Ko te Hydroxyethyl cellulose (HEC) he polymer wairewa-wai e whakamahia ana i roto i nga momo tono penei i te whakapiri, te paninga, me nga hua tiaki whaiaro.Ko te whakakore i te HEC i roto i te wai he mahinga ngawari ka taea te whakatutuki ma te whakamahi i nga waahanga e whai ake nei:
Kōwhiria te kōeke tika o HEC: Kei te wātea te HEC ki ngā momo kōeke me ngā taumahatanga rāpoi rerekē me ngā nekehanga whakakapinga.Ko te kowhiringa o te karaehe ka whakawhirinaki ki te tono motuhake me nga ahuatanga e hiahiatia ana o te hua whakamutunga.
Whakaritehia te wai: Ko te mahi tuatahi ko te whakarite i te wai ma te ine i te nui o te wai e hiahiatia ana me te whakamahana ki te mahana i waenga i te 70-80°C.Ko te whakamahana i te wai ka awhina ki te whakatere i te tukanga whakakore me te whakarite kia tino waia te HEC.
Tāpirihia te HEC ki te wai: Kia tae te wai ki te pāmahana e hiahiatia ana, āta tāpirihia te HEC ki te wai me te kōrori tonu.He mea nui ki te taapiri i te HEC kia ata noho kia kore ai e kopiri me te whakarite kia marara katoa ki roto i te wai.
Me whakaoho tonu: I muri i te taapiri i te HEC ki te wai, haere tonu te whakaoho i te ranunga mo te 30 meneti.Ka awhina tenei ki te whakarite kia tino rewa te HEC me te wai.
Tukua kia whakamatao te ranunga: I muri i te rewa katoa o te HEC, tukua te ranunga kia whakamatao ki te pāmahana rūma.Ka mātao te ranunga, ka mātotoru, ka tae ki tōna pōkākā whakamutunga.
Whakaritea te pH me te viscosity: I runga i te tono motuhake, ka tika pea ki te whakatika i te pH me te viscosity o te otinga HEC.Ka taea tenei ma te taapiri i te waikawa, te turanga ranei hei whakatika i te pH me te taapiri i te wai, i etahi atu HEC ranei hei whakatika i te pokey.
Ko te whakakore i te HEC i roto i te wai he mahinga ngawari ka taea te whakatutuki me etahi waahanga iti.Ma te whiriwhiri i te tohu tika o te HEC, te whakarite tika i te wai, me te whakaoho tonu i te ranunga, ka taea te whiwhi i te otinga HEC tino memeha ka taea te whakamahi i roto i nga momo tono.
