I roto i te whanaketanga tonu o te umanga peita, ko te whakapai ake i te mahi paninga te whāinga matua, me ngā tāpiringa ware pi he wāhanga nui. He pānga nui tō rātou auahatanga me te whakamahinga ki te kounga o te paninga. Mai i ngā ware maori o mua ki ngā ware hangai iti-ngota, ā, i nāianei ki ngā ware paura moroiti hangai kua whakarerekētia he ngota teitei, ko te whanaketanga o ngā ware pi e whakaata ana i te ahunga whakamua o te hangarau paninga. E arotahi ana tēnei tuhinga ki te whakamahinga auaha o te ware paura moroiti hangai kua whakarerekētia he ngota teitei ki roto i ngā paninga, me te ruku hohonu ki ōna painga mahi, ngā tikanga whiriwhiri, me ngā horopaki whakamahinga noa. Ko tōna whāinga he whakarato i ngā tohutoro whānui me te mahi mō ngā tohunga ahumahi, hei āwhina i ngā hua paninga kia tutuki ai ngā putanga hou i roto i te ātete ki te rakuraku, te ātete ki te kakahu, te ātete ki te pāmahana, me te ātete ki te huarere, kia whakatairanga ai i te whakaputanga hoa-taiao me te whanaketanga kounga teitei.
① Ngā Wero Matua e Toru o te Ware i roto i ngā Whakamahinga Paninga Utu-Nui:
• Te Wero o te Rahunga i te Pāmahana Teitei: I roto i ngā paninga motuka/taputapu, ka ngohengohe ngā ngota ware pi i ngā pāmahana >150°C, ka piki ake te ngaronga kakahu mā te 50% me te heke o te pakari.
• He Wero mō te Mahi Mata iti: Kāore e taea e ngā ware pi tuku iho te aro atu ki te ātete paheke, te ātete rakuraku, te ātete kakahu, te pā o te ringa, me ētahi atu whakaritenga maha-mahi, ka whakawhāiti i te whānuitanga o te whakamahinga o ngā paninga.
• Te Kaupapa Ārai Whānui a te EU: E kapi ana i ngā momo PFAS neke atu i te 10,000 (tae atu ki ngā fluoropolymers, pērā i ngā mea e whakamahia ana i roto i ngā paninga ātete wai).
2025: Tauira tono me te karanga mō ngā urupare.
2026-2027: E tumanakohia ana kia whakatinanahia katoatia.
② Te Whakapai Ake i te Mahi Whā-Ahu o te Waru Whakarerekētanga Hanga-Ngāo-Tiketike:
• Ātete ki te Paka/Rakuraku: Ka whakanuia ake e te ware pi kua whakarerekētia he nui ngā ngota ira te ātete ki te paka o te paninga, me te tere whakapai ake tae atu ki te 50%, ka roa ake te roa o te oranga o te paninga.
• Mahi Mata: Ka taea te pā ki te mata, te ārai paheke, te ārai wai, te ārai hinu, me te ārai hinu, me ētahi atu āhuatanga maha-mahi, me te whakapainga 30% i roto i te mahi mata hei whakatutuki i ngā hiahia kanorau.
• Ātete ki te Pāmahana/Huarere: Ko te ware pi whakarerekētanga ngota-tiketike he nui ake i te 260°C te ira rewa, ka whakapai ake i te ātete paninga ki te pāmahana/huarere mā te 20%, ka whakarite kia mau tonu te mahi i roto i ngā taiao uaua.
• Nā te ātete whānui ki te pāmahana teitei me te kakahu, he huarahi whai hua tēnei hei whakakapi i ngā ware pi PTFE.
Me pēhea te whiriwhiri i te WAX tika
Ko te ira rewa o te ware pi e whakatau ana i tōna taiao e tika ana me te pumau o te mahi:
| Awhe Rewa | Ngā tono | Ngā Hua Noa |
| <100℃ | Te whakakanapa i te peita rakauPaninga whakamaroke pāmahana iti | Ware CarnaubaWare pī |
| 100–300℃ | Paninga whānui | Ware PE, Ware Fischer Tropsch, PTFE, Ware Polymer |
| >300℃ | Paninga pāmahana-teitei | PTFE, Ware polymer kua whakarerekētia |
Ka pā tika te rahi o te matūriki o te ware pi ki te kanapa, te āhua, me te mahi tiaki o te paninga:
| Rahi Matūriki (D50) | Pānga ki te paninga | Ngā tono |
| <1μm | Kāore he pānga ki te kanapa, he ātaahua te pa: | Paniatanga kanapa teitei, paninga hua hiko |
| 3–7μm | Ka whakarei ake te āhua matte i te ātete ki te rakuraku | Peita tāonga whare, peita kirihou |
| 8–15μm | He mutunga matte nui, he ātete ki te kakahu kua whakarei ake | Peita matte, peita papa |
| >25μm | Waihangahia he pānga kakano onepu | Peita toi, peita pānga motuhake |
Ka whakatauhia e te āhua pōraruraru te hototahitanga me te mahi a ngā pūnaha ware pi me te kapia:
He ware piro teitei (pērā i te ware polyolefin waikawa, te ware polymer whakarerekētia): he pai te hototahi me te marara ki ngā kapia polar (pērā i ngā pūnaha wai-e hangai ana, epoxy, polyurethane), ka whakapai ake i ngā āhuatanga hangarau o te paninga, ka whakarei ake i te piri me te kaha o te mata;
Te ware pi iti te kaha (pērā i te ware pi PE, PTFE): ka heke ki te mata o te paninga hei hanga i tētahi paparanga wai-hauāwhio, he ātete ki te wai, he kore piri, he pā te rongo.
He rerekē ngā momo tāpiri ware pi e tika ana mō ngā tukanga whakaputa rerekē:
| Ngā Puka | Te tukatuka | Ngā Painga | Ngā ngoikoretanga |
| Ware whakamākūkū | Te mira jetWhakamaroke rehu | 100% te ihirangi totoka Kāore he pānga ki te ātete wai | He uaua ki te marara |
| Whakarewa ware pi | Te whakaemulsification | Ngāwari ki te whakamahiRahi matūriki ōrite | Kei roto te emulsifierTērā pea ka whakaiti i te ātete wai |
| Parai ware pi | Te huri mākū | He pai te pumauNgāwari ki te whakamahi | Te whakarewa kei rotoTeitei o te VOC |
Ngā tono noa me te tohutoro mō te ware pi/tāpiritanga:
| Ngā tono | Ngā whakaritenga matua | Ngā momo kua tūtohutia | Inenga |
| Paninga waka | Ātete ki te rakuraku, maeneene ki te pā | Ware PE, Ware Carnauba | 0.5-2% |
| He konganuku tānga, he rauemi koiri | Ātete ki te rakuraku, iti te tauwehenga waku (<0.2) | Ware polymerWare PE/PTFE | 0.5-1.5% |
| Peita papa | Ātete ki te mau, ā, ātete hoki ki te horo o te onepu | PP, Ware polymer | 1-3% |
| Paninga ahumahi | Ātete ki te kakahu, ā, ātete ki te rakuraku | Ware polymerWare PE/PTFE | 0.8-1.5% |
| Paninga paura | Te whakahinuhinu, te ātete ki te rakuraku, me te tango huka | PE, FT, PP, PA, PTFE | Kāore |
| Waituhi | Ātete kakahu, tauwehenga waku iti | E ai ki ō hiahia | Kāore |
He tohunga tā mātou kamupene ki te whakarato i ngā momo whakaritenga mō te ware pi hangai (Polymer).
