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.

Tsim los ntawm kev ua ke zoo ntawm PTFE (polystetrafluoroethylene) thiab ethylene diene mones monomer roj hmab), lub nplhaib sealcher lees paub kev ua tau zoo. Lub PTFE tivthaiv ntseeg tau cov neeg swb, tshuaj lom neeg - tiv taus nto rau kev tswj xyuas kev ua kom huv thiab tiv thaiv kev paug, tshwj xeeb hauv kev ua paug. Hloov siab, ntxiv rau ntawm EPDM txhawb cov nplhaib sib khi lub zog rau kev hloov pauv kub thiab cov kev pabcuam hnyav, ua kom lub neej pabcuam kom nruj txawm tias nyob hauv qab cov kev mob siab. Peb huv huv Seb nws dej, roj, roj, roj roj, lossis txawm tias muaj kev sib cav sib ceg ntawm cov nyom. Lub wafer thiab flange xaus kev sib txuas, txuas nrog nws qhov sib xyaw nrog ob tog pneumatic yam tsis muaj pins thiab txij nkawm ncaj thiab sib kho ncaj qha thiab tsis muaj teeb meem - DAWB. Txhim kho los ntawm nws qhov siab - kev ua yeeb yam nyob rau hauv huab kev mob, cov khoom no yog qhov tsis tseem ceeb rau kev lag luam npaj ua haujlwm thiab kev ntseeg tau.
