Kwiimveliso ze-PTFE, zizalisweIimveliso ze-PTFEzezona mveliso inkulu, kumazwe angaphandle ezaliswe PTFE ngokubanzi igqitywe PTFE resin imveliso yesityalo, ezifana Germany Hoechst HosTaflonTF4000 series, HosTaflonTF3000 series kunye HosTaflon2000 series.E-China, ekubeni i-PTFE iteknoloji yokuvelisa i-resin isala emva kobugcisa bokucubungula, iteknoloji yokuzalisa i-PTFE yenziwa kwiplanti yokulungisa imveliso.Ngokudibanisa iifayili ezahlukeneyo ezifana ne-inorganic, isinyithi kunye ne-polymer kwi-resin ye-PTFE ukuphucula ukunyanzeliswa koxinzelelo, ukuxhathisa ukunxiba, ukumelana nokuhamba okubandayo, ukumelana nobushushu, ukuzinza kwe-PTFE.Iimveliso ezizaliswe ngokupheleleyo xa kuthelekiswa ne-PTFE ecocekileyo, ukunyanzeliswa koxinzelelo kwanda ngama-5 ukuya kwamaxesha e-10, ukuxhathisa ukunxiba kwanda ngamaxesha e-1000, i-coefficient yokwandiswa komgca kuncitshiswe ngama-80%, i-thermal conductivity yanda ngamaxesha e-5, kwaye inciphisa ukuxhathisa umthamo kunye nokumelana nomphezulu, ngokukodwa. isetyenziswe kumashishini omatshini kwiibheringi zokuthambisa i-oyile-free, ukuthwala i-bushings, i-piston rings, izikhokelo zesixhobo somatshini, njl. Kwiminyaka yakutshanje, i-anti-corrosion yangaphandle yeekhemikhali, ezaliswe yi-PTFE njengombhobho, iivalve, iimpompo, njl njl. i-lining iphuhla ngokukhawuleza, indawo entsha yesicelo ye-PTFE egcweleyo.
Ngokwezi mfuno zisetyenziswa ngokuqhelekileyo izihluzi: i-glass fiber, i-carbon fiber, igraphite, isanti ye-quartz, i-molybdenum disulfide, i-amorphous carbon, i-calcium fluoride, umgubo wobhedu, i-ceramics, i-polyimide, i-polyphenylene, i-poly-p-hydroxyformate njalo njalo.
Iimveliso ezigcwalisiweyo zePTFE zibunjwa ngokubanzi: umgangatho wokugcwaliswaIimveliso ze-PTFEkuxhomekeke ekukhethweni kwe-resin filler, uyilo lwefomula, iqondo le-homogeneity yokuxuba izinto kunye nezinye izinto.Okwangoku kukho iindlela ezintathu zokuxuba ezisetyenziselwa ukuzalisa i-PTFE: (1) inkqubo yokuxuba eyomileyo idinga ukukhawuleza, i-uniform yokuxuba isixhobo ngaphandle kwendawo efileyo, esebenzayo kwiimfuno eziqhelekileyo zemveliso.(2) ukuxutywa kwe-solvent, i-solvent yi-acetone okanye i-methanol, i-PTFE egcwele iglasi.Uxinzelelo lokubumba lweemveliso ze-PTFE ezizaliswe kuxhomekeke kubungakanani bomthamo we-filler kwi-PTFE, njengale: kunye ne-5% yoxinzelelo lokubumba lwe-filler ye-bar ye-250;kunye ne-6% ukuya kwi-10% yoxinzelelo lokubumba umhluzi we-350 bar;kunye ne-12% ukuya kwi-25% yoxinzelelo lokubumba lokugcwalisa i-bar ye-500;ngoxinzelelo olungaphezulu kwe-25% yokubumba i-filler ye-700 bar.Inkqubo ye-sintering yeemveliso ezigcwalisiweyo iyafana neye-PTFE esulungekileyo.Kodwa iimveliso ezigcwalisiweyo eziqulathe i-MoS2 zifuna ukucwiliswa kumoya ophakathi kwi-360℃, okanye ukuntywilwa kwi-nitrogen medium kuma-380℃.Iimveliso ezigcwalisiweyo eziqulethe i-fiber yeglasi zifanelekile ukuhlamba kwi-nitrogen medium.
