Black/ Green PTFE/ FPM + EPDM Rubber Valve Nofo mo Butterfly Valve Nofo
PTFE + EPDM faʻapipiʻiina nofoa valve paʻu gaosia e SML o loʻo faʻaaogaina lautele i le ie, eletise, petrochemical, faʻamafanafana ma le pusaaisa, vailaʻau, fau vaa, metallurgy, alamanuia mama, puipuiga o le siosiomaga ma isi fanua.
Fa'atinoga o oloa: maualuga le vevela, malosi lelei ma le alkali ma le suau'u; fa'atasi ai ma le toe fa'aleleia lelei, malosi ma tumau e aunoa ma le tafe.
PTFE+EPDM
O le liner Teflon (PTFE) e ufiufi ai le EPDM lea e fa'apipi'i i se mama phenolic malo i luga o le pito nofoa pito i fafo. O le PTFE e faʻalautele i luga o le nofoa faʻailoga ma fafo o le faʻamaufaʻailoga faʻamaufaʻailoga, e ufiufi atoa ai le EPDM elastomer layer o le nofoa, lea e maua ai le maufetuunaʻi mo le faʻamaufaʻailoga valve stems ma le tapuni tapuni.
Vevela Vallow: - 10 ° C i le 150 ° C.
Taupou PTFE (Polytetrafluoroethylene)
PTFE (Teflon) o le fluorocarbon faʻavae polymer ma e masani lava o le sili ona faʻamaʻi faʻamaʻi mai palasitika uma, aʻo faʻatumauina mea lelei faʻamalama ma eletise 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.
Vevelation stress: - 38 ° C i + 230 ° C.
Lanu: paepae
Fa'aopoopo fa'asili: 0%

Faʻaseseina o le malosi o le ptfe (polytetrafluoroothylene) ma le epdm (ethylene proplene o le vaisu i totonu o le siʻosiʻomaga i siosiomaga. O le faʻataʻitaʻiga o le tino o le ptfe faʻatasi ma le sili atu le mautu ma le mautu o le vailaʻau faia o lenei mama fofo, e masani ona maua ai o ia i luga o galuega. O lenei mama mama ua mamanuina mo le faigofie o le tuʻufaʻatasia o ituaiga o patele o valevale e aofia ai marfer, flenges, o le lupe, ufiufi taulaga ua amata amata mai i le dn400. I tua atu o lona faʻatatauina o le tusi apalai, o lenei oloa e aofia ai le faʻamaoni o Saitonu e momoli atu vaega o loʻo faʻateleina ai le fefaʻatauaiga o suavai. Pe o loʻo e galue ai i totonu o le faʻatapulaʻaina o tusitusiga fale gaosi oloa, o le fuaina o faigata o se ofisa eletise, poʻo le le mautonu o le gaioiga o le faitala o le talafatai o SPDM.
