Nā Resin Hana ʻia
Hoʻopili ka maleic anhydride me nā polyols (a ukali ʻia e ke keʻa ʻana me ka styrene) e hana i nā resins polyester unsaturated (UPR), kahi resin thermosetting. Ua māhele ʻia ʻo UPR i nā plastics i hoʻoikaika ʻia e ka fiber (FRP, i ʻike nui ʻia ʻo ka plastic fiberglass-reinforced) a me nā plastics i hoʻoikaika ʻole ʻia.
Hoʻohana ʻia ka FRP i ke kūkulu ʻana (e like me nā pepa corrugated, nā hale i hana mua ʻia, nā loko wai, nā lumi ʻauʻau, nā pahu wai ʻino), ka hana ʻana (e like me nā ʻaoʻao waho o ka moku/kaʻa, nā mea hoʻonaninani o loko, nā ʻauʻau, nā puka/puka makani, nā papa insulation uila), ka ʻenekinia kemika (e like me nā paipu, nā pahu mālama, nā lako kaiapuni), a me nā waiwai kūʻai (e like me nā koʻokoʻo lawaiʻa, nā raketa, nā papa hau, nā kalapu kolepa, nā mahiole palekana).
Hoʻohana ʻia ka UPR i hoʻoikaika ʻole ʻia i loko o ka sima polyester, nā mea hoʻopaʻa, nā uhi ʻili (piano, lako hale), nā pihi, a me ke kinikini/onyx hana ʻia.

ʻO kā mākou maleic anhydride e haʻaheo nei i nā pae haumia haʻahaʻa loa a me ke kūpaʻa wela kūikawā—kūpono no ka hoʻoikaika ʻana i ka hana o kāu polyesters unsaturated a me nā uhi. Kaomi e kūkākūkā no nā hoʻonā lako i hana kūikawā ʻia i kēia manawa!
