I-PTFE Lined Flexible Rubber Expansion Joint
Incazelo
I-PTFE enezingqimba zenjoloba enwetshiwe inezici zokunciphisa ukudlidliza, i-anti-corrosion, ukumelana ne-asidi ne-alkali, ukumelana nokushisa okuphezulu, ukumelana nezimo nokukhuhla, ikakhulukazi okusetshenziselwa ukususwa kwamapayipi, ukuguqulwa kobukhulu kanye nokuxhumeka kwengxenye yokudlidliza, ingasetshenziswa njengokuhlinzeka nokukhipha amanzi. ipayipi lomcengezi, ubunjiniyela bamakhemikhali, ukugqwala, okokusebenza kwemoto yethangi le-vulcanization, nokunye ukusetshenziswa okukhethekile.
I-PTFE ifushane nge-Polytetrafluoroethylene, eyaziwa nangokuthi i-Teflon, 4F.I-PTFE inozinzo oluhle kakhulu lwamakhemikhali nokumelana nokugqwala, ingenye yezinto ezingcono kakhulu zokumelana nokugqwala emhlabeni, ngaphandle kwe-metallic sodium ne-fluorine ewuketshezi, i-PTFE ukumelana nawo wonke amakhemikhali, asetshenziswa kabanzi kuzo zonke izindawo ezigqwalayo.Ngaphandle kwalokho, inendawo enhle yokubeka uphawu, impahla yokugcoba ephezulu, impahla kagesi efaka insulating, ukumelana nokuguga okuhle, ukumelana nezinga lokushisa (kungakwazi ukusebenza isikhathi eside phakathi -180 ℃ kuya ku-250 ℃).
Izici zomkhiqizo wamajoyinti wokunweba werabha anemigqa ye-PTFE:
Ukumelana nokushisa okuphezulu: izinga lokushisa lokusebenza lifinyelela ku-250 ℃.
Ukumelana nezinga lokushisa eliphansi: inokuqina okuhle kwemishini, noma izinga lokushisa lehla laya ku--196 ℃, ingagcina ukuphakama okungu-5%.
Ukumelana nokugqwala: ukumelana namakhemikhali amaningi.
