Paura pūmua ka taea te whakamarara anō (RDP), hei tāpiringa rauropi matua i roto i ngā mota ranunga maroke hou, e whakamahia whānuitia ana i roto i ngā pūnaha maha pērā i ngā piripiri taera, ngā paura putty, ngā mota whakamarumaru pakitara o waho, ngā mota whakataurite-ake, me ngā mota ā-wai nā te mea he pai rawa ngā āhuatanga piri, te ngāwari, me ngā āheinga whakarerekē. Ko te tikanga, he paura totoka i hangaia mā te whakamaroke i te emulsion polymer. Ina pā ki te wai, ka taea te marara anō hei emulsion pumau, ka hanga he kiriata polymer rauropi tonu i te wā o te tukanga whakapakeke mota, ka whakapai ake i te mahi whānui o te mota.
1. Te Tikanga Matua o te RDP hei Whakapai ake i te Mahi o te Moata
1.1. Te Whakapai Ake i te Kaha o te Hononga
He tino piri te kiriata pūmua i hangaia e te RDP i muri i te whakapakeketanga o te moata, ā, he pai te ngāwari o te hanga, ka hanga he piriti hononga kaha ki te mata o te papa, ka whakapai ake i te piri i waenga i te moata me ngā rauemi pēnei i te raima, ngā pereki, ngā papa EPS, me ngā taera. He mea tino nui te mahi a te RDP ki ngā papa iti te mimiti, ki ngā papa maeneene rānei.
1.2. Ngāwari me te Ātete Ngatata Kua Whakapai Ake
He tino pakarukaru ngā rauemi sima tuku iho, ā, he ngāwari ki te pakaru nā te huringa pāmahana me te whakarerekētanga o te papa. Ka marara te pūmua i roto i te RDP ki roto i ngā pūwero o te moata, ka hanga he hanganga whatunga ngāwari, ka whakaiti i te kaha o te rauemi, ka whakanui ake i tōna ātete ki te whakarerekētanga, ā, ka tino whakapai ake i te ātete pakaru o te moata.
1.3. Te Whakapai Ake i te Āhua Mahi
Mā te RDP ka pai ake te mahi me te maeneene o te moata, ka pai ake te āhua o te mahi me te whakamahinga. Mā te pupuri wai pai ake me te roa o te wā tuwhera ka pai ake te hanganga, ka piki ake te pai me te pumau o te kounga.
1.4. Te Ātete ki te Wai me te Huarere Kua Whakapai Ake
He tino pai te ātete wai o te kiriata pūmua me te ātete wai, ka whakaiti i te mimiti wai o te moata, ā, ka whakapai ake i te ātete ki te makuku me te huringa huka-rewa. I roto i ngā tono pakitara o waho, ka āwhina te RDP ki te whakapai ake i te ātete huarere o ngā paninga me ngā moata, me te pupuri i tō rātou pumau i raro i te whakaaturanga roa.
2. Ngā Whakamahinga o te Pūmua Whakamarara Anō (RDP) i roto i ngā Pūnaha Moata Rerekē
2.1. Piripiri Tāera
He wāhanga nui te RDP o te piripiri taera, e whakapai ake ana i te piri, i ngā āhuatanga ātete-paheke, me te ngāwari. Mō ngā taera rahi, ngā taera iti-mimiti, ngā taera whakakoi rānei, mā te RDP ihirangi pūmua teitei ka mau te hononga, ā, ka ārai i ngā wāhi takoto kau me te wetewete.
2.2. Mota Whakamarumaru Pakitara o Waho (Pīpiri EPS/XPS, Mota Whakaoti)
I roto i ngā pūnaha whakamarumaru, ka whakaratohia e te RDP te ngāwari me te kaha o te here e tika ana, e āhei ai te moata ki te piri pūmau ki ngā papa EPS/XPS. Ka whakapai ake hoki i te ātete ki te pakaru me te ātete pānga o te paparanga whakaoti, kia mau ai te pumau mō te wā roa o te pūnaha whakamarumaru.
2.3. Moata Ārai Wai
Ka hangaia e te RDP he kiriata pūmua matotoru i roto i te moata, ka whakaiti i te porosity o ngā capillaries me te whakapai ake i te ātete wai. Mā te mahi tahi me ngā hua whakamakuku sima, ka tino whakarei ake i te ngāwari me te pakari o te paparanga ātete wai.
2.4. Mota Whakatakoto-ā-Iho
I roto i ngā pūnaha whakataurite-ake, ka whakapai ake te RDP i te kaha wawe, te rere, me ngā āhuatanga piri o te moata, me te whakaiti hoki i te pakarukaru, ka hua ake he hanganga papa pumau ake, he kaha ake hoki te mata.
2.5. Paura Whakapūkara
Mā te tāpiri i te RDP ki te paura putty ka whakarei ake i te piri, ngā āhuatanga ārai-kirikiri, me te āhua kirikiri, ka hua ake he mata pakitara maeneene ake, he pai ake hoki te ātete ki te wai me te roa.
2.6. Kaihoko Whakatika Moata me te Atanga
Ka whakapai ake te RDP i te ātete ki te piri me te ngatata o ngā rauemi whakatika, kia pumau ake ai, kia pono ake ai hoki i roto i ngā tono pēnei i te whakatika raima tawhito me te maimoatanga atanga.
3. Ngā Whakatūpato mō te Whakamahi i te Paura Pūmua Whakamarara Anō
Kōwhiria te mea e tika anaRDPte momo me te horopeta i runga i te mahi a te pūnaha moata;
Mā te whakakotahi me ngā etera cellulose (HPMC/MHEC), ngā etera māngaro, me ētahi atu, ka taea te whakapai ake i te pupuri wai, te ngāwari o te mahi, me te ātete ki te totohu;
Penapena ki te wāhi maroke kia kore ai e makuku, e piri rānei;
Kia tino marara te ranunga i te wā e whakaranua ana kia pumau ai te mahi.
