Kunezinhlobo ezimbili zeAmapuleti e-PTFE: ukubumba nokushushuluza/ukujika.Ipuleti lokubumba lenziwe nge-polytetrafluoroethylene resin ngokubunjwa ekamelweni lokushisa, bese i-sintered futhi ipholile.Ipuleti elijikayo lenziwe ngenhlaka ye-PTFE ngokucindezela, ukucwilisa, nokucwecwa.

Ipuleti le-PTFE linokumelana nokuhuzuka okungcono kakhulu kwawo wonke amapulasitiki obunjiniyela futhi lidonsa amehlo kakhulu.Uma siphakama isisindo samangqamuzana, izinto ezisetshenziswayo ezingagugi kakhulu, ngisho nangaphezu kwezinto eziningi zensimbi (njenge-carbon steel, insimbi engagqwali, ithusi, njll.).Isibonelo, amapayipi e-UHMW-pe anokuphila kwesevisi izikhathi ezingu-4-6 zamapayipi ensimbi ngaphansi kwezimo zokugqwala okuqinile nokugqoka okuphezulu, futhi ukusebenza kahle kokudlulisela kwanda ngo-20%.Ibonisa ngokugcwele ukuphakama "kokonga amandla, ukuvikelwa kwemvelo, umnotho, nokusebenza kahle okuphezulu".
Yiziphi izinzuzo zepuleti le-PTFE?
Ukumelana nezinga lokushisa eliphezulu- Izinga lokushisa lokusebenza lingafinyelela ku-250 ℃.
Ukumelana nezinga lokushisa eliphansi- Inokuqina okuhle kwemishini;ngisho noma izinga lokushisa lehla liye ku-196℃, lingakwazi ukugcina ubude obungu-5%.
Ukumelana nokugqwala- Ayisebenzi kumakhemikhali amaningi nezincibilikisi, futhi ingamelana nama-asidi aqinile nama-alkali, amanzi kanye nezincibilikisi ezihlukahlukene eziphilayo.
Ukumelana nesimo sezulu- Inempilo engcono kakhulu yokuguga phakathi kwamapulasitiki.
Ukugcoba okuphezulu- I-coefficient ephansi kakhulu yokungqubuzana phakathi kwezinto eziqinile.
Ukunganamatheli- Kuyingxabano encane kunazo zonke phakathi kwezinto eziqinile futhi akunamatheli kunoma iyiphi into.I-coefficient ye-friction yezakhiwo zemishini incane kakhulu, i-1/5 kuphela ye-polyethylene, okuyisici esibalulekile se-perfluorocarbon surface.Ukwengeza, ngenxa yokuthi amandla e-intermolecular ye-fluorine-carbon chain aphansi kakhulu, i-PTFE ayinamathele.
Ayinabuthi- Ngokungaziphathi kahle ngokomzimba, ukufakwa isikhathi eside kwemithambo yegazi yokwenziwa nezitho zomzimba ngaphandle kokusabela okubi.
Ibanga lesicelo lepuleti le-PTFE limi kanje:
1. Isebenzisa izici ze-low friction coefficient, isetshenziselwa ukumba uwoyela ogwini i-derrick slide veneer, i-dock slide veneer, i-river dam gate gate slide veneer, i-bridge telescopic support slide veneer, amathuluzi omshini ahlukahlukene, imishini eyisicefe, Igriza, i-planer sliding guideer. , njll.
2. Isebenzisa izakhiwo zayo ezingagxili, isetshenziswa embonini kashukela, embonini yezingubo, ukudla, nebhande lokuhambisa ukubhaka ugwayi, ukunyathelisa, kanye nemboni yokudaya ungqimba olunamathelayo olulwa nokugqwala lwamarola ahlukahlukene omhlahlandlela, njll.
3. Ukusetshenziswa kwama-dielectric motors kunokusebenza okuhle kakhulu futhi kusetshenziswe eziteshini zamandla ashisayo, amaseli e-electrolytic, izindandatho zokuvala, amasekhethi aphrintiwe ezintweni zikagesi kanye nezimboni zamakhompiyutha kagesi, ama-substrates agqoke ithusi, izingxenye ezihlukahlukene zokusika kanye nemishini ekhethekile.
4. Isebenzisa ngokunenzuzo ukuzinza kwayo okuhle kwamakhemikhali, ingasetshenziselwa ikakhulukazi ama-gaskets, ama-linings, ama-valve disc, nama-diaphragm ama-valve amakhulu embonini ye-petroleum, amakhemikhali, namakhemikhali, kanye nezindwangu zemikhumbi ehlukahlukene yokusabela, amathangi okugcina. , nemibhoshongo yokusabela, ipuleti lokusabalalisa, njll.
Ukusetshenziswa kwepuleti le-PTFE eliguquliwe
Ipuleti le-PTFE elishintshiweinto ekhethwayo yolayini obungagqwali, ngakho-ke yiziphi izindawo zokusetshenziswa zepuleti le-PTFE eliguquliwe?
Njengempahla yokuvala, amapuleti e-PTFE aguquliwe asetshenziswa kakhulu emishinini, e-petrochemical, ezokuthutha, endwangu, nasezimbonini zokwakha.Ngokusho kwegesi ekhethiwe permeability yepuleti PTFE ngemva kokwelashwa, ingasetshenziswa njengendlela impahla ngokuhlukana ukuze ngokukhetha ukungena igesi noma uketshezi, ikakhulukazi ukuhlunga uketshezi ezonakalisayo.Eminyakeni yamuva, ipuleti ye-PTFE eguquliwe isetshenziswe njengesitho sokwenziwa, futhi izosetshenziswa emikhakheni ehlukahlukene esikhathini esizayo, esinethemba elihle lokuthuthukiswa.
