PCTFE los yog CTFE (keeb kwm hu ua Kel-F*) muaj ntau yam khoom zoo ib yam li lwm yam fluoropolymer xws li PTFE, FEP los yog PFA, tab sis yog mechanically superior hauv rigidity (tsis deform yooj yim), thiab muaj roj permeability tsawg heev.Nws qhov ruaj khov qhov ntev ua rau nws txaus nyiam siv los ua ib feem ntawm cov txheej txheem uas yuav tsum muaj qhov kub thiab txias thiab tshuaj tiv thaiv ntawm fluoropolymer.PCTFE qhia tau hais tias muaj zog compressive thiab tsawg deformation nyob rau hauv load.Txawm li cas los xij, nws tus nqi txheeb ze yog ib qho ntawm cov kev xav tseem ceeb hauv nws txoj kev xaiv, vim nws kim heev.
Kev Lag Luam Hlau thiab Kev Lag Luam Kev Lag Luam tau siv cov khoom siv fluoropolymer tubing los ntawm cov ntaub ntawv zoo li PTFE thiab hoses rau ntau xyoo rau kev hloov cov tshuaj lom neeg los yog cov tshuaj corrosive.Ntau thiab ntau, PTFE tubing yog hloov cov pa roj carbon thiab lwm yam hlau piping uas deteriorates sai.Tam sim no thiab yav tom ntej, PTFE yuav txuas ntxiv ua haujlwm rau kev lag luam hauv cov ntawv thov tseem ceeb.
PTFE Thermal Zoo:
PTFE tubing tuaj yeem tiv taus kub txog 680 ° F rau lub sijhawm txwv.
* Tshaj 500 ° F, cov khoom siv kho tshuab ua ib qho kev txwv
PTFE Hluav taws xob zoo:
PTFE tubing muaj cov khoom siv hluav taws xob zoo heev, qhia los ntawm qhov tsis tshua muaj hluav taws xob tsawg ntawm 2.1 ntawm -40 ° F thiab 480 ° F nyob rau hauv ntau zaus ntawm 5 Hz txog 10 GHz.
PTFE tubing kuj yog ib qho zoo heev insulator nrog nto resistivity ntawm 3.6 X 1012 ohms (txawm tias ntawm 100% txheeb ze humidity).
Lub sij hawm luv luv dielectric zog muaj li ntawm 500 volts / mil (1 mil = 10-3 nyob rau hauv) rau thicknesses ntau tshaj 100 mils mus rau 4000 volts / mil rau nyias nyias.
Qhov sib txawv ntawm PTFE
PCTFE yog homopolymer ntawm chlorotrifluoroethylene (CTFE), hos PTFE yog homopolymer ntawm tetrafluoroethylene.Cov monomers ntawm yav dhau los txawv ntawm qhov tom kawg structurally los ntawm muaj cov tshuaj chlorine atom hloov ib qho ntawm cov fluorine atom.Li no txhua chav rov ua dua ntawm PCTFE muaj chlorine atom nyob rau hauv qhov chaw ntawm fluorine atom.Qhov no tso nyiaj rau PCTFE kom muaj qhov hloov pauv tsawg dua ntawm cov saw hlau thiab yog li qhov kub hloov pauv iav dua.PTFE muaj cov ntsiab lus melting ntau dua thiab muaj crystalline ntau dua li PCTFE, tab sis tom kawg muaj zog thiab tawv dua.Txawm hais tias PCTFE muaj cov tshuaj tiv thaiv zoo heev, nws tseem tsawg dua li ntawm PTFE.PCTFE muaj qis viscosity, siab zog tensile thiab creep tsis kam tshaj PTFE.
PCTFE yog txhaj moldable thiab extrudable thaum PTFE tsis yog.
Yog li, kuv xav hais tias nws nyob ntawm daim ntawv thov ntawm lub valve.Koj puas muaj qhov txwv qhov kub thiab txias?Qhov kev pab cuam kua/vapor yog dab tsi?Zoo li nws yuav ua tau zoo rau feem coob ntawm cov ntawv thov uas siv PTFE, tab sis muaj kev ua txhua yam, tshwj xeeb tshaj yog cov ntawv thov uas PTFE yuav tsum tsis yog PCTFE.
PTFE = polymerPCTFE = Kel-F
Ob leeg yog tsim rau siv rau pob valve rooj.Qhov sib txawv loj yog PCTFE nyuaj dua thiab muaj kev sib txhuam ntau dua.Qhov cuam tshuam ntawm ob qho xwm txheej yog tias nws nyiam xav tau ntau lub zog kom tig lub valve qhib thiab kaw
PS: Tiv tauj peb rau PTFE cov khoom tiav cov qauv dawb
