PTFE Lined Flexible Rubber Expansion Joint
Tlhaloso
PTFE lined rabara katoloso ea manonyeletso e na le likarolo tsa phokotso ea ho sisinyeha, anti-corrosion, acid le alkali resistance, mocheso o phahameng oa ho hanyetsa, flexible le rub resistance, haholo-holo e sebelisetsoang phallo ea liphaephe, phetoho ea dimension le karolo ea vibration, e ka sebelisoa e le phepelo le drainage. pipeline bakeng sa beisine, boenjiniere ba lik'hemik'hale, kutu, lisebelisoa tsa koloi ea vulcanization, le ts'ebeliso e 'ngoe e khethehileng.
PTFE e khutsufetse bakeng sa Polytetrafluoroethylene, e tsejoang hape e le Teflon, 4F.PTFE e na le botsitso bo botle ba lik'hemik'hale le ho hanyetsa kutu, ke e 'ngoe ea lisebelisoa tse ntle ka ho fetisisa tsa ho thibela kutu lefatšeng, ntle le metallic sodium le fluid fluorine, PTFE e hanyetsa lik'hemik'hale tsohle, e sebelisoa haholo libakeng tsohle tse senyang.Ntle le moo, e na le thepa e ntle ea ho tiisa, thepa e phahameng ea ho tlotsa, thepa e sireletsang motlakase, ho hanyetsa botsofali hantle, ho hanyetsa mocheso (e ka sebetsa nako e telele pakeng tsa -180 ℃ ho 250 ℃).
Likarolo tsa sehlahisoa sa PTFE e nang le likhoele tsa katoloso ea rabara:
Ho hanyetsa mocheso o phahameng: mocheso o sebetsang o fihla ho 250 ℃.
Ho hanyetsa mocheso o tlase: e na le ts'ebetso e ntle ea mochini, leha mocheso o theohela ho -196 ℃, e ka boloka bolelele ba 5%.
Corrosion resistance/ Ketso ya ho hanyetsa: ho hanyetsa dikhemikhale tse ngata.
