Fahimtar MHEC
Menene MHEC?
Methyl Hydroxyethyl Cellulose (MHEC) wani sinadari ne mai sinadarin cellulose wanda ba ionic ba wanda aka samo daga cellulose na halitta, wanda aka saba samu daga auduga mai tsafta ko kuma ɓangaren itacen.
Ta hanyar tsarin etherification mai sarrafawa, ana gyaggyara cellulose ta hanyar sinadarai ta hanyar gabatar da:
- Rukunin Methyl
- Rukunin Hydroxyethyl
Waɗannan gyare-gyaren suna canza cellulose mara narkewa zuwa polymer mai narkewa cikin ruwa tare da kyawawan halaye na kauri da riƙe ruwa.
MHEC tana cikin iyali ɗaya kamar:
- Cellulose na Hydroxypropyl Methyl (HPMC)
- Hadin Hydroxyethyl Cellulose (HEC)
- Methyl Cellulose (MC)
- Carboxymethyl cellulose (CMC)
Daga cikin waɗannan ƙwayoyin cellulose ethers, MHEC ta shahara musamman a aikace-aikacen gini saboda ingantaccen riƙe ruwa da kuma dacewarsa mai kyau da tsarin siminti da gypsum.
