I-PTFE O-Ring

I-Polytetrafluoroethylene (PTFE) iyi-polymer enesisindo samangqamuzana aphezulu, okungenye yezinto zepulasitiki eziguquguquka kakhulu ezaziwayo futhi eziwusizo kuhlu olukhulu lwemikhiqizo ekusetshenzisweni okungafakwa kwezinye izinto.

I-Polytetrafluoroethylene (i-PTFE ngamafuphi) iyirabha yokwenziwa enokungqubuzana okuphansi osekunesikhathi eside isetshenziswa ekufakweni kwesivalo sezinto ezihlukahlukene ezihlanganisa amagesi, uketshezi, namakhemikhali.

I-PTFE O-Ring Temperature Range

Nakuba i-PTFE inezakhiwo eziphansi zomshini uma kuqhathaniswa namanye amapulasitiki, ukumelana kwamakhemikhali wempahla kuhambisana nekhono layo lokumelana nezinga lokushisa elibanzi (-100oF kuya ku-+400oF) kuvumela ama-o-ring we-PTFE ukuthi anikeze ukumelana ngempumelelo nesimo sezulu kanye nogesi kanye nokushisa. ukwahlukanisa.

Ngenxa yokuthi i-PTFE iyimpahla eminyene kangako, ayikwazi “ukuncibilika icutshungulwe” – kufanele icindezelwe futhi ifakwe i-sinter ukuze yakhe izimo eziwusizo (njengama-o-rings).

Khulisa Izakhiwo Zemishini NgamaBanga AgcwalisiweAboniswe kuthebula elingenhla, ama-o-ring we-PTFE anokulimala okuthile komshini uma kuqhathaniswa namanye amapulasitiki.Uma kudingekile, lezi zakhiwo zingathuthukiswa ngokungeza ama-filler, afana nalokhu:
