Tirohia me pēhea te whakapai ake a te Hydroxyethyl Cellulose (HEC) i te mahi a te moata sima me te pupuri wai kia kaha ake, kia roa ake hoki te hanga.
Ko te Hydroxyethyl Cellulose (HEC) he ether cellulose kore-ionic e whakamahia whānuitia ana hei whakarei ake i te rheology me te pupuri wai o ngā moata sima, ka hua ake he mahi pai ake me te wā whakamakuku roa ake mō te kaha me te roa o te wā. Mā te hanga i tētahi whatunga colloidal me te mimiti ki ngā mata matūriki, ka whakanui ake te HEC i te matotoru, ka whakaiti i te ngaronga wai ki roto i ngā papa porous, ā, ka ārai i te maroke wawe - he mea matua i roto i ngā hanganga moata mahi-teitei.
