Kei te neke haere te umanga polyurethane ki ngā mahi tauwhiro ake, ā, ko te whakamahinga o ngā pūwero pupuhi hydrofluoroolefin (HFO) kei mua i tēnei panonitanga. He hangarau matatau te pūnaha HFO e whakamahi ana i ngā pūwero pupuhi HFO hei hanga pahuka polyurethane me te mahi pai ake me ngā painga taiao. I te mea kei te whakakorehia ngā pūwero pupuhi tuku iho me te kaha whakamahana ao (GWP) nui nā ngā ture taiao, ka tukuna e ngā pūnaha HFO he huarahi kē atu matomato me tō rātou GWP tino iti.
He aha te HFO?
Ko ngā Hydrofluoroolefins (HFO) he momo matū e mahi ana hei pūwero pupuhi o te whakatupuranga tuawhā i roto i te hanga pahuka polyurethane. Kua hangaia motuhaketia hei whakakapi i ngā whakatupuranga o mua o ngā pūwero pupuhi pērā i ngā hydrochlorofluorocarbons (HCFC) me ngā hydrofluorocarbons (HFC), e whai wāhi nui ana ki te whakahekenga ozone me te mahana o te ao. He rerekē, he iti noa te pānga o ngā pūwero pupuhi HFO ki te mahana o te ao, me te pupuri tonu i te whakamarumaru pai me ngā āhuatanga hanganga e hiahiatia ana i roto i ngā tono pahuka.
Ngā Painga o ngā Ākena Pupuhi HFO i roto i ngā Pahuka Polyurethane
- GWP Tino-ItiHe tino iti te GWP o ngā pūwero HFO, ā, ka tino whakaiti i te tapuwae taiao o ngā pahuka polyurethane. He huarahi tauwhiro anō hoki ēnei mō ngā ahumahi e hiahia ana ki te whakaiti i ā rātou tukunga waro.
- Te Whai Hua o te PūngaoKo ngā pahuka polyurethane i hangaia me ngā matū pupuhi HFO he tino pai ngā āhuatanga whakamahana, e whai wāhi ana ki te penapena pūngao i roto i ngā momo tono, tae atu ki te hanga, te pouaka whakamātao, me ngā rāngai motuka.
- Te Whakatutukitanga o ngā TureI te whakakorenga o ngā matū GWP-tiketike i raro i ngā whakaaetanga ā-ao pērā i te Montreal Protocol me te Kigali Amendment, mā te whakamahinga o ngā matū pupuhi HFO ka tutuki ngā ture taiao me te pupuri tonu i ngā paerewa mahi.
- Ngā Taupānga MahaKa taea te whakamahi i ngā pūnaha HFO i roto i te whānuitanga o ngā tono pahuka, tae atu ki te pahuka polyurethane rehu (SPF), ngā panera pakari, ngā taputapu, me ngā pahuka ngāwari. Nā te maha o ngā whakamahinga o ngā kai pupuhi HFO, he pai mō ngā whakamahinga ahumahi maha.
Ngā Whakakōkī Polyurethane mō ngā Pūnaha HFO
Ko te hanga pahuka polyurethane mā te whakamahi i ngā matū pupuhi HFO me whai i ngā whakakorikori motuhake hei whakarite i te tauhohenga tika me te mahi pahuka. I Mingxu Chem, ka hangaia e mātou he whakakorikori polyurethane kounga teitei, tae atu kiMXC-B20 meMXC-70, e tino hototahi ana ki ngā pūnaha HFO. Kua hangaia ēnei whakakorikori hei whakarei ake i te tukatuka pahuka, hei whakapai ake i ngā wā whakamaroke, me te arotau i te hanganga pahuka mō ngā momo tono.
Whakamutunga
He taahiraa nui te whakawhiti ki ngā pūnaha HFO ki te whakaiti i te pānga taiao o ngā pahuka polyurethane. Mā te whakamahi i ngā kaihopu pupuhi HFO me ngā whakakorikori hototahi pērā i te MXC-B20 me te MXC-70, ka taea e ngā ahumahi te whakatutuki i te tutuki i ngā ture me te mahi pahuka pai ake, me te whai wāhi atu ki ngā mahi pumau o te ao.
