KimaCell® HEMC MH40M, oo ah nooc ka mid ah etherka cellulose, waxa uu u adeegaa sidii wax ka beddelka viscosity ee caadi ahaan loo shaqeeyo ee shubka ah.Waxay ka helaysaa codsi ballaaran oo la taaban karo iyo walxaha qashinka ah ee is-xakameynaya.Waxyaabaha lagu daro waxay kor u qaadaysaa isku-xidhnaanta walxaha sibidhka ku salaysan iyo isku-dhafka qaab-dhismeedkooda adag.Saamaynta HEMC sida wax ka beddelka viscosity-ka ee sifooyinka cusub, sifooyinka farsamada, iyo qallajinta hoobiyeyaasha ayaa la baaray.Habka ficilka ayaa la baadhay iyadoo lagu salaynayo nuxurka biyaha aan uumi-baxa lahayn iyo qaab dhismeedka daldaloolada.Intaa waxaa dheer, saameynta faa'iidada leh ee wax ka beddelka HEMC ee dabada birta ah ee dhoobada cement cement ayaa la muujiyay.
HEMC waxay si gaar ah kor ugu qaadaa viscosity of hoobiye.Marka la isticmaalo iyada oo lala kaashanayo wakiilka biyaha-yareeya, waxay ku gaadhaysaa dareeraha la kantaroolay gudaha xadka ku habboon waxayna yaraynaysaa heerka dhiigbaxa hoobiye.
Marka maaddada HEMC ay korodho, xoogga isku-buufinta ee muunado hoobiye ah 7 maalmood iyo 28 maalmood waxay muujinaysaa kor u kac bilaw ah oo ay ku xigto hoos u dhac, gaarey meeshii ugu sarreysay marka maaddada HEMC ay gaarto 0.3%.
