Asitikali ndi ndege PCB Nthawi zambiri amakhala pamavuto azachilengedwe, kuphatikiza kutentha / kusinthasintha, chinyezi chambiri komanso chinyezi. Kuphatikiza apo, nthawi zambiri amakumana ndi mankhwala owopsa, zothetsera ma hydrocarbon, fumbi ndi zowononga zina. Ndi PCB yokha yomwe imasonkhanitsidwa kuchokera kuzipangizo zapamwamba kwambiri zopangidwa pogwiritsa ntchito njira zolondola zopangira ndi zomwe zingathe kupirira zovuta muntchito zankhondo komanso malo ogwiritsira ntchito.

Momwe mungapangire ma PCBS ankhondo ndi ndege

Poyerekeza ndi matabwa wamba, ma PCBS amatanthauza kuti ntchito zankhondo ndi malo ogwiritsira ntchito malo amafunikira kukonzedwa mwapadera pakupanga, kupanga ndi kusonkhana.

Mukamasonkhanitsa PCBS kuti mugwiritse ntchito zankhondo ndi ndege, zina zowonjezera ziyenera kuphatikizidwa. Zina mwa izi ndi:

L Gwiritsani ntchito kuzimitsa kutentha pakafunika kutero.

L Onjezerani kutchinjiriza kwina ndi kuwongolera pa zingwe zofunikira.

L Odula PCBS yokhala ndi akiliriki yakutsogolo kwambiri kuti iwateteze m’malo owononga.

Gwiritsani ntchito zigawo zikuluzikulu zankhondo m’malo mogulitsa zinthu.

L Gwiritsani ntchito njira zoyenera zothanirana.

L Sankhani mosamala zida ndi zida zake kuti mupirire kutentha kwambiri. Izi zikuphatikiza Pyralux AP, epoxy laminates (mwachitsanzo FR408) ndi zida zingapo zoyambira zachitsulo.

L Gwiritsani ntchito zida zomalizira zodalirika kwambiri kuti muteteze m’malo ovuta. Zida zokongoletsa kwambiri zomwe zimagwiritsidwa ntchito pamisonkhano yankhondo ndi ndege za PCB ndi monga:

n ENIG

Electrolysis wa faifi tambala ndi golide

n ENEPIG

N yopanda kutsogolera HASL

N leaching siliva

N Waya wamagetsi wamagetsi wamagetsi

N ndi

N golide wolemera

N mfuti

L Imapanga magulu ankhondo ndi ndege zapa PCBS zogwirizana ndi mil-PRF-31032, MIL-PRF-50884 ndi MIL-PRF-55110 miyezo.

L Chonde onetsetsani kupindika mphamvu, mphamvu yolimba, waya m’lifupi, makulidwe, malingaliro, makulidwe azotetezera ndi ma dielectric musanatumize. Onetsetsani kuti mwakonzeka kuzigwiritsa ntchito m’malo ovuta a mafakitale.

Kusunga khola komanso kulimba ndikofunikira pakupanga magulu ankhondo ndi ndege za PCBS. Kulephera kwa PCB kumakhudza kwambiri magwiridwe antchito ndikugwiritsa ntchito bwino ntchitoyi.
