Te Pūtauora Waikawa (HEC)
Hydroxyethyl Cellulose(HEC)
CAS:9004-62-0
Hydroxyethyl CelluloseKo te (HEC) he cellulose ether wai-wairewa kore-ionic, e whakamahia ana hei whakamātotoru, hei colloid tiaki, hei kaihoko pupuri wai me te whakarerekē rheology i roto i ngā tono rerekē pēnei i ngā peita wai, ngā rauemi hanga, ngā matū mara hinu me ngā hua tiaki whaiaro. Nā ōna āhuatanga tino pai, pēnei i te matotoru teitei, te wairewa i roto i te wai wera me te wai matao, me te pumau matū, he wāhanga nui te HEC i roto i te maha o ngā hua ahumahi me ngā hua kaihoko.
Ka hangaia te HEC mā te whakauru i ngā rōpū hydroxyethyl (-CH₂CH₂OH) ki roto i te mekameka cellulose polymer mā te tauhohenga etherification. Ka whakapai ake tēnei whakarerekētanga i tōna wairewatanga wai, tōna kaha ki te whakamātotoru, me te hototahi ki ngā momo hanganga rerekē.

Ngā Painga Matua:
1. He Pai rawa te Pupuri Wai: Āwhina ki te ārai i te maroke wawe o ngā hua me ngā mea whakapaipai e hangai ana ki te sima.
2. Pūmau puta noa i te whānuitanga o te pH: Ka noho whai hua tonu i roto i ngā taiao waikawa, kūpapa, me te kawakore.
3. Kore-Ionic, Hototahi hoki: He pai te mahi tahi me ngā matū rerekē, tae atu ki ngā tote, ngā surfactants, me ētahi atu polymers.
4. Whakapai ake i te Mahi a te Hua: Whakapai ake i te matotoru, te piri, te hanga kiriata, me ngā āhuatanga whakaemulsification.
5. He pai mō te taiao, ā, ka pirau: I ahu mai i te cellulose, kāore he paitini o te HEC, ā, ka pirau hoki.
6. Whakapai ake i te Rheology me ngā Āhuatanga Rere: Ka taea te whakahaere i te matotoru, te ārai i te maturuturu, te totohu, me te wehenga wāhanga.
Tākai:
Kei roto i te putea pepa paparanga e toru te hua HEC, ā, kua whakapakaritia te putea polyethylene o roto, ko te taumaha kupenga he 25kg mō ia putea.
Rokiroki:
Puritia i roto i te whare putunga matao, maroke, kia matara atu i te makuku, te rā, te ahi, te ua.
