Hydroxyethyl Cellulose

Ko te Hydroxyethyl cellulose (HEC) he ether cellulose wairewa kore-ionicngā hua whakawhitika taea te noho tahi me te maha atu o ngā pūmua wairewa-wai, ngā matū horoi, me ngā tote. Kei a HEC ngā āhuatanga o te whakamātotoru, te whakatārewatanga, te piri, te whakaemulsification, te hanganga kiriata pumau, te marara, te pupuri wai, te tiaki anti-microbial me te tiaki colloidal. Ka taea te whakamahi whānuitia i roto i ngā paninga, ngā whakapaipai, te keri hinu me ētahi atu ahumahi.

Ngā āhuatanga matua oHte hidroksietiri o te pūtau(HEC)Ko te take he taea te rewa ki te wai matao me te wai wera, ā, kāore he āhuatanga tiēre. He whānuitia te whakakapinga, te wairewatanga me te matotoru. He pai te pumau o te wera (i raro i te 140°C) ā, kāore e puta he ua i raro i ngā āhuatanga waikawa. Ka taea e te otinga hydroxyethyl cellulose te hanga i tētahi kiriata mārama, he āhuatanga kore-ionic kāore e taunekeneke ki ngā ion, ā, he pai te hototahitanga.

Cngā āhuatanga o HEC

1.Te whakamātotoru

He mea whakamātotoru pai te HEC mō ngā paninga me ngā mea whakapaipai. I roto i ngā mahi whaihua, mā te whakakotahitanga o te whakamātotoru me te whakatārewatanga, te haumaru, te marara, me te pupuri wai ka hua ake he hua tino pai.

2.Te āhua rūpahu

Ko te āhua o te pseudoplasticity e pā ana ki te āhuatanga e heke ana te matotoru o te wairewa i te pikinga o te tere. He ngāwari te pania o te peita rapa kei roto he HEC ki ngā paraihe, ki ngā roera rānei, ā, ka taea te whakanui ake i te maeneene o te mata, ka taea hoki te whakanui ake i te pai o te mahi; he pai te rere o ngā hopi horoi kei roto he HEC, ā, he tino matotoru, he ngāwari ki te waimeha, ā, he ngāwari ki te marara.

3.Te manawanui ki te tote

He tino pumau te HEC i roto i ngā wai tote kukū-teitei, ā, e kore e pirau ki te āhua ionic. Mēnā ka whakamahia ki te whakakikorua hiko, ka taea te whakapai ake i te mata o ngā wāhanga whakakikoruatia, ka kanapa ake. Ko te mea nui ake, he pai tonu te matotoru ina whakamahia ki te peita rapa kei roto ko te borate, te silicate me te carbonate.

4.Te hanga kiriata

Ka taea te whakamahi i ngā āhuatanga hanga kiriata o te HEC i roto i ngā ahumahi maha. I roto i ngā mahi hanga pepa, ka taea e te paninga ki te kaihopu karaihe kei roto he HEC te aukati i te urunga o te hinu, ā, ka taea hoki te whakamahi hei whakarite otinga mō ētahi atu āhuatanga o te hanga pepa; i roto i te tukanga miro, ka taea e te HEC te whakanui ake i te ngāwari o ngā muka me te whakaiti i te kino ā-mīhini ki a rātou. I roto i te tukanga rahi, tae me te whakaoti o te papanga, ka taea e te HEC te mahi hei kiriata tiaki rangitahi. Ki te kore e hiahiatia tōna tiaki, ka taea te horoi atu i te muka ki te wai.

5.Te pupuri wai

Ka āwhina te HEC ki te pupuri i te makuku o te pūnaha ki tōna āhua pai. Nā te mea he iti noa te HEC i roto i te wairewa ka taea te pupuri i te wai, ā, ka whakaitihia te hiahia wai o te pūnaha i te wā e whakaranua ana. Ki te kore he wai e pupurihia ana, e piri ana rānei, ka whakaitihia te kaha me te piri o te moata sima, ā, ka whakaitihia hoki te kirihou o te uku i raro i tētahi pēhanga.
