Hydroxyethyl Methyl Cellulose (MHEC) jẹ awọn ethers nonionic cellulose tiotuka omi, eyiti a funni bi erupẹ ti nṣan ọfẹ tabi ni cellulose fọọmu granular.
Hydroxyethyl Methyl Cellulose (MHEC) ti wa ni ṣe lati gíga funfun owu-cellulose nipa lenu ti etherification labẹ ipilẹ awọn ipo lai eyikeyi ara ti eranko, sanra ati awọn miiran bioactive constituents.MHEC han lati wa ni funfun lulú ati ki o jẹ odorless ati ki o lenu.O jẹ ifihan nipasẹ hygroscopicity ati pe ko ṣee ṣe tiotuka ninu omi gbona, acetone, ethanol ati toluene.Ninu omi tutu MHEC yoo gbin sinu ojutu colloidal ati pe o jẹ solybility ko ni ipa nipasẹ iye PH. Iru si methyl cellulose nigba ti a fi kun si awọn ẹgbẹ HDroxyethyl.MHEC jẹ diẹ sooro si iyọ, ni irọrun tiotuka ninu omi ati pe o ni iwọn otutu gel ti o ga julọ.
MHEC ni a tun mọ ni HEMC, Methyl Hydroxyethyl Cellulose, eyiti o le ṣee lo bi oluranlowo idaduro omi to munadoko, amuduro, adhesives ati oluranlowo fiimu ni ikole, awọn adhesives tile, simenti ati awọn pilasita orisun gypsum, ohun elo omi, ati ọpọlọpọ awọn ohun elo miiran.
