Premium PTFE EPDM Fa'apipi'i Fa'alava Valve Lisi
I totonu o le lalolagi o mea tau fale gaosi oloa ma valve, o le faʻamaoni ma le faʻamaoni o vaega vaega e sili ona taua i le manuia o le faʻaogaina o le faiga. Sansheng Fluorine Plastics o lo'o fa'ailoa mai lona fofo fa'ato'a - o le PTFE EPDM fa'apipi'i fa'alava ole pepe. O lenei oloa o loʻo faʻatusalia le tumutumu o tekinolosi nofoa valve, tuʻufaʻatasia le kemisi faʻamalosi o le PTFE (Polytetrafluoroethylene) ma le maufetuunaʻi o le paʻu EPDM. Fuafuaina e fa'amalieina le tele o ta'amilosaga mai le DN50 e o'o atu i le DN600, o lenei liner e fa'amautinoaina le fetaui lelei mo le tele o fa'aogaina o valve butterfly.
O le fa'afouga i tua o le PTFE EPDM fa'apipi'i fa'alava ole pepe o lo'o ta'oto i lona mea tu'ufa'atasi. Virgin PTFE, e lauiloa foi o Teflon, e lauiloa i lona tetee atu i vailaʻau e le mafaatusalia, e mafai ona tatalia siʻosiʻomaga faigata e feagai ma le tele o gaioiga faʻapisinisi. O lenei polymer fluoropolycarbon-fa'avaeina e fa'atumauina lelei mea e fa'amama ai le vevela ma le eletise, ma avea ai ma mea e filifilia mo fa'aoga mana'omia. A tu'u fa'atasi ma le EPDM, o se pa'u e iloa mo lona umi ma le elasticity, o le i'uga o se va'a nofoa laina e maua ai le leai o se fa'aogaina i lalo o le tele o le vevela ma le mamafa. O lenei tu'ufa'atasiga tulaga ese e fa'amautinoa ai e le na'o le malosi o le liner, ae e mafai fo'i ona fetu'una'i, fa'afeiloa'i sina suiga itiiti e aunoa ma le fa'afefeteina o le fa'amaufa'ailoga sa'o. Ua mamanuina ina ia ausia tulaga maualuga o le lelei ma le faatinoga. Pe mo vai vai, fa'agaioiina vaila'au, po'o so'o se talosaga e mana'omia ai le felauaiga o sua fa'afefete, e folafola mai e lenei liner e fa'aolaina le fa'atinoga e le mafaatusalia. O faʻamatalaga faʻafesoʻotaʻi mo faʻamatalaga tuusaʻo ma le lagolago e tuʻuina atu e ala i WhatsApp / WeChat i le +8615067244404, faʻamautinoa e maua vave e matou tagata faʻatau i la matou 'au faʻapitoa. Faatasi ai ma le Sansheng Fluorine Plastics, o loʻo e filifilia se paaga e tuuto atu i le tulaga lelei ma le faʻafouina i le fanua o le palasitika fluorine ma le tekinolosi nofoa valve.

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 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.
