Kuphatikizika kwa EipponCell® HEMC LH 620M Cellulose ether mumatope kumapangitsa kuti pakhale ntchito ziwiri zosunga madzi komanso kukhuthala.Ngakhale pa mlingo wochepa wa 0.2%, umachepetsa kwambiri zovuta za delamination mumatope opaka pulasitala omwe amapangidwa ndi konkriti wopangidwa ndi mpweya, nthawi yomweyo kumapangitsa kuti madzi asamasungidwe bwino, motero akuwonetsa kugwira ntchito modabwitsa pankhaniyi.
Kuphatikiza apo, HEMC imawonetsa chibadwa chothandizira mpweya, zomwe zimapangitsa kuti matope azigwira bwino ntchito.Zodziwika bwino, zimathandizanso kuchepetsa kuuma kwa matope, ndipo izi zimawonekera kwambiri ndi kuchuluka kwa HEMC.
Pakuwonjezera kwa HEMC ku matope osakaniza, kuchepetsedwa kwa m'mphepete mwa mphamvu zowonongeka kumawonedwa, pamene pali kuchepa kwakukulu kwa mphamvu yopondereza.Kupindika kwa chiŵerengero chopindika kumawonetsa njira yopita kumtunda, kusonyeza kuti HEMC supplementation imawonjezera kulimba kwa matope.
Chochititsa chidwi kwambiri ndi HEMC ndi mphamvu yake yosungira madzi.Katunduyu amagwira ntchito ngati chotchinga kuti asamwe madzi mwachangu ndi konkriti yolumikizidwa ndi mpweya popaka matope.Chotsatira chake, imaonetsetsa kuti simenti imasungunuka bwino mumatope, zomwe zimapangitsa kuti pakhale matope osakanikirana ndi konkire yopangidwa ndi mpweya, motero amakweza mphamvu zomangira kumagulu apamwamba.
