Ke noi a PCB kamaaina kaapuni papa i nā mea āpau a hiki ke ʻike ʻia ma kahi o nā huahana uila āpau. Hāpai ka hoʻomohala ʻana i ka ʻepekema a me ka ʻenehana i ka ulu ʻana o ka ʻoihana kaapuni PCB, a he ʻoi aku ka kiʻekiʻe a me ka kiʻekiʻe o nā koi no nā papa, ka pololei a me ka hilinaʻi o nā mea. Nui a hewahewa nā ʻano papa kaapuni PCB ma ka mākeke, a paʻakikī e hoʻokaʻawale i ka maikaʻi. Ma kēia mea, ʻo ka mea aʻe e aʻo iā ʻoe i kekahi mau ʻano e ʻike ai i ka papa kaapuni PCB.

ʻO ka mea mua, ke hoʻokolokolo mai ka helehelena

1. Ka helehelena o ka weld

Ma muli o ka nui o nā ʻāpana PCB, inā ʻaʻole maikaʻi ke kuʻihao, e hāʻule wale nā ​​ʻāpana PCB, kahi e hoʻopili nui ai i ka maikaʻi kuʻihao a me ka hiʻona o ka PCB. No laila, he mea nui ia e wili paʻa.

Nā kānāwai maʻamau no nā ana a me nā mānoanoa

Ma muli o ka ʻokoʻa o ka mānoanoa o ka papa PCB i ka papa PCB maʻamau, hiki i nā mea hoʻohana ke ana a hōʻoia e like me kā lākou koi ponoʻī.

3. ʻO ke kukui a me ke kala

ʻO ka maʻamau uhi ʻia ka papa PCB kūwaho me ka ʻīnika e pāʻani ai i ke ʻano o ka hoʻohuihui, inā ʻaʻole huali ke kala o ka papa, ʻoi aku ka liʻiliʻi o ka inika, e hōʻike ana ʻaʻole maikaʻi ka papa hoʻonoho ponoʻī.

ʻO ka lua, mai ka papa e hoʻokolokolo

1. He maʻalahi a maʻalahi hoʻi ka pepa HB maʻamau i ka deformation a me ka haki, no laila hiki ke hana i hoʻokahi panela. ʻO ka waihoʻoluʻu o ka ʻāpana he melemele ʻeleʻele, me ka ʻala hoihoi, a ʻeleʻele a lahilahi ka uhi keleawe.

2, hoʻokahi 94V0, CEM-1 papa, ʻoi aku ke kiʻekiʻe o ke kumukūʻai ma mua o ka papa, ʻāpana melemele ke aniani ʻeleʻele, hoʻohana nui ʻia no nā papa ʻoihana a me nā papa mana me nā koina helu ahi.

3. He kiʻekiʻe ke kumu kūʻai o ka papa aniani aniani, ka ikaika maikaʻi a me nā ʻaoʻao ʻelua ʻōmaʻomaʻo. ʻO ke kumu, ʻo ka hapa nui o nā papa PCB i hana ʻia i kēia mea. He mea ʻole ke kala o ka inika paʻi PCB e laumania, ʻaʻole hiki ke loaʻa i ke keleawe wahaheʻe a me ka huʻa ʻana i ka hanana.

Ke ʻike nei i nā kiko i luna, ʻaʻole ia he mea paʻakikī e ʻike i ka PCB papa kaapuni.
