I roto i ngā hanganga piripiri taera,paura pūmua ka taea te whakamarara anō (RDP)He tāpiringa pūmua waro nui te mea nei. Ko tana mahi te mea e whakatau tika ana i ngā āhuatanga here o te piri, te ngāwari, me te roa o te piri. Ko te piri tāera, he hua moata ranunga maroke noa i roto i te hanganga, e whakamahia ana hei here i ngā rauemi whakaoti pēnei i te uku, ngā tāera whakakoi, me te māpere. Ko te whakawhirinaki anake ki ngā hua whakamakuku o te sima ka kore e tutuki i te kaha here me te roa e hiahiatia ana. Nō reira, ko te tāpiri o te RDP ehara i te mea ka whakapai ake i ngā āhuatanga ā-tinana o ngā piri sima engari ka whakanui ake hoki i tā rātou tono me te mahi roa.
1. Te Whakapai Ake i te Kaha o te Here
Me kaha te piri tuatahi me te kaha piri mō te wā roa mō ngā piripiri taera kia mau ai te piri o ngā taera ki te papa. I te wā e whakamakuku ana, e whakapakeke ana hoki, ka hangaia e te RDP he kiriata pūmua waro ōrite e uru ana, e takai ana i waenga i ngā hua whakamakuku sima me ngā whakakī, e whakakī ana i ngā pūwero, e whakapakari ana hoki i te hononga ā-kanohi. Ko te "hanganga hiato waro-kore" i hangaia me ngā here waro-kore e hangai ana ki te sima ka whakapakari i te hononga i waenga i ngā taera me te papa. He tino whai hua tēnei ina tāpirihia ngā taera vitrified iti-te-mimiti wai, ngā taera nui rānei.
2. Ngāwari me te Ātete ki te Pakaru
He pakarukaru ngā hononga moata sima tuku iho, ā, he ngāwari ki te pakaru nā te piki me te heke o te pāmahana o te papa. Ka hangaia he kiriata e te polymer i roto i te RDP, e whakarato ana i te ngāwari me te ngāwari ki te piri taera. Ina paku pakaru te papa, ka ārai te papa piri i te ahotea, ka ārai i ngā pakaru. He mea nui tēnei mō ngā tono o waho, ngā taera papa nui, ngā pūnaha whakamahana papa rānei, e ngāwari ana ki te horapa me te whakaheke wera.
3. Te Ātete Wai me te Ātete Huka-Maehe Kua Whakapaitia
He maha ngā wā ka whakamahia ngā piripiri tāera i roto i ngā taiao makuku, i ngā taiao rānei e rerekē ana te pāmahana, pērā i ngā kaukau, ngā kīhini, me ngā mata o waho. Ahakoa ka taea e ngā mea here sima parakore te ngoikore, te pakaru rānei ina pāngia e te wai, ka whakaitihia e te hanganga hanga kiriata o te RDP te urunga wai, ka whakarei ake i te whai huatanga o te ārai wai. Ka whakapai ake hoki te RDP i te ātete huka-rewa o ngā piripiri tāera. Ahakoa ngā huringa huka-rewa maha, ka mau tonu te hanganga pumau me te piri o te paparanga piripiri, ka roa ake te ora o ngā whakaotinga tāera.
4. Te Whakapai Ake i te Mahi Taupānga
Ehara i te mea ka whakarei ake te RDP i ngā āhuatanga ā-pūkaha o ngā piri taera anake, engari ka arotau hoki i te wheako tono. Mā tōna horapa matūriki ka pai ake te hinu me te pupuri wai i muri i te whakaranu, ka roa ake te wā tuwhera, ā, ka nui ake te wā e taea ai e ngā kaiwhakauru te whakatika me te whakanoho i ngā taera. Ka whakarei ake hoki te RDP i te mahi me te thixotropy o ngā piri taera, kia māmā ake ai te tono, kia whakaitihia ai hoki te tūponotanga o te poka me te tihore.
5. Te Whakapai Ake i te Pumautanga me te Āhuatanga Urutau
Ko te roa o te mahi a ngā piripiri taera e whakawhirinaki ana ki tō rātou ngāwari ki ngā huringa taiao. He pai te ātete a te RDP ki te huarere, ki te kawakore, me te koroheketanga, me te pupuri i te mahi pumau ahakoa i raro i te hihi UV, i ngā rerekētanga o te haumākū, me ngā taiao waikawa me te kawakore. Hei tāpiri, he pai ake ngā piripiri taera kua whakarerekētia e te RDP mō ngā momo papa, pērā i te raima, te papa gypsum, me te moata sima, e whakawhānui ake ana i te whānuitanga o ā rātou tono.
6. Te Hiranga o te Taiao me te Penapena Pūngao
I te whanaketanga o te hoahoanga matomato, kei te whakakapi haere ngā piripiri taera i ngā tikanga tāutanga moata sima tuku iho. Mā te whakamahinga o te RDP ka taea e ngā piripiri taera te hono pai ki ngā paninga angiangi, ka whakaitihia te whakapaunga rauemi me te hanga i tētahi tukanga hanga ma, pai ake hoki mō te taiao. Ehara i te mea ka whakaitihia te whakapaunga pūngao me ngā utu anake, engari ka hangai anō hoki ki ngā au hanga hou e penapena pūngao ana, e pai ana mō te taiao.
Te tūranga matua o te RDP i roto i ngā piripiri taeraKo te whāinga matua he whakapakari i te kaha o te hononga, he whakapai ake i te ngāwari me te ātete ki te pakaru, he whakapakari i te ātete ki te wai me te huka-rewa, he whakapai ake i te mahi, me te whakapakari i te roa me te atawhai ki te taiao. Mā te hanga i tētahi hanganga whakakotahi me ngā hua whakamakuku sima, ka tino whakapai ake i te mahi whānui o ngā piripiri taera, ka taea ai e rātou te whakatutuki i ngā whakaritenga hanganga kaha-teitei, nui, me te uaua o ngā whare hou. Nō reira, kua noho te RDP hei wāhanga matua e kore e taea te whakakapi i roto i ngā hanganga piripiri taera.
