Permeation ntawm PTFE raj
Qee qhov xwm txheej, kev nkag mus los ntawm cov fluoropolymer tuaj yeem ua rau muaj teeb meem nrog cov kav dej hauv ob sab phlu.
Tam sim no,BESTEFLONTuam txhabTeflon yeeb nkabCov kws tshaj lij yuav teb cov lus nug no rau koj.
Lub permeability ntawm ptfe yeeb nkab yuav ua rau corrosion ntawm cov hlau tiv thaiv txheej, luv luv lub neej ntawm cov yeeb nkab, siab tu nqi, muaj kuab paug thiab kev hem thawj rau kev noj qab haus huv ntawm cov neeg ua haujlwm. Zuag qhia tag nrho, feem ntau, nws nce tag nrho cov nqi ntawm cov tswv cuab!
PTFE molecules yog ntev chains ntawm carbon atoms surrounded los ntawm fluorine atoms. Txhua carbon atom muaj ob lub fluorine atom txuas nrog nws. Muab cov polarity muaj zog thiab txhua cov pa roj carbon monoxide hauv cov saw hlau muaj ob lub fluorine atoms txuas rau nws, qhov no ua rau PTFE ib lub pob txha tawv tawv uas nyob ib puag ncig los ntawm cov fluorinated tiv thaiv, ua rau nws yuav luag tiv taus cov tshuaj yaig.
PTFE muaj cov noncrystallographic thiab crystalline cov qauv, uas yog ntau compact nyob rau hauv kev sib piv. Cov qauv nruj dua, qhov tsawg permeable lawv yog cov roj. Cov qauv siv lead ua ntawm PTFE tuaj yeem hloov kho los txhim kho nws cov permeability.
Feem ntau, cov khoom siv hauv ob sab phlu tuaj yeem siv tau 20 xyoo lossis ntev dua yam tsis muaj kev nkag mus. Txawm li cas los xij, qee zaum, osmoation tshwm sim nyob rau hauv lub lis piam lossis ntau hlis tom qab ib qho khoom siv ua haujlwm. Tom qab kev tshawb fawb, peb pom tias cov kev siv hauv qab no muaj kev cuam tshuam loj heev rau kev nkag mus rau tus nqi:
physicochemical khoom
1. Lub cev me me, xws li helium, dej, lossis carbon dioxide tuaj yeem nkag mus los ntawm PTFE. Qhov no yog vim hais tias cov molecules me me txaus los tso cai rau lawv dhau los ntawm cov qauv ntawm cov polymer nyob rau hauv qhov sib txawv ntawm ib tus neeg polymer molecules.
2.Atoms tshuaj zoo ib yam li fluorine, xws li chlorine thiab bromine, tuaj yeem nkag mus rau hauv cov qauv ntawm PTFE thiab PTFE.
Kub
Raws li qhov kub thiab txias, qhov nkag mus los ntawm PTFE phab ntsa nce nyob rau hauv ib qho kev tsis sib xws. Qhov no yog tshwm sim los ntawm cov hauv qab no:
1. Cov pa roj yuav dhau los ua ntau dua hauv cov polymer raws li qhov kub thiab txias
2. Muaj kev sib pauv ntawm tus kheej atoms ntawm cov saw hlau polymer,
3. Lub ntim polymer nce, ua rau ntau qhov chaw ntawm ib tus neeg cov saw hlau polymer.
Siab
Lub osmotic tus nqi nce nyob rau hauv ib tug linear zam nrog ib tug nce nyob rau hauv cov roj siab.
Tube phab ntsa thickness
Lub phab ntsa thickness ntawm lub hose kuj yuav pab kom txo tau tus nqi nkag. Yog tias kuaj nrog ob txheej txheej polymer npaj los ntawm tib cov khoom, qhov nkag mus los ntawm cov txheej tuab yuav qis dua li ntawm cov txheej nyias nyias. Raws li lub thickness nce, qhov nkag mus rau hauv lub zog yuav ruaj khov, tsis yog txuas ntxiv mus.
Amplitude ntawm kev vibration
Lub amplitude ntawm kev vibration uas tsim los ntawm hose thaum ua hauj lwm muaj kev cuam tshuam zoo rau kev puas tsuaj ntawm lub hose. Yuav tsum muaj kev kho kom haum xeeb. Piv txwv li, siv cov hoses hloov tau yooj yim dua, thiab siv lub tes tsho roj hmab los txo qhov kev puas tsuaj los ntawm kev co.
Qhov zoo ntawm PTFE hmoov
Muaj ntau hom khoom sib txawv thiab cov qauv sib txawv ntawm cov khoom siv raw ntawm lub khw, thiab qhov zoo tsis sib xws. Cov hmoov nplej sib txawv tuaj yeem cuam tshuam cov nyhuv ntawm sintering tawm.
Yuav ua li cas txo cov permeability ntawm PTFE hose?
Ib txoj hauv kev los txo qhov kev nkag mus ntawm PTFE yog ua kom cov crystallinity ntawm cov polymer, lossis% ntawm cov polymer nrog cov qauv crystalline. Txij li thaum PTFE tsis tuaj yeem ua tiav hauv yaj, kev siv tshuab tshwj xeeb yog siv los ua cov ntaub ntawv raw rau hauv cov khoom muaj. Cov txheej txheem tseem ceeb rau kev ua PTFE yog compression molding. Compression molding yog teeb tsa cov qauv polymer los ntawm nyem PFE hmoov rau hauv cov duab thiab tom qab ntawd ci ntawm qhov kub thiab txias. Cov ids hauvPTFE hosestuaj yeem tswj tau thiab txo qis los ntawm kev ua lub hose los ntawm qeeb sintering lossis txawm tias tom qab sintering txheej txheem, uas pab ua kom PTFE molecules ntau crystalline. Cov txheej txheem kev ua haujlwm no tuaj yeem tso qhov khoob me me hauv cov khoom siv, tso cai rau cov txheej txheem dej txav los ntawm nws. Besteflon tau siv dav hauv nws lub tes tsho PTFE processor rau kev tsim khoom thiab kev tswj kom zoo. Hauv cov txheej txheem, peb yuav tau txais qib siab tshaj plaws ntawm osmotic tsis kam.
