PTFE (polytetrafluoroethylene) ucingoyintambo ekhethekileyo yokusebenza okuphezulu kunye noluhlu olubanzi lwezicelo kunye neempawu zokusebenza ezizodwa.
Ⅰ. Isicelo
1.Imimandla ye-elektroniki kunye nombane
● Unxibelelwano lwe-High-frequency: Kwizixhobo zonxibelelwano ze-high-frequency ezifana ne-5G yonxibelelwano kunye ne-radar, ucingo lwe-PTFE lunokusetyenziswa njengomgca wokuhambisa. Inokugcina ilahleko yesignali ephantsi ngexesha lokudluliselwa kwesignali ye-high-frequency kunye nokuqinisekisa ukunyaniseka komqondiso kunye nokuzinza. Umzekelo, kuqhagamshelo phakathi kwe-eriyali yesiseko sesikhululo kunye nesixhobo sokuhambisa, ucingo lwe-PTFE lunokuhambisa ngokufanelekileyo imiqondiso ye-electromagnetic wave ukuze kuqinisekiswe unxibelelwano olukhawulezayo noluthembekileyo.
● Iintambo zangaphakathi zesixhobo sombane: ezisetyenziselwa iintambo zombane kunye neentambo zesignali ngaphakathi kwesixhobo sombane ezifana neekhompyutha neeseva. Ngenxa yokusebenza kwayo kakuhle kwe-insulation kunye nokumelana nokushisa okuphezulu, kunokuthintela umonakalo ngaphakathi kwezixhobo ze-elektroniki ngenxa yesiphaluka esifutshane okanye ukufudumala. Ngokomzekelo, ngaphakathi kwekhadi lemizobo ephezulu, ucingo lwe-PTFE lunokumelana nobushushu obuphezulu obuveliswa yikhadi lemifanekiso xa lisebenza, ngelixa liqinisekisa ukuchaneka kokuhanjiswa komqondiso.
2.Ibala le-Aerospace
● Ukufakwa kweentambo kwinqwelo-moya: ukufakela iintambo kwiindawo eziphambili ezifana nenkqubo yokubhabha kwenqwelo-moya kunye nenkqubo yokulawula ukubhabha. Ukumelana nobushushu obuphezulu, ukuxhathisa kwe-corrosion kunye nokumelana nemitha ye-PTFE yocingo kwenza ukuba ikwazi ukuziqhelanisa neemeko ezinzima zokusingqongileyo ngexesha lokuhamba kwenqwelomoya. Ngokomzekelo, kwi-injini ye-injini yendiza, apho ubushushu be-ambient buphezulu kwaye kukho izinto ezinobungozi ezifana ne-fuel, ucingo lwe-PTFE lunokuqinisekisa ukuhanjiswa okuqhelekileyo kweempawu zokulawula injini kunye neempawu zenzwa.
● Iingcingo zesiphekepheke: ezisetyenziselwa iintambo zeenkqubo zombane zeziphekepheke ezifana neesathelayithi neziphekepheke. Iyakwazi ukumelana nokutshintsha kobushushu obugqithisileyo esithubeni (ukusuka kwiqondo lobushushu eliphantsi kakhulu ukuya kwiqondo eliphezulu) kunye nemimandla ephezulu yokusasazeka kwemitha. Kwinkqubo yonxibelelwano yesathelayithi kunye nenkqubo yokulawula isimo sengqondo, ucingo lwe-PTFE luqinisekisa ukuhanjiswa okuzinzile kweempawu kwindawo enzima yendawo.
3.Indawo yeemoto
● Iintambo zombane ezinombane ophezulu kwizithuthi zamandla amatsha: Kwizithuthi zamandla amatsha, ucingo lwe-PTFE lusetyenziselwa ukudibanisa izinto ezifana neepakethi zebhetri, iimotha, kunye neeyunithi zolawulo lombane ophezulu. Ine-insulation efanelekileyo kunye nokumelana nobushushu obuphezulu, kwaye inokumelana nombane ophezulu kunye nephezulu yangoku eyenziwa xa izithuthi zamandla amatsha zisebenza. Ngokomzekelo, ngaphakathi kwebhetri ye-high-voltage pack yemoto yombane, ucingo lwe-PTFE lunokuthintela iisekethe ezimfutshane ngaphakathi kwipakethi yebhetri, ukuqinisekisa ukuba ibhetri ngokukhuselekileyo nangokuzinzileyo inika amandla kwisithuthi.
● Isixhobo sokwenza iintambo zesivamvo se-Automotive: isetyenziselwa ukudityaniswa kwee-automotive sensors ezahlukeneyo (ezifana ne-injini yoluvo, i-body sensors, njl.njl.). Ukuxhathisa kwe-oyile kunye nokumelana nokubola kwe-PTFE ucingo kwenza ukuba ikwazi ukuziqhelanisa neendawo ezinzima ezifana ne-injini ye-injini yemoto, iqinisekisa ukuhanjiswa ngokuchanekileyo kweempawu zenzwa.
I-4.Industrial Automation Field
● Iingcingo zeRobhothi: Iingcingo phakathi kwekhabhinethi yolawulo kunye nengalo yerobhothi yerobhothi yoshishino. Ucingo lwe-PTFE lunokuguquguquka okuhle kwaye luyakwazi ukuziqhelanisa nentshukumo rhoqo kunye nokugoba kwengalo yerobhothi yerobhothi. Ngelo xesha, ukuxhathisa kwayo kweekhemikhali kunokuthintela ukubola kweekhemikhali ezahlukeneyo kwindawo yoshishino kumgca, ukuqinisekisa ukuhanjiswa okuzinzile kwesignali yokulawula irobhothi.
● I-Industrial Automation Equipment Wiring: Isetyenziselwa ukudibanisa izixhobo ezahlukeneyo (njengabalawuli be-PLC, i-inverters, njl.) kumgca wokuvelisa ngokuzenzekelayo. Iyakwazi ukumelana nommandla onzima wokushisa okuphezulu, uthuli kunye nezinye iindawo ezinzima kwindawo yoshishino, ukuqinisekisa ukuthembeka kokuhanjiswa komqondiso kunye nokunikezelwa kwamandla phakathi kwezixhobo ezizenzekelayo.
Ⅱ. Iimbonakalo
1.Ukusebenza koMbane
● High Insulation Resistance: I-insulation resistance yocingo lwe-PTFE iphezulu kakhulu, idla ngokufikelela kulandelelwano lwe-10¹⁰ - 10¹⁴Ω·m. Oku kuthetha ukuba phantsi kweemeko eziqhelekileyo zokusebenza, kunokuthintela ngokufanelekileyo ukuvuza kwangoku kunye nokuqinisekisa ukusebenza okuqhelekileyo kwesekethe. Ngokomzekelo, kwizixhobo ezichanekileyo zokulinganisa i-elektroniki, ucingo lwe-PTFE lunokuqinisekisa ukuba isignali yokulinganisa ayiphazamiseki kwihlabathi langaphandle kwaye iphucule ukuchaneka komlinganiselo.
● I-Dielectric Constant ephantsi kunye ne-Dielectric Loss: I-dielectric constant iphantsi (malunga ne-2.1) kunye nokulahlekelwa kwayo kwe-dielectric kuncinci. Oku kwenza ucingo lwe-PTFE luncitshiswe kakhulu xa uhambisa imiqondiso ye-frequency ephezulu, kwaye inokugcina ingqibelelo yomqondiso. Kwiinkqubo ze-high-speed data transmission systems, ezifana ne-jumpers edibanisa iintambo ze-optical kunye nezixhobo zombane kwi-fiber-optic communications, iingcingo ze-PTFE zinokuqinisekisa ukuba iimpawu zedatha zithunyelwa ngokukhawuleza nangokuchanekileyo.
2.Iimpawu zomzimba
● Ukumelana nobushushu obuphezulu: ucingo lwe-PTFE lunokugcina ukusebenza kakuhle kuluhlu olubanzi lobushushu (-200℃ - 260℃). Kwiindawo zobushushu obuphezulu, ayizukuthamba, ikhubazeke okanye itshise njengeingcingo zeplastiki eziqhelekileyo. Ngokomzekelo, kwi-wiring ye-sensor sensors kwezinye ii-furnaces ze-industry-high-temperature, i-PTFE ucingo inokuqinisekisa ukuhanjiswa okuzinzile kwezibonakaliso zenzwa kwiindawo eziphezulu zokushisa.
● Ukumelana nokutyiwa kweekhemikhali: Inokumelana ne-corrosion eyomeleleyo kwiikhemikhali ezininzi (ezifana ne-acids ezomeleleyo, ii-alkali ezinamandla, izinyibilikisi eziphilayo, njl. njl.). Oku kuvumela ucingo lwe-PTFE ukuba lusetyenziswe kwiindawo ezinobume ezonakalisayo ezifana neshishini lemichiza kunye neshishini loxubo-mayeza. Ngokomzekelo, kwi-wiring yeqondo lokushisa kunye ne-pressure sensors ngaphakathi kwe-reactor yefektri yamayeza, ucingo lwe-PTFE lunokumelana nokukhukuliseka kweekhemikhali ezahlukeneyo.
3.Iimpawu zeMechanical
● Ukuba bhetyebhetye okulungileyo: ucingo lwe-PTFE lunokuguquguquka okuhle kwaye lunokugotywa lula kwaye lufakwe. Kwezinye iimeko apho isithuba sinqongophele okanye intshukumo rhoqo iyafuneka (njengokungenwa kwangaphakathi kweerobhothi), oku kuguquguquka kuyenza ikwazi ukuziqhelanisa neemfuno zocingo ezintsonkothileyo. Ngelo xesha, ayiyi kuphuka okanye iyancipha ekusebenzeni ngexesha lokugoba.
● Amandla okuzibamba aphakathi: Inamandla athile okuzibamba kwaye inokumelana nomlinganiselo othile woxinzelelo. Ngethuba lenkqubo ye-wiring, nangona ikhutshwe kwinqanaba elithile, ayiyi kuphuka lula, iqinisekisa ukunyaniseka komgca.
