Ngā paura pūmua ka taea te whakamarara anō (RDP)He tāpiringa nui ēnei i roto i ngā hanganga moata maroke e whakamahia ana puta noa i ngā tono hanga maha, tae atu ki ngā piripiri taera, te putty pakitara, ngā matū whakataurite-ake, me ngā pūnaha whakaoti whakamahana o waho (EIFS). Ka hangaia ēnei paura polymer mā te whakamahi i ngā emulsions polymer whakamaroke-rehu, ka puta he paura rere-kore e marara ana ki te wai hei hanga anō i te rapa taketake. Ka whakapai ake te RDP i ngā āhuatanga matua pēnei i te ngāwari, te piri, te ātete pānga, me te pupuri wai. Heoi, ko te whiriwhiri i te RDP tika me mārama ki te hanganga matū me te mahi mahi o ngā momo rerekē e wātea ana i te mākete.
1. Ngā Wāhanga Matua o te RDP
Ko ngā paura pūmua ka taea te whakamarara anō he mea tito mai i ēnei e whai ake nei:
Pūtake pūmua: Ko te rauemi pūmua matua, ko te vinyl acetate-ethylene (VAE), ko te vinyl acetate-acrylic (VAc-Acr), ko te styrene-butadiene (SBR), ko te ethylene-vinyl chloride rānei (EVA).
Koroiti tiaki: He waipiro polyvinyl (PVA) te nuinga o te wā, e whakakōpiri ana i ngā matūriki i te wā e whakamaroke ana, ā, e whakau ana i a rātou ki roto i te wai.
Ngā Tāpiringa: Ka tāpirihia pea ngā mea ārai-kōpiri pēnei i te māngaro ether, ngā whakakī kohuke rānei hei whakapai ake i te pumau o te rokiroki me te rere o te wai.
2. Ngā momo RDP me ō rātou āhuatanga
2.1. Ngā Copolymers Vinyl Acetate-Ethylene (VAE)
Ngā Āhuatanga: Te piri taurite, te ngāwari, me te ātete ki te wai.

2.4. Ngā Copolymers Ethylene-Vinyl Chloride (EVA)
Ngā Āhuatanga: He tino ngāwari, he ātete hoki ki te wai.
Ngā Whakamahinga: Ngā piripiri taera motuhake, ngā matū whakatika, ngā paninga ātete wai.
Ngā Painga:
He ātete matū pai ake.
Te whakapai ake i te piri i roto i ngā taiao uaua.
3. Ngā Paearu mō te Kōwhiri i te RDP Tika
3.1. Ngā Whakaritenga Tono
Ko te whakamahinga whakamutunga e whakatau ana ko ēhea ngā āhuatanga tino nui:
He nui te piri o ngā piripiri taera me te ātete ki te paheke.
E hiahiatia ana e te EIFS te ngāwari me te ātete ki te huarere.
Me ngāwari te rere o ngā matū whakataurite-ake, me whakaiti hoki i te mimiti.
3.2. Hototahitanga o te Papatūānuku
Whakaarohia te rauemi turanga (raima, gypsum, pereki, me ētahi atu) me te pānga ki te taiao. Mō ngā papa kore-pūwero, maeneene rānei, ko te RDP me ngā āhuatanga piri pai pēnei i te SBR te mea e pai ake ana.
3.3. Ngāwari me te Manawanui ki ngā Hurihanga
Ko ngā pūnaha, ngā hanganga rānei o waho e pāngia ana e ngā huringa wera, me whai RDP teitei me te roa me te ngāwari (hei tauira, EVA, SBR rānei).
3.4. Te Pupuri Wai me te Āheinga Mahi
Mā te tāpiri o te RDP ka pai ake te pupuri wai, he mea nui i ngā āhuarangi wera, maroke rānei. Ko ngā momo VAE ka whakapai ake i te mahi me te wā tuwhera.
3.5. Te Mahi Ā-Mīhini
Ka pā te RDP ki te kaha kume, te ātete pānga, me te ātete pakū. Tīpakohia i runga i ngā āhuatanga o te pikaunga, o te kakahu rānei.
3.6. Te Pumau o te Taiao
Mō ngā whakamahinga o waho, he mea nui te ātete ki te UV, te pumau o te kawakore, me te ātete ki te wai. He pai ake te whakamahi i te kiriaku, i te EVA RDP rānei mō ēnei āhuatanga.
4. Te wehewehe i te RDP i roto i te Mahi
Ahakoa i roto i te momo pūmua kotahi, kei reira tonu ngā rerekētanga i runga i:
Te pāmahana whakawhiti karāhe (Tg): Ko te iti o te Tg ka hua ake he kiriata ngohengohe, he ngāwari ake. Ko te teitei o te Tg ka puta he pakari me te mārō ake.
Rahi o te matūriki: Ka pā ki te tere marara me te mutunga o te mata.
Te nui o te pūmua (%): E tohu ana i te rauemi hohe; ko te nui ake o te nui e tohu ana i te pai ake o te mahi engari ko te nui ake o te utu.
Pāmahana hanga kiriata: Ka hanga kiriata ngā pūmua MFFT iti (pāmahana hanga kiriata iti rawa) i ngā āhuatanga taiao, he mea nui mō ngā āhuarangi makariri.
5. Te Whakamātautau Mahi me ngā Tohu Kounga
I te aromatawai, i te whakataurite rānei i te RDP, ko ēnei whakamātautau e whakamahia whānuitia ana:
Whakamātautau marara anō: Mā te whakamātautau ka taea te marara anō te paura ki roto i te wai.
Kaha here (piripiri kume): Inehia i mua atu, i muri hoki i te koroheketanga, i te rumakina rānei ki te wai.
Te kaha piko me te kaha pēhi: Ka aromatawai i ngā whakapainga hanganga i roto i ngā moata.
Ātete ki te mimiti me te ngatata: He mea nui mō ngā moata whakatika, mō ngā tono paparanga angiangi rānei.
Te ngāwari o te mahi me te wā tuwhera: Ka arotake i te whakamahinga i ngā papa mahi.
6. Taurite Utu me te Mahi
Ahakoa he pai ake ngā āhuatanga o ngā paura RDP mahi-teitei pērā i te EVA, te SBR rānei, he nui ake te utu. Mō ngā tono e aro nui ana ki te utu, he pai te whakataurite a ngā paura VAE paerewa. Mā te whakaranu i ngā momo rerekē ka taea hoki te whakapai ake i te mahi me te whakahaere i ngā whakapaunga.
Ko te whiriwhiri i te paura pūmua ka taea te whakamarara tika he taurite rautaki o te mahi hangarau, te pai o te taiao, me te whai hua o te utu. Mā te mārama ki te hanganga matū, ngā āhuatanga miihini, me ngā hiahia motuhake o te tono ka taea e ngā kaihanga te whiriwhiri i te paura tino pai.RDP mō ā rātou moata, hua hanga rāneiI te mea e piki haere ana te hiahia o te umanga hanga ki ngā rauemi e whai hua ana, e pumau ana, e ngāwari ana hoki ki te whakamahi, kei te whānui haere tonu te tūranga o te RDP—nā reira ka nui ake te hiranga o te kōwhiringa me te rerekētanga tika i mua.
