He wahi koʻikoʻi ka EipponCell® HEMC LH 6150M hydroxyethyl methyl cellulose i waena o nā mea hoʻohui cellulose ether i loko o ke aupuni o ka mortar pauka maloʻo.Hoʻopuka kēia hydroxyethyl methylcellulose i kahi plethora o nā hana i ka wā i hoʻohui ʻia i loko o nā hoʻoheheʻe ʻia.ʻO kāna hana koʻikoʻi i ka mortar sima aia i ka paʻa ʻana o ka wai a me ka mānoanoa, nā mea koʻikoʻi e hoʻohālikelike ai i kāna pono.
Ma waho aʻe o kāna mau kuleana koʻikoʻi, ʻo ka pilina o hydroxyethyl methyl cellulose me ka matrix cement e hāʻawi iā ia i nā mea kōkua.Hoʻopili kēia i ka hoʻomaʻamaʻa ʻana i ka ea, ka hoʻopaneʻe ʻana i nā manawa hoʻonohonoho, a me ka hoʻonui ʻana i ka ikaika paʻa tensile, e hāʻawi ana i kahi hopena piha i ka hana mortar.
Puka mai ka paʻa ʻana o ka wai ma ke ʻano he pōhaku kihi o ka hopena o ka HEMC i ka palaki.Loaʻa kēia mea hoʻohui cellulose ether i ka hoʻohana ʻana ma waena o kahi kikoʻī o nā huahana mortar ma muli o kona akamai i ka mālama ʻana i ka wai.ʻO ke kiʻekiʻe o ka paʻa ʻana o ka wai i loaʻa e HEMC ua pili paʻa i nā mea e like me ka viscosity, degere o ka hoʻololi ʻana, a me ka nui o nā ʻāpana, e hui pū ana i kona pono.
Ke hoʻohana ʻia ma ke ʻano he mānoanoa, pili pono ka ikaika mānoanoa o ka hydroxyethyl methyl cellulose i nā ʻāpana e like me ke kiʻekiʻe o ka hoʻololi ʻana, ka nui o ka ʻāpana, ka viscosity, a me ke degere o ka hoʻololi.ʻO ka ʻōlelo ākea, ʻoi aku ka kiʻekiʻe o ke kiʻekiʻe o ka hoʻololi ʻana a me ka viscosity o ka cellulose ether, i hui pū ʻia me nā ʻāpana liʻiliʻi liʻiliʻi, ʻoi aku ka nui o ka hopena o ka mānoanoa.
