PTFEyifluoropolymer ethambileyo, engeyotyhefu enomlinganiso ophantsi kakhulu wokukhuhlana, okuthetha ukuba imathiriyeli embalwa enamathela kuyo, kwaye uninzi oluncamathelayo lunochutywa okanye lukhuhlwe.I-PTFE ikwanazo nemichiza ebalaseleyo kunye nokumelana nemozulu.I-PTFE ayinyibiliki kwizinto ezininzi eziphilayo kwaye ineempawu ezibalaseleyo zombane.Ihlala izinzile kuzo zombini i-cryogenic kunye neqondo lokushisa eliphakamileyo (ukusuka -400 ° F ukuya kwi-500 ° F), nangona iimpawu zayo zomatshini ziphantsi xa kuthelekiswa nezinye iiplastiki zobunjineli.Iipropati zomatshini, zombane kunye ne-thermal ze-PTFE zinokuphuculwa ngokongeza izihluzi ezifana nefiber yeglasi, i-carbon, igraphite, ibronze kunye ne-molybdenum disulfide (MoS2).Usetyenziso oluqhelekileyo lubandakanya amatywina, iibheringi, amahlahla, izahluli zeekhoyili, iitheminali, kunye nemibhobho eqinileyo kunye nezinto ezifakelwayo.
I-PTFE yinkcazelo yemichiza ye-polytetrafluoroethylene, okanye eyaziwa ngokuba yi-DuPont's polymer.Abanye ababoneleli abaninzi nabo benza i-PTFE grannular kunye neereyini ezihamba simahla.
I-TFE ligama lekhemikhali ye-tetrafluoroethylene, eyigesi engenambala nengenarhasi, inetyhefu egqithisileyo kwaye ekugqibeleni iyabulala.
Musa ukubhidanisa ezi zimbini, nangona ishishini leplastiki lisebenzise kakubi le migaqo kule minyaka idlulileyo.
I-TFE yi-monomer yangaphambili yokwenza i-PTFE.Ke ndicinga ukuba abakhange bazikhathaze ngo'P'.I-FEP kunye ne-PFA zezinye iintlobo ezimbini eziqhelekileyo zepolymer.Zinyibilika ziqhubekeke ngelixa i-PTFE ingekho.Zonke iinguqu ngokuqhelekileyo kunzima ukuzidibanisa.Amaqhinga aqhelekileyo asetyenziswayo ukwenza ibhondi kukufakwa kweekhemikhali (mhlawumbi into ozama ukuyenza), ukufakwa kweplasma kwangaphambili, unyango lwe-corona, njl.
Unokujonga kwakhona iimveliso zethu zePTFE (intonga ye-ptfe, ityhubhu ye-ptfe, i-tubing kunye nombhobho) isampuli yasimahla.
