Njengoba sonke sazi, intengo ye-fkm (fluoroelastomer) ikhuphuke kakhulu ngo-2021. Futhi yafinyelela entengo ephezulu ekupheleni kuka-2021. Wonke umuntu wayecabanga ukuthi izokwehla ngonyaka omusha. NgoFebhuwari 2022, intengo ye-fkm eluhlaza yabonakala iphansi kancane. Ngenkathi ngemva kwalokho, imakethe inolwazi olusha mayelana nokuthambekela kwentengo. Kungase kungehli kakhulu njengoba besibikezele. Ngokuphambene nalokho, intengo ephezulu izohlala isikhathi eside. Futhi isimo esibi kakhulu ukuthi izophinde ikhuphuke. Kungani lokhu kuzokwenzeka?
Isidingo se-PVDF esingasetshenziswa kuma-cathode ebhethri le-lithium sikhula kakhulu. Ngokusho kwemibiko, isidingo somhlaba wonke se-PVDF sama-cathode ebhethri le-lithium ngo-2021 sasingamathani ayi-19000, kanti ngo-2025, isidingo somhlaba wonke sizoba ngamathani ayi-100 000! Izidingo ezinkulu zibangela ukuthi intengo yezinto zokusetshenziswa eziphezulu i-R142 ikhuphuke kakhulu. Kuze kube namuhla intengo ye-R142b isakhula. I-R142b nayo iyi-monomer ye-fluoroelastomer. I-general copolymer fluoroelastomer i-polymerized yi-VDF (vinylidene fluoride) kanye ne-HFP (hexafluoropropylene). Ngaphambi kukaSepthemba 2021, intengo ye-copolymer raw gum cishe ingama-$8-$9/kg. Kuze kube nguDisemba 2021 intengo ye-copolymer raw gum ingu-$27~$28/kg! Imikhiqizo yamazwe ngamazwe efana ne-Solvay Daikin kanye ne-Dupont ishintsha ukugxila ibe yibhizinisi elinenzuzo kakhulu. Ngakho-ke ukushoda kuyanda. Izidingo eziphezulu kanye nentengo eqhubekayo ekhuphukayo kubangela ukuthi intengo ye-fluoroelastomer iqhubeke ikhuphuka futhi ngeke yehle isikhathi eside.
Muva nje umhlinzeki omkhulu we-fkm raw gum uyeka ukuhlinzeka nge-fkm. Kanti omunye umhlinzeki usememezele ukwenyuka kwentengo kakade. Njengoba kuqubuke i-COVID muva nje eShayina, sicabanga ukuthi intengo ephezulu izohlala isikhathi eside. Sicela uxhumane nethimba lethu lokuthengisa ukuze uthole intengo ebuyekeziwe futhi ulungise amasheya akho ngendlela efanele. Ngiyethemba ukuthi singadlula ezikhathini ezinzima sibambene.
Isikhathi sokuthunyelwe: Meyi-16-2022
