Hoʻohana ʻia ka HPMC i ka putty pā

1. He aha nā hōʻailona ʻenehana nui o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO ka HPMC Hydroxypropyl content a me ka viscosity, ka hapa nui o nā mea hoʻohana e hopohopo e pili ana i kēia mau hōʻailona ʻelua. ʻOi aku ka maikaʻi o ka mālama ʻana i ka wai no ka poʻe me ka hydroxypropyl kiʻekiʻe. ʻO ka viscosity kiʻekiʻe, ka paʻa ʻana o ka wai, ʻoi aku ka maikaʻi (ma mua o ka paʻa) ʻoi aku ka maikaʻi, a me ka viscosity kiʻekiʻe, ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka mortar sima.

2. He aha ka hana nui o ka hoʻohana ʻana o HPMC i ka putty pā?

I loko o ka pā putty, HPMC i ekolu hana: mānoanoa, ka wai paʻa a me ka hana.

Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻopaneʻe a mālama i ka ʻaʻahu hoʻonā, a me ka pale ʻana i ka sagging. Ka paʻa wai: e hoʻomaloʻo mālie i ka pā, a kōkua i ka calcium hina e hana ma lalo o ka hana o ka wai. Hana ʻia: He hopena lubricating ka Cellulose, hiki ke hana i ka putty pā i ka hana maikaʻi.

3. Pili ka kulu o ka putty pā i HPMC?

ʻO ka hāʻule o ka putty pā e pili nui 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 ratio o CaO a me Ca(OH)2 i loko o ka calcium lehu, e lilo ia i ka pauka. Inā pili ia me ka HPMC, a laila, ʻo ka paʻa ʻana o ka wai maikaʻi ʻole o ka HPMC, e hāʻule pū ka pauka.

4. Ehia ka nui o ka hydroxypropyl methyl cellulose (HPMC) i loko o ka putty pā?

ʻO ka nui o ka HPMC i hoʻohana ʻia i nā noi maoli ʻokoʻa ma muli o ke aniau, ka mahana, ka maikaʻi o ka calcium lehu kūloko, ke ʻano o ka putty pā, 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 putty pā o Beijing ka nui o 5 kg; ʻO Guizhou ka nui o 5 kg i ke kauwela a me 4.5 kg i ka hoʻoilo; He ʻuʻuku liʻiliʻi ʻo Yunnan, maʻamau 3 kg a 4 kg a pēlā aku.

5. He aha ka viscosity kūpono o ka hydroxypropyl methyl cellulose (HPMC)?

ʻO ka putty pā he 100,000 maʻamau, akā ʻoi aku ka koi o ka mortar, a he 150,000 ka hana. 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 pā putty, i ka lōʻihi o ka paʻa ʻana o ka wai, ʻoi aku ka haʻahaʻa o ka viscosity (70-80,000), hiki nō hoʻi, ʻoiaʻiʻo, ʻoi aku ka kiʻekiʻe o ka viscosity, a ʻoi aku ka maikaʻi o ka paʻa wai pili. 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 hoʻohana ʻana i ka putty pā: ʻoi aku ka haʻahaʻa, ʻo ka viscosity he 100,000, lawa ia, ʻo ka mea nui ka mālama ʻana i ka wai. Ka hoʻohanaʻana i ka mortar: nā koi kiʻekiʻe, ka viscosity kiʻekiʻe,ʻoi aku ka maikaʻi ma mua o 150,000, ka hoʻohanaʻana i ke kāpili: nā huahana wikiwiki, ka viscosity kiʻekiʻe.

7. ʻO ka hoʻohana ʻana o HPMC i ka putty pā, he aha ka mea e hoʻopuka ai ka putty pā i nā ʻōpū?

Hoʻokani ʻo HPMC i ʻekolu hana i ka putty pā: mānoanoa, paʻa wai a me ke kūkulu ʻana. Mai komo i kekahi pane. ʻO nā kumu o nā ʻōpala:

(1) Nui loa ka wai i hookomoia.

(2) ʻAʻole maloʻo ka papa lalo, a ua ʻoki ʻia kahi papa ʻē aʻe ma luna o ia mea, a he maʻalahi hoʻi e hoʻohuhū.
