EipponCell MHEC LH 640M, kaas oo ah methyl hydroxyethyl cellulose, ayaa caadi ahaan loo isticmaalaa hoobiye-engegan.Halkan waxaa ah sharraxaadda qodobbada muhiimka ah ee lagu sheegay tuduca:
Biyo-haysasho wanaagsan: MHEC waxay hubisaa in hoobiye-ku haysto biyo ku filan, ka hortagga arrimaha sida ciid-samaynta, budada, iyo dhimista xoogga ee ay keento yaraanta biyaha iyo fuuq-baxa sibidhka oo aan dhammaystirnayn.Waxay wanaajisaa labbiska, shaqaynta, iyo adkaynta alaabta.Marka qadarka MHEC ee lagu daray uu kordho, walbahaarka dhalidda iyo wejiga wejiga ee hoobiye ayaa sidoo kale kordha.
Wakiilka hawo-mareenka: MHEC waxay u shaqayn kartaa sidii wakiilka hawo-hawo.Waxa ugu sarreeya hawada ku jira hoobiye ayaa la gaadhaa marka qaddarka MHEC uu yahay 0.5%.Si kastaba ha ahaatee, marka qadarku dhaafo 0.5%, hawada hawadu waxay si tartiib tartiib ah hoos ugu dhacdaa, taas oo keenaysa hoos u dhaca xoogga dabacsanaanta iyo xoogga cadaadiska.
Awood shaqayneed oo la hagaajiyay: Ku-darka MHEC waxay sahlaysa in si fudud loo isticmaalo hoobiye-lakab khafiif ah iyo malaastaan.MHEC waxay dib u dhigtaa fuuq-baxa qaybo hoobiye ah, iyo heerka beddelka (DS) ayaa kaalin mug leh ka qaata geeddi-socodkan dib-u-dhaca biyaha.Saamaynta maadada methoxyl ee dib u dhigista fuuq-celinta ayaa aad uga muhiimsan tan ka kooban hydroxyethyl.
Waxaa muhiim ah in la ogaado in ether-ka cellulose uu leeyahay saameyn laba geesood ah oo ku saabsan waxqabadka hoobiye.Waxtarkeedu wuxuu ku xiran yahay isticmaalka habboon;Isticmaalka khaldan wuxuu yeelan karaa saameyn xun.Waxqabadka hoobiyeyaasha qallalan ee qallalan waxaa saameeya arrimo ay ka mid yihiin iswaafajinta ether cellulose iyo qadarka iyo isku xigxiga isku-darka.Codsiyada wax ku oolka ah, hal nooc oo ether cellulose ah ayaa la dooran karaa, ama noocyo kala duwan ayaa loo isticmaali karaa isku darka.
