Fluorinated ethylene propylene (FEP).tuaj yeem piav qhia tias yog fluoropolymer resin muaj feem ntau ntawm lub cev zoo heev.Cov khoom siv tshuaj lom neeg thiab hluav taws xob ntawm PTFE tab sis tuaj yeem ua tiav siv cov khoom siv ua cov thermoplastics.
FEP tshav kub shrink yob npog yog qhov zoo tshaj plaws uas yuav tsum tau muaj kev tiv thaiv los ntawm qhov chaw tsis zoo.Nws txoj kev yooj yim ntawm kev teeb tsa txo kev txij nkawm thiab nqes sij hawm.Nws kuj muab kev tiv thaiv corrosion zoo heev, tiv thaiv kev tsim txom ntawm lub cev, kev poob siab thiab kev puas tsuaj, cov khoom siv hluav taws xob zoo, thiab siab purity thiab transparency.Shrinkage yog kwv yees li 20%.Lub shrinkage kub yog 350 ° F. Lub zog tuav yog 5-8 psi thiab nto tiav yog 40 micro ntiv tes.Qhov ntsuas kub tsis tu ncua rau polymer FEP yog 400 ° F. Txawm li cas los xij, nyob rau hauv cov khoom siv siab, qhov no poob ntau heev.Rau cov ntawv yob npog qhov chaw siab dua, qhov kub yuav tsum tsis pub tshaj 200 ° F.Nyob rau hauv cov ntawv thov siab dua thiab kub, yuav tsum siv lub raj etched ID nrog cov nplaum.
Txhawm rau nruab FEP yob npog koj yuav tsum xub xaiv qhov ze tshaj txoj kab uas hla loj dua qhov xav tau loj.Xaiv qhov ntev raws li kwv yees li 3% shrinkage hauv qhov ntev.Rau yob npog, tseem tso cai ntxiv 2 "-3" ntev rau qhov kawg cuffs.Txiab los yog rab riam ntse siv tau los txiav cov raj.Txhawm rau txo cov tubing mus rau ib feem, thov 250-400 ° F, nyob ntawm daim ntawv thov.Qhov no tuaj yeem ua tau los ntawm kev siv cov cua kub qhov cub lossis cov phom cua kub ua lag luam.Rau yob npog, nws raug nquahu kom siv ob rab phom cua kub, ntawm ob sab ntawm cov menyuam, siv.Cov menyuam thiab lub raj yuav tsum sib npaug sib npaug thaum siv cov cua sov.
