Ko te paura pūmua ka taea te whakamarara anō (RDP) he pūmua e whakamahia ana hei tāpiri i roto i ngā moata ranunga maroke. Ko te RDP he paura i hangaia mā te whakamaroke i te ranunga pūmua. Ina tāpirihia te RDP ki te wai, ka hangaia he ranunga pumau ka taea te whakamahi hei hanga moata. He maha ngā āhuatanga o te RDP e waiho ana hei tāpiri whai hua i roto i ngā moata ranunga maroke. Kei roto i ēnei āhuatanga:
Te pupuri wai: Ka āwhina te RDP ki te pupuri wai i roto i te moata, ka whakapai ake i te mahi a te moata, ka whakaiti hoki i te nui o te wai e hiahiatia ana.
Piripiri: Ka taea e te RDP te whakapai ake i te piri i waenga i te moata me te papa, ā, ka whakapai ake i te kaha me te roa o te moata.
Te Āhua Mahi: Ka taea e te RDP te whakapai ake i te kounga o te hua kua oti mā te whakangāwari ake i te tukatuka i te moata.
Te Pakari: Ka taea e te RDP te whakanui ake i te pakari o te moata, kia ātete ake ai ki te ngatata me te huarere.
He tāpiringa maha-mahi te RDP ka taea te whakamahi i roto i ngā momo mota ranunga maroke. He tino pai mō ngā mota e whakamahia ana i roto i ngā tono o waho pērā i te stucco me ngā piripiri taera. Ka taea hoki te whakamahi i te RDP i roto i ngā mota e whakamahia ana i roto i ngā tono o roto pērā i ngā whakakī hononga me ngā matū whakatika.
Anei ētahi painga o te whakamahi i te RDP i roto i te moata ranunga maroke:
Whakapai ake i te pupuri wai
Whakapai ake i te piri
Whakapai ake i te ngāwari o te mahi
te roa o te mau
whakaitihia te pakaru
whakaitihia te kino o te wai
whakanui ake i te ngāwari
Whakapai ake i te ātete ki te huarere
He tāpiri haumaru, he whai hua hoki te RDP ka taea te whakamahi hei whakapai ake i te mahi a te moata ranunga maroke. He taputapu tino whai hua tēnei mā ngā kaimahi kirimana me ngā kaihanga e hiahia ana ki te whakaputa moata pakari, kounga teitei.
Anei ētahi o ngā momo RDP e whakamahia whānuitia ana i roto i te moata ranunga maroke:
Vinyl Acetate Ethylene (VAE): Ko te VAE RDP te momo RDP tino noa. He kōwhiringa maha-whakamahinga, he iti hoki te utu, ka taea te whakamahi i roto i ngā momo moata.
Styrene Butadiene Acrylate (SBR): He utu nui ake te SBR RDP i te VAE RDP, engari he pai ake te pupuri wai me te piri.
Polyurethane (PU): Ko te PU RDP te momo RDP utu nui rawa atu, engari he pai rawa atu te pupuri wai, te piri me te pakari.
