Ngā Pūnaha Huka HFO: He Otinga Hoahoa Taiao mō ngā Huka Polyurethane

Ko ngā Hydrofluoroolefins (HFO) he whakatupuranga hou o ngā matū pupuhi e pai ana ki te taiao e whakamahia ana i roto i ngā pahuka polyurethane. I te mea kua piki haere te aro o te ao ki te whakaiti i te pānga ki te taiao, kua riro ko ngā HFO hei whiringa pai mō ngā momo tono, hei whakakapi i ngā hydrofluorocarbons tawhito (HFC) nā te mea he pai te āhua ki te taiao.

He aha te HFO?

Ko ngā HFO he momo matū e whakamahia ana hei whakamatao, hei pupuhi, hei whakarewa, hei whakarewa. I roto i ngā pūnaha pahuka polyurethane, ka mahi ngā HFO hei pupuhi e āwhina ana ki te hanga i te hanganga pūtau o ngā pahuka, e whai wāhi ana ki ō rātou āhuatanga whakamarumaru, pakari, me te pumau.

Kua rongonui haere ngā HFO i te mea kua whakakorea haeretia ngā HFC i runga anō i ngā ture o te ao e aro ana ki te whakaiti i ngā matū he nui te kaha ki te whakamahana ā-ao (GWP). Ahakoa i whakamahia whānuitia ngā HFC, pērā i te HFC-245fa, i roto i ngā pūnaha pahuka, he nui te GWP o rātou, ā, ka whai wāhi atu ki te whakaiti i te ozone. He rerekē, kāore he kaha ki te whakaiti i te ozone (ODP) o ngā HFO, ā, he iti ake ngā uara GWP, ā, he pai ake te whakamahi hei huarahi tauwhiro.

Ngā Painga o ngā Pūnaha Whakahuka HFO

1. Pānga Iti ki te TaiaoKo te painga nui o ngā HFO ko te iti o te pānga ki te taiao. Kāore he ODP o ngā HFO, ā, he iti rawa te GWP, e whai wāhi ana tēnei ki te whakaiti i ngā tukunga hau kati kōtuhi.
2. Te Whai Hua o te PūngaoHe tino pai ngā āhuatanga whakamahana o ngā pahuka HFO, e whakarei ake ana i te whai huatanga o te pūngao o ngā tono pēnei i ngā pouaka whakamātao, ngā pouaka tio, ngā whakamahana pahuka rehu, me ngā rauemi hanga.
3. Haumaru me te WhānuitangaKāore ngā HFO e mura, kāore e paitini, ā, he maha ngā whakamahinga puta noa i ngā pūnaha pahuka maha, tae atu ki ngā pahuka pakari me ngā pahuka ngāwari. He tino pai mō ngā pūnaha e whakamahi ana i te wai hei pūnga pupuhi tahi, ā, ka whakaiti ake i te whakawhirinaki ki ngā pūnga matū tuku iho.
4. Ngā Āhuatanga Pahuka Whakapai AkeKa whai wāhi ngā HFO ki te hanganga pūtau pai, ōrite i roto i ngā pahuka polyurethane, e āwhina ana ki te pupuri i te kaha ā-pūkaha, te pumau o ngā āhuatanga, me te mahi pahuka whānui. Ka whakaitihia hoki e rātou te pakarukaru o te pahuka, ka whakapai ake i te pakari o te mata, ā, ka whakarei ake i te piri i waenga i ngā papa.

Te Anamata o ngā HFO i roto i ngā Pahuka Polyurethane

I te mea kei te piki haere tonu te hiahia o te ao mō ngā rauemi e pai ana ki te taiao me te penapena pūngao, e matapaetia ana ka nui ake te rongonui o ngā pūnaha pahuka HFO i roto i te umanga pahuka polyurethane. Ko te whakawhiti mai i ngā HFC ki ngā HFO ehara i te mea ka tutuki noa i ngā ture taiao, engari ka whakarite hoki ka taea tonu e ngā kaihanga te whakaputa pahuka mahi-teitei me te whakaiti i te pānga ki te taiao.

I tō mātou kamupene, e whakapau kaha ana mātou ki te whakatairanga i te hangarau whakakorikori polyurethane hei tautoko i ngā pūnaha pahuka HFO.Whakakōkī MXC-70, i hangaia mō te whakamahi me ngā pūnaha HFO, ka whakapai ake i te whakamaroke o te mata, ka whakatairanga i te pikinga maeneene, ā, ka whakarei ake i te piri o te papa. He tino pai hoki mō ngā pūnaha e whakamahi ana i te wai hei kaihopu pupuhi tahi, e whakarato ana i te ngāwari me te iti o ngā tukunga i roto i ngā tono pahuka ngāwari me te pakari.
