ʻO EipponCell® HEMC LH 6100M hydroxyethyl methyl cellulose (HEMC) ke kū nei ma ke ʻano he mea koʻikoʻi i ka hoʻokumu ʻana i ka mīkini hoʻoheheʻe mīkini.ʻO kāna mau hana koʻikoʻi e hoʻopili i kahi ʻano mānoanoa kupaianaha, i hui pū ʻia me kahi mākaukau kūikawā no ka mālama ʻana i ka wai.Eia hou, lawe ia i ka reins i ka hoʻololi ʻana i ka density a me ka rheology o ka mortar.Eia naʻe, ʻaʻole me ka ʻole o kona mau palena.ʻO ka mea nui, hoʻolauna ʻo HEMC i kahi hopena ea-entrainment, e alakaʻi ana i ka hoʻokumu ʻana o nā pores o loko a me nā hemahema.ʻO ka mea minamina, hoʻopau kēia hopena i nā waiwai mechanical o ka mortar, e hōʻemi nui ana.
Me ka hoʻokomo ʻana o ka cellulose ether i loko o ka mortar, wehe ʻia kahi hoʻololi ikaika.Hoʻoulu kēia hoʻohui i ka hoʻonui ʻana o nā hale polymer maʻalahi i loko o nā pores o ka mortar.ʻOiai ke hāʻawi nei kēia mau polymers maʻalahi i nā pōmaikaʻi, ua pōkole kā lākou kuleana ma ke ʻano he kākoʻo paʻa ma lalo o ke kaomi.No laila, ʻo kēia hoʻopili paʻakikī e hoʻemi i ka ikaika o ka mortar i ka ikaika flexural a me ka compressive.
