Me pēhea te whakaiti i te wiri o ngā pereti mata karāhe i te wā e patu ana i te PCB?

 

I roto i te hanga hikohiko, he mea tino nui te tika, inā koa i roto i ngā tukanga pēnei i te wero i te PCB (Papa Ara Iahiko Tā). Ko tētahi o ngā mea matua e pā ana ki te tika me te kounga o te wero i te PCB ko te wiri. Ka taea te whakamahi i ngā panera mata karāhe, hei otinga kaha hei whakaiti i te wiri me te whakanui ake i te pai o te hanga.

E mōhiotia ana ngā papa o te karāneti mō tō rātou pumau me te pakari. He mea hanga mai i te karāneti tūturu, ā, he turanga pakari ēnei papa mō ngā momo tikanga tukatuka me te huihuinga. Ina whakamahia ki te tā PCB, ka āwhina i te mimiti me te whakamarara i ngā wiri ka puta mai i te mīhini tā. He mea nui tēnei nā te mea ahakoa he wiri iti noa iho ka taea te whakararu i te tūnga, ka hua ake he PCB hapa, kāore pea e tutuki i ngā paerewa kounga tino pakari.

Nā te hanganga matotoru o te karāhe ka taea e ia te mahi hei ātete ru. Ina mahi te mīhini tā, ka puta he wiri e tukuna ana mā te mata mahi. Ka taea te whakaiti i ēnei wiri mā te whakanoho i ngā taputapu tā ki runga i te papa karāhe. Ko te papatipu me ngā āhuatanga ā-roto o te papa karāhe ka āwhina i te mimiti i te pūngao me te ārai i tōna pānga ki te PCB e tukatukahia ana.

Hei tāpiritanga, ka whakaratohia e te papa o te karāhe he mata mahi papatahi, pumau hoki, he mea nui ki te pupuri i te tika e hiahiatia ana mō te wero i te PCB. Mā te papatahi o te karāhe ka whakarite kia tino tika te tūnga o te taputapu wero ki te PCB, ka whakaitihia te mōrearea o ngā hapa. Mā te whakakotahitanga o te whakaiti wiri me te pumau ka whakapai ake i te tika, ka whakaiti i ngā tere para, ā, i te mutunga ka whakapai ake i te kounga o te hua.

Hei whakarāpopototanga, he mea nui te mahi a ngā panera karāhe ki te whakaiti i te wiri i te wā e tāia ana te PCB. Nā te kaha ki te mimiti i ngā wiri, me te papatahi me te pumau, ka waiho hei taputapu nui i roto i te umanga hanga hiko. Mā te haumi ki ngā panera karāhe, ka taea e ngā kaihanga te whakapai ake i ā rātou tukanga whakaputa, me te whakarite kia tukuna e rātou he PCB kounga teitei e tutuki ai ngā hiahia o ngā hiko hou.
