I-PTFE egcwele - Izinto ezigcwele

Ingilazi,Ikhabhoni,Ithusi,iGraphite……

I-PTFE Egcwele Ingilazi

I-PTFEiqiniswa ngemicu yengilazi, iphesenti lihluka phakathi kuka-5 no-40%.I-fiber yengilazi eyengeziwe ithuthukisa izakhiwo zokuguga futhi, ngezinga elincane, namandla okuguqulwa ngaphansi komthwalo ngenkathi ishiya ingashintshiwe kakhulu izici zikagesi namakhemikhali.Ingilazi ngokwayo, inokumelana okungekuhle ngokumelene nama-alkali futhi ihlaselwa kalula yi-hydrofluoric acid.I-coefficient of friction yanda kancane futhi ngenxa yalesi sizathu, i-graphite ngezinye izikhathi iyanezelwa ukuze kunxeshezelwe lo mphumela ohlangothini.Thenga i-PTFE Egcwele Ingilazi ku-inthanethi

I-PTFE Egcwele Ikhabhoni

Ikhabhoni yengezwa ku-PTFE ngephesenti ngesisindo esiphakathi kuka-10 no-35%, kanye nephesenti elincane legraphite.Futhi, ikhabhoni ijwayele ukuthuthuka ngokwezinga elithile, amandla okuguga namandla okuguquka, kuyilapho ishiya cishe ingaguquki ukumelana namakhemikhali, kodwa iguqula kakhulu izakhiwo zikagesi.Thenga i-PTFE Egcwele Ikhabhoni ku-inthanethi

I-PTFE Egcwele Ibhulonzi

I-bronze, lapho isetshenziswa njengokugcwalisa, yengezwa ngamaphesenti esisindo phakathi kuka-40 no-60%.I-PTFE egcwele ithusi inezinto ezigqokwa kahle kakhulu, amandla okuguga aphawulekayo kanye nokuhamba kahle kwe-thermal, kodwa izici zikagesi ezingezinhle nokumelana namakhemikhali.

I-graphite Igcwaliswe i-PTFE

Amaphesenti asetshenzisiwe ayahluka phakathi kuka-5 no-15%.Igraphite yehlisa i-coefficient of friction futhi, ngakho-ke, ivamise ukungezwa kwezinye izinhlobo ze-PTFE egcwalisiwe ukuze kuthuthukiswe lesi sakhiwo.Ithuthukisa i-deformation ngaphansi komthwalo, amandla futhi, ngezinga elincane, izakhiwo zokugqoka.

Amanye Ama-Filler Atholakalayo

I-Molybdenum sulphide, nakuba inciphisa i-coefficient of friction, ngezinye izikhathi ikhethwa kune-graphite.Ezinye izimpushana zensimbi (insimbi engagqwali, i-nickel, i-titanium), uma kucatshangelwa ukumelana kwazo okukhethekile nama-ejenti amakhemikhali, ngezinye izikhathi zisetshenziswa njengezigcwalisi ze-PTFE, nakuba ukumelana kwazo nokugqoka, maqondana nethusi, kuphansi.Ama-oxide ensimbi, angezwe kwamanye ama-filler, anikeza izakhiwo ezingcono zokugqoka.
