He aha ke kumu kūʻai o ka fluoroelastomer i 2022?

E like me kā mākou e ʻike ai, piʻi nui ke kumukūʻai fkm (fluoroelastomer) i 2021. A hiki i ke kumukūʻai kiʻekiʻe ma ka hopena o 2021. Ua manaʻo nā kānaka a pau e iho i ka makahiki hou. I Fepeluali 2022, ua emi iki ke kumu kuai fkm maka. ʻOiai 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. ʻO ka mea ʻē aʻe, e mālama ʻia ke kumukūʻai kiʻekiʻe no ka manawa lōʻihi. A ʻo ke kūlana ʻino loa e hoʻonui hou ʻia. No ke aha e hiki mai ai kēia?

Ke piʻi nui nei ke koi o PVDF hiki ke hoʻohana ʻia i nā cathodes pākahi lithium. Wahi a nā hōʻike, ʻo ka noi honua no PVDF no nā cathodes pākahi lithium i 2021 he 19000 tons, a ma 2025, e pili ana ka noi honua ma kahi o 100 tausani tons! ʻO nā koi nui ke kumu o ke kumu kūʻai o ka mea maka mua 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 copolymer fluoroelastomer maʻamau 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 ke kumu kūʻai o ka copolymer raw gum he $27~$28/kg! Ke hoʻololi nei nā brand International e like me Solvay Daikin a me Dupont i ka ʻoihana ʻoi aku ka maikaʻi. No laila ke mahuahua nei ka hemahema. ʻO nā koi kiʻekiʻe a me ka piʻi ʻana o ke kumukūʻai ke kumu e piʻi mau ai ke kumukūʻai o ka fluoroelastomer a ʻaʻole e iho i lalo no ka manawa lōʻihi.

I kēia mau lā, ua ho'ōki kekahi mea hoʻolako fkm maka i ka hoʻolako ʻana i ka fkm. A ua hoʻolaha mua kekahi mea hoʻolako i ka piʻi ʻana o ke kumukūʻai. Me ka make ʻana o COVID i Kina, manaʻo mākou e mau ke kumukūʻai kiʻekiʻe. E ʻoluʻolu e kelepona i kā mākou hui kūʻai aku no ke kumukūʻai hou a hoʻoponopono pono i kāu mau waiwai. Manaʻolana e hiki iā mākou ke hele i nā manawa paʻakikī me ka lima lima.
