Intambo ye-PTFE (polytetrafluoroethylene).iyikhebula elikhethekile elisebenza kahle kakhulu elinezinhlobonhlobo zezinhlelo zokusebenza nezici zokusebenza eziyingqayizivele.
Ⅰ. Isicelo
1.Izinkundla zikagesi nezikagesi
● Ukuxhumana kwe-High-frequency: Ezisetshenziswa zokuxhumana ze-high-frequency ezifana nokuxhumana kwe-5G ne-radar, intambo ye-PTFE ingasetshenziswa njengolayini wokudlulisela. Ingakwazi ukugcina ukulahlekelwa kwesignali ephansi ngesikhathi sokudluliswa kwesignali ye-high-frequency futhi iqinisekise ubuqotho besignali nokuzinza. Isibonelo, ekuxhumaneni phakathi kwe-antenna yesiteshi sesisekelo nezinto zokudlulisa, intambo ye-PTFE ingadlulisela ngempumelelo amaza amaza kagesi we-high-frequency electromagnetic wave ukuze kuqinisekiswe ukuxhumana okunesivinini esikhulu nokuthembekile.
● Izintambo zangaphakathi zezinto zikagesi: ezisetshenziselwa izintambo zikagesi nezintambo zesignali ngaphakathi kwezinto zikagesi ezifana namakhompyutha namaseva. Ngenxa yokusebenza kwayo okuhle kwe-insulation kanye nokumelana nokushisa okuphezulu, kungavimbela ukulimala ngaphakathi kwemishini kagesi ngenxa yesifunda esifushane noma ukushisa ngokweqile. Isibonelo, ngaphakathi kwekhadi lezithombe ezisebenza kahle kakhulu, intambo ye-PTFE ingamelana nokushisa okuphezulu okukhiqizwa ikhadi lezithombe lapho isebenza, kuyilapho iqinisekisa ukunemba kokudluliswa kwesignali.
2.Inkundla ye-Aerospace
● Izintambo zendiza: izintambo ezingxenyeni ezibalulekile ezifana nesistimu yendiza yendiza kanye nesistimu yokulawula indiza. Ukumelana nokushisa okuphezulu, ukumelana nokugqwala kanye nokumelana nemisebe yocingo lwe-PTFE kuyenza ikwazi ukuzivumelanisa nezimo zemvelo eziyinkimbinkimbi phakathi nokundiza kwendiza. Isibonelo, engxenyeni yenjini yendiza, lapho izinga lokushisa lendawo liphezulu futhi kukhona izinto ezigqwalayo ezifana nophethiloli, intambo ye-PTFE ingaqinisekisa ukudluliswa okuvamile kwamasiginali okulawula injini namasignali enzwa.
● Izintambo zemikhumbi-mkhathi: ezisetshenziselwa izintambo zezinhlelo ze-elekthronikhi zemikhumbi-mkhathi njengamasathelayithi nemikhumbi-mkhathi. Ingakwazi ukumelana nokushintsha kwezinga lokushisa okwedlulele esikhaleni (kusuka kumazinga okushisa aphansi kakhulu ukuya kumazinga aphezulu okushisa) kanye nezindawo ezishisa kakhulu ngemisebe. Kuhlelo lokuxhumana lwesathelayithi kanye nohlelo lokulawula isimo sengqondo, intambo ye-PTFE iqinisekisa ukudluliswa okuzinzile kwamasignali endaweni enzima.
3.Inkundla yezimoto
● Intambo yezintambo ezinamandla amakhulu ezimotweni zamandla amasha: Ezimotweni zamandla amasha, intambo ye-PTFE isetshenziselwa ukuxhuma izingxenye ezifana namaphakethe ebhethri, amamotho, namayunithi okulawula amandla amakhulu. Ine-insulation enhle kanye nokumelana nezinga lokushisa eliphezulu, futhi ingakwazi ukumelana nogesi ophezulu kanye namandla aphezulu akhiqizwa lapho izimoto zamandla amasha zisebenza. Isibonelo, ngaphakathi kwephakethe lebhethri le-high-voltage yemoto kagesi, intambo ye-PTFE ingavimbela amasekhethi amafushane ngaphakathi kwephakethe lebhethri, iqinisekise ukuthi ibhethri linikeza amandla ngokuphephile nangokuzinzile emotweni.
● Amahhanisi ezintambo zenzwa yezimoto: asetshenziselwa ukuxhumeka kwezinzwa zezimoto ezihlukahlukene (njengezinzwa zenjini, izinzwa zomzimba, njll.). Ukumelana nowoyela nokumelana nokugqwala kwentambo ye-PTFE kuyenza ikwazi ukuzivumelanisa nezimo eziyinkimbinkimbi njengengxenye yenjini yemoto, iqinisekisa ukudluliswa okunembile kwamasignali wezinzwa.
4.Industrial Automation Field
● Izintambo zerobhothi: Izintambo phakathi kwekhabhinethi yokulawula kanye nengalo yerobhothi yerobhothi lezimboni. Intambo ye-PTFE inokuguquguquka okuhle futhi ingakwazi ukujwayela ukunyakaza nokugoba kwengalo yerobhothi yerobhothi. Ngesikhathi esifanayo, ukumelana nokugqwala kwamakhemikhali kungavimbela ukugqwala kwamakhemikhali ahlukahlukene endaweni yezimboni kulayini, kuqinisekiswe ukudluliswa okuzinzile kwesiginali yokulawula irobhothi.
● I-Industrial Automation Equipment Wiring: Isetshenziselwa ukuxhumeka kwemishini ehlukahlukene (njengabalawuli be-PLC, ama-inverters, njll.) emugqeni wokukhiqiza ozenzakalelayo. Ingakwazi ukumelana nemvelo enzima yokushisa okuphezulu, uthuli nezinye izimo ezinzima endaweni yezimboni, iqinisekisa ukwethembeka kokudluliswa kwesignali kanye nokunikezwa kwamandla phakathi kwemishini ezenzakalelayo.
Ⅱ. Izici
1.Ukusebenza kukagesi
● I-High Insulation Resistance: Ukumelana nokufakwa kwentambo ye-PTFE kuphezulu kakhulu, ngokuvamile kufinyelela ukuhleleka kuka-10¹⁰ - 10¹⁴Ω·m. Lokhu kusho ukuthi ngaphansi kwezimo ezijwayelekile zokusebenza, kungavimbela ngokuphumelelayo ukuvuza kwamanje futhi kuqinisekise ukusebenza okuvamile kwesifunda. Isibonelo, kumathuluzi okulinganisa ama-elekthronikhi anembayo ephezulu, intambo ye-PTFE ingaqinisekisa ukuthi isignali yokulinganisa ayiphazanyiswa umhlaba wangaphandle futhi ithuthukise ukunemba kwesilinganiso.
● I-Low Dielectric Constant kanye ne-Dielectric Loss: I-dielectric njalo iphansi (cishe i-2.1) futhi ukulahlekelwa kwayo kwe-dielectric nakho kuncane. Lokhu kwenza intambo ye-PTFE inganciphisi kangako lapho ithumela amasignali amafrikhwensi aphezulu, futhi ingagcina ubuqotho besignali. Ezinhlelweni zokudlulisa idatha ezihamba ngesivinini esiphezulu, njengama-jumpers axhuma izintambo zokubona kanye namadivayisi kagesi ekuxhumaneni kwe-fiber-optic, izintambo ze-PTFE zingaqinisekisa ukuthi amasignali edatha adluliselwa ngokushesha nangokunembile.
2.Izinto ezibonakalayo
● Ukumelana nezinga lokushisa eliphezulu: Intambo ye-PTFE ingagcina ukusebenza kahle ebangeni lokushisa elibanzi (-200℃ - 260℃). Ezimweni zokushisa okuphezulu, ngeke ithambe, ikhubaze noma ishise njengezintambo zepulasitiki ezijwayelekile. Isibonelo, ekufakweni kwezintambo kwezinzwa zokushisa kwamanye amaziko embonini anezinga lokushisa eliphezulu, intambo ye-PTFE ingaqinisekisa ukudluliswa okuzinzile kwamasignali enzwa ezindaweni zokushisa eziphezulu.
● Ukumelana nokugqwala kwamakhemikhali: Inokumelana nokugqwala okuqinile kumakhemikhali amaningi (njengama-asidi aqinile, ama-alkali aqinile, izinyibilikisi eziphilayo, njll.). Lokhu kuvumela intambo ye-PTFE ukuthi isetshenziswe ezindaweni ezinezimo ezonakalisayo ezifana nemboni yamakhemikhali kanye nemboni yezemithi. Isibonelo, ekufakweni kwezintambo kwezinzwa zokushisa nengcindezi ngaphakathi kwe-reactor yefekthri eyenza imithi, ucingo lwe-PTFE lungamelana nokuguguleka kwamakhemikhali ahlukahlukene.
3.Izakhiwo zemishini
● Ukuvumelana nezimo okuhle: Intambo ye-PTFE inokuguquguquka okuhle futhi ingagoba futhi ifakwe kalula. Kwezinye izikhathi lapho isikhala sinomkhawulo noma ukunyakaza okuvamile kuyadingeka (njengokufaka izintambo zangaphakathi zamarobhothi), lokhu kuvumelana nezimo kuyenza ikwazi ukuzivumelanisa nezimfuneko zezintambo eziyinkimbinkimbi. Ngesikhathi esifanayo, ngeke iphule noma yehlise ukusebenza ngesikhathi sokugoba.
● Amandla okuqina amaphakathi: Inamandla athile okuqina futhi ingamelana nenani elithile lokushuba. Phakathi nenqubo ye-wiring, ngisho noma idonswa ngezinga elithile, ngeke iphule kalula, iqinisekise ubuqotho bomugqa.
