Iipropati ezizaliswe yi-PTFE

PTFE(I-PolyTetraFluoroEthylene), ipholima esekwe ku-fluorocarbon, ikwabizwa ngokuba yi-Dupont's brand name polymer® kunye negama lebhrendi likaFuron iRulon®.Iqhele ukusetyenziswa kwimo yayo enyulu (engazaliswanga).

IVirgin PTFE iyakwazi ngokwayo, kodwa xa izigcwalisi zongezwa, iphucula ukunxitywa kwezinto ezibonakalayo kunye neempawu zoguquko ukuze zisebenzise ngokupheleleyo indibaniselwano yazo eyodwa yeekhemikhali, iipropathi zomzimba kunye nombane.

Awona mabanga azaliswe axhaphakileyo kunye neziphumo zawo eziphuculweyo zomatshini zezi:

IFayibha yeglasi(PTFE-GF): Ifakwe kwiimali ezahlukeneyo (5% ukuya kwi-40%), yandisa amandla oxinzelelo, ukuqina kunye nokugqoka;kunciphisa ukuhamba kunye nokuhamba okubandayo;impembelelo encinci kwiimpawu zeekhemikhali kunye nombane.

Ikhabhoni(PTFE-CF): Ifakwe kwiimali ezahlukeneyo (10% ukuya kwi-35%), inyusa amandla oxinzelelo, ubunzima, ukunxiba, kunye neempawu zomthwalo;ukumelana kakuhle kweekhemikhali;Iindidi ezahlukeneyo kunye nezixa zekhabhoni zingongezwa ukuguqula ukuhanjiswa.

Igraphite(PTFE-CGF): Ifakwe kwiimali ezahlukeneyo (5% ukuya kwi-15%), iyanciphisa i-coefficient of friction;kunciphisa ukunxiba kokuqala;kwandisa amandla.

I-Molybdenum Disulfide(PTFE-MoS2): Yongezwa kwiimali ezahlukeneyo (5% ukuya kwi-15%), yandisa ubunzima, ukuqina, kunye nokugqoka;impembelelo encinci kwiimpawu zeekhemikhali kunye nombane.

Isinyithi(PTFE-BR, PTFE-SSF): Iipropati zokunxiba ezigqwesileyo, amandla amangalisayo oguquko kunye nokuhanjiswa kakuhle kwe-thermal.

Izimbiwa:I-Mica yongezwa kwiimali ezahlukahlukeneyo (i-5% ukuya kwi-10%), inikezela ngokugqwesileyo kokugqoka kunye nokuzinza ngaphezu kokuthotyelwa kwe-FDA.

Usetyenziso

• * Ukumelana neekhemikhali ezigqwesileyo kunye ne-hydrolysis)
