He matū te matū whakaora epoxy e whakamahia ana hei whakaorangā kapia epoxymā te tauhohe matū ki ngā rōpū epoxy i roto i te kapia epoxy hei hanga i tētahi hanganga honohono-whiti, ā, ka waiho te kapia epoxy hei rauemi totoka mārō, pakari.
Ko te mahi matua a ngā matū whakaora epoxy he whakarei ake i te pakeketanga, te ātete ki te pakū, me te ātete matū o ngā kapia epoxy, kia roa ai te ora, kia pakari ai hoki, he wāhanga nui hoki o ngā mea hanga epoxy pultruded. E whakamārama ana tēnei tuhinga me pēhea te whiriwhiri i te matū whakaora epoxy tika i runga i ngā āhuatanga rerekē:
E ai ki ngā tikanga whakaora
- Te whakamaroke i te pāmahana rūma: Mena e hiahiatia ana he whakamaroke tere i te pāmahana rūma, ka taea te whiriwhiri i ngā kaihoko whakamaroke amine aliphatic pēnei i te ethylenediamine me te diethylenetriamine; ki te kore e hiahiatia kia tere te tere whakamaroke, me te arotahi ki te wā mahi, ka taea te whiriwhiri i ngā kaihoko whakamaroke polyamide.
- Whakamaroke wera: Mō te ātete wera nui me ngā āhuatanga miihini, ka taea te whakamahi i ngā kaihoko whakaora amine kakara, pērā i te diaminodiphenylsulfone (DDS), me ētahi atu,; mō te whakaora tere i te pāmahana iti, ka taea te whakaaro ki ngā kaihoko whakaora amine kua whakarerekētia me ngā whakatere.
- Te whakamaroke i raro i ngā āhuatanga motuhake: mō te whakamaroke i roto i te taiao makuku, ka taea te whiriwhiri i tētahi matū whakamaroke whakamaroke whakamaroke mākū; mō tētahi pūnaha whakamaroke mārama, ka taea te whiriwhiri i tētahi matū whakamaroke me te photoinitiator me te epoxy acrylate.
E ai ki ngā whakaritenga mahi
- Ngā āhuatanga miihini: mēnā e hiahiatia ana he pakeke me te kaha teitei, ka taea te whiriwhiri i ngā matū whakaora anhydride; mēnā e hiahiatia ana he ngāwari me te ātete pānga pai, he pai ake ngā matū whakaora uaua pēnei i te rapa polysulfide.
- Ātete matū: he nui ngā whakaritenga mō te ātete waikawa, kawakore, me te whakarewa,kapia phenoliche pai ake te whakamahi i te kaihoko whakaora, i tētahi atu kaihoko whakaora amine kua whakarerekētia rānei.
- Ātete wera: Mō ngā taiao pāmahana teitei, pērā i runga ake i te 200℃, ka taea te whakaaro ki te whakamahi i tētahi kaihoko whakamaroke silicone, i tētahi kaihoko whakamaroke rānei he hanganga kakara maha.
E ai ki te taiao whakamahinga
- Taiao o roto: he nui ngā whakaritenga tiaki taiao, he pai ake te whakamahi i te kaihoko whakaora epoxy wai-pūtake, te kaihoko whakaora amine aliphatic iti-te-rererangi rānei.
- Taiao o waho: e hiahiatia ana he ātete pai ki te huarere, he pai ake ngā kaihoko whakamaroke amine alicyclic me te ātete pai ki te UV.
- Ngā taiao motuhake: I ngā taiao he nui ngā whakaritenga akuaku pēnei i te kai me te rongoā, me whiriwhiri ngā kaihoko whakamaroke epoxy kore-paitini, iti-paitini rānei pēnei i ngā kaihoko whakamaroke polyamide kua whaimanahia he haumaru kai.
Whakaarohia ngā whakaritenga tukanga
- Te wā mahi: Mō te wā mahi roa, whiriwhiria he kaihoko whakamaroke huna, pērā i te dicyandiamide, me ētahi atu. Mō te wā mahi poto me te wā whakamaroke, whiriwhiria he kaihoko whakamaroke amine aliphatic tere te whakamaroke.
- Te Āhua Whakamaroke: Mō te āhua whakamaroke kore tae, mārama hoki, whiriwhiria ngā kaihoko whakamaroke amine alicyclic, me ētahi atu. Mō ngā tae iti, whiriwhiria ngā kaihoko whakamaroke amine whānui utu iti.
I honoa ki te take utu
- I raro i te kaupapa o te whakatutuki i ngā whakaritenga mahi, whakatairitehia te utu me te horopeta o ngā momo rongoā whakamaroke. He iti te utu o ngā rongoā whakamaroke amine noa, engari he nui ake te utu o ētahi rongoā whakamaroke mahi motuhake pērā i ngā rongoā kei roto he wheori me he silicone.
