Ƙananan juzu'i da mafi ƙarancin amfani da wutar lantarki sune fa'idodin fa'idodin da hatimin PTFE ke bayarwa.Ana iya amfani da waɗannan hatimin ba tare da matsaloli ba tare da bushewa…
Duk da kyawawan kaddarorin sa tsarkakakku, marasa cika ko budurwa PTFE bai isa ba don ƙarin aikace-aikacen injiniya masu buƙata.Musamman, yanayin sanyin sa ko halayen rarrafe ya hana amfani da PTFE a aikace-aikacen injina.Ko da a dakin da zafin jiki, PTFE fuskanci wani gagarumin nakasawa a kan lokaci a lokacin da shi ne hõre wani m load. Har ila yau, budurwa PTFE yana da wuya wani resilience da sawa da sauri duk da low coefficient na friction.In 1960 ta, Bugu da kari na fillers aka samu zuwa inganta yawan kaddarorin jiki, musamman masu rarrafe da yawan lalacewa.Yawancin masu cikawa sun tsaya tsayin daka har zuwa 400 ° C, don haka ba sa hana amfani a cikin yanayin zafi mai girma. An jera su a ƙasa wasu abubuwan filler na yau da kullun da tasirin su akan kaddarorin jiki na fili na PTFE.
Gilashin fiber
Gilashin fiber wani nau'in filler ne da aka saba amfani dashi tare da ingantacciyar tasiri akan aikin PTFE mai raɗaɗi, wanda aka rage a ƙasa da yanayin zafi.Hakanan yana ƙara juriya na lalacewa kuma yana ba da ƙarfin matsawa mai kyau.Wannan ƙari ba shi da ƙarancin sinadarai sai dai a gaban hydrofluoric acid da tushe mai ƙarfi.Yana da ɗan tasiri akan abubuwan lantarki.
Carbon da carbon-graphite
Carbon yana rage raƙuman ruwa, yana ƙara taurin kai kuma yana haɓaka haɓakar thermal na PTFE.Juriya na abubuwan da ke cike da carbon yana inganta musamman a hade tare da graphite.Carbon yana ɗaya daga cikin mafi ƙarancin cikawa sai dai a cikin mahalli mai oxidizing inda gilashin ya fi kyau.PTFE cike da carbon ne yawanci amfani da pneumatic sealing applications.Compounds tare da carbon a hade tare da graphite ne fĩfĩta kayan don wadanda ba lubricated aikace-aikace.
Carbon fiber
Bugu da ƙari na carbon fiber zuwa PTFE yana canza kaddarorinsa kamar yadda fiber gilashin ke yi.Yana saukar da rarrafe, yana ƙara sassauƙa da matsawa kuma yana ɗaga tauri.Gabaɗaya, ana buƙatar ƙarancin fiber na carbon fiye da fiber na gilashi don cimma sakamako iri ɗaya. An saukar da ƙimar haɓakar haɓakar thermal kuma haɓakar thermal yana da girma don mahadi na fiber carbon cike PTFE.Yawan sawa yana raguwa lokacin da sassan fiber carbon ke shafa su da ruwa. Fiber carbon ba shi da sinadarai kuma ana iya amfani dashi a cikin tushe mai ƙarfi da acid hydrofluoric.
Graphite
Graphite shine gyare-gyaren kristal na carbon mai tsabta.Graphite cike da PTFE yana da ɗayan mafi ƙanƙanta ƙididdiga na gogayya saboda ƙarancin halayen graphite.Yana da kyawawan kaddarorin lalacewa, musamman a kan filaye masu laushi kuma yana nuna babban ƙarfin ɗaukar kaya a aikace-aikacen tuntuɓar mai sauri.Graphite ba shi da sinadari wanda ke ba da damar amfani da shi a cikin kafofin watsa labarai masu lalata.
Tagulla
Bronze filler ne na gama gari.Babban adadi (40 zuwa 60% ta nauyi) tagulla yana rage nakasawa a ƙarƙashin kaya kuma yana haɓaka haɓakar thermal da lantarki na mahadi na PTFE.Wadannan halaye guda biyu suna da amfani ga aikace-aikace inda aka sanya wani sashi a cikin matsanancin yanayin zafi.Bronze cike da PTFE yana ba da kyawawan halayen juriya na extrusion.Tagulla wani abu ne na jan karfe da kwano kuma wasu sinadarai na iya kaiwa hari.Oxidation na tagulla na iya haifar da canza launi na ɓangaren da aka gama ba tare da tasiri akan ingancin samfurin ba.PTFE da aka cika da tagulla ana amfani dashi sosai a cikin sandar hydraulic da aikace-aikacen hatimin piston.
Molybdenum disulfide (MoS2)
Molybdenum disulphide yana ƙara tauri da taurin PTFE yayin rage juzu'i.Yana da ɗan tasiri akan kaddarorin sa na lantarki.Chemically, ba ya aiki da yawa kuma yana narkar da shi kawai a cikin acid mai ƙarfi mai ƙarfi.Ana amfani da shi a cikin ƙananan nau'i mai nauyi kuma a hade tare da sauran filaye kamar fiber gilashi.
Polyester mai ƙanshi
Aromatik polyester a matsayin mai filler yana ɗaga babban juriya na zafin jiki na PTFE kuma yana da kyau don amfani tare da laushi, tsauri mai ƙarfi.
Additives launi
Yana yiwuwa a yi launin PTFE ta amfani da abubuwan da ba a iya amfani da su na launi ba waɗanda ke jure yanayin zafin jiki na PTFE.Pigments ba su canza kaddarorin PTFE ba.Haɗe-haɗe na pigments da sauran masu cikawa suna yiwuwa.Masu sarrafa kayan da aka mallaka da haɗin kaiParker yana ci gaba da ƙoƙari don nema da haɓaka abubuwan haɗin gwiwa na musamman da ƙirar ƙira don haɓaka aikin rufewa a cikin mafi girman aikace-aikacen.
