Me pēhea te whakamātautau i te kounga o te RDP

Ko te Paura Pūmua Whakarewa-anō (RDP) he tūāpapa mō ngā rauemi hanga hou, e whakarei ake ana i te piri, te ngāwari, me te pakari i roto i ngā moata, ngā piripiri taera, me ngā mea whakairo. Heoi, mā te RDP kounga-kore ka arahi pea ki ngā pakaru kino pērā i te wehewehe, ngā kapiti, te heke rānei o te ātete wai.

Ngā Tawhā Matua hei Whakamātautau i te Kounga RDP

1. Ngā Āhuatanga Ā-tinana

• Te Tohatoha Rahi o te Matūriki
  He aha te hiranga: Ka pā ki te mararatanga me te hanganga kiriata.
  Tikanga whakamātautauTe whakarara taiaho (ISO 13320) te tātari tātari rānei.
  Awhe pai rawa atu: 80–120 maikorona mō te nuinga o ngā tono hangahanga.

• Te Kīanga Papatipu
  He aha te hiranga: Ka pā ki te tika o te inenga me te ōritetanga o te ranunga.
  Tikanga whakamātautauASTM B527 (ine rahinga).
  Awhe pai rawa atu: 400–600 kg/m³.

• Ihirangi Makuku Toenga
  He aha te hiranga: Ka piri te kai i te nui o te makuku, ā, ka iti ake te roa o te oranga.
  Tikanga whakamātautauTe inenga o Karl Fischer, te whakamaroke rānei i roto i te oumu (ISO 787-2).
  Awhe pai rawa atu:

2. Te Hanganga Matū

• Ihirangi Polymer
  He aha te hiranga: Ka whakatau i te kaha here o te RDP.
  Tikanga whakamātautauTātaritanga wera-moka (TGA) hei ine i te ihirangi waro, me te ihirangi kore-waro.
  Awhe pai rawa atu: 90–99% pūmua (ka rerekē i runga i te momo).

• Te Ihirangi o te Pungarehu
  He aha te hirangaKa whakaitihia te mahi e te nui o te pungarehu (ngā whakakī kohuke).
  Tikanga whakamātautauTe tahunga i te 1000°C (ISO 3451).
  Awhe pai rawa atu

• Uara pH
  He aha te hiranga: Ka pā ki te hototahitanga me ētahi atu tāpiringa (hei tauira, ngā cellulose ethers).
  Tikanga whakamātautaumita pH i roto i te wairewa 10%.
  Awhe pai rawa atu: 6.5–8.5.

3. Te Mahi i roto i ngā Taupānga Moata

• Kaha Here
  He aha te hirangaHe mea nui mō te piri ki ngā papa.
  Tikanga whakamātautauEN 1348 (ngā piripiri taera) ASTM C1583 rānei (ngā moata whakatika).
  Hua pai rawa atu: >1.0 MPa mō te nuinga o ngā tono.

• Kaha Whakapiko me te Kaha Pehi
  He aha te hiranga: Ka whakarite i te pumau o te hanganga.
  Tikanga whakamātautauEN 196-1 (whakamātautau sima).

• Ātete Wai
  He aha te hirangaĀrai i te ngoikore i ngā āhuatanga makuku.
  Tikanga whakamātautauRukuhia ki te wai mō ngā rā e whitu, kātahi ka whakamātauria te kaha o te piri.

• Wā Tuwhera
  He aha te hirangaMā te roa o te wā tuwhera ka pai ake te mahi.
  Tikanga whakamātautauTāpirihia te moata ki te papa i ētahi wā, ka ine i te ngaronga o te piri.

Ngā Pātai Auau

P: Ka taea e au te whakamātautau i te kounga o te RDP me te kore he taiwhanga?
A: Mā ngā whakamātautau taketake pēnei i te wairewatanga i roto i te wai (me marara anō te RDP pai) me ngā tirotiro tirohanga mō ngā puranga/te ōritetanga o te tae ka taea te whakarato i ngā māramatanga tere.

P: Kia pēhea te auau o te whakamātautau i te RDP?
A: Whakamātauria ia puranga ina tae mai, ā, i ia wā i te wā e rongoa ana (hei tauira, i ia 6 marama).

P: He pai ake te RDP mēnā he nui te ihirangi pūmua?
A: Kāore pea. Ko te momo pūmua (hei tauira, VA/VeoVA vs. kiriaku) me te hototahi ki tō hanganga te mea nui ake.
