Kukho iindidi ezimbini zetyhubhu ye-PTFE: ityhubhu ephumayo kunye netyhubhu ebunjiweyo.Kwiiplastiki ezaziwayo, i-PTFE inokumelana neekhemikhali ezilungileyo kunye nemisebenzi ye-dielectric, kwaye ingasetyenziselwa kumaqondo obushushu e--180 ° C ukuya ku-+260 ° C, kunye ne-coefficient ephantsi kakhulu yokukhuhlana, ifaneleka kakhulu kwiimveliso ezide kunye nezingekho. -Iinxalenye zomatshini eziqhelekileyo: izitywina / i-washers, imisesane, iipleyiti zokugqoka / izihlalo, iindawo zokugquma, imisebenzi yokumelana ne-corrosion, i-mechanical parts, i-linings, i-Oli kunye negesi, imboni ye-petrochemical, imboni yeekhemikhali, isixhobo kunye nomvelisi wezixhobo, njl.

Umsebenzi we-Anti-yangoku we-PTFE ityhubhu
Kwisicelo, ityhubhu ye-PTFE kufuneka ibe bhetyebhetye kakhulu, ngaphandle kokuqhekeka / ukufakwa okuya kuchaphazela umsebenzi wokufakelwa.
Ukongezelela, ekubeni imfuno ingaba yintambo enokuthi idibaniswe ngaphandle kokudibanisa, ityhubhu ye-PTFE ngokwayo kufuneka ibe ubude obuqhubekayo.Ngoko ke, kuyimfuneko ukukwazi ukuvelisa imibhobho yokudibanisa kunye nobude ubuncinane be-150 ukuya kwi-300 yeemitha ngaphandle kokungalungi.
Ityhubhu ye-PTFE inomsebenzi ophezulu kakhulu wokuchasa okwangoku.Akukho ndlela yokuba umbane ongatshintshiyo ubambelele kumphezulu wezinto nge-PTFE.Nje ukuba kufikelelwe kwinqanaba elibalulekileyo, kunokwenzeka ukuba kubekho iintlantsi.
Kwizicelo ezichukumisa umphunga ovuthayo, iintlantsi ziyingozi kakhulu.Ukuze kulungiswe le ngxaki, i-filler efana nekhabhoni yongezwa kwi-tube ye-PTFE ukukhupha umbane ongatshintshiyo ngokusebenzisa idatha.Ukongezwa kwekhabhoni kunciphisa umsebenzi wokugquma we-PTFE ityhubhu ukuya kwinqanaba elithile, kodwa umsebenzi wezinto eziphathekayo usephezulu kakhulu kunawo nawuphi na umbhobho oqhelekileyo.
Iimpawu eziphambili ze-PTFE ityhubhu
1. ityhubhu ye-PTFE ingasetyenziswa njenge-insulator yocingo, umbhobho wezixhobo zonyango, umbhobho wokuhamba kwamanzi, i-sheath, njl.
2. Umgangatho obalaseleyo we-thermal, unokwamkela amaqondo obushushu ukuya kuma-680 degrees Fahrenheit, kunye neemeko zeqondo lokushisa eliphantsi lehla ukuya kuma-320 degrees Fahrenheit.
3.Ineempawu ezibalaseleyo zombane kunye ne-dielectric ephantsi ye-2.1 phakathi kwe--40 degrees Fahrenheit kunye ne-480 degrees Fahrenheit.
4. Ine-coefficient ye-static friction.
5. Yiba livila ngamachiza kunye neekhemikhali ezininzi ze-organic kunye ne-inorganic.
