Me pēhea te aromatawai i te pānga o ngā wāhanga karāhe ki te pumau whānui o ngā mīhini keri me te mira PCB?

He taputapu nui ngā mīhini keri me te mira PCB e whakamahia ana i roto i te hanga papa hiko tānga (PCB). Ka whakamahia e ēnei mīhini ngā taputapu tapahi hurihuri e tango ana i ngā rauemi mai i te papa PCB mā te whakamahi i ngā nekehanga hurihuri tere-teitei. Kia pai ai te mahi a ēnei mīhini, kia whai hua hoki, he mea nui kia pumau, kia pakari hoki ngā wāhanga mīhini, pērā i te karāhe e whakamahia ana mō te moenga mīhini me te hanganga tautoko.

He rauemi rongonui te karāneti e whakamahia ana i roto i te hanganga o ngā mīhini wiri me te mira PCB. He tino pai ngā āhuatanga miihini me te wera o tēnei kōhatu tūturu, ā, he mea tino pai mō te hanga i ngā wāhanga mīhini. Ina koa, he tino pakari te karāneti, he kaha teitei, he iti te horapa wera, ā, he tino pumau. Mā ēnei āhuatanga ka noho pumau te mīhini, ka kore hoki e wiri i te wā e whakamahia ana, ka piki ake te tika me te whai hua.

Ka taea te aromatawai i te pānga o ngā wāhanga karāhe ki te pumau hihiri whānui o ngā mīhini keri me te mira PCB mā roto i ngā huarahi maha. Ko tētahi o ngā tikanga e whakamahia whānuitia ana ko te tātari huānga mutunga kore (FEA). He tikanga whakatauira te FEA e uru ana ki te wehewehe i te mīhini me ōna wāhanga ki ngā huānga iti ake, ngāwari ake te whakahaere, kātahi ka tātarihia mā te whakamahi i ngā rauropi rorohiko matatau. Ka āwhina tēnei tukanga ki te aromatawai i te whanonga hihiri o te mīhini, ā, ka matapae me pēhea tana mahi i raro i ngā āhuatanga uta rerekē.

Mā te FEA, ka taea te aromatawai tika i te pānga o ngā wāhanga karāhe ki te pumau, te wiri, me te haruru o te mīhini. Mā te pakari me te kaha o te karāhe ka noho pumau te mīhini i raro i ngā āhuatanga whakahaere rerekē, ā, mā te iti o te horapa wera ka mau tonu te tika o te mīhini i roto i te whānuitanga o te pāmahana. Hei tāpiri, mā ngā āhuatanga whakamātao wiri o te karāhe ka tino whakaiti i ngā taumata wiri o te mīhini, ka pai ake te whai hua me te tika.

Haunga te FEA, ka taea hoki te whakahaere whakamātautau ā-tinana hei aromatawai i te pānga o ngā wāhanga karāhe ki te pumau whānui o ngā mīhini keri me te mira PCB. Ko ēnei whakamātautau ko te tuku i te mīhini ki ngā āhuatanga wiri me te utaina rerekē, me te ine i tana urupare. Ka taea te whakamahi i ngā hua i puta hei whakatikatika i te mīhini me te mahi i ngā whakarerekētanga e tika ana hei whakapai ake i tōna pumau me tana mahi.

Hei whakamutunga, he mea nui te mahi a ngā wāhanga karāhe ki te whakarei ake i te pumau o ngā mīhini keri me te mira PCB. He tino pai ngā āhuatanga miihini me te wera e whakarite ana kia mau tonu te mīhini, kia kore hoki e wiri i te wā e mahi ana, ā, ka pai ake te whai huatanga me te tika. Mā te FEA me te whakamātautau ā-tinana, ka taea te aromatawai tika i te pānga o ngā wāhanga karāhe ki te pumau me te mahi a te mīhini, kia tino pai ai te mahi a te mīhini.
