ʻO EipponCell MHEC LH 640M, ʻo ia ka methyl hydroxyethyl cellulose, i hoʻohana mau ʻia i loko o ka hamo maloʻo.Eia ka wehewehe ʻana i nā mea nui i ʻōlelo ʻia ma ka paukū.
Paʻa wai maikaʻi: Mālama ʻo MHEC i ka paʻa ʻana o ka wai i ka mortar, e pale ana i nā pilikia e like me ke one, ka pauka, a me ka hoʻohaʻahaʻa ikaika ma muli o ka nele o ka wai a me ka hydration sima ʻole.Hoʻonui ia i ka kūlike, ka hana, a me ka paʻakikī o ka huahana.Ke piʻi aʻe ka nui o ka MHEC i hoʻohui ʻia, piʻi pū ka hoʻoulu ʻana a me ka viscosity frown o ka mortar.
Mea hoʻoheheʻe ea: Hiki i ka MHEC ke hana ma ke ʻano he mea hoʻopili ea.Loaʻa ka ʻike ea kiʻekiʻe loa i ka mortar ke loaʻa ka nui o ka MHEC he 0.5%.Eia nō naʻe, ke ʻoi aku ka nui o ka nui ma mua o 0.5%, e emi mālie ka ʻike o ka ea, e alakaʻi ana i ka hoʻemi ʻana i ka ikaika flexural a me ka ikaika compressive.
ʻOi aku ka maikaʻi o ka hana: ʻO ka hoʻohui ʻana o MHEC e hoʻomaʻamaʻa i ka hoʻohana ʻana i ka mīkini paʻa lahilahi a me ka hamo plastering.Hoʻopaneʻe ʻo MHEC i ka hoʻoheheʻe ʻana o nā ʻāpana mortar, a he koʻikoʻi ko ke degere o ka hoʻololi ʻana (DS) i kēia kaʻina hydration lohi.ʻOi aku ka nui o ka hopena o ka methoxyl content i ka hoʻopaneʻe ʻana i ka hydration ma mua o ko ka hydroxyethyl content.
He mea nui e hoʻomaopopo i ka cellulose ether ka hopena pālua i ka hana mortar.ʻO kona kūpono e pili ana i ka hoʻohana kūpono;hiki i ka hoʻohana pono ʻole ke loaʻa nā hopena maikaʻi ʻole.Hoʻopili ʻia ka hana ʻana o ka mortar maloʻo e nā mea e like me ke kūlike o ka cellulose ether a me ka nui a me ke kaʻina o ka hoʻohui.Ma nā hana kūpono, hiki ke kohoʻia kahiʻano cellulose ether, aiʻole nāʻano likeʻole e hiki ke hoʻohana i ka hui.
