Ko te nairona (Polyamide, PA) he kirihou hangarau mahi-teitei e whakamahia whānuitia ana i roto i ngā hikohiko, ngā motuka, ngā kakahu, me ētahi atu mara. Nā tōna ngāwari ki te mura, he mea nui te whakarerekētanga ātete mura o te nairona. Kei raro nei he hoahoa taipitopito me te whakamārama o ngā whakatakotoranga ātete mura o te nairona, e kapi ana i ngā otinga ātete mura halogen me te kore halogen.
1. Ngā Mātāpono o te Hoahoa Hanganga Ārai Mumura o te Nairon
Me piri te hoahoa o ngā hanganga aukati mura nairona ki ngā mātāpono e whai ake nei:
- Te Ātete ki te Mura Nui: Tutuki i ngā paerewa UL 94 V-0, V-2 rānei.
- Te Mahi TukatukaKaua ngā ārai mura e pā nui ki ngā āhuatanga tukatuka o te nairona (hei tauira, te rere, te pumau wera).
- Ngā Āhuatanga MīhiniMā te tāpiri i ngā ārai mura ka whakaiti i te pānga ki te kaha, te pakari, me te ātete ki te kakahu o te nairona.
- Te Aroha ki te TaiaoWhakatairangahia ngā ārai mura kore-halogen kia tutuki ai ngā ture taiao.
2. Te Hanganga Nairona Ārai Mumura Halogenated
Ka whakakorea e ngā matū aukati mura kua whakakōroria (hei tauira, ngā matū brominated) ngā tauhohenga mekameka mura mā te tuku i ngā irahiko halogen, ka tuku i te tino whai huatanga aukati mura.
Te Hanganga o te Hanganga:
- Kapia nairona (PA6, PA66 rānei): 100 phr
- Ārai mura brominated: 10–20 phr (hei tauira, decabromodiphenyl ethane, brominated polystyrene)
- Antimony trioxide (synergist): 3–5 phr
- Hinu whakahinuhinu: 1–2 phr (hei tauira, te konupūmā stearate)
- Ārai mate pāwera: 0.5–1 phr (hei tauira, 1010, 168 rānei)
Ngā Hipanga Tukatuka:
- Whakaranua te kapia nairona, te aukati mura, te synergist, te hinu whakahinuhinu, me te antioxidant kia ōrite.
- Whakarewahia te ranunga mā te whakamahi i te mīhini whakaputa tīwiri-rua ka whakapūpū i te kirikiri.
- Whakahaerehia te pāmahana whakaputa i te 240–280°C (whakarerekētia i runga i te momo nairona).
Ngā Āhuatanga:
- Ngā PaingaHe pai te ātete mura, he iti te nui o te tāpiri, he iti te utu.
- Ngā ngoikoretangaTe tukunga pea o ngā hau paitini i te wā e tahuna ana, ngā āwangawanga taiao.
3. Hanganga Nairona Ārai-Mumura Kore-Halogen
Ka mahi ngā aukati mura kore-halogen (hei tauira, ngā waikura kei roto i te phosphorus, te hauota, ngā waikura kore-waro rānei) mā roto i ngā tauhohenga endothermic, te hanganga paparanga tiaki rānei, e tuku ana i te mahi taiao pai ake.
Te Hanganga o te Hanganga:
- Kapia nairona (PA6, PA66 rānei): 100 phr
- Ārai mura i ahu mai i te phosphate: 10–15 phr (hei tauira, te ammonium polyphosphate APP, te phosphate whero rānei)
- Ārai mura i te hauota: 5–10 phr (hei tauira, melamine cyanurate MCA)
- Waikawa kore-waro: 20–30 phr (hei tauira, waikawa konupūmā, waikawa konumohe rānei)
- Hinu whakahinuhinu: 1–2 phr (hei tauira, te konutea stearate)
- Ārai mate pāwera: 0.5–1 phr (hei tauira, 1010, 168 rānei)
Ngā Hipanga Tukatuka:
- Whakaranua te kapia nairona, te aukati mura, te hinu whakahinuhinu, me te antioxidant kia ōrite.
- Whakarewahia te ranunga mā te whakamahi i te mīhini whakaputa tīwiri-rua ka whakapūpū i te kirikiri.
- Whakahaerehia te pāmahana whakaputa i te 240–280°C (whakarerekētia i runga i te momo nairona).
Ngā Āhuatanga:
- Ngā PaingaHe pai mō te taiao, kāore he tukunga hau paitini, e tutuki ana i ngā ture.
- Ngā ngoikoretangaHe iti ake te pai o te aukati mura, he nui ake ngā tāpiringa, ka pā pea ki ngā āhuatanga miihini.
4. Ngā Whakaaro Matua i roto i te Hoahoa Hanganga
(1) Kōwhiringa Ārai Mura
- Ngā aukati mura halogenatedHe tino whai hua engari he mōrearea ki te taiao me te hauora.
- Ngā aukati mura kore-halogenHe pai mō te taiao engari me nui ake ngā rahinga e hiahiatia ana, ā, ka pā pea ki te mahi a ngā rauemi.
(2) Te Whakamahinga o ngā Kaitautoko
- Te toru o te waikura antimoniKa mahi tahi me ngā aukati mura halogenated hei whakarei ake i te aukati mura.
- Te mahi tahi o te whākawa-hauotaI roto i ngā pūnaha kore-halogen, ka taea e ngā aukati mura e hangai ana ki te phosphorus me te hauota te mahi tahi hei whakapai ake i te whai huatanga.
(3) Te Mararatanga me te Tukatuka Āheitanga
- Ngā mea whakamararaKia rite te marara o ngā ārai mura kia kore ai e nui ngā kukū i te rohe.
- Ngā hinu whakahinuhinuWhakapai ake i te rere o te tukatuka me te whakaiti i te pakaru o ngā taputapu.
(4) Ngā Ārai Matewai
Ārai i te pirau o ngā rauemi i te wā e tukatukahia ana, ā, whakarei ake i te pumau o te hua.
5. Ngā Whakamahinga Noa
- Ngā HikohikoNgā wāhanga ātete-mura pērā i ngā hononga, ngā pana, me ngā putanga hiko.
- AunoaNgā mea ātete-mura pērā i ngā taupoki miihini, ngā taura waea, me ngā wāhanga o roto.
- Ngā kakahuNgā muka me ngā papanga ātete-mura.
6. Ngā Taunakitanga mō te Arotautanga o te Hanganga
(1) Te Whakapai Ake i te Whai Hua o te Ārai i te Ahi
- Ranunga ātete muraNgā mahi tahi a te halogen-antimony, te phosphorus-hauota rānei hei whakapai ake i te mahi.
- Ngā ārai mura nanoHei tauira, te nano konupora hauwai, te nano uku rānei, hei whakarei ake i te whai huatanga me te whakaiti i ngā rahinga tāpiri.
(2) Te Whakapai Ake i ngā Āhuatanga Mīhini
- Ngā KaiwhakapakariHei tauira, POE, EPDM rānei, hei whakapakari i te pakari o te rauemi me te ātete ki te pānga.
- Ngā whakakī whakapakariHei tauira, te muka karāhe, hei whakapai ake i te kaha me te pūmau.
(3) Te Whakaiti i te Utu
- Whakapai ake i ngā ōwehenga ārai muraWhakaitihia te whakamahinga me te whakatutuki i ngā whakaritenga ātete mura.
- Kōwhiria ngā rauemi utu-paiHei tauira, ngā ārai mura mō te kāinga, ngā ārai mura whakaranu rānei.
7. Ngā Whakaritenga Taiao me ngā Whakaritenga Ture
- Ngā aukati mura halogenatedKua herea e RoHS, REACH, me ētahi atu, me tūpato te whakamahinga.
- Ngā aukati mura kore-halogenE tutuki ana i ngā ture, e tohu ana i ngā au o te heke mai.
Me whai whakaaro te hoahoa o ngā whakatakotoranga aukati mura nairona ki ngā āhuatanga tono motuhake me ngā whakaritenga ture i te wā e whiriwhiri ana i ngā aukati mura halogenated, kore-halogen rānei. He nui te whai huatanga o ngā aukati mura halogenated engari he tūponotanga taiao, ko ngā momo kore-halogen he hoa taiao engari me nui ake ngā tāpiringa. Mā te arotau i ngā whakatakotoranga me ngā tukanga, ka taea te whakawhanake i ngā rauemi nairona aukati mura whai hua, pai ki te taiao, me te utu iti hei whakatutuki i ngā hiahia o ngā hikohiko, ngā motuka, ngā kakahu, me ētahi atu ahumahi.
