Ko ngā etera cellulose he momo polymer wairewa-wai i ahu mai i te cellulose taiao kua whakarerekētia i roto i ngā matū. Ko ngā momo noa kohydroxypropyl methylcellulose (HPMC), methylcellulose (MC), te hauwaitoitirīseloro (HEC), te carboxymethylcellulose (CMC), mete methylhydroxyethylcellulose (MHEC)Ka whakakotahihia e rātou te haumaru o te cellulose tūturu me ngā āhuatanga ā-tinana me te matū pai rawa atu o te cellulose kua whakarerekētia. He tino pai rātou ki te whakamātotoru, te pupuri wai, te hanga kiriata, te here, te horapa, te whakaemulsification, me te whakatārewatanga. Nō reira, he whānuitia te whakamahinga i roto i ngā ahumahi pēnei i te hanga whare, ngā rongoā, te kai, ngā matū o ia rā, te hinu, te hanga pepa, me ngā paninga.
1. Te Ahumahi Hanga me ngā Rauemi Hanga
Ko te hanga whare te mākete tono nui rawa atu mō ngā etera cellulose, inā koa i roto i ngā rauemi pēnei i te moata ranunga maroke, ngā piripiri taera, te paura putty, te whakataurite-ake, te moata sima, me ngā hua gypsum.
Te Pupuri Wai: I roto i ngā rauemi sima me te gypsum, ka taea e ngā cellulose ethers te whakaroa i te mimiti o te wai, kia tino makuku ai te rauemi sima, kia pai ake ai tōna kaha. Te Whakapai Ake i te Āhua Mahi: Ka whakarei ake i te hinuhinu me te thixotropy o te moata, ka āwhina i te whakangawari me te whakaroa i te āhua mahi.

Ngā Hua Tunu Parāoa: Ka whakapai ake te HPMC i te hanganga o te paraoa pokepoke, ka pupuri i te wai, ā, ka whakapiki i te ngawari o te taro me ngā keke.
Ngā mea tiaki me ngā mea hanga kiriata: Ka hanga he kiriata kai ki runga i ngā hua, ka roa ake te ora o te penapena.
4. Ngā Matū o ia Rā me ngā Hua Tiaki Whaiaro
Ka whakaratohia e ngā etera cellulose ngā āhuatanga pumau me te whakarerekē i te kakano i roto i ngā hopi horoi, ngā mea whakapaipai, me ngā hua tiaki kiri. Ngā mea whakamātotoru me ngā mea whakatārewatanga: He mea whakamahi noa te HEC i roto i ngā hopi horoi me ngā horoi tinana hei whakatutuki i te matotoru e hiahiatia ana, hei whakaū hoki i ngā kakara me ngā matūriki whakatārewatanga.
Ngā kai whakamakuku: Ka hangaia e te HPMC me te CMC he kiriata whakamakuku ki te mata o te kiri, hei ārai i te ngaronga o te wai.
Whakapūmau i te emulsion: He mea whakapūmau i te emulsion i roto i ngā kirīmi me ngā hinu kiri.
Papa parai niho: Ka whakamahia te CMC-Na hei here me te whakamātotoru i roto i te parai niho, hei whakaputa i te ahua pai me te maeneene.
5. Te Tango Hinu me te Hau
He mea nui anō hoki ngā whakamahinga o ngā cellulose ethers i roto i ngā wai keri me ngā tukanga whakaora hinu.
Ngā kaihoko whakahaere i te ngaronga wai: Ka taea e te CMC me te PAC (modified carboxymethyl cellulose) te whakaiti i te ngaronga wai i roto i ngā wai keri me te tiaki i ngā hanganga hinu me te hau.
Ngā whakarerekētanga rheology: Ka whakapai ake i te matotoru me te rere o te wai keri, ka whakahaere i te kawe o ngā tapahi keri.
