Dub / Ntsuab PTFE / FPM + EPDM Roj Hmab Valve Rooj rau Npauj Npaim Valve Rooj
PTFE + EPDM compounded roj hmab valve rooj zaum tsim los ntawm SML yog dav siv nyob rau hauv textile, fais fab chaw nres tsheb, petrochemical, cua sov thiab tub yees, tshuaj, shipbuilding, metallurgy, lub teeb kev lag luam, kev tiv thaiv ib puag ncig thiab lwm yam teb.
Cov khoom ua tau zoo: kub tsis kam, zoo acid thiab alkali tsis kam thiab roj kuj; nrog zoo rebound resilience, sturdy thiab check tsis muaj to.
PTFE+ EPDM
Teflon (PTFE) liner overlays EPDM uas yog sib koom ua ke rau lub nplhaib phenolic nruj ntawm lub rooj zaum sab nraud. Lub PTFE txuas rau lub rooj zaum thiab sab nraud flange foob txoj kab uas hla, tag nrho npog EPDM elastomer txheej ntawm lub rooj zaum, uas muab cov resilience rau sealing valve stems thiab kaw disc.
Qhov KubTiab Kub: - 10 ° C txog 150 ° C.
Virgin PTFE (Polytetrafluoroethylene)
PTFE (Teflon) yog fluorocarbon raws li polymer thiab feem ntau yog cov tshuaj tiv thaiv zoo tshaj plaws ntawm tag nrho cov yas, thaum tuav cov khoom zoo thermal thiab hluav taws xob rwb thaiv tsev. PTFE kuj muaj cov coefficient tsawg ntawm kev sib txhuam yog li nws yog qhov zoo tagnrho rau ntau daim ntawv thov torque tsawg.
Cov khoom no tsis yog - paug thiab lees txais los ntawm FDA rau cov ntawv thov zaub mov. Txawm hais tias cov khoom siv kho tshuab ntawm PTFE tsis tshua muaj, piv rau lwm cov khoom siv hluav taws xob, nws cov khoom tseem muaj txiaj ntsig zoo rau ntau qhov kub thiab txias.
Qhov KubTiab Kub: - 38 ° C rau + 230 ° C.

Nyob rau hauv lub plawv ntawm peb cov khoom lag luam zoo tshaj yog nws cov ntaub ntawv tshwj xeeb. PTFE, nto npe rau nws cov tshuaj lom zem tsis zoo thiab hnav tsis zoo, tsim cov khoom sib xyaw ua ke ntawm nws txoj kev muaj peev xwm los tuav kev ncaj ncees thiab kev ua tau zoo ntawm cov ntawv thov. Los ntawm DN50 rau DN600 chaw nres nkoj, peb Teflon Npauj Npaim Valve yog engrotures, ua rau kev tiv thaiv hluav taws xob, kev tiv thaiv lub teeb, thiab kev tiv thaiv lub teeb, thiab kev tiv thaiv lub teeb, thiab ib puag ncig. Tus qauv tsim ntawm peb Teflon npauj npaim Valve tsom rau kev teeb tsa thiab txij nkawm, tsom rau txo qis qis thiab nce nyiaj. Txawm hais tias koj tau siv Wafer hom nruab nrab Sealing Npauj Npaim Valve, peb cov khoom lag luam tuaj yeem ua rau muaj kev cuam tshuam kev cuam tshuam thiab kho tus nqi. Tsis tas li ntawd, qhov tsis muaj ntawm tus pin hauv peb ib nrab ncej ob ncej ob txoj haujlwm ua haujlwm thiab txhim kho lub valve tag nrho.
