I roto i ngā pūnaha rauemi hanga whare hou, he mea nui te paura putty mō te whakataurite i te pakitara me te whakaotinga mata. Ka pā tika tōna mahi ki te kounga me te pakari o ngā paninga, ngā whakaotinga rānei o muri mai. Ko te ātete wai he tohu matua mō te kounga o te putty. He maha ngā wā ka hangaia te putty tuku iho i runga i ngā here kore-waro (pēnei i te raima kotakota, te pungarehu rere rua, me te sima). Heoi, nā tōna pakarukaru me te kore e piri, ka memeha haere ina pa ki te wai, ka uaua ki te whakatutuki i ngā whakaritenga o te whakamahinga roa ki ngā pakitara o roto, o waho hoki. Mā te tono opaura pūmua ka taea te whakamarara anō (RDP), kua tino pai ake te mahi whānui o te putty, inā koa tōna ātete ki te wai.
1. Ngā Āhuatanga Taketake o te RDP
He paura rehu-maroke te RDP kua hurihia hei paura totoka ka taea te whakamarara anō. Ina pā ki te wai, ka whakapūmau anō, ka whakahokia mai ngā āhuatanga taketake o te paura. Ko te nuinga o te mea he kapia polymer taumaha-rahi, he colloid tiaki, me ngā tāpiringa. Nā ōna āhuatanga hanga kiriata pai, ngāwari, me te piri, he whānuitia te whakamahinga i roto i ngā rauemi hanga pēnei i te moata ranunga maroke, te piripiri taera, me te paura putty.
2. Ngā Take mō te Ātete Wai Kino o Putty
He pakarukaru ngā papa kore-waro: Ka puta he ngatata mimiti i muri i te whakamakuku i te putty raima-raima, te putty sima rānei, ka hua ake he hanganga wewete, ka ngawari hoki te uru o te wai.
Te Piringa Kore e Rawa: He ngoikore te hononga ā-kanohi i waenga i te putty me te pakitara turanga me te paninga, ā, ka ngawari te pupuhi me te taka atu i ngā taiao makuku, i roto rānei i te wai.
Teitei o te Porowhita: He iti te matotoru o te paura putty tuku iho, ā, he maha ngā uaua toto, kia māmā ai te uru o te wai, kia pakaru ai.
Nō reira, kāore e taea e te whakawhirinaki anake ki ngā mea here kore-ora te kī taurangi i te ātete wai o te putty mō te wā roa. Me whakarerekē ki ngā polymers pēnei i te RDP.
3. Te Tikanga Whakapai Ake a te RDP i te Ātete Wai o te Putty
3.1. Pānga Hanga Kiriata
I muri i te whakamararatanga o te RDP ki roto i te wai i roto i te putty, ka hangaia he kiriata polymer tonu i te wā e whakapakeke ana, ka takai ōrite i ngā matūriki kore-waro. Ka whakaitihia e tēnei te porosity o roto o te putty, ā, ka whakaitihia te uruhanga wai.
3.2. Te Piringa Whakarei Ake
Ka uru te kiriata pūmua ki roto i ngā pūwero iti o te paparanga turanga, ka hanga he pānga "hononga ā-tinana me te hononga matū" e rua. Mā tēnei ka whakapakari i te piri i waenga i te putty me te papa, ka ārai i tōna hinganga ahakoa i roto i ngā taiao makuku.
3.3. Ngāwari me te Ātete ki te Kapiti
He ngāwari te pakaru o te putty nā te mimiti, nā te piki me te heke o te pāmahana me te haumākū, ā, ko ngā pakaru te ara nui mō te tomo mai o te makuku. Mā te RDP ka tino ngāwari te putty, ka whakamararatia te ahotea me te whakaiti i te hanganga o ngā pakaru, ka whakapai ake i te ātete wai.
3.4. Te Pūkenga Ārai-Paura Kua Whakapaitia
Ka ngāwari te paura o te pāreti raima-raima tuku iho ina pāngia e te wai. Heoi, ko te anga polymer i hangaia e te RDP i roto i te pāreti ka tino whakapakari i tōna pumau hanganga, ka ārai i te paura i puta mai i te waikura.
4. Ngā Pānga o te RDP i roto i te Putty Ātete-Wai
Kua Tino Pai Ake te Ātete Wai: Kua whakaatuhia e ngā whakamātautau he pai te āhua o te mata o te putty kei roto te nui o te RDP i muri i te 24 hāora o te rumakina ki te wai, ā, kāore he pupuhi, he kiri rānei e kitea ana. Kua Pai Ake te Āhua Mahi: Ka nui ake te hinu whakahinuhinu me te pupuri wai o te putty mā te RDP, kia maeneene ake ai te whakamahinga me te ngāwari ake o te whakamahinga.
Whānui ake te Whakamahinga: He pai te putty kua whakakiia ki te RDP mō ngā taiao maroke o roto, engari mō ngā wāhi makuku pērā i ngā kīhini, ngā kaukau, me ngā rūma o raro, tae atu ki te putty pakitara o waho.
Roa te Ora Ratonga: Ka ātete te putty ātete-wai ki te horomitanga makuku mō te wā roa, ka roa ake te mau o ngā pūnaha whakaoti pakitara me te whakaiti i ngā utu whakatika i muri mai.
5. Ngā Taunakitanga mō te Inenga me te Tauwehenga RDP
Ko te horopeta RDP e taunakitia ana i roto i ngā hanganga putty he 3%-5% te tikanga (i runga i te taumaha o te paura putty). Me whakarerekē te nui motuhake i runga i te momo putty, ngā āhuatanga o te papa, me te taiao tono:
He parapara pakitara o roto noa: Tata ki te 3% e ranea ana hei whakatutuki i ngā whakaritenga ātete wai taketake;
Pāreti ki te kīhini me te kaukau: 4%-5% te tūtohu hei whakapakari i te ātete wai me te piri;
Putty pakitara o waho e ātete ana ki te huarere: Ka taea te whakanui ake i te horopeta kia tika ai te ātete ki te ua me te piki me te heke o te pāmahana me te makuku. He mea nui kia mōhio he utu nui te RDP, ā, ko te tāpiri nui rawa ka raru pea te ōhanga, ā, ka whakaiti pea i te pakeke o te putty. Nō reira, me whakaaro ki te whakapai ake i te mahi me te utu.
RDPHe mahi nui tā te putty ki te whakapai ake i te ātete wai o te putty. Mā te hanga i tētahi kiriata, te whakarei ake i te piri, me te whakapai ake i te ngāwari me te ātete pakaru, ka aro pai te RDP ki te raruraru o te pakaru me te maturuturu o te putty tuku iho ina pāngia e te wai. Mā tēnei ka taea e te putty te whakatutuki i ngā whakaritenga o te whakapaipai pakitara o roto, engari ka mau tonu hoki te pumau i roto i ngā taiao makuku me waho. Mā te whakamahinga tika o te RDP, ehara i te mea ka whakapai ake i te ātete wai me te roa o te mahi o te putty, engari ka whakatairanga hoki i te whanaketanga o ngā rauemi whakapaipai whare mahi-teitei, roa-te-roa.
