1. Ngā āhuatanga taketake o te MHEC
MHEC (Metila Hauwaioraitiri Hēroro)He etera cellulose kore-ionic tēnei, he pai te matotoru, te pupuri wai, te hanga kiriata, me te whakapai ake i te mahi hanga. I roto i ngā rauemi hanga sima, ka taea e te MHEC te whakapai ake i te rere, te pupuri wai, te ārai-wehewehe me te piri o te moata, ā, he whānuitia te whakamahinga i roto i te piripiri taera, te paura putty, te moata whakataurite-ake, te moata ā-wai me te moata sima uru. Nā tōna pānga iti ki te tukanga whakamakuku sima me te hototahi ki ngā momo ranunga, kua riro te MHEC hei rauemi whakarerekētanga rauropi nui mō te moata sima uru.
2. Ngā āhuatanga o te moata sima ātete-pūngao
Ko te moata sima uru-wai e pā ana ki tētahi moata motuhake ka taea te uru ki roto i te hanganga turanga mā te mahi kapia, ā, he maha ngā wā ka whakamahia i roto i ngā mahi whakatikatika hanganga, whakapakari me te ārai-wai. Me whai i tēnei momo moata:
He pai te uruhanga: ka taea te uru ki roto i ngā pūwero iti o te paparanga turanga me te whakapai ake i te matotoru o te rauemi turanga;
He nui te rere: he pai te rere me te uruhanga, me te kore he toto nui, he wehewehenga rānei;
Te piri kaha me te pakari: kia mau te hononga ki te rauemi turanga, ā, ka whai wāhi ki te whakapakari me te tiaki i te hanganga mō te wā roa;
Te pupuri wai taurite: whakaitihia te ngaronga tere o te wai i te wā hangahanga, me te whakarite kia tino makuku te sima.
Ko te mahi matua a te MHEC he whakapai ake i te rere, te pupuri wai me te mahi hanga o te moata, me te whakapai ake ā-kore i te pānga urunga.
3. Te pānga o te MHEC ki te mahi a te moata sima uruhanga
3.1. Whakapai ake i te pupuri wai me te whakatairanga i te hohonutanga o te urunga
Me pupuri tonu te moata ā-pūwero i te ōritetanga me te makuku e tika ana i mua i te urunga ki roto i ngā pūwero o te paparanga turanga. He tino pai te pupuri wai o te MHEC, ka taea te whakaiti i te mimiti tere o te wai kore utu me te mimiti e te rauemi turanga i te wā o te hanganga moata, ka roa ake te wā urunga o te moata, ka whakanui ake hoki i te hohonutanga o te urunga. Hei tāpiri, he pai hoki te tohatoha wai ōrite ki te makuku katoa o ngā matūriki sima i te wāhanga o muri mai, ka whakapai ake i te matotoru me te pakari.
3.2. Whakapai ake i te rere o te wai me te mahi hanga
Ka taea e te MHEC te whakarerekē i ngā āhuatanga rheological o te moata sima uruhanga, kia mau tonu ai te rere pai o te hanganga i raro i ngā āhuatanga ōwehenga wai-sima iti. Mā te tāpiri MHEC tika ka taea te whakaiti i te toto me te wehewehe o te moata, ā, ka whakarite kia uru ōrite te paru ki roto i ngā pūwero angiangi o te papa. Mō te moata uruhanga e hiahia ana kia ringihia, kia rehuhia rānei, ka taea e te MHEC te whakapai ake i te mahi papu me te whakataurite, kia māmā ake ai te hanga i te moata.
3.3. Whakapai ake i te piri i waenga i te moata me te papa
Nā te āhuatanga hanga kiriata o te MHEC, ka taea te hanga i tētahi kiriata waro ngāwari ki te atanga i te wā e whakapakeketia ana te moata, ka whakarei ake i te ngau ā-mīhini me te piri i waenga i te moata me te papa. Ka āwhina tēnei pānga whakarerekētanga atanga ki te ārai i te moata kei tihore mai i te papa, ā, ka whakapai ake i te pakari whānui o te paparanga whakatikatika uruhanga.
3.4. Whakapai ake i te ātete ki te pakaru me te whakahaere i te mimiti
Nā te nui haere o te mātotoru o roto, ka ngāwari te moata ā-roto ki te mimiti i ngā pakaru i te wā e whakapakeketia ana. Mā te pānga pupuri wai o te MHEC ka taea te whakaroa i te tere mimiti o te moata, te whakapai ake i te makuku o te sima, me te whakaiti i te tūponotanga o ngā pakaru kirihou mimiti. I taua wā anō, mā ngā āhuatanga hanga kiriata o te MHEC ka hoatu he ngāwari ki te moata, ka whakapai ake i te ātete me te roa o te pakaru.
3.5. Mā te whakaroa i te wā whakatakoto tuatahi ka pai ake te hanganga
He iti noa te pānga o te MHEC ki te whakaroa i te tukanga whakamakuku o te sima, ā, ka āwhina tēnei ki te whakaroa i te wā mahi o te moata. Mō ngā kaupapa whakatika e hiahia ana kia uru katoa, mā te wā hanga roa ake ka māmā ake te uru o te paru ki roto i te paparanga turanga, ka pai ake te pānga whakatika me te pumau o te kounga.
3.6. Whakapai ake i te mahi ārai-mimi me te ātete-wai
I roto i te moata ātete-whakapakari, nā te mea ka whakapai ake te MHEC i te kiato me te hononga atanga o te moata, ka ōrite ake tōna hanganga capillary, ka whakaitihia te poresity, ā, ka tino whakapaitia te kaha ārai-mimi. I roto i te ārai-wai i raro i te whenua, te arai kauhanga, te puna wai me ētahi atu kaupapa, ka taea e te moata ātete-whakarerekētia a MHEC te aukati i te hekenga o te makuku me te whakarei ake i te pānga ārai-wai.
4. Te nui o te tāpiri me ngā whakatūpato mō te whakamahinga
Te nui o te tāpiri i tūtohutia: ko te tikanga he 0.2% ki te 0.6% o te papatipu o te rauemi sima, me whakarerekē i tēnei kia rite ki te ōwehenga wai-sima, te rere o te moata me te tukanga hanga.
Āraia te tāpiri nui rawa: Mā te nui rawa o te MHEC ka nui rawa te matotoru o te moata, ka iti ake te uruhanga o te moata, ā, ka roa pea te totoka o te sima.
Te hototahitanga me ētahi atu ranunga: I roto i ngā moata uruhanga kei roto ngā mea whakaiti wai, ngā mea whakauru hau, ngā mea whakawhānui rānei, me whakatau te horopeta tino pai o te MHEC mā te whakamātautau kia pai ai te mahi tahi.
I roto i te moata sima uruhanga, ka whakapai ake te MHEC i te hohonutanga o te urunga, te piri, te ātete ki te pakaru me te roa o te moata mā roto i ōna āhuatanga pupuri wai, whakamātotoru, hanga kiriata me te whakatikatika rheological. I taua wā anō, ka whakapai ake i te mahi hanga, ka whakaroa i te wā hanga, ā, ka whakapai ake i te kounga whānui o ngā kaupapa whakatika me te tiaki. Te whiriwhiri me te whakahaere tika i te nui o te tāpiri oKo te MHEC te mea nui ki te whakatutuki i te mahi teitei o te moata sima permeables.
