I-PTFE gasket

Ama-gaskets e-PTFE anezakhiwo ezinhle kakhulu zokumelana nokukhasa, ukumelana nokugeleza okubandayo, ukumelana nezinga lokushisa eliphansi kakhulu, akukho ukungcola, nokufakwa kalula nokuqaqa. Ngaphansi kwamandla amancane okuqinisa ngaphambilini, ingakwazi ukumelana nokucindezela okukhulu kwangaphakathi ngisho nasezimweni zokushintshashintsha kwengcindezi. Ilungele kakhulu ama-flange anobuso bengilazi amaholoholo noma ngokungalingani futhi antekenteke kanye nezikhathi zokuvala ezishintsha izinga lokushisa. Singakhetha i-Gore, i-Klinger, i-Garlock, i-Sealon namanye amashidi anwetshiwe e-PTFE ukuze amakhasimende akhiqizele amakhasimende ama-gaskets adingekayo.

Inzuzo

Ukushisa okuphezulu ukumelana-ithempelesha yokusebenza ingafinyelela kuma-250 ℃.

Ukumelana nokushisa okuphansi-kunokuqina okuhle kwemishini; noma ngabe izinga lokushisa lehlela ku -196 ℃, lingagcina ukunwebeka okungu-5%.

Corrosion resistance-It is inert kumakhemikhali amaningi kanye ne-solvents, futhi ingamelana nama-acid aqinile kanye ne-alkalis, amanzi nama-solvents ahlukahlukene e-organic.

Ukumelana nesimo sezulu-kunempilo enhle yokuguga kumapulasitiki.

I-lubrication ephezulu-i-coefficient ephansi yokungqubuzana ezintweni eziqinile.

Ukunganamatheli-kusho ukuthi ukungezwani okungaphezulu kokuqinile kuncane futhi akunamatheli kunoma iyiphi into. Izakhiwo zayo zemishini zine-coefficient encane kakhulu yokungqubuzana, okuyi-1/5 kuphela yaleyo ye-polyethylene. Lesi isici esibalulekile se-perfluorocarbon surface. Ukwengeza, ngenxa yokuthi amandla e-intermolecular ye-fluorine-carbon chain aphansi kakhulu, i-PTFE ayinamathele.

Okungeyona ubuthi futhi okuyingozi-okune-inertia ye-physiological, njengesitsha segazi sokwenziwa nesitho esifakwe emzimbeni isikhathi eside ngaphandle kokusabela okubi.

Izakhiwo zikagesi I-Polytetrafluoroethylene inokulahleka okuphansi kwe-dielectric njalo nokulahleka kwe-dielectric ebangeni elibanzi lemvamisa, futhi inamandla amakhulu okuwohloka, ivolumu Resistivity nokumelana ne-arc.

Ukumelana nemisebe I-Polytetrafluoroethylene inokumelana kahle nemisebe (i-104 rad), futhi iyonakala ngemva kokuchayeka emisebeni enamandla amakhulu, futhi izakhiwo zikagesi nezomshini ze-polymer ziyancipha kakhulu. I-Polytetrafluoroethylene yohlelo lokusebenza ingakhiwa ngokucindezelwa noma ukucutshungulwa kwe-extrusion; kungenziwa futhi ukuhlakazeka kwamanzi ukuze kuhlanganiswe, ukucwiliswa noma ukwenza imicu. I-PTFE isetshenziswa kabanzi njengezinto ezimelana nezinga lokushisa eliphezulu neziphansi, ukumelana nokugqwala, izinto zokuvikela, okokuvikela induku, njll. emandleni enuzi, i-aerospace, electronics, ugesi, amakhemikhali, imishini, izinsimbi, amamitha, ukwakhiwa, izindwangu, ukudla nokunye. izimboni.

Ukumelana nokuguga kwasemkhathini: ukumelana nemisebe kanye nokutholakala okuphansi: ukuchayeka isikhathi eside emkhathini, ebusweni nokusebenza kuhlala kungashintshi.

Ukungasebenzi: Inkomba yomkhawulo womoya-mpilo ingaphansi kwama-90.

Ukumelana ne-acid ne-alkali: akunakunyibilika kuma-asidi aqinile, ama-alkalis aqinile kanye namakhemikhali awuketshezi angokwemvelo.

Ukumelana ne-oxidation: ukumelana nokugqwala ngama-oxidants aqinile.

Ubumuncu: Abuthathi hlangothi.

Izici zemishini ye-PTFE zithambile. Inamandla aphansi kakhulu.

I-Polytetrafluoroethylene (F4, PTFE) inochungechunge lokusebenza okuhle kakhulu: ukumelana nokushisa okuphezulu-ukushisa kokusetshenziswa kwesikhathi eside kwe-200 ~ 260 degrees, ukumelana nokushisa okuphansi-kusethambile ku–100 degrees; ukumelana nokugqwala-ukumelana ne-aqua regia nazo zonke izinyibilikisi eziphilayo; Impilo yokuguga ukumelana nesimo sezulu kumapulasitiki; i-lubrication ephezulu-ene-coefficient encane yokungqubuzana (0.04) kumapulasitiki; ukunganamatheli-okunokuqina okuphansi kwendawo ezintweni eziqinile ngaphandle kokunamathela kwanoma yiziphi izinto; okungezona ubuthi-nokungenangqondo ngokomzimba; Izakhiwo zikagesi ezinhle kakhulu, Iyinto efanelekile yokuvikela i-C-level.
