PTFE ndi chiyani?

Tiyeni tiyambe kufufuza kwathu kwa Teflon vs PTFE ndikuwunika bwino zomwe PTFE ili. Kupereka mutuwo wathunthu, polytetrafluoroethylene ndi polima yopanga yokhala ndi zinthu ziwiri zosavuta; carbon ndi fluorine. Amachokera ku tetrafluoroethylene (TFE) ndipo ali ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zothandiza pazinthu zosiyanasiyana. Mwachitsanzo:

• Malo osungunuka kwambiri: Ndi malo osungunuka a 327 ° C, pali zochitika zochepa kwambiri zomwe PTFE ingawonongeke ndi kutentha.
• Hydrophobia: Kukana madzi kumatanthawuza kuti sikunyowa, kumapangitsa kuti ikhale yothandiza kuphika, kuvala mabala ndi zina.
• Opanda mankhwala: Zambiri zosungunulira ndi mankhwala sizidzawononga PTFE.
• Low coefficient of kukangana: The coefficient of friction of PTFE ndi imodzi mwazotsika kwambiri zamtundu uliwonse, kutanthauza kuti palibe chomwe chidzamamatire.
• High flexural mphamvu: Kukhoza kupindika ndi kusinthasintha, ngakhale kutentha kochepa, kumatanthauza kuti chitha kugwiritsidwa ntchito mosavuta pazinthu zosiyanasiyana popanda kutaya umphumphu.

Kodi Teflon ndi chiyani?

Teflon kwenikweni anapezeka mwangozi, ndi wasayansi wotchedwa Dr. Roy Plunkett. Anali kugwira ntchito ku DuPont ku New Jersey akuyesera kupanga firiji yatsopano, pamene adawona kuti mpweya wa TFE unatuluka m'botolo lomwe ankagwiritsa ntchito, koma botolo silinali lolemera. Pofuna kudziwa chomwe chimayambitsa kulemera kwake, adafufuza mkati mwa botololo ndipo adapeza kuti linali lopangidwa ndi phula, loterera komanso lolimba modabwitsa, lomwe tsopano tikudziwa kuti ndi Teflon.

Zomwe zili bwino mu Teflon vs PTFE?

Ngati mwakhala mukumvetsera mpaka pano, mudziwa kale zomwe tinena pano. Palibe wopambana, palibe mankhwala abwinoko ndipo palibe chifukwa chofanizira zinthu ziwirizi. Pomaliza, ngati mukudabwa za Teflon vs PTFE, musadabwenso, chifukwa, kwenikweni, ndi chinthu chimodzi, chosiyana ndi dzina lokha komanso china chilichonse.
