Nɛgɛ-PTFE sinsinni .
Se: Baarakɛminɛn funteni hakɛ : -100℃~ -250℃.
Baarakɛ tansiyɔn cɛmancɛ .: Tansiyɔn ɲuman: 2,5MPa, tansiyɔn jiginni 70 kPa so funteni na .
Corrosion resistance .: Politetarafoɛtilɛni fɛnɲɛnamafagalan, ka fara nɛgɛ litiyɔmu wulilen kan, potasiyɔmu, soja, kulori trifluoride, oksizɛni trifluoride funteni caman na, fluor jilama hakɛ caman, a bɛ se ka kɛ sababu ye ka asidi azotiki caman ni ji nɔgɔlenw bɛɛ kunbɛn, a bɛ se ka baara kɛ ni waati jan ye degere 230 na. Fluoride polyvinylidene walima vinilidene fluoride tuubu wɛrɛw bɛ se ka halojeni, halojenihidrokarbon, oksidan barikama, asidi tobilen, alkali, fɛnɲɛnamafagalanw suguya caman, nka asidi sulfuriki sisilen, asidi suma ni asidi nitiriti, fɛnɲɛnamafagalan minnu bɛ kɛ ni 90 ye, olu tɛ se ka kunbɛn.
Aplikasi typique .U bɛnnen don gaziw ni jilama barikamaw ma funteni caman na, nɛgɛ suguya wɛrɛw{0}}Plastic composite pipes ani metal pipes ye fɛn ye min tɛ se ka lase, nɛgɛ politefe composite tubes bɛnnen don, nɛgɛ polimetluorinated composite pipes bɛnnen don ka baara funteni hakɛ 40 degre
Fɛn dilanni taabolo .: Aw bɛ fɔlɔ ka PTFE mugu caman kɛ, aw bɛ (squeeze) don pipe kɔnɔ, ka sɔrɔ k’a waajibiya ka don nɛgɛ pipe la min tɛ fɛn tiɲɛ (pipe min bɛ kɛ ni finimugu ye, o kɛnɛma janya ka bon dɔɔni ka tɛmɛ nɛgɛ pipe kɔnɔna cɛmancɛ kan 1,5-2mm), walasa ka a siri ni yɔrɔ ye min tɛ ni yɔrɔ ye. Walasa ka degun ban, aw bɛ a bila funteni na foro kɔnɔ ani ka a sumaya fo ka se 180 oc ma fo ka se funteni hakɛ ma min bɛ degere 180 duguma . O waati kelen na, axial tensile strength of the push (squeeze) pressure pipe ka fisa kosɛbɛ ni winding pipe ye. Nin pibiliki in bɛ ni tansiyɔn jiginni seko ɲuman ni juguman ye.
