Xoom Leakage PTFE Valve Rooj Rooj Npauj Npaim Valve Qhov DN50 - DN 600 Nws
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 kub thiab txias: - 38 ° C txog + 230 ° C.
Xim: dawb
Torque ntxiv: 0%

Nitrile roj hmab muaj nws tus kheej zoo - nthuav cov khoom, abrasion tsis kam thiab hydrocarbon - resistant zog. Nws tuaj yeem siv los ua cov khoom siv dav dav rau dej, nqus tsev, kua qaub, ntsev, alkali, roj, roj, butter, roj hydraulic, glycol, thiab lwm yam. Tsis tuaj yeem siv rau hauv qhov chaw xws li acetone, ketone, nitrate, thiab fluorinated hydrocarbons. |

Qhov zoo:
PTFE stands rau PolyTetraFluoroEthylene, uas yog lub sij hawm tshuaj rau cov polymer (CF2)n.
Polytetrafluoroethylene (PTFE) yog ib tug thermoplastic tswv cuab ntawm fluoropolymer tsev neeg ntawm cov yas thiab muaj ib tug tsawg coefficient ntawm kev sib txhuam, zoo heev insulating zog.
PTFE yog chemically inert rau feem ntau cov khoom. Nws kuj tuaj yeem tiv taus cov ntawv thov kub kub thiab nws paub zoo rau nws cov khoom tiv thaiv-stick.
Xaiv cov khoom siv lub nplhaib zoo yog feem ntau yog qhov nyuaj tshaj plaws kev txiav txim siab hauv Pob Valve Kev xaiv. Txhawm rau pab peb cov neeg siv khoom thaum lub sijhawm txheej txheem no, peb txaus siab muab cov ntaub ntawv ntawm cov neeg siv khoom thov.
PTFE valve rooj zaum tsim los ntawm Teb Chaws Asmeskas 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, ntawv kev lag luam, qab zib kev lag luam, compressed cua 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.
