Hoʻokaʻawale a hoʻohana i ka hydroxypropyl methylcellulose

HPMC viscosity haʻahaʻa: Hoʻohana nui ʻia ʻo HPMC 400 no ka mortar hoʻonaʻauao iho, akā lawe ʻia mai.

Ke kumu: He haʻahaʻa ka viscosity, ʻoiai ʻaʻole maikaʻi ka paʻa ʻana o ka wai, akā maikaʻi ka pae ʻana, a ʻoi aku ka nui o ka mortar density.

Medium a me haʻahaʻa viscosity:hydroxypropyl methylcelluloseHoʻohana nui ʻia ʻo HPMC 20000-40000 no ka tile adhesive, caulking agent, anti-cracking mortar, thermal insulation bonding mortar, etc.

Ke kumu: maikaʻi ka hana, emi ka wai hoʻohui, kiʻekiʻe mortar compactness.

1. He aha ke kumu 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 lāʻau lapaʻau e like me ke kumu. I kēia manawa, ʻo ka hapa nui o nā huahana home ka pae kūkulu. I ka papa hana, he nui loa ka nui o 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. He nui nā ʻano o ka 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. Puka koke nā huahana ʻano ʻano koke i ka wai anuanu a nalowale i loko o ka wai. I kēia manawa, ʻaʻohe viscosity 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, piʻi mālie ka viscosity o ka wai, e hana ana i kahi colloid viscous transparent. ʻO nā huahana hoʻoheheʻe wela, ke hālāwai 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 (ʻo ka huahana o kā mākou hui he 65 degere Celsius), ʻike mālie ka viscosity a hiki i ka hoʻokumu ʻana i kahi colloid viscous māmā. Hiki ke hoʻohana wale ʻia ke ʻano hoʻoheheʻe wela i ka pauka putty a me ka mortar. I loko o ke kolu wai a me ka pena, e kū mai ke ʻano clumping a ʻaʻole hiki ke hoʻohana. Loaʻa i ka ʻano koke ka laulā o nā noi. Hiki ke hoʻohana ʻia i loko o ka pauka putty a me ka mortar, a me ka wai 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 i hoʻoheheʻe ʻia ka HPMC i ka wai wela, hiki ke hoʻopuehu like ʻia ka HPMC i loko o ka wai wela i ka wā mua, a laila e hoʻoheheʻe koke ʻia ke hoʻomaloʻo. ʻElua mau ʻano maʻamau i wehewehe ʻia penei:

1) E hoʻokomo i ka wai wela i makemake ʻia i loko o ka ipu a hoʻomehana iā ia ma kahi o 70 ° C. Hoʻohui mālie ʻia ka hydroxypropyl methylcellulose me ka hoʻoulu lohi ʻana, i ka mua ua lana ka HPMC ma luna o ka ʻili o ka wai, a laila hana mālie i kahi slurry, i hoʻoluʻu ʻia 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 ipu, a wela iā 70 ° C, e like me ke ʻano o 1), hoʻopuehu HPMC, hoʻomākaukau i ka slurry wai wela; a laila hoʻohui i ke koena o ka wai anuanu i ka wai wela I loko o ka slurry, ua maʻalili ka hui ʻana ma hope o ka hoʻoulu ʻana.

ʻO ke ʻano o ka hui ʻana o ka pauda: E hui pū i ka pauka HPMC me ka nui o nā mea pauda ʻē aʻe, e hui pono me ka mea hui pū, a laila e hoʻohui i ka wai e hoʻoheheʻe ʻia, a laila hiki ke hoʻoheheʻe ʻia ka HPMC i kēia manawa me ka ʻole o ka hui ʻana, no ka mea he ʻuʻuku wale ka HPMC i kēlā me kēia. kihi liʻiliʻi liʻiliʻi. E hoʻoheheʻe koke ʻia ka pauka i ka pili ʻana me ka wai. ——Ke hoʻohana ʻia nei kēia ʻano e nā mea hana i ka pauka putty a me ka motar. [Hoʻohana ʻia ka Hydroxypropyl methylcellulose (HPMC) ma ke ʻano he mānoanoa a me ka mea hoʻopaʻa wai i loko o 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 hiki i ka keʻokeʻo ke hoʻoholo inā he maʻalahi ka HPMC e hoʻohana, a inā hoʻohui ʻia kahi mea hoʻomālamalama i ke kaʻina hana, 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, a ʻoi aku ka liʻiliʻi o 120 mesh. ʻO ka hapa nui o ka HPMC i hana ʻia ma Hebei he 80 mesh. ʻOi aku ka maikaʻi o ka maikaʻi. (3) Ka lawe ʻana: E hoʻokomo i ka hydroxypropyl methylcellulose (HPMC) i loko o ka wai e hana i kahi colloid maopopo, a nānā i kāna transmittance. ʻO ke kiʻekiʻe o ka transmittance, ʻoi aku ka maikaʻi, e hōʻike ana he liʻiliʻi nā mea hiki ʻole ke hoʻoheheʻe ʻia i loko. Maikaʻi ka permeability o ka reactor vertical, a ʻoi aku ka maikaʻi o ka reactor horizontal, akā ʻaʻole hiki ke ʻōlelo ʻia ʻoi aku ka maikaʻi o ka reactor vertical ma mua o ka reactor horizontal, a he nui nā kumu e hoʻoholo ai i ka maikaʻi o ka huahana. (4) Kaumaha kikoʻī: ʻoi aku ka nui o ka ʻumekaumaha kikoʻī, ʻoi aku ka ʻoi aku ka maikaʻi. Nui ka ʻumekaumaha kikoʻī, maʻamau no ka mea kiʻekiʻe ka ʻike hydroxypropyl i loko, a kiʻekiʻe ka ʻike hydroxypropyl, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai.

5. Ka nui o ka hydroxypropyl methylcellulose (HPMC) i ka pauka putty?

——Pane: ʻO ka nui o ka HPMC i hoʻohana ʻia i nā noi kūpono e like me ke aniau, ka mahana, ka maikaʻi calcium lehu kūloko, ke ʻano o ka pauka putty a me ka "maikaʻi i makemake ʻia e nā mea kūʻai". Ma ka ʻōlelo maʻamau, 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 pauda putty ma Guizhou he 5 kg i ke kauwela a me 4.5 kg i ka hoʻoilo;

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

——Pane: He 100,000 yuan ka nui o ka pauda Putty, a ua oi aku ke koi o ka paakai, a ua maalahi ke hoohana ia ma 150,000 yuan. Eia kekahi, ʻo ka hana koʻikoʻi o ka HPMC ʻo ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I ka pauka putty, ʻoiai ka maikaʻi o ka paʻa ʻana o ka wai a haʻahaʻa ka viscosity (70,000-80,000), hiki nō hoʻi. ʻOiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka viscosity, a 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 mālama ʻana i ka wai.

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

——Pane: Hydroxypropyl content and viscosity, ka hapanui o nā mea hoʻohana e mālama i kēia mau hōʻailona ʻelua. ʻOi aku ka nui o ka hydroxypropyl content, ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. ʻO ka viscosity kiʻekiʻe, ka paʻa ʻana o ka wai, ʻoi aku ka maikaʻi (ma mua o ka paʻa ʻole), 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, methyl chloride, propylene oxide, nā mea waiwai ʻē aʻe e pili ana i ka flake alkali, acid, toluene, isopropanol, etc.

9. He aha ke kuleana nui o ka HPMC i ka hoʻohana ʻana i ka pauka putty, a aia kekahi kemika?

——Pane: He ʻekolu mau hana o ka HPMC o ka mānoanoa, ka mālama ʻana i ka wai a me ke kūkulu ʻana i ka pauda putty. Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻokuʻu, e mālama i ka hoʻonā ʻano like ʻole a paʻa, a kūʻē i ka sagging. Paʻa wai: E hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka hopena o ka calcium lehu ma lalo o ka hana o ka wai. Hana: He hopena lubricating ka 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 ʻia ma ka paia he hopena kemika. Ma muli o ka hoʻokumu ʻia ʻana o nā mea hou, e lawe i ka pauda putty ma ka paia mai ka paia, e wili a lilo i pauda, ​​a hoʻohana hou. ʻAʻole ia e hana, no ka mea, ua hoʻokumu ʻia nā mea hou (calcium carbonate). ) i luna. ʻO nā mea nui o ka pauka calcium lehu: he hui ʻana o Ca(OH)2, CaO a me kahi liʻiliʻi o CaCO3, CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O Ash calcium i ka wai a me ka ea Ma lalo o ka hana a CO2, hoʻokumu ʻia ka calcium carbonate, ʻoiai ʻo HPMC e mālama wale i ka wai a kōkua i ka hopena maikaʻi o ka calcium lehu, a ʻaʻole i komo i loko o kekahi hopena ponoʻī.

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

- Pane: Ma ka ʻōlelo a ka poʻe kamaʻāina, ʻaʻole ionize nā ion i ka wai. ʻO ka Ionization e pili ana i ke kaʻina hana e hoʻokaʻawale ʻia ai kahi electrolyte i loko o nā ion i hoʻopaʻa ʻia i loko o kahi mea hoʻoheheʻe kūikawā (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 ka wai a hoʻoheheʻe ʻia e hana i nā ion sodium neʻe manuahi (Na+) i hoʻouka maikaʻi ʻia a me nā ion chloride (Cl) i hoʻoili ʻole ʻia. 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 o nā mole.
