Intambo ye-PTFE (polytetrafluoroethylene)iyikhebula elikhethekile elisebenza kahle kakhulu elinezinhlelo zokusebenza eziningi kanye nezici zokusebenza ezihlukile.
Ⅰ. Isicelo
1. Amasimu kagesi kanye nogesi
● Ukuxhumana okuvamise kakhulu: Emishinini yokuxhumana okuvamise kakhulu njengokuxhumana kwe-5G kanye ne-radar, ucingo lwe-PTFE lungasetshenziswa njengomugqa wokudlulisela. Lungagcina ukulahleka kwesignali okuphansi ngesikhathi sokudluliselwa kwesignali okuvamise kakhulu futhi luqinisekise ubuqotho besignali kanye nokuzinza. Isibonelo, ekuxhumaneni phakathi kwe-antenna yesiteshi esiyisisekelo kanye nemishini yokudlulisa, ucingo lwe-PTFE lungadlulisela ngempumelelo izimpawu zamagagasi kagesi avame kakhulu ukuqinisekisa ukuxhumana okushesha kakhulu nokuthembekile.
● Izintambo zangaphakathi zemishini kagesi: ezisetshenziselwa izintambo zikagesi nezintambo zesignali ngaphakathi kwemishini kagesi efana namakhompyutha namaseva. Ngenxa yokusebenza kwayo okuhle kokushisa kanye nokumelana nokushisa okuphezulu, ingavimbela umonakalo ngaphakathi kwemishini kagesi ngenxa ye-short circuit noma ukushisa ngokweqile. Isibonelo, ngaphakathi kwekhadi lezithombe elisebenza kahle kakhulu, intambo ye-PTFE ingamelana nokushisa okuphezulu okukhiqizwa yikhadi lezithombe lapho isebenza, ngenkathi iqinisekisa ukunemba kokudluliswa kwesignali.
2. Insimu ye-Aerospace
● Ukufakwa kwezintambo endizeni: ukufakwa kwezintambo ezingxenyeni ezibalulekile njengohlelo lwezindiza zendiza kanye nohlelo lokulawula izindiza. Ukumelana nokushisa okuphezulu, ukumelana nokugqwala kanye nokumelana nemisebe yocingo lwe-PTFE kwenza ikwazi ukuzivumelanisa nezimo zemvelo eziyinkimbinkimbi ngesikhathi sokundiza kwendiza. Isibonelo, endaweni yenjini yendiza, lapho izinga lokushisa elizungezile liphezulu futhi kunezinto ezigqwalisayo njengophethiloli, ucingo lwe-PTFE lungaqinisekisa ukudluliswa okuvamile kwezimpawu zokulawula injini kanye nezimpawu zezinzwa.
● Izintambo zomkhumbi-mkhathi: ezisetshenziselwa ukuxhuma izinhlelo ze-elekthronikhi zemikhumbi-mkhathi njengeziphuphutheki kanye nemikhumbi-mkhathi. Ingamelana nokushintsha okukhulu kokushisa esikhaleni (kusukela ekushiseni okuphansi kakhulu kuya ekushiseni okuphezulu) kanye nezindawo ezinemisebe ephezulu. Ohlelweni lokuxhumana lwesathelayithi kanye nohlelo lokulawula isimo sengqondo, intambo ye-PTFE iqinisekisa ukudluliswa okuzinzile kwezimpawu endaweni enzima yesikhala.
3. Inkambu yezimoto
● Intambo ye-high-voltage yezimoto ezintsha zamandla: Ezimotweni ezintsha zamandla, intambo ye-PTFE isetshenziselwa ukuxhuma izingxenye ezifana namaphakethe ebhethri, ama-motor, kanye namayunithi okulawula ama-high-voltage. Inokushisa okuhle kanye nokumelana nokushisa okuphezulu, futhi ingamelana ne-voltage ephezulu kanye nogesi ophezulu okhiqizwayo lapho izimoto ezintsha zamandla zisebenza. Isibonelo, ngaphakathi kwephakethe lebhethri le-high-voltage yemoto kagesi, intambo ye-PTFE ingavimbela ama-short circuits ngaphakathi kwephakethe lebhethri, iqinisekise ukuthi ibhethri linikeza amandla emotweni ngokuphepha nangokuzinzile.
● Intambo yenzwa yezimoto: esetshenziselwa ukuxhumanisa izinzwa zezimoto ezahlukahlukene (njengezinzwa zenjini, izinzwa zomzimba, njll.). Ukumelana nowoyela kanye nokumelana nokugqwala kwentambo ye-PTFE kuyenza ikwazi ukuzivumelanisa nezimo eziyinkimbinkimbi njengegumbi lenjini yemoto, okuqinisekisa ukudluliswa okunembile kwezimpawu zezinzwa.
4. Insimu Yokuzenzakalela Kwezimboni
● Ukuxhumanisa Amarobhothi: Ukuxhumanisa amarobhothi phakathi kwekhabhinethi yokulawula kanye nengalo yerobhothi yezimboni. Intambo ye-PTFE inokuguquguquka okuhle futhi ingazivumelanisa nokunyakaza okuvamile kanye nokugoba kwengalo yerobhothi yezimboni. Ngesikhathi esifanayo, ukumelana kwayo nokugqwala kwamakhemikhali kungavimbela ukugqwala kwamakhemikhali ahlukahlukene endaweni yezimboni emugqeni, okuqinisekisa ukudluliswa okuzinzile kwesiginali yokulawula irobhothi.
● Izintambo Zemishini Yokuzenzakalela Yezimboni: Isetshenziselwa ukuxhuma imishini ehlukahlukene (njengezilawuli ze-PLC, ama-inverter, njll.) emgqeni wokukhiqiza ozenzakalelayo. Ingamelana nesimo sezulu esinzima sokushisa okuphezulu, uthuli nezinye izindawo ezinzima endaweni yezimboni, iqinisekisa ukuthembeka kokudluliselwa kwesignali kanye nokunikezwa kwamandla phakathi kwemishini ezenzakalelayo.
Izici ze-Ⅱ
1. Ukusebenza kukagesi
● Ukumelana Okuphezulu Kokushisa: Ukumelana kokushisa kwentambo ye-PTFE kuphakeme kakhulu, ngokuvamile kufinyelela ku-oda lika-10¹⁰ - 10¹⁴Ω·m. Lokhu kusho ukuthi ngaphansi kwezimo zokusebenza ezijwayelekile, kungavimbela ngempumelelo ukuvuza kwamandla kagesi futhi kuqinisekise ukusebenza okuvamile kwesekethe. Isibonelo, kumathuluzi okulinganisa kagesi anembe kakhulu, intambo ye-PTFE ingaqinisekisa ukuthi isignali yokulinganisa ayiphazanyiswa yizwe langaphandle futhi ithuthukise ukunemba kokulinganisa.
● Ukulahlekelwa Okuphansi Kwe-Dielectric Okuhlala Njalo kanye Ne-Dielectric: I-dielectric constant yayo iphansi (cishe ngo-2.1) futhi ukulahleka kwayo kwe-dielectric nakho kuncane. Lokhu kwenza intambo ye-PTFE inganciphisi kakhulu lapho ithumela amasignali aphezulu, futhi ingagcina ubuqotho besignali. Ezinhlelweni zokudlulisa idatha ngesivinini esikhulu, njengezithupha ezixhumanisa izintambo ze-optical namadivayisi kagesi ekuxhumaneni kwe-fiber-optic, izintambo ze-PTFE zingaqinisekisa ukuthi amasignali edatha adluliselwa ngokushesha nangokunembile.
2. Izakhiwo zomzimba
● Ukumelana nokushisa okuphezulu: Intambo ye-PTFE ingagcina ukusebenza okuhle ebangeni elibanzi lokushisa (-200℃ - 260℃). Ezindaweni ezishisa kakhulu, ngeke ithambise, ishintshe noma ishise njengezintambo zepulasitiki ezivamile. Isibonelo, ekuxhunyweni kwezinzwa zokushisa kwezinye izitofu zezimboni ezishisa kakhulu, intambo ye-PTFE ingaqinisekisa ukudluliswa okuzinzile kwezimpawu zezinzwa ezindaweni ezishisa kakhulu.
● Ukumelana nokugqwala kwamakhemikhali: Inokumelana okunamandla nokugqwala kwamakhemikhali amaningi (njenge-asidi enamandla, ama-alkali aqinile, izinyibilikisi eziphilayo, njll.). Lokhu kuvumela ucingo lwe-PTFE ukuthi lusetshenziswe ezindaweni ezinezindawo ezigqwalisayo njengemboni yamakhemikhali kanye nemboni yemithi. Isibonelo, ekuxhunyweni kwezinzwa zokushisa kanye nokucindezela ngaphakathi kwe-reactor yefektri yemithi, ucingo lwe-PTFE lungamelana nokugqwala kwamakhemikhali ahlukahlukene.
3. Izakhiwo zemishini
● Ukuguquguquka okuhle: Intambo ye-PTFE inokuguquguquka okuhle futhi ingagotshwa futhi ifakwe kalula. Kwezinye izimo lapho isikhala silinganiselwe noma kudingeka ukunyakaza okuvamile (njengokuxhuma kwangaphakathi kwamarobhothi), lokhu kuguquguquka kuyenza ikwazi ukuzivumelanisa nezidingo zokuxhuma eziyinkimbinkimbi. Ngesikhathi esifanayo, ngeke iphuke noma yonakale ekusebenzeni kwayo ngesikhathi sokugoba.
● Amandla okudonswa aphakathi nendawo: Inamandla okudonswa futhi ingamelana nokucindezeleka okuthile. Ngesikhathi senqubo yokuxhuma, noma ngabe idonswa ngezinga elithile, ngeke iphuke kalula, okuqinisekisa ubuqotho bomugqa.
