Kei te whanake tonu te umanga hanga whare ki ngā rauemi hanga whare he pai ake te mahi, he pai te penapena pūngao, he pakari hoki. He maha ngā wā ka pāngia ngā rauemi sima tuku iho e ngā ngoikoretanga pēnei i:

• Ngāwari iti
• Te piri ngoikore
• Te pakarukaru nui
• Ngā raruraru pakaru
• Ātete wai ngoikore

Hei whakakore i ēnei wero, kei te piki haere te whakamahi a ngā hanganga moata ranunga maroke hou i ngā tāpiringa polymer matatau. I roto i ēnei,Paura Pūmua Whakamarara Anō (RDP)kua riro hei tetahi o ngā rauemi mahi tino nui.

He paura pūmua motuhake te RDP, ka taea te marara anō ki te wai, ka hanga anō i tētahi emulsion pūmua pumau. Ina tāpirihia ki ngā pūnaha sima, ka hangaia e te RDP he kiriata pūmua ngāwari e whakapai ake ana i:

• Te kaha o te piri
• Ngāwari
• Ātete pakaru
• Ātete wai
• Te pakari

I ēnei rā, e whakamahia whānuitia ana te RDP i roto i:

• Ngā piripiri tāera
• Ngā pūnaha whakaoti whakamahana o waho (EIFS)
• Putty pakitara
• Ngā matū whakaōrite-ake
• Whakatikatika mōta
• Ngā moata waikore
• Ngā rauemi e hangai ana ki te gypsum

1. Te Mārama ki te Paura Pūmua Whakamarara Anō (RDP)

1.1 He aha te RDP?

Ko te Paura Pūmua Whakamarara Anō he paura rere noa i hangaia mā te whakamaroke rehu i ngā whakamomona pūmua.

Ko te tukanga hangahanga ko te tikanga whānui:

1. Te whakarite i te emulsion polymer
2. Whakamaroke rehu
3. Tāpiritanga colloid tiaki
4. Whakapūmautanga paura

Ina pā te paura RDP ki te wai, ka tohatoha anō hei matūriki pūmua, ā, ka hangaia anō he emulsion.

Ehara te RDP i te matū kotahi. He pūnaha pūmua e hangai ana ki ngā momo kapia rerekē.

Ko ngā momo pūmua noa ko:

• Te winira acetate etilena (VAE)
• Homopolymer acetate vinyl
• Ngā pūmua kiriaku
• Ngā pūmua styrene-acrylic

3.1 Tikanga Whakamarara Anō

Ina tāpirihia te RDP ki roto i te moata:

Hipanga 1:

Ka marara ngā matūriki paura ki roto i te wai whakaranu.

Hipanga 2:

Ka tohatoha ōrite ngā matūriki polymer.

Hipanga 3:

I te wā whakamaroke, ka hanumi ngā matūriki polymer.

Hipanga 4:

Ka hangaia he kiriata pūmua tonu i roto i te hanganga moata.

3.2 Te Hanganga Kiriata Pūmua

Ka hangaia e te kiriata pūmua he whatunga ngāwari i waenganui i:

• Ngā matūriki sima
• Ngā Whakakotahitanga
• Ngā Whakakī

Ka whakapai ake tēnei whatunga i te mahi whānui o te moata.

4. Ngā Mahi Matua o te RDP i roto i ngā Rauemi Hanga

4.1 Te Whakapai Ake i te Kaha o te Piripiri

Ko tētahi o ngā mahi tino nui o te RDP ko te whakapai ake i te mahi here.

Ka whakarei ake te RDP:

• Te piri ki te raima
• Te kaha o te here ki ngā taera
• Te pumau o te atanga

Ripanga 3: Whakapai ake i te piri mā te RDP

4.2 Te Whakanui Ake i te Ngāwari

He pakarukaru noa iho ngā rauemi sima. Ka taea e ngā huringa pāmahana me te nekehanga o te whare te hanga ahotea.

Ka whakaratohia e te RDP te ngāwari mā te waihanga i tētahi whatunga pūmua ngāwari.

Ngā Painga:

• Te whakaiti i te pakaru
• He pai ake te ātete ki te whakarerekētanga
• Te roa o te mau

4.3 Te Whakapai Ake i te Ātete ki te Pakaru

Ka puta ngā pakaru nā:

• Te whakahekenga
• Ngā huringa pāmahana
• Te ahotea ā-mīhini
