Ishidi Elibunjiwe le-PTFE / Ipuleti le-Teflon
Imininingwane Yomkhiqizo:
U-TIANJIN BEYOND uhola phambiliIshidi le-PTFE(Ishidi le-Teflon) umenzi kanye nomhlinzeki.
Ihlukaniswe ngezinhlobo ezimbili: ipuleti elibunjiwe kanye nepuleti lokujika. Ipuleti elibunjiwe lenziwe nge-polytetrafluoroethylene resin ngokubumba ekamelweni lokushisa, bese ligoqeka bese liphola. Ipuleti lokujika lenziwe nge-polytetrafluoroethylene resin ngokucindezela, ukucwiliswa bese lihlutshwa. Ukumelana nokushisa okuphezulu, ukumelana nokuguguleka, ukumelana nokucindezela okuphezulu, ukumelana ne-asidi kanye nokumelana ne-alkali; lingavimbela ngempumelelo ukuguquka nokuguga. Lingasetshenziswa ku--196℃ ~ + 260℃ ngaphandle komthwalo.
Isici Somkhiqizo:
1. Ukuthambisa okuphezulu, kungumkhawulo ophansi kakhulu wokungqubuzana ezintweni eziqinile
2. Ukumelana nokugqwala kwamakhemikhali, okunganyibiliki ku-asidi enamandla, i-alkali eqinile kanye nezinyibilikisi eziphilayo
3. Ukushisa okuphezulu nokumelana nokushisa okuphansi, ukuqina okuhle komshini.
Ukuhlolwa Komkhiqizo:
Ukusebenza Komkhiqizo:
1. Ubukhulu: 0.2mm--100mm
2. Ububanzi: 500~2800mm
3. Ubuningi obubonakalayo: 2.10-2.30 g/cm3
4. Umbala: omhlophe noma omnyama
5. Ubude: ngokwezidingo zakho
Ishidi le-PTFEiyinto enhle kakhulu yokusetshenziswa kwezinga lokushisa eliphezulu kanye nokusetshenziswa okuphansi kokungqubuzana. Inezinzuzo eziningana ezenza kube ukukhetha okuhle:
I-coefficient yayo yokungqubuzana iphansi kakhulu kuneyesithathu kunoma iyiphi into eqinile eyaziwayo
Inezakhiwo ezinhle kakhulu ze-dielectric futhi ifanele ukusetshenziswa njengezinto zokwakha amabhodi wesekethe aphrintiwe asetshenziswa kuma-microwave frequency
Ishidi le-PTFE lingenye yezinto zepulasitiki ezizinzile kakhulu ezibonisa ukubola okubonakalayo ku-260°C futhi ligcina iningi lezakhiwo zalo.
Izinga layo lokushisa eliphezulu lokuncibilika lenza kube ukukhetha okuhle njengokufaka esikhundleni se-polyethylene ebuthakathaka nephansi yokuncibilika evame ukusetshenziswa ezindleleni ezingabizi kakhulu.
Ngenxa yokungqubuzana kwayo okuphansi,Ishidi le-PTFEisetshenziselwa izinhlelo zokusebenza lapho kudingeka khona isenzo sokushelela sezingxenye ezifana nama-plain bearings, ama-slide plate, njll. Kulezi zinhlelo zokusebenza, isebenza kangcono kakhulu kune-nylon ne-acetal futhi ifana ne-UHMWPE, yize ingamelani nokuguguleka. Ukumelana kwayo okukhulu kakhulu kwenza kube yinto efanelekile yokwakha ama-electret ahlala isikhathi eside, okuyizinto eziwusizo njengezinto ezihambisanayo zama-magnets. Ku-optical radiometry, amashidi enziwe nge-PTFE asetshenziselwa ukulinganisa amakhanda kuma-spectroradiometers kanye nama-broadband radiometers (isb., amamitha okukhanya kanye nama-UV radiometers) ngenxa yamandla ayo okusabalalisa ukukhanya okudlulisayo cishe ngokuphelele. Amashidi e-PTFE anokumelana okuphezulu kokugqwala futhi asetshenziswa ezindaweni zelebhu njengezitsha zezinto ezifana ne-fluoroantimonic acid.
Ukupakisha Umkhiqizo:
Isicelo Somkhiqizo:
1. Ishidi le-PTFE lisetshenziswa kabanzi kuzo zonke izitsha zamakhemikhali nezingxenye ezithintane nemidiya ebolile, njengamathangi, ama-reactor, ulwelwesi lwemishini, ama-valve, amaphampu, izinto zokufaka, izinto zokuhlunga, izinto zokuhlukanisa kanye nepayipi loketshezi olubolile.
2. Ishidi le-PTFE lingasetshenziswa njenge-self lubricating bearing, amasongo e-piston, amasongo okuvala uphawu, ama-gasket, izihlalo zama-valve, ama-slider kanye nama-rails njll.
