I-PTFE yaziwa ngokuzinza kwayo nokumelana namakhemikhali amaningi.… Lokhu kuyenza ibe yimpahla eguquguqukayo, futhi sibumba, sakhe izingxenye zemishini kule nto.
Ngokuvamile, i-PTFE icutshungulwa ibe yizimo eziqediwe ngokucindezelwa noma amasu okubumba aso-static.I-PTFE resin esesimweni sempushana (ehlanzekile noma ehlanganiswe nezigcwalisi) icindezelwa ibe yisikhunta esandulela isimo lapho izinga lokushisa lisendaweni.Ngemva kokususwa esikhunjeni, induku noma ithubhu esenziwe ngaphambilini iyashiswa kuhhavini futhi ifakwe i-sintered.Phakathi nale nqubo ithola amandla ayo okuhlanganisa ukuze isetshenziswe ekugcineni.Ngokukhiqizwa kwezingxenye zevolumu ephezulu, umumo we-PTFE akhiwa abe ubude obuqhubekayo ngokusebenzisa i-ram-extrusion.Inqama ye-hydraulic ihamba iye emuva naphambili, isunduza futhi icindezela i-PTFE powder ngokusebenzisa iphrofayili ye-extrusion ngenkathi ishiswa futhi ifakwe nge-sinter ngesikhathi esifanayo.Kusukela endongeni eqedwe kancane noma ishubhu, izimpawu ze-PTFE eziqediwe zikhiqizwa ngokunemba-machining.
I-PTFE powder, umumo oqedwe kancane kanye nomkhiqizo wokugcina owenziwe ngomshini
Ezinye izinto ezijwayelekile ze-polymeric kanye nobubanzi bokusebenza kwazo:
