Tub rog thiab aviation PCB feem ntau raug rau cov xwm txheej ib puag ncig hnyav, suav nrog nce siab/hloov pauv kub, huab cua txias thiab av noo. Ntxiv mus, lawv feem ntau raug rau cov tshuaj hnyav, cov tshuaj hydrocarbon, hmoov av thiab lwm yam kuab paug. Tsuas yog PCB sib sau ua ke los ntawm cov ntaub ntawv zoo tshaj plaws tsim los siv cov txheej txheem tsim khoom raug tuaj yeem tiv taus qhov hnyav hauv kev siv tub rog thiab kev siv dav hlau.

Yuav tsim cov tub rog thiab kev ya dav hlau PCBS li cas

Muab piv rau cov laug cam, PCBS txhais tau tias kev siv tub rog thiab kev siv dav hlau xav tau kev ua tshwj xeeb hauv kev tsim qauv, tsim khoom thiab sib dhos.

Thaum sib sau PCBS rau kev siv tub rog thiab kev siv dav hlau, yuav tsum muaj cov yam ntxwv ntxiv. Qee qhov ntawm no suav nrog:

L Siv tus neeg sawv cev ua kom sov thaum tsim nyog.

L Ntxiv kev tiv thaiv ntxiv thiab tiv thaiv kab rau kab tseem ceeb.

L Tsho PCBS nrog cov tshuaj acrylic zoo los tiv thaiv lawv los ntawm ib puag ncig kev xeb.

Siv cov khoom siv nrog cov tub rog tshwj xeeb tshaj li cov khoom lag luam qib.

L Siv cov txheej txheem txiav kom tsim nyog.

L Ua tib zoo xaiv cov khoom thiab cov khoom kom tiv taus qhov kub siab. Cov no suav nrog Pyralux AP, epoxy laminates (piv txwv li FR408) thiab ntau yam khoom siv hlau.

L Siv cov ntaub ntawv pov thawj tsis txaus ntseeg txhawm rau txhim kho kev tiv thaiv hauv cov xwm txheej hnyav. Cov khoom siv zoo nkauj tshaj plaws uas siv hauv kev ua tub rog thiab dav hlau PCB sib dhos suav nrog:

n ENIG

Electrolysis ntawm npib tsib xee thiab kub

n NPE

N tsis muaj HASL

N leaching nyiaj

N Electrolytic hlau weldable kub

N yog

N hnyav kub

N phom

L Ua cov tub rog thiab qib kev ya dav hlau PCBS ua raws li cov txheej txheem mil-PRF-31032, MIL-PRF-50884 thiab MIL-PRF-55110.

L. Xyuas kom koj tau npaj siv lawv nyob rau ib puag ncig kev lag luam hnyav.

Kev saib xyuas kom zoo thiab siv tau ntev yog qhov tseem ceeb thaum tsim cov tub rog thiab qib aviation PCBS. PCB tsis ua haujlwm tuaj yeem cuam tshuam loj rau kev ua haujlwm ntawm daim ntawv thov thiab yog li ua tiav ntawm lub luag haujlwm tag nrho.
