PTFE Single Sphere Double Sphere Flexible Rubber Expension Joint With Flange

Zogulitsa Zambiri

PTFEmphira yowonjezera yowonjezerandi chinthu chamalipiro chomwe chimagwiritsidwa ntchito pamapaipi, omwe nthawi zambiri amakhala ndi zinthu zakunja za rabara komanso zokutira zamkati za PTFE. Ikhoza kuchepetsa kupsinjika ndi kuwonongeka kwa mapaipi potengera kugwedezeka, phokoso, ndi mafunde amphamvu, ndikukwaniritsa kudalirika ndi chitetezo cha mapaipi.

Kodi ubwino ndi kuipa kwa PTFE kukulitsa mphira olowa ndi chiyani?

Ubwino

1.Kukana kwabwino kwa dzimbiri: Polytetrafluoroethylene ndi zinthu zopanda mankhwala zomwe zimakhala ndi mphamvu zowonongeka ndipo zimatha kugwiritsidwa ntchito pazinthu zowonongeka monga ma acid, alkalis, ndi mchere.

2.Good kutentha kukana: PTFE angagwiritsidwe ntchito pa kutentha kwa 260 ℃, kotero PTFE mphira kutambasuka olowa ndi oyenera dongosolo payipi pansi pa kutentha chilengedwe.

3.Kukana kuvala bwino: pamwamba pa PTFE ndi yosalala kwambiri ndipo imakhala ndi kukana kwabwino, zomwe zimapangitsaPTFE Kukula kolumikizana kwa mphira kumakhala ndi ntchito yayitali

Zoipa

1. Mtengo wapamwamba:PTFE yolumikizira mphira yowonjezeraali ndi kukana kwa dzimbiri komanso kutentha kwambiri, motero mtengo wake wazinthu ndi wokwera kwambiri, zomwe zimapangitsa kuti mtengo wake ukhale wokwera.

2.Kuyika ndi kukonza ndizovuta: PTFE yowonjezera mphira yowonjezera iyenera kukhazikitsidwa molingana ndi zofunikira zowonongeka, ndipo kuyika kosayenera kudzakhudza ntchito yabwino ya payipi. Kuphatikiza apo, zida za PTFE ndizosalimba kuposa zida wamba za mphira, ndipo ngati kuwonongeka kumachitika pakagwiritsidwa ntchito, m'malo mwake ndikofunikira kuti mupewe kutayikira kwa payipi.

3.Stress kuchepetsa: Ngakhale PTFE mphira kutambasula olowa akhoza kuyamwa kugwedera, phokoso ndi kuthamanga mafunde mu dongosolo mapaipi, kupsyinjika ake osiyanasiyana akadali ochepa, ndipo sangathe kupirira kupanikizika kwambiri kusintha pa zochitika zinazake, kotero mitundu ina ya olowa kuwonjezera ayenera kusankhidwa kwa chipukuta misozi.

Mwachidule, PTFE cholumikizira mphira ndi chinthu chabwino kwambiri cholumikizira, chomwe chitha kupititsa patsogolo magwiridwe antchito a olowa kukulitsa labala pogwira ntchito.
