Hoʻohana ʻia ka HPMC i ka pauka putty

1. He aha ka viscosity kūpono o HPMC?

——Pane: ʻO ka maʻamau, lawa ka 100,000 yuan no ka pauda putty. ʻOi aku ka kiʻekiʻe o nā koi no ka mortar, a koi ʻia ka 150,000 yuan no ka hoʻohana maʻalahi. Eia kekahi, ʻo ka hana nui o ka HPMC ʻo ka mālama ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka pauka putty, ʻoiai he maikaʻi 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, ʻoi aku ka maikaʻi o ka paʻa wai pili. Ke ʻoi aku ka viscosity ma mua o 100,000, e hoʻopilikia ka viscosity i ka paʻa wai. ʻAʻole nui hou.

2. He aha nā hōʻailona ʻenehana nui oHPMC?

——Pane: Hydroxypropyl content and viscosity, ka hapanui o nā mea hoʻohana e hopohopo nei i kēia mau hōʻailona ʻelua. ʻOi aku ka maikaʻi o ka mālama ʻana i ka wai i ka poʻe me ka hydroxypropyl kiʻekiʻe. ʻO ka mea nona ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai, ma ke ʻano (ʻaʻole loa), a ʻoi aku ka maikaʻi o ka mea nona ka viscosity kiʻekiʻe i loko o ka momi sima.

3. He aha ka hana nui o ka hoʻohana ʻana i ka HPMC i ka pauka putty, a hiki ke hana kemika?

——Pane: I loko o ka pauda putty, hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana. Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻopaneʻe a mālama i ka hoʻonā ʻaʻahu i luna a i lalo, a pale aku i ka haʻalulu. Ka paʻa ʻana o ka wai: e hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka calcium lehu e hana ma lalo o ka hana o ka wai. Hana: He hopena lubricating ka Cellulose, hiki ke hana i ka pauka putty i ke kūkulu maikaʻi. ʻAʻole komo ʻo HPMC i nā hopena kemika, akā 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, no ka mea, ua hana ʻia nā mea hou. Inā wehe ʻoe i ka pauda putty ma ka paia mai ka paia, wili a lilo i pauda, ​​a hoʻohana hou, ʻaʻole ia e hana no ka mea ua hana ʻia nā mea hou (calcium carbonate). ) kekahi. ʻO nā mea nui o ka pauka calcium lehu: he hui ʻana o Ca(OH)2, CaO a me kahi wahi liʻiliʻi o CaCO3, CaO+H2O=Ca(OH)2 —Ca(OH)2+CO2=CaCO3↓+H2O Aia ka calcium lehu i loko o ka wai a me ka ea Ma lalo o ka hana a CO2, hana ʻia ka calcium carbonate, ʻoiai ʻo HPMC wale nō ka mālama ʻana i ka wai, kōkua i ka hana maikaʻi o ka calcium.

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

——Pane: Ma ka olelo a ke kanaka kamaaina, he mau mea ole ka ion i ka wai. ʻO ka Ionization e pili ana i ke kaʻina hana i hoʻokaʻawale ʻia kahi electrolyte i nā ion i hoʻopaʻa ʻia e hiki ke neʻe manuahi i loko o kahi mea hoʻoheheʻe kūikawā (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 hoʻoheheʻe ʻia e hana i nā ion sodium hiki ke hoʻoneʻe ʻia (Na+) i hoʻopaʻa maikaʻi ʻia a me nā ion chloride (Cl) i hoʻoili ʻole ʻia. ʻO ia hoʻi, ke hoʻokomo ʻia ka HPMC i loko o ka wai, ʻaʻole ia e hoʻokaʻawale i loko o nā ion i kau ʻia, akā aia ma ke ʻano o nā mole.

5. Aia kekahi pilina ma waena o ka kulu o ka pauda putty a me HPMC?

——Pane: Ua pili ka pauda o ka pauda putty i ka maikai o ka calcium lehu, a he mea li'ili'i ka pili ana i ka HPMC. ʻO ka haʻahaʻa o ka calcium haʻahaʻa o ka calcium hina a me ka ratio kūpono ʻole o CaO a me Ca(OH)2 i loko o ka calcium hina e lilo ai ka pauda. Inā he mea pili ia me HPMC, a laila inā ʻilihune ka paʻa ʻana o ka wai o ka HPMC, e lilo nō ia i ka pauda.

6. Pehea e koho ai i kahi kūponoHPMCno nā kumu like ʻole?

——Pane: ʻO ka hoʻohana ʻana i ka pauda putty: ʻoi aku ka haʻahaʻa o nā koi, a ʻo ka viscosity he 100,000, ʻo ia ka lawa. ʻO ka mea nui e mālama pono i ka wai. Ka hoʻohana ʻana i ka mortar: nā koi kiʻekiʻe, kiʻekiʻe viscosity, 150,000 ʻoi aku ka maikaʻi. Ka hoʻohana ʻana i ke kāpili: pono nā huahana koke me ka viscosity kiʻekiʻe.
