Te hauota hauwai etiretira (9004-62-0)

Ko te Hydroxyethyl cellulose ether, me te tauira matū (C6H10O5)n·(C2H6O)n, he pūmua wairewa-wai i ahu mai i te cellulose. E mōhiotia whānuitia ana ko te hydroxyethylcellulose (HEC). Ko te nama rēhita CAS mō te hydroxyethyl cellulose ko 9004-62-0.

Ka puta te HEC mā te tauhohenga i te cellulose alkali ki te ethylene oxide i raro i ngā āhuatanga whakahaere. Ko te hua he paura mā ki te mā, kāore he kakara, kāore hoki he reka, ka wairewa i roto i te wai matao me te wai wera. Ka whakamahia te HEC i roto i ngā ahumahi maha mō ōna āhuatanga whakamātotoru, whakaū, me te hanga kiriata. Ko ētahi o ngā whakamahinga noa o te HEC ko:

1. Ngā Hua Tiaki Whaiaro: Ka whakamahia te HEC i roto i ngā hopi horoi makawe, ngā whakangawari makawe, ngā hinu kiri, ngā kirimi, me ētahi atu taonga tiaki whaiaro hei whakamātotoru, hei whakaū, hei here hoki.
2. Rongoā: I roto i ngā whakatakotoranga rongoā, ka mahi a HEC hei kaiwhakamātotoru i roto i ngā wai ā-waha, hei here i roto i ngā whakatakotoranga papa, me te whakaū i roto i ngā whakatārewatanga.
3. Ngā Rauemi Hanga: Ka tāpirihia te HEC ki ngā rauemi hanga pērā i ngā piripiri taera, ngā paninga sima, me ngā pāreti kei roto i te gypsum hei whakapai ake i te mahi me te pupuri wai.
4. Ngā Peita me ngā Paninga: Ka whakamahia te HEC hei whakarerekētanga rheology me te whakamātotoru i roto i ngā peita wai-pūtake, ngā paninga, me ngā piripiri hei whakahaere i te matotoru me te whakarei ake i ngā āhuatanga tono.
5. Ngā Hua Kai: E whakamahia ana te HEC i roto i ngā mahi kai pēnei i ngā ranu, ngā ranu, me ngā kai reka hei whakamātotoru me te whakau.
