I-PTFE O-Rings,O-Rings Ukufakwa Nokusetshenziswa

I-PTFE noma i-polymer O-Rings inokumelana okuhle kakhulu cishe nawo wonke amakhemikhali afaka ama-acids, izisekelo, uwoyela, umusi……

I-PTFE O-Rings

PTFE O-Rings Isingeniso

Ukungangenisi kwe-PTFE cishe kuwo wonke amagesi noketshezi phakathi -320 °F kanye +450 °F kungenye yezinto zayo ezingavamile uma isetshenziswa kumasistimu wokuvala we-O-Ring.Ubuqotho be-PTFE buzokwehliswa kuphela lapho kuhlangana nezinsimbi ezincibilikisiwe ze-alkaline nezinye izinhlanganisela ezine-halogenated.I-PTFE iyinto ekhethwayo yokuqinisekisa ukuhambisana kwe-O-Ring seal enendawo evalekile noma yokuvalwa ngebanga lokushisa elibanzi.

Amathiphu Wokuklama we-PTFE O-Rings

Ukuzijwayeza kwe-O-Ring yerabha okujwayelekile okufana ne-Per MIL-G-5514 ngokuvamile kuyanconywa uma kufakwa uhlobo olucindezelayo lwezinhlelo zokusebenza eziguqukayo.I-TG O-Rings nayo ingasetshenziselwa izinhlelo zokusebenza ezithile.Njengoba umehluko obonakalayo we-PTFE kanye ne-elastomeric compounds uphakeme kakhulu, ukwakheka okulandelayo nezindlela zokufaka zizoletha imiphumela engcono kakhulu yokuvala ngokusebenza nempilo yokuvala:

  • Ngokungafani nama-O-Rings enjoloba, i-PTFE O-Rings ayizwani nokwehluleka kokuvunguza, yingakho kungenzeka ukunciphisa ububanzi bezindlala.
  • I-PTFE O-Rings ayinakho ukuhambisana kwe-Rubber O-Rings;ngakho-ke kuyadingeka ukunciphisa ukuminyanisa kwezigaba okuhambisana nalokho okushiwo kunjoloba ukuze kube lula ukuhlanganisa.

Amathiphu okufaka we-polymer O-Rings

Ukuvikela i-PTFE O-Rings ekubeni i-nicked noma igoqwe ngesikhathi sokufakwa kubalulekile.I-Gouging kungenzeka ngenkathi welula ama-O-Rings phezu kwamahlombe abukhali noma imicu.Ingagwenywa ngokulayisha izindandatho phezu kwezindawo ezicijile ngokusebenzisa amathuluzi noma ngokunikeza amakhona amakhefu noma ama-radii.Ukwelula okumaphakathi, uma kungenzeka ngaphansi kuka-10%, kuyanconywa ngesikhathi sokufakwa kwe-O-Ring.Ukusetshenziswa kwamafutha ashisayo noma okugeza amanzi kusiza ukunwebeka okukhulu njengoba kudingeka.Izinguquko zedizayini noma izinqubo ezikhethekile zingadingeka ezimweni ezinwebekayo ezingaphezu kuka-20%.

I-PTFE ijwayele ukunyonyoba njengawo wonke ama-thermoplastics.Lesi sici sidinga ukubhekwa ukuze kugwenywe ukulahleka komthwalo wokuvala.Kungenzeka ukwenza ngcono umthelela wokugeleza okubandayo ngokushintsha ubukhulu njengoba kunconyiwe kumathebula.

I-PTFE O-Rings ingakhiwa kusuka ezinhlobonhlobo zezinhlanganisela ezifana ne-graphite-egcwele i-PTFE, ithusi nengilazi.Ezimweni eziningi, izimfuneko zingahlangatshezwana ne-PTFE engagcwalisiwe.

Izinzuzo ze-PTFE O-Rings

  • I-O-Rings ingesinye sezixazululo ezikahle zezinhlelo ezinengcindezi ephansi
  • Ukuhambisana kwamakhemikhali jikelele kwe-PTFE
  • Ibanga lokushisa elibanzi liphakathi kuka -320 °F kanye +500 °F
  • Izintengo ezisheshayo kanye nokushintsha ngokushesha
  • Ukukhethwa kukasayizi obanzi we-O-Rings phakathi kuka-0.110″ no-~40″;usayizi okhethekile uyatholakala uma uceliwe
  • Vacuum ukuya kungcindezi ephezulu, uma isetshenziswa ngokuhambisana neringi yokusekelayo efanelekile
