Maualuluga-Uuality Bray PTFE+EPDM Butterfly Valve Liner - DN50-DN600
I le tulaga faigata o faʻagasologa faʻapisinisi ma faʻaoga, o le faʻamaoni ma le faʻamaoni o vaega valve e tu maualuga. O le Sansheng Fluorine Plastics o lo'o fa'alauiloa mai ai le tumutumu o fa'amaufa'ailoga fa'amaufa'atasi ma la matou Bray PTFE + EPDM Butterfly Valve Liner. Fuafuaina ma le toto'a e tautua ai se fa'amoemoe e lua, o lenei oloa e fa'aipoipo i le fa'a'ese'esega fa'ama'i e le mafaatusalia o le PTFE (Polytetrafluoroethylene) fa'atasi ai ma le fa'apitoa o le vevela ma le elasticity o le EPDM (Ethylene Propylene Diene Monomer). O se feso'ota'iga lelei atoatoa e maua ai se nofoa va'a e le gata ina folafola ae fa'aolaina le fa'atinoina o le leakaina i luga o le tele o fusi o alaleo mai le DN50 i le DN600.
O le fa'aaogaina o uiga fa'anatura o le Virgin PTFE, lea e ta'ua lautele o Teflon, e le mafaatusalia a tatou va'a laina i lo latou tete'e atu i mea pala. O le mea lea ua avea ai i latou ma aseta taua i alamanuia o lo'o fa'aalia ai vaila'au o se mea moni i aso uma. PTFE, faʻatasi ai ma le maualuga o le molecular weight polymer structure, faʻamautinoaina o vaʻa vaʻavaʻa taʻitasi e maua ai se pa puipui e le mafai ona faʻasaga i vai, kasa, ma e oʻo lava i vailaʻau sili ona malosi. O lenei tuufaatasiga meafaitino malosi, tuʻufaʻatasia ma le fetuutuunaʻi ma le faʻaleleia o loʻo ofoina mai e le EPDM, faʻaleleia le faʻaogaina o le laina i le fesuiaiga o le vevela ma le mamafa o masini, faʻamautinoa le umi ma le faʻamaoni.O le Sansheng Fluorine Plastics Bray PTFE + EPDM Butterfly Valve Liner e sili atu nai lo se vaega. O se molimau i le tulaga fa'ainisinia, ua fuafuaina e fa'amalieina mana'oga faigata o pisinisi fa'aonaponei. Mai la'au petrochemical i fale gaosi mea'ai ma meainu, o nei laina e fa'amautinoa le fa'atinoina o le fa'amaoni, saogalemu, ma le lelei. O la matou tautinoga i le tulaga lelei ma le faʻafouina e faʻamautinoa ai o oloa taʻitasi e gaosia ma le saʻo, ofoina atu le faʻatinoina ma le filemu o le mafaufau i a matou tagata faʻatau. Talia le lumanaʻi o tekinolosi valve i aso nei ma iloa le eseesega i fofo faʻamaufaʻailoga maualuga a Sansheng Fluorine Plastics.

Zero Leakage PTFE Valve Nofo Butterfly Valve Vaega DN50 - DN600
Taupou PTFE (Polytetrafluoroethylene)
PTFE (Teflon) o le fluorocarbon faʻavae polymer ma e masani lava o le sili ona faʻamaʻiina faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻavela ma eletise. O le PTFE e iai foʻi le maualalo o le feteʻenaʻiga o lea e lelei mo le tele o faʻaoga maualalo.
O mea nei e le fa'aleaga ma talia e le FDA mo mea'ai. E ui lava o mea faʻainisinia o le PTFE e maualalo, faʻatusatusa i isi palasitika faʻainisinia, e tumau pea lona aoga i luga o le lautele o le vevela.
Va'aiga vevela: -38°C i le +230°C.

O le pa'u nitrile e lelei lona lava - fa'alauteleina meatotino, abrasion tete'e ma hydrocarbon - mea e tete'e. E mafai ona faʻaaogaina e avea o se mea lautele mo vai, vacuum, acid, masima, alkali, gaʻo, suauu, pata, suauʻu hydraulic, glycol, ma isi. E le mafai ona faʻaaogaina i nofoaga e pei o le acetone, ketone, nitrate, ma fluorinated hydrocarbons. |
