Mo masini e le o u'amea e pei o tioata, ceramics, graphite, plastics, ma isi, e iai sona aafiaga uiga ese.E mafai ona totogi ma faapaleni mea sese e mafua mai i faaletonu, faʻagasologa faʻainisinia, faʻamaʻi faʻaletonu, faʻapipiʻiina misalignment, ma isi, faapaleniina le malosi preload le tutusa, ma foia lelei faafitauli leakage o nofoaga eseese i lalo o tulaga faigata.
Ituaiga o gaskets PTFE
1. Gasket PTFE mama
PTFE gaskets mama o gaskets mafolafola, gaskets V-foliga, piston mama, polo valve gaskets, ma isi, lea e masini liliu pe tipi mai.PTFE tootoo, PTFE paipa, maPTFE pepa, lea e tete'e ai le corrosion, anti-matua, ma le le-conductive.Uiga lelei.E mafai ona iai le malosi fa'ainisinia lelei i le va o le -100°C ma le 100°C.
O le isi vaega o lenei oloa e mama.Mo nisi mea e mafai ona oʻo mai i le faʻafesoʻotaʻi ma ia, gaskets PTFE mama o le a le mafua ai so o se filogia ia i latou.O lenei tulaga lelei e faʻaaogaina tele i meaʻai ma vailaʻau.
2. Suia PTFE gasket
O lenei ituaiga o PTFE gasket e aofia ai vaega e lua, graphite tumu ma tioata fiber-tumu.
graphite-tumu tetrafluoroethylene gasket o le PTFE ma graphite o se faʻatumu mo se faʻafefiloi toniga atoa ona sosoo ai lea ma se vevela maualuga.O lenei gasket PTFE e sili ona lelei faʻamaufaʻailoga ma compressibility.
PTFE gaskets fa'atumu alava tioata fa'aaoga alava tioata e fa'atumu.O lenei mea o loʻo i ai mea faʻaleleia lelei ma e sili atu nai lo mea masani i le faʻatinoga.E tete'e fa'alavalava ma fa'ama'i fa'ama'i ma e fetaui lelei mo pisinisi pepa ma mea'ai.
3. Fa'alautele PTFE Gasket
O gaskets PTFE faʻalauteleina e mafai ona tetee atu i le malulu ma fetolofi, ma maua le avanoa o le faigofie ona faʻapipiʻi, aemaise lava le gafatia e faʻafefe ai le vevela ultra-maualalo.O le faʻamaufaʻailogaina o lenei mea e matua faʻatuatuaina, ma e faʻasalaina foi i le pa.E sili ona fetaui lelei mo luga o luga.
8 lelei o PTFE gasket
1. O le PTFE gasket lava ia o loʻo i ai le maualuga o le corrosion resistance, faʻamautu galuega faʻaletino, maualuga ma maualalo le vevela, ma ausia lona faʻamaufaʻailoga lelei.E ala i le suia o le malosi faʻalavelave o le fusi uʻamea faʻafefeteina, e mafai ona suia le mamafa (maaa) o le gasket faʻapipiʻi e fetaui ma manaʻoga o talosaga eseese.E faʻaaogaina lautele i petrochemical, masini, eletise eletise, metallurgy, fau vaa, vailaʻau, malosi atomic, ma alamanuia aerospace.
2. PTFE gaskets e tau-tetefe, ma o le PTFE o loʻo i ai le olaga matua sili ona lelei i totonu o palasitika.O le PTFE gasket lava ia o loʻo i ai le maualuga o le corrosion resistance, faʻamautu galuega faʻaletino, maualuga ma maualalo le vevela, ma ua ausia le faʻamaufaʻailoga lelei.E masani ona faʻaaogaina i le suauu, vailaʻau, vailaʻau, eletise eletise, ma fale uʻamea.
3. E le pipii le gasket PTFE.O le PTFE o loʻo i ai le faʻalavelave sili ona laʻititi i luga o mea mautu ma e le pipii i soʻo se mea.
4. PTFE gaskets e tetee i le maualalo o le vevela ma maua ai le malosi faʻainisinia lelei;e tusa lava pe pa'ū le vevela i -196 ° C, e mafai ona latou tausia le 5% elongation.E fetaui lelei mo le faʻamaufaʻailogaina o vaega e matua suia ai le vevela ma le mamafa.O se fa'amaufa'ailoga fa'amaufa'ailoga mo feso'ota'iga flange e pei o paipa, valve, pamu, fa'aliliu vevela, olo, manholes, ma pu lima.
5. O galuega tauave ma tulaga lelei o gaskets PTFE e faapea.O le ala talafeagai e aofia ai toetoe o vaega uma o vailaʻau e pei ole vai, suauʻu, vaifofo acid, fofo alkali, ma isi.
6. PTFE gasket e le oona ma o le PTFE e physiologically inert, ma e leai ni faʻalavelave faʻalavelave e pei o vaʻa toto ma totoga faʻapipiʻiina i totonu o le tino mo se taimi umi.
7. PTFE gaskets e teteʻe i corrosion, inert i le tele o vailaau ma solvents, ma e mafai ona tetee malosi acids ma alkalis, vai ma solvents organic eseese.O lenei gasket o loʻo i ai le faʻapipiʻiina lelei ma le faʻaleleia o le faʻatinoga, faʻamaufaʻailoga tele-channel, ma nisi o galuega faʻamalosi, lea e mafai ona faʻaumatia ai le aʻafiaga o le mamafa, suiga o le vevela, ma le vibration masini.
8. I lalo o le maualuga o le vevela, maualalo le vevela, maualuga le gaogao, teʻi vibration, ma isi suiga faʻataʻamilomilo ma tulaga faigata eseese, faʻamautu lona faʻamaufaʻailoga sili ona lelei.I le suia o le tuufaatasiga o meafaitino o le gasket, e mafai ona foia le faafitauli o le tafia o vailaau o le gasket e ala o faasalalauga eseese.E le faʻapipiʻiina le pito i luga o le flange, lea e faafaigofie ai le tausiga ma le suia.
9. PTFE gaskets e tetee atu i le maualuga o le vevela, ma e mafai ona faʻaaogaina le PTFE i le vevela galue o le 250 ° C.
O a mea e tatau ona mafaufau i ai pe a filifilia gaskets PTFE
PTFE gaskets o loʻo faʻaaogaina i le tele o ituaiga meafaigaluega.Ina ia faʻamautinoa lelei le faʻatinoga, o mea taua e tatau ona iloiloina i le filifilia o gaskets PTFE e faʻapea:
1. Medium: O le fesili o le alalaupapa e fai si faigofie.Na'o le mana'omia le fa'alogo i nisi o fesili fa'apitoa fa'apitoa, e pei o fa'aulaula galuega u'amea e masani ona fa'aaogaina vai-glycol ma le phosphate ester hydraulic oil.
2. Temperature: O le NBR malulu malulu e tatau ona mafaufau pe a oʻo i le 20 ~ 40℃ le vevela.Ole mea lautele ole NBR ole a faʻamaʻaʻaina mea i lalo ole siosiomaga maualalo-vevela, e mafua ai le leaka.
3. Aafiaga o le mamafa: A amata ma tapunia le masini faufale, e sili atu le mamafa o lona aafiaga nai lo le mamafa o galuega masani, o lea e masani ona faʻaaogaina e avea ma faʻamaufaʻailoga autu ma le aʻafiaga o le aʻafiaga ma le faʻaogaina o le avanoa HBY poʻo le SPGW faʻatasi ai ma le faʻamalosi malosi o le e oʻo atu i le 70MPA.
