Njengoba sonke sazi, intengo ye-fkm (fluoroelastomer) ikhuphuka kakhulu ngo-2021. Futhi ifinyelele inani eliphakeme 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. Ingase ingehli kakhulu njengoba besibikezele. Ngokuphambene nalokho, intengo ephezulu izogcina isikhathi eside impela. Futhi isimo esibi kakhulu ukuthi kuzokwanda futhi. Kungani lokhu kuzokwenzeka?
Isidingo se-PVDF esingasetshenziswa kumabhethri e-lithium cathode sikhula kakhulu. Ngokusho kwemibiko, isidingo somhlaba wonke se-PVDF se-lithium battery cathode ngo-2021 sasingamathani angu-19000, futhi ngo-2025, isidingo somhlaba wonke sizoba amathani ayizinkulungwane eziyi-100! Izimfuno ezinkulu zenza intengo yezinto ezingavuthiwe ezikhuphuka nomfula u-R142 inyuke kakhulu. Kuze kube namuhla intengo ka-R142b isakhuphuka. I-R142b futhi iyi-monomer ye-fluoroelastomer. I-copolymer fluoroelastomer evamile yenziwa i-polymerized yi-VDF (vinylidene fluoride) ne-HFP (hexafluoropropylene) Ngaphambi kukaSepthemba 2021, intengo ye-copolymer raw gum icishe ibe ngu-$8-$9/kg. Kuze kube nguDisemba 2021 inani le-copolymer gum eluhlaza ngu-$27~$28/kg! Imikhiqizo yamazwe ngamazwe njenge-Solvay Daikin ne-Dupont ishintsha ukugxila kwebhizinisi elinenzuzo eyengeziwe. Ngakho-ke ukuntuleka kuyanda. Izimfuno eziphezulu kanye nentengo elokhu ikhuphuka kudala intengo ye-fluoroelastomer ilokhu ikhuphuka futhi ngeke yehle isikhathi eside.
Muva nje umphakeli oyedwa omkhulu we-fkm raw gum uyeka ukunikeza i-fkm. Futhi omunye umphakeli usememezele ukwenyuka kwentengo kakade. Ngokuqubuka kwakamuva kwe-COVID eChina, sicabanga ukuthi intengo ephezulu izohlala. Sicela uxhumane nethimba lethu labadayisi ukuze uthole amanani abuyekeziwe futhi ulungise izitoko zakho ngokunengqondo. Ngethemba ukuthi singadlula ezikhathini ezinzima sibambene ngezandla.
