Kupu Whakataki
Kua neke atu ngā hanganga hou i ngā ranunga onepu-sima tuku iho. Ko ngā pūnaha moata ranunga maroke o ēnei rā he hanganga tino hangarau kua hangaia hei whakatutuki i ngā whakaritenga mahi tino pakari pēnei i te kaha piri, te ātete ki te pakaru, te ngāwari ki te mahi, te pupuri wai, te pakari, me te ātete ki te taiao.
Hei whakatutuki i ēnei āhuatanga, he mea nui te mahi a ngā tāpiringa matū. Ahakoa he iti noa te rahinga e whakamahia ana, ko ngā tāpiringa te mea nui hei whakatau i te mahi whakamutunga o ngā pūnaha moata i tētahi atu wāhanga engari ko te sima.
Ka tūhuratia e tēnei tuhinga tee rima ngā tāpiringa nui mō te moata, ā rātou mahi, ngā tikanga, me te take he mea nui ai rātou i roto i ngā rauemi hanga o ēnei rā.

- Ngā pūnaha EIFS
- Whakatikatika mōta
3. Ngā Kaiwhakaahua Nui (PCE – Polycarboxylate Ether)
Ko ngā superplasticizer he whakaiti wai awhe teitei e whakamahia whānuitia ana i roto i ngā pūnaha sima hou.
Ngā Mahi Matua
Te Whakaiti Wai
Ka whakaitihia e rātou te hiahia mō te wai, ā, ka mau tonu te āheinga mahi.
Whakapai ake i te kaha
Ko te iti o te wai ka hua ake he kaha pēhi teitei ake.
Te Whakarei Rere
Ka whakapai ake i te rere o ngā matū whakaōrite-ake me ngā grouts.
He aha i tino hira ai
Ka taea e ngā superplasticizer te:
- Moata kaha-teitei
- Ngā pūnaha whakataurite-ake
- Ngā tono raima papu
He mea nui rātou mōngā pūnaha sima mahi-teitei, iti-wai.
4. Ngā Kaihoko Whakauru-Hau
Ka whakauruhia e ngā mea whakauru hau ngā mirumiru hau moroiti kua whakahaeretia ki roto i te moata.
Ngā Mahi Matua
Ātete ki te Hukapapa–Te Rewa
Ka mimitihia e ngā āputa hau te pēhanga whakawhanui mai i te wai tio.
Te Whakarei Ake i te Āhua Mahi
Mā ēnei ka māmā ake te pani me te hora i te moata.
Te Whakaiti i te Kiato
Ka pai ake te whakamarumaru wera i te iti o te mātotoru.
He aha i tino hira ai
I ngā āhuarangi makariri, he mea nui ngā mea hei pupuri i te hau mō:
- Pāreti o waho
- Ngā mota whakatikatika rori
- Te hanga i te rangi makariri
Ka tino whakapai ake rātoute manawanui i raro i ngā āhuatanga taiao kino.
5. Ngā Whakaroa me ngā Kaiwhakahaere Tautuhinga

Ko rātou tētahi o ngāngā wāhanga ROI teitei rawa atu i roto i te matū hangahanga.
Ngā Auahatanga Taiao
Kei te piki haere te maha o ngā tāpiringa hou:
- He mea hanga mai i te koiora (ngā mea i ahu mai i te pūtau)
- Iti-VOC
- He pai te penapena pūngao i roto i te whakaputanga
Kei te noho te oranga tonutanga hei kaupapa matua mō te auahatanga tāpiri.
Ko te mahi a te moata hou e whakawhirinaki nui ana ki ngā tāpiringa matū. Ko ngā tāpiringa matua e rima—ngā etera cellulose,RDP, ngā matū hanga kirihou nui, ngā matū whakauru hau, me ngā kaiwhakahaere tautuhinga—ka mahi tahi hei huri i ngā ranunga sima taketake hei rauemi hanga mahi teitei.
Mā te mārama ki ēnei tāpiringa ka taea e ngā kaihanga me ngā kaimahi kirimana te hoahoa i ngā moata e tutuki ai ngā hiahia o te hanganga hou: he kaha ake, he ngāwari ake, he roa ake te mau, ā, he whai hua ake.
I te whanaketanga tonu o ngā paerewa hanga, ka noho tonu te hangarau tāpiri hei kaupapa matua o te auahatanga i roto i ngā pūnaha moata.
