I-PTFE egcwalisiweyo-Izinto ezigcweleyo

Iglasi, iKhabhoni, iBronzi, iGrafite……

I-PTFE ezaliswe yiglasi

PTFEiqiniswa ngeentsinga zeglasi, ipesenti yohluka phakathi kwe-5 kunye ne-40%.Ifiber yeglasi eyongeziweyo iphucula iipropati zokunxiba kwaye, kwinqanaba elincinci, kunye namandla okuguqula phantsi komthwalo ngelixa ishiya ingatshintshi kakhulu iimpawu zombane kunye neekhemikhali.Iglasi ngokwayo, inoxhathiso olulambathayo ngokuchasene nealkali kwaye ihlaselwa lula yihydrofluoric acid.I-coefficient of friction inyuswe kancinci kwaye ngenxa yesi sizathu, igraphite ngamanye amaxesha yongezwa ukuhlawulela le mpembelelo yecala.Thenga iGlass ezaliswe yiPTFE kwi-intanethi

I-PTFE ezaliswe yiKhabhoni

Ikhabhoni yongezwa kwi-PTFE ngepesenti ngobunzima phakathi kwe-10 kunye ne-35%, kunye nepesenti encinci yegraphite.Kwakhona, ikhabhoni ithande ukuphucuka ukuya kuthi ga kwinqanaba elikhulu, ukunxiba kunye namandla okuguqula, ngelixa ishiya phantse ingatshintshanga ukuxhathisa imichiza, kodwa iguqula kakhulu iipropathi zombane.Thenga iCarbon ezaliswe yi-PTFE kwi-intanethi

I-PTFE ezaliswe ngeBronzi

Ubhedu, xa lusetyenziswa njengesizaliso, longezwa ngeepesenti zobunzima phakathi kwama-40 nama-60%.I-PTFE ezaliswe ngebronzi ineyona mpahla igqwesileyo yokunxiba, amandla oguquko amangalisayo kunye ne-thermal conductivity elungileyo, kodwa iimpawu zombane ezimbi kunye nokuxhathisa imichiza.

I-graphite ezaliswe yi-PTFE

Iipesenti ezisetyenzisiweyo zahluka phakathi kwe-5 kunye ne-15%.Igraphite yehlisa i-coefficient of friction kwaye, ke ngoko, ihlala idityaniswa kwezinye iindidi ze-PTFE ezizalisweyo zokuphucula le propati.Iphucula i-deformation phantsi komthwalo, amandla kwaye, kwinqanaba elincinci, iimpawu zokugqoka.

Ezinye IiFili ezifumanekayo

I-Molybdenum sulphide, nangona inciphisa i-coefficient of friction, ngamanye amaxesha ikhethwa ngaphezu kwegraphite.Ezinye i-powders zetsimbi (insimbi engenasici, i-nickel, i-titanium), ngokuqwalasela ukuchasana kwazo ngokukodwa kwii-agent zekhemikhali, ngamanye amaxesha zisetyenziswa njengezizaliso ze-PTFE, nangona ukuxhatshazwa kwabo, ngokubhekiselele kwi-bronze, kuphantsi.I-oxides yesinyithi, eyongeziweyo kwezinye iifayili, inika iimpawu ezingcono zokunxiba.
