Ezempi nezindiza PCB zivame ukuba ngaphansi kwezimo ezinzima zemvelo, kufaka phakathi amazinga okushisa aphakeme / aguquguqukayo, umswakama omkhulu nomswakama. Ngaphezu kwalokho, bavame ukuvezwa amakhemikhali anokhahlo, izixazululo ze-hydrocarbon, uthuli nokunye ukungcola. I-PCB kuphela ehlanganiswe kusuka ezintweni ezisezingeni eliphakeme ezenziwe ngokusebenzisa izindlela ezifanele zokukhiqiza ezingamelana nezimo ezinzima ekusetshenzisweni kwezempi nakwezindiza.

Ungayakha kanjani i-PCBS yezempi neyezindiza

Uma kuqhathaniswa namabhodi ajwayelekile, ama-PCBS asho ukuthi izinhlelo zamasosha nezasemkhathini zidinga ukucutshungulwa okukhethekile ekwakhiweni, ekwenziweni nasekuhlanganeni.

Lapho kuqoqwa ama-PCBS ezinhlelo zempi nezokundiza, kufanele kufakwe ezinye izici. Ezinye zazo zifaka:

L Sebenzisa umenzeli osakaza ukushisa lapho kudingeka.

L Faka ukuvikelwa okwengeziwe nokugxila ezintanjeni ezibucayi.

L Coat PCBS enekhwalithi ephezulu ye-acrylic spray yokuzivikela ezindaweni ezonakalisayo.

Sebenzisa izinto ezinokucaciswa kwezempi kunokuba nezinto zebanga lokuhweba.

L Sebenzisa izindlela ezifanele zokuqeda.

L Khetha ngokucophelela izinto zokwakha nezakhi ukumelana namazinga okushisa aphezulu. Lokhu kufaka phakathi iPyralux AP, i-epoxy laminates (isb. FR408) nezinto zokwenziwa zensimbi ezahlukahlukene.

L Sebenzisa izinto zokuqedela ezinokwethenjelwa ngokwedlulele ukuthuthukisa ukuvikelwa ezimeni ezinzima. Izinto ezivame kakhulu zokuhlobisa ezisetshenziswa emhlanganweni wezempi nowezindiza we-PCB zifaka:

n ENIG

Ukuhlolwa kwe-nickel negolide

n ENEPIG

N HASL engenakho ukuhola

N leaching isiliva

N Intambo ye-Electrolytic yegolide e-weldable

UN ngu

N igolide elisindayo

N isibhamu

L Ikhiqiza ibanga lezempi nelezindiza i-PCBS ehambisana namamil-PRF-31032, MIL-PRF-50884 kanye namazinga we-MIL-PRF-55110.

L Sicela uqinisekise amandla okugoba, amandla ebhondi, ububanzi bocingo, ukujiya, ukuxazulula, ukushuba kokumboza okuvikelayo ne-dielectric kahle ngaphambi kokuthunyelwa. Qiniseka ukuthi usukulungele ukuwasebenzisa ezindaweni ezinzima zezimboni.

Ukugcina ikhwalithi nokuqina kubalulekile lapho kuklanywa ibanga lempi nelokundiza nge-PCBS. Ukwehluleka kwe-PCB kungathinta kakhulu ukusebenza kohlelo lokusebenza futhi ngaleyo ndlela kube impumelelo yempokophelo ephelele.
