PTFE fa'apipi'i O-Rings Talosaga

Aegis, Aflas, Butyl, Fluorosilicone, Hypalon poʻo soʻo se mea faʻapipiʻi atonu e manaʻomia e lau talosaga patino.Coated ma Encapsulated O-Rings o se isi filifiliga foi:

Faʻapipiʻiina pe faʻapipiʻiina - O-Rings faʻapipiʻiina o loʻo faʻapipiʻiina le PTFE, faʻatasi ai ma le faʻapipiʻi faʻapipiʻi i le O-Ring (e masani lava Silicone poʻo Viton poʻo NBR).O-Rings fa'apipi'iina o se O-Ring (e masani lava Silicone po'o Viton) e ufiufi i se paipa PTFE.PTFE faʻapipiʻi o O-Rings o se faʻapipiʻi maualalo-fesoʻotaʻi lelei lea o le fetuutuunai faʻagaioiga o se iloiloga tele.O le O-Ring faʻapipiʻiina e amio e pei o se sua viscous maualuga, soʻo se mamafa i luga o le faʻamaufaʻailoga e faʻasalalau i itu uma.Coated O-Rings e maua i le tele o lanu eseese.
Fa'apipi'i fa'apitoa o meafaitino - Afai e iai sau mana'oga mo se fa'aputuga fa'apitoa e le o le tulaga masani o pisinisi, e mafai ona matou galulue fa'atasi ma tagata gaosi oloa e gaosia lena fa'aputuga fa'apitoa e fetaui ma ou mana'oga.
Mil-Spec, Mil-Std poʻo Milspecs o se faʻataʻitaʻiga a le Iunaite Setete o loʻo faʻaaogaina e ausia ai sini faʻatulagaina e le US Department of Defense.E mafai e Rockets Seals ona maua so'o se Mil-Spec e ala i la matou feso'ota'iga tele o fa'atau oloa.
FDA mea'ai vasega mea'ai, igoa mai fafo, USP, KTW, DVGW, BAM, WRAS (WRC), NSF, Underwriters Laboratories (UL), Aerospace (AMS) ma Mil-Spec - Rocket ua i ai le poto masani i le ausia o ou manaʻoga i tulaga uma o alamanuia.

e mafai ona e filifili e mulimuli i lanu po o isi lanu sili atu.

E sili atu ona lauiloa i le igoa Teflon, polytetrafluoroethylene (PTFE) e maua ai se mea e le pipii i mea kuka, fao fao, mea e teu ai lauulu, ie / kapeta togafitiga, ma lau mata tioata.Ae ui i lea, o loʻo vaʻaia e le au gaosiga le faʻateleina o faʻamanuiaga mai le faʻaaogaina o le PTFE o se auala e gaosia ai mama O-mama.O-mamafausia e fa'aaoga ai le PTFE e tu'uina atu ai le fa'amaluina o le vevela ma le vaila'au, ma e mafai fo'i ona latou tete'e fe'ese'esea'iga ma vai.

PTFE VERSUS TEFLON

E ui ina eseese i latou i le faʻailoga, o le PTFE ma Teflon e faʻasoa se tupuaga masani ma meatotino.

PTFE

O le PTFE o se polymer gaosia e maua mai i vailaʻau faʻapipiʻi i le va o le carbon ma le fluorine, faʻaaogaina le faʻaogaina o radical free e polymerize i le tetrafluoroethylene.O lenei mea na maua faʻafuaseʻi i le 1938, ina ua taumafai le DuPont chemist Roy J. Plunkett e fatu se ituaiga fou o le pusaaisa, ma faʻafefiloi faʻatasi nei mea e aunoa ma le iloaina o le tali e mafua ai.

TEFLON

Kinetic Chemicals, o se kamupani faipaaga i le va o DuPont ma General Motors, faʻailoga PTFE i lalo o le igoa igoa Teflon i le 1945. O lona uiga, Teflon o le PTFE.Ae ui i lea, o loʻo maua foi le PTFE i lalo o le tele o isi igoa faʻailoga, e pei o:

Daikin-Polyflon
Fluon
Dyneon

MEATOAGA

E tele mea totino e iloagofie ai le PTFE mai isi mea, e aofia ai:

Fa'atauva'a maualalo: O le PTFE o lo'o i ai le lona tolu pito sili ona maualalo fa'atasi o so'o se mea e iloa e le tagata, o lona uiga e moni lava.
Fa'atino ile maualuga ole vevela: Fa'amauina ile 600K, liusuavai le PTFE ile 327ºC po'o le 620ºF, ma e lelei fo'i le galue i le vevela e maualalo ifo i le −268ºC po'o le −450ºF.
Tetee vai: O lopa vai i luga o le PTFE, o lona uiga o luga e togafitia i lenei mea e tetee i le faʻamaʻiina.
Nonreactive: PTFE e le tali atu i le tele o mea pala, ma fa'aoga lelei mo le fa'aoga i paipa, valve, fa'amaufa'ailoga, ma O-mama.

O LE TULAFONO MAUGA A LE PTFE

O le maualuga o le vevela (-1,000F i le +4,000F), nonreactivity, vai faʻafefe, ma le maualalo o feteʻenaʻiga o meatotino a le PTFE e avea ma mea lelei e fausia ai mama O mo le faʻaaogaina i le tele o ituaiga talosaga.O nei meatotino ua avea ai PTFE O-mama o se filifiliga lelei mo talosaga e tetee i le tau faapea foi ma talosaga e aofia ai le eletise ma le vevela.

Ona o lo latou mamafa,PTFE O-mamae le o “liusuavai”—nai lo o lea, e oomi ma fa'alumaina e maua ai foliga talafeagai.

FA'ailoga TEFLON/PTFE

O-mamafaia i le PTFE o loʻo i ai i le tele o ituaiga o alamanuia talosaga e manaʻomia ai faʻamaufaʻailoga e mafai ona tuʻua faigata.O-mama PTFE o loʻo faʻaalia i le tele o talosaga e faʻaalia i tulaga lamatia nei:

Talosaga pito i luga	Vaivaiga Fa'ainisinia
I fafo Lubricants Hydrocarbons Aisa Alkali Lafoa'i 'ava malosi Ketones Ausa Fa'aaisa	Faamaufa'ailoga Vacuum maualuga Fa'amau Fa'amau Fa'amau Fa'amau Fa'amau Ausa Super-Avela
