ʻO ke kuleana o ka hydroxypropyl methylcellulose i ka putty

Mai ka mānoanoa, ka mālama ʻana i ka wai a me ke kūkulu ʻana i ʻekolu mau hana.

Mānoanoa: Hiki ke mānoanoa ka cellulose e hoʻokuʻu, e mālama i ka hoʻonā ʻano like ʻole a paʻa, a kūʻē i ka sagging. Paʻa wai: E hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka hopena o ka calcium lehu ma lalo o ka hana o ka wai. Hana: He hopena lubricating ka Cellulose, hiki ke hana i ka pauka putty i ka hana maikaʻi. ʻAʻole komo ʻo Hydroxypropyl methylcellulose i kekahi hopena kemika a hoʻokani wale i kahi hana kōkua. Hoʻohui ʻia ka pauka Putty me ka wai e hoʻopaʻa i ka pā, ʻo ia ka hopena kemika, no ka mea, aia ka hana ʻana o kahi mea hou calcium carbonate. ʻO nā mea nui o ka pauka calcium lehu: kahi hui o ka calcium hydroxide Ca(OH)2, calcium oxide CaO a me kahi liʻiliʻi o ka calcium carbonate CaCO3. Hoʻokumu ka calcium lehu i ka calcium carbonate ma lalo o ka hana a CO2 i ka wai a me ka ea, ʻoiai ʻo hydroxypropyl methyl Cellulose e paʻa wale i ka wai a kōkua i ka hopena maikaʻi o ka calcium lehu, ʻaʻole ia e komo i kekahi pane.

Hoʻopili mua mākou i nā kumu o ka hāʻule ʻana o ka pauka o ka putty mai nā mea maka o ka putty: ka pauka calcium lehu, hydroxypropyl methylcellulose, ka pauka calcium kaumaha, ka pauka calcium lehu wai.

1. Ma ka hana maoli, i mea e wikiwiki ai ka decomposition, hoʻonui pinepine ʻia ka mahana calcination i 1000-1100 °C. Ma muli o ka nui o ka limestone maka a i ʻole ka puʻunaue like ʻole o ka wela i ka kiln i ka wā calcination, loaʻa pinepine ka lime i ka lime underfired a me ka lime overfired. ʻAʻole i hoʻopau loa ʻia ka calcium carbonate i loko o ka lime underfire, a ʻaʻole i lawa ka ikaika i ka wā e hoʻohana ai, ʻaʻole hiki ke hāʻawi i ka ikaika cohesive lawa i ka putty, e hopena i ka wehe ʻana i ka pauka ma muli o ka lawa ʻole o ka paʻakikī a me ka ikaika o ka putty.

2. ʻOi aku ka kiʻekiʻe o ka calcium hydroxide i loko o ka pauka calcium lehu, ʻoi aku ka maikaʻi o ka paʻakikī o ka putty i hana ʻia. ʻO ka mea ʻē aʻe, ʻoi aku ka haʻahaʻa o ka calcium hydroxide i loko o ka pauka calcium lehu, ʻoi aku ka ʻino o ka paʻakikī o ka putty ma kahi hana, e hopena ai i ka pilikia o ka wehe ʻana i ka pauka a me ka wehe ʻana i ka pauka.

3. Hoʻohui ʻia ka pauka calcium lehu me ka nui o ka pauka calcium koʻikoʻi, ʻo ia ka mea e haʻahaʻa loa ai ka ʻike o ka pauka calcium lehu e hāʻawi i ka paʻakikī a me ka ikaika i ka putty, e hāʻule ai ka putty i ka pauka. ʻO ka hana nui o ka pauka putty ka mālama ʻana i ka wai, hāʻawi i ka wai kūpono no ka paʻakikī o ka pauka calcium lehu, a e hōʻoia i ka hopena paʻakikī. Inā loaʻa kahi pilikia me ka maikaʻi o ka hydroxypropyl methylcellulose a i ʻole ka haʻahaʻa o ka ʻike kūpono, ʻaʻole hiki ke hāʻawi ʻia i ka makū, ʻo ia ka mea e lawa ʻole ai ka paʻakikī a hoʻokuʻu i ka pauka.

Hiki ke ʻike ʻia mai luna aʻe nei he ʻilihune loa ka maikaʻi o ka hydroxypropyl methylcellulose a ʻaʻole hiki ke hoʻokō i kekahi hopena, a hāʻule ka pauka putty. ʻO ke kumu nui, ʻo ke kalapona kaumaha hina hina.
