Te pūhui hauwaioraitiri (HEC)He etera cellulose kore-ionic i hangaia mai i te rauemi polymer tūturu cellulose mā te raupapa etherification. He paura ma, he kirikiri rānei, kāore he kakara, kāore he reka, kāore he paitini, ka taea te rewa ki te wai matao hei hanga i tētahi otinga matotoru mārama, ā, kāore te uara pH e pāngia e te rewatanga. He āhuatanga whakamātotoru, here, horapa, whakaemulsifying, hanga kiriata, whakatārewatanga, mimiti, hohe mata, pupuri makuku me te ātete tote. He whānuitia te whakamahinga i roto i te peita, te hanga, te kakahu, te matū o ia rā, te pepa, te keri hinu me ētahi atu ahumahi.
Ngā wāhi tono matua:
1.Peita: Ko te peita wai-wai he wai matotoru i hangaia ki ngā whakarewa waro, ki te wai rānei i runga i te kapia, i te hinu rānei, i te whakaehu rānei, me te tāpiri i ngā tāpiringa e rite ana. Ko ngā paninga wai-wai me te mahi tino pai me whai mahi tino pai, he kaha huna pai, he piri kaha ki te paninga, me te mahi pupuri wai pai; ko te cellulose ether te rauemi mata tino pai hei whakarato i ēnei āhuatanga.
2. Hanganga: I roto i te ao hanga, ka whakamahia te HEC hei tāpiri mō ngā rauemi pēnei i ngā rauemi pakitara, te raima (tae atu ki te uku), ngā taera whakapiri me ngā rauemi whakakikorua, ka taea te whakanui ake i te matotoru me te matotoru o ngā rauemi hanga, te whakapai ake i te piri, te hinu, me te pupuri wai. Ka whakarei ake i te kaha piko o ngā wāhanga, te whakapai ake i te whakaheke, me te karo i ngā kapiti taha.
3. Kakahu: Ka whakapai ake te miro kua maimoatia ki te HEC, ngā muka hangai, ngā ranunga rānei i ō rātou āhuatanga pēnei i te ātete ki te pakū, te āheinga ki te tae, te ātete ki te ahi me te ātete ki te paru, me te whakapai ake hoki i te pumau o te tinana (te whakaheke) me te roa, inā koa mō ngā muka hangai, e āhei ai te manawa me te whakaiti i te hiko pateko.
4. Matū o ia rā: He mea nui te cellulose ether i roto i ngā hua matū o ia rā. Ehara i te mea ka taea anake te whakapai ake i te matotoru o ngā mea whakapaipai wai, ngā mea whakapaipai whakapūkara rānei, engari ka whakapai ake hoki i te marara me te pumau o te pahuka.
5. Pepa: I roto i te mara o te hanga pepa, ka taea te whakamahi i te HEC hei kaihoko rahi, hei kaihoko whakapakari me te whakarerekē pepa.
6. Te keri hinu: Ko te HEC te mea nui hei whakamātotoru me te whakau i roto i te tukanga maimoatanga o te mara hinu. He matū pai ki te mara hinu. I whakamahia whānuitia i roto i te keri, te whakaoti puna, te whakakī raima me ētahi atu mahi whakaputa hinu i ngā whenua ke i ngā tau 1960.

Ka taea e te Hydroxyethyl cellulose te whakapai ake i te kaha mākū me te whakaiti o te onepu sima me ngā pūnaha onepu silicate konutai. Ka taea te whakamahi i te Hydroxyethyl cellulose i roto i te hanga kiriata me te hei whakamarara i roto i te hanga kiriata moroiti. Whakamātotoru i roto i ngā wai he nui te kukū tote e whakamahia ana i roto i te tukatuka kiriata. Whakamahia hei here me te whakamarara pumau mō ngā kaihoko fluorescent i roto i ngā paninga ngongo fluorescent. Ka taea e ia te tiaki i te colloid mai i te awe o te kukū electrolyte; Ka taea e te hydroxyethyl cellulose te whakatairanga i te whakatakotoranga ōrite i roto i te otinga whakakikorua cadmium. Ka taea te whakamahi hei hanga here kaha-tiketike mō ngā uku. Ka ārai ngā ārai wai i te makuku kei uru ki ngā taura kua pakaru.
