Nkauj xwb PTFE (Polytetrafluoroethylene)
PTFE (Teflon) yog cov tshuaj fluorocarbon raws li cov tshuaj lom neeg thiab feem ntau yog kev tiv thaiv txhua yam, thaum khaws cov khoom siv hluav taws xob zoo heev thiab hluav taws xob rwb thaiv tsev. PTFE kuj tseem muaj cov coefficient ntawm kev txhuam yog li nws yog qhov zoo tagnrho rau ntau daim ntawv thov tsawg.
Cov khoom siv no tsis yog - tsis sib thooj thiab lees txais los ntawm FDA rau cov ntawv thov cov zaub mov. Txawm hais tias cov khoom siv tshuab hluav taws xob ntawm PTFE yog tsawg, piv rau lwm cov tshuab engineered plastics, nws cov khoom tseem muaj txiaj ntsig ntau dhau qhov kub ntau.

Qhov Zoo:
PTFE sawv rau polytetrosauruoroethylene, uas yog lub sij hawm siv tshuaj rau cov polymer (cf2) n.
Polytetrafluoroethylene (PTFE) yog ib tus neeg ua yeeb yam ntawm fluoropolymer ntawm plastics thiab muaj qhov tsis tshua muaj kev sib txhuam ntawm cov khoom sib txhuam, cov khoom insulating zoo.
PTFE yog tshuaj lom zem rau cov tshuaj feem ntau. Nws kuj tseem tuaj yeem tiv thaiv cov ntawv thov kom sov thiab nws zoo rau nws cov tshuaj tiv thaiv.
Xaiv lub rooj zaum cov khoom siv nplhaib sib dhos feem ntau yog qhov kev txiav txim siab nyuaj tshaj plaws hauvPob Pob Xaiv. Txhawm rau pab peb cov neeg siv khoom thaum lub sijhawm no, peb txaus siab muab cov ntaub ntawv ntawm cov neeg thov.
PTFE valve lub rooj tsim tawm los ntawm peb yog dav siv nyob rau hauv textile, khoom siv hluav taws xob, kev lag luam ib puag ncig, kev lag luam ib puag ncig, kev lag luam thaj, cua thiab lwm cov teb.
Cov khoom lag luam kev ua tau zoo: cov kub ua hauj, zoo acid thiab alkali ua hauj lwm thiab roj ua hauj lwm; Nrog zoo rov qab resilisence, ruaj khov thiab ruaj khov yam tsis muaj kev txwv.
