Te pupuri wai o te hydroxypropyl methylcellulose

Ko te Hydroxypropyl methylcellulose (HPMC) he ether cellulose kore-ionic i hangaia mai i te rauemi polymer tūturu cellulose mā roto i te raupapa o ngā tukanga matū. Ko te Hydroxypropylmethylcellulose (HPMC) he paura ma, kāore he kakara, kāore he reka, kāore he paitini, ka taea te whakarewa ki te wai matao hei hanga i tētahi otinga matotoru mārama. Kei a ia ngā āhuatanga o te whakamātotoru, te here, te horapa, te whakaemulsifying, te hanga kiriata, te whakatārewatanga, te mimiti, te whakapūmau, te whakakaha mata, te pupuri i te makuku me te tiaki i te colloid. I roto i te moata, ko te mahi nui o te hydroxypropyl methylcellulose ko te pupuri wai, arā, te kaha o te moata ki te pupuri wai.

1. Te hiranga o te pupuri wai mō te moata

He ngāwari te toto me te wehewehe i te moata kāore i te pai te pupuri wai i te wā e kawe ana, e penapena ana hoki, arā, ka mānu te wai i runga, ka totohu te onepu me te sima i raro, ā, me whakaoho anō i mua i te whakamahinga. Mō te moata kāore i te pai te pupuri wai, i te wā e pania ana, i te mea kei te pā tonu te moata kua oti te whakaranu ki te poraka, ki te turanga rānei, ka mimiti te moata kua oti te whakaranu e te wai, ā, i taua wā anō, ka mimiti te mata o waho o te moata ki te hau, ka ngaro te wai o te moata. Ki te kore e ranea te wai, ka pāngia te makuku o te sima, ka pāngia hoki te whanaketanga noa o te kaha o te moata, ka iti ake te kaha, inā koa te kaha o te hononga i waenga i te moata kua whakapakeketia me te paparanga turanga, ka pakaru, ka taka atu i te moata.

2. Te tikanga tuku iho mō te whakapai ake i te pupuri wai o te moata

Ko te otinga tuku iho ko te whakamakuku i te turanga, engari kāore e taea te whakarite kia ōrite te makuku o te turanga. Ko te whāinga whakamakuku pai o te moata sima i runga i te turanga ko: ka uru te hua whakamakuku sima ki roto i te turanga me te tukanga o te wai e mimiti ana i te turanga, ka hanga he "hononga matua" whai hua ki te turanga, kia tutuki ai te kaha here e hiahiatia ana. Mā te whakamakuku tika ki runga i te mata o te turanga ka nui te horapa o te mimiti wai o te turanga nā te rerekētanga o te pāmahana, te wā whakamakuku, me te ōritetanga o te whakamakuku. He iti ake te mimiti wai o te turanga, ā, ka mimiti tonu i te wai i roto i te moata. I mua i te haere tonu o te whakamakuku sima, ka mimitihia te wai, ka pā ki te urunga o te whakamakuku sima me ngā hua whakamakuku ki roto i te anga; he nui te mimiti wai o te turanga, ā, ka rere te wai i roto i te moata ki te turanga. He puhoi te tere hekenga waenga, ā, ka hangaia he paparanga wai-nui i waenganui i te moata me te anga, ka pā hoki ki te kaha here. Nō reira, mā te whakamahi i te tikanga whakamakuku turanga noa, ehara i te mea ka kore e taea te whakatau i te raruraru o te mimiti nui o te wai ki te turanga pakitara, engari ka pā ki te kaha o te here i waenga i te moata me te turanga, ka hua ake he poka me te ngatata.

3. Te pupuri wai pai

(1) Nā te pai o te mahi pupuri wai ka roa ake te whakatuwheratanga o te moata, ā, he painga anō hoki nō te hanganga whānui, te roa o te ora mahi i roto i te oko, me te whakaranu puranga me te whakamahinga puranga.

(2) Mā te pai o te pupuri wai ka tino makuku te sima i roto i te moata, ka pai ake te mahi piri o te moata.

(3) He tino pai te mahi pupuri wai a te moata, ā, ka iti ake te ngāwari o te wehewehe me te whakaheke toto o te moata, ka pai ake ai te mahi me te hanganga o te moata.
