ʻO nā ʻaoʻao mua a me hope o ka pōʻai pcb he mau papa keleawe. I ka hana ʻana i nā kaapuni pcb, ʻaʻohe mea inā koho ʻia ka papa keleawe no ka helu kumukūʻai hoʻololi a i ʻole ka helu pālua a me ka unuhi ʻana, ʻo ka hopena hope loa he maʻemaʻe a mālama ʻole. ʻOiai ʻaʻole ʻoliʻoli nā waiwai kino o ke keleawe e like me ka aluminika, ka hao, ka magnesium, a me nā mea ʻē aʻe, ma lalo o ka manaʻo o ka hau, ʻo ke keleawe maʻemaʻe a me ka oxygen e maʻalahi loa i ka oxidation; e noʻonoʻo ana i ka noho ʻana o ka co2 a me ka mahu wai i ka lewa, ka ʻili o ke keleawe a pau Ma hope o ka hoʻopili ʻana me ke kinoea, e hiki koke mai ka hopena redox. Ke noʻonoʻo nei i ka mānoanoa o ka papa keleawe i loko o ka PCB kaapuni he lahilahi, ʻo ke keleawe ma hope o ka hoʻoheheʻe ʻana o ka ea e lilo i kahi kūlana paʻa o ka uila, kahi e hōʻeha nui ai i nā hiʻohiʻona uila o nā kaapuni PCB āpau.

I mea e pale maikaʻi ai i ka oxidation o ke keleawe, a me ka hoʻokaʻawale maikaʻi ʻana i ka welding a me ka non-weld welding ʻāpana o ka pcb kaapuni i ka wā uila, a i mea e mālama maikaʻi ai i ka ʻili o ka pcb kaapuni, ua hana nā ʻenekini ʻenehana i kahi Architectural kūikawā. Nā uhi. Hiki ke hoʻopili maʻalahi ʻia ia mau mea hoʻonaninani ma luna o ka ʻili o ke kaapuni PCB, e hopena i ka mānoanoa o ka ʻāpana pale e pono e lahilahi a pale i ka pilina o ke keleawe a me ke kinoea. Kapa ʻia kēia papa he keleawe, a ʻo ka mea maka i hoʻohana ʻia he solder mask
