Tikanga Whakamātautau Kounga o te Paura Polymer Whakamarara Anō

He mea nui te whakamātautau kounga o te paura pūmua ka taea te whakamarara anō (RDP) kia tutuki ai ngā paerewa me ngā whakaritenga e hiahiatia ana mō ngā momo tono, pērā i ngā rauemi hanga pēnei i ngā piripiri taera, ngā moata, me ngā kiriuhi ārai wai. Anei ētahi tikanga whakamātautau kounga noa mō te paura pūmua ka taea te whakamarara anō:

1.Tātaritanga Rahi MatūrikiKa pā tika te tohatoha rahi o te matūriki ki te mahi a te RDP e pā ana ki te mararatanga, te hanganga kiriata, me ngā āhuatanga hangarau. Ka taea te whakamahi i ngā tikanga diffraction laser, te whakapūtātanga, te karuārai rānei hei ine i te tohatoha rahi o te matūriki o te RDP.

2.Te Kīanga PapatipuHe tawhā nui te mātotoru papatipu e pā ana ki te whakahaere, te kawe, me te whakaranu i ngā āhuatanga o te RDP. I te nuinga o te wā ka inehia mā te whakakī i tētahi rōrahi e mōhiotia ana o te RDP ki roto i tētahi ipu, me te ine i tōna taumaha. Kātahi ka tatauhia te mātotoru papatipu mā te wehewehe i te taumaha ki te rōrahi.

3.Ihirangi PūmauKo te nui o te totoka o te RDP e pā ana ki te ōrau o ngā totoka polymer i roto i te paura. I te nuinga o te wā ka whakatauhia mā te whakamaroke i te taumaha e mōhiotia ana o te RDP i te pāmahana kua tohua, kātahi ka ine i te taumaha e toe ana. Ka tatauhia te nui o te totoka i runga i te taumaha kua ngaro i te wā whakamaroke.

4.Te Pāmahana Whakawhiti Karāhe (Tg)Ko te Tg o te RDP he tohu mō tōna pumau wera, ā, he pānga ki ngā āhuatanga rokiroki me te tukatuka. Ka taea te whakamahi i te calorimetry matawai rerekētanga (DSC) te tātaritanga miihini hihiri rānei (DMA) hei whakatau i te Tg o te RDP.

5.Te matotoru o te mararatanga o te RDPHe mea nui te matotoru o te mararatanga RDP mō ōna āhuatanga tono, pērā i te ngāwari o te mahi, te wā tuwhera, me te ātete ki te totohu. Ka taea te ine mā te whakamahi i te viscometer, i te rheometer rānei i raro i ngā āhuatanga kutikuti whakahaeretia.

6.Te Hanga Kiriata me te PiringaHe mea nui te kaha hanga kiriata me te kaha piri o te RDP mō tōna mahi i roto i ngā rauemi hanga. Ka taea te whakamahi i ngā tikanga pēnei i ngā whakamātautau hanganga kiriata, ngā whakamātautau piri kiri, me ngā whakamātautau kume hei aromatawai i ēnei āhuatanga.

7.Tātaritanga Hanganga MatūKa taea te whakamahi i ngā tikanga pēnei i te Fourier-transform infrared spectroscopy (FTIR) me te nuclear aukume resonance (NMR) spectroscopy hei tātari i te hanganga matū o te RDP me te whakarite i tōna ōritetanga me tōna parakore.

8.Whakamātautau Ātete WaiHe maha ngā wā ka whakamahia te RDP i ngā mahi e hiahiatia ana te ātete wai, pērā i ngā kiriuhi ārai wai. Ka taea te aromatawai i te ātete wai mā te whakahaere i ngā whakamātautau pērā i ngā whakamātautau rumaki wai, ngā whakamātautau tuku mamaoa wai rānei i runga i ngā rauemi kei roto ko te RDP.

Ko ēnei ētahi noa iho o ngā tikanga whakamātautau kounga e whakamahia ana mō te paura pūmua ka taea te whakamarara anō. I runga i ngā whakaritenga motuhake o te tono me ngā paerewa/ture e whai mana ana, tera pea ka hiahiatia ētahi atu whakamātautau hei whakarite i te kounga me te mahi a ngā hua RDP.
