PTFE ntaub, los yog polytetrafluoroethylene npuag, yog cov ntaub ntawv ua haujlwm zoo uas tau siv dav hauv ntau lub teb vim nws cov dej tsis zoo, ua pa, cua tsis muaj zog, thiab sov so.
Cov tub ntxhais ntawm PTFE ntaub yog polytetrafluoroethylene microporous zaj duab xis, uas muaj ib tug tshwj xeeb microporous qauv nrog ib tug pore loj ntawm tsuas yog 0.1-0.5 microns, uas yog npaum li cas me dua lub cheeb ntawm ib tug dej molecule, tab sis ntau txhiab lub sij hawm loj dua ib tug dej vapor molecule. Yog li ntawd, PTFE npuag tuaj yeem thaiv qhov nkag mus ntawm cov tee dej thaum tso dej vapor kom dhau los ntawm kev ywj pheej, ua tiav kev sib xyaw zoo ntawm cov dej tsis zoo thiab ua pa. Cov ntaub no kuj muaj cov khoom zoo windproof, thiab nws cov qauv microporous tuaj yeem tiv thaiv huab cua convection, yog li tswj kom sov hauv cov khaub ncaws.
1. Cov khoom tseem ceeb ntawm PTFE
PTFE yog thawj zaug tsim los ntawm DuPont hauv xyoo 1940 thiab paub tias yog "King of Plastics" rau nws qhov kev ua tau zoo. Cov qauv molecular ntawm PTFE yog qhov ruaj khov heev, thiab lub zog sib zog ntawm cov pa roj carbon atoms thiab fluorine atoms yog siab heev, uas muab PTFE cov khoom nram qab no zoo kawg li:
● Waterproofness:PTFE fabrics muaj cov khoom siv dej tsis zoo, thiab cov dej molecules tsis tuaj yeem nkag mus rau lawv qhov chaw, yog li lawv feem ntau siv los ua cov khaub ncaws tsis zoo thiab khoom siv.
● Breathability:Txawm hais tias tsis muaj dej, PTFE fabrics muaj cov qauv microporous uas tso cai rau cov dej vapor hla dhau, tswj kev nplij siab ntawm cov neeg hnav. Cov cuab yeej no ua rau nws yog qhov kev xaiv zoo tshaj plaws rau sab nraum zoov ncaws pob thiab cov khaub ncaws tiv thaiv.
● Tshuaj tiv thaiv:PTFE tsis tshua muaj zog rau feem ntau cov tshuaj thiab yuav luag tsis cuam tshuam los ntawm corrosive tshuaj xws li acids, alkalis, thiab cov kuab tshuaj.
● Kub tiv taus:PTFE fabrics tuaj yeem nyob ruaj khov ntawm qhov kub thiab txias, thiab nws qhov kev ua haujlwm kub yog los ntawm -200 ° C txog + 260 ° C, haum rau qhov kub thiab txias.
● Tsawg txhuam coefficient:PTFE muaj ib tug heev du nto thiab tsis tshua muaj kev sib txhuam coefficient, yog li nws yog feem ntau siv nyob rau hauv industrial qhov chaw uas yuav tsum tau txo kev sib txhuam.
● Kev laus tsis kam:PTFE yog tsis tshua muaj resistant rau ultraviolet rays thiab lwm yam ib puag ncig, thiab tsis yog nws cov laus tom qab siv mus ntev.
Ntawm lawv, qhov tseem ceeb tshaj plaws ntawm PTFE ntaub yog nws cov tshuaj tiv thaiv corrosion. Nws tuaj yeem tiv taus cov kua qaub uas muaj zog, muaj zog alkalis thiab lwm yam tshuaj lom neeg, yog li nws tau siv dav hauv cov khaub ncaws tshwj xeeb xws li nuclear, lom thiab tshuaj tiv thaiv khaub ncaws thiab tshuaj tiv thaiv khaub ncaws. Tsis tas li ntawd, PTFE npuag kuj muaj cov kab mob tua kab mob, tshuaj tiv thaiv kab mob, tiv thaiv kab mob thiab lwm yam haujlwm, ua rau nws tseem ceeb hauv kev tiv thaiv kev kho mob.
Hauv kev siv tiag tiag, PTFE npuag yog sib xyaw nrog nylon, polyester thiab lwm yam ntaub los ntawm cov txheej txheem lamination tshwj xeeb los ua ob-hauv-ib lossis peb-hauv-ib daim ntaub. Cov ntaub sib xyaw no tsis tsuas yog khaws cov kev ua tau zoo ntawm PTFE zaj duab xis, tab sis kuj muaj kev nplij siab thiab ua haujlwm ntev ntawm lwm cov ntaub.
2. Daim ntawv thov teb ntawm PTFE fabrics
Vim muaj cov khoom tshwj xeeb ntawm PTFE fabrics, nws tau siv dav hauv ntau lub teb:
● Cov khaub ncaws sab nraum zoov:PTFE fabrics feem ntau yog siv los ua cov tsho tsis muaj dej thiab ua pa, ris thiab khau, haum rau kev ua si sab nraum zoov xws li roob thiab caij ski.
● Cov khaub ncaws tiv thaiv kev lag luam:Nws cov tshuaj tiv thaiv thiab kub tsis kam ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tiv thaiv khaub ncaws hauv tshuaj lom neeg, roj av thiab lwm yam lag luam.
● Cov khoom siv kho mob:PTFE fabrics yog siv los ua cov ris tsho phais, tshuaj tua kab mob thiab lwm yam khoom siv kho mob kom paub meej qhov chaw tsis muaj menyuam.
● Lim cov ntaub ntawv:Cov qauv microporous ntawm PTFE ua rau nws cov khoom siv lim tau zoo, uas yog siv dav hauv kev ua kom huv hauv huab cua, kev kho dej thiab lwm yam haujlwm.
● Aerospace:PTFE qhov kub tsis kam thiab tsis tshua muaj kev sib txhuam coefficient ua rau nws siv hauv aerospace teb, xws li cov ntsaws ruaj ruaj thiab cov ntaub ntawv rwb thaiv tsev.
3. Kev tiv thaiv ib puag ncig ntawm PTFE fabrics
Txawm hais tias PTFE fabrics muaj ntau qhov zoo, lawv cov kev tiv thaiv ib puag ncig kuj tau nyiam ntau yam. PTFE yog ib qho nyuaj-rau-degrade cov khoom, thiab nws yuav muaj qee yam cuam tshuam rau ib puag ncig tom qab muab pov tseg. Yog li, yuav ua li cas rov ua dua thiab pov tseg ntawm PTFE fabrics tau dhau los ua qhov teeb meem tseem ceeb. Tam sim no, qee lub tuam txhab tab tom tsim cov ntaub ntawv PTFE rov ua dua los txo lawv qhov cuam tshuam rau ib puag ncig.
4. Cov ntsiab lus
PTFE fabrics tau dhau los ua cov khoom siv rau ntau daim ntawv thov high-end vim lawv cov dej tsis zoo, ua pa, tshuaj tiv thaiv, kub tsis kam thiab lwm yam khoom. Txawm hais tias nws yog kev ua kis las sab nraum zoov, kev tiv thaiv kev lag luam, lossis kev kho mob thiab aerospace teb, PTFE fabrics tau qhia lawv qhov tshwj xeeb zoo. Txawm li cas los xij, nrog rau kev paub txog ib puag ncig, yuav ua li cas zoo dua nrog cov khib nyiab ntawm PTFE fabrics yuav dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thiab kev loj hlob yav tom ntej.
