Ka rite ki te surfactant katote kore,hydroxyethyl cellulose(HEC) e whai ake nei nga ahuatanga hei taapiri atu ki te whakamatotoru, ki te whakatarewa, ki te here, ki te rewa, ki te hanga kiriata, ki te marara, ki te pupuri i te wai me te whakarato colloids whakamarumaru:
1. He wairewa te HEC i roto i te wai wera, i te wai matao ranei, karekau e pupuhi i te pāmahana teitei, te koropupuke ranei, no reira he maha nga ahuatanga o te whakarewatanga me nga ahuatanga pokey, me te waiariki kore;
2. Ka taea e te katote-kore ake te noho tahi me etahi atu polymers wairewa-wai, surfactants me nga tai i roto i te whanuitanga whanui, a he pai rawa atu te katoo colloidal kei roto i nga otinga electrolyte teitei;
3. Ko te kaha o te pupuri i te wai e rua ake te teitei o te methyl cellulose, a he pai ake te whakahaere o te rere.
4. Ka whakatauritea ki te methyl cellulose me te hydroxypropyl methyl cellulose, ko te kaha marara o HEC te mea kino rawa atu, engari ko te kaha o te colloid tiaki te kaha rawa atu.
Me pehea te whakamahi i te hydroxyethyl cellulose？
1. Whakauru tika ki te hanga
1. Taapirihia he wai ma ki roto i te peere nui e mau ana ki te miihini kutikuti teitei.
2. Tīmatahia te kōrori i te tere iti, ka tatari kia ata rite te waikura hydroxyethyl cellulose ki roto i te otinga.
3. Whakakorikori tonu kia ruku nga matūriki katoa.
4. Katahi ka taapirihia he kaihoko whakamarumaru uira, he taapiri kawakore penei i te poaka, he awhina whakamarara, he wai haukini.
5. Oho kia rewa katoa te hydroxyethyl cellulose (ka tino piki te pokey o te wairewa) i mua i te taapiri i etahi atu waahanga ki roto i te tauira, ka huri kia huri noa.
