Kua noho ko ngā kapu polyurethane (PU) hei paerewa koura mō ngā hu o ēnei rā, mai i ngā pūtu mahi pakari ki ngā hu oma mahi teitei. Kei te ngākau o tēnei auahatanga he tauhohenga matū tika – me ngā whakakorikori e taea ai.
He aha ngā kapu PU i pai ake ai i ngā rauemi tuku iho
E toru ngā painga nui o ngā kapu waewae PU e whakamārama ana i tō rātou mana nui i roto i ngā hu:
1. Te Whakamarie i Hangaia
Mā te hanganga pūtau ahurei o te PU ka ngāwari te hu, he rite ki te hiako, me te pupuri tonu i te āhua. E whakaatu ana ngā whakamātautau motuhake ka mau tonu ngā āhuatanga o ngā kapu PU i roto i ngā huringa neke atu i te 100,000 – he rite ki te hikoi mai i New York ki Los Angeles e rima ngā wā.
2. Te mimiti ru tino pai
Ka mimiti te hanganga pahuka pūtau-kati i te 92% o te kaha pānga, ka whakaiti nui i te ahotea ki ngā hononga. Nā tēnei ka pai te PU mō:
- Ngā hu haumaru (te whakaiti i te ngenge i te wāhi mahi mā te 27%)
- Ngā hu hākinakina (e whakapai ake ana i te hokinga mai o te pūngao mā te 18%)
- Ngā hu hauora (hei tiaki i ngā waewae tairongo)
3. Te Pūmautanga Kore e Taea te Whakaōrite
E toru ngā wā e roa ake ai te mau o ngā kapu PU i ngā kapu rapa noa i roto i ngā whakamātautau pakū, ā, e mau tonu ana te mata maeneene e whakaiti ana i te waku mā te 40% ki te whakaritea ki ngā momo EVA.
MXS-6 Whakakōkī:Te Hangarau Tika mō ngā Tapuwae Tino Pai
Ko tā mātou whakakorikori MXS-6 (CAS 83016-70-0) – he rite ki te paerewa ahumahi DC193 – e tuku ana i te ōritetanga kore e taea te whakataurite i roto i te hanga kapu PU:
- Mana Tauhohenga Tino Pai:Ka mau tonu te ōritetanga o te kirīmi i roto i te ±1.5%, ki te whakataurite ki te paerewa ahumahi o te ±5%
- Hanganga Pūtau Tino Pai:Ka waihanga i te 98% pahuka pūtau-katia mō te roa o te mau
- Tukunga Māmā o te Momo:Ka whakakore i ngā raruraru piri e pāngia ana e te 15% o ngā mahi tuku iho
Te Mahi o te Ao Tūturu
I tutuki i tētahi kaihanga pūtu mahi matua o Ūropi ngā hua whakamiharo me te MXS-6:
- I piki ake te hanga mā te 1,200 takirua i ia rā nā te tere o te tangohanga 18%
- Kāore he wehenga o te kapu ahakoa i ngā pāmahana tino kino (-30°C ki te 120°C)
- Kua whakaitihia te para o ngā rauemi mata mā te 35%
Ngā Painga Hangarau
MXS-6e mahi ana mā roto i ngā tikanga matua e rua:
1. Ka tino whakatauritea e ōna matū horoi silicone ngā atanga polyol/isocyanate, ka whakaiti i te taumahatanga mata mā te 28 dynes/cm
2. Mā te tauhohenga tino whakahaere ka whakaroahia te whakakī i te pokepokea ai mā te 12-15 hēkona, ā, ka pumau tonu i ngā pāmahana whakamaroke pai (65-75°C).
Te Hanganga Ātaahua ki te Taiao
E tutuki ana i a MXS-6 ngā paerewa taiao pakari:
- Kore tukunga VOC (kua whakamanahia e ISO 16000-6)
- E tutuki katoa ana i ngā whakaritenga REACH
- Ka whakaiti i te whakapaunga pūngao mā te tere ake o te wā whakaora
Tō Hoa Mahi i roto i te Auahatanga Hu
Ahakoa he hu haumaru, he hu hākinakina, he hu āhua rānei āu e hanga ana, ka taea e tā mātou tīma hangarau te āwhina i a koe ki te whakapai ake i ō hanganga PU. Whakapā mai ki a mātou i tēnei rā ki:
- Tonoa he tauira kore utu o MXS-6
- Tikina ngā taunakitanga kiato ritenga
- Whakauru atu ki ngā tuhinga tutuki katoa
