Ni iyihe biciro bya fluoroelastomer bizamuka mu mwaka wa 2022?

Nkuko twese tubizi, igiciro cya fkm (fluoroelastomer) cyazamutse cyane mu 2021. Kandi cyageze ku giciro cyo hejuru mu mpera za 2021. Buri wese yatekerezaga ko kizagabanuka mu mwaka mushya. Muri Gashyantare 2022, igiciro cya fkm cyasaga nkaho kiri hasi cyane. Mu gihe nyuma y'ibyo, isoko rifite amakuru mashya yerekeye uko ibiciro bigenda. Bishobora kutagabanuka cyane nk'uko twabiteganyaga. Ahubwo, igiciro cyo hejuru kizagumaho igihe kirekire. Kandi ikibazo kibi cyane ni uko kizongera kwiyongera. Kuki ibi bizaba?

Ubusabe bwa PVDF bushobora gukoreshwa muri cathode za bateri ya lithiamu buriyongera cyane. Nk’uko raporo zibigaragaza, ubusabe bwa PVDF ku isi hose bwa cathode za bateri ya lithiamu mu 2021 bwari toni 19000, kandi mu 2025, ubusabe ku isi yose buzaba toni ibihumbi 100! Ubusabe bwinshi butuma igiciro cy’ibikoresho fatizo bya R142 kizamuka cyane. Kugeza uyu munsi igiciro cya R142b kiracyariyongera. R142b nayo ni monomer ya fluoroelastomer. Copolymer fluoroelastomer rusange ikorwa na VDF (vinylidene fluoride) na HFP (hexafluoropropylene). Mbere ya Nzeri 2021, igiciro cya copolymer raw gum kiri hagati ya $8-$9/kg. Kugeza mu Ukuboza 2021 igiciro cya copolymer raw gum cyari $27~$28/kg! Ibirango mpuzamahanga nka Solvay Daikin na Dupont birimo guhindura ubwiyongere bw’ubucuruzi. Kubera iyo mpamvu, ubuke burimo kwiyongera. Ibikenewe byinshi n'igiciro kikomeje kuzamuka bituma igiciro cya fluoroelastomer gikomeza kwiyongera kandi ntikigabanuka igihe kirekire.

Vuba aha, umucuruzi mukuru w’ibinyobwa bya fkm yahagaritse gutanga fkm. Undi mucuruzi yamaze gutangaza ko ibiciro byazamutse. Kubera icyorezo cya COVID giherutse mu Bushinwa, dutekereza ko igiciro kiri hejuru kizaramba. Nyamuneka hamagara itsinda ryacu rishinzwe kugurisha kugira ngo ubone igiciro gishya kandi uhindure imigabane yawe neza. Twizere ko dushobora guhangana n’ibihe bigoye dufatanyije.
