He aha te Hiahia mōHe aha ngā momo whakakapi mō te PTFE (PFAS)?

I tēnei ao tere whanake o ngā rauemi tauwhiro, kei te pāngia ngā ahumahi e te pēhanga nui haere ki te tango i ngā otinga hoa taiao. Kāore he rerekētanga o ngā kirihou hangarau, e mōhiotia ana mō tō rātou pakari me te maha o ngā whakamahinga. Mō ngā tau maha, ko te PTFE (Polytetrafluoroethylene) te rauemi matua mō ngā kirihou hangarau, he mea nui mō tō rātou ātete matū, te iti o te waku, me te pumau wera teitei.

Heoi, nō te whānau PFAS (Per- me Polyfluoroalkyl Substances) te PTFE, ā, kua ara ake ngā āwangawanga nui mō te taiao nā tōna pumau me tōna ātete ki te pirau. E kiia ana ko ngā "matū pumau tonu", ka taea e te PFAS te kohikohi i roto i ngā rauropi me te whakararu i te hauora o te tangata, tae atu ki ngā take e pā ana ki te pūnaha ārai mate me te pūnaha endocrine, te mahi ate, me ngā mate kino atu pērā i te mate pukupuku.

Hei whakautu i ēnei wero, he maha ngā whenua e whakakaha ana i ngā ture e pā ana ki ngā matū PFAS. Hei tauira:

Kua tautuhia e te ture REACH a te Kotahitanga o Ūropi te PFAS hei "matū e tino āwangawanga ana," ā, nā reira i tino herea ai tōna whakamahinga.

Kua tīmata te Tari Tiaki Taiao o Amerika (EPA) i ngā mahere aroturuki me te whakakore i ngā matū PFAS.

Nā, me pēhea e taea ai e ngā kirihou hangarau te pupuri i tō rātou mahi teitei me te whakaiti i te pānga ki te taiao? Ko ngā otinga Kore-PFAS me te Kore-PTFE te whakautu tino pai, e tuku ana i ngā painga mahi teitei me te kore he mōrearea ki te taiao me te hauora.

He aha te mea hei whakakapi i te PTFE? Te Mahi-Teitei,Ngā Tāpiri Kore-PFAS mō ngā Kirihou Hangarau

Te Whakauru i ngā Tāpiri Ātete-Kakahu Kore-Hūrou SILIKE me ngā Huarahi Whakakapi PTFE

Ngā Painga Matua o te Tāpiri Whakakapinga PTFE SILIKE LYSI-701 mō ngā Kirihou Hangarau:

1. Te Hanganga Kore-Pūhau: He hanganga kore-PFAS e hangai ana ki ngā paerewa taiao pakari o te ao.

2. Te Ātete Paku Whakarei Ake: Ahakoa he iti noa te nui o tēnei tāpiri ka taea te whakapai ake i te roa me te roa o te ora o ngā kirihou hangarau ina whakaritea ki te PTFE.

3. Whakahinuhinu Pai Rawa: Ka whakaitihia te waku me te whakarei ake i te pai o te tukatuka, ka pai ake te mahi.

4. Whānui te Whakamahinga: He pai mō ngā rauemi kanorau pēnei i te PA6, PA66, PC, ABS, POM, PBT, PPS, me te maha atu o ngā kirihou hangarau.

E whakamanahia ana e ngā whakamātautau taiwhanga: Ko te 3 wt% LYSI-701 i roto i te POM e whakaatu ana i te ātete kakahu pai ake me te tauwehenga waku iti iho (COF) ki te whakaritea ki te 10 wt% PTFE i raro i ngā tikanga whakamātautau ōrite.

He Aratohu Hou mō te Karo i te PTFE me te PFAS (Forever Chemicals) i roto i ngā Hua Hangarau Kirihou

Ki ngā kairangahau e mahi ana i te ao o ngā kirihou hangarau, kei te rapu huarahi koutou ki te whakatau i ngā wero e pā ana ki te aro turuki haere o ngā ture mō te PFAS i roto i ngā kirihou hangarau? Kei te rapu koutou i ngā tāpiringa mahi-teitei, i ngā kaihoko ārai-paowa, i ngā whakarerekētanga rānei o ngā kirihou hangarau, i tētahi whakakapinga rānei mō te PTFE e whakatairanga ana i te hauora o te taiao?

Ko te taenga mai o ngā rauemi hou kāore he PFAS ka huaki i te ao o ngā mea ka taea. Kāore ēnei huarahi kē e taea te whakataurite i te mahi a te PTFE engari ka taea hoki te whakaiti i tōna tapuwae taiao.

Mā te pupuri i tētahi tūnga e aro nui ana ki te haumaru me te taiao, ka ārahi mātou i ō mātou kiritaki i roto i ngā uauatanga o tēnei mākete e whanake haere ana. Kua tīmata a SILIKE i ētahi otinga kore-PFAS kua whakaritea mō ngā tono kirihou hangarau. Ka tū mātou hei hoa tautoko i a koe i roto i te rapu huarahi tauwhiro hei whakakapi i te PTFE me te whakarērea i ngā matū PFAS kino pea.
