Te hurihanga hangarau o te kaihoko pahuka HFO me te ia o te tiaki taiao
I raro i te mana o ngā ture taiao o te ao e kaha haere ana, ko ngā hydrofluoroolefins (HFO), te whakatupuranga tuawhā o ngā kaihoko pahuka ā-tinana, kei te tere whakakapi i ngā kaihoko pahuka HCFC me HFC tuku iho. Nā te iti rawa o te kaha whakamahana ā-ao (GWP<1) me te kore āhuatanga whakaheke ozone (ODP=0), kua noho te pūnaha pahuka HFO hei ara hangarau matua mō te umanga polyurethane kia tutuki ai te whanaketanga tauwhiro. E ai ki ngā rangahau mākete hou, i te tau 2026, e matapaetia ana ka piki te wahanga mākete o te HFO i roto i ngā kaihoko pahuka polyurethane ki te 58%, me te tere tipu ā-tau o te 12.3%.
Ngā painga hangarau matua o te pūnaha pahuka HFO
1. Te whanaketanga o te mahi taiao
- Uara GWP <10: neke atu i te 99% te iti iho i te HFC-245fa (GWP=1030)
- Kore ODP: kāore e kino te paparanga ozone, ā, e tutuki ana i ngā whakaritenga o te Montreal Protocol
- He iti ngā tukunga VOC: e tutuki ana i ngā paerewa tiwhikete whare matomato pēnei i te LEED me te BREEAM
2. He mahi whakamātao tino pai
He pai ake te kawe wera o te hinu whakapūkara HFO (0.013-0.015 W/m·K) i ērā o ngā hinu whakapūkara tuku iho, ā, ka taea e tēnei te whakaiti i te kawe wera whānui o te pahuka polyurethane mā te 15-20%, ka puta he pānga nui ki te penapena pūngao mō ngā pouaka whakamātao, te whakamarumaru whare me ētahi atu mara.
3. Ngā wero me ngā otinga mō te urutau tukanga
Nā ōna āhuatanga ā-tinana motuhake (pēnei i te ira kohua, te wera o te mimiti, me ētahi atu), ka whakatakotohia e ngā kaihopu pupuhi HFO ngā whakaritenga hou mō ngā hanganga me ngā tukanga polyurethane:
- Me whakahaere tika ake te tere o te tauhohenga
- Whakapai ake i te taurite i waenga i te pahuka me te whakapūpū
- Whakapai ake i te ōritetanga o te hanganga pūtau
- Whakapai ake i te mahi here o te papa
Koinei te uara o tā mātou whakakorikori MXC-70 i whakawhanakehia mō ngā pūnaha HFO.
Whakakōkī MXC-70te hoa tino pai mō te pūnaha HFO
Ngā āhuatanga matua o te hua
He whakakorikori amine iti-kakara te MXC-70 i hangaia mō te whakaoti rapanga matua e toru o te pūnaha pahuka HFO:
1. Whakahaere i te pihi tauhohenga maeneene
- Whakahaere tika i te taurite o te mimiti HFO me te tere whakaora polymer
- Ārai i te hinganga, te ngatata rānei o te pahuka
- Te paerewa rerekētanga o te pihi e piki haere ana <5% (whakamātautau ASTM D7487)
2. He mahi whakaora mata tino pai
- Whakaitihia te piri o te mata, ā, whakapai ake i te āhua o te pahuka
- Whakapotohia te wā tangohanga mā te 15-25%
- He pai mō te rehu poutū me te rehu mata o runga
3. Te piri o te paparanga kua whakarei ake
- Te whakanui ake i te kaha o te piri ki ngā momo papa pēnei i te konganuku, te kirihou, te rakau, me ētahi atu mā te 30-50%
- He tino pai mō te raina whakaputa tonu o ngā panera hanawiti
