Ke kuleana o ka hydroxypropyl methylcellulose i loko o ka putty

Mai ka mānoanoa, ka paʻa ʻana o ka wai a me ke kūkulu ʻana o ʻekolu mau hana.

Mānoanoa: Hiki ke hoʻomānoanoa ʻia ka Cellulose e hoʻokuʻu, e mālama i ka hopena like a kūlike, a pale aku i ka sagging. Paʻa wai: E hoʻomaloʻo mālie i ka pauka putty, a kōkua i ka hana o ka lehu calcium ma lalo o ka hana a ka wai. Kūkulu ʻana: Loaʻa i ka Cellulose kahi hopena lubricating, hiki ke hana maikaʻi i ka pauka putty. ʻAʻole komo ka Hydroxypropyl methylcellulose i kekahi hopena kemika a pāʻani wale i kahi hana kōkua. Hoʻohui ʻia ka pauka Putty me ka wai e hoʻohui i ka paia, he hopena kemika ia, no ka mea, aia ke kūkulu ʻia ʻana o kahi mea hou calcium carbonate. ʻO nā mea nui o ka pauka lehu calcium: kahi hui ʻana o ka calcium hydroxide Ca(OH)2, calcium oxide CaO a me kahi liʻiliʻi o ka calcium carbonate CaCO3. Hoʻokumu ka lehu calcium 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 hana maikaʻi o ka lehu calcium, ʻaʻole ia e komo i kekahi hopena.

Hoʻopili mua mākou i nā kumu no 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. I ka hana maoli ʻana, i mea e wikiwiki ai ka palaho ʻana, hoʻonui pinepine ʻia ka mahana calcination i 1000-1100 °C. Ma muli o ka nui o nā mea maka limestone a i ʻole ka hoʻolaha like ʻole o ka mahana i loko o ka umu i ka wā o ka calcination, loaʻa pinepine i ka lime ka lime underfireed a me ka lime overfired. ʻAʻole i palaho loa ka calcium carbonate i loko o ka lime underfire, a nele i ka ikaika cohesive i ka wā e hoʻohana ai, ʻaʻole hiki ke hāʻawi i ka ikaika cohesive lawa i ka putty, e hopena ana i ka wehe ʻana o ka pauka i hoʻokumu ʻia e ka paʻakikī a me ka ikaika o ka putty.

2. ʻO ke kiʻekiʻe o ka nui o ka calcium hydroxide i loko o ka pauka calcium lehu, ʻoi aku ka maikaʻi o ka paʻakikī o ka putty i hana ʻia. I ka ʻaoʻao ʻē aʻe, ʻo ka haʻahaʻa o ka nui 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 ana i ka pilikia o ka wehe ʻana i ka pauka a me ka wehe ʻana i ka pauka.

3. Hoʻohuihui ʻia ka pauka kalipuna lehu me ka nui o ka pauka kalipuna kaumaha, ʻo ia hoʻi ke kumu o ka haʻahaʻa loa o ka pauka kalipuna lehu e hāʻawi i ka paʻakikī a me ka ikaika i ka putty, e hāʻule ai ka pauka o ka putty. ʻO ka hana nui o ka pauka putty, ʻo ia ka mālama ʻana i ka wai, e hāʻawi i ka wai lawa no ka paʻakikī ʻana o ka pauka kalipuna lehu, a e hōʻoia i ka hopena paʻakikī lawa. Inā he pilikia me ke ʻano o ka hydroxypropyl methylcellulose a i ʻole ka haʻahaʻa o ka ʻike kūpono, ʻaʻole hiki ke hāʻawi ʻia ka makū lawa, ʻo ia hoʻi ka lawa ʻole o ka paʻakikī a e hāʻule ai ka pauka o ka putty.

Hiki ke ʻike ʻia mai luna mai he haʻahaʻa loa ke ʻano o ka hydroxypropyl methylcellulose a ʻaʻole hiki ke hoʻokō i kahi hopena, a e hāʻule ka pauka putty. ʻO ke kumu nui, ʻo ia ka calcium kaumaha hina.
