Hydroxyethyl Cellulose Etera

Ko te Hydroxyethyl cellulose ether he waerau katote-kore-wai-wairewa, ka whakarewahia i roto i te wai wera me te wai matao.Ko te Hydroxyethyl cellulose ether he maha nga momo pokey, a ko nga wairewa wai katoa ehara i te Newtonian.

Hydroxyethyl cellulose ether he tino pai nga ahuatanga whakamakuku.He maeneene, he rite hoki tana wairewa wai, he pai te rere me te whakataurite

Ko te tauira hanganga rāpoi pai o te hydroxyethyl cellulose ether e whai ake nei:

N = tohu whakahiato

E toru nga roopu hydroxyl i ia wae anhydroglucose i roto i te cellulose, ka tukuna ki te kawakore i roto i te wairewa konutai konutai wai hei tiki i te tote konutai cellulose, katahi ka uru ki te tauhohenga etherification ki te ethylene oxide ki te hanga hydroxyethyl cellulose ether.I roto i te tukanga o te whakahiato HEC, e kore e taea e te ethylene oxide anake te whakakapi i nga roopu hydroxyl i runga i te cellulose, engari ka tukuna ano he tauhohenga polymerization mekameka me nga roopu hydroxyl i roto i nga roopu whakakapi.
