Nā ʻōnaehana hoʻohua HFO: He hopena pili kaiapuni no nā hua Polyurethane

Hōʻike nā Hydrofluoroolefins (HFOs) i kahi hanauna hou o nā mea puhi aloha i ke kaiapuni i hoʻohana ʻia i nā huʻa polyurethane. Me ka hoʻonui ʻana o ka manaʻo honua i ka hōʻemi ʻana i ka hopena o ke kaiapuni, ke lilo nei nā HFO i koho makemake ʻia no nā noi like ʻole, e pani ana i nā hydrofluorocarbons kahiko (HFCs) ma muli o ko lākou ʻano kaiapuni maikaʻi.

He aha ka HFO?

ʻO nā HFO kahi papa o nā hui i hoʻohana nui ʻia e like me nā refrigerants, nā mea puhi, nā propellants, a me nā solvents. I loko o nā ʻōnaehana hua polyurethane, lawelawe nā HFO ma ke ʻano he mau mea puhi e kōkua i ka hana ʻana i ke ʻano cellular o nā hua, e hāʻawi ana i ko lākou mau waiwai insulation, rigidity, a me ke kūpaʻa.

Ua kaulana nā HFO i ka wā i hoʻopau ʻia ai nā HFC e like me nā lula honua e pili ana i ka hōʻemi ʻana i nā mea me ka hiki ke hoʻomehana honua kiʻekiʻe (GWP). ʻOiai ua hoʻohana nui ʻia nā HFC, e like me HFC-245fa, i nā ʻōnaehana huʻa, loaʻa iā lākou kahi GWP kiʻekiʻe a kōkua i ka hoʻopau ʻana o ka ozone. I ka hoʻohālikelike ʻana, ʻaʻohe o nā HFO i ka hiki ke hoʻopau ʻana o ka ozone (ODP) a me nā waiwai GWP haʻahaʻa loa, e lilo ana lākou i koho ʻē aʻe e hoʻomau ʻia.

Nā Pōmaikaʻi o nā ʻōnaehana HFO Foaming

1. Ka hopena haʻahaʻa o ke kaiapuniʻO ka pōmaikaʻi nui o nā HFO ʻo ia ko lākou hopena liʻiliʻi loa i ke kaiapuni. ʻAʻohe ODP o nā HFO a he haʻahaʻa loa ka GWP, kahi e kōkua ai i ka hōʻemi ʻana i nā hoʻokuʻu kinoea ʻōmaʻomaʻo.
2. Ka Pono o ka IkehuHōʻike nā huʻa HFO i nā waiwai insulation maikaʻi loa, e hoʻonui ana i ka pono o ka ikehu o nā noi e like me nā pahu hau, nā pahu hau, nā insulation huʻa pīpī, a me nā mea kūkulu hale.
3. Palekana a me ka VersatilityʻAʻole hiki ke lapalapa nā HFO, ʻaʻohe mea ʻawahia, a hāʻawi i ka versatility ma nā ʻōnaehana huʻa like ʻole, me nā huʻa paʻa a maʻalahi hoʻi. He kūpono loa lākou no nā ʻōnaehana e hoʻohana ana i ka wai ma ke ʻano he mea puhi pū, e hōʻemi hou ana i ka hilinaʻi ʻana i nā mea kemika kuʻuna.
4. Nā Waiwai Huʻa i Hoʻomaikaʻi ʻiaHāʻawi nā HFO i kahi ʻano cell maikaʻi a like i loko o nā huʻa polyurethane, kahi e kōkua ai i ka mālama ʻana i ka ikaika mechanical, ke kūpaʻa dimensional, a me ka hana huʻa holoʻokoʻa. Hoʻemi pū lākou i ka brittleness huʻa, hoʻomaikaʻi i ka hoʻōla ʻana o ka ʻili, a hoʻoikaika i ka hoʻopili ʻana ma waena o nā substrates.

ʻO ka wā e hiki mai ana o nā HFO i nā Polyurethane Foams

I ka hoʻomau ʻana o ka ulu ʻana o ke koi honua no nā mea e pili ana i ke kaiapuni a me ka ikehu, manaʻo ʻia e lilo nā ʻōnaehana huʻa HFO i mea koʻikoʻi loa i ka ʻoihana huʻa polyurethane. ʻO ka hoʻololi ʻana mai HFCs a i HFOs ʻaʻole wale ia e kūlike me nā lula kaiapuni akā hōʻoia pū kekahi e hiki i nā mea hana ke hoʻomau i ka hana ʻana i nā huʻa hana kiʻekiʻe me ka hoʻemi ʻana i ka hopena kaiapuni.

Ma kā mākou hui, ua kūpaʻa mākou i ka hoʻolaha ʻana i ka ʻenehana catalyst polyurethane e kākoʻo i nā ʻōnaehana hoʻohua HFO.Mea hoʻonui MXC-70, i hoʻolālā kūikawā ʻia no ka hoʻohana ʻana me nā ʻōnaehana HFO-based, hoʻomaikaʻi i ka hoʻōla ʻana o ka ʻili, paipai i ka piʻi mālie ʻana, a hoʻomaikaʻi i ka hoʻopili ʻana o ka substrate. He kūpono loa ia no nā ʻōnaehana e hoʻohana ana i ka wai ma ke ʻano he mea puhi pū, e hāʻawi ana i ka maʻalahi a me nā hoʻokuʻu haʻahaʻa i nā noi huʻa maʻalahi a paʻa.

Inā makemake ʻoe i nā ʻōnaehana hua HFO a i ʻole kā mākouMea hoʻonui MXC-70, e ʻoluʻolu e hoʻokaʻaʻike mai iā mākou no ka ʻike hou aku mainfo@mingxuchem.com.
