HPMC a me ka pauka putty

1. He aha ka hana nui o ka hoʻohana ʻana o HPMC i ka pauka putty?Aia kekahi hopena 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 liʻiliʻi o CaCO3, CaO H2O=Ca(OH)2 —Ca(OH)2 CO2=CaCO3↓ H2O ʻO ke kuleana o ka calcium lehu. i CO2 i ka wai a me ka ea Ma lalo o kēia kūlana, hoʻokumu ʻia ka calcium carbonate, ʻoiai ʻo HPMC wale nō ka mālama ʻana i ka wai, e kōkua ana i ka hopena maikaʻi o ka calcium lehu, a ʻaʻole i komo i kekahi ʻano hana ponoʻī.

2. He aha ka nui o ka HPMC i hoʻohui ʻia i ka pauka putty?

——Pane: ʻOkoʻa ka nui o ka HPMC i hoʻohana ʻia i nā noi 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 i makemake ʻia e nā mea kūʻai".ʻO ka maʻamau, ma waena o 4 kg a 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;liʻiliʻi ka nui o ka putty ma Yunnan, maʻamau 3 kg a 4 kg, etc.

3. He aha ka viscosity kūpono o HPMC i ka pauka putty?

——Pane: ʻO ka mea maʻamau, ua lawa ka 100,000 yuan no ka pauda putty, a ʻoi aku ka kiʻekiʻe o nā koi no ka pahū, a ʻo 150,000 yuan ke koi ʻia 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.

4. No ke aha e hū ai ka pauda putty?

——Pane: Phenomenon: hana ʻia nā ʻōhū i ka wā o ke kaʻina hana a ma hope o kekahi manawa, pohu ka ʻili o ka putty.

kumu:

1. He oolea loa ke kumu a me ka wikiwiki o ka hamo;

2. He mānoanoa loa ka papa putty i loko o ka hale hoʻokahi, ʻoi aku ka nui ma mua o 2.0mm;

3. He kiʻekiʻe loa ka mākū o ka ʻuʻu, a ʻoi aku ka nui a i ʻole ka liʻiliʻi.

4. Ma hope o kekahi manawa o ke kūkulu ʻia ʻana, ʻo ka ʻūhā a me ka huʻa ʻana ma luna o ka ʻili ke kumu nui ʻia e ka hui ʻole ʻana, ʻoiai ʻo HPMC ka hana i ka mālama ʻana i ka wai, ka mānoanoa a me ka hoʻomaikaʻi ʻana i ka hana i ka pauka putty, a ʻaʻole komo i kekahi pane.

5. He aha ke kumu o ka wehe ʻana i ka pauka o ka pauka putty?

——Pane: E pili ana keia i ka nui a me ka maikai o ka calcium hina.ʻO ka haʻahaʻa o ka calcium hina o ka calcium hina a me ka ratio kūpono ʻole o CaO a me Ca(OH)2 i loko o ka calcium hina e hoʻopau ʻia ka pauka.Ma ka manawa like, pili pū me HPMC.He haʻahaʻa ka nui o ka paʻa ʻana o ka wai, a ʻaʻole lawa ka manawa o ka hydration calcium lehu, kahi e hoʻopau ʻia ai ka pauka.

6. No ke aha i kaumaha ai ka putty i ka ʻōpala?

——Pane: I kēia hihia, ʻoi aku ka kiʻekiʻe o ka viscosity o ka cellulose maʻamau.Hoʻohana kekahi mau mea hana i 200,000 cellulose e hana i ka putty.ʻO ka putty i hana ʻia ma kēia ʻano he viscosity kiʻekiʻe, no laila kaumaha ke kaumaha ke ʻoki.ʻO ka nui o ka pauka putty no nā paia o loko he 3-5 kg, a ʻo ka viscosity he 80,000-100,000.
