PFA khoom yog dab tsi? Cov ncauj lus kom ntxaws tsom xam thiab daim ntawv thov scenarios
Hauv kev lag luam tshuaj thiab hauv ntau qhov kev thov kev lag luam, kev xaiv cov khoom siv yog qhov tseem ceeb - PFA yog dab tsi? Cov lus nug no feem ntau tshwm sim hauv lub siab ntawm cov kws tshaj lij uas xav tau cov ntaub ntawv uas tiv taus kub thiab corrosion. Hauv tsab xov xwm no, peb yuav muab cov ncauj lus kom ntxaws txog qhov xwm txheej thiab cov khoom ntawm PFA cov ntaub ntawv thiab lawv cov kev siv ntau yam xwm txheej.
PFA yog dab tsi?
PFA (Perfluoroalkoxy) yog fluoropolymer uas yog nyob rau hauv polytetrafluoroethylene (PTFE) tsev neeg.PFA cov ntaub ntawv txhim khu cov ntaub ntawv tus txheej txheem los ntawm kev qhia alkoxy substituents, thiab muaj zoo thermoformability thiab siab dua mechanical zog piv rau PTFE.Cov tshuaj muaj pes tsawg leeg ntawm PFA khoom yog zoo ib yam li cov khoom ntawm PTFE, tab sis zoo xws li cov khoom ntawm PTFE. tab sis vim nws cov txheej txheem ua tau zoo dua thiab pob tshab, PFA muaj qhov zoo dua nyob rau hauv ntau daim ntawv thov uas yuav tsum tau txhaj tshuaj molding precision.
Cov khoom tseem ceeb ntawm PFA cov ntaub ntawv
PFA cov ntaub ntawv yog dav siv rau lawv cov tshuaj tiv thaiv zoo heev thiab thermal stability. Hauv qab no yog qee qhov tseem ceeb ntawm cov ntaub ntawv PFA:
Kev Tiv Thaiv Kub Kub: Cov ntaub ntawv PFA muaj peev xwm tswj tau lawv lub cev thiab tshuaj lom neeg ntawm qhov kub thiab txias, mus txog qhov kub siab tshaj plaws ntawm 260 ° C. Qhov no ua rau PFA yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas xav tau qhov kub thiab txias.

Tshuaj Tiv Thaiv: PFA qhia tau zoo heev tiv thaiv yuav luag txhua yam tshuaj, suav nrog cov acids muaj zog, cov hauv paus thiab cov kuab tshuaj organic. Qhov no ua rau nws nrov tshwj xeeb hauv kev lag luam tshuaj, tshwj xeeb tshaj yog nyob rau hauv cov kav dej thiab cov hlab ntsha uas nqa cov kua corrosive thiab gases.

Tsis tshua muaj kev sib txhuam thiab tsis-stick zog: PFA qhov qis coefficient ntawm kev sib txhuam thiab cov khoom tsis-stick ua rau nws zoo tagnrho rau hauv cov ntawv thov uas tsim nyog los txo qis hnav thiab tiv thaiv adhesion, xws li hauv cov coatings thiab seals.

Hluav taws xob rwb thaiv tsev: PFA muaj cov khoom siv hluav taws xob zoo heev, uas ua rau nws tseem ceeb rau kev siv hauv kev lag luam hluav taws xob thiab hluav taws xob.

Cov cheeb tsam ntawm daim ntawv thov rau PFA
Vim nws cov khoom tshwj xeeb, PFA cov khoom siv dav siv hauv ntau qhov kev lag luam. Cov hauv qab no yog qee qhov tseem ceeb ntawm kev siv:
Cov khoom siv tshuaj lom neeg thiab petrochemical: Vim nws cov tshuaj tiv thaiv zoo heev, PFA feem ntau yog siv los ua cov hlua rau cov kav dej, li qub, twj thiab cov hlab ntsha. Cov khoom siv no xav tau cov tshuaj tiv thaiv siab heev thaum tuav cov kua dej thiab cov pa roj, thiab cov ntaub ntawv PFA tuaj yeem ua kom ntev lub neej ntawm cov khoom siv.

Semiconductor Manufacturing: PFA lub siab purity thiab corrosion kuj ua rau nws yog ib yam khoom tseem ceeb nyob rau hauv semiconductor manufacturing khoom, xws li cov kav dej thiab cov hlab ntsha siv nyob rau hauv zus tau tej cov tshuaj vapor deposition (CVD) systems.

Cov Khoom Siv Kho Mob: Hauv kev kho mob, PFA feem ntau yog siv rau hauv kev tsim cov khoom siv nrog cov kev xav tau biocompatibility siab, xws li catheters thiab sensor vaj tsev.Cov tshuaj inertness thiab thermal stability ntawm PFA cov ntaub ntawv ua kom muaj kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom siv no.

Cov kev soj ntsuam saum toj no muab peb cov duab meej meej ntawm PFA yog dab tsi.PFA yog cov khoom siv fluoropolymer uas yog qhov tseem ceeb hauv ntau qhov kev lag luam.Nws kub tsis kam, tshuaj tiv thaiv, tsis tshua muaj kev sib txhuam, thiab hluav taws xob rwb thaiv tsev cov khoom ua rau nws muaj txiaj ntsig zoo rau ntau yam kev siv hauv tshuaj, hluav taws xob, thiab kev kho mob. Yog tias koj tab tom nrhiav cov khoom siv uas tuaj yeem ua tau zoo hauv cov xwm txheej hnyav, PFA yeej yog qhov kev xaiv zoo tsim nyog xav txog.
