʻailona ʻelua. ʻOi aku ka nui o ka hydroxypropyl content, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. Me ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai (ʻaʻole loa), a me ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mortar sima.

8. He aha nā mea maka nui o ka hydroxypropyl methylcellulose (HPMC)?

—— A: ʻO nā mea waiwai nui o ka hydroxypropyl methylcellulose (HPMC): ka pulupulu hoʻomaʻemaʻe, ka methyl chloride, propylene oxide, nā mea waiwai ʻē aʻe e pili ana i ka soda caustic, acid, toluene, isopropyl alcohol, etc.

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

——Pane: ʻEkolu mau hana nui o ka HPMC o ka mānoanoa, ka paʻa wai a me ke kūkulu ʻana i ka pauda putty. Mānoanoa: Hiki i ka Cellulose ke mānoanoa i ka hoʻokuʻu ʻia ʻana, mālama i ka hoʻonā ʻano like ʻole a pale 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 o ka wai. Hana: He hopena lubricating ka Cellulose a hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo HPMC i nā 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. Ke hoʻokumu ʻia kahi mea hou, hoʻoneʻe ʻia ka pauda putty ma ka paia mai ka paia a lepo i ka pauka ma mua o ka hoʻohana ʻana. ʻAʻole pono kēia no ka mea ua hoʻokumu ʻia kahi mea hou (calcium carbonate). ) i luna. ʻO nā mea nui o ka pauka calcium hina: kahi hui o Ca(OH)2, CaO a me kahi liʻiliʻi o CaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O ʻO ka calcium hina. hoʻoheheʻe i ka wai a me ka ea CO2 Ma lalo o ka hana o ka calcium carbonate, HPMC wale nō ka mālama ʻana i ka wai a kōkua i ka calcium hina e hana maikaʻi aʻe, ʻaʻole ia e komo i kekahi ʻano hana ponoʻī.

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

A: Ma ka ʻōlelo a ka poʻe kamaʻāina, ʻo nā non-ions nā mea ʻaʻole i hoʻoheheʻe ʻia i ka wai. ʻO ka Ionization ke kaʻina hana e hoʻokaʻawale ai nā electrolytes i loko o ka neʻe manuahi i nā ion i hoʻopaʻa ʻia i kekahi mau mea hoʻoheheʻe (e laʻa, ka wai, ka 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 hoʻoheheʻe ʻia, e hoʻohua ana i nā ion sodium (Na+) i hoʻopaʻa ʻia me ka maikaʻi ʻole (Cl). ʻO ia hoʻi, ke kau ʻia ʻo HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i nā ion i hoʻopaʻa ʻia, akā aia ma ke ʻano molekala.
