Putty pauka-hydroxypropyl methylcellulose

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

ʻO ka hydroxypropyl content a me ka viscosity, hopohopo ka hapa nui o nā mea hoʻohana 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.

2. He aha ka hana nui o ka noi o HPMC i ka pauka putty?

I loko o ka pauka putty, ʻekolu mau hana o ka HPMC 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.

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

ʻO ka lilo o ka pauka o ka pauka putty e pili nui i ka maikaʻi o ka calcium lehu, a ʻaʻohe mea liʻiliʻi me HPMC.ʻAʻole kūpono ka ʻike calcium o ka calcium hina a me ka ratio o CaO a me Ca(OH)2 i ka calcium hina, kahi e lilo ai ka pauda.Inā pili ia me ka HPMC, a laila, ʻo ka paʻa ʻana o ka wai maikaʻi ʻole o ka HPMC e lilo pū ai ka pauda.

4. He aha ka nui o ka hydroxypropyl methylcellulose (HPMC) i ka pauka putty?

ʻO ka nui o ka HPMC i hoʻohana ʻia i nā noi kūpono ʻokoʻa 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'.

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

ʻO ka maʻamau, ua lawa ka 100,000 yuan o ka pauka putty, a 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 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, ʻaʻohe hopena o ka viscosity i ka mālama ʻana i ka wai.nui.

6. Pehea e koho ai i ka hydroxypropyl methylcellulose (HPMC) kūpono no nā kumu like ʻole?

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

7. ʻO ka hoʻohana ʻana o HPMC i ka pauka putty, he aha ke kumu o nā ʻōhū i loko o ka pauka putty?

I loko o ka pauka putty, hoʻokani ʻo HPMC i ʻekolu hana o ka mānoanoa, paʻa wai a me ke kūkulu ʻana.Mai komo i kekahi hopena.Nā kumu o nā ʻōpū:

1. E kau i ka wai nui.

2. Ke maloʻo ʻole ka papa lalo, ʻoki ʻia kahi papa ʻē aʻe ma luna, a maʻalahi ka huʻa.
