1. He aha nā ʻōkuhi loea nui o ka hydroxypropyl methyl cellulose (HPMC)?
ʻO ka nui o ka HPMC Hydroxypropyl a me ka viscosity, hopohopo ka hapa nui o nā mea hoʻohana e pili ana i kēia mau ʻōkuhi ʻelua. ʻOi aku ka maikaʻi o ka paʻa ʻana o ka wai no ka poʻe me ka nui o ka hydroxypropyl. ʻOi aku ka maikaʻi o ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka paʻa ʻana o ka wai (ma mua o ka paʻa loa), a ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka sima sima.
2. He aha ka hana nui o ka hoʻopili ʻana o HPMC i ka putty paia?
I loko o ka putty pā, ʻekolu mau hana a HPMC: ka mānoanoa, ka paʻa ʻana o ka wai a me ke kūkulu ʻana.
Mānoanoa: Hiki ke hoʻomānoanoa ʻia ka Cellulose e hoʻokuʻu a mālama i ka like o ka hopena, a e pale aku i ka sagging. Paʻa wai: e hoʻomaloʻo mālie i ka putty paia, a kōkua i ka calcium hina e pane ma lalo o ka hana a ka wai. Kūkulu ʻana: He hopena lubricating ko Cellulose, hiki ke hana maikaʻi i ka putty paia.
3. Pili anei ka hāʻule ʻana o ka putty paia i ka HPMC?
ʻO ka hāʻule ʻana o ka putty paia e pili nui ana i ka maikaʻi o ka calcium lehu, akā ʻaʻole i ka HPMC. Inā kūpono ʻole ka nui o ka calcium o ka calcium lehu a me ka lakio o CaO a me Ca(OH)2 i ka calcium lehu, e lilo ana ka pauka. Inā pili ia i ka HPMC, a laila ʻo ka paʻa ʻole o ka wai o HPMC e lilo pū kekahi i mea e hāʻule ai ka pauka.
4. ʻEhia ka nui o ka hydroxypropyl methyl cellulose (HPMC) i loko o ka putty paia?
ʻOkoʻa ka nui o ka HPMC i hoʻohana ʻia i nā noi maoli ma muli o ke aniau, ka mahana, ka maikaʻi o ka calcium lehu kūloko, ke ʻano o ka putty paia, a me ka "maikaʻi e pono ai nā mea kūʻai aku". Ma ke ʻano laulā, ma waena o 4 kg a me 5 kg. No ka laʻana: ʻo ka putty paia Beijing he 5 kg ka nui; ʻO Guizhou he 5 kg ka nui i ke kauwela a me 4.5 kg i ka hoʻoilo; He liʻiliʻi ʻo Yunnan, maʻamau he 3 kg a 4 kg a pēlā aku.
5. He aha ka mānoanoa kūpono o ka hydroxypropyl methyl cellulose (HPMC)?
ʻO ka putty pā maʻamau he 100,000, akā ʻoi aku ka koi o ka mortar, a he 150,000 ka hana. Eia kekahi, ʻo ke kuleana koʻikoʻi o HPMC ka paʻa ʻana i ka wai, a ukali ʻia e ka mānoanoa. I loko o ka putty pā, inā maikaʻi ka paʻa ʻana o ka wai, haʻahaʻa ka viscosity (70-80,000), 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, ʻaʻohe hopena o ka viscosity i ka paʻa ʻana o ka wai.
6. Pehea e koho ai i ka hydroxypropyl methylcellulose (HPMC) kūpono no nā kumu like ʻole?
ʻO ka hoʻopili ʻana o ka putty pā: ʻoi aku ka haʻahaʻa o ke koi, ʻo ka viscosity he 100,000, ua lawa ia, ʻo ka mea nui ka mālama ʻana i ka wai. Hoʻopili ʻana o ka mortar: nā koi kiʻekiʻe, viscosity kiʻekiʻe, ʻoi aku ka maikaʻi ma mua o 150,000, hoʻopili ʻana o ke kāpili: nā huahana hoʻoheheʻe wikiwiki, viscosity kiʻekiʻe.
7. ʻO ka hoʻopili ʻana o HPMC i ka putty paia, he aha ke kumu o ka putty paia e hana ai i nā pehu?
ʻEkolu kuleana o HPMC i ka putty paia: ka mānoanoa, ka paʻa ʻana o ka wai a me ke kūkulu ʻana. Mai komo i kekahi hopena. Nā kumu no nā pehu:
(1) Nui loa ka wai i hoʻokomo ʻia.
(2) ʻAʻole maloʻo ka papa lalo, a ua ʻānai ʻia kekahi papa ʻē aʻe ma luna, kahi mea maʻalahi hoʻi e huʻa.
