Hydroxyethyl methyl cellulose (mhec) he wai kore-whakarewa, ka whakaekea hei paura rere koreutu, i roto ranei i te cellose conmular.
Hydroxyethyl methyl cellulose (mhec) i hangaia mai i te hochohenga tino ma te whaikorero i raro i nga tikanga o te alkaline. Kei te whakaatuhia e te hygroscopicity me te tino uaua i roto i te wai wera, acetone, ethanol me toluene. I roto i te wai makariri ka pupuhi te mhec ki te otinga colloidal me tona tino mana e kore e whakaawehia e te ph fence.sifory ki te cellulose i te wa e taapiri ana ki nga roopu HDROXYETYL. He kaha ake te MHEC ki te tote, ka rewa ngawari ki te wai ka nui ake te pāmahana o te kiri.
Kei te mohiotia ano hoki a MSEC ko Hemc, me te methyl hydroxyetyl cellulose, he mea nui, he taapiri me te raima miihini, he maha atu nga tono.
