Kev koom ua ke ntawm EipponCell® HEMC LH 620M Cellulose ether rau hauv mortar ua rau muaj kev ua haujlwm ntawm ob qho dej tuav thiab ua kom tuab.Txawm tias qhov tsawg kawg nkaus ntawm 0.2%, nws txo qis cov teeb meem delamination nyob rau hauv plastering mortar npaj rau huab cua-entrained pob zeb, concurrently txhim kho tag nrho cov dej tuav peev xwm ntawm lub mortar, yog li qhia tau hais tias zoo kawg li nyob rau hauv no nam.
Tsis tas li ntawd, HEMC nthuav tawm cov txiaj ntsig hauv huab cua-entraining, ua rau txhim kho kev ua haujlwm ntawm cov tshuaj khib nyiab.Tshwj xeeb, nws tseem ua rau muaj kev txo qis hauv lub tshuaj khib nyiab, thiab cov nyhuv no tau tshaj tawm nrog cov kev xav ntau dua.
Raws li qhov sib ntxiv ntawm HEMC rau cov tshuaj khib sib tov, qhov kev txo qis hauv kev ua kom lub zog yog pom, thaum muaj qhov txo qis hauv compressive zog.Txoj kev khoov piv nkhaus nthuav qhia qhov kev nce siab, qhia tias HEMC supplementation txhim khu lub toughness ntawm mortar.
Ib qho tshwj xeeb tseem ceeb ntawm HEMC yog nws cov dej tuav tau zoo.Cov cuab yeej no ua ib qho thaiv tiv thaiv kev nqus dej sai los ntawm cov khoom siv cua hauv cov txheej txheem plastering mortar.Yog li ntawd, nws ua kom tiav cov dej ntawm cov cement nyob rau hauv lub mortar, uas ua rau muaj kev sib xyaw ua ke ntawm cov tshuaj khib thiab cov khoom siv cua-entrained, yog li ua kom muaj zog ntawm kev sib raug zoo mus rau qib siab dua.
