Paura Pūmua Whakamarara Anō (RDP), hei piripiri rauropi tino nui i roto i ngā pūnaha moata whakamahana wera hou, ka whakarei ake i te kaha o te here, te ngāwari, te ātete ki te pakaru, me te mahi o te moata. Heoi, i roto i ngā pūnaha whakamahana pakitara o waho e whakaatuhia ana ki ngā taiao uaua pēnei i te rā, te ua, ngā huringa wera, me te horo o te hau i roto i ngā wā roa, ka noho te ātete huarere o te RDP hei mea matua e whakatau ana i te roa o te mahi a te pūnaha. Mā te tātari i ngā āhuatanga hanga kiriata, te hanganga polymer, me te pānga ki te hanganga moroiti o te moata o te RDP ka taea te aromatawai pūnaha ake i tōna ātete huarere i roto i te moata whakamahana wera.
1.Ko te ātete huarere o te RDP i roto i te moata whakamahana wera e ahu mai ana i tōna hanganga whatunga polymer i muri i te hanganga o te kiriata. Ko te RDP he mea hanga i ngā pūnaha polymer pēnei i te ethylene-vinyl acetate (VAE) me ngā acrylates, he pai te ngāwari me te ātete ki te koroheketanga UV. Ina horahia anō te RDP i te wā o te tukanga whakapakeke moata, ā, ka rongoa tahi me ngā rauemi sima kore-ora, ka hangaia he kiriata polymer tonu i roto i ngā pūwero moata me te mata o te konganuku. Ehara i te mea ka whakarei ake tēnei kiriata angiangi i te piri o te mata engari ka whakapai ake hoki i te ātete wai me te ātete huka-rewa o te pūnaha moata, ka taea ai te pupuri i te mahi pumau i roto i te huringa wera mo te wā roa.
2.He nui te whai wāhi a te RDP ki te ātete ki ngā pakaru me te ngāwari o te moata whakamahana wera, ā, ka pai ake tōna ātete ki te huarere. He ngāwari ngā pūnaha whakamahana pakitara o waho ki te horapa wera me te whakaiti i te ahotea nā te nui o ngā rerekētanga pāmahana o waho. Mena kāore te moata, hei paparanga tiaki, e ngāwari ana ki ngā pakaru moroiti, ka taea ai te mimiti o te wai ua, ka tere ake te koroheketanga. Ka mimiti pai te ngāwari o te kiriata RDP i te ahotea, ka whakaiti i te kukū ahotea o roto i puta mai i te whakarerekētanga o te papa, i ngā huringa pāmahana rānei, ā, ka whakaiti i te hanganga pakaru me te whakapai ake i te pumau whānui o te hanganga moata i raro i ngā āhuatanga ratonga o waho mō te wā roa.
3.Ko te whakapainga RDP i te ātete wai o te moata he tohu matua anō hoki mō te ātete ki te huarere. Me pupuri e te moata whakamahana te tere mimiti wai iti i roto i ngā taiao ua, haumākū rānei. Ko te pai o te ātete wai o te kiriata polymer RDP ka whakaiti i te mimiti wai capillary, ka aukati i ngā ara urunga wai, ā, ka whakaiti i te tūponotanga o te kino tio-rewa. Kua whakaatuhia e ngā rangahau mā te tāpiri i te nui o te RDP tika ki te moata whakamahana ka taea te whakaiti i tōna tere mimiti wai mā te 30% ki te 50%, ā, ka whakapai ake hoki i tōna tere pupuri kaha i muri i te rumaki roa ki roto i te wai, kia mau ai te hanganga o te pūnaha.
4.Mā te whakapai ake i te hanganga moroiti o te moata i raro i te RDP ka kaha ake tōna ātete ki te koroheketanga. Whai muri i te mararatanga, ka whakakīia ngā āputa i waenga i ngā hua whakamakuku sima e ngā matūriki polymer, ka pai ake te tohatoha rahi o ngā pore, ā, ka hangaia he hanganga ōrite, kiato hoki i roto i te moata. Ehara i te mea ka whakapai ake i ngā āhuatanga miihini anake tēnei kiato, engari ka kaha ake te ātete o te moata ki ngā āhuatanga waikura o waho (pērā i te hauhā waro me ngā tote pūhaumāota), ā, ka roa ake te ora o te pūnaha whakamahana.
5.He mea tika kia mōhiotia he rerekē te ātete o ngā momo RDP ki te huarere. Hei tauira, he pai ake te ātete o te VAE-RDP ngāwari ki te huka-rewa me te ātete ki te pakaru; engari he pai ake te mahi a te RDP kiriaku parakore ki te ātete ki te koroheketanga UV me te ātete ki te kōwhai. Nō reira, i roto i ngā mahi whaihua, me whiriwhiri te momo me te nui o te RDP e tika ana i runga i ngā āhuatanga o te pūnaha moata whakamahana wera, te taiao hanga, me te roa o te hoahoa.
6.Ngā painga o te ātete ki te huarereRDPKo te nuinga o ngā āhuatanga o te moata whakamahana wera e kitea ana i roto i te pumau o te hanganga hanga kiriata, te ngāwari ake, te ātete wai ake, me te hanganga moroiti kua whakapaitia. Mā ēnei āhuatanga ka taea e ia te ātete pai ki ngā kino i puta mai i te huringa āhuarangi roa o te pakitara o waho, ā, ka whakapai ake i te roa o te ora me te roa o te mahi o te pūnaha whakamahana o waho.
