Msika wa PTFE

Polytetrafluoroethylene (PTFE) ndi polima wa tetrafluoroethylene (TFE), chomwe ndi chinthu chofunikira kwambiri cha organic fluorine chokhala ndi dielectric yabwino kwambiri komanso kugundana kocheperako.Kawirikawiri amagwiritsidwa ntchito ngati mapulasitiki a uinjiniya, amatha kupangidwa kukhala polytetrafluoroethylene chubu, ndodo, tepi, mbale, filimu, ndi zina zotero, m'makampani, moyo wa tsiku ndi tsiku ndi madera ena amagwiritsidwa ntchito kwambiri, ali ndi mbiri ya "mfumu ya pulasitiki".

M'zaka zaposachedwapa, mowa padziko lonse wa PTFE wakula mofulumira, kufika pafupifupi 70% ya okwana kumwa fluorine utomoni.Kuyambira 2010, China yatsagana ndi kusintha kwa PTFE kupanga mphamvu yapamwamba komanso yapadera m'mayiko otukuka, ndipo ena mwa mphamvu zake zotsika za PTFE zasamukira ku China.

Pakalipano, China yakhala ikutulutsa PTFE padziko lonse lapansi.Akuti mphamvu yaku China ya TEflon mu 2020 idzakhala matani 149,600, ndikuzindikira matani 97,200 opanga, zomwe zikuwerengera pafupifupi 60% ya msika wapadziko lonse lapansi.
