Ngā Auahatanga Whanaketanga o ngā HFO Hoa Taiao me ngā Otinga Whakakōkī Matatau

I te tere haere o te whai i ngā whāinga āhuarangi o te ao, kei te pāngia te umanga polyurethane e ngā huringa nui. Ko te whakawhiti mai i ngā pūwero pupuhi tuku iho ki te pūwero pupuhi taiao ngā HFO e pai ana ki te taiao(Ngā Waiwhakapūngao Hauota)kua waiho hei whakahoutanga hangarau nui mō ngā rauemi whakamahana, te pahuka polyurethane rehu (SPF), te pahuka pakari, te whakamahana taputapu kāinga, me ngā tono motuka. I te wa ano, kei te tipu haere tonu te tono mōngā whakakorikori HFO mahi-teitei kei te akiaki i ngā kaihanga ki te whakamahi i ngā otinga whakakorikori ma ake, whai hua ake, me te pumau ake.

1. He aha ngā HFO e huri nei hei Paerewa Ao

1.1 Mai i te CFC ki te HFO: Te Whakatipuranga Tuawhā o ngā Ākena Pupuhi

Ko te whanaketanga o ngā pūnga pupuhi e whai ana i tētahi ara ture me te ara taiao mārama:

2. Ngā Painga Matua o ngā HFO Hoa Taiao

✔ Tino iti te GWP (<1) – 99.9% te whakahekenga ki ngā HFC

Ngā HFO pēnei iHFO-1234yf, HFO-1233zd, meHFO-1234zeka tere te pirau i roto i te hau, ā, ko te roanga o te ora hengā rā ki ngā wiki, ka tino whakaiti i te pānga ki te āhuarangi.

✔ Kore ODP – Kāore he kino ki te paparanga ozone

✔ He pai te whakamahana me te whai hua o te pūngao

He pai ake te kawe wera o te pahuka HFO, ā, he pumau ake hoki ōna āhuatanga, he mea tino pai mō:

• Ngā taputapu whakamatao
• Ngā panera whakamahana whare me ngā panera hanawiti
• Pahuka polyurethane rehu (SPF)

✔ He rere teitei ake, he hanganga pūtau pai ake

Ko ngā āhuatanga ā-tinana o te HFO e hiahiatia anangā whakakorikori me te tauhohenga kua arotauhia, inā koa mō te whakataurite i te pikinga, te rere, me te whakamaroke o te pahuka.

3. Te Hurihanga a ngā HFO i te Ahumahi Polyurethane

3.1 Te Whakamahinga Tere puta noa i ngā Rāngai Matua

Nā tēnei nekehanga tere ka puta he hiahia nui mōNgā whakakorikori polyurethane kua arotauhia e te HFO.

4. Ngā Wero Whakakorikori i roto i ngā Pūnaha HFO

Ka tino whakarerekē te hurihanga matū o ngā tauhohenga PU i te whakawhiti ki ngā matū pupuhi HFO:

Ko ngā hanganga HFO te tikanga kei roto:

• Te iti o te tauhohenga tuatahi
• Ngā rerekētanga wairewa teitei ake
• Te whanonga hou o te pahuka
• Ngā whakaritenga pakari ake mō te whakamaroke mata
• Te matotoru teitei ake i roto i ngā ranunga-mua

Nō reira, me whakamahi ngā kaihanga pahukangā whakakorikori HFO motuhakee whakarato ana:

✔ He kaha ake te taurite o mua

Hei whakakapi mō te whakaiti i te tīmatanga o te tauhohenga HFO.

✔ He pai ake te rere o te wai

He mea tino nui mō ngā panera PIR, SPF, me ngā raina whakaputa tonu.

✔ Tere te whakamaroke o te mata

Hei ārai i te mimiti me te hinga o te pūtau.

✔ He iti te kakara, he iti hoki ngā tukunga

Te whakatutuki i ngā ture taiao o te ao.

5. Ngā Otinga Whakakōkī Matatau mō ngā Pūnaha HFO

Hei kaihanga whakakorikori polyurethane ngaio, ka whakaratohia e mātou he kohinga katoa i hangaia mōngā HFO e pai ana ki te taiao.

Ngā Whakakōkī HFO-Arotau kua Manakohia

• MXC-B20：He whakaroa pai rawa atu i mua, he kaha te whakaora i muri, he pai mō te HFO SPF
• MXC-R40：Ka whakapai ake i te whakaora o te mata, he mea tino pai mō ngā pūnaha pupuhi-tahi wai/HFO

Ka aro atu ēnei whakakorikori ki ngā wero hanga HFO noa, pēnei i:

• Tīmatanga puhoi
• Te pikinga kore taurite
• Te kore pumau o te pūtau
• Te pakarukaru i muri i te whakaora

6. Te Tirohanga ki te Auahatanga o te Mākete: Ka Mana te Whakaurunga HFO + Catalyst i te Tekau Tau e Whai Ake Nei

6.1 Kei te piki haere te tono HFO o te ao i te >10% ia tau

E ārahihia ana e te hanganga penapena-pūngao, te hiko o ngā motuka, me te whakawhānui i te mekameka matao.

6.2 Me whanake ngātahi ngā pūnaha whakakorikori

Kāore e taea e ngā HFO te whakatutuki i te mahi tino pai me te kore he whakakorikori i hangaia mō ō rātou matū.

6.3 Ka whakamahia whānuitia ngā whakakorikori iti-kakara, iti-VOC

Kei te tere ake tēnei ia e ngā ture taiao (EPA, EU F-Gas, ngā whāinga waro-rua a Haina).

6.4 Ka tere te horapa o ngā panera whakamahana PIR e hangai ana ki te HFO

Ina koa i roto i:

• Ngā whare kua oti te hanga
• Rokiroki matao
• Hanganga ā-pūrua
• tuanui ahumahi

7. Whakamutunga: Mā te HFO me te Catalyst Innovation e tautuhi te heke mai o te Polyurethane

Te nekehanga ā-ao kingā HFO e pai ana ki te taiaohe whai wāhitanga hītori tēnei mō te umanga polyurethane. I te mea kua whakakorea ngā HFC me te whakakaha haere i ngā ture, me whakamahi e ngā kaihanga ngā taputapu mahi-teiteiNgā whakakorikori HFOhei whakatutuki i te taurite tauhohenga, te whai huatanga, me te pumau e hiahiatia ana.

Ā mātou otinga whakakorikori—tae atu kiMXC-B20,MXC-TMA, MXC-10, me ētahi atu—kua hangaia hei āwhina i ngā kaihanga polyurethane kia neke maeneene ki te wā HFO, e tuku ana i:

• Te pai ake o te whakamahana
• Te whakaputanga ma, matomato hoki
• Tukatuka pumau i roto i te pahuka pakari me te pahuka rehu
• Te tutuki i ngā paerewa taiao o te ao

Mā te whakakotahi i ngā matatauNgā kaihoko pupuhi HFOme te arotaungā whakakorikori polyurethane, ka tutuki i te umanga te mahi tino pai me te whakaiti waro whai tikanga—hei tautoko i tētahi heke mai e mau tonu ana, e whai hua ana hoki ki te pūngao.
