Ngā Resin Hangai
Ka tauhohe te maleic anhydride ki ngā polyol (ā, muri iho ka honoa ki te styrene) hei hanga i ngā kapia polyester kāore i te mākū (UPR), he kapia thermosetting. Kua wehea te UPR ki ngā kirihou whakakaha-muka (FRP, e mōhiotia whānuitia ana ko te kirihou whakakaha-muka karāhe) me ngā kirihou kāore i te whakakaha.
E whakamahia ana te FRP i roto i ngā mahi hanga (hei tauira, ngā pepa kowakawaka, ngā whare kua oti te hanga, ngā puna kaukau, ngā wharepaku, ngā tāke wai para), te mahi hanga (hei tauira, ngā āhua o waho o te kaipuke/waka, ngā whakapaipai o roto, ngā kaukau, ngā tatau/matapihi, ngā papa whakamahana hiko), te hangarau matū (hei tauira, ngā paipa, ngā tāke rokiroki, ngā taputapu taiao), me ngā taonga kaihoko (hei tauira, ngā tokotoko hī ika, ngā raketi, ngā papa hukarere, ngā karapu korowha, ngā potae haumaru).
E whakamahia ana te UPR kāore i whakakahangia ki roto i te raima polyester, ngā mea here, ngā paninga mata (piana, tāonga whare), ngā pātene, me te māpere/ōnika horihori.

He tino iti te poke o tā mātou anhydride maleic, ā, he tino pumau te pāmahana—he tino pai mō te whakanui ake i te mahi a ō polyesters me ō paninga kore mākū. Pāwhiritia hei kōrero mō ngā otinga tuku kua whakaritea inaianei!
