Ko ngā paura pūmua ka taea te whakamarara anō (RDP) he ranunga matatini o ngā pūmua me ngā tāpiringa e whakamahia whānuitia ana i roto i ngā rauemi hanga, inā koa i roto i te hanga mota ranunga maroke. He mea nui ēnei paura ki te whakapai ake i te mahi me ngā āhuatanga o ngā momo rauemi hanga pēnei i ngā piripiri taera, ngā grout, ngā matū whakataurite-ake me ngā pāreti sima.
Ngā wāhanga matua:
Pūtake pūmua:
Ethylene vinyl acetate (EVA): He mea whakamahi noa te copolymer EVA i roto i te RDP nā te mea he pai rawa atu ōna āhuatanga hanga kiriata, tōna piri, me tōna ngāwari. Ka taea te whakarerekē i te nui o te vinyl acetate i roto i te copolymer hei whakarerekē i ngā āhuatanga o te polymer.
Te Acetate Vinyl me te Ethylene Carbonate: I runga i ngā whakaritenga motuhake o te tono, ka whakamahia pea e ngā kaihanga te ethylene carbonate hei utu mō te vinyl acetate. Kua pai ake te ātete wai me te piri o te ethylene carbonate i roto i ngā āhuatanga makuku.
Kiriaku: Ko ngā pūmua kiriaku, tae atu ki ngā kiriaku parakore, ngā pūmua kopa rānei, e whakamahia ana mō tō rātou ātete ki te huarere, te roa, me te maha o ngā whakamahinga. E mōhiotia ana mō te whakarato piri pai ki ngā momo papa.
Koroiti tiaki:
Hydroxypropyl methylcellulose (HPMC): He colloid tiaki te HPMC e whakamahia whānuitia ana i roto i te RDP. Ka whakapai ake i te kaha o te horapa anō o ngā matūriki polymer, ā, ka whakarei ake i ngā āhuatanga whānui o te paura.
Waipiro Polyvinyl (PVA): Ko te PVA tētahi atu colloid tiaki e āwhina ana i te pumau me te marara o ngā matūriki polymer. He mahi anō hoki tāna ki te whakahaere i te matotoru o te paura.
Kaiwhakaahua kirihou:
Dibutyl Phthalate (DBP): Ko te DBP tētahi tauira o te plasticizer e tāpirihia ana ki te RDP hei whakapai ake i te ngāwari me te ngāwari ki te tukatuka. Ka āwhina i te whakaiti i te pāmahana whakawhiti karāhe o te polymer, kia ngāwari ake ai.
whakakī:
Konupūmā Kāponāte: Ka taea te tāpiri i ngā whakakī pēnei i te konupūmā kāponāte hei whakarei ake i te nui o ngā paura, hei huarahi hoki e whai hua ana ki te whakatika i ngā āhuatanga pēnei i te kakano, te pūngao me te mākūkū.
Ngā mea whakaū me ngā antioxidants:
Ngā Kaiwhakaū: Ka whakamahia ēnei hei ārai i te pirau o te pūmua i te wā e rongoa ana, e tukatuka ana hoki.
Ngā Ārai Matewai: Ka tiakina e ngā ārai matewai te pūhui mai i te pirau waikura, kia roa ai te ora o te RDP.
Ngā mahi a ia wāhanga:
Pūtake pūmua: Ka whakarato i ngā āhuatanga hanga kiriata, te piri, te ngāwari me te kaha ā-pūkaha ki te hua whakamutunga.
Te korōiti tiaki: Whakarei ake i te horapa anō, te pumau me te horapa o ngā matūriki pūmua.
Kaiwhakaahua: Ka whakapai ake i te ngāwari me te ngāwari o te tukatuka.
Ngā Whakakī: Whakatikatikahia ngā āhuatanga pēnei i te kakano, te pūngao, me te mākūkū.
Ngā mea whakau me ngā ārai mate: Ārai i te pirau o te pūmua i te wā e rongoa ana, e tukatuka ana hoki.
hei whakamutunga:
He wāhanga maha ngā whakamahinga o te paura pūmua ka taea te whakamarara anō (RDP) i roto i ngā rauemi hanga whare hou. Ko tōna hanganga matū, tae atu ki ngā pūmua pēnei i te EVA, te kapia kiriaku rānei, ngā koroid tiaki, ngā mea whakapūmau kirihou, ngā whakakī, ngā mea whakaū me ngā mea ārai-mate, kua āta hangaia kia tutuki ai ngā whakaritenga motuhake o ia tono. Mā te whakakotahitanga o ēnei wāhanga ka āwhina i te whakapai ake i te kaha ki te whakamarara anō i te paura, te kaha here, te ngāwari me te mahi whānui i roto i ngā hanganga moata ranunga maroke.
