He aha ke ʻano o ke kumukūʻai o ka fluoroelastomer i ka makahiki 2022?

E like me kā kākou e ʻike nei, ua piʻi nui ke kumukūʻai o ka fkm (fluoroelastomer) i ka makahiki 2021. A ua hiki i ke kumukūʻai kiʻekiʻe loa i ka hopena o 2021. Ua manaʻo nā mea a pau e iho ana i ka makahiki hou. I Pepeluali 2022, ua emi iki ke kumukūʻai maka o ka fkm. Ma hope o kēlā, loaʻa i ka mākeke ka ʻike hou e pili ana i ke ʻano o ke kumukūʻai. ʻAʻole paha e emi nui e like me kā mākou i wānana ai. Ma ke ʻano ʻē, e mau ke kumukūʻai kiʻekiʻe no ka manawa lōʻihi. A ʻo ke kūlana ʻino loa e piʻi hou ana. No ke aha e hana ʻia ai kēia?

Ke piʻi nui nei ke koi o PVDF hiki ke hoʻohana ʻia i loko o nā cathodes pākahiko lithium. Wahi a nā hōʻike, ʻo ke koi honua no PVDF no nā cathodes pākahiko lithium i ka makahiki 2021 he 19000 tons, a ma ka makahiki 2025, e like me 100 tausani tons ke koi honua! ʻO nā koi nui ke kumu o ke kumukūʻai o ka mea maka mua ʻo R142 e piʻi nui ana. A hiki i kēia lā ke piʻi mau nei ke kumukūʻai o R142b. ʻO R142b kekahi monomer o ka fluoroelastomer. Hoʻopili ʻia ka fluoroelastomer copolymer laulā e VDF (vinylidene fluoride) a me HFP (hexafluoropropylene). Ma mua o Kepakemapa 2021, ʻo ke kumukūʻai o ka copolymer raw gum ma kahi o $8-$9/kg. A hiki i Dekemaba 2021, ʻo ke kumukūʻai o ka copolymer raw gum he $27~$28/kg! Ke hoʻololi nei nā lama honua e like me Solvay Daikin lāua ʻo Dupont i ka nānā ʻana i ka ʻoihana ʻoi aku ka waiwai. No laila, ke piʻi nei ka hemahema. ʻO ke kiʻekiʻe o nā koi a me ke piʻi mau nei o ke kumukūʻai e hoʻomau nei ke piʻi ʻana o ke kumukūʻai o ka fluoroelastomer a ʻaʻole e iho i lalo no ka manawa lōʻihi.

I kēia mau lā iho nei, ua hoʻōki kekahi mea hoʻolako nui o ka fkm i ka hāʻawi ʻana iā fkm. A ua hoʻolaha mua kekahi mea hoʻolako i ka piʻi ʻana o ke kumukūʻai. Me ka maʻi ahulau COVID ma Kina i hala koke aku nei, manaʻo mākou e mau ana ke kumukūʻai kiʻekiʻe. E ʻoluʻolu e kelepona i kā mākou hui kūʻai aku no ke kumukūʻai hou a hoʻoponopono i kāu mau waihona me ke kūpono. Manaʻolana e hiki iā mākou ke lanakila i nā manawa paʻakikī me ka lima.
