Muddada dammaanadda waa sifo aasaasi ah oo ay tahay in badeecad kastaa lahaato.Muddada dammaanadda waa wakhtiga hubinta tayada.Waa nooc ka mid ah hubinta tayada alaabta muddo cayiman gudaheed.Isla sidaas oo kale ayaa run u ah alaabta PTFE.In kasta oo aan wada ognahay in alaabooyinka PTFE ay leeyihiin nolol adeeg dheer, intee in le'eg ayay tahay nolosha adeeggu?Dad badan ayaa laga yaabaa inaysan wax badan ka ogeyn.Haddaba, aan tusaale u soo qaadanno guddiga PTFE si aan kula wadaagno Soo bandhig nolosha adeegga alaabta PTFE.
Nolosha adeegga eexaashida PTFEwaa mid aad u dheer, sababtoo ah xaashida PTFE waa sheyga PTFE ee saxan ah oo lagu farsameeyo hannaan gaar ah (ama dhimo goynta ama leexashada) ee walxaha PTFE, iyo walxaha PTFE laftiisa Waa walxo leh sifooyin waxqabad oo aad u fiican, oo ay ku jiraaniska caabinta heerkulka sare, kaas oo loo isticmaali karo heerkul ah 200 ~ 260 digrii muddo dheer;iska caabinta heerkulka hooseeya, xitaa -100 digrii, walxaha PTFE weli waa jilicsan;iska caabinta daxalka, waxay u adkeysan kartaa aqua regia Iyo dhammaan dareerayaasha organic;iska caabinta cimilada, soo-gaadhista muddada-dheer ee jawiga, dusha sare iyo wax-qabadku isma beddelaan, caabbinta shucaaca iyo qulqulka hooseeya ayaa sidoo kale ka sii fiican;sifaynta sare, oo leh iskudhaf yar oo jajab ah oo balaastik ah, Isku-dubarid isku-dhafan waa kaliya 0.04;waxay leedahay xiisad yar oo dusha sare ah oo ku jirta maaddooyinka adag mana u hoggaansamaan walxo kasta;waa physiologically aan firfircoonayn oo aan sun ahayn;Guryaha korantada ee aad u fiican, waa wax ku habboon Class C insulating, iyo lakab qaro weyn oo wargeys ah ayaa xannibi kara tamarta sare ee 1500V;... Sidaa darteed, tayada xaashida PTFE ee ka samaysan walxaha PTFE waa mid aad u deggan xaaladaha caadiga ah waa tayada ugu xasiloon xaashida PTFE ee ku taxan buugaagta badankooda ama internetka.Ma diidno sifooyinka, laakiin weli waa inaan sharaxnaa sifooyinka kale eexaashida PTFEtaas oo u baahan in la sharaxo.
Badeeco kasta ayaa balaarin doonta oo qandaraas kulaylkarta, halka xaashida PTFE ay aad ugu nugul tahay ballaarinta kulaylka iyo foosha, iyo isugeynta ballaarinta xaashida PTFE waxay ku dhowdahay toban jeer ka birta.Sidaa darteed, marka xaashida PTFE lagu sameeyo isbeddel heerkuleed, waxay saameyn weyn ku yeelan doontaa cabbirka xaashida PTFE, sida gu'ga, xagaaga, dayrta iyo jiilaalka.Meelo badan oo dalkeena ka mid ah, farqiga heerkulka u dhexeeya afarta xilli waa mid aad u weyn.Isbeddelka heerkulka gu'ga, xagaaga, dayrta iyo jiilaalka, guddiga ayaa sidoo kale sii weynaanaya ama yareynaya, xaaladdan ayaa jirta.Waxaa xusid mudan in inkasta oo xaashida PTFE ay wax yar beddeli doonto saamaynta kulaylka iyo qabowga, haddana tayada gudaha ma beddeli doonto.isbedeli doona.
Xaashida cusub ee PTFE heerka QB/T5257-2018 waxay si cad u qeexaysaa in muddada dammaanadda ee xaashida PTFE ay tahay toban sano.Tani waa markii ugu horeysay ee muddada dammaanadda ee alaabta PTFE lagu daro baaxadda heerarka warshadaha qaranka.
