Mō ngā whakaritenga ārai mura o te hautai rapa, koinei te tātaritanga e whai ake nei i runga i ētahi ārai mura o nāianei (konumohe hauwai, konutea borate, konumohe hipofosfata, MCA) me ngā taunakitanga hanganga:
I. Tātari i te Whaihua o te Ārai Mura o nāianei
Konumohe Waikawa (ATH)
Ngā Painga:
- He pai mō te taiao, he iti te utu.
- Ka mahi mā te pirau endothermic me te tukunga mamaoa wai, he pai mō ngā pūnaha kore-halogen.
Ngā ngoikoretanga:
- Me nui te uta (30-50 phr) kia whai hua ai, ka pā pea tēnei ki te ngāwari me te mātotoru o te hautai.
Te Whakamahinga:
- He pai mō ngā whakatakotoranga ātete mura taketake.
- E taunakitia ana kia whakakotahitia me ngā rongoā āwhina tahi (hei tauira, te konutea borate).
Konutea Pōrata
Ngā Painga:
- He ārai mura tahi, ka whakarei ake i te whai huatanga o te ATH.
- Ka whakatairanga i te hanganga waro, ka pehi hoki i te paoa.
Ngā ngoikoretanga:
- He iti te whai huatanga ina whakamahia takitahi; me whakakotahi me ētahi atu ārai mura.
Te Whakamahinga:
- E taunakitia ana hei āwhina i te ATH, i te konumohe hypophosphite rānei.
Konumohe Hypophosphite
Ngā Painga:
- He tino whai hua, kāore he halogen, he iti te uta (10-20 phr).
- He pai te pumau o te wera, he pai mō ngā whakaritenga ātete mura.
Ngā ngoikoretanga:
- Te utu teitei ake.
- Me manatoko te hototahitanga ki ngā pūnaha rapa.
Te Whakamahinga:
- He pai mō ngā paerewa ātete mura teitei (hei tauira, UL94 V-0).
- Ka taea te whakamahi takitahi, te whakamahi tahi rānei.
MCA (Melamine Cyanurate)
Ngā Painga:
- He ātete mura kei roto i te hauota, he pehi paowa.
Ngā ngoikoretanga:
- Kāore i te tino marara.
- Tērā pea ka whakararuraru i te pupuhi o te huka.
- Te pāmahana pirau teitei (~300°C), kāore i te ōrite ki te tukatuka rapa pāmahana iti.
Te Whakamahinga:
- Kāore i te tūtohutia hei kaupapa matua; me whakamanahia mā te whakamātautau.
II. Ngā Hanganga me ngā Whakaaro Tukanga i Manakohia
Te Hanganga 1: ATH + Konutea Pōrata (Kōwhiringa Ōhanga)
Te hanganga:
- Konumohe Hauwai (ATH): 30-40 phr
- Konutea Pōrata: 5-10 phr
- Kaiwhakamarara (hei tauira, te kaihoko honohono silane): 1-2 phr (ka whakapai ake i te marara)
Ngā Āhuatanga:
- He iti te utu, he pai mō te taiao.
- He pai mō ngā whakaritenga whānui mō te ātete mura (hei tauira, UL94 HF-1).
- Tērā pea ka paku whakaiti i te pakari o te hautai; me arotau te whakapūkara.
Te Hanganga 2: Konumohe Hypophosphite + Konutea Borate (Kōwhiringa Tino Whai Hua)
Te hanganga:
- Konumohe Hypophosphite: 15-20 phr
- Konutea Pōrata: 5-8 ōrau
- Kaiwhakaahua (hei tauira, parafini wai): 2-3 phr (whakapai ake i te ngāwari o te tukatuka)
Ngā Āhuatanga:
- He pai te ātete ki te mura, he iti te kawenga.
- He pai mō ngā horopaki tono nui (hei tauira, te tahu poutū V-0).
- Me whakamātau te hototahitanga o te konumohe hypophosphate me te rapa.
Te Hanganga 3: ATH + Hypophosphite Konumohe (Kōwhiringa Taurite)
Te hanganga:
- Konumohe Waikawa: 20-30 phr
- Konumohe Hypophosphite: 10-15 phr
- Konutea Pōrata: 3-5 phr
Ngā Āhuatanga:
- Ka whakataurite i te utu me te mahi.
- Ka whakaiti i te whakawhirinaki ki tētahi ārai mura kotahi, ka whakaiti i te pānga ki ngā āhuatanga ā-tinana.
III. Ngā Whakaarohanga Tukanga
Te Mararatanga:
- Me huri ngā mea ārai mura ki te ≤5μm kia kore ai e pā ki te hanganga o te pahuka.
- E taunakihia ana te horapa i mua ki roto i te rapa, i ngā taputapu whakaranu tere-teitei rānei.
Ngā Tikanga Whakaora:
- Whakahaerehia te pāmahana whakapakeke (ko te tikanga 110-130°C mō te rapa) hei ārai i te pirau wawe o ngā mea aukati mura.
Whakamātautau Mahi:
- Ngā whakamātautau matua: Taupū Hāora (LOI), Tahu Poutū (UL94), Kiato, Manawanui.
- Ki te kore e ranea te ātete mura, whakapiki haere i te ōwehenga konumohe hypophosphate, ATH rānei.
IV. Ngā Taunakitanga Tāpiri
Whakamātautau MCA:
- Ki te whakamātautau, whakamahia te 5-10 phr i roto i ngā puranga iti hei tirotiro i te pānga ki te ōritetanga o te huka.
Ngā Tiwhikete Taiao:
- Me whakarite kia tutuki ngā ārai mura kua tīpakohia i ngā whakaritenga RoHS/REACH mō ngā kaweake.
Ngā Ranunga Whakakotahi:
- Whakaarohia te tāpiri i ētahi iti o te nanoclay (2-3 phr) hei whakarei ake i ngā pānga ārai waro.
